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.

Dabrafenib is a BRAF kinase inhibitor that targets mutated BRAF V600E, V600K, and V600D enzymes, inhibiting cell growth in BRAF V600 mutation-positive tumors.
