NCT00605683
Parkinson's disease is a major neurodegenerative disorder in which there is a progressive loss of nigrostriatal dopaminergic 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. This is a double-blind, placebo-controlled, parallel-group, randomised, multi-centre, multi national, Phase III trial, comparing two doses of safinamide (50 and 100 mg p.o. q.a.m.) versus placebo as add-on therapy to a stable dose of a single dopamine agonist in subjects with early idiopathic Parkinson's Disease. The principal efficacy measure, i.e., change in mean value of UPDRS - Section III total score from baseline to endpoint, was chosen based on regulatory guidance and prior use in other trials in similar populations.
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.
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
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.
NCT00217321
The purpose of the Parkinson's disease Registry is to develop a national and international database of persons with Parkinson's disease (PD). The Registry will be used to facilitate the development of new therapies and healthcare services to improve the quality of life for people with PD. It will also be a means for investigators in the field of PD to quickly identify and notify subjects about other research studies for which they are eligible. Objectives include: * Assess current treatment approaches and develop best-practice guidelines * Track the functional abilities, access to healthcare and cost of illness of people with PD over time * Drive the development of innovative research projects * Accelerate the process of informing patients of research projects for which they may be eligible
NCT00617019
The purpose is to explore the frequency of impulse control disorders in Parkinson's patients treated with different Parkinson's medications.
NCT00148486
To demonstrate efficacy and dose-response of NS 2330 versus placebo in patients with early Parkinson's Disease in 14 weeks of treatment, and to investigate the safety and tolerability of NS 2330 in these patients.
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).
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.
NCT00043849
The primary aim of this study is to determine the safety and efficacy of quetiapine (Seroquel) for the treatment of psychosis and/or agitation in patients with primary dementia complicated by coexistent parkinsonism, or patients with Parkinson's disease with dementia \[PDD\] who have episodes of agitation or psychosis. The secondary aim is to determine the safety and tolerability, particularly the influence on parkinsonism, of quetiapine when used to treat psychosis and/or agitation in patients with dementia complicated by coexistent parkinsonism.
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.
NCT01515410
The primary objective of this study is to explore the efficacy and tolerability of DM-1992 compared to a standard carbidopa/Levodopa Immediate-Release (CD/LD IR) tablet (Sinemet IR) as measured by: * "ON" time with no dyskinesia or non-troublesome dyskinesia * "OFF" time
NCT01603069
This is a study where AZD3241 or placebo is given to patients with Parkinson's disease in a blinded and randomized assignment. The main objective is to see if safety and tolerability of the drug is acceptable.
NCT01140841
The purpose of this clinical trial is to determine the maximum tolerated dose of Fipamezole in adult patients with Parkinson's disease who are receiving levodopa.
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.
NCT00203177
Study to look at the effectiveness, tolerability and safety of two doses of Rasagiline (0.5 mg and 1mg) in advanced Parkinson's Disease (PD) Patients who have been treated with Levodopa/Carbidopa therapy.
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.
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.
NCT01536821
The PROGENI Family Study is part of a larger consortium that is studying a gene shown to be important in Parkinson's disease, called LRRK2. People who have a defect in the LRRK2 gene will often develop Parkinson's disease. Eligible participants will be asked to complete a single Study Visit at an affiliated research facility closest to their home.
