Official title
A Double-blind, Crossover, Placebo-controlled Study to Compare the Effects of Nighttime Administration of Suvorexant in Patients With Multiple Sclerosis Fatigue and Insomnia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study assesses the safety, tolerability, and efficacy of suvorexant in multiple sclerosis patients. Enrolled subjects will receive 2 weeks of treatment during treatment period 1 with either suvorexant or matching placebo (1:1). After treatment period 1, subjects will undergo a washout period of 1 week then 2 weeks of the alternate treatment (either suvorexant or placebo). The primary hypothesis is that suvorexant will provide greater improvement in sleep, as measured by symptom rating scales, compared to placebo.
