Summary

This study takes investigator-assessed Progression-Free Survival (PFS) as the primary endpoint, with plans to enroll 140 patients with advanced recurrent/metastatic endometrial cancer in a 1:1 ratio, randomized into an experimental group and a control group. The aim is to evaluate the efficacy and safety of Adebelimab (PD-L1) combined with Carboplatin/Paclitaxel treatment, followed by maintenance therapy with or without Apatinib in patients with advanced recurrent/metastatic endometrial cancer. Additionally, based on molecular testing results, the study will explore the PFS and Overall Survival (OS) of patients with Deficient Mismatch Repair/Microsatellite Instability-High(dMMR/MSI-H) and Proficient Mismatch Repai/Microsatellite Stability (pMMR/MSS) endometrial cancer, providing new precision treatment options for patients with recurrent and metastatic endometrial cancer.

Conditions

• Recurrent/Metastatic Endometrial Cancer
