The U.S. Food and Drug Administration (FDA) has approved KEYTRUDA, Merck’s anti-PD-1 therapy, in combination with chemotherapy for the treatment of patients with locally recurrent unresectable or metastatic triple-negative breast cancer (TNBC) whose tumors express PD-L1 (Combined Positive Score [CPS] ≥10).
“Approximately 15-20% of patients with breast cancer are diagnosed with triple-negative breast cancer, which is a difficult-to-treat and aggressive cancer,” said Dr. Hope Rugo, director of Breast Oncology and Clinical Trials Education, University of California San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center. “Notably, in KEYNOTE-355, KEYTRUDA was combined with three different chemotherapy regimens: paclitaxel, nab-paclitaxel or gemcitabine and carboplatin. The approval of KEYTRUDA in combination with chemotherapy gives physicians an important new option for appropriate patients.”
