Key clinical point: Risankizumab showed consistent long-term efficacy in patients with active psoriatic arthritis (PsA) regardless of baseline demographic, disease characteristics, and prior medication use.
Major finding: At week 24, a higher number of patients receiving risankizumab vs placebo achieved ≥ 20% improvement in the American College of Rheumatology response (ACR20; 46.3%-60.1% vs 15.5%-36.2%) despite varying demographic and disease characteristics. At week 52, similar proportions of patients who were randomized to risankizumab (48.6%-75.8%) or who switched from placebo to risankizumab (43.7%-63.9%) achieved ACR20.
Study details: This post hoc integrated analysis of the phase 3 KEEPsAKE 1 and KEEPsAKE 2 trials included 1235 patients with active PsA and prior inadequate response or intolerance to conventional synthetic or biologic disease-modifying antirheumatic drugs who received risankizumab or placebo with crossover to risankizumab at week 24.
