What this trial studies

This study evaluates the safety and effects of stimulating the splenic neurovascular bundle using the Galvani System in patients with active rheumatoid arthritis (RA) who have not responded adequately to at least two biologic DMARDs or JAK inhibitors. Participants will be randomly assigned to receive either active or sham stimulation for 12 weeks, followed by an open-label phase where non-responders will switch to a market-approved RA drug. Those who respond will enter a treat-to-target phase combining stimulation with medication for up to 24 weeks, followed by a long-term follow-up period of five years to assess safety. The study aims to gather data on the efficacy of this novel approach in managing RA symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 22-75 with active rheumatoid arthritis and inadequate response to at least two biologic DMARDs or JAK inhibitors.

Not a fit: Patients with significant psychiatric disorders, active infections, or those currently using electrically active medical devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new treatment option for patients with rheumatoid arthritis who have not responded to existing therapies.

How similar studies have performed: While the approach of splenic stimulation is novel, similar studies involving electrical stimulation for inflammatory conditions have shown promising results.
