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.

Condition or disease Intervention/treatment Phase
Rheumatoid Arthritis Device: Active Stimulation Not Applicable

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.

Arm Intervention/treatment
Experimental: Active Stimulation
Active stimulation for 12 weeks
Device: Active Stimulation
The Galvani System will be implanted in eligible participants, and stimulation will be turned ON

Primary Outcome Measures :
  1. Safety and tolerability of the Galvani system [ Time Frame: 12 weeks ]
    Incidence and relatedness of Adverse Events (AEs), which include clinically significant findings from Laboratory Safety Assessments (clinical chemistry and hematology), vital signs (blood pressure, heart rate, respiratory rate, and body temperature), and 12-Lead ECG

Secondary Outcome Measures :
  1. Effect of stimulation on the change in pharmacodynamic and response biomarkers [ Time Frame: Day 1 to week 12 ]
    Changes from baseline (Day 1) in the levels of LPS-inducible cytokine/ chemokine release, in whole blood assay at different timepoints after start of stimulation

  2. To evaluate the usability of the external Galvani System devices and accessories [ Time Frame: 12 weeks ]
    Summarize feedback collected on questionnaires pertaining to the use of the external Galvani System devices

  3. To evaluate the participants' perception of therapy and sensation [ Time Frame: 12 weeks ]
    Summarize feedback collected on questionnaires

  4. Evaluate device performance [ Time Frame: 12 weeks ]
    Tabulation of device deficiencies
