Bimekizumab Impact on Patient-Reported Outcomes in Plaque Psoriasis: 4-Year Results from BE SURE, BE VIVID, BE READY, and BE BRIGHT

Introduction: While bimekizumab has demonstrated rapid, superior clinical efficacy versus adalimumab and ustekinumab, with sustained responses through 4 years, its comparative and long-term impact on patient-reported outcomes (PROs) remains underexplored. Here, we report PROs with bimekizumab versus adalimumab/ustekinumab/placebo in phase 3 controlled trials, and over 4 years with bimekizumab. Methods: Data were analyzed from BE SURE, BE VIVID, BE READY (52/56 weeks), and their open-label extension (OLE), BE BRIGHT (144 weeks; 4 years’ total treatment). Patients were randomized to bimekizumab/adalimumab/ustekinumab/placebo during comparator-controlled periods; all received bimekizumab during BE BRIGHT. Proportions of patients reporting Psoriasis Symptoms and Impacts Measure (P‑SIM) = 0 and Dermatology Life Quality Index (DLQI) = 0 (both at item-level) were assessed during comparator‑controlled periods using non-responder imputation (NRI). Over 4 years, PROs were analyzed using modified NRI in patients who received continuous bimekizumab from baseline into the OLE. Results: BE SURE included 478 patients (bimekizumab, 319; adalimumab, 159); BE VIVID included 567 (bimekizumab, 321; ustekinumab, 163; placebo, 83); BE READY included 435 (bimekizumab, 349; placebo, 86). In total, 771 patients received continuous bimekizumab into the OLE. A larger proportion of bimekizumab-treated patients achieved P-SIM = 0 across key items versus adalimumab (week 24; itching, 30.7% vs. 18.9%; skin pain, 43.9% vs. 30.2%; scaling, 39.2% vs. 19.5%), ustekinumab (week 16; itching, 31.2% vs. 17.8%; skin pain, 51.7% vs. 27.6%; scaling, 43.6% vs. 17.2%), and placebo. Similar trends were seen for other P-SIM items and in proportions of bimekizumab-treated patients reporting DLQI = 0 across items versus comparators. The patient-reported benefits of bimekizumab were demonstrated throughout the OLE, with 65.5–94.8% of patients reporting DLQI = 0 across items at 4 years. Conclusions: Bimekizumab provided greater improvements in PROs versus comparators, with durable effects over 4 years. These findings reinforce bimekizumab’s role in effective psoriasis management, linking clinical efficacy with sustained patient-reported benefits.
