| NCT00823836 | Clinical Evaluation of Ropinirole Prolonged Release/Extended Release (PR/XR) Tablet for Adjunctive Therapy to L-dopa in Subjects With Advanced Parkinson's Disease | PHASE3 | COMPLETED | 302 | — | — | Mar 1, 2009 | Dec 1, 2010 | Jan 18, 2017 | 54 | Japan |
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. Mean change from Week 0 was calculated as the total score at FAP minus the total score at Week 0. Participants who withdrew before Week 2 and who had only one observation for the part III total score were not included in the analysis.

| ropinirole PR/XR | DRUG | Double-blind non-inferiority verification phase (24 weeks) At the baseline visit (Week 0), subjects who completed screening period will be randomised (1:1) to double-blind treatment with either ropinirole PR-PR group or ropinirole IR-PR group. The subjects'dose will be titrated according to the recommended schedule to achieve an optimal therapeutic response (ropinirolePR/XR2-15 mg/day ,ropinirolIR0.75-15 mg/day). Double-blind PR/XR switching phase (8 weeks) Ropinirole IR-PR subjects will be switched overnight to a similar dose of ropinirole PR/XR, while the remaining ropinirole PR-PR group will continue on the same dosage. Double blind long-term treatment phase (22 weeks) The same dose level at the end of PR/XR switching phase will be continued till week 54 under blind. Down titration phase Subjects who complete Week 54 or withdrawn will be down titrated over a 1 to 4 weeks period. |
