Abstract

AbstractIntroduction/objectivesRheumatoid 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).MethodsTreatment-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.ResultsOverall, 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 (≤ 0.5 E/100 PY) and similar between populations. Malignancies, excluding non-melanoma skin cancer, were less common in the LATAM population versus RoW (0.2 vs 1.0 E/100 PY). Laboratory abnormalities were similar between populations, with decreases in hemoglobin, lymphocyte, and neutrophil counts, and elevations in liver enzymes and creatine phosphokinase. Mean change from baseline in low- and high-density lipoprotein cholesterol was generally comparable between LATAM and RoW populations.ConclusionUpadacitinib 15 mg QD demonstrated a consistent safety profile across LATAM and RoW patient populations, with no new safety risks observed.Trial registration numbersSELECT-EARLY, NCT02706873; SELECT-NEXT, NCT02675426; SELECT-COMPARE, NCT02629159; SELECT-MONOTHERAPY, NCT02706951; SELECT-BEYOND, NCT02706847; SELECT-CHOICE, NCT03086343.Key Points• This study assessed the safety of upadacitinib 15 mg in patients with rheumatoid arthritis from Latin America compared with patients from the rest of the world participating in the SELECT phase 3 program.• Safety was generally similar between the two groups, including serious and opportunistic infections, tuberculosis, herpes zoster, and cardiovascular events. Malignancy, major adverse cardiovascular events, and venous thromboembolic events were infrequent in the Latin American patients.• Consistent with the known safety profile of upadacitinib, serious infections, herpes zoster, and laboratory abnormalities were the most common safety events in the Latin American population.
