Overview

About this study

The objective of this study is to compare safety and effectiveness of the Voro Urologic Scaffold in adult men undergoing robotic assisted radical prostatectomy as compared to control arm. The study is a multi-center, single blind, randomized, controlled trial. Up to 266 participants will be treated at up to 30 centers in the United States. The study will consist of a Baseline visit, implantation during robotic assisted radical prostatectomy (RARP), catheter removal, 6 weeks, 6 months, 12 months, 18 months, and 24 months.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

6. Presence of urethral stricture or bladder neck contracture
7. History of urethral stricture
8. Current or chronic urinary tract infection
9. Prior urologic outlet surgical or minimally invasive procedure (e.g., Transurethral resection of the prostate [TURP], Holmium laser enucleation of the prostate [HoLEP,] Rezum, etc.).
10. Prior pelvic radiation or anticipated need for radiation after radical prostatectomy
11. History of neurogenic lower urinary tract dysfunction

18. Current uncontrolled diabetes (i.e., hemoglobin A1c [glycated hemoglobin or glycosylated hemoglobin] >=7.5%)
19. Current overactive bladder defined as a score of > 8 on the Overactive Bladder Questionnaire (OAB-8) administered at the baseline visit
20. History of immunosuppressive conditions or on medications which modulate the immune system
21. Any significant medical history that would pose an unreasonable risk or make the participant unsuitable for the study per investigator discretion
22. Participant with planned concomitant surgery
23. Anterior fascial sparing radical prostatectomy
24. Retzius sparing radical prostatectomy
25. Participant currently participating in other investigational studies unless approved by the Sponsor in writing
26. Participant is, in the investigator's judgement, part of a vulnerable population, including but not limited to:

1. Prisoners
2. Individuals pending incarceration
