Design outcomes

Primary

MeasureTime frame
Main Objective: The main objective of this trial is to assess the effect of 3 different doses (20, 40 and 60 mg) of a sublingual new formulation of piribedil in combination with L-dopa on end-of-dose fluctuations in advanced Parkinson's disease patients after a 14-day treatment period. The main objective is to assess the effect of the 40 mg dose versus placebo. The two other comparisons will allow to demonstrate a discrimination between the different doses and to situate the 40 mg towards the 20 mg dose.;Secondary Objective: To assess the local (sublingual) and general acceptability of the different doses of S 90049 (one sublingual administration t.i.d. for 14 days).;Primary end point(s): Primary parameters will be: -time to turn “ON”, -duration of the “ON” phase.
