Keytruda (pembrolizumab) [package insert]. FDA. The U.S. Food and Drug Administration granted approval to pembrolizumab in combination with chemotherapy for the neoadjuvant treatment, and then pembrolizumab continued as a single agent as adjuvant treatment after surgery, of patients with high-risk early-stage triple negative breast cancer (TNBC). This indication is based on KEYNOTE-522 (NCT03036488), a randomized (2:1), multicenter, double-blind, placebo-controlled trial where the chemotherapy regimen consisted of carboplatin, paclitaxel, doxorubicin, and cyclophosphamide.
