A review of tofacitinib efficacy in rheumatoid arthritis patients who have had an inadequate response or intolerance to methotrexate
Introduction: Tofacitinib is a pan JAK inhibitor with specificity for JAK3 over JAK1 over JAK2, which is approved in many countries for the treatment of rheumatoid arthritis (RA), including the United States and the European Union, either as monotherapy or in combination with conventional synthetic disease modifying anti-arthritis drugs (csDMARDs). Phase 2, 3 and 4 clinical trials have investigated the efficacy and safety of tofacitinib given either as monotherapy or in combination with csDMARDs.
Areas covered: This review reports the safety, clinical, functional, and radiographic efficacy, of tofacitinib used as monotherapy in the treatment of adult patients with RA reported in the prospective, double-blind, controlled randomized trials reported to date. One critical clinical question is whether tofacitinib monotherapy has similar efficacy as tofacitinib in combination with methotrexate (MTX); this question has recently been addressed. A literature search on tofacitinib monotherapy was carried out using the PubMed database up to July 2017.
Expert opinion: Although tofacitinib plus MTX is statistically more clinically effective, tofacitinib monotherapy is effective in many patients with RA.
