Summary

RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Zoledronic acid may stop the growth of tumor cells in bone. Giving bevacizumab together with cyclophosphamide and zoledronic acid may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects of giving bevacizumab together with cyclophosphamide and zoledronic acid in treating patients with recurrent or refractory high-risk neuroblastoma.

Detailed description

OBJECTIVES: Primary * To determine the toxicities and feasibility of bolus and metronomic cyclophosphamide when given in combination with zoledronic acid with and without bevacizumab in patients with recurrent or refractory high-risk neuroblastoma. Secondary * To preliminarily evaluate the antitumor activity of this regimen in these patients within the confines of a pilot study. OUTLINE: This is a multicenter study. Patients receive cyclophosphamide IV over 1 hour and zoledronic acid IV over 15 minutes on day 0 and oral cyclophosphamide once daily on days 1-27 in course 1. In course 2 and all subsequent courses, patients receive bevacizumab IV over 30-90 minutes on days 0 and 14, cyclophosphamide IV over 1 hour and zoledronic acid IV over 15 minutes on day 1, and oral cyclophosphamide once daily on days 0 and 2-27. Treatment repeats every 28 days for up to 2 years\* in the absence of disease progression or unacceptable toxicity. NOTE: \*Patients may receive up to 13 doses of zoledronic acid. After completion of study treatment, patients are followed periodically.

Conditions

• Neuroblastoma

Interventions

Type	Name	Description
DRUG	Bevacizumab	Every course will be 28 days. Bevacizumab 10 mg/kg/dose , will be administered intravenously every 14 days beginning on day 0 of the second course.
DRUG	cyclophosphamide	Cyclophosphamide will be administered as an intravenous (IV) bolus according to the protocol assigned dose level followed by daily oral dosing (25mg/m2/day) without interruption (unless toxicity supervenes).
DRUG	zoledronic acid	Administered on day 0 of course 1 and day 1 of course 2 and all subsequent courses in a dose of 4mg/m2 (max 4 mg per dose). On days when zoledronic acid (ZA) and cyclophosphamide (CTX) are given together, CTX should be given first.
