Plain English Summary

Background and study aims
Chronic bacterial prostatitis is a bacterial infection of the prostate (a small gland located directly below the bladder in men). The aim of this study is to assess whether a capsule containing serenoa repens, cucurbita pepo, lycopene and selenium, used alongside antibiotics, can relieve the symptoms of chronic bacterial prostatitis and prevent reinfection.

Who can participate?
Men with chronic bacterial prostatitis

What does the study involve?
Participants are randomly allocated to one of two groups. Both groups receive antibiotic treatment for 15 days as a part of the regular treatment of chronic bacterial prostatitis. One group receives 6 months of treatment with one capsule per day of the study supplement (serenoa repens, cucurbita pepo, lycopene and selenium), while the other group receives one capsule per day for the same time period containing corn oil (placebo). The two groups complete symptom questionnaires and undergo urine flow tests and ultrasound scans at the start of the study and 1, 3, 6 and 12 months later.

What are the possible benefits and risks of participating?
The benefits include relief of the patients from chronic prostatitis symptoms and the improvement of their quality of life. There are no risks involved in participating in the study.

Where is the study run from?
Tzaneio Prefecture General Hospital (Greece)

When is the study starting and how long is it expected to run for?
September 2016 to June 2019

Who is funding the study?
Synapse Hellenic Pharmaceuticals & Services (Greece)

Scientific title

Serenoa repens, cucurbita pepo, lycopene and selenium as an adjunct to the treatment of chronic bacterial prostatitis with antibiotics: a placebo-controlled, double-blind, randomized clinical trial

Acronym

Study hypothesis

The study hypothesis is that:
1. During the 2nd and the 3rd patients' visits there will be a statistically significant difference in the overall NIH-CPSI Questionnaire Score favouring the Group A (serenoa repens, cucurbita pepo, lycopene and selenium group) in comparison with Group B (placebo - corn oil group)
2. In all four visits (1, 3, 6 and 12 months), there will be a statistically significant difference in the IPSS Questionnaire Score favouring the Group A (serenoa repens, cucurbita pepo, lycopene and selenium group) in comparison with Group B (placebo - corn oil group), when comparing the subgroup of patients rated as moderate symptoms during initial visit (Initial IPSS : 8-19)
3. After 12 months, there will be lower rates of bacterial reinfection symptoms in Group A (serenoa repens, lycopene and selenium) in comparison with Group B (placebo group)

Condition

Chronic bacterial prostatitis and lower urinary tract symptom (LUTS)

Intervention

Participants are randomised into two groups (block randomisation, computer generated algorithm).

Both groups receive antibiotic treatment for 15 days as a part of their regular treatment of chronic bacterial prostatitis. One group will receive 6 months of treatment with one capsule per day of the product (Serenoa Repens, Cucurbita Pepo, Lycopene & Selenium), while the other group will receive one capsule per day for the same time period containing corn oil (placebo).

The study will compare the groups' scores in the two basic questionnaires National Institute of Healths' Chronic Prostatitis Symptom Index (NIH-CPSI) and International Prostate Symptom Score (IPSS), as well as changes in the clinical measurements Qmax, residual volume and prostate volume observed 1, 3, 6 and 12 months after the initial visit.
