Merck & Company IncKeytruda Phase 3 trial met primary endpoint in endometrial cancer, showing improved progression-free survival.

Merck announced that the Phase 3 KEYNOTE-C93 trial evaluating KEYTRUDA met its primary endpoint of progression-free survival in patients with mismatch repair deficient advanced or recurrent endometrial cancer. The randomized, open-label trial compared KEYTRUDA monotherapy against carboplatin plus paclitaxel, with dual primary endpoints of progression-free survival and overall survival. A pre-specified interim analysis showed improvement in overall survival, though the data were not mature, and also demonstrated a clinically meaningful overall response rate, complete response rate, and duration of response for KEYTRUDA. Dr. Brian Slomovitz, the study's overall principal investigator, noted this is the first Phase 3 trial of a PD-1 inhibitor to show improved progression-free survival compared to platinum doublet chemotherapy as monotherapy in the frontline setting, potentially offering a chemo-free option. In pre-market trading, Merck shares rose 2.04 percent to $123.26.
