Active clinical trials for "Parkinson Disease"

Aim: To determine the Responsiveness of the iMOBILITY in response to intensive physical therapy exercise programs. (Is it sensitive to change?) Although exercise is thought to be the most effective intervention for balance and gait in PD (compared to dopaminergic medication or DBS surgery), the best exercise program for mobility in PD is unknown. The iMOBILITY will be used to quantify balance and gait performance before and after two PT-supervised, intensive, exercise programs, expected to improve balance and gait. The first program is a published Treadmill training program and the second is the investigators new Agility training program with sensorimotor progressions, targeted at specific impairments that underlie the abnormalities of balance and gait in PD (developed for the Kinetics Foundation). This pilot clinical trial will randomize 40 PD subjects into the two exercise programs at OHSU in preparation for a larger clinical trial to determine the most effective exercise for mobility disability in PD. The effects of exercise will be compared with no treatment during a 5-week delay prior to start of exercise. This trial will also determine the relative responsiveness (compared to traditional clinical scales) of the iMOBILITY for testing the hypothesis that intensive exercise can improve mobility in PD. We will use existing instruments (Berg Balance Scale, BEST of dynamic balance, UPDRS, PDQ-39, 5 times sit-to-stand time and the Functional Performance Battery) to show there is a difference between the exercise groups. Superior responsiveness of the iMOBILITY system will be determined by larger differences with exercise intervention with the iMOBILITY system than with traditional clinical measures of mobility in PD.

The purpose of this study is to determine the long term safety and clinical utility of IPX066 in subjects with Parkinson's Disease.

This is a study of the efficacy and safety of preladenant in adult participants with moderate to severe Parkinson's Disease (PD). While on this study, participants will continue to take their usual, prescribed, stable regimen of levodopa (L-dopa) or L-dopa plus adjunct PD medications and will be randomized to receive 2 mg preladenant, 5 mg preladenant, or placebo, twice daily, for 12 weeks. After that, participants may choose to receive additional treatment with preladenant. The primary hypothesis is that at least the 5 mg twice daily dose of preladenant is superior to placebo as measured by the change from Baseline to Week 12 in the mean "off" time.

The purpose of the research study is to determine if rasagiline is an effective treatment for fatigue in patients with Parkinson's disease (PD).

This study will be carried out to determine the effectiveness of in-home computer games played by a person with Parkinson's disease for 50 minutes 3 times a week on measures of standing and walking balance.

This is a phase III, multicenter, randomized, double-blind, parallel group, placebo-controlled study to compare the efficacy of 6-months therapy of ropinirole Prolonged Release (PR) with that of placebo as adjunctive therapy to L-dopa in Parkinson's disease patients not optimally controlled on L-dopa. This study will be conducted in China. Subjects will have total 14 visits over the 26 week duration of the study. Following screening, eligible subjects will receive study medication during the fourteen day placebo run-in period which they will be instructed to take in addition to their background L-dopa. If subjects are still eligible at the end of the placebo run-in period they will be randomized (1:1) to receive once daily doses of ropinirole PR or identical appearing placebo tablets. Dosing will start at 2 mg ropinirole PR, or placebo equivalent. During the 24 week treatment phase, the subjects dose will be adjusted according to the recommended schedule to achieve symptomatic control. All subjects must be titrated to a minimum dose of 6 mg/day. If sufficient symptomatic control is not achieved or maintained at a dose of 6mg/day of ropinirole PR, the daily dose should be increased by 2mg at weekly or longer intervals up to a dose of 8mg/day.If sufficient symptomatic control is still not achieved or maintained at a dose of 8mg/day of ropinirole PR, the daily dose should be increased by 4mg at two weekly or longer intervals. Further dose titration should not be conducted within the final 8 weeks of the treatment phase. The maximum recommended daily dose is 24mg. The planned reduction in L-dopa dose will begin once subjects are titrated to Dose Level 4 or Dose Level 5 of study medication. For each increase in study medication, there will be a corresponding decrease in L-dopa. If loss of symptom control occurs with the reduction in the background L-dopa dose, the dose of study medication should be increased to the next higher dose level with no adjustment in the dose of L-dopa. If loss of symptom control persists, subjects should be titrated up an additional dose level. Subjects who do not experience an improvement in symptoms following upward titration by 2 dose levels of study medication, should be "rescued" with L-dopa. Subjects will be dispensed down-titration medication at the study completion/early withdrawal visit if the patient did not enter extension study and should be scheduled to return for a follow up visit 4 to 14 days after the last dose of study medication. The extension study aim to evaluate the safety profile of ReQuip PR during long-term treatment in subjects with advanced parkinson's disease.

This study will evaluate the safety and efficacy of administration of AFQ056 in combination with L-dopa, in reducing the number of L-dopa related dyskinesias in Parkinson's disease patients.

This study evaluated the pharmacokinetics, motor effects, and assessed the safety of IPX066 compared with an immediate-release cabridopa-levodopa formulation in subjects with advanced Parkinson's disease.

Phytopharm plc is developing Cogane™ which is a new medicine for the treatment of Parkinson's disease (PD). The purpose of the study is to find out if Cogane is safe and well tolerated in both healthy volunteers and Parkinson's disease patients and to determine if there is a difference in the way that the body deals with Cogane (pharmacokinetics) between these two groups. It is expected that the study will prove that Cogane™ is safe and well tolerated and will provide us with a pharmacokinetic profile for both subject groups.

The objective of this open-label extension is to assess the safety and tolerability of long-term treatment of the rotigotine patch in subjects with early-stage idiopathic Parkinson's disease.
