Trial summary

Prostate adenoma or benign prostatic hypertrophy (BPH) is a benign disease of the prostate gland. It results in an increase in the volume of the prostate area located in contact with the urethra. Compression of the prostatic urethra by the adenoma can cause lower urinary tract disorders. Read more about this study

About this study

Prostate adenoma or benign prostatic hypertrophy (BPH) is a benign disease of the prostate gland. It results in an increase in the volume of the prostate area located in contact with the urethra. Compression of the prostatic urethra by the adenoma can cause lower urinary tract disorders.

The classic treatments in case of failure of medical treatment are endoscopic resection of the prostate and adenomectomy, but these techniques are characterized by a significant hemorrhagic risk that may require transfusions and prolonged hospitalization.

Minimally invasive treatments with low morbidity have been developed to overcome these drawbacks. They allow to propose a therapeutic solution adapted to patients: not tolerating their medical treatment, wishing to keep antegrade ejaculation, elderly and/or frail, at risk of bleeding, wishing an ambulatory treatment, refusing the conventional surgical techniques.

The Focal One® device was developed to treat prostate cancer using ultrasound energy. This energy is delivered through a probe placed in your rectum. Connected to this probe, an ultrasound machine will allow your doctor to see precisely which part of your prostate is being treated. By heating the prostate tissue to a very high temperature in one treatment session, the energy delivered will then destroy the tissue. Ultrasound guidance coupled with the localized nature of the treatment allows the targeted area to be treated while respecting the prostate tissue and structures adjacent to the prostate and thus reducing side effects.

Treatment of prostate adenoma with HIFU would allow for localized destruction to reduce prostate volume. The reduction of the compression of the prostatic urethra thus obtained would allow an improvement of the urinary disorders. The treatment is performed transrectally under real-time ultrasound control, which allows the adjacent structures to be respected, thus preserving antegrade ejaculation and limiting the side effects.

What is being measured

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

    Measured: 3 months

Secondary outcomes (9)
  1. Evaluation of treatment performance by maximum urine output (Qmax)

    Measured: 1 and 3 months

  2. Evaluation of treatment performance by residual post-void volume (RPM)

    Measured: 1 and 3 months

  3. Evaluation of voiding symptomatology with IPSS questionnaire

    Measured: 1 and 3 months

  4. Evaluation of quality of urinary life with Qol-IPSS score

    Measured: 1 and 3 months

  5. Evaluation of quality of erection with IIEF-5 questionnaire

    Measured: 1 and 3 months

  6. Evaluation of ejaculation quality with MSHQ-SF questionnaire

    Measured: 1 and 3 months

  7. Evaluation of continence with ICIQ-SF questionnaire

    Measured: 1 and 3 months

  8. Evaluation of the global impression of improvement scale with PGI-1 questionnaire

    Measured: 1 and 3 months

  9. Evaluation of the change in the PSA rate

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing HIFU treatment in people with Benign Prostatic Hyperplasia, run by EDAP TMS S.A. at 1 site in France.

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 6 inclusion and 19 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: finished, as of the sponsor's last update on 5 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The safety of HIFU treatment will be assessed by analyzing adverse events (serious and non-serious) reported during follow-up. (time frame: 3 months). 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 5 Jun 2025.
