On July 1, US Eastern time, Merck’s official website announced that it would voluntarily withdraw an indication previously approved by the FDA for Keytruda, specifically: for the treatment of recurrent locally advanced or metastatic gastric or gastroesophageal junction (GEJ) glands Cancer patients whose tumors express PD-L1 [combined positive score (CPS) ≥ 1]
The decision was made in consultation with the FDA after the Oncology Drug Advisory Committee evaluated Keytruda as a monotherapy for third-line gastric cancer indications on April 29, because Keytruda failed to meet its post-marketing proof of overall survival in a phase 3 study Period benefit requirements
The accelerated approval of Keytruda was first approved in September 2017.
Combined with trastuzumab and fluoropyrimidine/platinum-based chemotherapy, it is the first-line treatment for patients with HER2-positive locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma
