Malignant Rhabdoid Tumor clinical trials at UC Cancer
2 research studies open to eligible people
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 17 years
This is a Phase I, open-label, dose escalation and dose expansion study with BID (suspension) and TID (tablet) 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 Escalation cohorts are closed to enrollment. Dose Expansion at the MTD or the RP2D - Cohort 1 - ATRT (closed to enrollment) - Cohort 2 - MRT/RTK/selected tumors with rhabdoid features (closed to enrollment) - 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 (closed to enrollment)
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 18 years and up
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.
