Brief Summary:
The purpose of this randomized clinical trial is to evaluate the efficacy and safety of the alpha adrenergic blocker Alfuzosin (Uroxatral) in men with relatively new onset of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Alfuzosin is a once daily (10 mg capsule), FDA approved medication for an indication in benign prostatic hyperplasia (BPH). The effectiveness of alfuzosin in improving lower urinary tract symptoms in patients with BPH has been documented in a number of placebo-controlled studies. A number of small studies have also suggested that alfuzosin ameliorates CP/CPPS symptoms through a similar alpha-blockade mechanism. This study will enable further testing of this hypothesis

Condition or disease Intervention/treatment Phase
Prostatitis Drug: Alfuzosin Drug: Placebo Phase 3

Detailed Description:

The two primary objectives of this study are:

  • To compare 12 weeks of treatment with alfuzosin versus placebo in newly-diagnosed, alpha-blocker naive CP/CPPS participants with respect to the primary endpoint in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI).
  • To evaluate the safety and tolerability of 12 weeks of alfuzosin in newly-diagnosed, alpha-blocker naïve CP/CPPS participants.

The proportion of "responders" in each treatment arm will be compared to evaluate the overall safety and efficacy of alfuzosin as compared to placebo. Approximately 270 eligible patients, 135 per treatment arm, will be randomized and followed for a period of twelve (12) weeks after randomization.

There will be four research-clinic visits during which data for the primary and secondary outcome measures will be collected: visit 1 involves screening, visit 2 involves collection of baseline data and randomization, visit 3 is the 6-week evaluation, and visit 4 is the 12-week evaluation of the primary end point.

Arm Intervention/treatment

Drug: Alfuzosin
Placebo Comparator: Placebo
10 mg of an identical-looking placebo once daily for 12 weeks
Drug: Placebo

Primary Outcome Measures :
  1. Number of Participants With Decline in Total Score ≥4 for the NIH-CPSI Total Score From Baseline to 12 Weeks [ Time Frame: Baseline and 12 weeks ]
    For the National Institutes of Health Chronic Prostatitis Symptom Index (NIHCPSI) total score, higher scores indicate more severe symptoms and scores range from 0 to 43. The primary outcome was a decline of at least 4 from baseline to 12 weeks

Secondary Outcome Measures :
  1. Global Response Assessment (GRA) [ Time Frame: 12 weeks ]
    The response rate for the global response assessment was based on marked or moderate improvement at 12 weeks using a 7 point scale (marked worsening, moderate worsening, no change, slight improvement, moderate improvement, marked improvement).

  2. Change in Subscales of the NIH-CPSI [ Time Frame: Baseline and12 weeks ]
    For the National Institutes of Health Chronic Prostatitis Symptom Index (NIHCPSI), higher scores indicate more severe symptoms (for the quality-of-life score, higher scores indicate a more negative effect). Score ranges are as follows: total score, 0 to 43; pain score, 0 to 21; urinary score, 0 to 10, quality-of-life score, 0 to 12; and average pain and urgency scores, 0 to 10.

  3. Change in Subscales of the McGill Pain Questionnaire [ Time Frame: Baseline and 12 weeks ]
    For the McGill Pain Questionnaire, higher scores indicate greater pain. Score ranges are as follows: total score, 0 to 45; sensory score, 0 to 33; affective score, 0 to 12.

  4. Change in Medical Outcomes Study Short Form 12 [ Time Frame: Baseline and 12 weeks ]
    For the Medical Outcomes Study Short Form Health Survey 12 (SF-12), higher scores indicate better quality of life. Score range for both the physical and mental component summaries is 0 to 100.

  5. Change in Hospital Anxiety and Depression Scale [ Time Frame: Baseline and 12 weeks ]
    For the Hospital Anxiety and Depression Scale, higher scores indicate greater anxiety and depression; range, 0 to 42.

  6. Change in International Index of Erectile Dysfunction (IIEF) [ Time Frame: Baseline and 12 weeks ]
    For the International Index of Erectile Function, higher scores indicate better sexual function; range, 0 to 75.

  7. Change in Male Sexual Health Questionnaire [ Time Frame: Baseline and 12 weeks ]
    For the Male Sexual Health Questionnaire, higher scores indicate better function with respect to erection and ejaculation and greater satisfaction with sexual life; range, 0 to 40.
