Terms in these criteria, in plain language(2)

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.

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.

What researchers measure

Primary outcomes

  1. Performance/Effectiveness - Improvement in Quality of Life scoring (OAB)

    International Consultation on Incontinence Questionnaire Overactive Bladder Quality of Life (ICIQ-OABqol): questions in each subscale are scored by a summed range of 0 to 100, with a higher score indicating better quality of life. Overall score ≥ 10 points from baseline to follow-up is indicative of a clinically meaningful improvement.

    Time frame: 3 months

  2. Performance/Effectiveness - Improvement in Fecal Incontinence Survey

    Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): includes 5 items (solid, liquid, gas, wears pad and lifestyle alteration) and 5 frequencies (never = 0, rarely = 1, sometimes = 2, usually = 3, always = 4). Scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.

    Time frame: 3 months

  3. Adverse event reporting (Safety)

    Device-related, procedure-related and all serious adverse events

    Time frame: 3 months

Secondary outcomes

  1. Performance/Effectiveness - Improvement in Quality of Life scoring (OAB)

    International Consultation on Incontinence Questionnaire Overactive Bladder Quality of Life (ICIQ-OABqol): questions in each subscale are scored by a summed range of 0 to 100, with a higher score indicating better quality of life. Overall score ≥ 10 points from baseline to follow-up is indicative of a clinically meaningful improvement.

    Time frame: 1 year

  2. Performance/Effectiveness - Improvement in Fecal Incontinence Survey

    Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): includes 5 items (solid, liquid, gas, wears pad and lifestyle alteration) and 5 frequencies (never = 0, rarely = 1, sometimes = 2, usually = 3, always = 4). Scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.

    Time frame: 1 year

  3. Performance/Effectiveness - Improvement in Quality of Life Survey (FI)

    Fecal Incontinence Quality of Life (FIQoL): includes four different subscales: lifestyle, coping/behavior, depression/self-perception and embarrassment. Subscale scores range from 1 to 5, with 1 indicating lower functional status of qualify of life.

    Time frame: 3 months, 6 months, 1 year

  4. Adverse event reporting (Safety)

    Device-related, procedure-related and all serious adverse events

    Time frame: 1 year
