Trial Outcomes & Findings for Patient-Reported Erectile Recovery and Quality of Life Outcomes With Lyopreserved Placental Tissue Applied Directly Over Neurovascular Bundle During Nerve Sparing Radical Prostatectomy Versus Standard of Care (NCT NCT05366842)

NCT ID: NCT05366842

Last Updated: 2026-01-30

Results Overview

The primary outcome variable is the patient's score on the IIEF questionnaire (erectile function domain) at 1,3, 6, 9, 12, and 18 months post-surgery. A comparison of changes in the initial IIEF score will be evaluated to determine treatment efficacy. The IIEF contains 15 questions. A score of 0-5 is awarded to each of the 15 questions that examine the 4 main domains of male sexual function: erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Overall scores will be categorized as follows: * 1-10: Severe Erectile Dysfunction * 11-16: Moderate dysfunction. * 17-21: Mild to moderate dysfunction * 22-25: Mild dysfunction * 26-30: No dysfunction

SECONDARY outcome

Timeframe: 1, 3, 6, 9, 12 and 18 months post-surgery

Population: Data not collected. Study terminated before data collection

The following questionnaires will be combined into a composite index EPIC score. EPIC scoring involves linear standardization of the response for each questionnaire to a 0 to 100 scale. Using the item groupings for each health-related quality of life (HRQOL) Domain Summary Score or Subscale score, values are averaged for all items within a group to create the summary or subscale score. A higher score represents better HRQOL. EPIC scores will be compared at each time point. A clinically relevant increase for the sexual domain is 10-12 points. * The Quality of Erection Questionnaire (QEQ) assesses erection in terms of hardness, onset, duration, and changes in erection quality. There are 6 questions. * The Short Form Survey (SF-12) assesses 8 health domains: Physical Functioning, Role-Physical, Bodily Pain, etc with 1-2 questions per domain. * The MUSIC questionnaire assesses four domains: urinary, bowel, sexual and hormonal. Each domain consists of 2-4 questions.
