Study Description
Brief Summary:
In this placebo controlled study the safety and efficacy of Cernilton, a standardized pollen extract, in men with inflammatory chronic prostatitis-chronic pelvic pain syndrome was investigated. The purpose of this study is to determine whether Cernilton is safe and effective in patients with inflammatory chronic prostatitis-chronic pelvic pain syndrome.

Condition or disease Intervention/treatment Phase
Chronic Prostatitis Chronic Pelvic Pain Syndrome Drug: Cernilton Drug: Placebo Phase 3

Detailed Description:
We conducted a multicenter, randomized, double-blind, placebo-controlled trial to assess safety and efficacy of Cernilton, a standardized pollen extract, in men with inflammatory CP-CPPS (National Institutes of Health (NIH) type IIIA). Participants were randomized to Cernilton or placebo for 12 weeks and were evaluated using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) individual domains and total score, the number of leukocytes in post prostatic massage urine, the International Prostate Symptom Score (IPSS) and the sexuality domain of a life satisfaction questionnaire at baseline and after 6 and 12 weeks.
