Using ARISTA polysaccharide to reduce blood loss during prostate cancer surgery
Official title: PROSPECTIVE RANDOMIZED CONTROLLED TRIAL EVALUATING THE EFFICACY OF INTRAOPERATIVE ARISTA™ AH POLYSACCHARIDE APPLICATION ON THE POSTOPERATIVE BLOOD LOSS IN PATIENTS UNDERGOING ROBOTIC ASSISTED RADICAL PROSTATECTOMY FOR THE TREATMENT OF PROSTATE CANCER
Run by St. Antonius Hospital Gronau · NCT06822036 · Data updated 2026-11-12
This study is testing if using a special gel during prostate cancer surgery can help reduce blood loss and improve recovery for men having nerve-sparing surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men aged 45 to 68 with localized prostate cancer undergoing robotic-assisted radical prostatectomy with nerve-sparing techniques.
✕Probably not a fit
Patients with high-risk prostate cancer, prior local therapy, or significant psychological conditions may not benefit from this study.

What this trial studies
This clinical trial investigates the efficacy of applying ARISTA™ AH, a polysaccharide, during robotic-assisted radical prostatectomy (RARP) for patients with prostate cancer. The study aims to determine if this intervention can reduce postoperative blood loss and improve functional outcomes, such as erectile function and urinary continence. Eligible participants include men aged 45 to 68 with biopsy-proven prostate cancer who are undergoing nerve-sparing surgery. The trial will assess the impact of ARISTA™ AH application on surgical outcomes compared to standard procedures.
Why it matters
Potential benefit: If successful, this approach could significantly reduce blood loss during prostate cancer surgery and improve recovery outcomes for patients.
How similar studies have gone: Previous studies have shown promising results with similar interventions aimed at reducing blood loss in surgical procedures, suggesting potential for success in this trial.

For secondary resection of the neurovascular bundle and controlling bleeding, mono- or bipolar thermal application, clip application and suturing is allowed. * No surgical revision within 7d after RARP (Clavien Dindo classified complication ≥3b) * No definitive anastomotic partial or complete rupture (identified via cystogram within 30d after RARP)
