Early Adalimumab Induction for Immune Checkpoint Inhibitor Associated Inflammatory Arthritis

Participants will be randomized 1:1 (non-blinded) to receive either adalimumab (40 mg subcutaneous every 2 weeks for 12 weeks) and prednisone vs prednisone alone. Addition of methotrexate (MTX) and/or hydroxychloroquine (HCQ) is permitted, as needed, at the discretion of the treating rheumatologist. No additional conventional synthetic, targeted synthetic or biologic DMARDs are permitted during the trial.

Prednisone as per standard of care.
