Key clinical point: Bimekizumab demonstrated sustained efficacy and was well tolerated for 52 weeks, regardless of concomitant methotrexate use, in patients with psoriatic arthritis (PsA) who were biologic-naive or intolerant to tumor necrosis factor inhibitors (TNFi-IR).
Major finding: Through week 52, nearly half of the patients receiving bimekizumab with or without methotrexate achieved a ≥ 50% improvement in American College of Rheumatology response (biologic-naive ~55%; TNFi-IR ~48-56%) and minimal disease activity (biologic-naive ~55%; TNFi-IR ~47%). The rates of experiencing at least one treatment emergent adverse event were similar across the subgroups .
Study details: This post hoc analysis of phase 3 trials ( BE OPTIMAL , BE COMPLETE , and BE VITAL ) included biologic-naive (n = 852) or TNFi-IR (n = 400) patients with PsA who received bimekizumab, placebo with crossover to bimekizumab at week 16, or adalimumab, with or without methotrexate.
