Phase 1TerminatedNCT01258634

University of Chicago2 enrolled

Overview

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.
