Could a cheap arthritis drug replace steroids for transplant complications?

This study tested leflunomide, a drug used for rheumatoid arthritis, as a first-line treatment for musculoskeletal graft-versus-host disease (GVHD), a complication of bone marrow transplants where donor cells attack the patient's muscles and joints. The goal was to see if leflunomide could be a safer alternative to steroids, which often cause severe side effects. Only 1 person enrolled before the study was terminated, so no firm conclusions can be drawn.
