Active clinical trials for "Sarcoma, Ewing"

This phase II trial study has a 6-patient feasibility portion studying the tolerability of chemotherapy with vincristine sulfate together with topotecan hydrochloride, cyclophosphamide, and bevacizumab in treating young patients with refractory or first recurrent extracranial Ewing's sarcoma. If the therapy is considered tolerable, this feasibility run-in will be followed by a randomized phase II portion studying giving vincristine sulfate together with topotecan hydrochloride, and cyclophosphamide to see how well it works compared with giving vincristine sulfate together with topotecan hydrochloride, cyclophosphamide, and bevacizumab in treating young patients with refractory or first recurrent extracranial Ewing's sarcoma. Drugs used in chemotherapy, such as vincristine sulfate, topotecan hydrochloride, and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop tumor growth by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab may kill more tumor cells.

This is a phase 1 study of anti-IGF-IR CP-751,871 in patients with solid tumors currently enrolling patients 9 years old and older with Ewing's sarcoma family of tumors (Ewing's, PNET and Askin's).

This phase I trial is studying the side effects of fluorine F18 EF5 when given during positron emission tomography to find oxygen in tumor cells of patients who are undergoing surgery or biopsy for newly diagnosed brain tumors. Diagnostic procedures using fluorine F 18 EF5 and positron emission tomography to detect tumor hypoxia may help in planning cancer treatment

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. PURPOSE: This phase II trial is studying how well imatinib mesylate works in treating patients with recurrent Ewing's family of tumors or desmoplastic small round-cell tumor.

Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have relapsed or refractory solid tumors of childhood. Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for their growth.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining chemotherapy with biological therapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy with or without biological therapy in treating patients who have newly diagnosed high-risk Ewing's sarcoma.

This is a single arm study. The tumor specimen is analyzed for the presence of a fusion protein which corresponds to available peptides. Patients undergo T cell harvest 10 days after an initial priming peptide-pulsed antigen presenting cell (APC) vaccine is performed. Fresh APCs are utilized for initial priming vaccination. All subsequent vaccinations will use cryopreserved APCs. Minimum number of APCs administered per vaccination is 100,000/kg and maximum is 100,000,000/kg. Patients undergo cytoreductive therapy for the treatment of their particular malignancy. This therapy usually consists of multiagent chemotherapy in the context of a separate protocol. Following chemotherapy, infusion of harvested T cells followed by infusion of peptide-pulsed APC vaccinations occurs every 6 weeks for a total of 3 post-priming vaccinations. Influenza vaccine is administered by intramuscular injection concurrent to peptide-pulsed APC vaccines. Interleukin -2 (IL-2) is administered as a continuous intravenous (IV) infusion for 4 days/week for 3 successive weeks starting on the same day as T cell /peptide-pulsed infusions.

The purpose of this study is to find the number of natural killer (NK) cells from non-HLA matched donors that can be safely infused into patients with cancer. NK cells are a form of lymphocytes that defend against cancer cells. NK cells in cancer patients do not work well to fight cancer. In this study, the NK cells are being donated by healthy individuals without cancer who are not "matched" by human leukocyte antigen (HLA) genes to patients. After receiving these NK cells, patients may also be given a drug called ALT803. ALT803 is a protein that keeps NK cells alive, helps them grow in number and supports their cancer-fighting characteristics. HLA-unmatched NK cell infusion is investigational (experimental) because the process has not approved by the Food and Drug Administration (FDA).

This is a Phase I trial with new experimental drugs such as simvastatin in combination with topotecan and cyclophosphamide in the hopes of finding a drug that may work against tumors that have come back or that have not responded to standard therapy. This study will define toxicity of high dose simvastatin in combination with topotecan and cyclophosphamide and evaluate for cholesterol levels and IL6/STAT3 pathway changes as biomarkers of patient response.

Tumors of the Ewing sarcoma family (ES) affect children, adolescents and young adults. The reported incidence is 0.6 cases per million inhabitants every year. The peak incidence occurs between 10 and 20 years and it is rarely diagnosed beyond 30. The ES is a severe disease with a progression-free survival after 5 years of 60% in cases without metastasis and deadly in the majority of patients presenting metastasis. The ES is considered a systemic disease because, despite receiving an adequate local treatment, over 90% of patients deaths occur due to disseminated disease. Combined therapy of surgery, radiotherapy and chemotherapy has led to an improvement in the prognosis, achieving a survival of about 60% in most series The MSKCC P6 protocol was developed for the treatment of high risk ES. In 2003, Kolb et al. reported the MSKCC experience after a 4-years follow-up of 68 patients who had been included from 1990 to 2001. Following the MSKCC P6 protocol, a survival rate of 82% was achieved in patients without metastasis, superior to the achieved with less intensive protocols. Following the guidelines of the MSKCC P6 protocol, in 2002 we modified the treatment schedule to create the modified P6 protocol (MP6). GEIS intends to develop MP6 as a clinical trial, which could provide the following potential advantages about current treatments: Lower total dose of alkylating agents. Early cardioprotection with dexrazoxane. Radiotherapy adjusted to the initial response. Pilot trial with the combination of Gemcitabine + Docetaxel for high-risk patients.
