Descriptive comparisons of the effect of apremilast and methotrexate monotherapy in oligoarticular psoriatic arthritis: The corrona psoriatic arthritis/spondyloarthritis registry results

Objective. Therapeutic response was evaluated among new apremilast, methotrexate (MTX), or biologic disease-modifying antirheumatic drug (bDMARD) initiators with oligoarticular psoriatic arthritis (PsA). Methods. Patients with oligoarticular PsA in the Corrona PsA/Spondyloarthritis Registry initiating treatment with apremilast, MTX, or bDMARD, and completing 6-month follow-up were included. Results. In total, 150 patients initiated monotherapy (apremilast: n = 34; MTX: n = 15; bDMARD: n = 101). Apremilast initiators had higher baseline disease activity than MTX initiators. At follow-up, apremilast initiators experienced numerically greater disease activity improvements than MTX initiators and similar improvements to bDMARD initiators. Conclusion. Findings suggest apremilast monotherapy is an effective option for patients with oligoarticular PsA.
