About this study

This phase III trial compares the effect of bevacizumab in combination with carboplatin, paclitaxel and pembrolizumab to the usual treatments of carboplatin and paclitaxel with or without pembrolizumab in treating patients with stage III, IVA or IVB mismatch repair protein proficient (pMMR) and TP53 mutated endometrial cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has come back after a period of improvement (recurrent). Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Adding bevacizumab to the combination of carboplatin, paclitaxel and pembrolizumab may be more effective than the usual treatment combinations of carboplatin and paclitaxel with or without pembrolizumab in treating patients with advanced or recurrent pMMR and TP53 mutated endometrial cancer.

You may qualify if…

✓ Documentation of disease:
✓ Stage III and stage IVA endometrial cancers (with measurable disease),
✓ Stage IVB endometrial cancer (with or without measurable disease), or
✓ Recurrent endometrial cancer (with or without measurable disease)
✓ In patients with measurable disease, lesions will be defined and monitored by RECIST 1.1. Measurable disease (RECIST 1.1) is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be ≥ 10 mm when measured by CT or MRI. Lymph nodes must be ≥ 15 mm in short axis when measured by CT or MRI
✓ Histologic confirmation of the original primary tumor is required (submission of pathology report\[s\] is required). Patients with the following histologic types are eligible: endometrioid, serous, dedifferentiated/undifferentiated, clear cell, mixed epithelial, carcinosarcoma, adenocarcinoma not otherwise specified (N.O.S.)
✓ Patients must have:
✓ Tumoral mismatch repair proficient (pMMR) disease as assessed by immunohistochemistry (IHC) AND
