Wednesday, November 13, 2019 The CCTG ENC1 study, A Phase III Randomized, Placebo-Controlled Study of Pembrolizumab (MK-3475, NSC#776864) in Addition to Paclitaxel and Carboplatin for Measurable Stage III or IVA, Stage IVB or Recurrent Endometrial Cancer, has been centrally activated and open to accrual. This phase III trial studies how well the combination of pembrolizumab, paclitaxel and carboplatin, works compared with paclitaxel and carboplatin alone in treating patients with endometrial cancer that is stage III or IV, or has come back (recurrent). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Paclitaxel and carboplatin are chemotherapy drugs used as part of the usual treatment approach for this type of cancer. This study aims to assess if adding immunotherapy to these drugs is better or worse than the usual approach for treatment of this cancer. Eligibility: women with measurable stage III, measurable stage IVA, stage IVB (with or without measurable disease) or recurrent (with or without measurable disease) endometrial cancer. Objectives: Primary Objective: To evaluate the efficacy of pembrolizumab in combination with paclitaxel and carboplatin in patients with advanced stage (measurable stage III or IVA), stage IVB and recurrent endometrial cancer. Efficacy will be determined via investigator assessed progression free survival (PFS) in two distinct populations referred to as proficient and deficient mismatch repair (pMMR and dMMR).
