Merck (NYSE:MRK) announces that a Phase 3 clinical trial, KEYNOTE-355, evaluating the combination of Keytruda (pembrolizumab) and chemo in patients with metastatic triple-negative breast cancer (TNBC) whose tumors express PD-L1 (Combined Positive Score at least 10) met one of the dual primary endpoints, progression-free survival (PFS).
In a first-line setting, treatment with the Keytruda combo resulted in a statistically significant increase in PFS compared to chemo alone.
The trial will continue unchanged in order to assess the other primary endpoint of overall survival (OS).
