Merck’s Keytruda Approved for Esophageal Carcinoma
FDA has approved Merck’s Keytruda (pembrolizumab) in combination with platinum and fluoropyrimidine-based chemotherapy for patients with metastatic or locally advanced esophageal or gastroesophageal (tumors with epicenter 1 to 5 centimeters above the gastroesophageal junction) carcinoma who are not candidates for surgical resection or definitive chemoradiation. The approval was based on data from the KEYNOTE 590 (NCT03189719) trial, which demonstrated a statistically significant improvement in overall survival (OS) and progression-free survival (PFS), according to an FDA release. Median OS was 12.4 months for the pembrolizumab arm versus 9.8 months for the chemotherapy arm, and median PFS was 6.3 and 5.8 months, respectively.
