About this trial

The MS pilot study will assess the safety and investigate the remyelinating effects of the SetPoint System (study device) in adult patients with 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 placed under general anesthesia on the vagus nerve through a small incision on the left side of the neck (implant procedure). The study will enroll up to 60 participants at up to 10 sites. All eligible participants will undergo the implant procedure. Two-thirds of the participants will receive active stimulation (treatment) and the one-third will receive non-active stimulation (control). 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.

Eligibility criteria

Qualifiers

Age 22-50 years at informed consent.

Diagnosis of RRMS by revised 2017 McDonald criteria.

Latency delay >118 milliseconds on baseline full-field transient pattern reversal visual evoked potential (VEP) in at least one eye. Both eyes can be included if they meet all inclusion criteria.

Peri-papillary retinal nerve fiber layer (pRNFL) > 70 microns on Optical Coherence Topography (OCT) in the VEP-qualifying eye (sufficient axons).

Disqualifiers

Confounding ophthalmologic disease or impairments/conditions that could interfere with visual testing (e.g., cataracts, disc hemorrhage, macular star, cotton wool spots, macular degeneration, glaucoma, diabetic and/or hypertensive retinopathy, history of detached retina, etc.)

Severe myopia defined as a refractive error of -6.00 diopters or more

Concurrent neurological disorders, including known moderate or severe cervical myelopathy.

Clinical optic neuritis within 6 months before screening.
