Active clinical trials for "Liposarcoma"

This is an open-label Phase 2 randomized study that will examine the use of the study agents, CMB305 (sequentially administered LV305 which is a dendritic cell-targeting viral vector expressing the New York Esophageal Squamous Cell Carcinoma 1 gene [NY-ESO-1] and G305 which is a NY-ESO-1 recombinant protein plus glucopyranosyl lipid adjuvant-stable emulsion [GLA-SE]) in combination with atezolizumab or atezolizumab alone, in participants with locally advanced, relapsed or metastatic sarcoma (synovial or myxoid/round cell liposarcoma) expressing the NY-ESO-1 protein. There is no formal primary hypothesis for this study.

The purpose of this study is to evaluate the effectiveness of a new investigational drug, ATX-101, for the treatment of dedifferentiated liposarcoma (LPS) and leiomyosarcoma (LMS). ATX-101 is an intravenous (IV) drug which blocks the interaction of a protein called PCNA with a number of "stress response" proteins. These interactions are thought to be important for cancer cell survival and growth. ATX-101 may disrupt these interactions and therefore help treat the cancer. In this study, all patients will receive the same treatment. Most of the exams, tests, and procedures are part of the usual approach to medical care for this condition. However, some additional tests or procedures may be performed, and other tests may be performed more frequently than usual.

Liposarcomas are soft tissue sarcomas most frequent. We distinguish three subtypes on the basis of their histological and cytogenetic characteristics: well-differentiated liposarcoma / dedifferentiated, myxoid liposarcoma and / or round cell liposarcoma and pleomorphic. Dedifferentiated liposarcomas (LDD) represent 20% of liposarcomas and are characterized by well-differentiated component associated with a contingent sarcomatous differentiation and fat-usually high grade. The LDD are most often rétropértionéal seat. Thus, their development is very long asymptomatic. At diagnosis, tumor volume is often very important making surgical removal impossible in a high proportion of cases. Operable tumors have also a risk of local recurrence by about 50% and about 20% metastatic. Chemotherapy is the only treatment of these advanced forms. However, the currently available drugs (adriamycin, ifosfamide) have only very limited effectiveness. Progression-free survival of patients does not exceed 2 months. The LDD is characterized cytogenetically by the constant presence of two amplicons (1p32 and 6q23) respectively targeting genes MAP3K5 and JUN. These two genes encode proteins involved in the signaling pathway Jun N-terminal kinase (JNK). Activation of JNK is involved in the loss of adipose differentiation and tumor aggressiveness of LDD. The plitidepsin is a drug capable of inducing apoptosis of tumor cells carrying a functional activation of the JNK pathway. This drug has such a pro-apoptotic and anti-proliferative in vitro models of LDD. plitidepsin could represent the treatment of choice for patients with advanced LDD. The objective of this study is to evaluate the anti-tumor activity of plitidepsin patients with locally advanced dedifferentiated liposarcomas and / or metastatic.

This phase Ib trial studies the side effects and best dose of ribociclib when giving together with doxorubicin hydrochloride in treating patients with soft tissue sarcomas that has spread to other places or that cannot be removed by surgery (advanced). Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as doxorubicin hydrochloride, 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 ribociclib and doxorubicin hydrochloride may work better in treating patients with soft tissue sarcoma.

This is a randomized, multicenter, double-blind, placebo-controlled, Phase 2-3 study of patients diagnosed with advanced unresectable dedifferentiated liposarcoma. Approximately 342 total patients will be randomized to study treatment (selinexor or placebo).

The eribulin, a microtubule-dynamics inhibitor was approved for specific subtypes of STS. Eribulin demonstrated significantly better OS compared to dacarbazine in previously treated patients with liposarcoma and leiomyosarcoma and approved as standard treatment. However, the median progression free survival (PFS) and response rate (RR) was similar for both groups which remains modest outcome of 2.6 months of PFS and 4% of RR. Therefore, to improve antitumor activity, further combination strategy is strongly warranted. Based on the previous studies, investigators suggest phase II trial of eribulin and gemcitabine combination in previously treated patients with unresectable, advanced, or metastatic leiomyosarcoma or liposarcoma.

Soft tissue sarcomas (STS) are a rare group of malignant heterogenous tumors (> 50 histological subtypes, including liposarcoma, the commonest subtype of STS) with distinct genetic, pathological and clinical profiles, and varying patterns of tumor spread. The optimal cytotoxic treatment for this group of patients remains uncertain. Single agents which are most effective include doxorubicin and ifosfamide, but objective response rates and progression-free survival times remain modest. There is clearly a need to improve treatment options for liposarcoma. Eribulin, a antimicrotubule agent that targets the protein tubulin in cells, interfering with cancer cell division and growth , has demonstrated activity in STS. Therefore, it is reasonable to explore whether other anti-microtubule agent like cabazitaxel have a role in STS. Cabazitaxel has been shown to be a relatively safe, effective and tolerated. This drug has been approved by FDA for prostate cancer. The main objective of this trial is to determine whether cabazitaxel demonstrate sufficient antitumor activity for liposarcoma.

L-sarcomas represent about one third of all adult soft tissue sarcomas (24 % liposarcomas and 12 % leiomyosarcomas). Approval for the induction of trabectedin into the treatment armamentarium of advanced and/or metastatic soft tissue sarcomas after treatment failure with anthracyclines and/or ifosfamide depended mainly on its activity in the L-sarcomas (Garcia-Carbonero 2004, Le Cesne 2005, and Demetri 2009). Significant activity has been described for the use of gemcitabine and especially the combination of gemcitabine and docetaxel mainly in leiomyosarcomas and liposarcomas (Maki 2007). However, the combination of gemcitabine and docetaxel is associated with significant toxicity. Pulmonary toxicity and refractory peripheral oedema are the most common severe adverse events. The aim of the present phase I study will be to examine safety data of this promising treatment combination of gemcitabine and trabectedin in L-sarcomas.

Retro peritoneal liposarcomas are rare (less than 15% of sarcomas) whose prognosis is locoregional. In the treatment of retroperitoneal liposarcomas main prognostic factor is the quality of the surgical resection. The effect of radiotherapy combined with surgery is uncertain and until now limited perhaps because of limited prescribed doses (of the order of 45Gy to 50Gy) due to high risk of organ toxicity nearby. The helical tomotherapy is an innovative equipment radiotherapy to make conformational radiotherapy modulation intensity and is particularly suitable for irradiations precision (imaging mode associated with daily scanner) in large complex volumes. Increasing doses (increase of the prescribed dose to 54 Gy, thus potentially curative), the helical tomotherapy should allow to improve the efficacy of radiotherapy.

The purpose of this study is to find out what effects, good and/or bad, Palbociclib (Ibrance) (formerly known as PD0332991) has on the patient and on the liposarcoma. Palbociclib is an investigational drug. An investigational drug is a medication that has not been approved for marketing by the Food and Drug Administration (FDA). Palbociclib blocks a protein called CDK4 which is part of a pathway in liposarcoma cells that is over-active. The investigators hope that blocking CDK4 will shut down this pathway in the liposarcoma cells and stop tumors from growing. Palbociclib is an oral medication.
