Malignant Rhabdoid Tumor clinical trials at UCSF
2 in progress, 2 open to new patients

  • A Phase 1 Study of the EZH2 Inhibitor Tazemetostat in Pediatric Subjects With Relapsed or Refractory INI1-Negative Tumors or Synovial Sarcoma

    open to eligible people ages 6 months to 21 years

    This is a Phase I, open-label, dose escalation and dose expansion study with a BID oral dose of tazemetostat. Subjects will be screened for eligibility within 14 days of the planned first dose of tazemetostat. A treatment cycle will be 28 days. Response assessment will be evaluated after 8 weeks of treatment and subsequently every 8 weeks while on study. The study has two parts: Dose Escalation and Dose Expansion. Dose escalation for subjects with the following relapsed/refractory malignancies: - Rhabdoid tumors: - Atypical teratoid rhabdoid tumor (ATRT) - Malignant rhabdoid tumor (MRT) - Rhabdoid tumor of kidney (RTK) - Selected tumors with rhabdoid features - INI1-negative tumors: - Epithelioid sarcoma - Epithelioid malignant peripheral nerve sheath tumor - Extraskeletal myxoid chondrosarcoma - Myoepithelial carcinoma - Renal medullary carcinoma - Other INI1-negative malignant tumors (e.g., dedifferentiated chordoma) (with Sponsor approval) - Synovial Sarcoma with a SS18-SSX rearrangement Dose Expansion at the MTD or the RP2D - Cohort 1 - ATRT - Cohort 2 - MRT/RTK/selected tumors with rhabdoid features - Cohort 3 - INI-negative tumors: - Epithelioid sarcoma - Epithelioid malignant peripheral nerve sheath tumor - Extraskeletal myxoid chondrosarcoma - Myoepithelial carcinoma - Renal medullary carcinoma - Chordoma (poorly differentiated or de-differentiated) - Other INI1-negative malignant tumors (e.g., dedifferentiated chordoma) with Sponsor approval - Cohort 4 - Tumor types eligible for Cohorts 1 through 3 or synovial sarcoma with SS18-SSX rearrangement

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

    open to eligible people ages 16 years and up

    This is a Phase II, multicenter, open-label, single arm, 2-stage study of tazemetostat 800 mg BID administered orally in continuous 28 day cycles. Screening of subjects to determine eligibility for the study will be performed within 21 days of the first planned dose of tazemetostat. Eligible subjects will be enrolled into one of fivecohorts based on tumor type: - Cohort 1: MRT, RTK, ATRT, or 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: Relapsed or refractory synovial sarcoma with SS18-SSX rearrangement - Cohort 3: 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: Renal medullary carcinoma (RMC) - Cohort 5: Epithelioid sarcoma (ES) Treatment with tazemetostat will continue until disease progression, unacceptable toxicity or withdrawal of consent, or termination of the study. Response assessment will be evaluated after 8 weeks of treatment and then every 8 weeks thereafter while on study.
