What this Trial Is About

Researchers are evaluating the preferred dose of lisinopril in men with non-metastatic prostate cancer who are undergoing radiation treatment. The study aims to assess how lisinopril affects urinary symptoms and biomarkers related to these symptoms during and after radiation therapy. This is an early phase 1, randomized trial sponsored by the University of Rochester. Participants will either receive radiation therapy alone or radiation combined with lisinopril tablets at escalating doses of 5 mg, 10 mg, or 20 mg taken once daily. The study compares these groups to understand the optimal lisinopril dose for preventing urinary toxicity after radiotherapy. Radiation may be given as primary, adjuvant, or salvage treatment, possibly with androgen deprivation therapy. During the 12-month study, researchers will monitor urinary symptoms using the Expanded Prostate Index Composite score and measure the presence of blood in urine. They will also track how many participants reach the 20 mg lisinopril dose. Participants will undergo assessments including blood tests and evaluations of kidney, liver, and blood function. The study includes follow-up to evaluate the safety and effects of lisinopril on urinary health after radiation treatment.
