Full Name

A Phase II Study of Tazemetostat (EPZ-6438) (IND # 138671) in Recurrent or Persistent Endometrioid or Clear Cell Carcinoma of the Ovary, and Recurrent or Persistent Endometrioid Endometrial Adenocarcinoma

Description

This phase II trial studies how well tazemetostat works in treating patients with ovarian, primary peritoneal, or endometrial cancer that has come back. 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.

Eligibility

Inclusion Criteria
  • Pathologically (histologically or cytologically) proven diagnosis of recurrent/persistent ovarian, or peritoneal endometrioid/clear cell carcinoma, OR recurrent/persistent low grade (grade 1 or 2) endometrioid endometrial adenocarcinoma; primary ovarian tumors must be at least 50% endometrioid/clear cell morphology, or have histologically documented recurrence with at least 50% endometrioid/clear cell morphology; appropriate tissue sections must be available for histologic evaluation for central pathology review by National Research Group (NRG) Oncology
  • 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 prior platinum-based chemotherapeutic regimen for management of primary disease; unlimited prior hormonal therapy, targeted therapy or antiangiogenic therapy will be permitted
  • Patients must be 7 days to 6 weeks out from prior therapy:
    • Chemotherapy cytotoxic: At least 21 days since last dose of chemotherapy prior to first dose of tazemetostat
    • Chemotherapy nitrosoureas: At least 6 weeks since last dose of chemotherapy prior to first dose of tazemetostat
    • Chemotherapy non-cytotoxic (e.g. small molecule inhibitor): At least 7 days or five half-lives, whichever is shorter, since last dose of chemotherapy prior to first dose of tazemetostat
    • Monoclonal antibody(ies): At least 28 days since last dose of chemotherapy prior to first dose of tazemetostat
    • Immunotherapy: At least 21 days since last dose of chemotherapy prior to first dose of tazemetostat
    • Radiotherapy (RT): At least 28 days from last local site RT prior to first dose of tazemetostat
    • At least 21 days from stereotactic radiosurgery prior to first dose of tazemetostat
    • At least 28 days from craniospinal, > 50% radiation of pelvis or total body irradiation prior to first dose of tazemetostat
  • Appropriate stage for study entry based on the following diagnostic workup:
    • History/physical examination within 28 days prior to registration
    • Imaging of the chest, abdomen and pelvis within 30 days prior to registration
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2 within 28 days prior to registration
  • Within 14 days prior to registration: Absolute neutrophil count (ANC) >= 1,500/mcl
  • Within 14 days prior to registration: Hemoglobin (Hgb) >= 9 g/dL
  • Within 14 days prior to registration: Serum creatinine =< 1.5 x upper limit of normal (ULN)
  • Within 14 days prior to registration: Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3 x ULN
  • Within 14 days prior to registration: Total serum bilirubin level =< 1.5 x ULN; direct bilirubin =< ULN for subjects with total bilirubin > 1.5 x ULN (patients with isolated indirect bilirubin elevations and a history of Gilbert's syndrome are eligible)
  • The patient or a legally authorized representative must provide study-specific informed consent and authorization permitting release of personal health information prior to study entry
Exclusion Criteria
  • Prior treatment with an investigational EZH2 inhibitor
  • Patients whose circumstances do not permit completion of the study or the required follow-up
  • Patients who are unable to swallow pills
  • Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years, with the exception of those with a negligible risk of metastases or death, such as carcinoma in situ of the breast or cervix
  • Severe, active co-morbidity defined as follows:
    • Life expectancy < 3 months
  • Pregnant or lactating patients
  • Human immunodeficiency virus (HIV) positive patients on combination antiretroviral therapy are ineligible
