Urolithin A supplementation for men with prostate cancer before surgery

A Phase 2 Placebo-Controlled Trial of Urolithin A Supplementation in Men With Prostate Cancer Undergoing Radical Prostatectomy

Phase 2 Interventional National Cancer Institute (NCI) · NCT06022822

This study is testing if taking Urolithin A before surgery can help men with prostate cancer by reducing stress in their tumor tissue.

What this trial studies

This phase II randomized control trial evaluates the effects of Urolithin A supplementation compared to a placebo in men diagnosed with prostate adenocarcinoma who are scheduled for radical prostatectomy. A total of 90 participants will be randomly assigned to receive either 1000 mg of Urolithin A daily or a placebo for a duration of 3 to 6 weeks prior to their surgery. The primary goal is to assess the impact of Urolithin A on reducing oxidative stress in prostate tumor tissue, measured by changes in specific biomarkers. Secondary objectives include analyzing the concentration of Urolithin A and its metabolites in prostate tissue and plasma, as well as changes in gene expression related to cancer progression.

Who should consider this trial

Good fit: Ideal candidates are men aged 18 and older with biopsy-confirmed prostate adenocarcinoma who are scheduled for radical prostatectomy.

Not a fit: Patients with prostate cancer who are not undergoing radical prostatectomy or those under 18 years of age may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel dietary supplement approach to reduce oxidative stress in prostate cancer patients, potentially improving surgical outcomes.

How similar studies have performed: While the specific use of Urolithin A in this context is novel, similar studies exploring dietary supplements for cancer treatment have shown promising results.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Participants who have pathologically confirmed adenocarcinoma of the prostate with formalin-fixed paraffin embedded (FFPE) biopsy tissue available for analysis, including those on active surveillance. Most recent biopsy 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
* Human immunodeficiency virus (HIV)-infected participants on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
* For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
* Participants with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
* Participants on chronic suppressive antiviral therapy for herpes simplex virus (HSV) are eligible
* Scheduled to undergo RP in the next 3-6 weeks
* Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

* Participants with prior primary treatment or hormonal therapy for prostate cancer (PC)
* Participants with documented active alcohol and illegal substance dependency
* Participants already receiving urolithin A (Mitopure, commercially available in the United States), or pomegranate supplements. Note: Other supplements are allowed but must be documented
* Participants receiving any other investigational agents
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to urolithin A
* Uncontrolled intercurrent illness, or psychiatric illness/social situations that would limit compliance with study requirements
