Phase II Open Label Trial of rIL-2 and Bevacizumab Combination in Patients With Metastatic Clear Cell Renal Carcinoma
Phase II Open Label Trial of rIL-2 and Bevacizumab Combination in Patients With Metastatic Clear Cell Renal Carcinoma
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 may also stop the growth of tumor cells by blocking blood flow to the tumor. Biological therapies, such as aldesleukin, may stimulate the immune system in different ways and stop tumor cells from growing. Giving bevacizumab together with aldesleukin may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving bevacizumab together with aldesleukin works in treating patients with metastatic clear cell carcinoma of the kidney.
OBJECTIVES:
Primary
Secondary
OUTLINE: Patients receive bevacizumab IV over 30-90 minutes on days -14, 1, 15, 29, and 42 and aldesleukin subcutaneously on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-40. Courses repeat every 8 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients achieving complete response after completion of study therapy may receive 1 additional course of therapy.
After completion of study therapy, patients are followed periodically.
