Pharmacology
Bimekizumab-bkzx is a humanized IgG1 monoclonal antibody that selectively binds IL-17A, IL-17F, and IL-17AF cytokines, inhibiting their interaction with the IL-17 receptor complex and suppressing the release of proinflammatory cytokines and chemokines.
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
