Inc. (NYSE:MRK) is one of the best low risk stocks to buy in 2026
On May 18, Merck announced that its pivotal Phase 3 TroFuse-005 trial evaluating sacituzumab tirumotecan (sac-TMT) met its dual primary endpoints of overall survival/OS and progression-free survival/PFS in patients with advanced or recurrent endometrial cancer. The investigational TROP2-directed antibody-drug conjugate, developed in collaboration with Kelun-Biotech, is the first global Phase 3 trial to show statistically significant improvements in OS and PFS compared to standard chemotherapy in this patient population. The pre-specified interim analysis demonstrated clinically meaningful efficacy against the physician’s choice of treatment (doxorubicin or paclitaxel) for individuals whose disease progressed following platinum-based chemotherapy and anti-PD-1/L1 immunotherapy.
The trial also achieved its key secondary endpoint of objective response rate, maintaining a safety profile consistent with prior sac-TMT studies with no new safety signals.
