Registered 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.

What it tests, as registered

Urolithin A; Placebo

Registered summary

Background: As people age, the cells in the pancreas that produce insulin begin to release less of this hormone, and levels of blood glucose (sugar) rise. This can lead to illnesses such as diabetes. Urolithin A (UA) is a natural nutritional supplement that may improve how the body controls blood glucose. Objective: To learn if UA improves levels of insulin and other hormones that help control blood glucose. Eligibility: People aged 55 years and older with a body mass index of 27 or higher. Design: Participants will have 6 clinic visits over 8 weeks. Participants will be screened. The full summary is on the listing.

Registered summary

As the population ages, the growing prevalence of age-related diseases is creating substantial challenges for healthcare systems worldwide. Current therapeutic strategies often target individual diseases and decrease mortality without improving healthspan. The geroscience hypothesis suggests that targeting the ageing process itself could prevent, delay, or manage the severity of multiple age-related diseases concurrently, thereby improving overall healthspan and reducing healthcare burdens.
