About this study

Official title: Safety and Clinical Performance Study of the ARTUS® Artificial Urinary Sphincter (AUS) for the Treatment of Stress Urinary Incontinence (SUI) Due to Intrinsic Sphincter Deficiency

This clinical investigation is designed as an interventional, prospective, non-randomized, open-label, single arm, multicentric and international study for obtaining CE marking.

The study will be the first performed with the ARTUS® medical device aiming to assess safety and performance and will be composed of three phases:

Read more
  • pilot phase (with safety analysis on the 10 first included subjects in 3 investigational sites),
  • pivotal phase (in up to 16 investigational sites with a follow-up until the 12-month post-device activation visit, including an interim analysis at 3-month post-device activation visit on performance and safety),
  • long-term phase (with a long-term follow-up until 10 years post implantation in up to 16 investigational sites).

The objectives is to assess safety and clinical performance of the ARTUS® for the treatment of Stress Urinary Incontinence at short and long-term.

  17. General Quality of Life assessed with EQ-5D-5L questionnaire

    The EQ-5D-5L consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).

    The descriptive system comprises five dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) of 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.

    The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.

    Measured: Baseline, 3, 6, and 12-month post-device activation visit, 2 years, 3 years, 4 years, 5 years, 6 years, 7 years, 8 years, 9 years, 10 years post-op

  18. Sexual Quality of Life assessed with the Male Sexual Health Questionnaire (MHSQ)

    The MSHQ is a 25-item self-administered questionnaire. It encompasses 3 scales: Erection scale (3 items), Ejaculation scale (7 items), Satisfaction scale (6 items), and 9 additional items addressing sexual activity, time since last sexual encounter, level and changes in sexual activity, and bother associated with sexual dysfunction. Response options consist of dichotomous (Yes/No) scales, as well as 5 and 6- point likert scales.

    Scores by dimension:

    • Erection scale: 0-15 (higher score =higher sexual functioning)
    • Ejaculation scale: 1-35 (higher score =higher sexual functioning)
    • Satisfaction scale: 6-30 (higher score =higher level of satisfaction)

    Measured: Baseline, 3, 6, and 12-month post-device activation visit, 2 years, 3 years, 4 years, 5 years, 6 years, 7 years, 8 years, 9 years, 10 years post-op

  19. Subject usability assessed by a 5-point scale

    Subject usability questionnaire completed by the subject from 1 (strongly agree) to 5 (strongly disagree)

    Measured: 3, 6, and 12-month post-device activation visit, 2 years, 3 years, 4 years, 5 years, 6 years, 7 years, 8 years, 9 years, 10 years post-op

  20. Subject satisfaction assessed by the PGI-I

  22. Subject recommendation assessed by 5-point scale

    Subject recommendation assessed by the question "Would you recommend ARTUS to a friend" with the 5-point scale answers where 1 = strongly agree and 5 = Strongly disagree

    Measured: 3, 6, and 12-month post-device activation visit, 2 years, 3 years, 4 years, 5 years, 6 years, 7 years, 8 years, 9 years, 10 years post-op

Model description
The subjects will be implanted with the ARTUS® medical device and then be followed up for 10 years post-implant, with the primary endpoints measured at 3-month post-device activation visit. As there is no comparator, there is no randomization and no blinding in the study. Clinical performance outcomes will be measured for each subject at baseline (before implantation) and post-implantation.

Questions about this trial

What is this clinical trial studying?

A study testing Artificial Urinary Sphincter implantation in people with Stress Urinary Incontinence, run by Myopowers Medical Technologies France SAS at 3 sites in 2 countries.

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 8 inclusion and 28 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: opening soon, as of the sponsor's last update on 19 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Spain, Czechia. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact David Phrakorhnkham (+33 (0)4 42 95 12 20, david.phrakornkham@affluentmedical.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in the 24-hour Pad Weight Test (time frame: 3 months post-device activation). 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 19 Sep 2022.
