Brief summary

The general aim of this study is to obtain long-term safety and tolerability data on pramipexole ER, in daily doses from 0.375mg to 4.5mg once daily (q.d), in patients who have previously completed a pramipexole double-blind study in early PD (248.524(NCT00479401) or 248.636(NCT00558025) trial).

Interventions

DRUGPlacebo

Patient to receive placebo tablets identical to Pramipexole ER tablets. Only during transfer phase.
