Abstract
Introduction: A key factor of biologic discontinuation in plaque psoriasis patients is loss of response over time; long-term treatment efficacy is therefore important.1 Here, 3-year efficacy of bimekizumab (BKZ) from a pooled analysis of patients with moderate to severe plaque psoriasis across 3 phase 3 clinical trials and their open-label extension (OLE) is reported.
Procedure/study: Data were pooled from the 52-week BE VIVID and 56-week BE SURE and BE READY phase 3 trials, and their common OLE BE BRIGHT.2–5 Included patients received BKZ 320 mg every 4 weeks (Q4W) then switched to Q4W or Q8W maintenance dosing from Week 16 onwards, and entered the OLE; from OLE Week 48 or the next scheduled visit, all patients received BKZ 320 mg Q8W. Proportions of patients achieving ≥90% improvement from baseline in Psoriasis Area and Severity Index (PASI 90), PASI 100, and Dermatology Life Quality Index (DLQI) 0/1 are reported through Year 3 using modified non-responder imputation: patients who discontinued treatment due to lack of efficacy or treatment-related adverse events were considered non-responders at subsequent timepoints; multiple imputation was used for all other missing data.
Results: 771 patients received BKZ continuously in the feeder studies and entered the OLE. Among these, at Week 16, 90.9%, 65.8%, and 71.5% achieved PASI 90, PASI 100, and DLQI 0/1, respectively. At Year 1, 93.7%, 76.6%, and 83.1% of all BKZ-treated patients achieved PASI 90 (Week 52), PASI 100 (Week 52), and DLQI 0/1 (Week 48/52), respectively. Responses were durable to Year 3 (OLE Week 96): 91.0%, 70.3%, and 82.8% of all BKZ-treated patients achieved PASI 90, PASI 100, and DLQI 0/1, respectively. Similar trends were observed in the subset of patients that received BKZ Q4W/Q8W/Q8W (initial/maintenance/OLE).
Conclusion: High and durable clinical and health-related quality of life responses were observed over 3 years of BKZ treatment across 3 phase 3 trials and their OLE.
