Clinical Trials

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) - Cohort 6: Epithelioid sarcoma (ES) undergoing mandatory tumor biopsy - Cohort 7: Poorly differentiated chordoma (or other chordoma with Sponsor approval) 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.

The purpose of this study is to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma.

Additionally, to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

The purpose of this study is to evaluate the safety and effectiveness of milademetan compared to trabectedin in patients with unresectable (i.e., where resection is deemed to cause unacceptable morbidity or mortality) or metastatic DD liposarcoma that progressed on 1 or more prior systemic therapies, including at least 1 anthracycline-based therapy.

This phase III trial compares the effect of vinorelbine with vincristine, dactinomycin, and cyclophosphamide (VAC) followed by vinorelbine and cyclophosphamide versus VAC followed by vinorelbine and cyclophosphamide for the treatment of high risk rhabdomyosarcoma. Chemotherapy drugs, such as vinorelbine, vincristine, dactinomycin, and cyclophosphamide, 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. Giving vinorelbine and VAC may kill more tumor cells. Adding maintenance therapy (vinorelbine and cyclophosphamide) after VAC therapy, with or without vinorelbine, may help get rid of the cancer and/or lower the chance that the cancer comes back.

The purpose of this Phase 1/2 master protocol study is to evaluate if DCC-3009 is safe, tolerable and works effectively in the treatment of GIST. The study will use a modular approach with each module being defined according to therapy: DCC-3009 alone or DCC-3009 in combination with other anticancer therapies. Each module will be conducted in 2 parts: Part 1 (Dose Escalation) and Part 2 (Dose Expansion). Participants will be treated in 28-day treatment cycles with an estimated duration of up to 2 years.

Pazopanib is FDA approved as a second line and beyond treatment for metastatic soft tissue sarcoma. There is a population of elderly and debilitated soft tissue sarcoma patients that are not fit for standard first line chemotherapy that is doxorubicin based. As pazopanib is well tolerated with minimal side effects, the investigators propose a phase II study to evaluate pazopanib as a first-line agent in patients with non-resectable or metastatic disease who are not candidates for cytotoxic chemotherapy.

The purpose of this study is to evaluate whether the combination of lurbinectedin plus doxorubicin given as first line treatment for metastatic leiomyosarcoma (LMS) prolongs the progression-free survival (PFS) by Independent Review Committee (IRC) when compared to doxorubicin administered as a single agent.

The purpose of this study is to compare the effect of treatment with palbociclib alone to treatment with palbociclib plus cemiplimab for treating patients with dedifferentiated liposarcoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). 

This is a randomized, multicenter, double-blind, placebo-controlled, Phase 2-3 study of patients diagnosed with advanced unresectable dedifferentiated liposarcoma. Approximately 279 total patients will be randomized to study treatment (selinexor or placebo).

The purpose of this study is to evaluate abemaciclib versus placebo to treat Advanced Dedifferentiated Liposarcoma. Patients with progression of disease will cross over to open label abemaciclib.
