Key clinical point: A dose of 160 mg bimekizumab every 4 weeks demonstrated greater long-term efficacy than 45 or 90 mg ustekinumab every 12 weeks in patients with psoriatic arthritis (PsA) who were biologic-naïve or showed inadequate response to tumor necrosis factor inhibitors (TNFi-IR).
Major finding: At week 52, both biologic-naive (adjusted odds ratio [aOR] 3.33; P < .001) and TNFi-IR (aOR 9.85; P < .001) patients receiving bimekizumab vs 45 mg ustekinumab were more likely to achieve ≥70% improvement in the American College of Rheumatology response, with similar effect observed for bimekizumab vs 90 mg ustekinumab.
Study details: This was matching-adjusted indirect comparison of data from several phase 3 trials of bimekizumab (BE OPTIMAL, BE COMPLETE, and BE VITAL) and ustekinumab (PSUMMIT1 and PSUMMIT2). The trials involved patients with PsA who received bimekizumab (n = 698) or ustekinumab (45 mg: n = 265; 90 mg: n = 262).
