Clinical Trial Summary

One current hypothesis as to what limits duration of initial hormone response is the rapid emergence of hormone resistant prostate carcinoma cells. Suramin has shown effectiveness as a treatment for hormonally refractory prostate carcinoma. Survival was less in patients with high rather than low circulating androgen levels. Thus, suramin might slow the emergence of hormone refractory tumor cells while combined androgen ablation may maximize the effectiveness of suramin. In this trial, we will pilot this concept.


Clinical Trial Description

The purpose of this study is to assess the potential for combined androgen blockage (Leuprolide and Flutamide), given with suramin (a growth factor inhibitor) to improve the clinical outcome(s) in a cohort of patients with bulky metastatic prostate cancer. Combined androgen blockage is currently the standard of care for such individuals. Suramin has shown reproducible activity in individuals with androgen independent disease. Since these two approaches are independent of one another - on the molecular level, and in clinical results - it is hoped that the combination of these two approaches will result in improved response rates and in improved survival. ;
