DALI
Start date: July 2003

Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine whether treatment of H. pylori (an infection of the stomach) improves treatment effectiveness in patients with Parkinson's disease and motor fluctuations.

NCT ID: NCT00656253 Completed - Parkinson's Disease Clinical Trials

Clinical Trial on the Effectiveness of Herbal Medicinal Mixture in Parkinson Disease

Start date: August 2008
Phase: Phase 2/Phase 3
Study type: Interventional

This study was designed to evaluate the symptomatic effects or potential disease progression slowing down effect of a kind of Herbal Medicinal Mixture in Parkinson's disease (PD) patients. The treatment phase includes 12 months period of Herbal Medicinal Mixture per day or placebo and 1 month wash-out period without herbal medicine and placebo.

NCT ID: NCT00646204 Completed - Parkinson's Disease Clinical Trials

Namenda (Memantine) for Non-motor Symptoms in Parkinson's Disease

Start date: April 2006
Phase: Phase 4
Study type: Interventional

To evaluate the effects of Memantine on non-motor symptoms in patients with Parkinson's disease. Parkinson's disease (PD) affects about one million people in the United States. It is a common neurological condition that is clinically defined by rigidity (muscle stiffness), bradykinesia (slowness of movement) and tremor. Parkinson's Disease , however, reveals numerous non-motor symptoms that have been underemphasized. Problematic symptoms include varying degrees of dementia, psychosis, diminished assertiveness and confidence, general fatigue, excessive daytime sleepiness, problems with blood pressure, sweating, and bladder, and a common yet difficult to define sense of "not feeling well".

NCT ID: NCT00643890 Terminated - Parkinson's Disease Clinical Trials

Study of AAV-GAD Gene Transfer Into the Subthalamic Nucleus for Parkinson's Disease

Start date: August 2008
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the safety and efficacy of AAV-GAD gene transfer into the subthalamic nucleus (STN) region of the brain. This study involves the treatment of subjects with medically refractory Parkinson's disease (PD). The gene transfer product, a disabled virus with a gene called GAD, will be infused into the STN bilaterally using stereotactic surgical techniques. The overall goal of this approach is to normalize the activity of the STN and reduce the motor symptoms of PD. Because the change in UPDRS demonstrated a positive outcome, the sham surgery subjects from the blinded portion of the study will be invited to crossover into the Open-label Arm portion of the study. The Open-label Arm will further evaluate the safety and efficacy of AAV-GAD gene transfer into the subthalamic nucleus (STN) region of the brain.

NCT ID: NCT00642928 Completed - Parkinson's Disease Clinical Trials

Dose Range Finding Study of BF2.649 Versus Placebo to Treat Excessive Daytime Sleepiness in Parkinson's Disease Patients

Start date: October 2007
Phase: Phase 2
Study type: Interventional

The objective of this trial is to define the minimum effective dose of BF 2.649 between 5 mg, 10 mg, 20 mg or 40 mg versus placebo in reducing the Excessive Daytime Sleepiness of Parkinson's disease patients

NCT ID: NCT00642889 Completed - Parkinson's Disease Clinical Trials

Safinamide as Add-On Therapy in Patients With Early Idiopathic Parkinson's Disease Treated With a Stable Dose of a Single Dopamine Agonist (12 Month Extension)

Start date: June 2005
Phase: Phase 3
Study type: Interventional

To determine the long-term safety and efficacy of a dose range of safinamide of 50-200 mg/day, p.o., compared to placebo, as add-on therapy in patients with early idiopathic Parkinson's disease who are currently receiving a stable dose of a single dopamine (DA) agonist.

NCT ID: NCT00642356 Terminated - Parkinson's Disease Clinical Trials

Carbidopa/Levodopa/Entacapone Versus Immediate Release (IR) Carbidopa/Levodopa on Non-motor Symptoms in Patients With Idiopathic Parkinson's Disease and Demonstrating Non-motor Symptoms of Wearing Off

Start date: March 2008
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT00640952 Withdrawn - Parkinson's Disease Clinical Trials

Acamprosate for Treatment of Compulsive Behaviors and Craving in Parkinson's Disease

Start date: August 2006
Phase: N/A
Study type: Interventional

The purpose of this study is to determine how many patients with Parkinson's disease have compulsive behaviors, and what types of behaviors they have. This study will also determine if acamprosate can be used to treat compulsive behaviors in Parkinson's disease patients.

NCT ID: NCT00640159 Completed - Parkinson's Disease Clinical Trials

Selegiline to Zelapar Switch Study in Parkinson Disease Patients

Start date: January 2007
Phase: Phase 4
Study type: Interventional

Parkinson's disease (PD) is a progressive neurodegenerative disease. Symptomatic therapy is primarily aimed at restoring dopamine function in the brain. Oral selegiline in conjunction with L-dopa has been a mainstay of therapy for PD patients experiencing motor fluctuations for many years. The mechanisms accounting for selegiline's beneficial adjunctive action in the treatment of PD are not fully understood. Inhibition of monoamine oxidase (MAO) type B (MAO-B) activity is generally considered to be of primary importance. Oral selegiline has low bio-availability and is typically dosed BID, for a total of 5-10 mg daily. Recently, the FDA approved a new orally disintegration tablet (ODT) formulation of selegiline, called ZelaparTM. This new formulation utilizes Zydis technology to dissolve in the mouth, with absorption through the oral mucosa, thereby largely bypassing the gut and avoiding first pass hepatic metabolism. This allows more active drug to be delivered at a lower dose. Consequently, Zelapar is dosed once-daily, up to 2.5 mg per day. There are no empirical data indicating whether the use of the new approved formulation of selegiline ODT (Zelapar) is superior or preferred by patients compared to traditional oral selegiline. It is believed that clinical efficacy will be preserved or enhanced, by delivering more active drug, with improved patient preference for the ODT formulation due to the once-daily dosing . The effectiveness of orally disintegrating selegiline as an adjunct to carbidopa/levodopa in the treatment of PD was established in a multicenter randomized placebo-controlled trial (n=140; 94 received orally disintegrating selegiline, 46 received placebo) of three months' duration. Patients randomized to orally disintegrating selegiline received a daily dose of 1.25 mg for the first 6 weeks and a daily dose of 2.5 mg for the last 6 weeks. Patients were all treated with levodopa and could additionally have been on dopamine agonists, anticholinergics, amantadine, or any combination of these during the trial. At 12 weeks, orally disintegrating selegiline-treated patients had an average of 2.2 hours per day less "OFF" time compared to baseline. Placebo treated patients had 0.6 hours per day less "OFF" time compared to baseline. These differences were significant (p < 0.001). Adverse events were very similar between drug and placebo.
