Pharmacology

Durvalumab is a human IgG1 kappa monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, releasing the inhibition of immune responses without inducing antibody-dependent cell-mediated cytotoxicity.

Bevacizumab-bvzr binds VEGF and prevents its interaction with receptors Flt-1 and KDR on the surface of endothelial cells, inhibiting endothelial cell proliferation, new blood vessel formation, and metastatic disease progression.
