Bimekizumab for the treatment of hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a painful, inflammatory dermatosis involving recurrent abscesses, nodules and tunnels in intertriginous regions. Biologics and other immunomodulators have significantly expanded the treatment options available for HS. Bimekizumab is a monoclonal antibody targeting both interleukin-17A and interleukin-17F, key mediators of inflammation, that is already approved for psoriasis, psoriatic arthritis and axial spondylarthritis. It is currently pending FDA review for HS treatment but has already received marketing authorization for this indication in Europe. This review aims to explore drug-specific characteristics of bimekizumab including its mechanism of action, pharmacokinetics and pharmacodynamics and the current state of the literature regarding its use in HS such as safety, efficacy and dosing, while highlighting its implications in clinical practice. Recent Phase II and III trial data demonstrating positive efficacy and safety profiles in the treatment of HS will also be detailed.
