Safety of Splenic Stimulation for RA

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.

* Have an appropriate washout from previously used biological DMARDs or JAKi
* A female participant should have no child-bearing potential

Exclusion Criteria:

* Inability to provide informed consent.

* Previous splenectomy
* Any investigational small molecule drug or biological within 2 weeks or 2 half-lives whichever is longer, before surgery.
* Uncontrolled other inflammatory diseases
* Current/recurrent infections that in the opinion of the PI risk\>benefit.
