The primary objective is to assess the effect of SR57667B at the dose of 4 mg/d on the progression of Parkinson symptoms in patients with early PD. The primary outcome will be the time to progression of disability warranting initiation of L-dopa or a dopamine agonist. Secondary outcomes will comprise assessments of symptoms, activities of daily living and global clinical status.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 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.
  • Untreated patients.
  • Generally healthy and ambulatory.
  • Patient has given his informed written consent and is capable of following study procedures.

Exclusion Criteria:

  • Any indication of forms of parkinsonism other than PD.
  • Severe resting tremor.
  • Presence of either dyskinesia, fluctuations, or loss of postural reflexes·
  • Treatment with L-Dopa, dopamine agonist, 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.
