Filter by:Patients will be randomised to receive either placebo or the study drug for a period of 30 weeks, in addition to their standard Parkinsonian medications. During the first 8 weeks, the patient's levodopa doses may be adjusted if necessary by the investigator. For the remainder of the 22 weeks, all medications should be kept stable. Patients will be required to attend the clinic twice during the screening period and then a further 8 times during the treatment period. They will be required to complete home diaries where they will record their motor function. In addition, their doctor will assess their Parkinson's disease during the clinic visits. There will also be blood draws for safety and pharmacokinetic and pharmacogenomics evaluation. Following the treatment and assessment period, they will return to the clinic one month later for follow up.
B-STN DBS is one of the most effective surgical treatments for PD patients suffering from levodopa-induced motor complications. The relatively low incidence of permanent adverse effects and the potential for neuroprotection and alteration of the natural course of PD suggest a highly favorable benefit-to-risk ratio of this procedure. Since neuroprotection is best applied early in the disease course when there are more surviving neurons, we believe that further investigation of this procedure is warranted. The proposed pilot study will provide the necessary data to substantiate the safety and tolerability of the procedure as well as provide data for the design of a full-scale, multicenter trial to investigate the hypothesis that B-STN DBS is a safe and effective treatment to slow the progression of PD.
A 2 phase study to evaluate disease progression in Parkinson's disease patients taking rasagiline
The purpose of this study is to compare the clinical efficacy of IPX054 to immediate-release carbidopa-levodopa in subjects with Parkinson's disease.
This is a Phase I dose escalating open-label study designed to assess the safety, tolerability and biologic activity of an in vivo AAV2 mediated delivery of the gene encoding NTN (CERE-120). Twelve (up to 18) subjects will receive one of two open-label doses of CERE-120 via bilateral stereotactic injections targeting the putaminal region of the brain. Subjects will be enrolled in one of two cohorts, a low-dose cohort of six subjects followed by a high dose cohort of six subjects. The design of this study is such that the primary objective, the evaluation of safety and tolerability, will be assessed by frequent observations for adverse events, clinical laboratory test results, imaging (MRI), neuropsychometric testing, and evaluations of disease status.
To establish the efficacy of 40 mg/day doses of istradefylline for the change in Unified Parkinson's Disease Rating Scale (UPDRS) part-III (Motor examination) score in patients with Parkinson's disease (PD).
Multi-centre, randomised, parallel-group study, rater-blinded. Total duration of the study per subject is 12 weeks plus a one- to two-week screening period. There are 6 pre-planned visits per subject: screening visit followed by 5 visits. Approximately 300 patients altogether in up to 25 active German study centres and up to 3 active Lithuanian study centres will be randomised.
To test if combining two antiparkinson drugs into a single tablet improves accuracy of medicine intake by the patient. To test if patients with Parkinson's disease who take medicines at regular time intervals have smoother symptom control.
The objective of this trial is to compare the effect of rotigotine (SPM 962) and ropinirole on the control of early morning motor impairment and sleep disorders in subjects with early-stage PD. Subjects who meet eligibility criteria will be randomly assigned either to rotigotine transdermal patch or ropinirole tablets. Trial medication will be titrated for rotigotine and ropinirole until an individual optimal dose is achieved. Following a Titration period of up to 4 weeks in the rotigotine arm and 6 weeks in the ropinirole arm, subjects will be maintained on the optimal or maximal dose for 4 weeks. At the end of the Maintenance period, subjects will be given the opportunity to enter a 2-year rotigotine patch extension trial. The first subject was enrolled in December 2004. The last subject was enrolled in June 2005. Last subject out is expected for October 2005. The trial is still ongoing.
The purpose of this trial is to assess whether it is possible for subjects with idiopathic Parkinson's Disease to switch from ropinirole, pramipexole and cabergoline to rotigotine transdermal system (SPM 962) overnight without worsening of Parkinson's Disease symptoms. Subjects who meet eligibility criteria will be switched overnight to treatment with rotigotine transdermal patches at a dose considered equivalent to the dose of dopamine agonist that the subject is currently taking. Subjects on ropinirole or pramipexole will take their last dose at bedtime and then apply rotigotine patch(es) upon awakening the next morning. Subjects on cabergoline will apply rotigotine patches 24 hours after the final dose of cabergoline. Subjects will continue rotigotine treatment for 28 days, during which dose can be increased or decreased as needed. At the end of treatment, subjects can select to enroll in an open-label extension trial. The first subject was enrolled on 28 December 2004. The last subject was enrolled in June 2005 and the last subject visit was conducted in July 2005. This study is now closed.
