Abstract

Abstract : Background: Tofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis (RA). Objectives: To assess the safety of tofacitinib in patients from Latin America (LA) and the rest of the world (ROW). Methods: Data were pooled from patients who received tofacitinib 5 or 10 mg twice daily ± conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) from two Phase 1, nine Phase 2, six Phase 3 and two long-term extension (LTE) studies (one LTE was ongoing at time of analysis, data as of March 2015). Incidence rates (IR; patients with events/100 patient-years) and 95% confidence intervals (CI) for safety events of special interest pooled for both tofacitinib doses were calculated and compared between LA and ROW patient populations. LA countries that enrolled patients were: Argentina, Brazil, Chile, Colombia, Costa Rica, the Dominican Republic, Mexico, Peru and Venezuela. Results: The analysis included 1037 LA patients (91.2% female; mean age 49.5 years; 7.5 years mean RA duration; 67.1 kg mean weight; 6.5 mean baseline Disease Activity Score for 28-joint counts based on erythrocyte sedimentation rate [DAS28-4(ESR)]; 71.3% baseline concomitant steroid use) and 5157 ROW patients (81.0% female; mean age 53.7 years; 8.1 years mean RA duration; 71.9 kg mean weight; 6.3 mean baseline DAS28-4 [ESR]; 63.8% baseline concomitant steroid use). IRs for safety events of special interest were generally similar for LA and ROW populations with overlapping 95% CIs (Table ). Conclusions: In this analysis of pooled data from tofacitinib RA trials, the safety profile of tofacitinib in the LA and ROW populations was similar.
