Merck (MRK) Gets FDA's Priority Review for Another Keytruda sBLA

Read MoreHide Full Article

Merck & Co., Inc. (MRK - Free Report) announced that that the FDA has accepted its supplemental biologics license application (sBLA) seeking approval of its blockbuster anti-PD-1 therapy, Keytruda, for newly diagnosed esophageal and gastroesophageal junction (“GEJ”) cancer. The company is seeking an approval for Keytruda in combination with platinum and fluoropyrimidine-based chemotherapy for the first-line treatment of patients with locally advanced unresectable/metastatic esophageal and GEJ cancer.

With the FDA granting a priority review to the sBLA, a decision from the regulatory body is expected on Apr 13, 2021.

The sBLA was based on data from the pivotal phase III KEYNOTE-590 study which evaluated Keytruda plus chemotherapy for treating esophagus and GEJ cancer in the first-line setting. Data from the study showed that treatment with the Keytruda combo led to significant improvements in overall survival and progression-free survival – the primary endpoints, as compared to patients who received only chemotherapy regardless of their PD-L1 expression status and tumor histology.

Per the company, despite current available treatments, patients with esophageal and GEJ cancer in the first-line setting often face an aggressive disease with a poor prognosis. If approved, the Keytruda combo can become a new treatment option for the given patient population.

Notably, Keytruda as a monotherapy is already approved for the second-line treatment of recurrent locally advanced/metastatic squamous cell carcinoma of the esophagus in patients whose tumors express PD-L1 in the United States, China and Japan.

Shares of Merck have declined 12.2% so far this year against the industry’s increase of 2.2%.
