Use in Cancer
Pembrolizumab is approved to treat:
- Gastric (stomach) cancer or gastroesophageal junction cancer that is recurrent and locally advanced or metastatic. It is used in patients whose cancer has the PD-L1 protein and whose disease got worse during or after two or more types of treatment including a fluoropyrimidine and platinum chemotherapy and, in some cases, HER2/neu targeted therapy.
- Hodgkin lymphoma in adults and children. It is used in patients whose disease is refractory (does not respond to treatment) or has relapsed after at least three other types of treatment.
- Melanoma that cannot be removed by surgery or that has metastasized (spread to other parts of the body).
- Microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) cancer that is metastatic and cannot be removed by surgery. It is used in adults and children for:
- Solid tumors that have gotten worse after other treatment or that cannot be treated with other therapies.
- Colorectal cancer that has gotten worse after treatment with a fluoropyrimidine, oxaliplatin, and irinotecan.
- Non-small cell lung cancer that has metastasized. It is used:
- With pemetrexed and carboplatin as first-line treatment in patients with nonsquamous disease.
- As first-line treatment in patients whose cancer has the PD-L1 protein and does not have a mutation in the epidermal growth factor receptor (EGFR) gene or anaplastic lymphoma kinase (ALK) gene.
- In patients whose cancer has the PD-L1 protein and got worse during or after treatment with platinum chemotherapy. Patients whose cancer has EGFR or ALK gene mutations should receive pembrolizumab only if their disease got worse after treatment with an FDA-approved therapy for these mutations.
- Squamous cell carcinoma of the head and neck that has metastasized or recurred (come back) in patients whose disease got worse during or after treatment with platinum chemotherapy.
- Urothelial carcinoma (a type of bladder cancer) that is locally advanced or has metastasized. It is used in patients who cannot be treated with cisplatin or whose disease got worse during or after platinum chemotherapy.
Pembrolizumab is also being studied in the treatment of other types of cancer.
