| Pembrolizumab | Keytruda | MK-3475 | Immune Checkpoint Inhibitor 150 PD-L1/PD-1 antibody 137 | Keytruda (pembrolizumab) is an antibody against PD-1 that activates T-cell mediated anti-tumor immune response (PMID: 25977344). Keytruda (pembrolizumab) is approved in melanoma, SCLC, HNSCC, classical Hodgkin Lymphoma, PMBL, urothelial carcinoma, HCC, Merkel cell carcinoma, NMIBC, cutaneous SCC, MSI-H or dMMR or TMB high advanced solid tumors, NSCLC and CD274 (PD-L1)-positive NSCLC, esophageal SCC, cervical cancer, HNSCC, and TNBC, in combination with platnum-based chemo in NSCLC, with pemetrexed and platinum in pleural mesothelioma and non-sNSCLC with no EGFR or ALK mutations, with carboplatin and paclitaxel/nab-paclitaxel in sNSCLC, with axitinib or lenvatinib in RCC, with lenvatinib in endometrial carcinoma that is not MSI-H or dMMR, with platinum and fluoropyrimidine-based chemo for esophageal or gastroesophageal carcinoma, with Herceptin (trastuzumab), fluoropyrimidine- and platinum-containing chemo for CD274 (PD-L1)-positive, HER2-positive gastric or GEJ adenocarcinoma, with fluoropyrimidine- and platinum-containing chemo for HER2-negative gastric or GEJ adenocarcinoma, with platinum-based chemotherapy, with or without bevacizumab, for patients with CD274 (PD-L1)-positive cervical cancer, with gemcitabine and cisplatin for biliary tract cancer, with chemoradiation for cervical cancer, with carboplatin and paclitaxel for endometrial carcinoma, with paclitaxel with or without bevacizumab for epithelial ovarian, Fallopian tube, and peritonium cancer (FDA.gov). |

| MLH1 negative | Advanced Solid Tumor | sensitive | Pembrolizumab | FDA approved | Actionable | In a combined analysis of 5 trials that supported FDA approval, Keytruda (pembrolizumab) therapy resulted in an objective response rate of 39.6% (59/149) in advanced solid tumor patients with high levels of microsatellite instability (MSI-H) or deficient mismatch repair (dMMR, often defined by the loss of MLH1, PMS2, MSH2, or MSH6 expression by IHC) (PMID: 30787022; NCT01876511, NCT02460198, NCT01848834, NCT02054806, NCT02628067). | detail... 30787022 |
| MSH6 negative | colorectal cancer | sensitive | Pembrolizumab | FDA approved | Actionable | In a Phase III (KEYNOTE-177) trial that supported FDA approval, Keytruda (pembrolizumab) treatment as first-line therapy significantly improved median progression-free survival (16.5 vs 8.2 mo, HR=0.60, p=0.0002) compared to chemotherapy in patients with advanced microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR, often defined by the loss of MLH1, PMS2, MSH2, or MSH6 expression by IHC) colorectal cancer (PMID: 33264544; NCT02563002). | 33264544 detail... |

| MLH1 negative | endometrial carcinoma | sensitive | Pembrolizumab | FDA approved - On Companion Diagnostic | Actionable | In a Phase II trial (KEYNOTE-158) that supported FDA approval, Keytruda (pembrolizumab) treatment resulted in an objective response rate of 48% (38/79, 11 complete responses, 27 partial responses) in patients with advanced microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR, often defined by the loss of MLH1, PMS2, MSH2, or MSH6 expression by IHC) endometrial carcinoma, with a median progression-free survival of 13.1 months (PMID: 34990208; NCT02628067). | detail... 34990208 detail... |
