Open-Label Phase IIb Efficacy Trial of Cancer Macrobeads Compared to Best Supportive Care in Colorectal Cancer Patients

This is a clinical research study of an investigational (FDA IND-BB 10091) treatment for patients with advanced colorectal cancer that no longer responds to standard therapies.
The treatment is being evaluated for its effect on tumor growth. It consists of the placement (implantation) of small beads that contain mouse renal adenocarcinoma cells (RENCA macrobeads). The cells in the macrobeads produce substances that have been shown to slow or stop the growth of tumors in experimental animals and veterinary patients. It has been tested in 31 human subjects with different types of cancers in a Phase I safety trial. Phase II studies in patients with colorectal, pancreatic or prostate cancers are in progress
