2 Clinical Trials for Various Conditions
Background: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood. Two types are embryonal RMS (ERMS) and alveolar RMS (ARMS). Dasatinib may block over-expression of a certain enzyme. Ganitumab may block a certain growth factor, which might suppress tumor growth. This drug combination may help slow tumor growth in people with ERMS and ARMS. Objective: To see if dasatinib combined with ganitumab is safe and shrinks or slows the growth of tumors in people with ERMS and ARMS. Eligibility: People any age who have ERMS or ARMS that did not respond to previous treatment and who can swallow tablets Design: Participants will be screened with: * Medical history * Physical exam * Blood, urine, and heart tests * Scans/x-rays * Tissue sample: This can be from previous surgery or biopsy. * Optional biopsy: A small piece of the tumor is removed with a needle. Participants will be asked to co-enroll in another protocol. Participants will get a drug interaction handout and wallet card that show what foods and medications to avoid. Participants will be treated in cycles. The first cycle is 35 days, and the rest are 28 days. Participants will take dasatinib by mouth daily. They will get ganitumab through an intravenous (IV) every 2 weeks. They will have a physical exam every 1-2 weeks, and urine and heart tests before most cycles. Participants will continue treatment as long as they do not have severe side effects, or their tumors do not get worse. After ending treatment, participants will have a visit. This includes repeats of the screening tests.
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.
