Purpose:

Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies such as trastuzumab can locate tumor cells and kill them without harming normal cells. Combining monoclonal antibody therapy with chemotherapy may kill more tumor cells. Phase II trial to study the effectiveness of chemotherapy with or without trastuzumab in treating patients who have metastatic osteosarcoma


Study summary:

PRIMARY OBJECTIVES: I. Determine the feasibility and safety of trastuzumab (Herceptin) and chemotherapy in patients with HER2-overexpressing (2+ level of expression) metastatic osteosarcoma. II. Determine the response rate and 3-year event-free survival of patients treated with this regimen. III. Determine the cardiac toxicity and late effects of this regimen in these patients. IV. Determine the response rate and 3-year event-free survival of poor-risk patients with HER2-negative tumors treated with chemotherapy without the addition of trastuzumab. OUTLINE: This is a multicenter study. Patients are stratified according to tumor HER2 status (positive vs negative). Patients receive induction therapy comprising doxorubicin IV over 20 minutes followed by cisplatin IV over 4 hours on days 1 and 2 of weeks 1 and 6, and methotrexate IV over 4 hours on day 1 of weeks 4, 5, 9, and 10. Patients also receive leucovorin calcium IV or orally every 6 hours beginning 24 hours after each methotrexate dose and continuing for at least 10 doses until methotrexate levels sufficiently decrease. Within 24-36 hours after completion of induction therapy, patients receive filgrastim (G-CSF) daily until blood counts recover. Patients undergo resection of any remaining primary tumor and/or metastatic lesions during week 11. Patients who are unable to undergo resection receive radiotherapy between weeks 11 and 17. Patients receive post-induction therapy comprising doxorubicin IV over 20 minutes on days 1 and 2 of weeks 17, 25, and 29; cisplatin IV over 4 hours on days 1 and 2 of weeks 17 and 25; methotrexate IV over 4 hours on day 1 of weeks 16, 20, 24, 28, 32, and 33; etoposide IV over 1 hour on days 1-5 of weeks 13, 21, and 34; and ifosfamide IV over 4 hours on days 1-5 of weeks 13, 21, 29, and 34. Patients also receive leucovorin calcium and G-CSF as in induction therapy. Patients whose tumors are found to over express HER2 (2+ level of expression) also receive trastuzumab IV over 30-90 minutes once a week for a total of 34 weeks in addition to the chemotherapy regimen. Patients are followed monthly for 1 year, every 2 months for 1 year, every 6 months for 2 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 80 patients (40 patients per stratum) will be accrued for this study within 2.5 years.
