The SetPoint System as a Pro-Remyelination Therapy for Relapsing-Remitting Multiple Sclerosis: A Pilot Study

The MS pilot study is a 2:1 randomized, double-blind, sham-controlled, multi-center pivotal study enrolling up to 60 subjects at up to 10 study centers across the U.S. The study will assess the safety and investigate the remyelinating effects of the SetPoint System (study device) in adult patients diagnosed with relapsing-remitting multiple sclerosis (RRMS). The SetPoint System is intended for adjunctive use with standard of care therapy for RRMS. The study device contains a miniaturized stimulator (implant) that is surgically implanted inside the left side of the neck on the vagus nerve (implant procedure). The implant delivers a small amount of electricity (stimulation) to the nerve. All eligible subjects will undergo the surgery under general anesthesia. Two-thirds of the subjects will receive active stimulation (the treatment group) and the other one-third will receive non-active stimulation (the control group). Stimulation will be delivered for 1 min once per day for 48 weeks. Following treatment evaluations at Week 48, there will be a one-way crossover of control subjects to active stimulation and a 48-week open-label follow-up with all subjects (treatment and control) receiving active stimulation to evaluate long-term safety. Blinding will be maintained for each individual participant until that participant has completed their Week 48 assessments.
