A double-blind, placebo-controlled, crossover, dose-range finding study in patients with Parkinson's disease and levodopa-induced dyskinesia. The study will examine the effects of three different doses of eltoprazine HCl, compared to placebo, on severity of dyskinesia, parkinsonian symptoms, patient function, safety and tolerability, using Parkinson's disease rating scales, patient diaries and physiological measurement of abnormal movement by means of motion sensors.
The purpose of this study is to evaluate the safety, tolerability and efficacy of eltoprazine to treat levodopa-induced dyskinesia in patients with Parkinson's disease
