Phase I Study of Circadian Focused Light Therapy in Progressive Multiple Sclerosis
The study is being done to determine if treatment with a novel form of light therapy is tolerated in patients with progressive multiple sclerosis. The goal of this trial to establish the safety profile of this light therapy while generating data on its impact on fatigue, as well as its mechanism of action. Fatigue is often a complex symptom in multiple sclerosis, without any FDA-approved direct therapy. Fatigue is traditionally treated with symptom management through a multidisciplinary team.
