Keytruda is approved for the treatment of PD-L1 positive non-small cell lung cancer in patients who have reported disease progression after treatment with platinum-based chemotherapy, if the tumor has shown an abnormal ALK or EGFR gene but the ALK or EGFR inhibitors did not work.
Keytruda is also approved for patients with advanced melanoma with whom Yervoy (ipilimumab) did not work and wherein the tumor shows an abnormal BRAF gene (but the BRAF inhibitor did not work). Keytruda is also approved for patients with metastatic squamous cell carcinoma of head and neck, who have reported disease progression after the platinum-based chemotherapy.
Keytruda has received approval for the treatment of classical Hodgkin lymphoma in patients who have received three or more treatments or have undergone treatment (but the treatment didn’t work). Keytruda is also approved for the treatment of advanced urothelial carcinoma in patients who have undergone platinum-based chemotherapy, and for microsatellite instability-high tumor or mismatch repair deficient solid tumors, in the case of previously treated patients in whom the tumor has spread and cannot be removed by surgery.
