Clinical Study to Investigate the Effectiveness of the TOPAS System to Treat Fecal Incontinence

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to demonstrate that the TOPAS System effectively treats fecal incontinence in women as measured by a 50% reduction in the number of FI episodes in a 14 day bowel diary at 12 months.

Detailed Description
-----------------
This is a prospective, multi-center, single-arm, open-label, two- stage, adaptive study conducted to obtain data to demonstrate the safety and effectiveness of the TOPAS system for the treatment of FI in women who have failed conservative therapy. It was approved by the FDA for up to 152 implanted subjects at up to 15 investigational sites in the US. Eight study centers are led by a Colorectal Surgeon and seven centers are led by an Urogynecologist. This study is being conducted in compliance with Title 21 CFR Parts 11, 50, 54, 56, and 812; the principles of GCP as set forth in the World Medical Association Declaration of Helsinki (2008); and the ISO standard 14155:2011 (Clinical investigation of medical devices for human subjects - Good clinical practice).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: TOPAS<br>TOPAS Treatment for Fecal Incontinence | Device: TOPAS Treatment for Fecal Incontinence<br>* The TOPAS Treatment for Fecal Incontinence is implanted using a minimally invasive trans-obturator approach; two needle passers deliver the sling assembly.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Responders | The primary endpoint for efficacy is the 14 day bowel diary documenting liquid or solid fecal incontinence episodes. A 50% reduction in the number of FI episodes is considered a treatment responder. | 12 Months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Fecal Incontinence Episodes | Number of fecal incontinence episodes in a 14 day period | 36 Month Follow-up Visit | 
| Change in Fecal Incontinence Days | Number of fecal incontinence days in a 14 day period | 36 Month Follow-up Visit | 
| Change in Urge Fecal Incontinence Episodes | Number of urge fecal incontinence episodes in a 14 day period | 36 Month Follow-up Visit | 
| Change in Wexner Symptom Severity Score | Wexner Symptom Severity Score for fecal incontinence (also known as the Cleveland Clinic Incontinence Score) as described by Jorge and Wexner, 1993 (Jorge JM, Wexner SD. Etiology and management of fecal incontinence. Dis Colon Rectum. 1993 Jan;36(1):77-97). Measured on a 0-20 scale with lower scores equal to less fecal incontinence. | 36 Month Follow-up Visit | 
| Change in Fecal Incontinence Quality of Life Score | Fecal Incontinence Quality of Life Score as described by Rockwood et al., 2000 (Rockwood TH, Church JM, Fleshman JW, Kane RL, Mavrantonis C, Thorson AG, Wexner SD, Bliss D, Lowry AC. Fecal Incontinence Quality of Life Scale: quality of life instrument for patients with fecal incontinence. Dis Colon Rectum. 2000 Jan;43(1):9-16; discussion 16-7). Four domains of lifestyle, coping, depression, and embarrassment. Measured on a 0-4 scale with higher scores equal to better quality of life. | 36 Month Follow-up Visit | 
| Change in Pelvic Floor Distress Inventory (PFDI-20) Scores | Short-form version of the Pelvic Floor Distress Inventory (PFDI-20) as described by Barber et al., 2005 (Barber MD, Walters MD, Bump RC. Short forms of two condition-specific quality-of-life questionnaires for women with pelvic floor disorders (PFDI-20 and PFIQ-7. Am J Obstet Gynecol. 2005 Jul;193(1):103-13). The short-form version of the Pelvic Floor Distress Inventory has a total of 20 questions and 3 scales (Urinary Distress Inventory, Pelvic Organ Prolapse Distress Inventory, and Colorectal-Anal Distress Inventory). Total PFDI score measured on a 0-300 scale with higher scores equal to greater pelvic floor distress. As with the Total PFDI Score, higher subscale scores equal greater pelvic floor distress, on a 0-100 scale. | 36 Month Follow-up Visit | 
| Change in Pelvic Floor Impact Questionnaire (PFIQ-7) Scores | Short-form version of the Pelvic Floor Impact Questionnaire (PFIQ-7) as described by Barber et al., 2005 (Barber MD, Walters MD, Bump RC. Short forms of two condition-specific quality-of-life questionnaires for women with pelvic floor disorders (PFDI-20 and PFIQ-7. Am J Obstet Gynecol. 2005 Jul;193(1):103-13). The short-form version of the Pelvic Floor Impact Questionnaire has a total of 7 questions and 3 scales (Urinary Impact, Pelvic Organ Prolapse Impact, and Colorectal-Anal Impact). Total PFIQ score measured on a 0-300 scale with higher scores equal to greater pelvic floor impact. Subscales scored on 0-100 scale and the higher the score the greater pelvic floor impact, exactly like the Total PFIQ score. | 36 Month Follow-up Visit | 
| Change in Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) | Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) as described by Rogers RG, Coates KW, Kammerer-Doak D, Khalsa S, Qualls C. A short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Int Urogynecol J Pelvic Floor Dysfunct. 2003 Aug;14(3):164-8; discussion 168. Measured on a 0-48 scale with higher scores equal to better sexual function. | 36 Month Follow-up Visit | 
| Change in Numeric Pelvic Pain Scale (NPPS) | Numeric Pelvic Pain Scale (NPPS) adapted from McCafferty M, Pasero C. Pain: Clinical Manual. 2nd ed. Philadelphia: Mosby Inc.; 1999. Chapter 3, Assessment Tools; p. 58-75. The NPPS is scored on a 0-10 scale with higher scores indicating more severe pain. Since the NPPS was introduced later in the study, earlier implanted subjects did not have the baseline NPPS score and a change from baseline could not be calculated. | 12 Month Follow-up Visit |
