Primary Outcome Measures:
  • National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) Total Score. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Change from baseline In NIH-CPSI at Week 12. Three separate domain scores are calculated as pain, urinary symptoms, and quality of life impact. NIH-CPSI total score uses a 0 to 43 scale; 0 best, 43 worse symptoms.
