KEYTRUDA (pembrolizumab) is a programmed death receptor-1 (PD-1)-blocking antibody indicated:

Melanoma: for the treatment of patients with unresectable or metastatic melanoma; for the adjuvant treatment of adult and pediatric (12 years and older) patients with Stage IIB, IIC, or III melanoma following complete resection;

Non-Small Cell Lung Cancer (NSCLC): in combination with pemetrexed and platinum chemotherapy, as first-line treatment of patients with metastatic nonsquamous NSCLC, with no EGFR or ALK genomic tumor aberrations; in combination with carboplatin and either paclitaxel or paclitaxel protein-bound, as first-line treatment of patients with metastatic squamous NSCLC; as a single agent for the first-line treatment of patients with NSCLC expressing PD-L1 [Tumor Proportion Score (TPS) greater than or equal to 1 percent] as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberations, and is: Stage III where patients are not candidates for surgical resection or definitive chemoradiation, or metastatic; as a single agent for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS greater than or equal to 1 percent) as determined by an FDA-approved test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving Keytruda; for the treatment of patients with resectable (tumors greater than or equal to 4 cm or node positive) NSCLC in combination with platinum-containing chemotherapy as neoadjuvant treatment, and then continued as a single agent as adjuvant treatment after surgery; as a single agent, for adjuvant treatment following resection and platinum-based chemotherapy for adult patients with Stage IB (T2a greater than or equal to 4 cm), II, or IIIA NSCLC;

Classical Hodgkin Lymphoma (cHL): for the treatment of adult patients with relapsed or refractory cHL; for the treatment of pediatric patients with refractory cHL, or cHL that has relapsed after 2 or more lines of therapy;

Primary Mediastinal Large B-Cell Lymphoma (PMBCL): for the treatment of adult and pediatric patients with refractory PMBCL, or who have relapsed after 2 or more prior lines of therapy;

Urothelial Cancer: in combination with enfortumab vedotin, for the treatment of adult patients with locally advanced or metastatic urothelial cancer; as a single agent for the treatment of patients with locally advanced or metastatic urothelial carcinoma who: are not eligible for any platinum-containing chemotherapy, or who have disease progression during or following platinum-containing chemotherapy or within 12 months of neoadjuvant treatment with platinum-containing chemotherapy; as a single agent for the treatment of patients with Bacillus Calmette-Guerin (BCG)-unresponsive, high-risk, non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors who are ineligible for or have elected not to undergo cystectomy;

Cervical Cancer: In combination with chemoradiotherapy, for the treatment of patients with FIGO 2014 Stage III-IVA cervical cancer; in combination with chemotherapy, with or without bevacizumab, for the treatment of patients with persistent, recurrent or metastatic cervical cancer whose tumors express PD-L1 (CPS greater than or equal to 1) as determined by an FDA-approved test; as a single agent for the treatment of patients with recurrent or metastaticcervical cancer with disease progression on or after chemotherapy whose tumors express PD-L1 (CPS greater than or equal to 1) as determined by an FDA-approved test;
