Treatment and study plan

Axonics SNM System INS Model 5101 (R20)

Device

Participants treated with the rechargeable Axonics SNM System Model 5101 also referred to as R20. Commercial devices used in this study are within their intended use as described in each geography's approved instructions for use.

Primary outcomes

  1. Performance/effectiveness - Improvement in Quality of Life scoring (FI)

    Time frame: 3 months

    Short-term FI improvement demonstrated by Cleveland Clinic Florida Fecal Incontinence Score (CCF-FIS). Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.

  2. Performance/effectiveness - Improvement in patient satisfaction scoring (FI)

    Time frame: 3 months

    Short-term FI improvement demonstrated by Participant Satisfaction with Treatment and Charging Questionnaire. Participants will indicate satisfaction with SNM therapy for treatment of their FI symptoms based on a 7-point Likert scale ranging from "Very satisfied" to "Very dissatisfied".

Secondary outcomes

  1. Performance/effectiveness - Improvement in Quality of Life scoring (FI)

    Time frame: 12 months, 24 months

    Demonstrate any improvement in CCF-FIS at 1-year and 2-years post-implant compared to baseline. Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.

  2. Performance/effectiveness - Improvement in Quality of Life scoring (FI)

    Time frame: 3 months, 12 months, 24 months

    Demonstrate an improvement in Fecal Incontinence Quality of Life (FIQOL) at 3 months, 1-year, and 2-years post-implant compared to baseline. 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.

  3. Performance/effectiveness - Improvement in patient satisfaction scoring (FI)

    Time frame: 12 months

    Participant Satisfaction with Treatment and Charging Questionnaire at 1-year post-implant compared to baseline. Participants will indicate satisfaction with SNM therapy for treatment of their FI symptoms based on a 7-point Likert scale ranging from "Very satisfied" to "Very dissatisfied".

  4. Adverse event reporting (Safety)

    Time frame: 3 months, 12 months, 24 months

    Device related, procedure-related and all serious adverse events
