Filter by:This is a pilot study that will allow investigators to collect data related to early and potentially more accurate response assessments using a chemotherapy protocol that eliminates methotrexate to maximize the dose intensity of doxorubicin. The pilot data will be used to seek funding to more fully address the hypotheses in a multi-institutional, Phase II or Phase III trial. The primary and secondary objectives are as follows: Primary: 1. To evaluate the feasibility and potential usefulness of measuring early changes in tumor metabolic activity, assessed by Fludeoxyglucose-Positron Emission Tomography (FDG-PET) imaging and alkaline phosphatase activity, as early predictors of histological response rate at 12 weeks in osteosarcoma patients. 2. To explore whether histological response can be assessed by a computer algorithm using virtual microscopic images of pathology material, and whether quantifying necrosis in this way correlates with microscope slide-based review. Secondary: 1. To gather pilot data on the histological response rate, 3-year event-free survival, and toxicity when children and young adults with resectable osteosarcoma are treated using a chemotherapy regimen of alternating courses of doxorubicin/cisplatin (DC) and doxorubicin/ifosfamide/etoposide (IDE). All patients will receive 4 courses of preoperative chemotherapy courses. With the exception of high-dose methotrexate, which is given weekly, preoperative and postoperative chemotherapy courses are planned to begin every 21 days. Patients with good histological response (those patients with > 90% tumor necrosis at time of definitive resection) will receive three postoperative chemotherapy courses. The 1st will consist of doxorubicin, dexrazoxane, cisplatin and Granulocyte-Colony Stimulating Factor (G-CSF)(or Polyethylene Glycol filgrastim). The 2nd course will consist of doxorubicin, dexrazoxane, ifosfamide, MESNA, etoposide, G-CSF (or PEG-filgrastim). The 3rd course will consist of ifosfamide, MESNA, etoposide, G-CSF (or PEG-filgrastrim). The total doxorubicin dose will be 450 mg/m2. Patients with poor response (those patients with < 90% tumor necrosis found on pathology at time of definitive resection) will receive five postoperative chemotherapy courses. High Dose-Methotrexate will be administered during the 1st and 3rd postoperative chemotherapy courses as 4-weekly and 2-weekly doses, respectively. The 2nd course will consist of doxorubicin, dexrazoxane, cisplatin and G-CSF (or PEG-filgrastim). The 4th course will consist of doxorubicin, dexrazoxane, ifosfamide, Mesna, etoposide, G-CSF (or PEG-filgrastim). The 5th cycle will consist of ifosfamide, Mesna, etoposide, G-CSF (or PEG-filgrastrim). The total doxorubicin dose will be 450 mg/m2.
This an an open-label study to define the safety profile and the maximum tolerated dose and confirm the clinical effective dose of palifosfamide-tris given intravenously in combination with etoposide and carboplatin in a wide range of cancers which etoposide and carboplatin are normally given. Once the maximum dose of palifosfamide-tris is determined,a Phase II study using the 3 agents combined will begin.
This treatment study for relapsed high-risk neuroblastoma, Ewings sarcoma, osteogenic sarcoma, rhabdomyosarcoma or synovial sarcoma involves an autologous cancer testis (CT) antigen specific dendritic cell (DC) vaccine preceded by decitabine as a demethylating chemotherapy.
Background: - The anti-cancer drug RO4929097 is being tested for its ability to block blood vessel growth to tumors and slow or stop the growth of cancer cells. However, it has been used in only a small number of adults and has not yet been tested in children. Researchers are interested in determining whether RO4929097 is a safe and effective treatment for tumors or leukemia that has not responded to standard treatment. Objectives: - To determine the safety and effectiveness of RO4929097 as a treatment for children and adolescents who have been diagnosed with certain kinds of cancer that have not responded to standard treatment. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid, nervous system, or blood-based cancers that have not responded to standard treatment. Design: - Participants will be screened with a medical history, physical examination, blood and urine tests, and imaging studies. Some participants may also have a bone marrow biopsy to evaluate the state of their disease. - Participants will be separated into three groups: One group will receive RO4929097 alone, and the other two will receive RO4929097 in combination with the immune-suppressing drug dexamethasone. - RO4929097 will be given as tablets on one of two schedules: days 1 to 3 of every week (Schedule A) or days 1 to 5 of every week (Schedule B). The dosing schedule will be determined randomly. Every 4-week treatment period is one cycle, and participants may receive RO4929097 for up to 24 cycles. - Participants will have frequent blood and urine tests and imaging studies to evaluate the progress of treatment, and will be asked to keep a diary to monitor any side effects.
The purpose of this study is to determine the Everolimus aim response in children and adolescents with refractory or relapsed osteosarcoma. The aim response is defined as complete or partial response (according to RECIST criteria) for at least 4 weeks, or stable disease for at least 12 weeks.
This study is an observational safety surveillance study designed to prospectively assess patients with high-grade osteosarcoma who are candidates for treatment with mifamurtide within the context of prevailing standard oncology practice
This research study is studying DNA biomarkers in tissue samples from patients with osteosarcoma. Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes the occur in DNA and identify biomarkers related to cancer. DNA analysis of tumor tissue may also help doctors predict how well patients will respond to treatment.
The primary purpose of this study is to determine the safety and feasibility of delivering HDMTX in an outpatient setting.
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 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.
