Erectile Function

We perform a multicenter randomized controlled prospective study with superiority trial design, in which the polysaccharide ARISTA™ AH hemostat agent is applied to the neurovascular bundle areas after prostate removal, during Robot-assisted radical prostatectomy. We examine if such agent leads to a relevant clinical improvement indicated by higher postoperative hemoglobin levels compared to the control group. As an exploratory co-primary endpoint of interest, we examine erectile function after Robot-assisted radical prostatectomy based on IIEF-5 score between groups 3, 6 and 12 months after Robot-assisted radical prostatectomy

This is a single arm dose escalation trial of a mucoadhesive intraurethral polymer suspension of alprostadil (ST-04) and will investigate the efficacy of 3 dose levels of ST-04 in adult males with a clinical diagnosis of Erectile Dysfunction (ED). This study aims to determine if ST-04, with or without sildenafil, will improve erectile function (EF) compared to baseline. Participants in this study will receive ST-04, a new formulation containing the vasodilator, alprostadil which is known to be an effective drug in treating erectile dysfunction. ST-04 will be dispersed along the urethra, forming a hydrogel which adheres to the lining of the urethra with the goal of penile tumescence and erection. Participants may receive up to 3 dose level escalations of ST-04 over a 12-week period, for a total of up to 11 administrations of ST-04. Dose escalation may also be done with and without sildenafil.

This prospective randomized controlled trial (RCT) is designed to provide high level evidence on the efficacy of Low-intensity Extracorporeal Shock Wave Therapy (Li-ESWT) in the treatment of post-Robot-Assisted (RA) Radical Prostatectomy (RP) erectile dysfunction (ED) in addition to PDE5 inhibitors (PDE5i) versus PDE5i alone. Our hypothesis is that early andrological rehabilitation that combines Li-ESWT and PDE5i could lead to faster and better recovery of valid erections for intercourse, with a greater rate of postoperative International Index of Erectile Function-5 (IIEF-5) compared to patients receiving PDE5i alone.
