Study of the Effect of SR57667B on 18F-Dopa PET Imaging in Patients With Parkinson's Disease
A Phase II, Randomized, Multicenter, Multinational, Double-Blind, Placebo-Controlled, Study of the Effect of SR57667B on Dopaminergic Nigro-Striatal Function Assessed by 18F-Dopa PET Imaging in Outpatients With Early Parkinson's Disease

Brief Summary
- The primary objective is to study the effect of SR57667B at the dose of 4 mg/d on progression of dopaminergic nigro-striatal lesions assessed by 18F-Dopa PET imaging.
- Secondary objectives are to assess the effect of SR57667B on symptomatic decline in patients with early PD, to assess the safety/tolerability of SR57667B in patients with early PD and to document plasma concentrations of SR57667 in patients with early PD.

Eligibility Criteria
You may qualify if:
- Male or female outpatients.
- Age \>=35 years at screening.
- Diagnosis of Parkinson's syndrome, on at least two of the three key Parkinson's symptoms, i.e. resting tremor, bradykinesia and rigidity.
- Duration of the disease of less than 3 years since diagnosis.
- Modified Hoehn and Yahr stage \<= 2.5.
- Patient optimized on monotherapy by levodopa or a dopamine agonist·
- Generally healthy and ambulatory.
- Patient has given his informed written consent and is capable of following study procedures.
You may not qualify if:
- Any indication of forms of parkinsonism other than PD.
- Severe resting tremor. Presence of either dyskinesia, fluctuations, or loss of postural reflexes·
- Treatment with amantadine, anticholinergics, catechol-o-methyltransferase (COMT ) inhibitors, selegiline, dopamine receptor antagonists, catecholamine depleters, indirect dopamine agonists or alphamethyldopa. Electroconvulsive therapy (ECT).Use of CYP3A4 strong, and moderate inducers or inhibitors. Participation in another clinical trial with an investigational drug within two months prior to randomization.
- Dementia, uncontrolled depression, psychotic disorder. History of substance-related disorders including alcohol or other substance use disorders.
- Females of child bearing potential.
- Evidence (detected by history, physical examination and/or laboratory/ECG tests) of any clinically significant or unstable medical disorder that could interfere with the patient's participation in the clinical trial; interfere with the absorption, metabolism or excretion of the study medication; or interfere with the evaluation of the study drug. Alterations of laboratory tests or ECG findings of potential clinical significance.
