Conditions

Motor fluctuations in advanced Parkinson’s disease

Brief summary

The primary endpoint is the change in good ON time at Week 12 compared to baseline for IPX203 versus IR LD/CD (>1 hour; ≤1 hour)

Detailed description

Change from baseline in OFF time at Week 12 (key secondary), Change from baseline in ON time, change from baseline in ON time with dyskinesia, change from baseline in ON time with troublesome dyskinesia, change from baseline in ON time with non-troublesome dyskinesia, and change from baseline in ON time without dyskinesia (all derived from the Parkinson’s disease [PD] diary), Change from baseline scores for the clinical outcome assessments listed in the protocol.
