Brief summary:
This phase I/randomized phase II trial is studying the side effects and best dose of bevacizumab and to see how well it works when given together with or without MEDI-522 in treating patients with unresectable or metastatic kidney cancer. Monoclonal antibodies, such as bevacizumab and MEDI-522, 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. Bevacizumab and MEDI-522 may also stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether bevacizumab is more effective when given together with or without MEDI-522 in treating kidney cancer.

Detailed description:
PRIMARY OBJECTIVES:

I. To assess the appropriate dose of bevacizumab when administered with humanized monoclonal antibody MEDI-522 in patients with unresectable or metastatic renal cell carcinoma previously treated with sunitinib malate or sorafenib tosylate. (Phase I) II. To compare the progression-free survival of these patients treated with bevacizumab with versus without humanized monoclonal antibody MEDI-522. (Phase II) III. To evaluate the qualitative and quantitative toxicities of bevacizumab and humanized monoclonal antibody MEDI-522 in these patients. (Phase II) IV. To estimate overall survival and RECIST response rate (i.e., confirmed and unconfirmed, complete and partial responses) in both treatment arms. (Phase II)

OUTLINE: This is a multicenter, phase I, dose-escalation study of bevacizumab followed by a randomized phase II study.

PHASE I: Patients receive bevacizumab IV over 30-90 minutes on days 1 and 15 and humanized monoclonal antibody MEDI-522 IV on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity until the recommended phase II dose (RPTD) of bevacizumab is determined.

PHASE II: Patients are stratified according to the number of prior treatment regimens for renal cell carcinoma (1 vs 2) and whether there is a clear cell component (yes vs no). Patients are randomized to 1 of 2 treatment arms:

ARM I: Patients receive bevacizumab (10 mg/kg) IV over 30-90 minutes on days 1 and 15.

ARM II: Patients receive bevacizumab IV as in arm I at the RPTD determined in phase I, and humanized monoclonal antibody MEDI-522 (8 mg/kg) IV over 30 minutes on days 1, 8, 15, and 22.

In both arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed periodically for up to 3 years.

Arms: arm 1: Patients receive bevacizumab (10mg/kg) IV over 30-90 minutes on days 1 and 15. arm 2: Patients receive bevacizumab IV as in arm I at the RPTD determined in phase I, and humanized monoclonal antibody MEDI-522 (8mg/kg) IV over 30 minutes on days 1, 8, 15, and 22.
