International audience; BackgroundExcessive daytime sleepiness (EDS) is a frequent and disabling symptom of Parkinson's disease (PD) without approved treatment.
THN102 is a novel combination drug of modafinil and low-dose flecainide.ObjectiveThe aim of this study is to evaluate the safety and efficacy of THN102 in PD patients with EDS.MethodsThe method involved a randomized, double-blind, placebo-controlled, crossover trial testing two doses of THN102 (200 mg/d modafinil with 2 mg/d [200/2] or 18 mg/d flecainide [200/18]) versus placebo; 75 patients were exposed to treatment.
The primary endpoint was safety.
The primary efficacy outcome was the change in Epworth Sleepiness Scale (ESS) score.ResultsBoth doses of THN102 were well tolerated.
ESS significantly improved with THN102 200/2 (least square means vs. placebo [95% confidence interval, CI]: −1.4 [−2.49; −0.31], P = 0.012) but did not change significantly with the 200/18 dosage.ConclusionsTHN102 was well tolerated and showed a signal of efficacy at the 200/2 dose, supporting further development for the treatment of EDS in PD.
