A Phase II Trial of Leuprolide + Flutamide + Suramin in Untreated Poor Prognosis Prostate Carcinoma

March 3, 2008 updated by: National Cancer Institute (NCI)
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.

Detailed 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.

Patients must have adequate hepatic function (bilirubin less than 1.5mg%).

If the patient has white cells in his urinalysis or other evidence of a urinary tract infection, this must be evaluated and appropriate therapy initiation prior to the initiation of therapy.
