Bimekizumab efficacy and safety in patients with moderate to severe plaque psoriasis: two-year interim results from the open-label extension of the randomized BE RADIANT phase 3b trial

Abstract: Background
Bimekizumab is a monoclonal IgG1 antibody that inhibits interleukin-17A/F. Bimekizumab is more efficacious than secukinumab over 1 year in the treatment of psoriasis.

Objective
Evaluate the safety and efficacy of bimekizumab through 2 years in patients with moderate to severe plaque psoriasis.

Methods
The BE RADIANT phase 3b randomized controlled trial consisted of a 48-week double-blinded period, where patients received bimekizumab (320 mg every 4 or 8 weeks) or secukinumab (300 mg weekly to Week 4, then every 4 weeks), and an open-label extension (OLE). From Week 48, all patients received bimekizumab in the OLE.

Results
At Week 48, more patients achieved complete skin clearance (PASI 100; modified non-responder imputation) with bimekizumab than secukinumab (74.8% vs 52.8%). PASI 100 responses were maintained to Week 96 in continuous bimekizumab patients (70.8%); patients who switched from secukinumab to bimekizumab had increased rates at Week 96 (76.6%). The most common adverse events were: nasopharyngitis, oral candidiasis, and urinary tract infection. Safety data were consistent with the known safety profile of bimekizumab.

Limitations
Limited racial diversity; overlap with the COVID-19 pandemic.

Conclusions
High PASI 100 responses achieved with bimekizumab over 48 weeks were sustained through Week 96; secukinumab patients who switched to bimekizumab achieved similar responses by Week 96
