E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess, for the first time in literature, changes in pressure flow study (PFS) and changes in molecular profile of prostatic tissue (inflammatory and tissue remodeling markers) in men treated for 12 weeks with tadalafil 5 mg compared with placebo and to correlate these data with changes in symptoms scores (IPSS, International Prostatic Symptoms Score) in men with LUTS secondary to BPH refractory to alpha blockers. |
Valutazione in pazienti affetti da BPH in trattamento con alfa-bloccanti (Tamsulosina 0.4mg/die) e in attesa di intervento di TURP o prostatectomia semplice dell’efficacia di 12 settimane di trattamento con tadalafil rispetto a placebo nel migliorare la sintomatologia LUTS e quella infiammatoria ad essa associata, utilizzando dei questionari validati che esplorano non solo la sintomatologia LUTS (questionario IPSS) ma anche quella infiammatoria (NHI-CPSI). |
|
E.2.2 | Secondary objectives of the trial |
Improvement of pressure flow study (PFS) parameters Volumetric change of the prostate Change in prostate inhomogeneity and in the number of prostatic macrocalcifications BPH-associated prostate inhomogeneity and presence of micro-calcifications will be assessed by using male genital tract male genital tract colour-Doppler ultrasonography. Variation in genic expression of prostatic inflammation markers BPH-associated prostate inflammation, fibrosis, and hypoxia will be measured by immunohistochemical and quantitative RT-PCR analyses of inflammatory-, fibrosis- and hypoxia-related markers. Variation in serum inflammation markers CRP (C-reactive protein) and ESR (Erythrocyte Sedimentation Rate Improvement in metabolic profile Metabolic parameters will be evaluated (glycaemia, insulinemia, total cholesterol, HDL, triglycerides, HbA1c, mean arterial pressure, waist circumference, body mass index) Variation in seminal plasma IL-8 levels Improvement in erectile function

Valutazione nei soggetti maschi adulti affetti da BPH in trattamento con alfa-bloccanti (Tamsulosina 0.4mg/die) e in attesa di trattamento chirurgico di TURP o prostatectomia semplice dell’efficacia del trattamento con tadalafil rispetto a placebo di: • variazioni del flusso urinario massimo (Qmax), flusso urinario medio (Qave), volume urinato (Vcomp (valori dello studio pressione/flusso (PFS)). Verrà eseguita un’ecografia addominale subito dopo l’uriflussimetria per determinare le variazioni del residuo post minzionale (PVR). • miglioramento dell’infiammazione prostatica BPH-associata valutata tramite le caratteristiche ultrasonografiche tipiche del processo prostatitico • miglioramento dell’infiammazione prostatica BPH-associata, la fibrosi e l’ipossia • miglioramento dei parametri metabolici • riduzione dei livelli di IL-8 nel liquido seminale. • miglioramento della funzionalità erettile

E.5 End points |
E.5.1 | Primary end point(s) |
Improvement of LUTS/BPH symptoms BPH-associated inflammatory symptoms will be assessed by using the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI). BPH-associated LUTS will be assessed by using International Prostate Symptom Score (IPSS).

E.5.2 | Secondary end point(s) |
Improvement of pressure flow study (PFS) parameters Maximum flow rate (Qmax), average flow rate (Qave), voided volume (Vcomp), post void residual volume (PVR) will be evaluated.
