Clinical Trials Using Tazemetostat

Clinical trials are research studies that involve people. The clinical trials on this list are studying Tazemetostat. All trials on the list are supported by NCI.

NCI’s basic information about clinical trials explains the types and phases of trials and how they are carried out. Clinical trials look at new ways to prevent, detect, or treat disease. You may want to think about taking part in a clinical trial. Talk to your doctor for help in deciding if one is right for you.

Trials 1-10 of 10
  • Tazemetostat in Treating Patients with Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders with EZH2, SMARCB1, or SMARCA4 Gene Mutations (A Pediatric MATCH Treatment Trial)

    This phase II Pediatric MATCH trial studies how well tazemetostat works in treating patients with solid tumors, non-hodgkin lymphoma, or histiocytic disorders that have spread to other places in the body and have come back or do not respond to treatment and have EZH2, SMARCB1, or SMARCA4 gene mutations. Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

  • Tazemetostat and Pembrolizumab in Treating Patients with Locally Advanced or Metastatic Urothelial Carcinoma

    This phase I / II trial studies the side effects and best dose of tazemetostat and how well it works when given together with pembrolizumab in treating patients with urothelial carcinoma that has spread to nearby tissue or lymph nodes or other places in the body (locally advanced / metastatic). Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving tazemetostat and pembrolizumab may work better in treating patients with urothelial carcinoma compared to pembrolizumab without tazemetostat.

  • A Phase II, Multicenter Study of the EZH2 Inhibitor Tazemetostat in Adult Subjects With INI1-Negative Tumors or Relapsed / Refractory Synovial Sarcoma

    This is a Phase II, multicenter, open-label, single arm, 2-stage study of tazemetostat 800 mg BID (twice daily) and 1600 mg QD (once daily). Subjects will be screened for eligibility within 21 days of the planned date of the first dose of tazemetostat and enrolled into one of 8 cohorts: Cohort using tazemetostat 800 mg BID - Cohort 1 (Closed for enrollment): MRT, RTK, ATRT, and selected tumors with rhabdoid features, including small cell carcinoma of the ovary hypercalcemic type [SCCOHT], also known as malignant rhaboid tumor of the ovary [MRTO] - Cohort 2 (Closed for enrollment): Relapsed or refractory synovial sarcoma with SS18-SSX rearrangement - Cohort 3 (Closed for enrollment): Other INI1 negative tumors or any solid tumor with an EZH2 gain of function (GOF) mutation, including: epithelioid malignant peripheral nerve sheath tumor (EMPNST), extraskeletal myxoid chondrosarcoma (EMC), myoepithelial carcinoma, other INI1-negative malignant tumors with Sponsor approval (e.g., dedifferentiated chordoma) any solid tumor with an EZH2 GOF mutation including but not limited to Ewing's sarcoma and melanoma - Cohort 4 (Closed for enrollment): Renal medullary carcinoma (RMC) - Cohort 5 (Closed for enrollment): Epithelioid sarcoma (ES) - Cohort 6 (Opened for enrollment): Epithelioid sarcoma (ES) undergoing mandatory tumor biopsy - Cohort 7 (Opened for enrollment): Poorly differentiated chordoma (or other chordoma with Sponsor approval) Cohort using tazemetostat 1600 mg QD • Cohort 8 (Opened for enrollment): Epitheliod sarcoma Subjects will be dosed in continuous 28-day cycles. (Note: if treatment with study drug is discontinued prior to completing 2 years, subjects will be followed for a maximum duration of 2 years from start of study drug dosing.) Response assessment will be performed every 8 weeks while on study. Treatment with tazemetostat will continue until disease progression, unacceptable toxicity or withdrawal of consent, or termination of the study.

  • Tazemetostat in Combination With Doxorubicin as Frontline Therapy for Advanced Epithelioid Sarcoma

    This is a multicenter, double-blind, placebo-controlled, randomized phase 3 study with phase 1b portion designed to establish a recommended phase 3 dose (RP3D) and to evaluate the efficacy, PK, and safety of tazemetostat + doxorubicin vs placebo + doxorubicin in subjects with advanced epithelioid sarcoma (ES). This study will be conducted in 2 parts.

  • Tazemetostat Rollover Study (TRuST): An Open-Label Rollover Study

    This study will provide continuing availability to tazemetostat as a single agent to subjects who have completed their participation in an antecedent tazemetostat study (either with monotherapy or combination therapy). In addition, long-term safety and overall survival will be collected.

  • Study of Tazemetostat Together With Enzalutamide or With Abiraterone / Prednisone in Subjects With Castration Resistant Prostate Cancer That Has Spread Who Have Not Yet Received Chemotherapy

    This is a global, multi-center, open-label, randomized phase 1b, active-controlled safety and efficacy study of oral administration of tazemetostat in combination with enzalutamide or abiraterone / prednisone (phase 1b) versus enzalutamide or abiraterone / prednisone alone in asymptomatic or mildly symptomatic subjects with progressive, metastatic castration-resistant prostate cancer (mCRPC) who have progressed on either abiraterone acetate, enzalutamide, or apalutamide or who are second generation anti-androgen treatment naive, and who have not received chemotherapy for mCRPC. This study is designed to determine the recommended phase 2 doses (RP2D) of tazemetostat in combination with either enzalutamide or abiraterone / prednisone, based on safety, tolerability, pharmacokinetic, pharmacodynamic, and efficacy profiles.

  • Tazemetostat in Treating Patients with Recurrent Ovarian or Endometrial Cancer

    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.

  • Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients with Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphomas, or Histiocytic Disorders (The Pediatric MATCH Screening Trial)

    This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and / or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.
