Background and study aims
Lower urinary tract symptoms can greatly reduce the quality of life in men and cause issues with urinating. They can be a sign of a benign prostatic hyperplasic (BPH) or an enlarged prostate. Even today, the exact reasons underlying the development and progression of LUTS / BPH have not been fully understood. Recent studies have shown that chronic inflammation (swelling) represents a crucial part in BPH, probably determining the hyperplasia (enlargement) of prostate cells. The inflammatory cells in fact, produce growth factors such as VEGF or TGF- β , which can support the fibromuscular growth in BPH. This is treated by using medication that block the growth such as alpha-blockers and 5-alpha reductase inhibitors or combination therapy have been used to relief symptoms and to prevent complications. Other studies have demonstrated the significant benefits of the combination therapy if compared with individual single therapies. However, despite the improvement in symptoms, side effects (erectile dysfunction, ejaculatory disorders, loss of libido) may limit adherence (sticking to) to treatment. For these reasons, some phytotherapics (using herbs for treatment), like the lipid extract (LE) of Serenoa repens (SeR) , selenium (Se) and lycopene (Ly) are currently used with the aim of improving symptoms and to limit the possible adverse effects. The aim of this study is to evaluate the efficacy and tolerability of a combination therapy of phytotherapies versus the single therapies in patients with LUTS/BPH.
Who can participate?
Adult men aged between 55 to 80 years old who have LUTS/BPH
What does the study involve?
Participants are randomly allocated to one of three groups. Those in the first group receive Ser 320 mg, Ly and Se ( Profluss ®) 1 tablet per day for 1 year. Those in the second group receive tamsulosin 0.4 mg 1 tablet a day for 1 year. Those in the last group receive Ser 320 mg , Ly and Se ( Profluss ®) 1 tablet per day for 1 year + tamsulosin 0.4 mg 1 tablet per day for 1 year. Participants are assessed for IPSS, IPSS quality of life, IIEF-5, Qmax, post-void residual and ejaculation.
What are the possible benefits and risks of participating?
Participants may benefit from a reduction of IPSS and PVR and increase in Qmax and quality of life. Risks would

Scientific title | Serenoa repens, lycopene and selenium vs. tamsulosin for the treatment of (LUTS)/ (BPH): An Italian multicenter comparative randomized study between single or combination therapy |
Study acronym | PROCOMB |
Study objectives | To evaluate the efficacy and tolerability of the combination therapy between SeR, Ly and Se(Profluss ®) + tamsulosin versus the individual monotherapies with Ser, Ly and Se (Profluss ®) or tamsulosin in patients with LUTS/BPH. |
Ethics approval(s) | Polyclinic Hospital, University of Catania, 09 Oct 2011, ref: Identification Number 618 |
Health condition(s) or problem(s) studied | Benign prostatic hyperplasia (BPH) / lower urinary tract symptoms (LUTS) |
Intervention | Participants were randomized with a 1:1:1 ratio into three treatment arms each consisting of 75 patients: group A (Ser 320 mg, Ly and Se ( Profluss ®) 1 tablet per day for 1 year), group B (tamsulosin 0.4 mg 1 tablet a day for 1 year), group C (Ser 320 mg , Ly and Se ( Profluss ®) 1 tablet per day for 1 year + tamsulosin 0.4 mg 1 tablet per day for 1 year. |

Phase | Not Applicable |
Drug / device / biological / vaccine name(s) | Serenoa repens, lycopene and selenium, tamsulosin |
Primary outcome measure | Reduction of IPSS (≥ 3 points from baseline), a percentage reduction of IPSS (IPSS%) ≥ 25%, increase of Qmax (≥ 30% from the baseline) and the reduction of PVR in patients treated with SeR, Ly and Se (Profluss ®) + tamsulosin compared to those treated with SeR, Ly and Se (Profluss®) or tamsulosin monotherapies after 1 year |
Secondary outcome measures | Secondary endpoints of the study were considered the change in erectile function (assessed by the International Index of Erectile Function-5 questionnaire), prostate volume, serum PSA and QoL at 1 year |
