NCT ID NCT03016338

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests two drugs—niraparib and TSR-042 (dostarlimab)—in 51 women with recurrent endometrial cancer that has progressed after platinum chemotherapy. The goal is to see if these drugs can shrink or stabilize tumors. Niraparib blocks a protein that helps cancer cells repair themselves, while TSR-042 boosts the immune system to attack cancer.
