Overview
Brief Summary
This study will assess the difference in prostatitis symptoms in men with localized prostate cancer following brachytherapy taking Q-Urol relative to placebo.
Detailed Description
This is a Phase 2, double-blinded, placebo-controlled trial assessing the safety of Q-Urol use after brachytherapy placement in patients with localized prostate cancer. Patients will be randomized in a 1:1 ratio to receive Q-Urol/Placebo twice daily for 6 weeks after brachytherapy placement. Questionnaires will be administered pre- and post-treatment to assess the change in prostatitis symptoms and quality of life measures. The mean values between groups will be compared.

- •aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 3 × institutional ULN
- •Estimated creatinine clearance ≥ 30 mL/min by Cockcroft-Gault formula:

- •Subject has received systemic therapy intended for the treatment of prostatitis (including herbal supplements) ≤ 14 days of starting study treatment.
- •Subject has received a fluoroquinolone antibiotic (e.g. ciprofloxacin, norfloxacin, ofloxacin levofloxacin, etc.) ≤ 3 days of starting study treatment.
- •Subject is actively on anti-inflammatory medications for other medical conditions, unless approved by PI.
- •Subject has undergone transurethral resection of the prostate (TURP).

Arms & Interventions
Arm 1: Q-Urol
Patients will be randomized in a 1:1 ratio to receive Q-Urol, two capsules, twice daily for 6 weeks after brachytherapy placement. Questionnaires will be administered pre- and post-treatment to assess the change in prostatitis symptoms and quality of life measures. The mean values between groups will be compared.
Intervention: Q-Urol
Arm 2: Placebo
Patients will be randomized in a 1:1 ratio to receive Placebo, two capsules, twice daily for 6 weeks after brachytherapy placement. Questionnaires will be administered pre- and post-treatment to assess the change in prostatitis symptoms and quality of life measures. The mean values between groups will be compared.
Intervention: Placebo
Outcomes
Primary Outcomes
National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI)
Time Frame: up to 6 weeks after the start of study treatment
This outcome will report the mean score of the NIH-CPSI, a 13-item questionnaire. This questionnaire will report 4 sub-scores, Pain, Urinary Symptoms, Quality of Life (QOL) Impact, and Pain + Urinary score, and the total score. Pain: The sum of 6 items (0 No-1 Yes), one scale (0 Never-5 Always), and one scale (0 No Pain-10 Pain as bad as you can imagine); Range: 0-21, higher values indicating worse outcomes. Urinary Symptoms: The sum of 2 urine items (0 Not at all-5 Almost always); Range: 0-10, higher values indicating worse outcomes. QOL Impact: The sum of 2 items (0 None-3 A lot) and 1 scale (0 Delighted-6 Terrible); Range: 0-12, higher values indicating worse outcomes. Pain and Urinary sub-score: The sum of the Pan and Urinary Symptoms scores; Range: 0-31, higher values indicating worse outcomes. Total Score: The sum of all questions; Range: 0-43, higher values indicating worse outcomes. This outcome measure is assessed at 6 weeks after the start of study treatment.
