A Phase 2 Placebo-Controlled Trial of Urolithin A Supplementation in Men With Prostate Cancer Undergoing Radical Prostatectomy
National Cancer Institute (NCI)
Summary
This phase II randomized control trial assesses the effect of Urolithin A (Uro-A) supplementation compared to placebo in men with biopsy-confirmed prostate cancer undergoing radical prostatectomy (RP) progressive disease. A total of 90 men will be accrued and randomized 1:1 to receive a 1000 mg daily dose of Uro-A in two 250 mg capsules PO BID or two placebo capsules BID daily for 3 to 6 weeks prior to RP. The primary endpoint is to determine the effect of Uro-A on decreasing prostate tumor tissue oxidative stress (measured by 8-OHdG) compared to placebo.
Description
PRIMARY OBJECTIVE: I. To determine the effect of a 3-to-6-week intervention of urolithin A (Uro-A) supplements versus placebo on 8-OHdG percent positive change in prostate cancer tumor tissue obtained by core needle biopsy in participants who undergo radical prostatectomy after 3 to 6 weeks of therapy. SECONDARY OBJECTIVES: I. To determine prostate tissue and plasma concentrations of Uro-A, urolithin sulfate and urolithin A glucuronide, as measured by change from baseline to end-of-study, in comparison to changes from baseline to end-of-study in a control group receiving a placebo (except t…
