New hope for PMR patients: drug may reduce need for steroids
NCT ID NCT05533125
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether rituximab, a drug that calms the immune system, can help people with polymyalgia rheumatica (PMR) stop taking steroids sooner. PMR causes pain and stiffness, and steroids are the main treatment but have side effects. The trial included 114 newly diagnosed patients and compared rituximab to a placebo, with the goal of seeing if more patients could achieve remission without steroids after one year.
