This phase II trial studies how well tazemetostat works in treating patients with ovarian or endometrial cancer that has come back (recurrent). Drugs used in chemotherapy, such as tazemetostat, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
Name: Laboratory Biomarker Analysis
Description: Correlative studiesType: OtherTreatment (tazemetostat)
Name: Tazemetostat
Description: Given POType: DrugTreatment (tazemetostat)
Description: Will be characterized by quartiles and the median of the distribution with confidence intervals. Kaplan-Meier plots will show an estimate of the survival function for these populations.
Measure: Progression-free survival Time: From study entry to time of progression or death, whichever occurs first, assessed up to 5 yearsDescription: Will be characterized by quartiles and the median of the distribution with confidence intervals. Kaplan-Meier plots will show an estimate of the survival function for these populations.
Measure: Overall survival Time: From study entry to time of death or the date of last contact, assessed up to 5 yearsDescription: Associations between BAF250a and ARID1A mutations may be examined with contingency table analysis (e.g. potentially including Chi-square analyses or Spearman's correlation).
Measure: ARID1A mutational status Time: Up to 6 monthsDescription: Associations between BAF250a and ARID1A mutations may be examined with contingency table analysis (e.g. potentially including Chi-square analyses or Spearman's correlation).
Measure: BAF250a expression by immunohistochemistry Time: Up to 6 monthsSingle Group Assignment

JAK2 V617F) observed in cytogenetic testing and deoxyribonucleic acid (DNA) sequencing - A prior history of T-cell lymphoblastic lymphoma (T-LBL)/T-cell acute lymphoblastic leukemia (T-ALL) - Severe, active co-morbidity per the treating investigator's discretion - Pregnant or lactating patients - Known human immunodeficiency virus (HIV) positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with tazemetostat; in addition, treatments involved in this protocol may be immunosuppressive, increasing the risk of lethal infections in this patient population - Treatment with strong inhibitors or inducers of CYP3A within 14 days of registration and during the study treatment Inclusion Criteria: - Pathologically (histologically or cytologically) proven diagnosis of recurrent or persistent ovarian endometrioid or clear cell carcinoma, OR recurrent or persistent endometrioid endometrial adenocarcinoma; patients with recurrent endometrial cancer must have mismatch repair (MMR) immunohistochemistry completed; if they are found to be mismatch repair deficient, they should be offered treatment with immune checkpoint inhibition before consideration for treatment on trial; primary ovarian tumors must be at least 50% endometrioid or clear cell morphology, or have histologically documented recurrence with at least 50% endometrioid or clear cell morphology; institutional pathology reports must be provided indicating at least 50% endometrioid or clear cell morphology for ovarian tumors (primary or recurrent lesions) - All patients must have measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1; measurable disease 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 computed tomography (CT), magnetic resonance imaging (MRI) or caliper measurement by clinical exam; or >= 20 mm when measured by chest x-ray; lymph nodes must be > 15 mm in short axis when measured by CT or MRI - Patients must have had at least one, but no more than 3, prior cytotoxic regimens for management of primary disease; unlimited prior hormonal therapy, targeted therapy (including immunotherapy) or antiangiogenic therapy will be permitted - Patients must have completed prior therapy: - Chemotherapy: cytotoxic - At least 28 days since last dose of chemotherapy prior to registration. --- V617F ---
