Summary

To investigate the efficacy and the safety of ropinirole PR/XR tablets to ropinirole immediate release (IR) tablets with advanced Parkinson's disease in conjunction with L-dopa in a double-blind, parallel group comparison study.

Conditions

  • Parkinson Disease

Interventions

DRUG

ropinirole PR/XR

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 Down titration phase Subjects who complete Week 54 or withdrawn will be down titrated over a 1 to 4 weeks period.
