Design outcomes

Primary

MeasureTime frame
Main Objective: To determine levodopa plasma level after repeated doses of V1512 in fluctuating PD patients, compared to standard levodopa/carbidopa Sinemet over the course of the day.;Secondary Objective: To correlate plasma levels of levodopa with ON time. To further characterize the safety profile for each treatment.;Primary end point(s): Pharmacokinetic PK evaluation will take place with regard to the following parameters for L-dopa and carbidopa, for each dose administration Cmax; Tmax; AUC0-t. The following pharmacodynamic parameters will be recorded or derived Motor category based on information recorded in the diary cards; troublesome dyskinesia as recorded in the diary cards; UPDRS section III motor component; Preference test
