Bimekizumab Investigational for Psoriasis
Bimekizumab is a monoclonal antibody designed to potently and selectively neutralize both interleukin (IL)-17A and IL-17F cytokines. In the Phase 2b BE ABLE study, the safety, efficacy, pharmacokinetics and pharmacodynamics of bimekizumab were compared with placebo in adult patients with moderate to severe chronic plaque psoriasis.3
The study met the primary objective of establishing dose response for bimekizumab and demonstrated significant efficacy compared with placebo. At Week 12, 79% of bimekizumab-treated patients achieved at least 90% skin clearance in the Psoriasis Area and Severity Index (PASI90). A secondary efficacy objective was complete skin clearance at Week 12 as measured by PASI100. Up to 60% of bimekizumab-treated patients achieved this endpoint.
The safety profile of bimekizumab showed no new safety signals. The most common adverse events observed were nasopharyngitis and upper-respiratory tract infection. Phase 3 studies are currently planned.
