Brief Summary

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.

Conditions

Unspecified Adult Solid Tumor

Keywords

refractory; prior treatment; solid tumors; phase I; phase 1

Outcome Measures

Primary Outcomes (1)

• Maximum tolerated dose of imatinib when given together with bevacizumab and metronomic cyclophosphamide

  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.

Secondary Outcomes (2)

• Pharmacokinetics of imatinib

  After the last patient completes PKs on Cycle 1 Day 16

• Safety of imatinib in combination with cyclophosphamide and bevacizumab

  After all patients have completed study therapy. Safety data will be monitored throughout the study.
