NCT05048667

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • 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.

    Baseline, Month 3

Secondary Outcomes (3)

  • Change in IIEF-EF Scores

    Baseline, Month 6

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

    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

    Baseline, Month 3

Study Arms (2)

SWT plus PRP Group

EXPERIMENTAL

Participants will receive weekly Shockwave Therapy (SWT) and Platelet Rich Plasma (PRP) for 5 weeks. SWT will be administered weekly on Weeks 1, 2, 3, 4, and 5. PRP will be administered on Week 1 and Week 5.

Device: Shock Wave therapy (SWT)Drug: Platelet Rich Plasma (PRP)

Sham SWT plus Placebo Saline Group

PLACEBO COMPARATOR

Participants will receive weekly Sham Shockwave Therapy (SWT) and Placebo Saline Intracavernosal Injection (ICI) for 5 weeks. Sham SWT will be administered weekly on Weeks 1, 2, 3, 4, and 5. Placebo Saline ICI will be administered on Week 1 and Week 5.

Other: Sham SWTOther: Placebo Saline

Interventions

Each SWT will administer 720 shocks in the treatment arm. Total of 3600 shocks are given over 5 weeks treatment period.

SWT plus PRP Group

5 mL PRP will be administered via intracavernous injection

SWT plus PRP Group

Sham Shockwave Therapy will be administered in the sham arm.

Sham SWT plus Placebo Saline Group

5 mL Placebo saline will be administered via intracavernous injection in the sham arm.

Eligibility Criteria

Age30 Years - 80 Years
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Be Male
  • Be 30 to 80 years of age (inclusive).
  • Be able to provide written informed consent.
  • Have a diagnosis of ED due to organic origin for at least 6 months prior to consent.
  • Sexually active in a stable, heterosexual relationship of more than three months duration.
  • IIEF-EF score 12-25 at screening
  • Agree to attempt sexual intercourse at least 4 times per month for the duration of the study without being under the influence of alcohol or recreational drugs.
  • Agree to comply with all study related tests/procedures.

You may not qualify if:

  • Previous penile surgery of any kind (except circumcision and condyloma removal), such as penile lengthening, penile cancer surgery, penile plication, grafting.
  • Previous history of priapism or penile fracture
  • Abnormal morning serum testosterone level defined as a value lower than 300 ng/dL (±5%) (indicative of untreated hypogonadism), or greater than 1197 ng/dL (±5%).
  • Current or previous hormone usage, other than prescribed testosterone, clomiphene or thyroid medication. (Subjects with prior or current use of hormonal treatment for prostate cancer are also excluded.
  • Psychogenic ED as determined by study investigator.
  • Anatomical (Peyronie's Disease or penile curvature that negatively influences sexual activity) or neurological abnormalities in the treatment area.
  • Patients using Intracavernosal Injection (ICI) for management of ED
  • Patients with generalized polyneuropathy, or neurological conditions irrespective of cause, such as severe diabetes, multiple sclerosis or Parkinson's disease.
  • 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.
  • History of consistent treatment failure with Phosphodiesterase Type 5 (PDE5) inhibitors for therapy of ED.
  • Any history of significant psychiatric disease, such as bipolar disorder or psychosis, greater than one lifetime episode of major depression, current depression of moderate or greater severity. Patients who are currently using Selective Serotonin Reuptake Inhibitors (SSRI) or psychotropic medications.
  • Hemoglobin a1c \>9%.
