Merck & Co. Tuesday said a pivotal Phase 3 study of its
cancer drug Keytruda in combination with chemotherapy met a primary
endpoint of overall survival in metastatic triple-negative breast
cancer.
The Kenilworth, N.J., drugmaker said the combination showed a
statistically significant and clinically meaningful improvement in
overall survival compared with chemotherapy alone in patients whose
tumors expressed PD-L1 with a combined positive score of at least
10.
Merck said Keytruda is the first anti-PD-1 therapy in
combination with chemotherapy to show statistically significant
overall survival for that patient population. The company
previously reported that the combination had shown significantly
improved progression-free survival.
Merck is studying Keytruda, a cancer drug that harnesses a
patient's immune system to fight tumors, across multiple settings
and stages of triple-negative breast cancer, the subtype with the
worst survival prognosis.
