The phase III KEYNOTE-B21 trial evaluating Keytruda, Merck’s anti-PD-1 therapy, in combination with chemotherapy as adjuvant treatment, with or without radiotherapy, did not meet its primary endpoint of disease-free survival for the treatment of patients with newly diagnosed, high-risk endometrial cancer after surgery with curative intent.
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).
