Vagus Nerve Stimulation for Moderate to Severe Rheumatoid Arthritis

The RESET-RA study is an operationally seamless, 2-stage, randomized, double-blind, sham-controlled, multicenter pivotal study enrolling up to 250 subjects at up to 45 study centers across the U.S. The study will assess the safety and efficacy of the SetPoint System (study device) for the treatment of adult patients with active, moderate to severe rheumatoid arthritis (RA) who have had an inadequate response, loss of response or intolerance to biologic or targeted synthetic Disease-Modifying Anti-Rheumatic Drugs (DMARDs). 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. Half of the subjects will receive active stimulation (the treatment group) and the other half will receive non-active stimulation (the control group). Stimulation will be delivered for 1 min once per day for 12 weeks. After completing primary endpoint assessments at Week 12, there will be a one-way crossover of control subjects to active stimulation and a 252-week open-label follow-up with all subjects (treatment and control) receiving active stimulation to evaluate long-term safety. Blinding will be maintained until the last enrolled and randomized subject in Stage 2 completes Week 12 assessments, and the study database is locked.
