Temozolomide, Cixutumumab, and Combination Chemotherapy in Treating Patients With Metastatic Rhabdomyosarcoma

Location:

Rochester, MN

Trial status:

Open for Enrollment

Why is this study being done?

PRIMARY OBJECTIVES: I. To determine the feasibility of administering cixutumumab in combination with an intensive multi-agent interval compressed chemotherapy regimen for the treatment of high-risk metastatic rhabdomyosarcoma (RMS). II. To determine the feasibility of adding temozolomide to vincristine and irinotecan in these patients. III. To assess immediate and short-term side effects of concurrent temozolomide, vincristine, and irinotecan with radiotherapy in these patients. SECONDARY OBJECTIVES: I. To gain a preliminary estimate of the response rate to cixutumumab or temozolomide, vincristine, and irinotecan in these patients. II. To obtain preliminary efficacy data for cixutumumab or temozolomide in combination with an intensive multi-agent interval compressed chemotherapy regimen in these patients. III. To determine the effectiveness of detecting metastatic disease with fludeoxyglucose F 18 positron emission tomography (FDG PET) and to compare assessment of response using standard imaging techniques with response assessed by FDG PET. IV. To assess changes in serum levels of IGF-I, IGF-II, IGF-BP3 as biomarkers of IGF-IR inhibition. OUTLINE: This is a dose-escalation study of cixutumumab. Patients are assigned to 1 of 2 treatment groups according to the timing of their enrollment onto the study. GROUP 1: Patients receive vincristine sulfate IV on day 1 of weeks 1-5, 7, 8, 11, 12, 15, 16, 20-24, 28, 29, 32, 33, 35, 38, 41-44, 47, 48, 50, and 51; irinotecan hydrochloride IV over 90 minutes on days 1-5 of weeks 1, 4, 20, 23, 47, and 50; ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 of weeks 9, 13, 17, 26, and 30; doxorubicin hydrochloride IV on days 1 and 2 of weeks 7, 11, 15, 28, and 32; cyclophosphamide IV over 30-60 minutes on day 1 of weeks 7, 11, 15, 28, 32, 35, 38, 41, and 44; dactinomycin IV on day 1 of weeks 35, 38, 41, and 44; and cixutumumab IV over 1 hour on day 1 of weeks 1-51. Patients also undergo radiotherapy* on days 1-5 of weeks 20-24. GROUP 2: Patients receive vincristine sulfate, irinotecan hydrochloride, ifosfamide, etoposide, doxorubicin hydrochloride, cyclophosphamide, and dactinomycin and undergo radiotherapy* as in group 1. Patients also receive oral temozolomide on days 1-5 of weeks 1, 4, 20, 23, 47, and 50. GROUP 3: Patients receive vincristine sulfate, irinotecan hydrochloride, ifosfamide, etoposide, doxorubicin hydrochloride, cyclophosphamide, dactinomycin, and cixutumumab and undergo radiotherapy* as in group 1. Patients also receive temozolomide as in group 2. (Discontinued as of January 2013) NOTE: *Patients with parameningeal tumors and evidence of intracranial extension or those requiring emergency radiotherapy may receive radiotherapy starting in week 1; cixutumumab should be withheld during radiotherapy. After completion of study therapy, patients are followed up periodically for up to 10 years.
