Transcutaneous Vagus Nerve Stimulation in SLE

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease. Joint and muscle pain and fatigue are extremely common among patients and contribute to a reduced quality of life. Available therapies may be associated with significant side effects and many patients do not achieve an adequate response to these treatments. Therefore, there is an unmet need to develop new strategies to reduce pain and fatigue. Filling this need would significantly improve patients' quality of life. This trial will evaluate the effects of a novel approach, stimulating the vagus nerve, a nerve originating in the brain as a potential therapeutic intervention for treatment of musculoskeletal pain and fatigue. Vagus nerve stimulation has multiple beneficial effects and is one of the body's own ways to modulate the immune system. One can stimulate the vagus nerve via the skin at the neck or at specific locations in the ear, (transcutaneous vagus nerve stimulation: tcVNS). We recently completed a short, small scale randomized, placebo controlled trial of tcVNS in patients with SLE and observed dramatic benefits on musculoskeletal pain and fatigue. The treatment was safe without side effects. We are therefore proposing a longer trial to validate our initial findings and to look at durability. In this study, 18 patients with musculoskeletal pain will be followed for 2 months and will receive tcVNS or placebo (sham stimulation) for 5 minutes/day for 28 days. Patients will have a 1 out of 3 chance of receiving sham stimulation and neither the patient nor the evaluating investigator will know the actual treatment. The stimulations are self-administered, are non-painful and have not been associated with serious risks. After 28 days of stimulation, treatment will be discontinued and patients will be monitored for an additional 28 days to evaluate durability. Pain, fatigue and disease activity will be evaluated as well as possible side effects will be monitored throughout the trial. This study will also explore biologic mechanisms that may be responsible for the potential clinical effects. This will include possible effects of stimulation on gut permeability and the stool microbiome, areas that may play a significant role contributing to SLE disease and its manifestations. The development of an effective treatment without significant side effects would be extremely valuable and a significant advance for patients with SLE. If efficacious, tcVNS offers a non-toxic, non-immunosuppressive strategy to control two of the most common symptoms of this disease.
