MLH1 negative | biliary tract cancer | sensitive | Pembrolizumab | Guideline | Actionable | Keytruda (pembrolizumab) is included in the Pan-Asian Guidelines Adaptation (PAGA) for patients with mismatch repair-deficient (dMMR, defined by the loss of MLH1, PMS2, MSH2, or MSH6 expression by IHC) biliary tract cancer who have progressed on or are intolerant of non-immune checkpoint inhibitor therapies (PMID: 39232586; ESMO.org). | detail... 39232586 |
MLH1 negative | biliary tract cancer | sensitive | Pembrolizumab | Phase II | Actionable | In a Phase II trial (KEYNOTE-158), Keytruda (pembrolizumab) treatment resulted in an objective response rate of 40.9% (9/22, 3 complete responses and 6 partial responses), a duration of response of 30.5 mo, a median progression-free survival of 4.2 mo, and a median overall survival of 19.4 mo in patients with microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR, defined by the loss of MLH1, PMS2, MSH2, or MSH6 expression by IHC) biliary tract cancer (PMID: 35680043; NCT02628067). | 35680043 |
