Pharmacology
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.
Infliximab-dyyb is a chimeric IgG1kappa monoclonal antibody TNF-alpha antagonist that neutralizes the biological activity of TNFalpha by binding with high affinity to soluble and transmembrane forms of TNFalpha, inhibiting receptor binding and downstream proinflammatory cytokine activity in RA, CD, UC, AS, PsA, and Ps.
