Avelumab (Bavencio) is a programmed death ligand-1 (PD-L1) blocking antibody, first approved for marketing by the U.S. FDA in 2017. As an immune checkpoint inhibitor, it activates the immune system to fight against tumors by blocking the PD-L1/PD-1 signaling pathway.

The core indication of avelumab is for the treatment of metastatic Merkel cell carcinoma (MCC) in adult and pediatric patients 12 years of age and older.
This indication was approved through the accelerated approval pathway based on tumor response rate and duration of response. Its continued approval may be contingent upon the verification and description of clinical benefit in confirmatory trials.
