Study Details

Study Description

Brief Summary

This phase II Pediatric MATCH trial studies how well tazemetostat works in treating patients with brain tumors, solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have come back (relapsed) or do not respond to treatment (refractory) and have EZH2, SMARCB1, or SMARCA4 gene mutations. Tazemetostat may stop the growth of tumor cells by blocking EZH2 and its relation to some of the pathways needed for cell proliferation.

Detailed Description

PRIMARY OBJECTIVE:
  1. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with tazemetostat with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphoma or histiocytic disorders that harbor gain of function mutations in EZH2, or loss of function mutations in the SWI/SNF complex subunits SMARCB1 or SMARCA4 at a dose of 520 mg/m2/dose twice daily for patients without any CNS involvement or 1200 mg/m2/dose orally twice daily for patients with CNS involvement.
SECONDARY OBJECTIVES:
  1. To estimate the progression-free survival in pediatric patients treated with tazemetostat that harbor gain of function mutations in EZH2, or loss of function mutations in the SWI/SNF complex subunits SMARCB1 or SMARCA4.

  2. To obtain information about the tolerability of tazemetostat in children with relapsed or refractory cancer.

EXPLORATORY OBJECTIVES:
  1. To evaluate other biomarkers as predictors of response to tazemetostat and specifically, whether tumors that harbor different missense mutations or fusions will demonstrate differential response to tazemetostat treatment.

  2. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).

OUTLINE:

Patients receive tazemetostat orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

  • Outcome Measures

    Primary Outcome Measures

    1. Objective response rate (ORR) [Up to 2 years]

      ORR will be defined as complete response + partial response and assessed by Response Evaluation Criteria in Solid Tumors (RECIST). Will be calculated as the percent of evaluable patients who are responders, and confidence intervals will be constructed using the Wilson score interval method.

    Secondary Outcome Measures

    1. Progression-free survival (PFS) [From start of subprotocol treatment to time of progression or death, whichever occurs first, assessed for up to 2 years]

      PFS along with the confidence intervals will be estimated using the Kaplan-Meier method.

    Other Outcome Measures

    1. Biomarker predictors of response to tazemetostat [Up to 2 years]

      Will evaluate other biomarkers as predictors of response to tazemetostat and specifically, whether tumors that harbor different missense mutations or fusions will demonstrate differential response to tazemetostat treatment. Will be performed and will be summarized with simple summary statistics and will be descriptive in nature.

    2. Change in tumor genomics [Up to 2 years]

      To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid. Will be performed and will be summarized with simple summary statistics and will be descriptive in nature.
