PG - 1249-1258 LID - 10.1007/s10067-023-06513-y [doi] AB - 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). METHODS: Treatment-emergent adverse events (AEs) and laboratory data from six phase 3, randomized controlled trials, adjusted for upadacitinib 15 mg QD use in RA, were analyzed. RESULTS: Overall, 3209 patients received upadacitinib 15 mg QD for 7024 patient-years (PY). LATAM patients (n = 725) had a mean upadacitinib exposure of 1518 PY. Baseline characteristics were generally similar between LATAM and RoW populations. AE rates (including serious/opportunistic infections, tuberculosis, and herpes zoster) and deaths were comparable between populations. LATAM patients had lower serious AE rates per 100 PY (9.4 vs 14.0 E/100 PY) and discontinuation-related AEs (3.9 vs 6.0 E/100 PY) versus RoW. Rates of cardiovascular events were low (
