Primary Outcome Measures

Name	Time	Method
Main Objective: To investigate the efficacy of pramipexole, compared with placebo in treating Parkinson’s disease patients with stable motor function and depressive symptoms. The efficacy of pramipexole vs. placebo will be based on the Beck Depression Inventory (BDI) total score. ;Secondary Objective: To assess further depression response (% patients with 50% reduction from baseline in total BDI score, GDS total score, and UPDRS part I), motor function (standard version UPDRS part II & III), complications of therapy (UPDRS part IV), anhedonia (SHAPS), quality of life (PDQ-39 and EQ-5D), Clinical Global Improvement (CGI-I) and pain (VAS);Primary end point(s): The primary endpoint for this study is clinical response after 12 weeks of treatment, defined as a change in total score of baseline symptoms as measured by the BDI total score.
