Merck & Company IncKEYTRUDA met primary endpoint in Phase 3 endometrial cancer trial, showing significant benefit over chemotherapy.

Merck reported that its immunotherapy KEYTRUDA met the primary endpoint of progression-free survival in the Phase 3 KEYNOTE-C93 trial for advanced or recurrent endometrial cancer. The company highlighted this as the first time a PD-1 inhibitor has shown a statistically significant benefit over platinum chemotherapy in this patient population. The data are described as a high-impact development for Merck's oncology portfolio, with potential implications for future regulatory filings. KEYTRUDA remains central to Merck's oncology strategy, and this latest readout adds another clinical result to a program that already spans multiple tumor types. The outcome reinforces how heavily Merck relies on KEYTRUDA, which analysts flag in connection with the future loss of exclusivity, so further concentration in this product could challenge the goal of rebalancing earnings across newer launches.
