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.

Exclusion Criteria:

* Severe intellectual limitations preventing to fully understand the study concept and its content
* High risk prostate cancer (PSA ≥ 20 ng/ml or biopsy Gleason-Score ≥ 8 or suspected T4)
* Suspected bone or visceral metastases at preoperative imaging Neoadjuvant androgen deprivation therapy
* Any prior local therapy of the prostate (including subvesical deobstruction or radiation therapy)
* Any prior chemotherapy or colon/rectal surgery

* Any endocrine function disorder (not including diabetes)

SURGICAL AND PERIOPERATIVE EXLUSION CRITERIA:

* Accessory pudendal arteries (APA) preservation, if an APA is identified
* For a) nerve sparing and b) controlling bleeding in the area of the prostate bed and neurovascular bundles after prostate removal, no monopolar thermal application are allowed but suturing and clip application is allowed. 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)
