New combo therapy shows promise for advanced uterine cancer
NCT ID NCT03517449
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a combination of two drugs, lenvatinib and pembrolizumab, against standard chemotherapy in 827 people with advanced endometrial cancer that had worsened after initial treatment. The goal was to see if the combo could delay cancer growth and extend life. Results showed the combination improved how long patients lived without their cancer getting worse.
