A randomized, double‐blind, placebo‐controlled trial of camicinal in Parkinson's disease
- Abstract:
-
Background: Delayed gastric emptying may impair ʟ-dopa absorption, contributing to motor fluctuations. We evaluated the effect of camicinal (GSK962040), a gastroprokinetic, on the absorption of ʟ-dopa and symptoms of PD.
Methods: Phase II, double‐blind, placebo‐controlled trial. Participants were randomized to receive camicinal 50 mg once‐daily (n = 38) or placebo (n = 20) for 7 to 9 days.
Results: ʟ-dopa exposure was similar with coadministration of camicinal compared to placebo. Median time to maximum ʟ-dopa concentration was reduced, indicating more rapid absorption of ʟ-dopa. Camicinal resulted in significant reduction in OFF time (–2.31 hours; 95% confidence interval: –3.71, –0.90), significant increase in ON time (+1.88 hours; 95% confidence interval: 0.28, 3.48) per day, and significant decrease in mean total MDS‐UPDRS score (–12.5; 95% confidence interval: –19.67, ‐5.29). Camicinal treatment was generally well tolerated.
Conclusions: PD symptom improvement with camicinal occurred in parallel with more rapid absorption of ʟ-dopa. This study provides evidence of an improvement of the motor response to ʟ-dopa in people with PD treated with camicinal 50 mg once‐daily compared with placebo, which will require further evaluation.
