Shockwave Therapy and Platelet Rich Plasma for the Treatment of Erectile Dysfunction

University of Miami59 enrolled

Overview

The purpose of this research study is to evaluate whether the combination of Shock Wave Therapy (SWT) with Platelet Rich Plasma (PRP) is synergistic and can reverse the pathology of microvascular Erectile Dysfunction (ED) and enhance erectile function by improving vasodilation, and endothelial function

Patients using Intracavernosal Injection (ICI) for management of ED 8. Patients with generalized polyneuropathy, or neurological conditions irrespective of cause, such as severe diabetes, multiple sclerosis or Parkinson's disease. 9. Have a serious comorbid illness/condition/behavior that, in the opinion of the investigator, may compromise the safety or compliance of the subject or preclude successful completion of the study. 10.

Outcomes

Primary Outcomes

Number of Participants With Treatment Emergent Serious Adverse Events (TE-SAEs) During the Study Period.

A treatment emergent serious adverse event (TE-SAE) is defined as any serious adverse event for which there is a reasonable possibility that the investigational product caused the adverse event. For the purposes of safety reporting, "a reasonable possibility" means there is evidence to suggest a causal relationship between the study product/procedures and the adverse event.

Time frame: Baseline, Month 3

Secondary Outcomes

Change in IIEF-EF Scores

International Index of Erectile Function - Erectile Function Subdomain Score (IIEF-EF) is a 5-item subdomain self- evaluation questionnaire of erectile function with a total score ranging from 0-25 with the higher score indicating better erectile function. Score ranges are commonly interpreted as: Severe ED: 0-10, Moderate ED: 11-16, Mild ED: 17-21, No ED / Normal erectile function: 22-25. Change from Baseline at Month 6 reported.

Time frame: Baseline, Month 6

Percentage of Participants Achieving MCID in IIEF-EF at Any Post-treatment Timepoint in Each Group.

IIEF-EF is a 5-item subdomain self- evaluation questionnaire of erectile function with a total score ranging from 0-25 with the higher score indicating better erectile function. Mild Clinically Important Difference (MCID) is attained via an increase of 2 points in IIEF-EF score for participants with mild ED and an increase of 5 points for participants with moderate ED. Participants are counted as achieving MCID if they meet the criteria at either the Month 3 or Month 6 assessment (or both).

Time frame: Baseline, Month 3, or Month 6

Percentage of Participants Who Either Decrease or Discontinue Use of PDE5i After Three Months Post-therapy Compared to Control Group

The percentage of participants who report either a reduction in frequency of PDE5 inhibitor use or complete discontinuation of PDE5 inhibitors at 3 months following completion of the intervention, compared to the control group. PDE5 inhibitor use will be assessed through participant self-report. A decrease in use is defined as a reduction in dose or frequency. Discontinuation is defined as complete cessation of PDE5 inhibitor use. The percentage will be calculated as the number of participants meeting either criterion divided by the total number of participants in each group.
