Pharmacology
Secukinumab is a human IgG1 monoclonal antibody that selectively binds to the IL-17A cytokine and inhibits its interaction with the IL-17 receptor, suppressing the release of proinflammatory cytokines and chemokines involved in inflammatory and immune responses.
Brodalumab is a human monoclonal IgG2 antibody that selectively binds to IL-17RA and inhibits its interactions with IL-17 family cytokines (IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer, IL-25), thereby blocking IL-17 cytokine-induced pro-inflammatory responses.
