Filter by:The outcome of patients with metastatic Ewings Sarcoma is poor with current standard of care chemotherapy, with less than 30% survival. Based on recent encouraging pediatric literature we have designed this trial to improve the outcome of patients with metastatic Ewings sarcoma using Irinotecan and Temozolomide in addition to standard chemotherapy.
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 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 is a Phase 1/1B, non-randomized, open-label, dose-escalation study of robatumumab (SCH 717454, MK-7454) administered in combination with chemotherapy in pediatric participants with solid tumors, to be conducted in conformance with Good Clinical Practices. This study will evaluate the safety, tolerability and dose-finding of robatumumab when administered in combination with temozolomide and irinotecan (Arm A); or cyclophosphamide, doxorubicin, and vincristine (Arm B), or ifosfamide and etoposide (Arm C). The primary study hypothesis is that robatumumab can be safely administered in combination with chemotherapy regimens in pediatric participants with solid tumors.
The purpose of this study is to determine how long patients who undergo complete surgical removal of recurrent osteosarcoma in the lung will remain free of cancer after taking Saracatinib compared to patients taking placebo (a sugar pill).
The goal of this clinical research study is to learn if giving certain combinations of chemotherapy drugs before and after surgery, mostly in the outpatient clinic instead of in the hospital, can result in fewer hospital stays during treatment for osteosarcoma. The drugs and schedules will vary depending on the status of the cancer and its level of risk for spreading, but they will include combinations of doxorubicin (non-liposomal), cisplatin, methotrexate, and ifosfamide, as described below.
The purpose of this study is to demonstrate whether use of glucarpidase facilitates administration of the next cycle of chemotherapy as scheduled and improves safety and tolerability of HDMTX given with LV
Primary Objectives: 1. To evaluate the material properties, histomorphometric indices, bone mineral density (BMD), and presence of microfractures in retrieved large allograft cortical bone specimens removed from orthopaedic oncology patients. 2. To correlate physical properties to patient demographics and medical treatment received.
Participants with relapsed osteosarcoma that can be treated with surgery will be randomized to robatumumab administered intravenously (IV) at one of two dose levels. These participants will first receive robatumumab, have surgery performed, and continue to receive treatment every two weeks until a year of dosing, or until disease progression. Participants with unresectable osteosarcoma or Ewing Sarcoma will receive robatumumab IV once every two weeks until disease progression. Participants who achieve a complete response (CR) or partial response (PR) after tumor evaluations may undergo surgical resection. After surgery, participants are eligible to receive 10 mg/kg robatumumab until disease recurrence/progression or one year of total dosing, whichever occurs first.
Researchers have previously demonstrated loss of heterozygosity in a region on chromosome 18q, associated with osteogenic sarcomas in bone affected by Paget's disease. The loci used in this study are specifically described by those authors as showing loss of heterozygosity in 6 of 7 affected families.
