Investigating prostate medication effects on gut microbiota

Prostate Medication, Metabolism and Gut Microbiota

PHASE4 · Turku University Hospital · NCT06001619

This study is testing how prostate medications affect the gut bacteria in men with prostate issues and whether those bacteria influence how well the medications work.

What this trial studies

This study aims to explore the relationship between prostate medications and gut microbiota in men with prostatic hyperplasia and prostate cancer. It will assess how hormonal therapies, such as 5-alpha reductase inhibitors and LHRH antagonists, influence gut microbiota composition and metabolic characteristics. The study will also evaluate how gut microbiota may affect patients' responses to these medications. Participants will receive specific dosages of medications while their gut microbiota and metabolic profiles are monitored over time.

Who should consider this trial

Good fit: Ideal candidates include men diagnosed with prostatic hyperplasia or prostate cancer who are willing to comply with study protocols.

Not a fit: Patients with a history of fecal transplantation or recent gastroenteritis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized treatment strategies for prostate conditions based on gut microbiota profiles.

How similar studies have performed: While some studies have suggested a link between gut microbiota and therapy responses in prostate cancer, this specific approach is relatively novel and not extensively tested.
