First-line Carboplatin and Paclitaxel in Combination With Pembrolizumab, Followed by Maintenance Pembrolizumab With or Without Nesuparib, in Patients With Newly Diagnosed Advanced or Recurrent MMR-proficient (pMMR) Endometrial Cancer

Summary

The goal of this study is listed below. Part A (Safety Run-in Phase) : To determine feasibility of pembrolizumab and nesuparib combination as maintenance therapy in patients with MMR-proficient advanced and recurrent endometrial cancer. Feasibility is defined as a dose-limiting toxicity (DLT) rate less than or equal to 33%. Part B (Randomization Phase) : To evaluate the efficacy of pembrolizumab and nesuparib combination/ pembrolizumab monotherapy as maintenance therapy in patients with MMR-proficient advanced stage and recurrent endometrial cancer. Efficacy will be assessed by investigator assessed progression free survival (PFS) as assessed by RECIST 1.1.
