Trial summary

Fecal incontinence (FI) is a difficulty in storing gas, liquid stool or solid stool (bowel movement) in order to expel it at a proper time and place. Patients who suffer from FI may experience passive FI (difficulty in sensing stool in the rectum) or urgency (able to sense a bowel movement but cannot hold the stool… Read more about this study

About this study

Official title: Medtronic InterStim® Sacral Nerve Stimulation Therapy for Bowel Control: Fecal Incontinence Study

Fecal incontinence (FI) is a difficulty in storing gas, liquid stool or solid stool (bowel movement) in order to expel it at a proper time and place. Patients who suffer from FI may experience passive FI (difficulty in sensing stool in the rectum) or urgency (able to sense a bowel movement but cannot hold the stool until an acceptable time and place). FI is not a life-threatening disease, but it is often profoundly distressing and socially incapacitating.

If a patient is suffering with symptoms of chronic FI despite trying oral medications, biofeedback and/or other more conservative treatments, a patient may be eligible to participate in a clinical research study to evaluate the safety and effectiveness of sacral nerve stimulation for the treatment of chronic fecal incontinence. One hundred-twenty (120) patients will be implanted with medical devices and followed closely for twelve months, and then once a year after that until the study closes. There are up to 20 centers in the United States.

    Open label study. All subjects that qualify for the study will be implanted.

What is being measured

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

  1. Proportion of Subjects With at Least 50% Reduction in Number of Incontinent Episodes Per Week

    The primary efficacy objective was to demonstrate that at least 50% of subjects will achieve at least 50% reduction in the number of fecal incontinent episodes per week at 12 months post-implant compared to baseline. Subjects who achieve at least 50% reduction in the number of fecal incontinent episodes per week at 12 months post-implant compared to baseline are considered "successes."

    The observed therapeutic success rate is calculated as the proportion of implanted subjects who achieve at least 50% reduction in the number of incontinent episodes per week from baseline to twelve months.

    Measured: Baseline and 12 months

Secondary outcomes (6)
  1. Proportion of Subjects With at Least 50% Reduction in Number of Incontinent Days Per Week

    This secondary objective was to demonstrate that at least 50% of subjects achieved at least 50% reduction in the number of incontinent days per week at 12 months post-implant compared to baseline. Subjects who achieve at least 50% reduction in the number of fecal incontinent days per week at 12 months post-implant compared to baseline are considered "successes."

    The observed therapeutic success rate is calculated as the proportion of implanted subjects who achieve at least 50% reduction in the number of incontinent days per week from baseline to twelve months.

    Measured: Baseline and 12 months

  2. Change in Quality of Life From Baseline to 12 Months: Scale 1 - Lifestyle

    This secondary efficacy objective was to demonstrate improvement in Fecal Incontinence Quality of Life (FIQOL) scores at 12 months post-implant compared to baseline. Scales range from 1 to 5, with a 1 indicating a lower functional status of quality of life. The four component scales of the FIQOL instrument were evaluated separately.

    Measured: Baseline and 12 months

  3. Change in Quality of Life From Baseline to 12 Months: Scale 2 - Coping/Behavior

    This secondary efficacy objective was to demonstrate improvement in Fecal Incontinence Quality of Life (FIQOL) scores at 12 months post-implant compared to baseline. Scales range from 1 to 5, with a 1 indicating a lower functional status of quality of life. The four component scales of the FIQOL instrument were evaluated separately.

    Measured: Baseline and 12 Months

  4. Change in Quality of Life From Baseline to 12 Months: Scale 3 - Depression/Self-Perception

    This secondary efficacy objective was to demonstrate improvement in Fecal Incontinence Quality of Life (FIQOL) scores at 12 months post-implant compared to baseline. Scales range from 1 to 5, with a 1 indicating a lower functional status of quality of life. The four component scales of the FIQOL instrument were evaluated separately.

    Measured: Baseline and 12 Months

  5. Change in Quality of Life From Baseline to 12 Months: Scale 4 - Embarrassment

    This secondary efficacy objective was to demonstrate improvement in Fecal Incontinence Quality of Life (FIQOL) scores at 12 months post-implant compared to baseline. Scales range from 1 to 5, with a 1 indicating a lower functional status of quality of life. The four component scales of the FIQOL instrument were evaluated separately.

    Measured: Baseline and 12 Months

  6. Proportion of Subjects With at Least 50% Reduction in Number of Urgent Incontinent Episodes Per Week

    This secondary objective was to demonstrate that at least 50% of subjects achieved at least 50% reduction in the number of urgent incontinent episodes per week at 12 months post-implant compared to baseline. Subjects who achieve at least 50% reduction in the number of urgent fecal incontinent episodes per week at 12 months post-implant compared to baseline are considered "successes."

    The observed therapeutic success rate is calculated as the proportion of implanted subjects who achieve at least 50% reduction in the number of urgent incontinent episodes per week from baseline to 12 months.

    Measured: Baseline and 12 months

The record says: finished, as of the sponsor's last update on 24 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, Canada. 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?

Yes. Results are posted in the registry (first posted 30 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

What does the primary outcome measure?

Proportion of Subjects With at Least 50% Reduction in Number of Incontinent Episodes Per Week (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00200057, which also lists 2 linked publications.

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?
