The purpose of this study is to assess whether preoperative chemotherapy, as an adjunct to curative-intent surgery, improves the prognosis of high risk DDLPS (dedifferentiated Liposarcoma) and LMS (Leiomyosarcoma) patients as measured by disease free survival. After confirmation of eligibility criteria, patients will be randomized to either the standard arm or experimental arm.

The purpose of this study is to compare the objective response rate (ORR) by IRR of ripretinib vs sunitinib using modified Response Evaluation Criteria in Solid Tumors v1.1 – GIST-specific (mRECIST). Also, to compare the overall survival (OS) of ripretinib vs sunitinib.

The primary objectives of this study are to examine the correlation of change in ctDNA with objective tumor response per Response Evaluation Criteria in Solid Tumors (RECIST), and to examine the correlation of change in ctDNA with progression free survival (PFS).

The purpose of this study is to determine the feasibility of ctDNA detection in patients with advanced translocation-associated sarcomas.

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 purposes of this study are to characterize the long-term risk of hepatic failure with TURALIO™, and to evaluate the mechanism of liver injury based upon liver biopsy information.

The purpose of this study is to evaluate olaparib and temozolomide in treating patients with uterine leiomyosarcoma (LMS) that has spread to other places of the body or cannot be removed by surgery. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, 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 olaparib and temozolomide may work better than giving either drug alone in treating patients with LMS.

The primary objectives of this study are to examine the correlation of change in ctDNA with objective tumor response per Response Evaluation Criteria in Solid Tumors (RECIST), and to examine the correlation of change in ctDNA with progression free survival (PFS).

The purpose of this study is to evaluate the association between tumor characteristics assessed by contrast-enhanced MRI and location with presence of circulating tumor DNA (ctDNA) in patients with localized, high-grade leiomyosarcoma [Time Frame: 2 years ].

The purpose of this study is to evaluate how well trametinib works in treating patients with epithelioid hemangioendothelioma that has spread to other places in the body, nearby tissue or lymph nodes, or cannot be removed by surgery. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

The purpose of this study is to determine the tolerability of lurbinectedin with doxorubicin in people with soft tissue sarcoma, and  to determine which is more effective at treating leiomyosarcoma, lurbinectedin with doxorubicin or lurbinectedin alone.

The purpose of this study is to assess how well belinostat and SGI-110 (guadecitabine) or ASTX727 work in treating patients with conventional chondrosarcoma that cannot be removed by surgery (unresectable) and has spread to other places in the body (metastatic). Belinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as guadecitabine, 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 belinostat and guadecitabine may lower the chance of chondrosarcoma growing or spreading.

The purpose of this study is to compare the effectiveness of DCC-2618 to sunitinib in GIST patients who progressed on or were intolerant to first-line anticancer treatment with imatinib. Approximately 358 patients will be randomized in a 1:1 ratio to DCC-2618 150 mg once daily (QD) (continuous dosing for 6 week cycles) or sunitinib 50 mg QD (6 week cycles, 4 weeks on, 2 weeks off).

The purpose of this study is to compare the effect of the combination of olaparib and temozolomide to the usual treatment (trabectedin and pazopanib) for uterine leiomyosarcoma that has spread to other places in the body (advanced) after initial chemotherapy has stopped working. 

The NIR-DT-301 Phase 3, double-blind, placebo-controlled study is being conducted to determine the efficacy, safety, and tolerability of nirogacestat in participants with progressing desmoid tumors.

The purpose of this study is to evaluate the safety and effectiveness of AL3818 (catequentibub, anlotinib) hydrochloride in the treatment of metastatic or advanced alveolar soft part sarcoma (ASPS), leiomyosarcoma (LMS), and synovial sarcoma (SS). All participants with ASPS will receive open-label AL3818. In participants with LMS or SS, AL3818 will be compared to IV dacarbazine. Two-thirds of the participants will receive AL3818, one-third of the participants will receive IV dacarbazine.

The purpose of this research is to determine whether circulating tumor DNA, RNA or proteins can be detected in the blood of patients with sarcoma. We are also interested in learning if these levels change over time while receiving chemotherapy. Patients with advanced sarcoma who will receive chemotherapy will be asked to participate. Study participation involves blood-draws of approximately 4 tablespoons of blood at each of 4 separate time-points as well as access to archived tumor tissue, or fresh tumor tissue at the time of clinically indicated biopsy or surgery.  We hypothesize that circulating tumor DNA, RNA and/or proteins will be detectable in blood of sarcoma patients, and change in measured values over time will correlate with disease response or progression on therapy.

Pediatric patients weighing at least 10 kg will be considered for enrollment. For pediatric participants, 1.5 tablespoons of blood at each of 4 separate time-points will be collected. All blood collection will coincide with clinical lab draws. 

The purpose of this study is to provide patients who have locally advanced unresectable or metastatic gastrointestinal stromal tumor (GIST) and have received treatment with at least 2 prior Food and Drug Administration (FDA)-approved therapies early access to ripretinib until such time that ripretinib becomes commercially available or the Sponsor chooses to discontinue the program.

The purpose of this study is to evaluate how well trabectedin and olaparib work in treating patients with sarcoma that cannot be removed by surgery or has spread to other places in the body.

Drugs used in chemotherapy, such as trabectedin, work in different ways to stop the growth of tumor cells, either by killing cells, stopping them from dividing or stopping them from spreading. Olaparib may stop the growth of tumor cells by blocking pathways responsible for repairing damaged cells. Giving trabectedin and olaparib may shrink or stop the tumor from growing.
