IEI patient with arthritis with joint swelling

Interventions

Protocol treatment will begin with Phase I, with activity assessed every 12 weeks, and if the goal (>=50% reduction in CDAI from baseline assessment) is not achieved, the patient will be moved to the
after 36 weeks, patients will continue on the DMARDs they were receiving at the primary endpoint, until a final evaluation at 52 weeks. The primary endpoint will be CDAI at 36 weeks after initiation
