Immunotherapy with nivolumab (Opdivo) is now approved in the United States for first-line use in the treatment of unresectable advanced or metastatic esophageal squamous cell carcinoma (ESCC).
The new approval for the drug, a programmed cell death ligand-1 (PD-L1) inhibitor, is for use in this patient population regardless of PD-L1 status. The indication also specifies that nivolumab is to be used together with chemotherapy (with a fluoropyrimidine- and platinum-containing regimen) or in combination with ipilimumab (Yervoy), an immunotherapy with a different mechanism of action.
