About this study

Official title: Study of Non-Invasive Viberect® Penile Vibratory Stimulation Regimen to Enhance Recovery of Erectile Function/Rigidity and Urinary Control/Continence After Nerve Sparing Radical Prostatectomy (RP) for Clinically Localized Prostate Cancer.

The purpose of this study is to evaluate whether using penile vibratory stimulation with the Viberect handheld device can help the recovery of erections and urinary control after radical prostatectomy.

Read the detailed description

Prostate cancer screening programs have led to thousands of sexually healthy and continent men being diagnosed with prostate cancer every year. Recent literature suggests that up to 80% of these cancers are confined to the prostate gland. Currently, radical prostatectomy (RP) remains the best option for management of clinically localized prostate cancer in men with life expectancy greater than 10 years. Despite providing optimal cancer control, surgery can lead to quality of life (QOL) problems such as urinary incontinence and erectile dysfunction (ED). Refinement of surgical technique have improved sexual and continence outcomes; however erectile function lags behind other QOL measures by 1-2 years, and quality of returning erections is often inferior. This can have profound biological, marital, and psychological consequences in potent men undergoing RP.

ED is the inability to develop and maintain an erection for satisfactory sexual intercourse or activity. ED after nerve-sparing RP is related to a certain degree with functional impairment of cavernous nerves (CN) that travel along the prostate to the penis. This neuropraxia can last as long as 2 years. Pro-erectile nerve stimulus is vital for replenishment of corporal oxygen supply and other metabolic needs. Several histological analyses have demonstrated decreased smooth muscle number, cell-cell contact, venous leakage, collagen deposition, and additional harmful effects to corporal tissue after injury to CN.

Awaiting post-surgical neuropraxia recovery, urologists have proposed a proactive approach to use of oral, intraurethral or injectable pharmacotherapy, neuromodulation, or vacuum-assisted regimens in erectile rehabilitation programs. Several studies demonstrate variable functional improvement in erectile function. Unfortunately, prohibitive costs of medications, poor response, and pain from injectables or intraurethral application often lead to high dropout rates.

In addition to ED, a significant proportion of men after surgery develop and suffer from urinary incontinence (Stress, Urge, Mixed) requiring wearing pads with bothersome complaints persisting for months, even years after RP.

The primary objective is to assess the role of penile vibratory stimulation by the Viberect device in enhancing the recovery of erectile function/rigidity and urinary continence after RP for clinically localized prostate cancer. The difference in penile length will be compared in each arm.

The secondary objective is to obtain a formal risk analysis (RA). Other objectives are to assess the ease of use and acceptability of vibratory stimulation at home.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. change in erectile function

    The International Index for Erectile Function (IIEF) questionnaire will be administered. This is a 15 item tool; 6 ask questions addressing Erectile function over the previous 4 weeks.

Questions about this trial

What is this clinical trial studying?

A study testing Viberect device in people with Erectile Dysfunction Following Radical Prostatectomy and Urinary Incontinence of Non-organic Origin, run by Johns Hopkins University at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 24 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change in erectile function (time frame: baseline to 6 weeks after first device use). The study lists 20 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 May 2019.
