Phase 2
Recruiting
Conditions
Erectile Dysfunction Following Radical Prostatectomy
Prostate Cancer
Interventions
Biological: BioDFence G3 Placental Tissue Membrane
Procedure: Robot-Assisted Radical Prostatectomy
Registration Number
NCT05842057
Lead Sponsor
University of Miami
Brief Summary

The purpose of this research study is to evaluate if placing a dehydrated human amnion chorion membrane (dHACM) over the nerves after removal of the prostate during surgery (radical prostatectomy) will allow an earlier recovery of erectile function and urinary control after surgery.

Primary Outcome Measures
NameTimeMethod
Change in Erectile Function Recovery as Measured by EPIC26 Sexual Domain ScoreBaseline, 12 Months Post-RARP

Erectile function recovery among participants will be measured by the change in scores within the Sexual Domain of the Expanded Prostate Cancer Index Composite Short Form (EPIC26). The EPIC26 is a 26-item questionnaire used to measure health-related quality of life (HRQOL) among men with prostate cancer. The EPIC26 has five domains: Urinary Incontinence, Urinary Irritative/Obstructive, Bowel, Sexual, and Hormonal. Response options for each EPIC item form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale with higher scores representing better HRQOL.

Secondary Outcome Measures
NameTimeMethod
Change in Erectile Function Recovery as Measured by SHIM ScoreBaseline, 12 Months Post-RARP

Erectile function recovery among participants will be measured as the change in Sexual History Inventory for Men (SHIM). The SHIM is a health-related quality of life (HRQOL) questionnaire whose scores measure the severity of erectile dysfunction (ED) in men using points on a scale. The minimum score of 1 to 7 points indicates severe ED; a score of 8 to 11 points indicates moderate ED; a score of 12 to 15 points indicates mild-to-moderate ED; a score of 17 to 21 points indicates mild ED; and the maximum score of 22 to 25 points indicates no significant ED.

Number of Treatment-Related Adverse EventsUp to 12 months post-RARP

The number of treatment-related adverse events among participants will be assessed by treating physician using the Clavien-Dindo grading scale.

Change in Proportion of Participants with mild ED or Better as Defined by SHIM ScoreBaseline, 3 months, 6 months, 9 months, 12 months Post-RARP

Proportion of participants with mild ED or better as defined by a SHIM score greater than or equal to 17. The SHIM is a health-related quality of life (HRQOL) questionnaire whose scores measure the severity of erectile dysfunction (ED) in men using points on a scale. The minimum score of 1 to 7 points indicates severe ED; a score of 8 to 11 points indicates moderate ED; a score of 12 to 15 points indicates mild-to-moderate ED; a score of 17 to 21 points indicates mild ED; and the maximum score of 22 to 25 points indicates no significant ED.

Change in Rate of Urinary ControlBaseline, 3 months, 6 months, 9 months, 12 months Post-RARP

Rate of urinary control as measured by EPIC26 question 3 that reports the number of participants requiring no pads per day.

Change in Proportion of Men with Mild ED or Better as Defined by EPIC26 Sexual Domain ScoreBaseline, 3 months, 6 months, 9 months, 12 months Post-RARP

Proportion of men with mild ED or better as defined by an EPIC26 Sexual Domain score greater than or equal to 60. Response options for each EPIC item form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale with higher scores representing better sexual function.

Change in Proportion of Participants who Require the Use of More Invasive Erectile AidsBaseline, 3 months, 6 months, 9 months, 12 months Post-RARP

Proportion of participants who require the use of more invasive erectile aids (intra-cavernosal injection, vacuum pump, or penile prosthesis).

Change in Biochemical FailureBaseline, 3 months, 6 months, 9 months, 12 months Post-RARP

Biochemical failure among participants will measured as a prostate-specific antigen (PSA) level \> 0.2 ng/ml on two consecutive samples.

Change in Proportion of Participants with Erections Adequate for Penetration ≥ 50% of the timeBaseline, 3 months, 6 months, 9 months, 12 months Post-RARP

Proportion of participants with erections adequate for penetration greater than or equal to 50-percent of the time.
