Bevacizumab, Sorafenib, and Temsirolimus in Treating Patients With Metastatic Kidney Cancer
This study is currently recruiting participants.

ClinicalTrials.gov Identifier: NCT00378703
  Purpose

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. Bevacizumab and sorafenib may stop the growth of tumor cells by blocking blood flow to the tumor. Temsirolimus and sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving different combinations of bevacizumab, sorfenib, and temsirolimus may be more effective than bevacizumab alone in treating metastatic kidney cancer.

PURPOSE: This randomized phase II trial is studying different combinations of bevacizumab, temsirolimus, and sorafenib to see how well they work compared with bevacizumab alone in treating patients with metastatic kidney cancer.

Detailed Description:

OBJECTIVES:

Primary

  • Compare progression-free survival (PFS) of patients with advanced renal cell carcinoma treated with different combinations of bevacizumab, sorafenib tosylate, and temsirolimus vs bevacizumab alone.

Secondary

  • Assess the significance of changes in tumor size over early time points as a predictor of PFS of patients treated with these regimens.
  • Compare the number and percentage of patients with stable disease at 6 months of therapy (failure to progress).
  • Compare the safety of these regimens in these patients.
  • Compare overall survival of patients treated with these regimens.
  • Compare the objective response rate in patients treated with these regimens.
  • Assess pathology, angiogenesis histology, and activation status of MAP kinase and VEGFR2 pathways and relate to clinical outcome.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to prior cytokine or vaccine therapy (no vs yes) and Motzer risk category (low vs intermediate vs high). Patients are randomized to 1 of 4 treatment arms.

  • Arm A: Patients receive bevacizumab IV over 30-90 minutes on days 1 and 15.
  • Arm B: Patients receive temsirolimus IV over 30 minutes on days 1, 8, 15, and 22 and bevacizumab as in arm A.
  • Arm C: Patients receive bevacizumab as in arm A and oral sorafenib tosylate twice daily on days 1-28.
  • Arm D: Patients receive temsirolimus as in arm B and sorafenib tosylate as in arm C.

In all arms treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically for 5 years.

PROJECTED ACCRUAL: A total of 360 patients will be accrued for this study.
