Key clinical point: Compared with placebo, tofacitinib demonstrated greater improvement in enthesitis in patients with psoriatic arthritis (PsA), irrespective of enthesitis location and severity.
Major finding: Tofacitinib vs placebo led to greater changes in the Leeds Enthesitis Index (LEI) and Spondyloarthritis Research Consortium of Canada Enthesitis Index scores up to month 3, irrespective of baseline enthesitis locations and severities, with all improvements with tofacitinib being maintained and continued through month 6. Among patients with baseline LEI >0 whose enthesitis had resolved at month 1, relapse at month 3 was experienced by 26.3% and 15.6% vs 30.8% of patients treated with 5 mg tofacitinib and 10 mg tofacitinib vs placebo, respectively.
Study details: This post hoc analysis of pooled data from 2 phase 3 studies (OPAL Broaden and OPAL Beyond) and included 710 patients with PsA who received tofacitinib for 6 months or placebo for 3 months.
