Study summary

The purpose of this study is to evaluate the safety and effectiveness of ELMIRON® in the treatment of chronic non-bacterial inflammation of the prostate gland.

Read the detailed description

The objective of this randomized, double-blind, placebo-controlled study is to determine the effectiveness and safety of ELMIRON® 100 mg three times per day for 12 weeks, as compared with placebo, in patients with chronic non-bacterial inflammation of the prostate gland. Safety evaluations will be assessed throughout the study. The hypothesis of the study is that ELMIRON® will be more effective than placebo, as based on the change in the total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score from baseline to the final visit (Week 12) and is generally well-tolerated. Patients will receive oral ELMIRON® 100 mg three times per day orally or matching placebo three times per day for 12 weeks.
