Placebo-Controlled Trial of Urolithin A Supplementation in Men With Prostate Cancer Undergoing Radical Prostatectomy, URO-PRO Trial
What this study is about
This phase II randomly assigned 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.
View original scientific description
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.

Primary outcome measures
Percent positive change in 8-OHdG
Time frame: Baseline up to radical prostatectomy (RP) after 3 to 6 weeks of therapy
The primary endpoint will be analyzed using a linear regression model. Standard descriptive statistics, including mean, standard deviation, median and interquartile range for continuous variables, and frequency and percent for categorical variables, will be used to summarize baseline variables by treatment arm. Changes will be summarized similarly. Graphical techniques, including boxplots and histograms, will be used to examine the distribution and to assess assumptions made for the primary analysis.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants must have pathologically confirmed adenocarcinoma of the prostate with formalin-fixed paraffin embedded (FFPE) biopsy tissue available for analysis. Diagnosis can be any time in the six months prior to registration/randomization
- Participants \>= 18 years will be enrolled. Because no dosing or adverse event (AE) data are currently available on the use of urolithin A in participants \< 18 years of age, children and adolescents are excluded from this study
- Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
- Absolute neutrophil count \>= 1,000/microliter
- Platelets \>= 100,000/microliter
- Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN) Note: Higher total bilirubin levels (=\< 3 mg/dL) can be allowed if due to known benign liver condition, i.e. Gilbert's
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvat

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
