FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with Parkinson’s disease is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about Parkinson’s disease, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to Parkinson’s disease, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on Parkinson’s disease. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to Parkinson’s disease, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on Parkinson’s disease. The Editors

CHAPTER 1. STUDIES ON PARKINSON’S DISEASE Overview In this chapter, we will show you how to locate peer-reviewed references and studies on Parkinson’s disease.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and Parkinson’s disease, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “Parkinson’s disease” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •

Parkinson's Disease and Aided AAC: Some Evidence from Practice Source: International Journal of Language and Communication Disorders. 35(3): 377389. July 2000. Contact: Available from Taylor and Francis Inc. 1900 Frost Road, Suite 101, Bristol, PA 19007. Summary: Clinical observation shows that people with Parkinson's disease (PD) seem to have different training needs from other adult client groups in developing effective use of aided augmentative and alternative communication (AAC). This study was developed in response to these observations. One of the main aims of this preliminary study was to elicit the experiences and attitudes of speech and language therapists in

Parkinson’s Disease

this specific area of their practice as the basis for future efficacy research and clinical practice. Thirty speech and language therapists were questioned about their experiences introducing low and high tech AAC devices to this client group. Of particular interest was the discovery of the factors identified by the therapists as influencing their introduction of aided AAC to someone with PD and affecting implementation and successful use. Some of the factors reported were disease specific such as motor problems and physical inability to use the AAC device. Other factors were more general such as caregivers not offering adequate support. These factors are relevant to the process of introducing aided AAC to other adult client groups. The authors conclude with a discussion of the implications for future research and practice; they emphasize the need to include people with PD and their caregivers in practice development. One appendix reprints the questionnaire used in the study. 1 figure. 3 tables. 31 references. •

Contact: Available from American Speech-Language-Hearing Association (ASHA). Product Sales, 10801 Rockville Pike, Rockville, MD 20852. (888) 498-6699. TTY (301) 8970157. Website: www.asha.org. Summary: This article reports on a study comparing the discourse comprehension abilities of patients with Huntington disease (HD) or Parkinson's disease (PD) to those of age matched control participants with no brain damage. Results from the Discourse Comprehension Test indicated that patients with HD and PD, even those with mild or no dementia, are at risk for discourse comprehension difficulties. Although the patients with HD and PD adequately perceived main information, they had problems processing detailed or implied information. Correlational findings suggested a strong relationship between HD and PD patients' general cognitive decline and their discourse comprehension difficulties. The authors present suggestions for assessing and treating the discourse comprehension abilities of patients with HD and PD. 1 figure. 5 tables. 88 references. (AA-M).



Voice Characteristics in the Progression of Parkinson's Disease Source: International Journal of Language and Communication Disorders. 35(3): 407418. July 2000. Contact: Available from Taylor and Francis Inc. 1900 Frost Road, Suite 101, Bristol, PA 19007. Summary: This article reports on a study that examined the acoustic and perceptual voice characteristics of patients with Parkinson's disease (PD) according to disease severity. The perceptual and acoustic voice characteristics of 30 patients with early stage PD and 30 patients with later stage PD were compared with data from 30 normal control subjects. Voice recordings consisted of prolongation of the vowel 'a', scale singing, and a 1 minute monologue. In comparison with controls and with previously published normative data, both early and later stage PD patients' voices were characterized perceptually by limited pitch and loudness variability, breathiness, harshness, and reduced loudness. High modal pitch levels also characterized the voices of males in both early and later stages of PD. Acoustically, the voices of both groups of PD patients demonstrated lower mean intensity levels and reduced maximum phonational frequency ranges in comparison with normative data. Although less clear, the data from this study also suggested that the PD patients' voices were characterized by excess jitter, a high speaking fundamental frequency for males, and a reduced fundamental

frequency variability for females. While several of these voice features did not appear to deteriorate with disease progression, some aspects (breathiness, monopitch and monoloudness, low loudness, and reduced maximum phonational frequency range) were worse in the later stages of PD. Tremor was the sole voice feature which was associated only with later stage PD. 4 tables. 33 references. •

Burning Mouth in Parkinson's Disease Sufferers Source: Gerodontology. 15(2): 73-78. 1998. Contact: Available from Gerodontology Association. Department of Prosthetic Dentistry, St. Bartholomew's and the Royal London School of Medicine and Dentistry, Turner Street, London E1 2AD, United Kingdom. Summary: This article reports on a study undertaken to determine the prevalence of burning mouth syndrome (BMS) in a population of patients with Parkinson's disease (PD). The study also assessed the use of pain profiles in identifying the type of burning sensation experienced. Subjects were surveyed by means of a one time mailed questionnaire for which ethical approval had previously been granted. BMS was reported by 24 percent of respondents; the pain profiles were completed by 17 of the patients with BMS. None of the patients reported burning before the onset of PD. The incidence of BMS in patients with Parkinson's disease is 5 times greater than that of the general population. The reason for this is uncertain but the result has implications for the future care of PD patients and indicates the need for increased dental input at PD outpatient clinics. The authors hypothesize that because 96 percent of the sample with BMS were on levodopa medication this may be an influential factor in the cause of the burning sensation. There was no significant difference in the prevalence of BMS between dentate, partially dentate, and edentate subjects, which suggests that Candida may not have been an important factor in this population. 1 figure. 2 tables. 22 references.

Federally Funded Research on Parkinson’s Disease The U.S. Government supports a variety of research studies relating to Parkinson’s disease. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to Parkinson’s disease. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore Parkinson’s disease. The following is typical of the type of information found when searching the CRISP database for Parkinson’s disease:

Parkinson’s Disease



Project Title: A MODEL FOR INFLAMMATION AND PD Principal Investigator & Institution: Bolin, Laurel M.; Parkinson's Institute 1170 Morse Ave Sunnyvale, Ca 94089 Timing: Fiscal Year 2001; Project Start 10-APR-2000; Project End 31-MAR-2003 Summary: (adapted from applicant's abstract): The long term goal of this work is to identify inflammatory mechanisms underlying the neurodegeneration of Parkinson's disease so that target-specific therapeutics can be designed. Emerging evidence has led investigators to the hypothesis that inflammatory processes are involved in nigrostriatal degeneration which is the pathological hallmark of Parkinson's disease. They propose to determine the relationship between inflammatory cytokine activation and dopaminergic cell damage in the model of 1-methyl-4-phenyl-1,2,3,6tetrahydropyridine (MPTP)-induced mouse nigrostriatal degeneration. While there is accumulating post-mortem data suggesting an ongoing immune activation in the parkinsonian substantia nigra, the role of the inflammatory cytokines, the mediators of the immune response, as well as the identity of the immunoeffector cells that produce them remain unclear. These multifunctional cytokines that regulate the inflammatory cascade are interleukin-lBeta (IL-1Beta), tumor necrosis factor alpha (TNFalpha) and IL6. These cytokines may have both immunotoxic and neuroprotective activities in the CNS. This proposal is a first step in determining their role in nigrostriatal degeneration. Specifically the investigators will correlate striatal dopamine depletion with the induction of IL-1Beta, TNFalpha and IL-6 proteins in response to MPTP. Further, they will identify and quantify the immunoeffector cell(s) responsible for specific cytokine production in the striatum where dopaminergic projections are damaged and in the substantia nigra where cytokine production could affect dopaminergic neuron cell bodies. To analyze the mechanisms through which astrogliosis and microglia infiltration occur, they will examine glial growth factors and chemoattractants in primary cultures of astrocytes and microglia treated with MPTP. An understanding of inflammatory induction in the MPTP model will provide important clues as to the role of cytokines in neurodegenerative processes. This knowledge could then be applied to cytokine- and cell-specific strategies for anti-inflammatory therapeutic intervention in Parkinson's disease.

Project Title: A VACCINE APPROACH TO PARKINSON'S DISEASE Principal Investigator & Institution: Morgan, David G.; Pharmacology and Therapeutics; University of South Florida 4202 E Fowler Ave Tampa, Fl 33620 Timing: Fiscal Year 2002; Project Start 01-FEB-2002; Project End 31-JAN-2004 Summary: (provided by applicant) Recent work evaluating gene defects leading to Parkinson's Disease (PD) suggests that accumulation of alpha-synuclein may be a critical step in the pathogenic mechanisms leading to Lewy body Parkinsonism. One of us (RM) has developed a rat model of alpha-synuclein over-expression which results in long term elevations of synuclein production and concomitant degeneration of tyrosine hydroxylase neurons in substantia nigra. Because the model uses intracranial genetransfer with viral vectors, it has considerable versatility compared to transgenic models, where over-expression is constant throughout the lifespan. Vaccines, while traditionally viewed as prophylactic approaches to disease, are increasingly being viewed as therapeutic adjuncts in cancer and cardiovascular disease. Others of us (DM and KU) have found that immunization of transgenic mouse models of amyloid overexpression with the All peptide, is surprisingly effective in reducing the Alzheimer

phenotype, both pathologically and behaviorally, that develops in this model of the disease. This application will use the new rat model of alpha-synuclein over expression to test the hypothesis that vaccination against alpha-synuclein could diminish the toxicity of this agent towards dopamine producing neurons. We will use immunization with whole recombinant protein and synthetic peptides and immunization with DNA vaccines. Initial studies will verify that these vaccination regimens can indeed produce high antibody titers in rats, and determine the active immunization regimen(s) that leads to high stable titers. We will next test the hypothesis that antibodies against synuclein produced by these vaccines can arrest the neurotoxicity of dopaminergic neurons caused by alpha-synuclein over expression. Additionally, we will examine direct injections of anti-synuclein antibodies into the brain, bypassing the blood-brain barrier, to evaluate the effectiveness of this approach in rescuing dopaminergic neurons. Success will encourage further development of a vaccine as a therapeutic agent in PD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Principal Investigator & Institution: Davies, Kelvin J.; Gerontology; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2001; Project Start 01-FEB-2000; Project End 31-JAN-2005 Summary: We are interested in a possible link between oxidative stress, aging and neurodegenerative diseases. In recent studies of adaptation to oxidative stress we have identified several previously unknown genes (in addition to confirming the overexpression of several known genes) that appear to provide stress protection in isolated hamster cells in culture. These "adapt" genes include: adapt15, adapt33, adapt66, adapt73, adapt78, and adapt 116. Although our studies indicate that full adaptation depends upon both transcription and translation, it is not clear which genes are actually required. Although each of these newly discovered genes is worthy of detailed study, adapt78 whose mRNA levels increase more than 50 fold in adaptation, in particular stands out. In screening studies employing autopsy samples from human brains, we have now found that the human homologue of adapt78 exhibits extremely high levels of expression in brain autopsy samples from Alzheimer's disease patients, and low levels of expression in brain samples encompassing the substantia nigra from patients who died with Parkinson's disease. Recently, it has become clear that our adapt78 is identical to (or at least highly homologous with) the simultaneously independently discovered Down syndrome critical region 1 (DSCR1) gene of chromosome 21. Furthermore, two different isoforms of both adapt78 and DSCR1 are differentially expressed; corresponding to differentially spliced forms of exons 1-5, 6, 7 and exons 4-5, 6, 7. We propose to now carefully study expression of both isoforms of the human adapt78 gene in different brain regions, using the more sensitive techniques of RT-PCR and in situ hybridization. We plan to study adapt78 expression as a function of age, in brain autopsy samples from otherwise healthy individuals, since adapt78 expression may well vary with age. We will perform detailed studies of brain samples from Alzheimer's disease patients, Parkinson's disease patients, and Down syndrome patients in order to carefully determine both qualitative and quantitative differences in expression of both isoforms of adapt78 mRNA. Localization of adapt78 mRNA expression by cell type will also be studied. We also will synthesize and characterize the (1-5, 6, 7 and 4-5, 6, 7) Adapt78 proteins and generate antibodies to them in order to study expression of the actual proteins in all cell and brain samples. In cell culture studies, with PC-12 cells, we will test the hypothesis that inducible overexpression of

Parkinson’s Disease

adapt78 may confer an oxidative stress resistance phenotype. We will also test the ability of inducible adapt78 overexpressing cells to overcome the lethal oxidizing effects of glutathione deficiency, caused by expression of antisense message to gamma glutamylcysteine synthetase. These studies will allow us to begin to investigate our hypothesis that aging, and perhaps certain neurodegenerative diseases, involving defects in the expression of adapt78 and other adaptive genes required to cope with the deleterious effects of oxidative stress.

Project Title: ANALYSIS OF TORSIN PROTEIN FUNCTION IN C. ELEGANS Principal Investigator & Institution: Caldwell, Guy A.; Biological Sciences; University of Alabama in Tuscaloosa Tuscaloosa, Al 35487 Timing: Fiscal Year 2003; Project Start 01-FEB-2003; Project End 31-JAN-2006 Summary: (provided by applicant): Dystonia is estimated to be six times more prevalent than Huntington's Disease, ALS, or Muscular Dystrophy. However, as few as 5% of the over 350,000 persons in North America estimated to be affected have been correctly diagnosed and are under treatment (NIH Budget Office). The most severe early-onset form of this disorder has been linked to a mutation in a human gene named TOR1A that encodes torsinA, a protein that is also localized to inclusions in the brains of Parkinson's patients termed Lewy bodies. While a causative genetic mutation has been identified, the cellular mechanisms of pathogenesis underlying dystonia remain unknown. We are applying the advantages of the model organism, Caenorhabditis elegans, towards a detailed analysis of two specific torsin-related gene products in this nematode. The chromosomal positioning of these genes suggests that they may represent a functionally co-expressed unit and preliminary studies from our laboratory indicate they act neuronally. Phylogenetic analysis of the torsin family indicates these proteins share distant sequence similarity with the functionally diverse AAA+ family of proteins. We have determined that ectopic overexpression of a C. elegans torsin homolog results in a reduction of polyglutamine repeat-induced protein aggregation in a manner similar to that previously reported for molecular chaperones. The suppressive effects of torsin overexpression quantitatively persisted as animals aged. Antibody staining of transgenic animals using antisera specific to TOR-2 indicated this protein was highly localized to sites of protein aggregation. We propose to extend these preliminary studies through a combination of reverse genetic approaches designed to investigate the cellular role of torsin proteins in the nematode. The specific aims of the proposed project include: 1) to determine what phenotypes are associated with C. elegans torsin homologues; 2) to define sites of C. elegans torsin protein function; and 3) to determine potential effectors of torsin activity. These studies will further our understanding of the molecular mechanisms responsible for early-onset torsion dystonia. Moreover, the aberrant protein deposition associated with diverse neurodegenerative disorders like Parkinson's Disease and those caused by polyglutamine expansion such as Huntington's Disease warrants further investigation of any putative neuroprotective effects of torsins.

Studies

Timing: Fiscal Year 2002; Project Start 11-MAR-2002; Project End 31-DEC-2003 Summary: (provided by applicant) Nitric oxide (NO) acts as an essential antiproliferative signal during tissue differentiation and development. We have recently found that we can inhibit NO production and cause an increase in the number of dividing cells in the adult rodent brain by introducing NO synthase (NOS) inhibitors into brain ventricles. This increase was evident in several areas of the adult brain; significantly, we showed this effect in the areas which have very low levels of neurogenesis, including the cortex and striatum. In this proposal we plan to examine whether introducing NOS inhibitors into brains previously lesioned by neurotoxic agents can induce proliferation of nigrostriatal neurons. We also propose to use a line of transgenic mice, where neural stem cells are marked by GFP expression, to follow the fate of transplanted cells in animal models of Parkinson's disease, and to augment the proliferation of these cells by blocking NOS activity. We further propose to generate a double-transgenic mouse line where neural stem cells and differentiated dopaminergic neurons will be marked by the expression of two different fluorescent proteins. This proposal directly relates to the purpose of this RFA as stated in the guidelines: it proposes a strategy for reversing the pathogenesis of Parkinson's disease and it proposes developing an animal model for the studies of the disease.

Project Title: ASSESSMENT OF DISEASE PROGRESSION IN PARKINSONISM Principal Investigator & Institution: Eidelberg, David; Director, Center for Neurosciences; North Shore University Hospital 300 Community Dr Manhasset, Ny 11030 Timing: Fiscal Year 2001; Project Start 06-APR-1999; Project End 31-MAR-2004 Summary: The proposed Midcareer Investigator Award is designed to provide the candidate with salary support to devote more time to patient- oriented research and to facilitate his role in mentoring beginning clinical investigators in the field of functional brain imaging in neurodegenerative disorders. Research plan: Parkinson's disease (PD) is the most common degenerative hypokinetic movement disorder. Great strides have been made in the understanding of the pathophysiological mechanisms underlying the neurodegenerative processes in PD, prompting clinical trials of new therapies aimed at slowing or halting the progression of these diseases. To assess these new therapies, reliable in vivo markers of neuronal loss are needed. Currently available clinical measures of disease progression are relatively insensitive, and may not accurately reflect the extent of neuropathological change. Alternatively, quantitative biologically relevant brain imaging markers now exist which may be suitable as outcome measures for clinical trials. Specifically, we have developed three novel methods of assessing disease progression using positron emission tomography (PET): (1) The quantification of dopaminergic function using a radioligand which binds selectively to the dopamine transporter (DAT); (2) The quantification of metabolic brain networks in the resting state; and (3) The quantification of dynamic changes in brain-behavior relationships using regional blood flow activation and network analysis. The goal of the proposed project is to assess the extent to which neurochemical and functional PET imaging markers are sensitive to change in early stage PD, and to compare these measures to standard clinical indices of disease progression. To this end, we propose a longitudinal five-year study to assess disease progression using neurochemical, metabolic, and functional activation PET markers. We hypothesize that PET measures will be more sensitive to disease progression than clinical measures. If this is the case, clinical trials designed to assess potential neuroprotective therapies could require fewer patients and

be completed in less time. Mentoring plan: The candidate will recruit promising young physicians who have completed high level clinical training in neurology and ancillary specialties. He will afford these individuals with a stimulating post-graduate experience involving specialized aspects of patient-oriented research in movement disorders. He will also provide structured training in the fundamentals of experimental neurological research in using new functional brain imaging techniques.

Project Title: CATECHOL THIOETHERS IN PARKINSON'S DISEASE Principal Investigator & Institution: Montine, Thomas J.; Professor; Pathology; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2005 Summary: (adapted from applicant's abstract) Parkinson's disease (PD) is a serious public health problem for the United States. Although dramatic advances have been made in the clinical management of Parkinson's disease, understanding of the mechanisms that underlie its neurodegeneration is incomplete. Such knowledge will be necessary for future development of therapeutics that impede or halt the progression of Parkinson's disease. The long-term objectives of this project are to determine the mechanisms by which oxidation products of dopamine and related catechols, catechol thioethers, may be converted to neurotoxins that contribute to nigrostriatal oxidative damage and neurodegeneration. The Specific Aims of this projects are: (1) to determine the potency of endogenous catechol thioether produced in the mercapturic acid pathway and the mechanisms by which they may contribute to dopaminergic neurodegeneration in whole mitochondria, cultured dopaminergic neurons, brain regions of aged control and genetically engineered mice with deficiencies in anti-oxidant defenses, (2) to determine the activities of mercapturic acid pathway enzymes and the concentration of catechol mercapturates in brain regions and CSF from patients with Parkinson's disease, other nigrostriatal neurodegenerative diseases, and aged-matched controls, and (3) to determine the mechanisms by which environmental toxicants epidemiological linked with an increased risk of Parkinson's disease may augment neurotoxicity form catechol thioethers. This new information will determine the extent to which catechol thioethers produced in the mercapturic acid pathway may contribute to Parkinson's disease progression, interact with aging and environmental toxicants implicated in Parkinson's disease, and serve as intra vitam biomarkers of nigrostriatal degeneration.

Project Title: CLINICAL CENTER FOR NEUROPROTECTION IN PARKINSON DISEASE Principal Investigator & Institution: Dewey, Richard B.; Neurology; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2002; Project Start 15-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Parkinson's disease is an inexorably progressive disorder of unknown cause in which neurons of the substantial nigra progressively degenerate resulting in ever-greater degrees of brain dopamine deficiency. While a number of treatments have been developed that improve the neurochemical deficit, no treatment has been demonstrated to ameliorate the neuronal deterioration. Such a neuroprotective effect is highly desirable because if this could be achieved, a significant delay in clinical deterioration of patients could be realized. The proposal outlined here

aims to establish a Clinical Center for neuroprotective research at UT Southwestern Medical Center which will cooperate with up to 42 other such centers around the country in the development and execution of a large-scale clinical trial to test one or more potentially neuroprotective agents for Parkinson's disease. The Clinical Center for Movement Disorders at UT Southwestern Medical Center in Dallas, TX is well suited to becoming such a Clinical Center. It is the primary academic referral center for North Texas and its two staff neurologists are experienced in the design, conduct, and reporting of clinical trials in Parkinson's disease. Once the Clinical Centers are designated, a series of pilot studies will be conducted first to identify the most promising agent or agents. Subsequently, a large trial involving several thousand patients will be developed and conducted to establish whether the chosen agent is actually capable of slowing down the progression of this disease. By studying such a large number of patients under rigorously blinded and controlled conditions, it should be possible to identify even a small beneficial effect on disease progression which would nevertheless be very important, not only for the implications on retarding disease progression, but also because observing such an effect might yield insights into the underlying pathogenesis of this common and disabling disease.

Project Title: CLINICAL CENTER FOR THE STUDY OF NEUROPROTECTION FROM PD Principal Investigator & Institution: Tintner, Ron; Neurology; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Our objective is to participate as a clinical center in a national multi-center trial of neuroprotective agents in Parkinson's disease (PD). Over the course of the next five years, we plan to enroll at least two patients per month into these clinical trials to evaluate the efficacy of (yet to be determined) agents for neuroprotection of patients with Parkinson's disease. These patients will be recruited from the Parkinson's Disease Center and Movement Disorders Clinic at Baylor College of Medicine; movement disorders clinic at Ben Taub General Hospital; and, with recruiting efforts in conjunction with local Parkinson's disease support groups. These patients will be evaluated in depth to ensure they meet the criteria for the studies, carefully evaluated with agreed-upon clinical measures and medically monitored to ensure their safety and well-being during the course of the study. We will perform as much of the evaluation as possible at our campus in the Texas Medical Center, but will cooperate fully and enthusiastically to enable evaluations done at cooperating institutions. We will lend our expertise, experience and time to help develop these clinical protocols. We will record complete and accurate data as agreed upon in the study protocols and ensure timely transmission to the statistical coordinating center. We will participate and cooperate with other members and institutions in data analysis and writing and communicating the results of these trials.

Parkinson’s Disease

Summary: (provided by applicant): The objective of this project is to perform pilot studies to identify putative neuroprotective agents for Parkinson's disease and to demonstrate convincingly in a randomized, double-blind clinical trial the efficacy of one or more pharmacological agents for slowing the progression of Parkinson's disease and to determine the toxicity and tolerability of these agents.Our Clinical Research Center will be a consortium of three local sites, each with a history and interest in conducting Parkinson's disease clinical trials. The lead site will be Thomas Jefferson University (Parkinson's Disease Research Unit), with satellite sites at Main Line Health Hospitals in Bryn Mawr, PA and Neurology Associates, P.A. in Wilmington, DE. This consortium, spanning the Philadelphia metropolitan area, the heavily populated northwestern suburbs of Philadelphia, Southeast Pennsylvania, Southern New Jersey and the entire state of Delaware will greatly enhance our ability to enroll patients in any research project in which we participate. The strength of this consortium is the collective research expertise of the participants and the resultant enhanced availability of early Parkinson's disease patients. As a result of this consortium, we are confident that we will be able to exceed the minimum number of patients to be recruited into study by approximately 50%. Each component of this Clinical Center is staffed by clinical personnel experienced in the clinical and research assessment of Parkinson's disease patients and by accomplished nurses and clinical coordinators with experience in the recruitment and retention of Parkinson's disease patients and the administration of clinical protocols.

Project Title: DEEP BRAIN STIMULATION IN PARKINSON'S MODELS Principal Investigator & Institution: Anderson, Marjorie E.; Professor; Rehabilitation Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-MAY-2007 Summary: (provided by applicant): Although high-frequency deep brain stimulation (HF-DBS) in the globus pallidus or subthalamic nucleus has become a common technique used to treat drug-resistant symptoms of Parkinson's disease, the mechanisms by which HF-DBS exerts its effects are unknown. In the proposed studies, the ability of chronic administration of the insecticide rotenone, to produce an animal model of Parkinson's disease will first be tested in monkeys. Using PET imaging now available in the University of Washington Regional Primate Research Center, changes in dopamine innervation after administration of rotenone will be measured using a marker of the monoamine vescicular transporter that is present in dopaminergic nerve terminals. These changes will then be correlated, over time, with changes in behavior and with electrophysiological changes in the rate and pattern of discharge of neurons in basal ganglia-receiving areas of the thalamus. This model will then be used to couple the electrophysiological effects of HF-DBS, which can be recorded from basal gangliareceiving neurons of the thalamus, to the stimulation-induced changes in regional metabolism in the cortex and thalamus. PET imaging with the metabolic marker, [8-F] flurodeoxyglucose (FDG), will be used to measure metabolism. This technique has generally shown a relative hypermetabolism in the globus pallidus and thalamus of humans with Parkinson's disease and a relative hypometabolism in areas of the frontal cortex. Changes reported to be induced by HF-DBS have been mixed however. The combination of electrophysiology and metabolic imaging will allow us to address some of the discrepancies from the human literature. Special attention will be paid to the development of abnormal patterns of bursting behavior in the thalamus of monkeys treated with rotenone, as well as the effect of HF-DBS on burst behavior. This will test the hypothesis that some of the symptomatology of Parkinson's disease, and its relief

using HF-DBS, is a consequence of abnormal patterns of activity in basal gangliathalamic-cortical circuits. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: DEMENTIA OF PARKINSON TYPE: CLINICOPATHOLOGIC PHENOTYPE Principal Investigator & Institution: Galvin, James E.; Assistant Professor; Neurology; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2005 Summary: Parkinson's disease and Dementia with Lewy bodies (DLB) together comprise the second most common form of dementia after Alzheimer's Disease (AD). The signature pathologic lesions in these disorders are Lewy bodies (Lbs) found in cortical (DLB) and nigral (PD) neurons. Furthermore, a significant number of AD patients develop parkinsonian signs during the course of disease and many of these patients also are found to have Lbs on autopsy. Whether previously diagnosed with PDassociated dementia now would be classified as DLB is unknown. It is also unclear that PD alone can cause dementia occurs only in the presence of critical Lbs or AD-related pathology. The goal of this project is to characterize the clinicopathologic phenotypes of Dementia of the Parkinson Type (DPT). We propose to analyze the longitudinal studies of the Alzheimer's Disease Research Center (ADRC) for the clinical, motor, cognitive, behavioral, and pathologic characteristics of autopsy defined case of AD, PD and DLB in order to: 1) determine those clinical features that differentiate pathologically diagnosed DLB and PD from AD and from each other to establish the DPT phenotype; 2) identify differences between groups in pathologic features other than those used in the diagnosis by exploring the neuroanatomical correlates of the unique clinical symptomatology of DPT; and 3) to determine the best short set of clinical features for the diagnosis of pathologically defined DPT groups. The ADRC and the Department of Neurology at Washington University School of Medicine provide the candidate with an outstanding environment to develop his skills as an independent clinician-scientist. This K08 award will make available to the candidate protected time to complete the Specific Aims of the project and complete didactic courses in the ethical conduct of research, biostatistics and epidemiological study design. The research career development plan of the candidate is to use the mentored period to establish in the field of dementia research, specifically examining the role co-existent pathologies play in the onset, progression and unique characteristics of dementing disorders. At the completion of the award period, candidate plans to develop an independent R01 project derived from the data generated by the experiments described in this proposal.

Project Title: DEVELOPMENT OF AN IMAGING MARKER FOR PARKINSON'S DISEASE Principal Investigator & Institution: Jennings, Danna L.; Molecular Neuroimaging, Llc 60 Temple St, Ste 8A New Haven, Ct 06510 Timing: Fiscal Year 2002; Project Start 15-JUN-2002; Project End 31-DEC-2002 Summary: (provided by applicant): The development of disease modifying agents in Parkinson's disease has rapidly expanded the need for in vivo markers for diagnosis and monitoring disease progression. Dopamine transporter (DAT) imaging offers the promise of an objective measure of dopaminergic degeneration allowing for identification of changes in the brain that occur early in the illness, prior to clinical

Parkinson’s Disease

diagnosis. The primary goal of this project is to examine the sensitivity and specificity of DAT imaging using (3-CIT and SPECT imaging as a diagnostic marker in subjects with suspected PD or PS. Neurologists will identify subjects in whom they have genuine uncertainty regarding diagnosis of PD or PS. The neurologists will be asked to document their 'best guess' diagnosis on a Diagnostic Accuracy Questionnaire at the time of referral. Subjects with suspected PD or PS will be evaluated clinically and with DAT imaging at MNI. The blinded Parkinson's expert will re-examine the subject in 6 months and make a final clinical diagnosis, which will serve as the gold standard diagnosis for each subject. The DAT imaging diagnosis will be compared to the 'gold standard' clinical diagnosis to determine the sensitivity of (3-CIT and SPECT imaging as a diagnostic marker in PD and PS. This project is a crucial step to begin to establish BCIT and SPECT imaging as an objective diagnostic biomarker prior to definitive diagnosis.

Project Title: DEVELOPMENT OF INTEGRATING HSV AMPLICONS FOR PARKINSON'S DISEASE Principal Investigator & Institution: Bowers, William J.; University of Rochester Orpa Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: Gene transfer methodologies have created the opportunity for developing gene therapy for human neurological diseases such as Parkinson's Disease (PD). Adeno-associated virus (AAV) and lentivirus vectors, both of which integrate into the host cell chromosome, have been shown to provide long-term expression of genes and therapeutic efficacy in animal models of PD. These vectors, however, exhibit a number of disadvantages, among them an inability to harbor large transgene segments. Gene therapy vectors based upon the Herpes Simplex virus (HSV) offer numerous advantages for the development of novel therapeutics for PD. These include broad cellular tropism, large DNA packaging capacity that allows for expression of multiple genes, and high transduction efficiency. We propose to modify HSV-derived amplicon vectors to provide stable nigrostriatal cell-specific gene expression. For this pipeline project, we will initially construct novel integrating forms of the amplicon that will direct expression of a reporter gene product specifically within cells of the striatum and substantia nigra. DNA insulator elements will be introduced to facilitate maintenance of the integrated transcription unit in a euchromatic state. These new vectors will be coadministered with an amplicon expressing the Sleeping Beauty transposase into the striata of unlesioned rats, where gene expression duration and cell-type specificity will be experimentally derived. The vectors will then be used to deliver glial cell line-derived neurotrophic factor (GDNF) prior to 6-OHDA-induced lesioning of rats to assess the capacity of the new vector system to confer protection to the nigrostriatal pathway. The proposed studies will yield a novel HSV vector system, provide a detailed understanding of transgene expression in vivo, and evaluate its therapeutic effectiveness in protecting nigrostriatal neurons in a well-established rodent model of PD.

Timing: Fiscal Year 2001; Project Start 01-APR-1997; Project End 31-MAR-2002 Summary: We propose to document the occurrence of multiple sclerosis (MS) and Parkinson's disease (PD) among male and female participants of three large ongoing prospective studies and to examine prospectively the association between several dietary and non-dietary risk factors and the incidence of these diseases. The studies are the Nurses' Health Study I (121,000 women), Nurses' Health Study II (116,000 women), and the Health Professionals Follow-up Study (52,000 men). Diet has been assessed repeatedly by a semiquantitative food frequency questinnaire developed and refined by our group over the last 15 years; detailed studies in subsamples of participants demonstrate that this questionnaire performs well, and that the study populations have substantial various in dietary intakes. Several follow-up cycles have been completed, with responses over 90 percent. Numerous non-dietary variables of potential interest as risk factors for MS and Parkinson's disease or as potential confounders of the associations between diet and these diseases have also already been collected at baseline and during the follow-up. We will evaluate the association between history of childhood infections or exposure to dogs potentially infected with the cannine distemper virus and risk of multiple sclerosis by conducting a nested case-control study. In addition, we will examine the association between selected mutations of CYP-2D6-one of the cytochrome P450 enzymes-and risk of PD, and the potential interaction between CPY-2D6 mutations and cigarette smoking as risk factors for PD. The CYP-2D6 genotype will be determined using blood samples that have already been collected, or buccal smears that will be obtained as part of this grant from cases of PD for whom on blood samples are available. The proposed investigation is a highly cost-effective way for studying diet and MS and PD because it draws on a large amount of information already collected and processed, and because the cost of mailing and processing of the foollow-up questionnaires is provided by other sources (CA 55075, CA 40356, CA 50385). Reported cases of MS and PD will be confirmed by supplementary questionnaires sent to the patients and their physicians. Fatal events are identified by next-of-kin, postal service, or the National Death Index and confirmed by hospital records and other additional information. By the end of the follow-up, we project a total of 461 confirmed cases of MS and 380 confirmed cases of PD. We will have sufficient poser to evaluate a series of specific hypotheses with substantial public health implications. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: DISABILITY IN PARKINSON'S DISEASE Principal Investigator & Institution: Bassett, Susan S.; Associate Professor; Psychiatry and Behavioral Scis; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 07-SEP-2001; Project End 31-JUL-2006 Summary: Disability affects as much as 17 percent of the adult population in the US and the majority of these individuals suffer both chronic medical conditions and psychiatric disorders. In combination, the impairments that accompany these disorders synergistically intensify any disability. Parkinson's disease (PD), a progressive neurodegenerative disorder, produces marked impairments of motor function and significant disability. However, the majority of PD patients also experience emotional and cognitive impairments, yet little is known about the contribution of these impairments to disability. In addition, disability assessment in PD has focused narrowly on self-care, ignoring other important areas such as work performance. It is unknown, for example, whether withdrawal from the workforce among PD patients is more closely tied to emotional and cognitive impairments than to decrements in motor function. The aim of this project is to assess impairments in motor, cognitive and

16

Parkinson’s Disease

emotional function and the accompanying disabilities, longitudinally, in individuals with PD, to understand how the impairments contribute to disability and how psychiatric disorders produce excess disability in these patients. Specifically we will examine performance on quantitative motor tests and cognitive tests of memory, attention and executive function. Psychiatric symptom occurrence and severity, clinical diagnosis, and temperament will also be examined. Disability assessment will include the areas of physical, social and occupational functioning as well as perceived quality of life, utilizing clinical interview, performance evaluation, vocational testing and informant interview. Participants will include 100 non-demented individuals with PD, 65 years of age or younger. Approximately equal numbers of males and females will be enrolled. All participants will be evaluated yearly, four times during the course of the project. Investigation into the full range of disability found in PD, and an understanding of the contribution all impairments play in increasing disability, will enable us to develop strategies to improve the care of these patients. It will also provide information to guide interventions to decrease the level of disability suffered by those with PD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: DOPAMINE AND OXIDATIVE STRESS IN PARKINSON'S DISEASE. Principal Investigator & Institution: Sidhu, Anita; Associate Professor; Pediatrics; Georgetown University Washington, Dc 20057 Timing: Fiscal Year 2002; Project Start 30-SEP-1995; Project End 31-MAR-2007 Summary: (provided by applicant): Oxidative stress is an important causative factor in the onset and maintenance of several neurodegenerative conditions, such as Alzheimer's disease and Parkinson's Disease (PD). While dopamine (DA)-replacement therapy can control the symptoms of PD, it can also cause severe dyskinesia in patients. Blockage of the D1 DA receptors with Dl-selective antagonists in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-lesioned primates, significantly improves dyskinesia, through unknown mechanisms. Autoxidation of DA is a major source of free radicals; activation of D1 receptors also triggers oxidative stress, and these effects are additive, such that the resulting damage produced in the postsynaptic cell is several fold greater than that elicited by sources of free radicals (hydrogen peroxide (H202)), which does not stimulate the D1 receptor. Several indices of oxidative stress, lipid peroxidation, nitrite production, nitric oxide synthases, neurofilament (NF)-kappaB nuclear translocation, are all elevated two to six fold higher with DA-mediated D1 receptor activation, than H202 alone. We will examine in detail the contribution of D1 receptor stimulation, through the use of agonists and antagonists, in causing oxidative stress in SK-N-MC human neuroblastoma cells, which endogenously express the D1 receptor and is representative of postsynaptic cells. We will examine the mechanism and functional consequences of D1 receptor stimulation on signaling pathways, as well as by selectively blocking parts of the oxidative stress cascade(s). The participation of D1 receptors and oxidative stress in cell death and apoptosis will also be measured. Since blockage of D1 receptors in the MPTP model of PD improves some of the symptoms of PD, we will investigate whether D1 receptors augment MPTP effects in SK-N-MC cells. Conversely, blockage of D1 receptors with antagonists may attenuate MPTP effects on the various indices of oxidative stress. A clear understanding of the effects of dopamine autoxidation and the participation of D1 DA receptors in inducing oxidative stress, is important for understanding patient response to agonist therapy in PD, and may aid in the design of novel therapeutic treatments.

Project Title: ECONOMIC AND POLICY ANALYSES IN GERIATRIC DISEASE Principal Investigator & Institution: Noyes, Ekaterina I.; Community and Prev Medicine; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Dr. Noyes proposes to develop the skills necessary to become an independent researcher in the field of cost-effectiveness analysis and health policy evaluation in geriatric disease. The candidate's undergraduate training in biomedical physics and PhD training in neurophysiology confirm her commitment to research as well as her strong analytical capabilities. To strengthen her knowledge in health care policy, outcomes evaluation, statistical analysis, and data management, the candidate will complete the proposed didactic coursework and participate in a series of clinical skills workshops and seminars. The candidate will spend the main part of the five-year grant period conducting proposed research. The candidate's long-term plan is to improve efficiency of the health care system by incorporating cost-effectiveness analysis into health care policy and decision making, in particular, related to Parkinson's disease (PD) and geriatric depression. The study will address shortcomings of the methods currently used to evaluate outcomes in PD and will use patient's quality of life as the effectiveness measure. It is hypothesized that 1) levodopa is more cost-effective than pramipexole in the treatment of early PD; 2) elderly chronically ill patients use more health services than do general Medicare beneficiaries; and 3) disability and long-term care are the main sources of expenses associated with chronic geriatric disease. The project's specific aims are to conduct a cost-effectiveness analysis of early PD therapy with pramipexole compared to levodopa, to assess the pattern of health care utilization in Medicare beneficiaries with PD, and to develop a Parkinson's disease health policy pilot model. The cost-effectiveness will be assessed based on 4 years of data collected from a clinical-economic trial in PD. The patterns of health services utilization of Medicare patients will de examined using the Medicare Current Beneficiary Survey. Supplemental data on costs will be collected from published literature and Medicare fee schedules. The study design will include costeffectiveness analysis, decision analytical modeling, sensitivity analysis, and Bayesian statistics. The results of this study can serve as a foundation for developing clinical guidelines for PD, provide information for resource allocation with respect to long term institutional and informal care, and to improve public health policy associated with chronic diseases and aging. Supervision for this project will be provided by a multidisciplinary team at the University of Rochester whose members are experienced in fostering the development of clinical researchers. The model and analytical approaches acquired by the candidate during her training will be used later to develop a decision analytical model describing geriatric depression.

Project Title: EFFECTS OF STRESS ON PATHOLOGY OF PARKINSON'S DISEASE Principal Investigator & Institution: Metz, Gerlinde A.; University of Lethbridge 4401 University Dr Lethbridge, Timing: Fiscal Year 2003; Project Start 15-JUN-2003; Project End 31-MAY-2005 Summary: (provided by applicant): Stress can have beneficial and maladaptive consequences depending on its type and duration. Stress can affect motor function and the course of neurodegenerative diseases of the motor system, however, this relationship has not been characterized yet. The proposed projects focus on a systematic investigation of the effects of stress and glucocorticoids, the major stress hormones, on

18

Parkinson’s Disease

motor function and neurodegeneration in Parkinson's disease (PD). The research proposal has three objectives: 1) Do stress and glucocorticoids affect motor performance? This objective is to characterize how stress or glucocorticoids affect skilled and locomotor movements. Glucocorticoid levels of rats will be manipulated and dosedependent effects determined. It is expected that high levels of stress or glucocorticoids alter motor performance more likely than lower doses and that skilled movement are more susceptible to stress than locomotion. 2) Do glucocorticoids affect the onset and course of PD? This objective is to investigate the role of glucocorticoids in motor function and neurodegeneration in three rat models for PD, an acute and a progressive neurotoxic lesion, and a slow progressive lesion induced by an environmental toxin, used as a pesticide. Glucocorticoid levels will be manipulated and functional abilities assessed accordingly. It is expected that absence of glucocorticoids or chronically elevated levels lead to detrimental effects in the course of PD. 3) Can drug treatments or experience attenuate glucocorticoid-induced behavioral and histological aggravation in PD? This objective is to examine possible therapeutic interventions to protect the motor system and its function from harmful effects induced by elevated glucocorticoid levels. One series of experiments will investigate a pharmacological approach, which reduces glucocorticoid levels. Another series of experiments will assess the influence of environmental enrichment on the pathology of Parkinson's disease. It is expected that both treatments slow the progression of neural degeneration and diminish severity of motor symptoms. These projects will determine (1) the degree to which stress and glucocorticoids can influence motor learning, performance, and anatomy of the motor system, (2) the role of glucocortcoids in the etiology of PD and the progression of neural death and motor symptoms, and (3) which interventions can alter the influence of glucocorticoids on the course of PD. These approaches will provide the opportunity to understand factors involved in the pathology of PD and to develop novel therapeutic strategies for neurodegenerative motor disorders.

Project Title: ENVIRONMENTAL AND GENETIC RISKS FOR PARKINSON'S DISEASE Principal Investigator & Institution: Nelson, Lorene M.; Associate Professor; Health Research and Policy; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2001; Project Start 01-JUN-1994; Project End 31-JUL-2005 Summary: The primary goal of this project is to investigate whether certain environmental exposures and genetic variants, either alone or in combination, affect the risk of developing Parkinson's disease (PD). We will investigate mechanisms that may explain the consistently observed inverse associations of cigarette smoking and caffeine consumption with PD, and the role of residential pesticide exposure on the risk of PD. In addition, existing and newly-identified polymorphisms in the coding and regulatory regions of candidate genes will be investigated, including genes that code for: (1) endogenous enzymes involved in metabolism of tobacco or caffeine, or in the detoxification of putative toxicants for PD, (2) proteins involved in dopamine regulation or metabolism, and (3) proteins that play a role in protein degradation and aggregation in dopaminergic neurons. We propose to expand a recently completed case-control study in a large health maintenance population of more than 500 newly diagnosed PD cases and 500 controls. Because preliminary data show that the strongest associations of genetic variants were observed among PD cases with early age at diagnosis (age less than or equal to 60), we will identify approximately 330 additional such cases along with age- and sex-matched controls. This new sample will be combined with that of the previous study, resulting in approximately 420 young diagnosis cases and 430 older diagnosis (age greater than 60) cases to be compared with 870 age- and gender-matched controls. Detailed information will be collected from all study subjects using in- person and telephone structured interviews including information on cigarette smoking, caffeine intake, and residential exposure to pesticides, along with other putative risk factors. Venous blood samples will be drawn for DNA extraction and genotyping assays for the gene polymorphisms of interest. By examining genetic polymorphisms within a group of carefully chosen candidate genes, in combination with extensive information about common environmental exposures, we hope to advance knowledge regarding both genetic and modifiable environmental risk factors for Parkinson's disease.

Parkinson’s Disease

Summary: The long-term goal of our research is to identify the cause(s) of Parkinson's disease. This proposal features an integrative approach to the investigation of (1) cellular mechanisms involved in neurodegeneration, (2) environmental determinants that affect disease risk, and (3) genetic factors that may affect susceptibility. It is composed of four different integrative research projects, and three cores (administrative, research development, and information outreach), which together make up a Coordinated Center for Parkinson's Disease Environment Research. The broad theme underlying this proposal is that Parkinson's disease results from the interaction between environmental toxicants (such as pesticides or metals), protective factors in the environment (such as nicotine, caffeine) and genetic susceptibility factors. Project 1 (entitled "Genes, Environment & PD: Studies in 4 Unique Cohorts") investigates the separate and combined roles of occupational toxicant exposure (pesticides, metals), genetic variants of membrane transporters of these toxicants and putative neuroprotective behaviors (tobacco & caffeine use) in more than 1000 PD cases and over 1500 controls. Shared diagnostic and exposure assessment in 4 cohorts facilitates combined analyses, while the diverse characteristics of each cohort maximize generalizability. The goal of Project 2 (entitled "Neurotoxicants, Oxidative Stress and Alpha-synuclein") is to investigate the role of oxidative stress as a key contributor to the development of alpha-synuclein aggregation, inclusion body formation and ultimately neuronal injury at the experimental level. The effects of metals/pesticides on these pathological processes will also be assessed. Our third project (entitled "Iron, Oxidative Stress, and Pesticides)," will examine (i) the agerelated susceptibility of the mouse nigrostriatal system to combined damage from iron and pesticide exposure, (ii) the effects of oxidative stress in the context of such exposures, and (iii) ways to protect against these effects. Both Projects 2 and 3 will utilize well-established and novel transgenic models to achieve their scientific goals. Our fourth project (entitled," Nicotine and neuroprotection in nonhuman primates") will explore the effects of nicotine as a potential neuroprotective agent against nigrostriatal injury in a primate model of Parkinson's disease. The hypothesis that this action may be achieved through a receptor mediated stimulation of growth factors will also be examined. These integrative research projects should provide important new insights in the environmental, genetic and cellular factors contributing to Parkinson's disease, and could bring us closer to finding the cause of the disease. Success in these endeavors could lead to new strategies for treatment and even disease prevention. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: EPIDEMIOLOGY AND GENETICS OF PARKINSON'S DISEASE Principal Investigator & Institution: Rocca, Walter A.; Professor of Epidemiology and Neurology; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2001; Project Start 01-JUN-1996; Project End 31-MAY-2006 Summary: (Adapted from applicant's abstract): Parkinson's disease (PD) is a common and disabling condition in the expanding elderly population of the US and worldwide. Its etiology remains unknown and both genetic and environmental factors have been suspected. The long-term goal of the proposed studies based in different sampling is to clarify the etiology of PD and to identify means to prevent it. Three independent but related studies based on different sampling and measurement strategies are proposed. The hypotheses tested derive directly from our current work and preliminary findings. A case control study will include 800 cases of PD referred to the Mayo clinic from a 120 mile radius or from a 5 state region and 800 controls free pf PD and parkinsonism matched by age (+ 2 years), sex and region of residence. Controls from the general

population will be identified from health care financial administration lists for cases aged 65 years or above and through random digit dialing for cases below 65 years. Exposures will be accessed through direct telephone interview, and will include tobacco, coffee, and alcohol use; markers of novelty seeking behavior; and, for women, use of estrogen replacement therapy after menopause and other reproductive and estrogen related factors. A first historical cohort study will test the association between unilateral and bilateral oophorectomy before menopause and PD in an established population based cohort. The study will include 2,533 women who underwent oophorectomy in 1950-1987 while residing in Olmsted County, MN and 2,533 women of the same age and residence who did not undergo oophorectomy. A second historical study will test the association between personality traits measured by the Minnesota Multiphasic Personality Inventory (MMPI) and PD in an established research cohort. This study will include 8,775 persons who underwent MMPI testing in 1962-1965 while residing in Minnesota. The proposed case-control study is strong because it has adequate statistical power to confirm our preliminary findings on the role of estrogen in PD and to explore the link between substance use and novelty seeking behaviors in PD. All interviews with case and controls will be direct, the proposed oophorectomy cohort study is strong because of its cohort design, its population-based sampling, its adequate statistical power, and because of the expected high rate of follow-up through both passive and active strategies. The proposed MMPI cohort study is strong because of its cohort design, its adequate statistical power and because of our extensive experience with tracing and interviewing individuals. These three studies will contribute greatly to understanding the causes and possible prevention of PD by exploring novel hypotheses and by using innovative methods.

Project Title: EPIDEMIOLOGY, PATHOLOGY, AND PARKINSONISM IN AGING Principal Investigator & Institution: Schneider, Julie A.; Rush-Presbyterian-St Lukes Medical Ctr Chicago, Il 60612 Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2005 Summary: This 5-year clinical scientist development award proposes the use of quantitative epidemiologic principles to relate post-mortem findings to neurologic conditions associated with aging. A spectrum of parkinsonian signs, including bradykinesia, rigidity, tremor, and gait imbalance are common in older persons without Parkinson's disease, and are associated with increased morbidity and mortality. The nigrostriatal system also shows a spectrum of change with age. Preliminary data suggest that nigral neurofibrillary pathology is more common than previously recognized and is related to parkinsonian signs in older persons with and without Alzheimer's disease. The proposed studies will relate nigral neurofibrillary pathology and biochemical nigrostriatal changes to quantitative measures of global and specific parkinsonian signs in older persons with and without Alzheimer's disease. We will test the hypotheses that neurofibrillary pathology, specifically within the pars compacta of the substantia nigra, rather than the ventral tegmental or retrorubral areas, accounts for parkinsonian signs in older persons with and without AD, and that the mechanism by which neurofibrillary pathology produces parkinsonian signs involves decreased gene expression of tyrosine hydroxylase and a reduction in striatal dopamine, but not neuronal loss. We will also determine the role of mitochondrial mutations in the pathogenesis of neurofibrillary pathology and parkinsonian signs. The proposed project will use brain tissue of 80 older persons, without Parkinson's disease, in The Religious Order Study, a longitudinal study of over 650 catholic clergy who have agreed to annual examinations and brain

The proposed study will provide the Candidate in the opportunity to work with senior colleagues and allow the development of a unique research area that integrates the clinical neurology and neuropathology training. Through the course of these studies and analyses, through didactic sessions with her sponsors and consultants, and related course work, the candidate will develop the skills necessary to become an independent investigator.

Project Title: EVALUATION OF DOPAMINE RECEPTORS FOR PARKINSON'S DISEASE Principal Investigator & Institution: Kopin, Alan S.; New England Medical Center Hospitals 750 Washington St Boston, Ma 021111533 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2004 Summary: (provided by applicant): Parkinson's disease (PD) results from the degeneration of nigrostriatal dopaminergic neurons. This process ultimately leads to a progressive decrease in dopamine mediated striatal signaling which manifests as a clinical syndrome characterized by bradykinesia, rigidity, tremor, and gait abnormalities. Traditional therapy for PD has aimed at restoring dopamine levels in the striatum through administration of the dopamine precursor, L-dopa. With advanced disease, L-dopa leads to dyskinesias and periods of marked fluctuation in motor activity ('on-off effect'). Alleviation of these side effects has been a major challenge and has prompted a search for alternative strategies which can provide a more stable level of dopaminergic signaling. A previously unexplored option to restore striatal dopaminergic activity and at the same time to potentially avoid the consequences of long term L-dopa administration, is through the introduction of constitutively active dopamine receptors. The laboratory of the PI has extensive experience in generating receptors with ligand independent (or constitutive) activity through the introduction of activating point mutations. These receptors have the potential to maintain dopaminergic signaling even in the absence of dopamine and/or dopaminergic agonist drugs. The premise of this application is that constitutively active dopamine receptors can be identified using in vitro assays and expressed in the striatum of rats to enhance dopaminergic signaling over an extended time interval. The objective of Specific Aim 1 is to generate and pharmacologically characterize in vitro a series of constitutively active dopamine 1 and dopamine 2 receptors. Using recombinant adeno-associated virus, the functional consequences of striatal overexpression of constitutively active dopamine receptors will be explored in rats (Specific Aim 2). Circling behavior after unilateral viral administration will be used as an index of construct activity. The methodologies utilized will include molecular (generation of constitutively active mutant receptors, expression of recombinant proteins), pharmacologic (radioligand binding, second messenger signaling assays), and behavioral approaches (assessment of circling behavior). These experiments will provide additional insight into the role of dopaminergic receptors in the striatum as well as potentially take the first steps toward the development of a new therapeutic option for Parkinson's disease.

Timing: Fiscal Year 2003; Project Start 11-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): Impairments of spinal and extremity range of motion occur as sequelae to Parkinson's disease (PD) and contribute significantly to difficulties with balance. While subtle impairments of balance may not be obvious on routine clinical examination, they clearly are present early in the disease when appropriately evaluated. If diagnosed early in the disease process, impairments of balance can be remediated with exercise, delaying functional limitations. Coupled with functional retraining, exercise may improve overall physical functional ability and quality of life. Additionally, patients with mild PD have been found to have poor economy of movement during walking. Improvements of economy of movement have not been evaluated with exercise; it is likely that improved range of motion and balance will improve economy of movement. This investigation will examine whether: (1) balance, functional abilities and quality of life improve with improvements of spinal range of motion and balance; (2) physical intervention improves economy of movement, (3) general aerobic conditioning improves functional ability; (4) exercise targeting impairments associated with PD (e.g., range of motion and balance) is more effective than general endurance training and both are more effective than 'standard-of-care' treatments; (5) an ongoing home program, following a supervised exercise program, maintains increased spinal range of motion, balance, and functional ability. The proposed study is a randomized clinical trial, with 3 treatment arms and 4 repeated measures (before and after treatment, with follow-up at 10 and16 months). Specifically we will compare usual care based on a booklet provided by the American Parkinson Foundation, general endurance training, and PD specific flexibility and functional training. The primary outcomes (4 and 10 months) are measures of: (1) overall functional ability (Continuous-Scale Physical Functional Performance test; (2) balance, (Functional Reach); and (3) economy of movement (rate of oxygen consumption at a set walking speed, [(O2 consumption]). We postulate that PD-targeted flexibility and functional training will improve physical functional ability, in part, by improving balance & walking economy. Further, we expect the PD-specific targeted intervention to be more effective than general endurance training or 'standard-of-care' at improving overall physical function.

Project Title: FAS (CD95)-INDUCED REGENERATION OF DOPAMINERGIC NEURONS Principal Investigator & Institution: Desbarats, Julie; Mc Gill University James Admin. Bldg., Room 429 Montreal, Pq H3a 2T5 Timing: Fiscal Year 2002; Project Start 15-FEB-2002; Project End 31-JAN-2004 Summary: Parkinson's disease is characterized by the degeneration of dopamineproducing neurons in the substantial nigra of the brain. The resulting loss of dopamine leads to the cardinal symptoms of Parkinson's disease (PD), namely tremor, bradykinesia, postural instability, and rigidity. The disease is relentlessly progressive, ultimately resulting in a state of almost complete disability. Although PD can be slowed by current treatment protocols, it cannot be cured nor prevented at present. We have recently found that stimulating the cell surface molecule (Fas (CD95) on peripheral sensory neurons induces rapid, extensive neurite outgrowth in vitro, and can accelerate functional recovery in vivo after sciatic nerve crush injury. Contrary to the traditional view of Fas as a "death receptor", we propose that Fas engagement may induce regeneration of the dopaminergic neurons. In support of this notion, PD patients have elevated levels of soluble Fas in the substantial nigra. Soluble Fas acts as decoy receptor

24

Parkinson’s Disease

to prevent cell surface Fas from being engaged. Furthermore, mice with reduced Fas expression undergo progressive neural degeneration, and exhibit neurological and cognitive deficits. We propose to investigate the causal relationship between Fas expression and PD through the following specific aims: 1. To determine the physiological effects, and the signaling pathway(s) triggered, by Fas engagement on dopaminergic neurons. 2. To determine whether lack of Fas expression predisposes dopaminergic neurons to degeneration and/or MPTP toxicity (a model for PD). 3. To establish if anti-Fas antibody can stimulate dopaminergic neuron recovery in vivo. To accomplish these aims, we will use three models: tyrosine hydroxylase-positive (TH+) cell lines; in vitro cultures of embryonic mouse ventral mesencephalon cells enriched for TH+ neurons by flow cytometric sorting; and MPTP- induced nigrostriatal degeneration in the mouse as an in vivo model of PD. We will design our experiments to test the novel concept that Fas is able to induce regeneration in CNS neurons. The successful completion of these aims would yield a conceptually novel direction in the study of PD and neurodegenerative diseases in general, and a new target for innovative treatment strategies.

Project Title: FUNCTIONAL MRI EVALUATION OF PARKINSON'S DISEASE Principal Investigator & Institution: Phillips, Micheal D.; Assistant Professor; Radiology; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2001; Project Start 20-APR-2000; Project End 31-MAR-2003 Summary: The objective of this proposal is to develop a broadly available, reliable diagnostic test for early Parkinson's disease (PD) using functional magnetic resonance imaging (fMRI). PD is one of the most common neurodegenerative disorders, affecting over 1 million people in the United States. It causes significant human suffering and has annual cost of approximately 24 billion dollars in health care resources and lost wages. Clinical and research efforts in PD are hampered by the lack of a widely available objective test for this disease. Although PET and SPECT imaging provide the best objective testing currently available, they are limited by lack of widespread availability, high cost, relatively poor resolution and the use of ionizing radiation. Recent advances in fMRI allow for imaging of neuronal activation along the entire brain motor pathway including the brainstem and basal ganglia during the performance of a complex motor task. These techniques have been successfully applied to both normal subjects and PD patients. Normal subjects demonstrate symmetric activation along the entire motor pathway whereas PD patients demonstrate asymmetric activation with decreased neuronal activation along the motor pathway contralateral to their symptomatically more affected side. The degree of asymmetry has been quantitatively studied using a newly developed cluster analysis technique and demonstrates significant differences between normal individuals and early PD patients. The present application seeks to expand and refine these techniques to produce a clinically applicable diagnostic fMRI test for PD. The application is divided into two phases: a development phase (year 1 of the proposal) and trial phase (years 2 and 3 of the proposal). The development phase will study both patients with early PD and normal subjects to address two specific aims: 1) modification of the existing fMRI protocol in order to make it shorter and easier to perform while maintaining the robust activation achieved presently and 2) rigorous quantification of motor task performance to establish minimum performance criteria. The overall goal of the development phase is to produce a well-characterized fMRI protocol that can be applied in the clinical setting to obtain consistent results. The trial

25

phase will test the newly developed fMRI protocol on a group of patients with early PD and normal subjects. The specific aim of the trial phase will be to test the hypothesis that early PD patients can be distinguished from normal subjects by quantitative measurement of asymmetric fMRI motor pathway activation. A widely available, reliable diagnostic fMRI test for early PD would be useful in both the clinical and research settings. Potential future applications include the detection of preclinical disease, monitoring disease progression and differentiation of PD from parkinsonian syndromes. A single test that could address all of these potential applications would represent an effective diagnostic gold standard for PD. The present proposal represents a first step toward the development of such a gold standard. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: GENE THERAPHY FOR PARKINSON'S DISEASE Principal Investigator & Institution: Bohn, Martha C.; Director of the Neurobiology Program; Children's Memorial Hospital (Chicago) Chicago, Il 606143394 Timing: Fiscal Year 2001; Project Start 01-SEP-1996; Project End 31-MAR-2005 Summary: (Verbatim from the Applicant's Abstract) The long-term goal of this project is to develop novel gene therapies for neurodegenerative diseases. In the previous support period, we focused on adenoviral (Ad) vectors to deliver the gene encoding GDNF (glial cell line-derived neurotrophic factor). Ad-GDNF injected into either the substantia nigra or striatum of a progressive degeneration model of Parkinson's disease protected dopaminergic (DA) neurons against cell death induced by the neurotoxin 6-OHDA. AdGDNF injected into the striatum also prevented the acquisition of behaviors and molecular changes that occurred in DA deficient young and aged rats. This proposal focuses on the hypothesis that anti-apoptotic gene delivery will also protect DA neurons in vitro and in vivo and have a synergistic effect with delivery of neurotrophic factor genes. Viral vectors harboring genes that block specific apoptotic death pathways, including XIAP, a dominant-negative caspase-9, bcl-2 and bclxl will be studied for effects on survival and function of DA neurons either alone or in combination with neurotrophic factors, GDNF or neurturin. Genes will be delivered to DA neurons in culture and in rat brain using helper free HSV:AAV hybrid amplicon vectors. These vectors will incorporate bidirectional expression cassettes that drive both the therapeutic gene and the cellular marker gene, green fluorescent protein, to permit specific evaluation of transduced cells. Expression will be controlled using the tetracycline responsive element such that transgene expression is "on" in the presence of tetracycline activator (TA) and in the absence of doxcycline (Dox). Vectors will be made in which TA is driven by a viral promoter of the DA cellular promoter, tyrosine hydroxylase (TH). Effects of the 'therapeutic' genes will be studied using non-neuronal cells, the DA cell line, MN9D, and primary fetal DA neurons treated with the neurotoxins, MPP+ or 6OHDA or other cellular insults. In vivo effects of therapeutic genes will be studied in: 1) rats that have received grafts of fetal DA neurons, and 2) rats that have received a progressive 6-OHDA lesion of the nigrostriatal projection. Reversibility of effects will be studied by administration of Dox. Effects on DA neurons will be evaluated using quantitative morphometric and molecular techniques and behavioral evaluations. This project also aims to continue its evaluation of new generation viral vectors, including E2b deleted Ad, totally gutted Ad, and HSV:AAV amplicon, for stability and levels of expression in the nigrostriatal system. The studies involve collaborations among investigators at Children's Memorial Hospital and Northwestern Univ. Med. School and are relevant to the development of novel therapies for neurodegenerative diseases and injuries to the CNS.

Project Title: GENE THERAPY FOR NEUROLOGICAL DISEASES Principal Investigator & Institution: Lowenstein, Pedro R.; Director and Professor; Cedars-Sinai Medical Center Box 48750, 8700 Beverly Blvd Los Angeles, Ca 90048 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Parkinson's disease (PD) is a chronic neurodegenerative disorder. Although we do not yet understand its cause, there is extensive degeneration of nigro-striatal DA neurons. Powerful neurotrophic factors, which could be used for the treatment of Parkinson's disease, have been described recently. The ultimate goal of this proposal is to develop novel high-capacity adenoviral systems for long term, stable, non-cytotoxic, and non-immunogenic delivery of neuroprotective genes to the brain for both experimental transgene expression in adult animals, and for the future treatment of chronic neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease by gene therapy. Currently used adenoviruses are efficient vectors for gene transfer into the brain. However, their use has been limited by high doses of vectors needed, vector-cytotoxicity, short-term transgene expression, and deleterious effects of anti-adenovirus inflammatory and immune responses. These limitations are due to: (i) low efficiency of transcriptional promoter elements currently used, which directly leads to the need to use higher doses of vectors, and (ii) cytotoxicity and immunogenicity of viral proteins expressed from the genomes of first generation adenoviral vectors. We now wish to initiate the next stage in the design of efficient, safe, long-term expressing vectors for neurological gene therapy. First, high-capacity helper-dependent adenoviral vectors that express no adenoviral genes will be constructed. Second, the amount of protein produced per input virus will be increased by using stronger promoters alone, or combined with enhancer elements. Third, the efficacy of the new vectors will be tested, by expressing selected neuroprotective genes and verify that they are effective in a model of neurodegeneration. The reagents and principles established by this work will be of substantial value to those with interests in the basic and clinical neurosciences, and will lead to the development of novel approaches to the treatment of chronic neurodegenerative diseases. This research will facilitate the development of the tools needed to achieve long-lived, safe, non-cytotoxic transgene expression, and, ultimately, for the treatment of patients suffering from chronic neurodegenerative disorders.

Project Title: GENE THERAPY FOR PARKINSON'S DISEASE Principal Investigator & Institution: Sun, Mei; Medicine; Harvard University (Medical School) Medical School Campus Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): The principal investigator for this proposal, Dr. Mei Sun, is an Instructor at the West Roxbury VA Hospital / Harvard Medical School. The work outlined in this proposal will serve to further the mentored transition of Dr. Sun into gene therapy of aging related neurodegenerative diseases, and from a research associate to an independent academic investigator applying for RO1 level funding. The mentor in this proposal, Dr. Geller is an independent scientist with extensive published experience on neurobiology and gene therapy. A number of scientists and neurologists including Drs. Geller, Goldstein, Maher, Holmes, Cook, and Shiromani will serve as Dr. Sun's advisors. These scientists will provide her both intellectual and technical advice in

27

their fields of expertise, and will oversee Dr. Sun's progress throughout the grant period. In this proposal, we will investigate an improved gene therapy for Parkinson's Disease. Parkinson's Disease (PD) is a neurodegenerative disorder that primarily affects the aging brain, and the symptoms of PD are principally due to degeneration of nigrostriatal neurons. Current treatments center around restoring striatal dopamine levels and are effective initially. But these treatments gradually lose efficacy, and they do not alter the progression of the Disease. Thus, improved treatments for PD should first, restore the function of the nigrostriatal system, and second, alter progression of the Disease by protecting the remaining nigrostriatal neurons. Our laboratory has previously shown that expression of tyrosine hydroxylase (TH) in striatal cells supports long-term biochemical and behavioral correction of a rat model of PD. I have recently shown that co-expression of TH and aromatic amino acid decarboxylase (AADC) supports both biochemical and behavioral correction of the rat model of PD. Many investigators have shown that glial cell line-derived neurotrophic factor (GDNF) can protect nigrostrital neurons in rodent and primate medols of PD. We now propose to systematically develop an improved gene therapy for PD by two complementary treatment strategies. Gene transfer is performed using a helper virus-free Herpes Simplex Virus vector system pioneered in this Laboratory. The first specific aim will improve biochemical and behavioral correction by investigating the preferred combination of genes (TH, GTP cyclohyrolase, AADC, a vesicular monoamine transporter) to support production and release of dopamine. The second specific aim will combine the 'preferred combination of genes to restore striatal dopamine levels with GDNF to protect nigrostriatal neurons. The long-term goal is to develop human gene therapy for PD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: GENETIC LINKAGE STUDY IN PARKINSON'S DISEASE Principal Investigator & Institution: Myers, Richard H.; Professor; Neurology; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 30-SEP-1997; Project End 31-JUL-2007 Summary: (provided by applicant): The cause of idiopathic Parkinson's disease (PD), a debilitating disease that afflicts an estimated 1 percent of persons age 60 or older, remains unknown. In this application, we propose genetic epidemiological studies, genetic linkage studies, and candidate gene studies for PD. In the past four years, we have established a ulti-institutional research program that has collected 300 PD affected sibling pairs and extended families. Our linkage analyses to onset age revealed evidence for linkage (LOD 2.1) to chromosome 2pl3 at the 'PARK3' locus (Gasser et al. 1998). Recently, we found association (p85% when transfected in human embryonic kidney cells HEK293 or in human neuroblastoma cells SH-5YSY. In addition, rate-limited DA synthesis enzyme tyrosine hydroxylase mRNA was significantly low in the SH-5YSY cells transfected with two variant genes. These data suggest that the variants in the NURR1 gene might be PD-related mutations. We,

Studies

41

therefore, hypothesize that diminished expression of the NURR1 gene (loss of function), induced by the mutations in the gene, predisposing to DAergic neuron dysfunction, may represents a potentially important risk factor for Parkinson's disease. To test this hypothesis, we propose to study the relationship between the genotype of the mutations and the phenotype of the disease, and to investigate the underlying mechanisms. First (Aim 1), we will assay for the mutations, genotypes, and phenotypes in the first-degree members of all 10 fPD patients with the identified NURR1 mutations to determine the haplotype linkage, relationship between genotype and phenotype. Second (Aim 2), we will investigate if the mutations in NURR1 gene are specific for Parkinson's disease by analyzing the gene mutations in a total of 400 NC, 300 sPD, and 120 non-PD neurological disorders. Finally (Aim 3), we will determine the mechanisms by which the mutant genes alter NURR1 expression and DAergic neuronal dysfunction. The proposed experiments, which will take approximately four years for completion, will be conducted in parallel with a pilot study to generate a mouse model carrying the NURR1 mutations. The outcomes of the proposed study will improve our understanding of the role of NURR1 gene in the pathogenesis of Parkinson's disease, and may lead to potential therapeutic interventions, as well as means for diagnosing individuals having an increased risk of developing the disease.

Project Title: ORGANOCHLORINE EXPOSURE, GENETIC POLYMORPHISM AND PARKINSON'S DISEASE Principal Investigator & Institution: Berkowitz, Gertrud S.; Professor; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2001; Project Start 01-MAY-1995; Project End 31-MAR-2006 Summary: (Taken from application) Parkinson?s disease (PD) is a progressive, disabling disorder of the central nervous system characterized by tremors at rest, muscle rigidity, slowness, imbalance and, in later stages, often dementia. It is caused by loss of neurons in the substantial nigra that produce dopamine. Approximately half a million Americans are estimated to be affected by PD. Recent data suggest that environmental exposure, possibly in concert with genetically determined vulnerabilities, contribute to causation of PD; particularly in patients with onset of disease above age 50. The study will examine 300 cases of PD whose diagnoses have been confirmed by strict, standardized criteria and 300 controls with "minor" neurologic disorders not involving the basal ganglia. A blood sample will be obtained and a detailed questionnaire will be administered to each case and control. The groups will be half male, half female. All eligible minority patients will be enrolled. Cases and controls will be matched on age, gender, and race. This proposal has two inter-related biomedically based, epidemiologic objectives. We propose to determine: 1) whether serum organochlorine levels and/or a past history of exposure to pesticides are elevated in patients with Parkinson s disease; 2) whether polymorphisms in specific enzymes related to pesticide metabolism are more common in patients with PD; and 3) whether there is evidence for a gene-environment interaction. A more exploratory objective is to evaluate whether diet, particularly intake of antioxidants, may protect against development of PD. To test the hypothesis that organochlorine levels, the most common type of chemical pesticide used between 1940 and 1970, are increased in PD patients, DDT, DDE, Dieldrin, and oxychlordane will be determined and compared between cases and controls.

Project Title: OXIDATIVE INJURY IN PARKINSONS DISEASE Principal Investigator & Institution: Ferrante, Robert J.; Professor; Neurology; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2001; Project Start 01-APR-1998; Project End 31-MAR-2003 Summary: Oxidative stress has been proposed as a critical mechanism underlying metabolic dysfunction in diseases and aging and has been implicated in both apoptotic and necrotic cell death. Oxygen-derived free radicals are a normal byproduct of respiration and oxidative metabolism. Normally cells have efficient protective mechanisms which can quench radicals. When there is a compromise in cellular antioxidants or an increase in production of free radical species, neuronal damage occurs. An increasing body of evidence has implicated oxidative damage in the pathogenesis of Parkinson's disease (PD), including evidence of increased lipid peroxidation, protein oxidation, and oxidative damage to both nuclear and mitochondrial DNA directly associated with the known topographic and neuronal distribution of pathology observed within PD. The investigators preliminary studies may provide the strongest evidence yet, and they hypothesize that a connection exists between the pathology observed in PD and oxidative damage leading to metabolic dysfunction in this disorder. Their first Specific Aim is to determine the topographic distribution of markers for oxidative damage to protein, lipid, and DNA fractions in postmortem PD brains, using antibodies to several epitopes associated with oxidative damage. They will provide a direct assessment of markers for oxidative damage to determine if they are altered and subsequently correlate them with the selective neuronal vulnerability and the neuro-pathologic hallmarks associated with PD. Their goal will be to develop biochemical markers which may be useful for diagnostic purposes, monitoring disease progression, and the effectiveness of therapeutic interventions. The second Specific Aim will utilize transgenic animal models and therapeutic interventions to assess the role of oxidative stress in MPTP neurotoxicity. The systemic administration of the toxin MPTP in experimental animals replicates the neuropathological, neurochemical, and clinical features in PD, causing cell death by inducing oxidative stress. They will examine whether transgenic mice with a knockout of the manganese superoxide dismutase gene and neuronal nitric oxide synthase gene, as well as those overexpressing bcl-2 show increased vulnerability or resistance, respectively, to MPTP neurotoxicity. They will investigate the use of novel therapeutic strategies, using free radical spin traps, neuronal nitric oxide synthase inhibitors, and dietary creatine supplementation to block MPTP neurotoxicity. These studies will have direct relevance to understanding the pathogenesis of PD and to developing new therapies. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Summary: Parkinson's Disease (PD) is one of the most frequent neurodegenerative disorders. It is an extrapyramidal movement disorder characterized by the progressive loss of dopamine (DA) neurons in substantia nigra (SN). Recent progress in linkage studies on patients with familial PD has led to the identification of several genes implicated in this disease. One of these genes, parkin, is linked to Autosomal RecessiveJuvenile Parkinson's Disease (AR-JP). Deletions, truncations, and point mutations of parkin in AR-JP patients are correlated with their PD symptoms. However, it is not clear whether the loss of function for this gene directly causes PD, and if so, how does it occur? We propose to answer these questions by generating the parkin knockout mice. They will be used to study whether the deletion of parkin directly leads to selective loss of nigral DA neurons, and PD-like symptoms in mice. Since parkin is widely expressed in many tissues, and yet the progressive cell death is restricted to DA neurons in SN, we hypothesize that parkin may interact with specific proteins in these neurons to sustain their survival. To test this hypothesis, we propose to identify proteins that interact with parkin by using the yeast two-hybrid system. Once these proteins are identified, we will investigate their roles, in association with parkin, in the survival of nigral DA neurons. The specific goal of this project is to understand the in vivo function of parkin and its role in the etiology of AR-JP. As AR-JP and the sporadic form of PD share many similar clinical symptoms and pathological hallmarks (e.g. death of nigral DA neurons), knowledge gained from the study of parkin may shed some light on the potentially common mechanism for PD. It is our long-term objective to use this mouse genetic model to elucidate the molecular and cellular processes that lead to the progressive and selective death of nigral dopaminergic neurons and locomotor dysfunction in PD. This animal model would also be a valuable tool for the development of more effective therapeutic strategies for PD patients. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: PARKINSON DISEASE NEUROPROTECTION CLINICAL TRIAL CENTER Principal Investigator & Institution: Manyam, Bala V.; Professor of Neurology; Scott and White Memorial Hospital 2401 S 31St St Temple, Tx 76508 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): This application is in response to the Parkinson agenda for the NIH for the initiation of a randomized controlled clinical trial to test potential neuroprotectants in patients with early Parkinson's disease. The neuroprotectants to be tested in the trial have not yet been chosen and will be selected by an NINDS-appointed oversight committee. It is expected that NIH will fund 42 Parkinson's Disease Neuroprotection Clinical Centers to the institutions who demonstrate the ability to recruit subjects and provide high quality data for the trial(s). This application describes the characteristics of the staff and Parkinson's disease clinical center at Scott & White Clinic/Texas A & M College of Medicine that will be able to fulfill these goals. The following specific aims will be met subject to final common protocol finalized by the NINDS-appointed oversight committee. 1). Recruit 12 or more patients in the early stages of Parkinson's disease for the pilot study. 2). Recruit 72 or more patients for the main study once the final neuroprotectant is chosen from the initial pilot studies. The above patients will be in the early, mild Parkinson's disease, not yet requiring symptomatic treatment and unexposed to prior treatment with levodopa/dopamine agonist/selegiline (within four months). 3). For primary outcome measure to assess the degree of Parkinson's disease, and its progression the Unified Parkinson's Disease Rating Scale (UPDRS) (or one selected by NINDS-appointed

44

Parkinson’s Disease

oversight committee) will be followed for a highly reliable functional outcome or disability scale that is multi-modal in each subject and other protocols that may be implemented with the subject and investigator remaining "blinded" as to treatment assignment through the duration of the study. 4). For secondary outcome measures, monitor any adverse events from medication(s), quality of life measurement, depression, dementia and others by use of appropriate scales included in the final common protocol (such as Adverse Reaction Form, Hamilton Depression Scale and Mini-Mental State Exam) over the duration of the study. The PI has a proven track record in having participated in a large number of clinical trials involving early Parkinson's disease patients, has been involved in drug development for Parkinson's disease and has a team of well qualified staff, with access to large number of early Parkinson's disease patients including women and minority patients, through a network of a large primary care physicians along with a long-term track record of involvement in both laboratory and clinical care in the treatment of Parkinson's disease. Thus, the investigators have adequate experience, resources, and proven ability to recruit suitable early Parkinson's disease subjects and carry out the clinical trial to meet the requirements of RFA-NS-02-010 in a timely manner.

In PD, there is a prolonged course of progressive neuronal loss which is not altered by existing treatments. The development of neuroprotective strategies is therefore important to lessen the medical, societal, and economic impact of PD-related disability Patients will be recruited with early Parkinson's disease who have been symptomatic for fewer than five years, and who have received levodopa or dopamine agonists for no more than six months. Patients will be followed clinically over a period of three years to assess the potential neuroprotective benefit associated with a drug or drugs chosen by the Steering Committee. Although the multi-center trial will be based on clinical rather than surrogate endpoints, at this site, magnetic resonance imaging will be used to obtain a quantitative index of regional brain iron concentration which we hypothesize to correlate with disease progression.

Parkinson’s Disease

Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: Parkinson's disease (PD) affects about 1 million people in North America. Medications, such as levodopa, and some surgical approaches are available for PD, but offer only symptomatic therapy. New information contribute to current optimism that gene therapy might correct the molecular disturbances of PD, alleviate the symptoms of the illness and/or in retarding disease progression. Setbacks in gene therapy for other diseases underscore the importance of a purposely deliberate and careful approach that demands substantial assurances of safety and potential efficacy in advance of human testing. It is this philosophy of conservatism that will characterize the activities of our group. A coordinated stepwise progression from basic research through exhaustive preclinical evaluation prior to clinical testing is required. A multicenter, multidisciplinary collaborative group (The PD Gene Therapy Study Group [PDGTSG]) has formed and seeks support for those activities that will lead to a large-scale clinical trial of gene therapy for patients with PD. The PDGTSG consists of three different components: Cores, Principal Projects, and Pipeline Projects. Core A. Administrative Core (PI: Dr. Federoff): Houses a Steering Committee, and Vector (Chair: Dr. Lowenstein), Human Subjects/Clinical Assessment (Chair: Dr. Kurlan), Bioethics (Chair: Ms. Greenlaw), Intellectual Property (Chair: Ms. Hunter) and Biostatistics Modules (Chair: Dr. Oakes).

Summary: (provided by applicant): Parkinson's disease (PD) is a neurodegenerative disorder affecting approximately one million Americans. All patients develop a gradually progressive combination of signs and symptoms, including tremor, rigidity, slowness of movement, drooling, low volume speech, micrographia, gait and balance difficulty, and difficulty with activities of daily living. It is known that patients with PD have a loss of dopamine containing neurons projecting from the substantia nigra to the striatum, and most clinical signs and symptoms respond to replacement therapy with doparminergic medications (ie. levodopa, dopamine agonists). However, the underlying mechanism of neurodegeneration is unknown and therefore, to date, there is no treatment to cure or slow the progression of the disease. Many treatments have been hypothesized to be neuroprotective based on in vitro studies and animal data, but clinical trials have not found these drugs to be neuroprotective in patients with PD. The lack of a neuroprotective treatment has been a serious problem for patients, caregivers, health professionals, and for the economy. As the disease progresses the cost of care increases, with estimates of annual cost for medical care going from $3,000/yr early in the disease course to $15,000/yr in later stage disease. Finding a medication(s) that will slow or halt the progression of PD is therefore a major goal of PD research. To this end creating a multi-center study group to run clinical trials of potential neuroprotective agents has been set as a goal of the NIH. This application has, as its specific aim, to be one of the NIH Clinical Centers for neuroprotection treatment trials. This application proposes to create a consortium of centers at the Mayo Clinic and Sun Health Research Institute in order to best be able to enroll patients with early PD for neuroprotection treatment trials. With the mandate to enroll two patients/month for 42 months, the proposed consortium expects to meet these recruitment goals. Mayo Clinic Scottsdale, Mayo Clinic Jacksonville, Mayo Clinic Rochester, and Sun Health Research Institute, all have clinical centers that specialize in the care and treatment of patients with PD, and all have well established clinical trials experience. The resources are available to run clinical trials with a dedicated physician staff of 10 neurologists specializing in treatment of Parkinson's Disease at these four sites, along with nursing staff and the physical plant required. The protocols will be developed by the PIs of the various clinical centers along with NIH staff. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

This site has three board-certified neurologists trained in movement disorders who will participate in this proposed project. Upon implementation of this project these neurologists will collaborate to conduct a pilot trial of an agent to prevent disease progression in PD. Subsequently, additional collaboration with the other clinical center sites will lead to at least one multicenter trial. This project will help to maintain a stable infrastructure for the administration of the clinical trial(s) in neuroprotection related to Parkinson's disease. In addition, the conduct of this type of clinical trial(s) will generate a sample of patients with early PD who may be willing to participate in genetic studies. Similarly, subjects may be willing to participate in studies to identify markers from blood or

Summary:The Medical College of Georgia (MCG) Movement Disorders Clinic (MDC) is uniquely qualified to be a clinical center for the proposed neuroprotective trial in Parkinson's Disease (PD) because of the varied patient population. The clinic has been operational since 1985 at the MCG and the Augusta Veterans Affairs Medical Center (VAMC). Over 700 patients with PD who are in both early and advanced stages of the disease are evaluated and treated each year at MCG and the VAMC. Kapil D. Sethi, MD, FRCP (UK) and the entire research team have extensive experience in caring for PD patients and conducting clinical drug and research trials. The existing referral base is strong, consisting of general neurologists in the local area and surrounding Primary Care Providers. The local PD support group was started ten years ago under the guidance of the Dr. Sethi. The support group is actively involved with the MDC and is helpful in the education of newly diagnosed PD patients and their families. Long-Term Objectives:1. To delay the progression of PD through the use of medications while maintaining quality of life.2. Discover indicators of those susceptible to PD and prevent or delay onset of the disease.3. Ultimately, find a cure for PD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

While a number symptomatic therapies have been developed, no treatment has been identified that halts or slows this progressive disorder. For a number of reasons, we believe that it is appropriate to begin a prospective clinical trial of one or more of the more promising agents to determine whether they offer benefit. The aim of this application is to participate as a clinical center in a collaborative study of neuroprotective agents. The agents and protocol will be specified by NINDS. UCSF has a long history in providing subspecialty care for subjects with PD. The UCSF Parkinson's Disease Clinic & Research Center (PDCRQ has been involved in a number of clinical trials to elucidate the neurologic dysfunction underlying PD as well as testing a variety of novel treatments for PD. This research has included a number of industry sponsored treatment trials for subjects with early to advanced PD. A large diverse, local population provides a reliable source of motivated subjects for clinical research. The experience of the UCSF PDCRC in evaluating, selecting and following subjects with PD make it an ideal candidate for a multicenter, prospective trial of a potential neuroprotectant therapy. The ideal neuroprotective treatment should be effective, inexpensive, well tolerated, safe, easy to administer, and have few interactions with common medications. A number of studies over the last decade 'in humans and experimental animals have demonstrated a local immunologic response mediated by microglia and a number of inflammatory cytokines. Moreover, several animal models of PD have demonstrated that anti-inflammatory medications can interfere with the local immunologic response, and that they may preserve function of dopaminergic neurons. Although emerging understanding of the pathogenesis of PD may provide an alternative candidate for a neuroprotectant therapy, we propose that an

It is our understanding that the study design will include 42 clinical sites, the use of two or more neuroprotective agents, and an initial pilot study followed by a larger trial of approximately 3000 subjects with early Parkinson's Disease. It is also our understanding that the protocol for this study is currently under development by representatives from the coordinating center, statistical center, the NINDS Oversight Committee and others. As a clinical site for the study, Dr. Mark Stacy and the research staff at the Muhammad Ali Parkinson Research Center (MAPRC) at Barrow Neurological Institute agree to recruit and follow the required number of participants for the duration of the study, collect accurate and timely data and strictly adhere to the protocol.As a major referral center for Parkinson's Disease patients in the southwestern United States, approximately 4800 PD patients are examined and treated annually at our site. The MAPRC has extensive experience in the execution of clinical trials in the Parkinson's population, averaging approximately 15 to 20 clinical research studies annually. If given the opportunity to act as a clinical center for the Parkinson Disease Neuroprotection trial we will recruit the appropriate number of eligible subjects, taking special effort to ensure adequate representation of females and minorities.

Prevalence estimates range from 0.7% to 3% among individuals aged 65 or older. The cause of Parkinson's disease is unknown although there is evidence for a combination of genetic and environmental factors. There is currently no medication proven to delay or arrest the progression of disease. As the world population shifts towards a higher proportion of elderly people in coming years and the number at risk for developing Parkinson's disease increases, the economic and social impact of the disease will grow significantly. The search for neuroprotective agents is vitally important. Our purpose is to develop a clinical center for The Parkinson's Disease Neuroprotection Trial in Honolulu. The study will be a multicenter, randomized, double blind, placebo controlled, clinical trial to determine whether two or more specific agents (still to be chosen) can provide neuroprotection in early Parkinson's disease (PD).

Project Title: PARKINSON'S DISEASE RESEARCH TRIAL: CLINICAL CENTER Principal Investigator & Institution: Shannon, Kathleen M.; Rush-Presbyterian-St Lukes Medical Ctr Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Idiopathic Parkinson's Disease (IPD) is the second most common neurodegenerative disease, affecting an estimated 500,000 Americans; there are 35,000 new cases of IPD annually in the United States. The disease follows a progressive course, culminating in death or severe disability after about 20 years. Although there are medications that help to alleviate the symptoms of IPD by increasing central levels of the neurotransmitter dopamine, there remains no treatment to slow the relentless progression of the underlying degenerative process. A number of potential mechanisms of cell death have been illuminated by studies of pathology, epidemiology and experimental toxin-induced parkinsonism in animals. These include oxidative stress, protein aggregation, mitochondrial dysfunction, indirect excitotoxicity and apoptosis. A number of putative neuroprotective agents including propargylamines, complex I cofactors, substances affecting the mitochondrial energy potential, amantadine and others are emerging from the laboratory or early clinical trials. The Movement Disorders Group, of the Department of Neurological Sciences, Rush Medical College proposes to serve as one of 42 clinical centers for the Parkinson's Disease Neuroprotection Clinical Trial.

Project Title: PHF-TAU IN NEURODEGENERATIVE DIESEASES OF GUAM Principal Investigator & Institution: Lee, Virginia M.; Professor; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-MAR-1997; Project End 31-MAR-2007 Summary: (provided by applicant): Neurodegenerative diseases that affect Chamorros in the Mariana Islands of the Western Pacific resemble Alzheimer's disease (AD), Parkinson's disease (PD) and Amyotrophic Lateral Sclerosis (ALS) elsewhere, but ALS, PD and dementia frequently co-occur in Chamorros, and this syndrome is known as Guam ALS/Parkinson dementia complex (ALS/PDC). However, unlike AD, PD and ALS in other populations, Guam ALS/PDC is characterized predominantly by abundant neurofibrillary tangles (NFTs) in central nervous system (CNS) neurons that progressively degenerate. ALS/PDC NFTs are indistinguishable from those in classic AD, but about 25% of ALS/PDC brains contain AD-like senile plaque (SP) deposits of Ab, and PD-like Lewy bodies (LBs) were detected recently with antibodies to asynuclein (a-syn) in more ALS/PDC brains than previously recognized indicating that ALS/PDC is not a "pure" tauopathy. However, the NFTs in both ALS/PDC and classic AD are intraneuronal aggregates of paired helical filaments (PHFs) formed by hyperphosphorylated tau (PHF-tau) composed of all 6 brain tau isoforms, while tau isoforms containing 3 or 4 microtubule binding repeats predominate in the tangles found in other tauopathies. Recently, we generated transgenic mice overexpressing 3R tau and surprisingly they developed an ALS/PDC-Iike phenotype to provide the first experimental evidence that NFT-like tau inclusions play a mechanistic role in ALS/PDC. Nonetheless, we also hypothesize that SPs and LBs contribute to the progression of ALS/PDC, and that oxidative/nitrative damage plays a role in the development of NFT which in turn contributes to mechanisms of SP and LB formation in this disorder. Thus, the Specific Aims of this project will test the hypothesis that brain degeneration in ALS/PDC results from accumulations of NFTs, SPs and LBs formed by tau, Ab and a-syn, respectively, that are induced to fibrillize and/or aggregate and oxidative/nitrative stress plays an important role in this process in ALS/PDC.

Summary: (from applicant's Abstract)The purpose of this exploratory ethnomedical study is to describe the gender specific health beliefs and self care practices of immigrant Latino adults receiving treatment for Parkinson's Disease (PD) and to contrast these beliefs with the medical/disease model of PD. Parkinson's Disease, a chronic progressive neurological condition, is the third most common neurologic disorder of the elderly. The prevalence and incidence of PD increases dramatically with age. PD is found in elderly Latinos, one of the fastest growing segments of the United States Latino population. Research has demonstrated that patients and health care practitioners frequently do not share the same beliefs about disease causation and treatment. This can cause faulty communication between patient and provider leading to decreased patient adherence with the prescribed treatment regimen. At present, there is no research describing Latino adults' understanding of their disease. Clinicians who provide care for Latino adults with PD require information to better understand their patients' health care needs to improve communication and to design meaningful health care interventions. The specific aims of this study are to a) describe the health beliefs and self care practices of immigrant Latino adults receiving treatment for PD, b) compare participants' health beliefs and self care practices with the medical model of PD diagnosis and treatment, c) compare men's and women's perceptions of the impact of PD on their lives, and d) develop and prioritize a list of gender-specific health care needs as perceived by participants. Study findings will be used to develop clinical interventions. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: PRENATAL ENDOTOXIN AS A MODEL OF PARKINSON'S DISEASE Principal Investigator & Institution: Ling, Zaodung; Assistant Professor; RushPresbyterian-St Lukes Medical Ctr Chicago, Il 60612 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2006 Summary: (provided by applicant): Current animal models of Parkinson's disease (PD) use high-dosages of dopamine (DA) neurotoxins to produce rapidly evolving lesions. We have recently shown that injection of the Gram (-) bacteriotoxin, lipopolysaccharide (LPS), into gravid female rats at embryonic (E) day 10.5 produces offspring born with fewer dopamine (DA) neurons. The 30-40% DA neuron loss routinely seen is still present after 4 months and presumed permanent. This DA neuron loss is similar to that seen in the PD patient since it is more pronounced in the lateral nigra and its ventral tier, spares the ventral tegmental area and calbindin immunoreactive DA neurons in the nigra, and is associated with reduced striatal DA and increased DA activity as well as tumor necrosis factor (TNFalpha). Exposure of these animals to the DA neurotoxin 6hydroxydopamine (6OHDA) after 4 months, produces a greater inflammatory response and further DA cell loss. We hypothesize that the elevated DA activity and TNF seen in adult animals as a result of prenatal LPS treatment will lead to increased production of reactive oxygen species (ROS) that will eventually overwhelm ROS detoxification systems leading to further, progressive DA neuron loss as a result of aging or low dose exposure to 6OHDA. Based on this hypothesis we will study rats exposed to prenatal LPS and determine if further DA cell loss occurs with aging (through 21 months; Aim 1). Aim 2 will examine the combined effects of prenatal LPS and postnatal 6OHDA at various ages and determine if the combined effects of these two treatments is additive or synergistic and if the magnitude of the DA neuron loss as a result of these two neurotoxins increases with age. Whether or not animals exposed to prenatal LPS and 6OHDA at a young age exhibit a greater rate of DA neuron loss as they age compared with animals treated later in life, will be evaluated in Specific Aim 3. The successful

54

Parkinson’s Disease

implementation of these Specific Aims will address the notion that prenatal exposure to bacterial endotoxin is a risk factor for PD. Moreover, they would further demonstrate that prenatal infections such as bacterial vaginosis can interact with postnatal neurotoxin exposure to produce a gradual, protracted DA neuron loss that could be useful as a new animal model of PD.

Project Title: PROTEOMICS OF COMPLEX 1 INHIBITION IN GSH-DEPLETED CELLS Principal Investigator & Institution: Gibson, Bradford; Professor; Buck Institute for Age Research Novato, Ca 94945 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): Oxidative stress appears to play an important role in degeneration of dopaminergic neurons of the substantia nigra (SN) associated with Parkinson's disease (PD). The SN of early PD patients have dramatically decreased levels of the thiol tripeptide glutathione (GSH). GSH plays multiple roles in the nervous system both as an antioxidant and a redox modulator. Recently, we generated dopaminergic cell lines in which levels of GSH can be inducibly down-regulated via doxycycline (dox) induction of antisense messages against both the heavy and light subunits of gamma glutamyl cysteine synthetase (gamma-GCS), the rate-limiting enzyme in glutathione synthesis. Down-regulation of GCS results in reduction in mitochondrial GSH levels, increased oxidative stress, and decreased mitochondrial function. Interestingly, decreases in mitochondrial activities in GSH-depleted PC12 cells appears to be due to a selective inhibition of complex I activity similar to that observed in PD. This loss in enzymatic activity appears to be a result of cysteine oxidation which is reversible by the thiol-reducing agent dithiothreitol. These results suggest that early observed GSH losses in PD may be directly responsible for the noted decreases in complex I activity and the subsequent mitochondrial dysfunction which ultimately leads to dopaminergic cell death associated with the disease. The hypothesis we will examine in this proposal is that oxidation of specific cysteines within the protein subunits of mitochondrial complex I are responsible for the selective inhibition of its activity following GSH depletion. To accomplish this goal, we will employ a series of sulfhydryl-specific probes to assess the redox states of cysteine thiol groups in complex I proteins. We will use highly sensitive mass spectrometry-based proteomics methods to identify the cysteine residue(s) that are responsible for this reversible loss of mitochondrial complex I activity. We will also examine complex I proteins for other types of oxidative damage (both reversible and irreversible) that may contribute to this loss of activity. These data should provide valuable insight into the effect of oxidative stress on mitochondrial physiology as it relates to PD, particularly the structural basis for alterations in mitochondrial function. Knowledge of the molecular details of complex I dysfunction and the identification specific subunit(s) that are involved may point us towards novel therapeutic targets for the disease and provide key data on whether thiol replacement therapy is a viable option for treatment of the disease. Once identified, presence of these alterations will be assessed in future years in both an antiGSH transgenic mouse model of Parkinson disease as well as in Parkinsonian brains.

Project Title: RESTORATION OF DOPAMINE FUNCTION IN PARKINSON'S DISEASE Principal Investigator & Institution: Gerhardt, Greg A.; Director, Morris K. Udall Parkinson's Ce; Anatomy and Neurobiology; University of Kentucky 109 Kinkead Hall Lexington, Ky 40506 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-JUL-2004 Summary: The neuroestorative and neuroprotective tropic actions of GDNF on midbrain dopamine (DA) neurons provide a promising therapeutic approach for the treatment of Parkinson's disease. As with many tropic factors, optimum success of this tropic factor depends on focal and controlled delivery of the protein to affect the function of DA neurons, without producing unwanted side effects. It is our central hypothesis that chronic intracerebroventricular or intraputamenal GDNF willproduce effects on damaged DA neurons with greater efficacy, potency and reduced side effects as compared to other methods of delivery. 1. We propose to use a novel indwelling pump that can deliver GDNF chronically in the freely-moving MPTP-lesioned monkey to evaluate two sites of delivery: the lateral ventricle and the putamen. 2. We will also investigate washout of GDNF and re-instatement of the trophic factor in both infusion paradigms. The different highly integrated Projects and Cores will provide key data regarding the functional effects of chronic GDNF treatments to DA neurons, and form the foundation for a Parkinson's Disease Center of Excellence. Project 1 will use microdialysis, in vivo electrochemistry and postmortem HPLC-EC methods to study the nigrostriatal pathway of unilateral MPTP-lesioned monkeys that have received chronic infusions of GDNF. Project 2 will investigate the behavioral consequences of the GDNF infusions and study potential functional changes to DA neurons using fMRI methods. Project 3 will carryout tract tracing and immunohistochemical measures of DA neurons in the same groups of chronically treated monkeys. The Cores A-D will all provide needed support for the experiments outline in Projects 1-3. These studies will answer key questions regarding the chronic delivery of a trophic factor in freely-moving and behaving rhesus monkeys. Such data could lay the foundation for the use of trophic molecules for the treatment of Parkinson's disease in humans. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

MTDNA

MUTATIONS

IN

Principal Investigator & Institution: Khrapko, Konstantin; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 31-MAY-2006 Summary: (Adapted from the abstract provided by the applicant): The long-term goal of the proposed research is to study the mechanisms responsible for the slow progression of late-onset neurodegenerative diseases. The understanding of these mechanisms may help to find ways to make these processes even slower, thus moving the onset of these debilitating diseases outside the normal human lifespan. Specifically, we propose to test the hypothesis that accumulation of somatic mutations in mtDNA of critical cell types in the brain is one of the conditions necessary for the progression of at least some neurodegenerative processes. One of the possibilities is that once the fraction of mutated mtDNA in specific cells exceeds a certain threshold, these cells become sensitive to biochemical insults associated with some diseases. This hypothesis has arisen from the preliminary finding that individual pigmented neurons in substantia nigra accumulate very high levels of mtDNA deletions, which are highly likely to compromise cell's

56

Parkinson’s Disease

resistance to various stresses. Moreover, there are indications that cells with a heavy mutational load are the first to die in Parkinson's brain. It is also possible that progression of the disease accelerates accumulation of mutations thus creating a positive feedback. The efforts will be focused first on Parkinson's Disease (PD) patients and pigmented neurons of substantia nigra. Then research will be extended to Alzheimer's Disease (AD), Huntington's Disease (HD) and the various corresponding brain areas and critical cell types. The Specific Aims of the proposal are: 1) To develop and optimize the arsenal of methods necessary for the precise quantification and characterization of mtDNA mutations in single cells of the brain. These methods will include laser capture micro-dissection for single cell isolation, amplification of full-length mitochondrial genomes from single cells, single cell competitive PCR, and single cell limiting dilution PCR. 2) To identify brain areas and cell types in which mtDNA mutations are most likely to contribute to neurodegeneration. This will be done by measuring mutation load in individual cells of substantia nigra, cortex and putamen that are known to be rich in mtDNA deletions and are critical for PD, AD, and HD, respectively. 3) To test the hypothesis that clonal expansions of mtDNA mutations in individual cells contribute to mitochondrial defects and to neurodegeneration and death of neurons. This will be done by comparing the mutational load of cells that stained positive for various markers of mitochondrial dysfunction, cell degeneration and death to non-staining control cells. We will also study the distribution the mutations as a function of age and the presence and severity of the disease. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: SAM-E TREATMENT OF DEPRESSION IN PARKINSON'S DISEASE Principal Investigator & Institution: Dirocco, Alessandro; Beth Israel Medical Ctr (New York) 1St Ave at 16Th St New York, Ny 10003 Timing: Fiscal Year 2002; Project Start 20-SEP-2002; Project End 31-MAY-2005 Summary: (provided by applicant): S-Adenosyl-methionme (SAM-e) is a molecule present in all eukaryotic cells, where it serves as the methyl-group donor for a number of metabolic functions. In the nervous system, SAM-E is essential in the metabolism of cathecholamines and may play an essential role in receptor stabilization and myelin formation and repair. SAM-a is available in the USA as a food supplement and is promoted as a mood enhancer. Parkinson's disease (PD) is commonly associated with depression, but conventional antidepressants have limited efficacy in parkinsonian patients and may exacerbate motor symptoms. SAM-a improves dopamine transmission, may have a beneficial effect on dopamine receptors and may be a good alternative to the currently used antidepressants. We have conducted a ten-week pilot study of SAM-e in thirteen depressed patients with PD. All patients had been previously treated with other anti-depressant agents and had no significant benefit or had intolerable side effects. Eleven patients completed the study, and ten had at least a 50% improvement of the 17point Hamilton Depression Scale (HAMD), while one patient did not improve. The mean HAMD score before SAM-e treatment was 27.09 greater than or equal to 6.04 SD), and was 9.55 +/-7.29 SD) after treatment (p Thr mutant alpha -synuclein protects neuronal cells from apoptotic stimuli.

Donepezil to Treat Dementia in Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: This study will evaluate the safety and effectiveness of donepezil (Aricept) for treating mild dementia in patients with Parkinson's disease. Donepezil is approved for treating patients with Alzheimer's disease, whose memory and cognition problems are similar to those of patients with Parkinson's disease who are affected by dementia. Donepezil prevents the breakdown of a chemical messenger called acetylcholine, which is involved in memory and other cognitive functions, and may improve cognition in patients. Patients 40 years of age and older with Parkinson's disease who have mild to moderate dementia may be eligible for this 6-month study. It involves 6 clinic visits of approximately 2 hours each, described below. Candidates will be screened for participation during Visit 1. - Visit 1 (screening visit): Study candidates will have a medical history, physical and neurological examinations, electrocardiogram (EKG), and possibly blood tests. They will also undergo neuropsychological testing (tests of memory, language, mood and, other brain functions) and fill out a quality of life questionnaire. Those enrolled will be randomly assigned to receive either donepezil (5 mg per day) or placebo-a look-alike pill with no active ingredients. After 4 weeks, the dose of donepezil will be increased to 10 mg per day. Patients who do not tolerate the higher dose will have it reduced to 5 mg. Those who do not tolerate the 5-mg dose will be taken off medication but will continue to be followed and tested. - Visit 2 (week 7): Patients will have a neurological examination and neuropsychological testing and will fill out a quality of life questionnaire. - Visit 3 (week 10): Patients will repeat the evaluations done during visit 2 and will stop taking the study medication. - Visit 4 (week 16): Patients will repeat the evaluations done during visit 2 and will have their study medication switched. That is, patients previously on placebo will be switched to donepezil, and patients who were taking donepezil will be switched to placebo. After 4 weeks, the dose of donepezil will be increased to 10 mg per day. Patients who do not tolerate the higher dose will have it reduced to 5 mg. Those who do not tolerate the 5mg dose will be taken off medication but will continue to be followed and tested. - Visits 5 and 6 (weeks 23 and 26): Patients will repeat the evaluations done during visit 2. This study is being conducted at the National Institutes of Health, the University of Pennsylvania, and Northwestern University Phase(s): Phase IV Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00030979



Farming and Movement Evaluation Study (FAME) Condition(s): Parkinson's Disease; Movement Disorders Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Environmental Health Sciences (NIEHS) Purpose - Excerpt: The long term goal of this research is to elucidate the cause(s) of Parkinson's disease, with a focus on environmental determinants. We propose to investigate the relationship between Parkinson's disease and exposure to pesticides and

176 Parkinson’s Disease

other factors by conducting a nested case-control study in the Agricultural Health Study. Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00042120 •

Genetic Analysis of Parkinson's Disease Condition(s): Parkinson's Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Human Genome Research Institute (NHGRI) Purpose - Excerpt: The purposes of this study are to identify the gene or genes responsible for an inherited form of Parkinson's disease and learn more about how the disease develops. In Parkinson's disease, a deficiency of a brain chemical called dopamine impairs the function of the part of the brain that controls movement. As a result, patients may have difficulty moving or they may have uncontrolled movements of their hands and fingers. Parkinson's disease usually occurs sporadically, with no known cause. In a few families, however, the disease seems to be inherited through a gene mutation (change). There is a 50-50 chance that a parent with the mutated gene will pass it on to a child. Children who do inherit the abnormal gene may or may not go on to actually develop Parkinson's disease-the relative chance of this happening is not known. Individuals 18 years of age and older from families in which Parkinson's disease appears to be inherited may be eligible for this study. Participants will have a brief medical examination, provide a personal and family medical history, and have a small blood sample (2 tablespoons) taken for genetic studies. The total time required for the study is about 1 to 2 hours. Participants are encouraged to meet with a NIH investigator or with a genetics specialist in their local area before testing to talk about the possible implications for themselves and their families of the test results.

Clinical Trials 177



Investigating the Safety of srTMS in the Treatment of Parkinson's Disease Condition(s): Parkinson Disese Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: Super rapid transcranial magnetic stimulation (srTMS) is a method of brain stimulation that may be able to change the electrical activity of the nerve cells of the brain. It has been proposed and tested as a treatment for brain disorders, including Parkinson's disease. The purpose of this study is to use a device called the magnetic stimulator to investigate the safe limit of srTMS, such as intensity of stimulation and the number of magnetic pulses that may lead to excessive brain stimulation. Ten patients with Parkinson's disease-whose main problems are slowness of movement and difficulty walking-will participate in this study. They will be asked to come to the laboratory for one experiment. Before and after srTMS treatment, investigators will test participants' brain function with a series of psychological tests and an EEG (electroencephalogram). The srTMS treatment is performed by placing an insulated coil of wire on the scalp and passing a very brief electrical current through the wire coil. The experiment will last 2 to 4 hours.

JP-1730 to Treat Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: This study will evaluate the effects of an experimental drug called JP1730 on Parkinson's disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. JP-1730 affects chemical messengers believed to affect Parkinson's disease symptoms. Patients between 30 and 80 years of age with relatively advanced Parkinson's disease may be eligible for this 3phase study. - Phase 1 - Baseline evaluation Participants will be evaluated with a medical history, physical examination, detailed neurologic evaluation, routine blood tests, urinalysis and an electrocardiogram. They will also have a 24-hour holter monitor (heart monitoring) and cardiology consultation. A chest X-ray and MRI or CT scan of the brain will be done if needed. Patients will, if possible, stop taking all antiparkinsonian medications except levodopa (Sinemet) for one month before the study begins and throughout its duration. (If necessary, patients may use short-acting dopamine agonists, such as Mirapex and Requip.) - Phase 2 - Dose Finding Phase For 2 to 3 days, patients will be admitted to the NIH Clinical Center for a levodopa (a dopamine agonist) dosefinding procedure. For this procedure, patients stop taking Sinemet and instead have levodopa, and subsequently apomorphine, infused through a vein. During the infusions, the drug dose is increased slowly until either 1) parkinsonian symptoms improve, 2) unacceptable side effects occur, or 3) the maximum study dose is reached. Symptoms are monitored frequently to find the optimal dose. (Patients who have had dosing infusions in the last 3 months will not have to undergo this phase of the study.) Phase 3 - Active Study Phase Within 3 months of the dose-finding phase, treatment will

178 Parkinson’s Disease

begin. Patients will receive seven doses of JD-1730 or placebo (an inactive substance) via puffs from an oral spray together with levodopa infusions over a 3-week period. The doses are given on days 1, 2, and 3 of the first week and then approximately twice a week for the next 2 weeks. For these doses, patients are hospitalized 4 days the first week and 2 days each for the next 2 weeks. All participants will receive placebo at some time during the study, and a few patients, selected at random, will receive only placebo the entire 3 weeks. The procedure for the infusions is the same as that for the dosefinding phase, with frequent evaluation of symptoms. Also, small blood samples are drawn up to three times each study day. At the end of the third week, patients will be discharged from the hospital. Their anti-parkinsonian medications may be readjusted, as needed. Patients will be contacted 2 weeks after the end of the study for a check on side effects and, if necessary, will be scheduled for a follow-up evaluation at the clinic. In addition to the above procedures, patients will be asked to have an optional lumbar a puncture (spinal tap) on the first and last days of the study to measure various brain chemicals and drug levels that cannot be measured in blood and urine. For this procedure, a local anesthetic is given and a needle is inserted in the space between the bones (vertebrae) in the lower back. About 2 tablespoons of fluid is collected through the needle.

Parkinson's Diseases Susceptibility Genes and Pesticides Condition(s): Parkinson's Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Environmental Health Sciences (NIEHS) Purpose - Excerpt: Parkinson's disease (PD) occurrence is higher in rural than in urban populations of industrialized countries. Epidemiologic and human tissue studies suggest that pesticides may be responsible for causing dopaminergic cell death at increased rates. While many pathophysiologic pathways may be involved in the neurodegeneration responsible for PD, genetic factors are likely to determine a general susceptibility to neurodegeneration.

PET Scanning in Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Human Genome Research Institute (NHGRI) Purpose - Excerpt: This study will compare brain blood flow and the brain's use of dopamine in patients with Parkinson's disease, their family members and normal volunteers. Dopamine is a chemical normally found in the part of the brain involved in controlling movement. This chemical is lacking in people with Parkinson's disease, and patients have difficulty initiating or controlling some body movements. Usually, Parkinson's disease develops in people without any known cause. In a few families, however, three or more people are affected, suggesting these families may have a genetic alteration that makes them more prone to develop the disease. Normal healthy volunteers and members of families in which three or more people have Parkinson's disease may be eligible for this study. Candidates will have a physical examination and provide a personal and family medical history. Volunteers will also have a neurological examination. Participants will undergo PET scanning. One hour before the scan, subjects are given a medication called Carbidopa, which maximizes the usefulness of the scans. For the procedure, the subject lies on a table in the scanner, a catheter (thin plastic tube) is inserted into an arm vein, and a baseline scan is done. Radioactive water is then injected through the catheter and another scan is done. During this scan, the subject is asked questions to stimulate blood flow in certain areas of the brain. Up to 10 injections are given, with different questions asked each time. The total time for the scans is not more than 1 hour. A final scan, which may last up to 2 hours, is then done. Dopamine is injected into the catheter before the scan begins. When it is completed, subjects are instructed to empty their bladder immediately and then every 2 hours for the rest of the day to reduce the exposure to radioactive material. Shortly afterwards, the subject has a magnetic resonance imaging (MRI) scan. This scan is used to help interpret the information obtained from the PET scans. MRI uses radio waves and a magnetic field to image structural and chemical changes in tissues. For this procedure, the subject lies still on a table that is moved into the middle of a narrow circular scanner. An intercom system permits communication with the staff member performing the study at all times during the procedure.

Single Photon Emission Computed Tomography to Study Receptors in Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: This study will use single photon emission computed tomography, or SPECT (see below), to examine brain nicotine receptors in evaluating the role of a chemical called acetylcholine in memory and other problems in Parkinson's disease (PD). Acetylcholine acts by binding to these nicotine receptors. Healthy normal volunteers and patients with Parkinson's disease 40 years of age and older, with or without dementia, may be eligible for this study. Candidates will be screened with physical and neurological examinations, a pen and paper test of memory and other mental functions, blood tests, and, for women of childbearing potential, a pregnancy test. Patients with cognition problems will have more intensive mental function tests. All participants will undergo the following procedures: - Magnetic resonance imaging (MRI): This test uses a strong magnetic field and radio waves to show structural and chemical changes in the brain. During the scan, the subject lies on a table in a narrow cylinder (the scanner). The time required in the scanner is about 1 hour, during which the subject is asked to lie very still for 10 to 15 minutes at a time. He or she can speak with a staff member via an intercom system at all times during the procedure. - SPECT: This nuclear medicine test produces a picture of the receptors in the brain. On the night

182 Parkinson’s Disease

before the scan, the day of the scan, and for 4 days after the scan, subjects take an oral dose of potassium iodide to protect the thyroid gland from the radioactive tracer used in the SPECT procedure. (People allergic to potassium iodide will take potassium perchlorate instead.) Before the scan, small radioactive markers containing 99Tc are glued to the subject's head. Two catheters (thin, flexible tubes) are placed in veins in the arms to inject the radioactive tracer [123I]5-I-A-85380 and to draw blood samples. Another catheter is placed in an artery in the wrist to draw arterial blood samples. During the scan, the subject lies on a bed with his or her head held still with a head holder. The scans are taken over a 6-hour period after injection of [123I]5-I-A-85380. An electrocardiogram, respiration, and blood pressure measures are taken before the tracer is injected, then 5 minutes after the injection, and again 30 to 60 minutes after the injection. Blood and urine samples are collected 5 to 6 hours after starting the scan. Participants are asked to urinate at least every 2 hours for 12 hours after injection of [123I]5-I-A-85380 to decrease radiation exposure.

Spheramine(r) in advanced Parkinson's disease (The STEPS Trial) Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): Titan Pharmaceuticals; Schering-Plough Purpose - Excerpt: The purpose of the STEPS clinical research study is to evaluate the effect and safety of Spheramine implantation in patients with Parkinson's disease. Spheramine is a cell therapy that consists of human retinal pigment epithelial (RPE) cells attached to microscopic gelatin beads (microcarriers). The RPE cells produce L-DOPA and are believed to directly enhance brain levels of dopamine. This clinical study will enroll 68 participants with advanced Parkinson's disease. Half of the participants will be randomly (by chance) assigned to receive Spheramine, and half will receive placebo (sham or mock surgical treatment). If Spheramine is proven to be both beneficial and safe in this study, those participants who had the placebo treatment will be offered Spheramine at the end of the trial.

Study of Repetitive Transcranial Magnetic Stimulation in Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: This study will examine the effects of repetitive transcranial magnetic stimulation (rTMS) on Parkinson's disease symptoms. rTMS is a way of stimulating the brain that may be able to change the electrical activity of the nerve cells in the brain. It has been proposed as a treatment for brain disorders, including Parkinson's disease. In preliminary studies, some patients' symptoms improved; in some they worsened

Clinical Trials 183

temporarily, and some showed no change. Patients between 40 and 80 years of age with moderately severe Parkinson's disease, whose main problem is slowness of movement and stiffness, may be eligible for this study. Participants will be randomly assigned to one of two treatment groups: one will receive rTMS to parts of the brain involved in controlling movement; the other will receive sham, or placebo, stimulation. Nine treatments will be given over a 4-1/2 week period. Patients will take their Parkinson's disease medications during the study, but will stop taking the medicines for 4 to 5 hours before one of the sessions. For rTMS, an insulated wire coil is placed on the scalp. A brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the brain. The pulses are delivered in trains, or short bursts, lasting 1 second each. There will be 48 trains for a total of 1200 pulses per 24-minute session. The stimulation may cause muscle twitching in the scalp or face and may also cause small movements of the limbs. Just before and after each rTMS session, patients will have a neurologic examination, including an evaluation of walking. Their motor function tests will be recorded on videotape to document possible improvement and to allow physicians to rate the improvement. The physicians will not know which patients are receiving actual rTMS and which are receiving sham treatment. Ratings before the first and after the last rTMS sessions will be more detailed.

Studying Automatic Movements in Patients with Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: Parkinson's disease patients usually have difficulty making automatic movements. Automatic movements are movements people often make without conscious thought. The purpose of this study is to investigate regions of the brain that affect automatic movements and to understand the movements of Parkinson's patients. Investigators hope this knowledge will lead to better treatment for the disease. Thirty participants will be enrolled in this study. Each will give a medical history and undergo a brief physical exam. Participants will have two MRI scans, each lasting approximately 1.5 hours. During these scans, they may be asked to move their right or left hands or to remember some letters that they have been shown. Before undergoing the second scan, participants will be asked to practice the tasks until they can perform them correctly.

The Role of Dopamine in Motor Learning in Healthy Subjects and Patients with Parkinson's Disease Condition(s): Parkinson Disease; Healthy Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: This study will examine and compare what happens in the brains of patients with Parkinson's disease with that of healthy normal subjects while they train to react as fast as possible to the appearance of a visual signal. Particularly, we will measure the amount of the chemical dopamine released in the brain as well as the electrical activity during training. Indeed, patients with Parkinson's disease frequently complain of slowness and early fatigue during movements. These symptoms are believed to be related to a decrease of dopamine in the brain which may be associated with abnormalities in cerebral electrical activity. Adult patients with Parkinson's disease who are right-handed, do not have dementia, and are not depressed may be eligible for this study. Healthy volunteers who match patients in age, gender, handedness, and level of education will also be studied. Candidates will be screened with a medical history, physical and neurological examinations, memory test, mood evaluation, and urine toxicology. All participants will be required to stop taking any medications that can influence the central nervous system and to abstain from alcohol consumption for 1 week before the screening examination and during the study training period. Patients with Parkinson's disease will also be required to stop using antiparkinsonian medications for at least 12 hours before the first visit and each training session. Participants will have several 1-hour training sessions. During these sessions, they will sit facing a computer screen at a distance of about 32 inches (80 centimeters) from their eyes. Six permanent position markers will be displayed. A keyboard with six spatially compatible response keys will be within reach of their right hand. Participants will respond as quickly and as accurately as possible to the appearance of a stimulus (e.g., white circle) below one of the markers by pressing the spatially corresponding key. About a second later, the next stimulus will be displayed below one of the other markers, and so on. Reaction times and accuracy will be recorded. After 3 to 10 minutes of practice (one block), there will be a rest period during which the computer will display information about the subject's accuracy of movements and reaction time. Then, a new block will start. There will be about 6 to 20 practice blocks per training session. The number of training session will vary between 3 and 6 depending on accuracy and reaction time during the task. During each training session, subjects will have encephalographic (EEG) recordings to measure the electrical activity of the brain. In addition, they will have one or two positron emission tomography (PET) scans during the first training session, and some will also have one or two PET scans during the last session. For the PET scan, the subject will be injected with a substance called raclopride, which is taken up by the brain. The raclopride is tagged with a radioactive substance so that it can be detected by the PET camera. The amount of raclopride detected in the

Clinical Trials 185

brain will provide an indirect measure of the amount of dopamine released during training. Before or after one of the training sessions, participants will undergo magnetic resonance imaging (MRI) to study brain anatomy. MRI uses a strong magnetic field and radio waves to produce images of the brain. The subject lies on a table in a space enclosed by a metal cylinder (the scanner). The test takes about 45 to 60 minutes, during which the participant must lie very still for 10 to 15 minutes at a time.

Within-Subject, Dose-Escalation Trial of Continuously Infused Intracerebral (IC) Recombinant-Methionyl Human Glial Cell Line-Derived Neurotrophic Factor (rmetHuGDNF) for the Treatment of Subjects with Idiopathic Parkinson's Disease Condition(s): Parkinson Disease Study Status: This study is currently recruiting patients. Sponsor(s): National Center for Research Resources (NCRR) Purpose - Excerpt: Parkinson's disease is characterized by loss of neurons that produce dopamine in a region of the brain called the substantia nigra. In the early stages of the disease, the disease responds to agents that replace dopamine such as levodopa. Patients with more advanced disease have wide fluctuations in their response to levodopa, exhibiting on and off periods. This is due to continued degeneration of neurons. Recombinant-methionyl human glial cell line-derived neurotrophic factor (rmetHuGDNF or GDNF) is a neurotrophic factor that promotes survival of dopaminergic neurons. This is a protein produced by recombinant technology that is almost identical to the naturally produced factor. Results of animal studies indicate that GDNF has the potential to benefit patients with advanced Parkinson's disease. The purpose of this clinical trial is to determine whether GDNF works to relieve symptoms of advanced Parkinson's disease. The study will also test the delivery of GDNF using a catheter implanted into the putamen, the area of the brain associated with Parkinson's disease, and an infusion pump that is implanted under the skin in the abdomen or chest. GDNF will be placed into the pump and delivered through the catheter to the brain. The purposes of this study are to determine the potential benefits and side effects of GDNF. The performance and safety of the catheter/infusion pump system will also be assessed. The study will last for 6 months. Subjects will undergo neurological testing, computerized gait assessment and neurological imaging.

CHAPTER 6. PATENTS ON PARKINSON’S DISEASE Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “Parkinson’s disease” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on Parkinson’s disease, we have not necessarily excluded non-medical patents in this bibliography.

Patents on Parkinson’s Disease By performing a patent search focusing on Parkinson’s disease, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. 9Adapted from the United States Patent and Trademark Office: http://www.uspto.gov/web/offices/pac/doc/general/whatis.htm.

3-[4-(4-phenyl-1,2,3,6-tetrahydro-1-pyridyl)butyl]-5-hydroxy-indole methanesulfonate having sedating and anti-parkinsonism properties Inventor(s): Bergmann; Rolf (Reichelsheim, DE), Bottcher; Henning (Darmstadt, DE), Hausberg; Hans-Heinrich (Ober-Ramstadt, DE), Seyfried; Christoph (SeeheimJugenheim, DE) Assignee(s): Merck Patent Gesellschaft Mit Breschrankter Haftung (Darmstadt, DE) Patent Number: 4,914,114 Date filed: May 16, 1988 Abstract: 3-[4-(4-phenyl-1,2,3,6-tetrahydro-1-pyridyl)butyl]-5-hydroxy-indole methanesulfonate can be used in the therapy of Parkinsonism and is particularly readily soluble. Excerpt(s): The invention relates to the new compound 3-[4-(4-phenyl-1,2,3,6tetrahydro-1-pyridyl)-butyl]-5-hydroxyindole methanesulfonate (I). The underlying base (II) and the corresponding hydrochloride (III) are described in DE-OS 2,910,367. It has been found that I has considerably more favourable pharmacokinetic properties than III. Thus, for example, 100 mg/kg of I administered orally to Cynomolgus monkeys already lead to a sedating reaction, whilst this effect can be achieved with III only with doses above 500 mg/kg. I also has a considerably better solubility in water (0.921 g in 100 ml) than III (0.035 g in 100 ml). Web site: http://www.delphion.com/details?pn=US04914114__

Human SDR2 cDNA clone Inventor(s): Albone; Earl Francis (Conshohocken, PA), Kikly; Kristine Kay (Linfield, PA) Assignee(s): SmithKline Beecham Corporation (Philadelphia, PA) Patent Number: 6,090,579 Date filed: December 16, 1997 Abstract: SDR2 polypeptides and polynucleotides and methods for producing such polypeptides by recombinant techniques are disclosed. Also disclosed are methods for utilizing SDR2 polypeptides and polynucleotides in the design of protocols for the treatment of cancer, inflammation, autoimmunity, allergy, asthma, rheumatoid arthritis, CNS inflamation, cerebellar degeneration, Alzheimer's disease, Parkinsons disease, multiple sclerosis, amylotrophic lateral sclerosis, head injury damage, and other neurological abnormalities, septic shock, sepsis, stroke, osteoporosis, osteoarthritis, ischemia reperfusion injury, cardiovascular disease, kidney disease, liver disease, ischemic injury, myocardial infarction, hypotension, hypertension, AIDS, myelodysplastic syndromes and other hematologic abnormalities, aplastic anemia, male pattern baldness, and bacterial, fungal, protozoan and viral infections, among others, and diagnostic assays for such conditions. Excerpt(s): This invention relates to newly identified polynucleotides, polypeptides encoded by them and to the use of such polynucleotides and polypeptides, and to their production. More particularly, the polynucleotides and polypeptides of the present invention relate to 6-TM family, hereinafter referred to as SDR2 (stromal-cell derived receptor). The invention also relates to inhibiting or activating the action of such polynucleotides and polypeptides. Murine SDR2 was cloned from a bone marrow stromal cell line using a signal sequence trap method (Shirozu, M., et al., Genomics 37:273-280, 1996). Murine SDR2 contains a signal sequence and has six putative transmembrane spanning domains. Other six transmembrane spanning proteins function as ion transporters (Becker, D., et al., PNAS 93:8123-8128, 1996), water channel proteins (Misaka, T., et al., FEBS Lett. 381:208-212, 199; Jung, J. S., et al., PNAS 91:1305213056, 1994), iron transporters (Dix, D. R., et al., JBC 269:26092-26099, 1994) or have been linked to cellular activation and division (Gaugitsch, H. W., et al., JBC 267:11267-11273, 1992). This indicates that the 6-TM family has an established, proven history as therapeutic targets. Clearly there is a need for identification and characterization of further members of 6-TM family which can play a role in preventing, ameliorating or correcting dysfunctions or diseases, including, but not limited to, cancer, inflammation, autoimmunity, allergy, asthma, rheumatoid arthritis, CNS inflammation, cerebellar degeneration, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amylotrophic lateral sclerosis, head injury damage, and other neurological abnormalities, septic shock, sepsis, stroke, osteoporosis, osteoarthritis, ischemia reperfusion injury, cardiovascular disease, kidney disease, liver disease, ischemic injury, myocardial infarction, hypotension, hypertension, AIDS, myelodysplastic syndromes and other hematologic abnormalities, aplastic anemia, male pattern baldness, and bacterial, fungal, protozoan and viral infections. In one aspect, the invention relates to SDR2 polypeptides and recombinant materials and methods for their production. Another aspect of the invention relates to methods for using such SDR2 polypeptides and polynucleotides. Such uses include the treatment of cancer, inflammation, autoimmunity, allergy, asthma, rheumatoid arthritis, CNS inflammation, cerebellar

degeneration, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amylotrophic lateral sclerosis, head injury damage, and other neurological abnormalities, septic shock, sepsis, stroke, osteoporosis, osteoarthritis, ischemia reperfusion injury, cardiovascular disease, kidney disease, liver disease, ischemic injury, myocardial infarction, hypotension, hypertension, AIDS, myelodysplastic syndromes and other hematologic abnormalities, aplastic anemia, male pattern baldness, and bacterial, fungal, protozoan and viral infections, among others. In still another aspect, the invention relates to methods to identify agonists and antagonists using the materials provided by the invention, and treating conditions associated with SDR2 imbalance with the identified compounds. Yet another aspect of the invention relates to diagnostic assays for detecting diseases associated with inappropriate SDR2 activity or levels.

Method of treatment of Parkinsons's disease using phytic acid Inventor(s): Sabin; Robert (Goosedown Estate, Box 332, Horseshoe Rd., Mill Neck, Long Island, NY 11765) Assignee(s): none reported Patent Number: 5,206,226 Date filed: December 13, 1991 Abstract: A method is provided for treating Parkinson's Disease by administering to a subject an effective symptom-alleviating amount of a compound selected from the group consisting of phytic acid, phytate salt, an isomer or hydrolysate of phytic acid or phytate salt, or a mixture of any combination thereof. The preferred method of administration is by oral dosages of about 1/8 to 1/2 grams/kilogram bodyweight per day. Excerpt(s): The present invention is directed to a method for treating Parkinson's Disease by use of phytic acid, its salts or hydrolysates. Parkinson's disease is a progressive disorder that affects a small area of cells (called the substantia Nigra) in the middle part of the brain and which occurs slightly more often in men than women. It is also called Shaking palsy or paralysis agitans and is a disorder of the central nervous system primarily attacking people between the ages 50 and 69. Approximately one out of every 1,000 people contact the illness. A cause of Parkinson's disease is that the cells which normally produce dopamine, a chemical necessity for transmitting messages in the brain, degenerate and die causing a deficiency of dopamine and perhaps consequentially the symptoms of Parkinson's disease. The common symptoms include tremor, stiffness (or rigidity) of muscles, slowness of movement (bradykinesia) and loss of balance (postural dysfunction). Parkinson's disease is one of the most prevalent neurological conditions - along with epilepsy, stroke and dementia. The natural history of the disease results in a rate of progression from 10-15 years from onset of the disease, to disability, with some variability from patient to patient. Parkinson's itself, moreover, the disability caused by the disease often leads to fatal infections such as aspiration, pneumonia, and urinary tract infections. Parkinson's disease is usually categorized into three distinct groups. Paralysis agitans usually called Parkinson's disease is the most common form of Parkinsonism, afflicting approximately 75% of the cases and is of unknown origin or cause. The second type of Parkinsonism which is caused by drugs and toxins, which include carbon monoxide, manganese and chemical compound called MPTP (methyl-phenyltetrahydropyridine). The third form of Parkinsonism is called

Method to treat Parkinsons disease Inventor(s): Chiesi; Paolo (Parma, IT) Assignee(s): Chiesi Farmaceutici S.p.A. (Parma, IT) Patent Number: 5,017,607 Date filed: June 30, 1989 Abstract: Pharmaceutical compositions for the treatment of Parkinson's disease and neurologic syndromes connected with it, containing as the active principle levodopa methyl ester optionally combined with other active principles selected from dopaminergic, anticholinergic, antidepressive drugs, carboxylase and monoaminoxidase inhibitors. Excerpt(s): The present invention refers to pharmaceutical compositions for the treatment of Parkinson's disease, containing levodopa methyl ester alone or combined with other active principles. Parkinson's disease is characterized by a progressive degeneration of the dopaminergic nigrostriatal pathways in the brain. Biochemical studies carried out in the sixties lead to the discovery of the fundamental role played in the pathogenesis of this disease by the deficit of neurotransmitters, and particularly of dopamine.

Pharmaceutical compositions and method of producing anti-Parkinsonism activity Inventor(s): Kaiser; Carl (Haddon Heights, NJ), Pendleton; Robert G. (Philadelphia, PA), Setler; Paulette E. (Fort Washington, PA) Assignee(s): SmithKline Corporation (Philadelphia, PA) Patent Number: 4,052,506 Date filed: August 5, 1975 Abstract: Pharmaceutical compositions and method of producing anti-Parkinsonism activity by administering internally a nontoxic effective quantity of a benzazepine derivative to an animal. Excerpt(s): This invention relates to novel pharmaceutical compositions containing as an active ingredient compounds which have anti-parkinsonism activity and to a method of producing anti-parkinsonism activity by administering non-toxic effective quantities of said active ingredients to an animal. Parkinson's disease is a neurological disorder characterized by hypokinesia, akinesia, tremor and rigidity of the limbs. Parkinsonism is believed to be brought about by imbalance in the biochemical systems in the brain between the dopaminergic and cholinergic neural pathways. In patients suffering from parkinsonism, a depletion of dopamine in the brain is observed which is the result of progressive degeneration of nigro-striatal dopaminergic neurons. There is a great need for compounds and compositions which produce anti-parkinsonism activity without having limiting side effects. It is well known that L-dopa, a potential source of brain

194 Parkinson’s Disease

dopamine, has clinical utility in treating parkinsonism. L-Dopa is a precursor of dopamine, being decarboxylated in the brain, and thereby raising the levels of dopamine in patients who are deficient in it. However, L-Dopa does not qualify as an ideal compound in the treatment of parkinsonism due in part to its limiting side effects, such as, for example, nausea, emesis and anorexia.

Pharmaceutical preparation and method for treatment of parkinsonism Inventor(s): Nowak; Herbert (Darmstadt, DT), Seyfried; Christoph (Darmstadt, DT) Assignee(s): Merck Patent Gesellschaft mit beschrankter Haftung (Darmstadt, DT) Patent Number: 4,021,555 Date filed: December 16, 1975 Abstract: Administration of mepiprazole during L-dopa therapy for parkinsonism reduces undesired side effects of L-dopa and enhances the desired effects of L-dopa. Excerpt(s): This invention relates to a process for modifying the effects of therapeutic administration of L-dopa, and to pharmaceutical preparations suitable for this purpose. L-Dopa (L-3,4-dihydroxyphenylalanine) is used for the treatment of parkinsonism and Parkinson's disease. The cause of parkinsonism is thought to be a deficiency of the neurotransmitter dopamine, 2-(3,4-dihydroxyphenyl)-ethylamine, in the basal ganglia. Dopamine itself does not pass through the blood-brain barrier; for this reason, this compound is unsuitable for parkinsonism therapy. Consequently, treatment of parkinsonism is carried out by substitute therapy using high doses of L-dopa, a precursor of dopamine, which passes the blood-brain barrier. However, L-dopa is also a precursor of noradrenaline, so that its administration to a patient results in increased formation of noradrenaline. As a result, the metabolic equilibrium of the neurotransmitters noradrenaline and serotonin is disturbed in the brain. Administration of L-dopa also leads to reduction in the activity of serotoninergic neurons. The result is agitation, motoric unrest, increased sexuality, insomnia, hypomanic reactions, and sometimes even hallucinations and delirious conditions, i.e., "L-dopa psychosis". These psychic disturbances normally cannot be overcome by conventional psychopharmacological agents, which simultaneously counteract the effect of the dopamine so that symptoms of the original parkinsonism returns.

Treating central nervous system diseases Inventor(s): Aroonsakul; Chaovanee (6907 S. Constance, Chicago, IL 60649) Assignee(s): none reported Patent Number: 4,902,680 Date filed: January 3, 1989 Abstract: A method of treating humans suffering from central nervous system diseases, such as Alzheimer's disease, Parkinsons's disease, senile dementia. The treatment consists of inducing into the patient's blood stream at least one from the group consisting of: sex hormones and anabolic hormones. Growth hormone is also be used in those patients in advanced stages of the disease, or in those patients where it has been

Patents 195

determined that a low level of growth hormone is present. A method of diagnosing Alzheimer's disease, senile dementia, by the determination of the levels of the hormones somatotropin (human growth hormone) and somatomedin-C (IGF-I) after the administration of the Aroonsakul-Allen provocative test is also disclosed. Blood-sera samples are taken at certain time periods after the administration of L-Dopa, and the samples are tested for the levels of these hormones. These levels are then compared against the levels for normal subjects. Excerpt(s): The present invention is directed to a method of treatment for central nervous system diseases. These diseases for which the present inventive method has been found useful are: Alzheimer's disease; Parkinson's disease; senile dementia; essential tremor; senile tremor; and cerebellar atrophy and cerebral atrophy; multiple sclerosis; cerebrovascular accident. Each of these has been found to affect different portions of the brain. Alzheimer's disease affects the portion of the brain vital to memory retention, the cortex. Parkinson's disease is known to affect the nerve cells of the basal ganglia. Cerebellar atrophy is known to affect the nerve cells of the cerebellum. It has also been determined that in each of the above diseases, intrinsic depression develops, which is usually associated with an entirely different portion of the brain than those affected by the above-named diseases. It is also known that in each of these diseases characterized by biochemical lesions in enzymes, membranes, or structure proteins of particular components, cellular atrophy is the result, which is a slow process of cellular deterioration, sometimes deferred bes, but leading to cellular atrophy, and eventually resulting in serious functional loss, causing the symptoms associated with each of the diseases. Such cellular atrophy generally occurs with advancing age, but, owing to these diseases, the processes are somehow speeded up, in a manner not known or understood at the present time. What is certain, however, is that in any cellular breakdown, the enzymes required for protein synthesis are lacking. Further, it is also apparent that this lack of enzyme formation, and concomitant lack of protein synthesis, are caused by some interruption in the neural network through which biochemical signals are generated and transported. Thus, the very problem of each of these diseases runs to the basic structure of life: To wit, RNA and DNA, ribo nucleic acid and deoxyribonucleic acid, which program each cell to provide the necessary enzymes for life-sustaining activity. Heretofore, there has been no effective method of treatment of each of the above-named diseases. In the case of Parkinson's disease, L-Dopa has been employed and has achieved some success. However, the period of efficacy of L-Dopa is limited to a few months. In the case of Alzheimer's disease, and the remainder of the above-named diseases, ergoloid myselates have been used to some small success. The present invention is also directed to a method of diagnosing Alzheimer's Disease in human beings. Presently-used techniques for determining Alzheimer's disease include neuropsychological testing which compares the mental status of the patient relative to a norm, as well as the patient's cognitive dysfunction. Such testing also tests for mood depressions, agitation, irritability, and the like, all of which are symptoms of Alzheimer's disease. Other diagnostic tools and methods are: The use of a brain atlas beam test or EEG (electroencephalogram) which demonstrate increases in delta and theta waves. It is, of course, most important that a correct diagnosis be determined in order to decide upon the best treatment. The present invention is directed towards the incorporation of a novel diagnosis for Alzheimer's disease and senile dementia, that may be used in conjunction with other standard testing methods, or may be used alone for such determination, since this novel diagnosis has been found to be very accurate, especially when used in conjunction with conventional diagnostic tests for other chronic degenerative diseases of the CNS form which similar indications may result. It has been known that the drug levodopa (L-Dopa), a common drug for treating Parkinson's

196 Parkinson’s Disease

disease, causes increased secretion of the growth hormone somatotropin (HGH-human growth hormone). This finding of Aroonsakul and Allen provocative test (AA provocative test) such as L-Dopa's provocative stimulation of the pituitary gland to secrete HGH was used as the basis for viewing the functioning of the peripheral nervous system (PNS) as an aminergic neuronetwork. Furthermore, since the hormone somatomedin-C (often referred to as IGF-I, for insulin-like growth factor) is directly dependent upon the secretion of HGH by the pituitary gland, there has been established a direct linkage between increased secretion of HGH and increased production of the hormone somatomedin-C, which is produced chiefly in the liver and kidneys. The use of L-Dopa to markedly increase the secretions of somatotropin and, consequently, the production of somatomedin-C in the human body has led to what is generally termed the "L-Dopa provocative test". This test is used to determine the normal functioning of the anterior region of the pituitary gland responsible for the HGH production. Generally, the AA provocative test is used by detecting the increase of HGH and IGF-I in a blood serum by the use of radioimmunoassay (RIA), which determines the presence or absence or the amounts of a certain hormone in a serum by the use of a radioactive agent, used in vitro. RIA involves separation of the labelled antigen that is of interest into bound-unbound fractions after the interaction with an antibody in the presence of the unknown quantity of unlabelled antigen to be measured. The radioactive element used in this determination is usually I-125. Web site: http://www.delphion.com/details?pn=US04902680__ •

Treatment of Parkinsons disease Inventor(s): Owen; David A. A. (Welwyn Garden City, GB2) Assignee(s): Smith Kline & French Laboratories Limited (Welwyn Garden City, GB2) Patent Number: 4,824,860 Date filed: May 19, 1988 Abstract: The present invention relates to the use of certain indolone derivatives in particular, 4-(2-di-n-propyl-aminoethyl)-2-(3H)-indolone in a method of treatment of Parkinsons disease. Excerpt(s): The present invention relates to a method of treatment of disorders of the central nervous system, in particular Parkinsons Disease, by the administration of certain indolone derivatives. Parkinsons Disease is a disturbance of voluntary movement in which muscles become stiff and sluggish, movement becomes clumsy and difficult and uncontrollable rhythmic twitching of groups of muscles produces characteristic shaking or tremor. The condition is believed to be caused by a degeneration of pre-synaptic dopaminergic neurones in the brain. The absence of adequate release of the chemical transmitter dopamine during neuronal activity thereby leads to the Parkinsonian symptomatology. Currently, the most widely used treatment for Parkinsonism is administration of L-DOPA, a precursor of dopamine which acts indirectly by replacing the missing dopamine. However, disadvantages are associated with the use of L-DOPA, for example, patients often suffer from side-effects such as dyskinesia and on-off effects, and it is necessary to administer L-DOPA in conjunction with a peripheral dopa-decarboxylase inhibitor such as carbidopa or benzaseride. These inhibitors prevent the peripheral degradation of levodopa to dopamine, thus enabling more drug to enter the brain and limiting peripheral side-effects. Such treatment improves quality of life for patients but does not halt disease progression. Furthermore, such treatment is associated with a number of adverse effects including nausea,

vomiting, abdominal distension and psychiatric side-effects (for example, toxic confusional states, paranoia and hallucinations). Web site: http://www.delphion.com/details?pn=US04824860__ •

Use of combinations of L-DOPA with trazodone and L-DOPA with etoperidone in Parkinsonism Inventor(s): Silvestrini; Bruno (Rome, IT) Assignee(s): Aziende Chimiche Riunite Angelini Francesco A.C.R.A.F. S.p.A. (Rome, IT) Patent Number: 4,131,675 Date filed: February 9, 1978 Abstract: A combination of trazodone or etoperidone with L-DOPA is used in the treatment of Parkinsonism by oral administration to a patient. Excerpt(s): This invention concerns the use of combinations of L-DOPA with trazodone or L-DOPA with etoperidone in Parkinsonism in order to avoid the side effects of LDOPA resulting from stimulation of the adrenergic system and improve its therapeutic action. L-DOPA is extensively used in the therapy of Parkinsonism. Its use is based on the well known theory that Parkinsons disease and related conditions are produced by an imbalance between dopaminergic and cholinergic mechanisms at the nigrostriatal level. Parkinsonian symptoms appear when the cholinergic mechanism prevails over the dopaminergic one. Since L-DOPA is a precursor of dopamine and potentiates the adrenergic system, it readjusts the above mentioned imbalance thus leading to an improvement in Parkinsonism. See in this respect "The Pharmacological Basis of Therapeutics", L. S. Goodman and A. Gilman, Fourth Edition, The MacMillan Company, 1970, page 423. At the same time its administration produces side effects indicative of activation of the adrenergic system such as stimulation of the central nervous system, blood pressure and ECG changes, etc. Trazodone is the subject of U.S. Pat. No. 3,381,009 and Japanese Pat. No. 555,140 in which the drug's pharmacological and therapeutic properties are attributed to its tranquilizing, hypotensive and analgesic actions.

In addition to LOCATORPlus, in collaboration with authors and publishers, the National Center for Biotechnology Information (NCBI) is currently adapting biomedical books for the Web. The books may be accessed in two ways: (1) by searching directly using any search term or phrase (in the same way as the bibliographic database PubMed), or (2) by following the links to PubMed abstracts. Each PubMed abstract has a "Books" button that displays a facsimile of the abstract in which some phrases are hypertext links. These phrases are also found in the books available at NCBI. Click on hyperlinked results in the list of books in which the phrase is found. Currently, the majority of the links are between the books and PubMed. In the future, more links will be created between the books and other types of information, such as gene and protein sequences and macromolecular structures.

AAC for Huntington Disease and Parkinson's Disease: Planning for Change Source: in Beukelman, D.R.; Yorkston, K.M.; Reichle, J., eds. Augmentative and Alternative Communication for Adults with Acquired Neurologic Disorders. Baltimore, MD: Paul H. Brookes Publishing Co. 2000. p. 233-270. Contact: Available from Paul H. Brookes Publishing Co. P.O. Box 10624, Baltimore, MD 21285. (800) 638-3775. Fax (410) 337-8539. Website: www.brookespublishing.com. PRICE: $42.00 plus shipping and handling. ISBN: 1557664730. Summary: The loss of speech in adulthood due to acquired neurologic disorders causes a person to confront enormous life changes. This chapter on the use of augmentative and alternative communication (AAC) strategies for people with Huntington disease or Parkinson's disease is from a textbook that explores the challenges these adults face during their transition, whether gradual or immediate, from speaking to using AAC. This chapter focuses on movement disorders and their impact on communication; the daily experiences of people with these diseases and how the diseases can change their lives, their families' lives, and friends in their personal and community networks; and the use of AAC intervention at various stages of these diseases. Huntington disease is characterized by progressive motor disturbances, cognitive impairments, and psychological changes; these manifestations significantly affect the person's ability to communicate. Parkinson's disease is a slowly progressive movement disorder is characterized by an inability to execute learned motor movements; symptoms include resting tremor, rigidity, and slowness of movement. Communication disorders in Parkinson's are common, often beginning with a decrease in facial expression or

nonverbal gesture, at time progressing to decrease in vocal loudness, and later progressing to severe dysarthria characterized by changes in speaking rate, articulatory precision, and speech intelligibility. The authors conclude the chapter by offering models or frameworks for patient care delivery for these people. 105 references. •

ISBN: 1573926841. Summary: This book chapter discusses what is known about cognitive changes in Parkinson's disease through research and clinical observation, including the relationship between Parkinson's disease and dementia, and offers suggestions for dealing with these problems, including neurorehabilitation. Over 50 percent of Parkinson's disease patients suffer from measurable changes in cognition and there is a direct relationship between severity of the disease and the degree of cognitive dysfunction. Observations and findings are discussed in the areas of patient functioning in familiar versus unfamiliar activities, the ability to think quickly and fluidly, diminished visuospatial abilities, memory capacity, language-related abilities, and the comorbidity of Parkinson's disease with other forms of dementia such as Alzheimer's disease. Besides trying to maintain a sense of humor and a realistic outlook, caregivers are advised to have patience to allow Parkinson's patients time to formulate verbal responses or actions, provide memory aids wherever possible to increase the patient's self-reliance, and exercise caution when allowing patients to retain their driving privileges. Caregivers are further advised to seek more education about the disease, utilize Parkinson's disease support groups, and consider using Parkinson-specific exercise, nutrition, speech, and cognitive rehabilitation therapy programs.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.

U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for Parkinson’s disease. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with Parkinson’s disease. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.).

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.

Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.

PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.

Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to Parkinson’s disease by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “Parkinson’s disease” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for

Coffee Break: Tutorials for Biologists20 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.21 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.22 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.

Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •

CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.



Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.

The Genome Project and Parkinson’s Disease In the following section, we will discuss databases and references which relate to the Genome Project and Parkinson’s disease. Online Mendelian Inheritance in Man (OMIM) The Online Mendelian Inheritance in Man (OMIM) database is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. OMIM was developed for the World Wide Web by the National Center for Biotechnology Information (NCBI).23 The database contains textual information, pictures, and reference information. It also contains copious links to NCBI’s Entrez database of MEDLINE articles and sequence information. 20 Adapted 21

from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.

The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 22 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process. 23 Adapted from http://www.ncbi.nlm.nih.gov/. Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information--all for the better understanding of molecular processes affecting human health and disease.

236 Parkinson’s Disease

To search the database, go to http://www.ncbi.nlm.nih.gov/Omim/searchomim.html. Type “Parkinson’s disease” (or synonyms) into the search box, and click “Submit Search.” If too many results appear, you can narrow the search by adding the word “clinical.” Each report will have additional links to related research and databases. In particular, the option “Database Links” will search across technical databases that offer an abundance of information.

To access the Entrez system at the National Center for Biotechnology Information, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?CMD=search&DB=genome, and then select the database that you would like to search. The databases available are listed in the drop box next to “Search.” Enter “Parkinson’s disease” (or synonyms) into the search box and click “Go.” Jablonski’s Multiple Congenital Anomaly/Mental Retardation (MCA/MR) Syndromes Database24 This online resource has been developed to facilitate the identification and differentiation of syndromic entities. Special attention is given to the type of information that is usually limited or completely omitted in existing reference sources due to space limitations of the printed form. At http://www.nlm.nih.gov/mesh/jablonski/syndrome_toc/toc_a.html, you can search across syndromes using an alphabetical index. Search by keywords at http://www.nlm.nih.gov/mesh/jablonski/syndrome_db.html. The Genome Database25 Established at Johns Hopkins University in Baltimore, Maryland in 1990, the Genome Database (GDB) is the official central repository for genomic mapping data resulting from the Human Genome Initiative. In the spring of 1999, the Bioinformatics Supercomputing Centre (BiSC) at the Hospital for Sick Children in Toronto, Ontario assumed the management of GDB. The Human Genome Initiative is a worldwide research effort focusing on structural analysis of human DNA to determine the location and sequence of the estimated 100,000 human genes. In support of this project, GDB stores and curates data generated by researchers worldwide who are engaged in the mapping effort of the Human Genome Project (HGP). GDB’s mission is to provide scientists with an encyclopedia of the human genome which is continually revised and updated to reflect the current state of scientific knowledge. Although GDB has historically focused on gene mapping, its focus will broaden as the Genome Project moves from mapping to sequence, and finally, to functional analysis. To access the GDB, simply go to the following hyperlink: http://www.gdb.org/. Search “All Biological Data” by “Keyword.” Type “Parkinson’s disease” (or synonyms) into the search box, and review the results. If more than one word is used in the search box, then separate each one with the word “and” or “or” (using “or” might be useful when using synonyms).

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on Parkinson’s disease can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internetbased services that post them.

Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to Parkinson’s disease. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to Parkinson’s disease. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “Parkinson’s disease”:

Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on Parkinson’s disease. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

Oral Health Care and Parkinson's Disease Source: Staten Island, NY: American Parkinson Disease Association, Inc. (APDA). 1996. 4 p. Contact: Available from American Parkinson Disease Association, Inc. (APDA). 1250 Hylan Boulevard, Suite 4B, Staten Island, NY 10305. (718) 981-8001 or (800) 223-2732; Fax (718) 981-4399. PRICE: Single copy free. Summary: This fact sheet provides basic information about the oral health needs of people with Parkinson's disease (PD). The fact sheet first outlines some usual oral health findings in patients with PD. There is an increase in dental caries and in accumulation of dental plaque associated with increased gum inflammation and periodontal disease, overt tooth mobility, and pain. This is due to reduction of hand to mouth mobility in PD and in part the loss of toothbrushing skills. In addition, when patients wear removable partial and complete dentures for a long time, the fit is poor and usually there is a loss of bite stability. The fact sheet then outlines treatment options for these dental and oral health concerns. The remainder of the fact sheet addresses quality of life issues related to the need for dental care. These include disorders of swallowing, disorders of nutrition, disorders of language and speech communication, loss of self esteem, impairment of job and vocational function, and impairment of social and community communication. The fact sheet concludes with a few resource organizations through which readers can locate dentists familiar with PD.

The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to Parkinson’s disease. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

Parkinson's Disease Foundation, Inc Telephone: (212) 923-4700 Toll-free: (800) 457-6676 Fax: (212) 923-4778 Email: [email protected] Web Site: http://www.pdf.org Background: Parkinson s Disease Foundation, Inc., is a national not-for-profit organization dedicated to funding medical research to investigate the cause and cure of Parkinson s disease and related disorders. Established in 1957, the Foundation has a post-doctoral training program, offers extramural research grants, and makes referrals to physicians who treat Parkinson s disease. It strives to provide individuals with Parkinson's disease a better quality of life and, ultimately, find the cause and a cure. Other activities of the organization include counseling, supporting advocacy efforts, and providing referrals to self-help groups. In addition, the Foundation has a Research Advisory Board composed of internationally known neurological scientists. The Parkinson s Disease Foundation conducts symposia and distributes a variety of educational materials including brochures, booklets, a manual for health care professionals, and a regular newsletter. Relevant area(s) of interest: Parkinson's Disease

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to Parkinson’s disease. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with Parkinson’s disease. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about Parkinson’s disease. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations.

The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “Parkinson’s disease” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “Parkinson’s disease”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “Parkinson’s disease” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “Parkinson’s disease” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.

Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.26

Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.

Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

PARKINSON’S DISEASE DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine: A dopaminergic neurotoxic compound which produces irreversible clinical, chemical, and pathological alterations that mimic those found in Parkinson disease. [NIH] Abdomen: That portion of the body that lies between the thorax and the pelvis. [NIH] Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Aberrant: Wandering or deviating from the usual or normal course. [EU] Ablation: The removal of an organ by surgery. [NIH] Acceptor: A substance which, while normally not oxidized by oxygen or reduced by hydrogen, can be oxidized or reduced in presence of a substance which is itself undergoing oxidation or reduction. [NIH] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Acidity: The quality of being acid or sour; containing acid (hydrogen ions). [EU] Acoustic: Having to do with sound or hearing. [NIH] Actin: Essential component of the cell skeleton. [NIH] Activities of Daily Living: The performance of the basic activities of self care, such as dressing, ambulation, eating, etc., in rehabilitation. [NIH] Adaptability: Ability to develop some form of tolerance to conditions extremely different from those under which a living organism evolved. [NIH] Adaptation: 1. The adjustment of an organism to its environment, or the process by which it enhances such fitness. 2. The normal ability of the eye to adjust itself to variations in the intensity of light; the adjustment to such variations. 3. The decline in the frequency of firing of a neuron, particularly of a receptor, under conditions of constant stimulation. 4. In dentistry, (a) the proper fitting of a denture, (b) the degree of proximity and interlocking of restorative material to a tooth preparation, (c) the exact adjustment of bands to teeth. 5. In microbiology, the adjustment of bacterial physiology to a new environment. [EU] Adenine: A purine base and a fundamental unit of adenine nucleotides. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Adenosine Triphosphate: Adenosine 5'-(tetrahydrogen triphosphate). An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter. [NIH] Adenovirus: A group of viruses that cause respiratory tract and eye infections.

262 Parkinson’s Disease

Adenoviruses used in gene therapy are altered to carry a specific tumor-fighting gene. [NIH] Adjunctive Therapy: Another treatment used together with the primary treatment. Its purpose is to assist the primary treatment. [NIH] Adjustment: The dynamic process wherein the thoughts, feelings, behavior, and biophysiological mechanisms of the individual continually change to adjust to the environment. [NIH] Adjuvant: A substance which aids another, such as an auxiliary remedy; in immunology, nonspecific stimulator (e.g., BCG vaccine) of the immune response. [EU] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU] Adverse Effect: An unwanted side effect of treatment. [NIH] Aerobic: In biochemistry, reactions that need oxygen to happen or happen when oxygen is present. [NIH] Aerobic Metabolism: A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also known as aerobic respiration, oxidative metabolism, or cell respiration. [NIH] Aerobic Respiration: A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also known as oxidative metabolism, cell respiration, or aerobic metabolism. [NIH] Afferent: Concerned with the transmission of neural impulse toward the central part of the nervous system. [NIH] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. In immunology, a thermodynamic expression of the strength of interaction between a single antigen-binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole -1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean intrinsic association constant). 6. The reciprocal of the dissociation constant. [EU] Agar: A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis. [NIH]

Age of Onset: The age or period of life at which a disease or the initial symptoms or manifestations of a disease appear in an individual. [NIH] Aggravation: An increasing in seriousness or severity; an act or circumstance that intensifies, or makes worse. [EU] Agonist: In anatomy, a prime mover. In pharmacology, a drug that has affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances. [EU] AK: Enzyme of the biosynthetic pathway. [NIH] Akathisia: 1. A condition of motor restlessness in which there is a feeling of muscular

Dictionary 263

quivering, an urge to move about constantly, and an inability to sit still, a common extrapyramidal side effect of neuroleptic drugs. 2. An inability to sit down because of intense anxiety at the thought of doing so. [EU] Akinesia: 1. Absence or poverty of movements. 2. The temporary paralysis of a muscle by the injection of procaine. [EU] Alertness: A state of readiness to detect and respond to certain specified small changes occurring at random intervals in the environment. [NIH] Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task. [NIH] Alkaloid: A member of a large group of chemicals that are made by plants and have nitrogen in them. Some alkaloids have been shown to work against cancer. [NIH] Alleles: Mutually exclusive forms of the same gene, occupying the same locus on homologous chromosomes, and governing the same biochemical and developmental process. [NIH] Alpha Particles: Positively charged particles composed of two protons and two neutrons, i.e., helium nuclei, emitted during disintegration of very heavy isotopes; a beam of alpha particles or an alpha ray has very strong ionizing power, but weak penetrability. [NIH] Alternative medicine: Practices not generally recognized by the medical community as standard or conventional medical approaches and used instead of standard treatments. Alternative medicine includes the taking of dietary supplements, megadose vitamins, and herbal preparations; the drinking of special teas; and practices such as massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Alternative Splicing: A process whereby multiple protein isoforms are generated from a single gene. Alternative splicing involves the splicing together of nonconsecutive exons during the processing of some, but not all, transcripts of the gene. Thus a particular exon may be connected to any one of several alternative exons to form messenger RNA. The alternative forms produce proteins in which one part is common while the other part is different. [NIH] Amantadine: An antiviral that is used in the prophylactic or symptomatic treatment of Influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The mechanisms of its effects in movement disorders are not well understood but probably reflect an increase in synthesis and release of dopamine, with perhaps some inhibition of dopamine uptake. [NIH] Ameliorating: A changeable condition which prevents the consequence of a failure or accident from becoming as bad as it otherwise would. [NIH] Amenorrhea: Absence of menstruation.

[NIH] Compacta: Part of substantia nigra. [NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
