Spots Global Cancer Trial Database for Placebo-Controlled Trial of Urolithin A Supplementation in Men With Prostate Cancer Undergoing Radical Prostatectomy, URO-PRO Trial

Study Description

Brief 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.

Detailed 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 serum 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 tissue levels, which will be compared between arms using end-of-study tissue only). II. To compare the change in expression of cell cycle genes in prostate cancer tumor tissue from pre-study biopsy to radical prostatectomy in men receiving Uro-A supplements for 3 to 6 weeks and a control group of men receiving a placebo. III. To determine the effect of Uro-A supplements on change in 8-OHdG expression in benign and tumor-adjacent prostatic tissue from pre-study biopsy to radical prostatectomy (RP) following 3-6 weeks of therapy in comparison to a control group of men receiving a placebo. EXPLORATORY OBJECTIVES: I. To determine the effect of Uro-A supplements on circulating levels of high sensitivity C-reactive protein (hsCRP), TNF-alpha, and IL-6, as measured by change from baseline to end-of-study compared with the men receiving a placebo. II. To compare change in tumor gene expression patterns of Hallmark androgen signaling between study arms. III. To determine the effect of a 3-to-6-week intervention of urolithin A (Uro-A) supplements versus placebo on 8-OHdG H-index (percent staining positive at each score in a 0-3 scale) change in prostate cancer tumor tissue obtained by core needle biopsy at baseline and at radical prostatectomy after 3 to 6 weeks of therapy. IV. To collect stool samples for future analyses to determine the effect of Uro-A supplements on change in stool microbiome 16s ribosomal ribonucleic acid (rRNA) gene sequencing. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive urolithin A orally (PO) on study. Patients also undergo biopsy at time of surgery and collection of blood samples during screening and on study. Patients may also undergo collection of stool samples during screening and on study. ARM II: Patients receive placebo orally (PO) on study. Patients also undergo biopsy at time of surgery and collection of blood samples during screening and on study. Patients may also undergo collection of stool samples during screening and on study. Patients are followed up at 2 weeks after surgery.
