The phase III KEYNOTE-522 trial evaluating Keytruda, Merck’s anti-PD-1 therapy, met its overall survival endpoint, in combination with chemotherapy as pre-operative treatment and then continuing as a single agent after surgery for the treatment of patients with high-risk early-stage triple-negative breast cancer.
FDA granted traditional approval to Merck’s pembrolizumab (Keytruda) with trastuzumab, fluoropyrimidine- and platinum-containing chemotherapy for the first-line treatment of adults with locally advanced unresectable or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma whose tumors express PD-L1 (CPS ≥1).
