Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The researchers are doing this study to evaluate the use of circulating tumor DNA (ctDNA) testing in making treatment decisions for advanced/recurrent endometrial cancer that has a change (mutation) in the mismatch repair deficient (MMR-D) gene or microsatellite instability high (MSI-H) gene. The researchers will see how doctors and their patients use the results of ctDNA testing after 1 year of standard chemotherapy and immune checkpoint inhibitor (ICI) treatment to decide whether to continue maintenance ICI treatment past 1 year. The researchers will also look at the health outcomes of people in this study (for example, whether they are cancer free at the end of their participation in the study).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ctDNA-negative group

Participants in this group will have negative ctDNA test results at 1 year after they start standard treatment. (Negative results indicate that no cancer DNA is detected in their blood.) Participants in this group will decide with their doctor if they want to stop standard maintenance ICI treatment.

Group Type EXPERIMENTAL

ctDNA Testing

Intervention Type GENETIC

Patients will undergo ctDNA sampling at the 1-year timepoint using the commercially available Natera SignateraTM test.

Intervention Type OTHER

ctDNA-positive group

Participants in this group will have positive ctDNA test results at 1 year after they start standard treatment. (Positive results indicate that cancer DNA is detected in their blood.) Participants in this group will continue receiving standard treatment with their doctor.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients must have pathologically confirmed endometrial cancer
* Patients with advanced endometrial cancer
* Stage III with residual disease
* Stage IV
* Recurrent endometrial cancer after adjuvant therapy only
* Patients can have primary or planned interval surgery
* MMR-D on immunohistochemistry OR MSI-H using any commercially available test
* Patients with treated brain metastases are eligible if follow up brain imaging after CNS directed therapy shows no evidence of progression.
* Eligible for standard of care chemotherapy with immune checkpoint inhibitor per treating investigator with no clinical contraindications
* For the up to 10 patients who are allowed to enroll after C1D1 of standard of care treatments, they need to be on treatment with no clinical evidence of disease progression.

* Patients may have received prior hormonal therapy for treatment of endometrial cancer.
* Patients may not have received prior therapy with an anti-PD-1, anti-PD-L1 or anti-CTLA-4 therapeutic antibody or other similar agents.

* Except for the up to 10 patients who are allowed to enroll after C1D1 of standard of care treatments (chemotherapy and/or immune checkpoint inhibitors) per protocol.
* Age ≥ 18
* Not Pregnant and Not Nursing
