Extension to Study of Effects of Pomegranate Extract on Rising PSA Levels After Primary Therapy for Prostate Cancer

Prostate Cancer Clinical Trial

Official title: A 48-Month Extension to the Randomized, Double-blind, Placebo-Controlled Study of the Effects of Pomegranate Extract on Rising Prostate-Specific Antigen Levels in Men Following Primary Therapy for Prostate Cancer

Status Active, not recruiting

Clinical Trial Summary

High concentrations of anti-oxidants in pomegranate seeds present a potential strategy to delay clinical prostate cancer progression and prolong the interval from primary treatment failure to hormonal ablation. This is a 48 month extension to the double-blind GUP-0205-1 study, to compare the effects of daily consumption of pomegranate liquid extract versus placebo on the absolute prostate-specific antigen (PSA) doubling time at the end of 12, 24, 36 and 48 months in male subjects who rolled-over from the GUP-0205-1 study.

Clinical Trial Description

The primary objectives are to compare the effects of daily consumption of pomegranate liquid extract versus placebo on the absolute prostate-specific antigen (PSA) doubling time at the end of 12,24, 36 and 48 months in male subjects who rolled-over from the GUP-0205-1 study. Secondary objectives are to determine the effect of the pomegranate treatment on the change in PSA doubling time from baseline to each 12-month visit, to determine the time to tumor recurrence, to assess the tolerability and toxicity of the pomegranate treatment and to determine the effect of the pomegranate treatment on response rates for positive PSA doubling times and for declining post-treatment PSA levels (negative doubling times). ;
