NCT00627640
Parkinson's Disease is a major neurodegenerative disorder in which there is a progressive loss of dopamine-containing neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO-B, the major DA metabolising enzyme in man. Safinamide is an inhibitor of MAO-B. This is a phase III trial to evaluate the efficacy and safety of safinamide (50 and 100 mg p.o. q.a.m.) compared to placebo as add-on therapy to a stable dose to levodopa in subjects with advance idiopathic Parkinson's Disease. The principal efficacy measure is the increase in mean daily "on" time during the 18-hr diary recording period.
NCT00086190
The purpose of this study is to find out if two antidepressant medications, paroxetine and venlafaxine, can help control depression in Parkinson's disease, and if these medications affect the motor symptoms of Parkinson's disease such as tremor, stiffness, slowness, and balance.
NCT00040404
The purpose of this study is to establish safety for CEP-1347 and to determine an efficacious dose in the treatment of Parkinson's disease.
NCT00407212
This study will investigate the effect of TCH346 compared to placebo in delaying the need for symptomatic treatment with dopaminergic agents
NCT00817453
Purpose: 1. To see if cytokine levels and oligomeric alpha-synuclein levels in blood and cerebrospinal fluid could be used as biological markers for Parkinson's disease (PD) onset and progression. 2. To characterize and define patterns in the clinical features of sleep, olfactory function and motor function in the early stages of idiopathic (sporadic) Parkinson's disease (PD)and atypical or late Parkinsonian Syndromes. Procedures: All subjects, control,early PD diagnosis and atypical or late Parkinsonian Syndromes, will have 1) a medical and neuro history and physical including videotaping of movements, 2) neuropsychological testing, 3) a sleep study, 4) olfactory (sense of smell) testing, 5)blood draw and LP for serum and CSF testing, \& 6) functional MRI. All of these procedures are often done in the diagnosis of PD. Any test performed prior to enrollment as part of the clinical evaluation may be used in place of repeating the procedure. Subjects will have 1 set of study visits (up to 3 visits) in order to accomplish a complete set of data.
NCT00642356
The purpose of this study is to test the effects of carbidopa/levodopa/entacapone compared to the effects of immediate-release carbidopa/levodopa on non-motor symptoms of end-of-dose wearing off in persons who have Parkinson's disease.
NCT00407095
This study is a multicenter, 9 months, open label extension study for all patients who are willing and eligible to continue from the pivotal, double-blind S308.3.002 study.
NCT00203034
Study for patients currently using Levodopa/Carbidopa who will be assigned to receive either Rasagiline or Placebo
NCT00559871
The purpose of this study is to determine whether Fipamezole is effective in the treatment of levodopa-induced dyskinesia in advanced Parkinson's disease.
NCT00100438
This is a database study. Medical records will be reviewed in order to document a new or pending diagnosis of Parkinson's disease and in order to learn more about the disease process. Other than the time that it takes to complete a medical record authorization form, no other human subject participation will be needed.
NCT00269516
This study is a multicenter, randomized, double blind, parallel group study of 6 months' treatment with SLV308 administered as a monotherapy in patients with early stage PD. An open label safety extension to this study is planned as a separate protocol for patients who are willing and eligible to participate.
NCT00605163
The purpose of this study is to longitudinally follow consenting clinical trial participants who participated in PRECEPT (A Randomized, Double Blind, Placebo Controlled, Dose Finding Study to Assess the Efficacy and Safety of CEP 1347 in Patients With Early Parkinson's Disease). The study will assess the clinical and imaging outcomes relevant to the natural history of Parkinson's disease (PD), as well as determine early biomarkers of the disease.
NCT00427011
Phase IIb open-label extension study for patients with Parkinson's Disease. All patients will receive active study drug. The study will involve outpatient visits only. Patients who completed Study E2007-A001-214 (Cohorts I and II) and who meet inclusion/exclusion criteria will be enrolled and enter the 12-week Titration Phase (from "Dispense Study Drug" at Week 0 \[Visit 2\] through Week 12 \[Visit 7\]) followed by the Maintenance Phase (from Week 12 \[Visit 7\] to end of study).
NCT00909545
The primary purpose of this study is to establish a dosage of isradipine CR that is tolerable and demonstrates preliminary efficacy for utilization in future pivotal efficacy studies.
NCT00096720
Study participants who have been clinically diagnosed with Parkinson disease will receive no treatment, treatment with either levodopa, or treatment with Mirapex for a period of 12 weeks. Over the course of the study subjects will travel to the Institute for Neurodegenerative Disorders (IND) in New Haven, Connecticut for brain imaging.
NCT00335374
This is a multicenter, 6 months open label safety extension study for all patients who are willing and eligible to continue from the pivotal, double-blind S308.3.003 trial
NCT00335166
This is a multicenter, randomized, double blind, parallel group study of 6 months' treatment with SLV308 as monotherapy in patients with early stage PD. An open label safety extension to this study is planned as a separate protocol for patients who are willing and eligible to participate.
NCT00087542
The primary objective is to demonstrate that the investigational new drug, ACP-103, is well tolerated by, and will not worsen parkinsonism in, patients with Parkinson's disease and psychosis. The secondary objectives are to determine whether ACP-103 will ameliorate psychosis in patients with Parkinson's disease and whether ACP-103 is safe in Parkinson's disease patients taking multiple anti-parkinsonian medications.
