Active clinical trials for "Sarcoma, Ewing"

This is a multi-site study with plerixafor in pediatric cancer patients. The study will be conducted in 2 stages: Stage 1 is a dose-escalation study. Stage 2 is an open-label, randomized, comparative study using the appropriate dosing regimen identified in the Stage 1 dose-escalation study. All participating patients will receive a standard mobilization regimen as per study site practice guidelines (either chemotherapy plus once daily granulocyte-colony stimulating factor (G-CSF) or once daily G-CSF alone). The only change to the standard mobilization regimen is the addition of plerixafor treatment prior to apheresis for all patients in Stage 1 (dose escalation), and for those patients randomized to the plerixafor plus standard mobilization treatment arm in Stage 2 (randomized, comparative). Stage 1 will enroll at least 27 patients. Stage 2 will enroll at least 40 patients.

This study will be carried out in children with diagnosis of cancer with tumors known to express N-glycolylated gangliosides. The disease must be resistant to conventional therapy. The acute toxicity and immune response will be evaluated. The expression of N-glycolylated gangliosides in tumors has previously been investigated in the tumor sample bank at this Hospital. The expression of N-glycolyl GM3 was shown in neuroblastoma, Ewing's sarcoma, Wilm's tumor and retinoblastoma. Gliomas and the aforementioned tumor types have a very bad prognosis when conventional treatment is ineffective. New therapeutic strategies have thus been examined, and several immunotherapeutic approaches, including dendritic cell vaccines, peptide vaccines and anti-idiotype vaccines are currently being assessed. Racotumomab is an anti-idiotype antibody capable of inducing anti-N-glycolyl GM3 antibodies in patients with melanoma, breast cancer and lung cancer. Dose escalation studies have shown the safety of racotumomab in the 0.5 to 2 mg dose range. The 1 mg dose level was selected for the ensuing clinical studies. This clinical trial in children involves three dose levels: 0.15 mg, 0.25 mg and 0.4 mg, owing to the difference in body surface between an adult (1.73 sq. m in average) and the candidate population for this study (0.55 to 0.7 sq. m).

The objective of these studies is to use changes in 3 Tesla MRI measurements of tumor protein content, cell density, and microvessel perfusion, obtained before and after a single cycle of NAC, to predict eventual tumor response observed at the conclusion of NAC, within patients with osteosarcoma or Ewing Sarcoma.

This phase I/II trial studies the side effects and best dose of talazoparib and temozolomide and to see how well they work in treating younger patients with tumors that have not responded to previous treatment (refractory) or have come back (recurrent). Talazoparib may stop the growth of cancer 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 cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving talazoparib together with temozolomide may work better in treating younger patients with refractory or recurrent malignancies.

This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and to see how well they work in treating patients with advanced or metastatic sarcoma. Vismodegib may slow the growth of tumor cells. Gamma-secretase/notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vismodegib together with gamma-secretase/notch signalling pathway inhibitor RO4929097 may be an effective treatment for sarcoma.

This phase II trial is studying the side effects of and how well alisertib works in treating young patients with relapsed or refractory solid tumors or leukemia. Alisertib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This is a phase II Multicenter, Open-label, Clinical and Pharmacokinetic Study of Zalypsis® (PM00104) in Patients with Unresectable Locally Advanced and/or Metastatic Ewing Family of Tumors (EFT) Progressing After at Least One Prior Line of Chemotherapy to determine the antitumor activity of Zalypsis.

This randomized phase II trial studies how well giving temozolomide and irinotecan hydrochloride together with or without bevacizumab works in treating young patients with recurrent or refractory medulloblastoma or central nervous system (CNS) primitive neuroectodermal tumors. Drugs used in chemotherapy, such as temozolomide and irinotecan 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. 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. It is not yet known whether temozolomide and irinotecan hydrochloride are more effective with or without bevacizumab in treating medulloblastoma or CNS primitive neuroectodermal tumors.

Ewing Sarcoma Primary objectives: Standard Risk R1: in a randomised trial, to examine whether add-on treatment with zoledronic acid in addition to induction and maintenance chemotherapy improves event-free survival in patients with localised Ewing sarcoma and good histological response or with initial tumour volume <200 mL compared to no add-on treatment. *High Risk R2: in a randomised trial, to examine whether high-dose chemotherapy using busulfan-melphalan with autologous stem cell reinfusion, compared with standard chemotherapy, improves event-free survival in patients with localised Ewing sarcoma and poor histological response or tumour volume ≥200 mL (R2loc). In patients with pulmonary metastases high dose busulfan-melphalan chemotherapy with autologous stem cell reinfusion is randomised versus standard chemotherapy plus whole lung irradiation (R2pulm). Very High Risk R3: in a randomised trial, to examine whether the addition of high dose chemotherapy using treosulfan-melphalan followed by autologous stem cell reinfusion to eight cycles of standard adjuvant chemotherapy, compared to eight cycles of standard adjuvant chemotherapy alone, improves event-free survival in patients with primary disseminated disease. *R2 accrual discontinued on December 1st 2015.

Background: Pediatric solid tumors (Ewing's sarcoma, rhabdomyosarcoma, and neuroblastoma) are often difficult to cure with standard treatment. Immune therapy using an experimental vaccine made from proteins from the patient's tumor cells may boost the body's immune response against the tumor. The effects of chemotherapy on the immune system can potentially make immunotherapy more effective if administered soon after completion of chemotherapy. The addition of recombinant human IL-7 (interleukin 7) (rhIL-7 (recombinant human interleukin 7)) may make the immunotherapy more effective. Objectives: -To determine whether immune therapy given after immune suppression can help the body fight the tumor and to determine the safety of the treatment. Eligibility: -Patients with solid tumors, i.e., Ewing's sarcoma, rhabdomyosarcoma or neuroblastoma whose disease has recurred after treatment or spread beyond the original site Design: Patients undergo tumor biopsy (removal of a piece of tumor tissue) to collect tumor cells for making a vaccine from proteins in the patient's tumor and apheresis (removal of a quantity of white blood cells) to collect white cells for re-building the immune system after immune therapy. Apheresis is repeated three times during immunotherapy (weeks 8, 14 and 20). After receiving standard chemotherapy for their tumor (and an additional course of fludarabine and cyclophosphamide to further suppress immunity if needed) patients receive immune therapy in Cohorts A and B. rhIL-7 is given 48 hours before the vaccine, as an injection under the skin in an extremity that will not be used for the vaccine in patients in Cohort B only. You will be watched closely for 6 hours after the rhIL-7 for any signs of reaction. rhIL-7 will be given before vaccine doses #1, #2, #3, and #4. The vaccine is given at study weeks 2, 4, 6, 8, 10 and 12. Each vaccine is given as a total of six separate rhIL-7 followed by injections: three intradermal (like a (tuberculosis) TB test) on one arm or leg and three subcutaneous (like those for insulin injections for diabetes). on the other arm or leg. An anesthetic cream may be used to minimize the discomfort of injections. Patients' white cells are returned to them by infusion through a vein on the first day of immune therapy. Imaging studies and immune studies are done at weeks 1, 8 and 20 to determine the response to treatment on the tumor and on the immune system.
