Active clinical trials for "Parkinson Disease"

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

To investigate the effect of repeated dosing of BIA 9-1067 on the levodopa pharmacokinetics, in comparison to placebo and entacapone.

This is a multi-center, double-blind, placebo controlled clinical trial of two dosages of oral pioglitazone (15 milligram(mg) and 45 milligram (mg)) for safety, tolerability, and futility. Subjects who are on stable dose of rasagiline 1 mg/day or selegiline 10 mg/day for at least 8 weeks but no more than 8 months, will be randomized to one of two dosages of oral pioglitazone (15 mg and 45 mg) or matching placebo. The study will measure disease progression by the change in total Unified Parkinson's Disease Rating Scale (UPDRS) score between the baseline visit and 44 weeks.

The goal of this multicentric prospective randomized controlled clinical and economic study is to investigate the effectiveness and cost-utility of long-term continuous intraduodenal infusion of levodopa ( DUODOPA), compared to best medical treatment, on advanced and severe form of Parkinson's disease.

While Parkinson's disease has historically been defined in terms of its motor symptomatology, studies have shown that non-motor deficits form an important part of the syndrome. Cognitive deficits can occur even in the early stages of Parkinson's disease. These deficits are often subtle and do not rise to the level of impairment necessary for a diagnosis of dementia; however these deficits are discernable with neuropsychological testing and may produce subjective complaints of cognitive decline and mild functional difficulties in some patients. The traditional pharmacological interventions for Parkinson's disease have focused on controlling and alleviating motor symptoms with levodopa and dopamine agonists. However, these medications treat the symptoms of PD, but do not alter the course or progression of the underlying disorder. In contrast, rasagiline, an MAO-B inhibitor, has recently shown benefits consistent with a possible disease-modifying effect. Given the positive and intriguing findings seen with treatment with rasagiline, the investigators propose to study the effects of this medication on cognition in patients with mild to moderate stage Parkinson's disease. Hypotheses: Rasagiline will improve cognitive function, as measured by performance on neuropsychological tests in PD patients who do not suffer from dementia. Rasagiline will not negatively affect neuropsychiatric functioning.

Study objectives are to determine the efficacy, safety and tolerability of bright light treatment in Parkinson's Disease (PD) patients with daytime sleepiness. Thirty PD patients will be enrolled and equally randomized to bright light or dim-red light treatment. Objective (actigraphy) and subjective (sleep logs/scales) sleep measures will be collected through the baseline and intervention phases of the study. The primary outcome measure will be the change in the Epworth Sleepiness Scale (ESS) comparing the bright light treatment with dim-red light treatment. Secondary outcome measures will include the Multiple Sleep Latency Test (MSLT), global Pittsburgh Sleep Quality Index (PSQI) score, Parkinson's Disease Sleep Scale (PDSS) score, and actigraphy measures. A variety of exploratory analyses will examine the effects of bright light treatment on fatigue, depression, quality of life, cognition, and motor disability. Hypothesis: Bright light exposure will diminish daytime sleepiness and improve night-time sleep in PD patients with daytime sleepiness.

The purpose of this study is to fulfil regulatory requirements for registration of a new chemical entity in China. Rasagiline is approved for the treatment of Parkinson's Disease (PD) in Europe and the US. Rasagiline is safe and well tolerated in healthy subjects, and the efficacy and safety has been demonstrated in placebo- and active comparator-controlled phase III studies.

The purpose of this study is to assess the safety and feasibility of switching subjects with advanced Parkinson's Disease (PD) from Pramipexole or Ropinirole to Rotigotine and to assess the effects of Rotigotine on motor and non-motor symptoms of Parkinson's Disease in subjects switched from previous treatment with either Pramipexole or Ropinirole.

The primary objective of this study is to investigate efficacy and safety of SPM 962 in advanced Parkinson's Disease (PD) patients in a multi-center, placebo-controlled study following once-daily multiple transdermal doses of SPM 962 within a range of 4.5 to 36.0 mg (12 weeks of dose titration/maintenance period). Recommended maintenance dose range is also to be investigated with distribution of the maintenance dose and accumulated response rate of efficacy.

The purpose of this study is to determine whether performing deep brain stimulation surgery for Parkinson's disease using intraoperative imaging and frameless stereotaxis is noninferior to using frame-based stereotaxy and microelectrode recording.
