Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* outpatient with idiopathic PD
* stable dose of anti-parkinsonian medication for at least four weeks before the Screening Visit
* daily levodopa dose ≥300 mg per day divided into at least three doses
* treated with levodopa for at least three years prior to study entry
* moderate to severely disabling levodopa-induced dyskinesia for at least three months prior to study entry
* dyskinesia for, on average, \>25% of the waking day

Exclusion Criteria

* inability to use the motion sensors or electronic diaries correctly
* surgical treatment for PD, e.g. Deep Brain Stimulation, within the last six months or planned during the study
* unstable co-existing psychiatric disease including psychosis, depression or cognitive impairment
* Mini Mental State Examination score of \<24
* moderate or severe renal, or severe hepatic, impairment
