What this trial studies

This clinical trial investigates the effectiveness of Solriamfetol, a wake-promoting agent, in alleviating fatigue in patients with Multiple Sclerosis (MS). The study employs a randomized, double-blind, placebo-controlled crossover design, where participants will receive either the medication or a placebo over two four-week treatment periods, separated by a washout week. Fatigue levels will be primarily assessed using the Modified Fatigue Impact Scale (MFIS), alongside innovative real-time measurements through a smartphone app. This approach aims to provide a more detailed understanding of fatigue fluctuations in MS patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 60 with a confirmed diagnosis of Multiple Sclerosis who experience significant fatigue.

Not a fit: Patients with a history of coronary artery disease or uncontrolled hypertension may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients suffering from fatigue related to Multiple Sclerosis.

How similar studies have performed: Previous studies have shown limited effectiveness of current treatments for MS-related fatigue, making this approach novel and potentially impactful.
