NRG Oncology NRG-GY018 Study Demonstrates Significantly Improved Progression Free Survival Outcomes for Women with Advanced or Recurrent Endometrial Cancer with the Addition of Pembrolizumab to Chemotherapy
February 03 2023
NRG Oncology Phase III clinical trial, NRG-GY018, evaluating pembrolizumab in combination with standard of care chemotherapy (carboplatin and paclitaxel) met its primary endpoint of progression free survival (PFS) for the treatment of patients with stage III-IV or recurrent endometrial carcinoma, regardless of mismatch repair status. A pre-specified interim analysis, conducted by an independent Data Monitoring Committee, demonstrates that pembrolizumab in combination with chemotherapy has a statistically significant and clinically meaningful improvement in PFS compared with chemotherapy alone in both study cohorts, mismatch repair deficient (dMMR) and mismatch repair proficient (pMMR). The full results of this trial will be presented at an upcoming scientific conference.
NRG-GY018, a randomized, blinded, placebo-controlled study, accrued 819 women with stage III-IV or recurrent endometrial cancer. Two independent cohorts were evaluated, patients with endometrial cancers that are dMMR and patients with endometrial cancers that are pMMR. Patients were randomly assigned to receive pembrolizumab combined with carboplatin and paclitaxel (for a planned six, 3-week cycles), followed by pembrolizumab maintenance (for up to fourteen, 6 week cycles) or placebo combined with carboplatin and paclitaxel, followed by placebo maintenance.
