Pharmacology
Pembrolizumab is a PD-1 blocking antibody that releases PD-1 pathway-mediated inhibition of the immune response by preventing the interaction of PD-1 with its ligands PD-L1 and PD-L2, thereby restoring anti-tumor immune response.
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.
