Abstract
INTRODUCTION
Interleukin (IL)-17 is critical in the pathogenesis of psoriasis and psoriatic arthritis (PsA) with most data suggesting that IL-17A alone was the key cytokine. However, in vitro and in vivo studies have suggested dual blockade of IL-17A and IL-17 F may be more effective than IL-17 A blockade alone. Bimekizumab is the first human monoclonal antibody to exert simultaneous specific inhibition of IL-17A and IL-17 F, and has been studied in several phase II/III trials for psoriasis and PsA.
AREAS COVERED
Bimekizumab is not currently licensed for use. A literature search identified clinical trials examining the efficacy and safety of bimekizumab for psoriasis and PsA, and these were critically appraised.
EXPERT OPINION
Clinical trials of bimekizumab have been promising, demonstrating a rapid onset of response and superior efficacy compared to three currently licensed biologics: secukinumab, ustekinumab, and adalimumab. Bimekizumab maintains a high level of efficacy with maintenance dosing intervals of 8 weeks, compared with 4 weeks for currently licensed IL-17A antagonists. No unexpected adverse events have been identified, although mild-to-moderate fungal infections occur in approximately 10%. Studies over longer time periods involving additional active comparators would be valuable in further defining the role of bimekizumab amongst currently available treatments.
