The SetPoint System as a Pro-Remyelination Therapy for Relapsing-Remitting Multiple Sclerosis: A Pilot Study
What this study is about
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 the usual treatment therapy for RRMS.
View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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).
- Best corrected high-contrast (HCVA) better than 20/200 Snellen equivalent or letter score of 35
- Best corrected low-contrast letter acuity (LCLA) by Sloan chart (2.5% black on white) of no better than 40 letters in the VEP-qualifying eye (Snellen equivalent of 20/40). (Best corrected LCLA must be worse than best corrected HCVA.)
- Absence of clinical relapse for at least 12 months prior to informed consent
- No new lesions or increase in existing lesion volume on most recent clinic brain MRI (must be within 1 year of consent)
- Taking a stable regimen of disease-modifying therapy (DMT) prior to informed consent. If intermediate-potency DMT, the DMT must have been started and maintained for at least two years prior to consent. If high-potency DMT, the DMT must have been started and maintained at least one year prior to consent.
- Score of 2.5 to 6.0 by Expanded Disability Status Scale (EDSS) at baseline, with at least of 2 on the functional systems pyramidal function.
Exclusion criteria
- 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.
- Documented optic neuritis in the qualifying eye greater than 5 years before screening.
- Steroid treatment for MS symptoms in the 30 days prior to consent
- Hypersensitivity/allergy to MRI contrast agents and/or unable to perform MRI (e.g., claustrophobia).
- Regular use of or dependency on nicotine products within the past year.
- Not a surgical candidate.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
