Summary

Ropinirole Hydrochloride (ROP) was granted approval for the treatment of Parkinson's Disease (PD) on 20 October 2006.

ROP is expected to be used for a long term in clinical practice. However, no long-term clinical data with ROP administered three times daily are currently available from Japanese patients, and the clinical experience with ROP at \>10mg/day is limited.

For this reason, this study was designed as a multicenter open-label uncontrolled study.

This study will evaluate the long-term efficacy (Japanese Unified Parkinson's Disease Rating Scale (UPDRS), Awake time spent "Off"/"On", Modified Hoehn \& Yahr stage, Schwab-England scale, Proportion of subjects remaining in this study and Clinical Global Impression (CGI)) and the long-term safety of ROP administered three times daily for in PD patients.
