Plain English Summary
Background and study aims
Benign prostatic hyperplasia (BPH) (prostate enlargement) and lower urinary tract symptoms (LUTS) are common conditions that affect older men. The prostate is a small gland found inside the pelvis of men between the penis and the bladder. If it becomes enlarged, it can put pressure on the bladder and interfere with urinating. More common symptoms of prostate enlargement include a frequent need to urinate, difficulty starting to urinate and problems in fully emptying the bladder. It is not known why some men’s prostate becomes enlarged, but it’s thought to be related to hormonal changes as a man gets older. Some studies have shown that chronic inflammation of the prostate can lead to enlargement of the prostate cells and development of BPH. There are some drug treatments available which help to block the inflammation of prostate cells and relieve symptoms of BPH. Also, there is some evidence that combining certain drugs can relieve symptoms of BPH better than standard single drug treatments. One treatment available for BPH is Tadalafil® tablets, which are said to help reduce symptoms of BPH and improve urine flow, but how well it works is still controversial. The aim of this study is to test a new combination drug called Profluss® to see if it works better at relieving the symptoms of BPH and LUTS than Tadalafil®.
Who can participate?
Men aged 50-75 with prostate enlargement.
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 (intervention group) are given Profluss® tablets and take one a day for 6 months. Those in group 2 (control group) are given Tadalafil® tablets and take one a day for 6 months. At the start of the study, all participants complete questionnaires and have urine tests used to assess BPH, then again at 1, 3 and 6 months.
What are the possible benefits and risks of participating?
Participating in this study may help patients reduce symptoms of BPH and LUTS. There is a possible risk of side effects related to the prescribed drugs, however all risks are fully discussed with participants before the start of the trial.
Where is the study run from?
University of Catania, G. Rodolico Hospital (Universitaria Policlinico di Catania - POG Rodolico) and 27 other hospitals in Italy
When is the study starting and how long is it expected to run for?

Condition
Benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS)
Intervention

2. Group B Tadalafil® 5mg 1 tablet a day for 6 months
Intervention type
Drug
Phase
Phase III/IV
Drug names
1. Serenoa repens 320mg, selenium and lycopene (Profluss ®)
2. Tadalafil® 5mg
Primary outcome measure
1. Mean change of international prostate symptom score (IPSS) and peak flow in patients treated with Profluss® or Tadalafil® 5mg. The study is designed as non-inferiority study with a 95% power and an equivalence margin of 0.5 for IPSS and of 0.8 for the peak flow.

4. International Index of Erectile Function (IIEF-5) score
Secondary outcome measures
Mean changes of post-void residual (PVR) volume in patients treated with Profluss® or Tadalafil® 5 mg at enrollment (visit 0), one month (visit 1), at 3 months (visit 2), at 6 months (visit 3)
