简要总结
RATIONALE: Imatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Bevacizumab and cyclophosphamide may also stop the growth of tumor cells by blocking blood flow to the tumor. Imatinib and bevacizumab may help cyclophosphamide work better by making tumor cells more sensitive to the drug. Giving cyclophosphamide once a day together with imatinib and bevacizumab may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of imatinib when given together with bevacizumab and cyclophosphamide in treating patients with refractory metastatic solid tumors.
详细描述
OBJECTIVES:
Primary
- Determine the maximum tolerated dose of imatinib when given together with bevacizumab and metronomic cyclophosphamide in patients with refractory metastatic solid tumors.
- Determine the safety profile of this regimen in these patients.
Secondary
- Determine the effects of cyclophosphamide and bevacizumab on imatinib pharmacokinetics.
- Determine if patients treated with this regimen achieve plasma levels of cyclophosphamide that are predicted to be antiangiogenic.
- Determine the effects of this regimen on the number of circulating endothelial cells, endothelial progenitor cells, activated endothelial cells, and circulating tumor cells.
- Determine the effects of this regimen on parameters measured by CT scan perfusion (e.g., regional blood flow, blood volume, permeability-surface area product, and mean transit time).

结局指标
主要结局
Maximum tolerated dose of imatinib when given together with bevacizumab and metronomic cyclophosphamide
时间窗: Safety data will be assessed after 3 patients and 6 patients complete 42 days of study treatment to determine whether to dose escalate to the next cohort.
次要结局
- Safety of imatinib in combination with cyclophosphamide and bevacizumab(After all patients have completed study therapy. Safety data will be monitored throughout the study.)
- Pharmacokinetics of imatinib(After the last patient completes PKs on Cycle 1 Day 16)
