The FDA has approved pembrolizumab (Keytruda) for the treatment of patients with PD-L1–positive recurrent or advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma who have received 2 or more lines of chemotherapy, including fluoropyrimidine- and platinum-containing chemotherapy, and, if appropriate, HER2/neu-targeted therapy.
Pembrolizumab is approved for several indications, including as a treatment for patients with lung cancer, melanoma, Hodgkin lymphoma, and other types of cancer. In mid-May, the FDA granted an accelerated approval to pembrolizumab as a treatment for patients without other options with unresectable or metastatic, MSI-H or mismatch repair deficient (dMMR) solid tumors. This was in addition to those with MSI-H or dMMR colorectal cancer following progression on a fluoropyrimidine, oxaliplatin, and irinotecan.
