Background: This study sought to evaluate the efficacy and safety of tofacitinib in patients with rheumatoid arthritis with distinct treatment histories. Methods: Pooled phase II/III trial data from patients who received tofacitinib 5 or 10 mg twice daily or placebo, as monotherapy or with conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs), were analyzed post hoc. Separate evaluations were conducted for populations with a prior inadequate response (IR) to: 1) non-methotrexate (MTX) csDMARDs only (non-MTX csDMARD-IR; n = 537); 2) MTX (MTX-IR; n = 3113); and 3) biologic (b)DMARDs (bDMARD-IR; n = 782). Efficacy outcomes included rates of response (American College of Rheumatology 20/50/70% response criteria) and remission (Disease Activity Score in 28 joints derived from 4 measures, erythrocyte sedimentation rate [DAS28-4(ESR)] < 2.6) at month 3, and changes from baseline in DAS28-4(ESR) and Health Assessment Questionnaire–Disability Index scores. Safety was assessed up to month 24. Results: At month 3, efficacy was generally improved with tofacitinib (both doses) vs placebo in each population. Generally, efficacy outcomes with tofacitinib were numerically more favorable in non-MTX csDMARD-IR vs MTX-IR or bDMARD-IR patients. Over 24 months, crude incidence rates for adverse events (AEs), serious AEs, and discontinuations due to AEs were generally numerically lower in non-MTX csDMARD-IR and MTX-IR vs bDMARD-IR populations; rates for AEs of special interest were generally similar across populations. Conclusions: Tofacitinib provided clinical benefit across patients with rheumatoid arthritis with a range of prior treatment experience but may have greater efficacy and an improved benefit/risk profile in those with fewer prior treatments.
