Key clinical point: Bimekizumab demonstrated consistent safety and sustained efficacy for up to 2 years in patients with psoriatic arthritis (PsA) who were biologic-naive or inadequately responsive to tumor necrosis factor inhibitors (TNFi-IR).
Major finding: From weeks 52 to 104, the incidence of treatment emergent adverse events (TEAE) was consistent with previous studies, with no new safety signals. SARS-CoV2 infection (18.6 per 100 patient-years) was the most common TEAE. Approximately 50% biologic-naive and TNFi-IR patients maintained a ≥50% improvement in the American College of Rheumatology response.
Study details: This open-label extension ( BE-VITAL) of two phase 3 trials included biologic-naive (n = 852) and TNFi-IR (n = 400) patients with PsA who were randomly assigned to receive bimekizumab, placebo with crossover to bimekizumab at week 16, or adalimumab followed by bimekizumab at week 52.
