NCT ID NCT06170970

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether solriamfetol (Sunosi), a drug used for sleepiness, can reduce fatigue in people with multiple sclerosis who also have excessive daytime sleepiness. About 46 participants will receive either the drug or a placebo for four weeks, then switch after a washout period. The study uses a smartphone app to track fatigue through typing patterns, aiming for more precise measurements.
