FDA Approves Merck’s Keytruda for Some Breast Cancers
FDA has approved Merck’s Keytruda (pembrolizumab) for treating patients with high-risk early-stage triple-negative breast cancer (TNBC) in combination with chemotherapy as neoadjuvant treatment and then continued as a single agent as adjuvant treatment after surgery. The company says the approval is based on the Phase 3 KEYNOTE-522 trial that showed Keytruda in combination with carboplatin and paclitaxel, followed by doxorubicin or epirubicin and cyclophosphamide before surgery and continued as a single agent after surgery significantly prolonged event-free survival versus the same neoadjuvant regimens alone in patients with previously untreated stage 2 or 3 TNBC. The company says Keytruda is now approved in the U.S. for 30 indications.
