Safety and Tolerability of a Novel Implantable Device for the Treatment of Erectile Dysfunction
What this study is about
The goal of this clinical trial is to assess if a new device is safe to use as a potential treatment for erectile dysfunction following radical prostatectomy.
View original scientific description
The goal of this clinical trial is to assess if a new device is safe to use as a potential treatment for erectile dysfunction following radical prostatectomy. The main questions it aims to answer are: * Is the device safe? * Does the device works well? Are the participants satisfied with the device? Participants will be implanted with the device during the ongoing prostatectomy surgery and will be asked to complete the following tasks during 6 months follow-up: * Come to the hospital for follow-up visits, * Complete questionnaires, * Activate the device every day, * Measure erection hardness. Researchers will compare an implanted group (participants having the device) with a control group (participants not having the device) to see if the device works well.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Men of ages between 30-75 years with indication for nerve-sparing prostatectomy surgery;
- Cancer stage T1c and T2a;
- Grade Groups 1 and 2 as well as low volume Grade Group 3 (Gleason score 4 + 3 = 7), as determined by biopsy (2 cores or less GG3) or single index MRI lesion of GG3 disease;
- IIEF-15 erectile function domain score equal to or greater than 26;
- Men interested in minimizing the effect of radical prostatectomy on erectile function;
- Ability to read and understand patient information materials and willingness to sign a written informed consent.
Exclusion criteria
- Men with neurological disease, including a history of spinal cord injury or trauma;
- IIEF-15 erectile function domain score less than 26;
- Failure to demonstrate adequate nocturne erectile function prioi prostatectomy (nocturnal RigiScan measure);
- Men with PSA \> 20 ng/mL;
- History of ED, priapism and Peyronie disease;
- History of previous pelvic surgery, trauma or irradiation therapy;
- Currently have an active implantable device.
- Patient diagnosed with neurologic degenerative diseases that may negatively impact erectile functions;
- Identification of technical or clinical limitation to properly apply the use of nerve-sparing techniques during operation;
- Inability to understand and demonstrate device use instructions;
- Patients with insulin-dependent diabetes who suffer peripheral neuropathy or other diabetes associated complications;
- Patient unwillingness to engage in sexual activity;
- Patient is currently participating in another clinical investigation that would serve as a contraindication to implant a neurostimulator device to augment erectile function;
- Have participated in any drug or device trial in the last 4 weeks or plan to participate in any other drug or device study during the next 24 months;
- Possess any other characteristics that, per the investigator's judgment, may increase the risk or impair data collection for the procedure/study;
- Patient is a member of a vulnerable population (Vulnerable participants include those who lack consent capacity, including the mentally ill, prisoners, cognitively impaired participants, and employee volunteers).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
