We assessed the relative efficacy and safety of once-daily administration of 15 and 30 mg upadacitinib (a JAK1-selective inhibitor) in patients with active rheumatoid arthritis (RA). ⋯ Upadacitinib 15 and 30 mg administration once daily in combination with MTX was the most efficacious intervention for active RA, with no significant risk for SAEs.
