Exclusion criteria
Exclusion criteria: Atypical parkinsonian syndromes due to drugs (e.g., metoclopramide, flunarizine), metabolic disorders (e.g., Wilson's disease), encephalitis or degenerative diseases (e.g., progressive supranuclear palsy). Dementia, as defined by a Mini-Mental State Exam score 2 ULN (on screening lab test). Patients with a creatinine clearance < 50 mL/min (estimated by the Modification of Diet in Renal Disease - MDRD - formula and calculated by the central lab on screening lab test) Any dopamine agonist (including pramipexole) within 4 weeks prior to baseline visit, or L-Dopa within 8 weeks prior to baseline visit. Total cumulative duration of prior exposure to Levodopa of more than 3 months. Any medication (including intra-muscular formulations) with central dopaminergic antagonist activity within 4 weeks prior to the baseline visit (i.e. typical neuroleptics, atypical antipsychotics, reserpine, methyldopa, centrally-active antiemetics, etc).

| Measure | Time frame |
|---|---|
| Main Objective: To determine the efficacy (as measured by the change from baseline to the end of the maintenance period in the total score for UPDRS parts II and III combined), safety and tolerability of Pramipexole ER compared with placebo and Pramipexole IR in patients with early Parkinson's disease. Superiority of pramipexole ER to placebo and non-inferiority of pramipexole ER to IR will be evaluated in a hierarchical system of hypotheses.;Secondary Objective: Cost-effectiveness analysis Pramipexole plasma concentrations (exposure) will be assessed ;Primary end point(s): The primary efficacy endpoint of the trial is the change from baseline to end of the maintenance period in UPDRS parts II+III score. | — |
