Is this trial a fit for you?

Likely a good fit

Ideal candidates are men aged 18 to 70 with non-metastatic adenocarcinoma of the prostate who are eligible for curative-intent radiation therapy.

Probably not a fit

Patients with metastatic prostate cancer or those outside the specified age range may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to identify the optimal dose of lisinopril for men with non-metastatic prostate cancer who are receiving radiation therapy. It will assess the impact of lisinopril on urinary symptoms and evaluate biomarkers associated with these symptoms. Participants will receive lisinopril tablets during their treatment, and their urinary health will be monitored throughout the study. The research is being conducted at the Wilmot Cancer Institute, focusing on improving patient outcomes related to radiation toxicity.

Why it matters

Potential benefit: If successful, this study could significantly reduce urinary complications in prostate cancer patients undergoing radiotherapy.

How similar studies have gone: While similar studies have explored the use of lisinopril in various contexts, this specific approach to urinary toxicity prevention in prostate cancer radiotherapy is novel.
