Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Study arms

  • Experimental
    ARTUS

    The subjects will be implanted with the ARTUS Artificial Urinary Sphincter to treat Stress Urinary Incontinence

    Device: Artificial Urinary Sphincter ARTUS

Interventions

  • DeviceArtificial Urinary Sphincter ARTUS

    The subjects will be implanted by the ARTUS Artificial Urinary Sphincter (AUS). The device will be activated 6 weeks after surgery and the tightening will be adjusted by the investigators in order to reach continence.

What researchers measure

Primary outcomes

  1. Adverse Device Effect Incidence

    all adverse device effects (device and/or procedure related) occurring from the implantation up to the 3 months post-operative visit, with their occurrence, severity, and nature. These events will be analyzed and classified using the Clavien-Dindo classification grading system.

    Time frame: 3 months after implantation

Secondary outcomes

  1. Adverse Events Incidence

    all adverse events (including adverse device effect) occurring peri-operatively, 30 days after implantation and at 3, 6, 12 and 24-months post-operative with their occurrence, severity, and nature. All adverse events will be analyzed and classified using the Clavien-Dindo classification grading system

    Time frame: Day 30, 3 months, 6 months, 12 months and 24 months after implantation

  2. Revision Rate

    Proportion of subjects with a revision of the Artificial Urinary Sphincter

    Time frame: 30 days, 3 months, 6 months, 12 months and 24 months after implantation

  3. Explantation Rate

    Proportion of subjects with a definitive explantation of the Artificial Urinary Sphincter

    Time frame: Day 30, 3 months, 6 months, 12 months and 24 months after implantation

  4. Evolution of Renal Function

    Measure of the serum creatinine

    Time frame: Baseline, Day 1

  5. Evolution of the pain

    Measure of the pain using a 10-point numerical scale (from 0 no pain to 10 the maximum pain)

    Time frame: Day 1, Day 45, 3 months, 6 months, 12 months and 24 months after implantation

  6. Evolution of uroflowmetry

    measure of the voided urine per unit of time, the voided volume and the maximum flow rate

    Time frame: Baseline, 3 months after implantation

  7. Bladder Drainage

    measure of the post-void residual volume

    Time frame: Baseline, Day 1, 3 months, 6 months, 12 months and 24 months after implantation

  8. Device Deficiency

    Number of device deficiencies

    Time frame: Implantation, Day 1, Day 45, 3 months, 6 months, 12 months, 24 months after implantation

  9. Pad Weight Test

    Measure of the daily urine loss in pads during 3 consecutive days

    Time frame: Baseline, 3 months, 6 months, 12 months and 24 months after implantation

  10. Pads Usage

    Number of pads used per day

    Time frame: Baseline, Day 45, 3 months, 6 months, 12 months and 24 months after -implantation

  11. Evolution of Stress Urinary Symptoms

    Evolution of the International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI SF). The score ranges from 0 (no impact) to 21 (maximal impact).

    Time frame: Baseline, 3 months, 6 months, 12 months and 24 months after implantation

  12. Evolution of Urinary Symptoms

    Evolution of the Urinary Symptom Profile (USP). The score ranges from 0 (no symptom) to 9 (maximal symptoms) for the subscore linked to the Stress Urinary Incontinence; from 0 (no symptom) to 21 (maximal symptoms) for the subscore linked to the overactive bladder; from 0 (no symptom) to 9 (maximal symptoms) for the subscore linked to the dysuria.

    Time frame: Baseline, 3 months, 6 months, 12 months, 24 months after implantation

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2026; primary completion for Mar 2027, 9 months later.

Of 41 industry-sponsored interventional studies with no phase under Urinary Incontinence, Stress, half reached primary completion within 16 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 46. This study's planned 9 months is below that.

Counting every sponsor, half of 267 studies reached it within 19 months; a quarter within 9 and three quarters within 43.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
