Brief summary

This study will evaluate the safety and tolerability of stimulating the splenic neurovascular bundle (NVB) with the Galvani System, which consists of a lead, implantable pulse generator, external components and accessories. Participants eligible for implant will have active rheumatoid arthritis (RA) and have an inadequate response or intolerance to at least two biologic Disease Modifying Anti-Rheumatic Drugs (DMARDs) or JAK inhibitors (JAKis). Five participants will be implanted with the device and receive neurostimulation for 12 weeks.

Detailed description

The study will be an open-label single-arm study to evaluate the safety and tolerability of Galvani's neuromodulation system. Participants with active rheumatoid arthritis (RA) will be implanted with the Galvani system and receive active stimulation for 12 weeks. The total study duration in the study for each participant is approximately 5 months, with a 4-week screening period, 4 weeks recovery from surgery and a 12-week 'treatment' period. The participants will return to the clinic on pre-defined days for follow-up visits during the trial period. At Days 42 and/or Day 56, if study participants are not responding to stimulation, stimulation parameters might be adapted. At the end of the study (Day-84), participants will enroll in a long-term follow-up study up to 5-years after enrollment in this study.

Interventions

The Galvani System will be implanted in eligible participants, and stimulation will be turned ON
