Satraplatin and Bevacizumab in Treating Patients With Metastatic Prostate Cancer Previously Treated With Docetaxel

• Status: Completed
• Trial end date: 2012-11-01
• Target enrollment: 0
• Participant gender: Male

Summary

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. Drugs used in chemotherapy, such as satraplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving satraplatin together with bevacizumab may kill more tumor cells.

PURPOSE: This clinical trial is studying how well giving satraplatin together with bevacizumab works in treating patients with metastatic prostate cancer previously treated with docetaxel.
