Mean Change From Baseline in the Japanese Unified Parkinson's Disease Rating Scale (UPDRS) Part III Total Score (in "On" State for the ROP+L-Dopa Group) at Week 52 and Final Assessment Point (FAP) [ Time Frame: Baseline, Week 52, and FAP (up to Week 52) ]
The Japanese UPDRS assesses the status of Parkinson's Disease (PD) patients objectively. Part III assesses motor examination on 27 items. Participants receive a score of 0-4 points per item. The maximum total score is 108 points. A higher score indicates more severe PD symptoms. "On" state is where PD symptoms are well controlled by the drug. Participants with "off" state at baseline or without post-baseline data were not included in the ROP+L-dopa group at FAP. These participants as well as one with "off" state at Week 52 and those prematurely withdrawn were not included at Week 52.
Efficacy <Adjunct Therapy Group (REQUIP+L-dopa)> - Change from baseline in Japanese UPDRS Part III total score (recorded in an "on" state) <Monotherapy Group (REQUIP alone)> - Change from baseline in Japanese UPDRS Part III total score

REQUIP (Ropinirole Hydrochloride) IR Long-Term Phase 4 Study
Post-Marketing Clinical Study of REQUIP (Ropinirole Hydrochloride) Tablets in Patients With Parkinson's Disease- Evaluation of Long-Term Efficacy and Safety -

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.

In the 4-week Fixed Titration Phase (from Week 0 as Baseline), the dose will start at 0.75 milligrams (mg)/day and will be increased weekly by 0.75 mg/day up to 3.0 mg/day. In the 48-week Flexible Titration and Maintenance Phase, the dose will be increased by 1.5 mg/day at intervals of at least 1 week up to a maximum of 15.0 mg/day.
