Safety of upadacitinib in Latin American patients with rheumatoid arthritis: an integrated safety analysis of the SELECT phase 3 clinical program.

Introduction/objectives: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by ongoing inflammation and degradation of synovial joints. The oral JAK inhibitor, upadacitinib, is approved for RA. We conducted an integrated safety analysis of upadacitinib 15 mg once daily (QD) in patients from Latin America (LATAM) versus the rest of the world (RoW).
