Pharmacology
Cemiplimab-rwlc is a recombinant human IgG4 monoclonal antibody (PD-1 inhibitor) that binds to PD-1 and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response.
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.
