NCT03213665

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.

Outcome Measures

Primary Outcomes (1)

  • Objective Response Rate (ORR)

    ORR will be defined as complete response + partial response and assessed by Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Will be calculated as the percent of evaluable patients who are responders, and confidence intervals will be constructed using the Wilson score interval method.

    From enrollment to the end of treatment, up to 2 years

Secondary Outcomes (2)

  • Progression-free Survival (PFS)

    Up to 6 months from study entry

  • Percentage of Patients Experiencing Grade 3 or 4 Adverse Events

    From initiation of treatment to disease progression, disease recurrence, or death from any cause assessed up to 2 years

Other Outcomes (2)

  • Biomarker Predictors of Response to Tazemetostat

    Up to 2 years

  • Change in Tumor Genomics

    Up to 2 years

Study Arms (1)

Treatment (tazemetostat)

EXPERIMENTAL

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

Drug: Tazemetostat

Interventions

Given PO

Also known as: E 7438, E-7438, E7438, EPZ 6438, EPZ-6438, EPZ6438
Treatment (tazemetostat)

Eligibility Criteria

Age12 Months - 21 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Patient must have enrolled onto APEC1621SC and must have been given a treatment assignment to Molecular Analysis for Therapy Choice (MATCH) to APEC1621C based on the presence of an actionable mutation
  • Patients must have radiographically measurable disease at the time of study enrollment; patients with neuroblastoma who do not have measurable disease but have MIBG+ evaluable disease are eligible; measurable disease in patients with CNS involvement is defined as tumor that is measurable in two perpendicular diameters on magnetic resonance imaging (MRI) and visible on more than one slice; Note: The following do not qualify as measurable disease:
  • Malignant fluid collections (e.g., ascites, pleural effusions)
  • Bone marrow infiltration except that detected by MIBG scan for neuroblastoma
  • Lesions only detected by nuclear medicine studies (e.g., bone, gallium or positron emission tomography \[PET\] scans) except as noted for neuroblastoma
  • Elevated tumor markers in plasma or cerebrospinal fluid (CSF)
  • Previously radiated lesions that have not demonstrated clear progression post radiation
  • Leptomeningeal lesions that do not meet the measurement requirements for Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
  • Karnofsky \>= 50% for patients \> 16 years of age and Lansky \>= 50 for patients =\< 16 years of age; Note: Neurologic deficits in patients with CNS tumors must have been stable for at least 7 days prior to study enrollment; patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score
  • Patients must have fully recovered from the acute toxic effects of all prior anti-cancer therapy and must meet the following minimum duration from prior anti-cancer directed therapy prior to enrollment; if after the required timeframe, the numerical eligibility criteria are met, e.g. blood count criteria, the patient is considered to have recovered adequately
  • Cytotoxic chemotherapy or other anti-cancer agents known to be myelosuppressive
  • \>= 21 days after the last dose of cytotoxic or myelosuppressive chemotherapy (42 days if prior nitrosourea)
  • Anti-cancer agents not known to be myelosuppressive (e.g. not associated with reduced platelet or absolute neutrophil count \[ANC\] counts): \>= 7 days after the last dose of agent
  • Antibodies: \>= 21 days must have elapsed from infusion of last dose of antibody, and toxicity related to prior antibody therapy must be recovered to grade =\< 1
  • Corticosteroids: If used to modify immune adverse events related to prior therapy, \>= 14 days must have elapsed since last dose of corticosteroid
  • +30 more criteria

You may not qualify if:

  • Pregnant or breast-feeding women will not be entered on this study because there is currently no available information regarding human fetal or teratogenic toxicities; pregnancy tests must be obtained in girls who are post-menarchal; males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method for the duration of study treatment; female subjects of childbearing potential should agree to remain abstinent or use adequate contraceptive methods for 30 days after the last dose of tazemetostat; male subjects should agree to remain abstinent or use adequate contraceptive methods, and agree to refrain from donating sperm, and for 90 days after the last dose of tazemetostat
  • Patients receiving corticosteroids who have not been on a stable or decreasing dose of corticosteroid for at least 7 days prior to enrollment are not eligible; if used to modify immune adverse events related to prior therapy, \>= 14 days must have elapsed since last dose of corticosteroid
  • Patients who are currently receiving another investigational drug are not eligible
  • Patients who are currently receiving other anti-cancer agents are not eligible
  • Patients who are receiving cyclosporine, tacrolimus or other agents to prevent graft-versus-host disease post bone marrow transplant are not eligible for this trial
  • Patients who are currently receiving drugs that are strong inducers or strong inhibitors of CYP3A4 are not eligible; strong inducers or inhibitors of CYP3A4 are prohibited from 14 days prior to the first dose of tazemetostat to the end of the study; Note: Dexamethasone for CNS tumors or metastases, on a stable dose, is allowed
  • Patients who have an uncontrolled infection are not eligible
  • On complete blood count (CBC) differential, patients must not have any significant morphologic abnormalities concerning for myeloproliferative neoplasm (MPN)/myelodysplastic syndrome (MDS) or T- acute lymphoblastic leukemia (ALL)
  • Patients must not have thrombocytopenia, neutropenia, or anemia of grade \>= 3 (per CTCAE 5.0 criteria) or any prior history of myeloid malignancies, including myelodysplastic syndrome (MDS)
  • Patients with a history of prior history of T-lymphoblastic lymphoma (LBL)/T-ALL
  • Patients with any prior history of myeloid malignancies, including myelodysplastic syndrome (MDS).
  • Patients who have received prior solid organ transplantation are not eligible
  • Patients who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study are not eligible
