Not Applicable
Completed
Conditions
Bowel Incontinence
Registration Number
NCT01475474
Lead Sponsor
Renew Medical
Brief Summary

The purpose of this study is to determine whether the use of the Renew Insert is effective, tolerable and safe in the treatment of accidental bowel leakage due to bowel incontinence.

Detailed Description

Prospective, open label, single-arm, non-randomized, multi-center study designed to evaluate the efficacy, safety and tolerability of the Renew Insert in moderate-to-severe bowel incontinence patients: Minimum Wexner score of 12 AND at least weekly (score 3 or higher) leakage of solid and or liquid type stool.

Primary Outcome Measures
NameTimeMethod
Co-primary Effectiveness Endpoint: A Relative Percentage Change in Wexner Score (or Bowel Incontinence) Severity by Comparing Post-treatment Wexner Scores to Pre-treatment (End of Baseline Period) Wexner Scores.Wexner score was calculated at the end of the Baseline period (Weeks 1-4) to the end of the 12-Week Treatment Period (week 16).

The Wexner fecal incontinence scale takes into account five parameters that are scored on a scale from zero (absent) to four (daily) frequency of incontinence to gas, liquid, solid, use of pad, and quality of life. Full continence is a Wexner total of zero (0), whereas full incontinence is a Wexner total of 20.

This co-primary effectiveness endpoint is the mean % reduction in Wexner score from the baseline period to the end of the treatment period, which was calculated according to the following equation: % reduction in Wexner = 100% (baseline period Wexner - end treatment period Wexner) / (baseline period Wexner).

Co-primary Effectiveness Endpoint: A Relative Percentage Change in Episodes of Accidental Bowel Leakage (ABL) Determined by Comparing Treatment Results to Pre-treatment Results From the Baseline Period as Measured by Daily Diary Recordings.Reduction in accidental bowel leakage from Baseline (Weeks 1-4) through Treatment period (Weeks 5-16).

This co-primary effectiveness endpoint was calculated as a relative percentage of the baseline Accidental Bowel Leakage (ABL) using the following equation: % reduction in ABL = 100\*(baseline period ABL - treatment period ABL) / (baseline period ABL)
