Brief summary
The study is a multi-center, randomized, placebo controlled trial with participants randomized into one of four groups: 1. placebo/usual care (educational pamphlet) 2. loperamide/usual care (educational pamphlet) 3. placebo/anal exercises with biofeedback 4. loperamide/anal exercises with biofeedback The primary outcome, change from baseline in St. Marks (Vaizey) Score at 24 weeks, will be compared between treatment groups using linear regression.
Detailed description
The goals of this trial are to compare the use of loperamide to oral placebo and to compare the use of anal sphincter exercise training with biofeedback to usual care (educational pamphlet) in the treatment of women suffering from fecal incontinence (FI). We will test the following null hypotheses: 1. there is no difference in outcomes between women randomized to loperamide and women randomized to oral placebo for treatment of FI; 2. there is no difference in outcomes between women randomized to anal sphincter exercises with biofeedback and women randomized to usual care (educational pamphlet) for FI treatment; 3. there is no difference between women randomized to both treatments together and women randomized to either FI treatment alone; and 4. there is no correlation between anal manometry measurements and digital anal squeeze strength or measures of FI severity and bother. A supplemental study, Stool Metabolome and Microbiome in Women with Fecal Incontinence in CAPABLe, will evaluate the stool metabolome and microbiome in women with fecal incontinence and unaffected age matched controls.
Interventions
Participants randomized to the loperamide group will begin with 2mg of loperamide/day. The participant will be administered the Patient Global Symptom Control rating scale (PGSC) to determine dose escalation. Participants who report inadequate control of stool leakage on the PGSC will be instructed to increase the daily dose of loperamide by 2 mg up to a maximum of 8 mg per day (1-4 capsules). Bothersome adverse events and resulting dose reduction will be based exclusively on the result of the Patient Global Tolerability Scale (PGTS). The daily dose will be decreased by 2mg to a minimum of 2mg every other day. If a PGSC score indicates inadequate control of stool leakage combined with a PGTS score indicating bothersome side effects, the participant will discontinue the study medication.
Participants randomized to the placebo arm will begin the a dose of one capsule per day and will be dose increased or dose decreased using the same algorithm described for the loperamide arm.
Participants will receive a formal anal exercises training program that can be easily applied in an office setting with minimal participant burden. Participants will attend six anal exercises with biofeedback sessions with trained personnel over a 12-week period for the 24-week study. Sessions will include introduction, standard patient education, and exercises using anal manometry-assisted biofeedback introducing concepts such as shaping, generalization and termination. The protocol uses strength and sensory training including urge resistance training. During the final twelve weeks, participants will perform anal exercises on their own. The sessions with interventionists will occur every other week for 12 weeks (total 6 supervised sessions).
Usual care consists of patients receiving an educational pamphlet on fecal incontinence created by the National Institute of Diabetes and Digestive and Kidney Diseases.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline St. Mark's (Vaizey) Score | 12 and 24 weeks | The primary outcome measure for all study arms is the change from baseline in St. Mark's (Vaizey) Score 24 weeks after treatment initiation to compare the marginal outcomes of anal exercise with biofeedback to usual care and loperamide to placebo. The St. Mark's (Vaizey) score, published in 1999, is commonly used in clinical studies and reports and was based on the Jorge-Wexner score but added two further items for assessment: the use of constipating medication and the presence of fecal urgency. Minimum score is 0 = perfect continence; maximum score is 24 = totally incontinent. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Colorectal-Anal Subscale of the Pelvic Floor Impact Questionnaire Short Form (CRAIQ) Score | 12 and 24 weeks | The Pelvic Floor Impact Questionnaire short form (PFIQ-7) measuring the impact of bladder, bowel, and vaginal symptoms on a woman's daily activities, relationships and emotions is composed of 3 scales of 7 questions each: the Urinary Impact Questionnaire (UIQ; range 0-100), the Pelvic Organ Prolapse Impact Questionnaire (POPIQ; range 0-100), and the Colorectal-Anal Impact Questionnaire (CRAIQ; range 0-100). The range of responses on the CRAIQ is 0-3 with (0) Not at all, (1) Somewhat, (2) Moderately, and (3), Quite a bit. Scores are calculated by multiplying the mean value of all answered questions for a scale by 100 divided by 3. The range of responses is: 0-100 with 0 (least negative impact) to 100 (most negative impact). Change = (Week \[12, 24\] Score - Baseline Score). Lower scores indicate better function / fewer symptoms. |
| Change From Baseline Accident-free Days at 12 and 24 Weeks | 12 and 24 weeks | Based on data collected from participant-completed diaries at baseline and 12 and 24 weeks, the outcome variable is computed as the difference in number of accident-free days at 12 and 24 weeks and the number of accident-free days at baseline. Only valid diaries were included in the analyses (e.g. completion of all 7 days for baseline and at least 3 complete days, not necessarily consecutive, for follow-up diaries). |
| Change From Baseline Pad-change Leaks Per Day at 12 and 24 Weeks | 12 and 24 weeks | Based on data collected from participant-completed diaries at baseline and 12 and 24 weeks, the outcome variable is computed as the difference in number of fecal incontinence episodes per day resulting in a change in pad, clothes or underwear at 12 and 24 weeks and the number of fecal incontinence episodes resulting in a change in pad, clothes or underwear at baseline. Only valid diaries were included in the analyses (e.g. completion of all 7 days for baseline and at least 3 complete days, not necessarily consecutive, for follow-up diaries). |
| Change From Baseline Pad-change Leaks Per Week at 12 and 24 Weeks | 12 and 24 weeks | Based on data collected from participant-completed diaries at baseline and 12 and 24 weeks, the outcome variable is computed as the difference in number of fecal incontinence episodes per week resulting in a change in pad, clothes or underwear at 12 and 24 weeks and the number of fecal incontinence episodes resulting in a change in pad, clothes or underwear at baseline. Only valid diaries were included in the analyses (e.g. completion of all 7 days for baseline and at least 3 complete days, not necessarily consecutive, for follow-up diaries). |
| Change From Baseline Total Number of Leaks Per Day at 12 and 24 Weeks | 12 and 24 weeks | Based on data collected from participant-completed diaries at baseline and 12 and 24 weeks, the outcome variable is computed as the difference in daily average FI episodes at 12 and 24 weeks and the daily average FI episodes at baseline. Only valid diaries were included in the analyses (e.g. completion of all 7 days for baseline and at 3 complete days, not necessarily consecutive, for follow-up diaries). |
| Change in Quality of Life on Colorectal-Anal Distress Inventory (CRADI) | 12 and 24 weeks | The Pelvic Floor Distress Inventory is a 20-question, validated, self-reported instrument used to evaluate pelvic floor symptoms. It consists of an overall scale (range: 0-300) comprised of 3 sub-scales: 1) Pelvic Organ Prolapse Distress Inventory (range: 0-100), 2) Colorectal Anal Distress Inventory (range: 0-100), and 3) Urinary Distress Inventory (range: 0-100). The range of responses on the CRADI is 1-4 with (1) Not at all, (2) Somewhat, (3) Moderately, and (4), Quite a bit. Scores are calculated by multiplying the mean value of all questions answered by 25 for the scale. The range of responses is: 0-100 with 0 (least distress) to 100 (most distress). Change = (Week \[12, 24\] Score - Baseline Score). Lower scores indicate better function / fewer symptoms. |
| Participants With Improvement in Patient Global Impression of Improvement (PGI-I) Score | 12 and 24 Weeks | The Patient Global Impression of Improvement (PGI-I) is a patient-reported measure of perceived improvement with treatment, as assessed on a scale of 1 (very much better) to 7 (very much worse). Included here are participants who had improvement as indicated by a rating of 1 (very much better), 2 (much better), or 3 (a little better). |

| Change From Baseline Volume of Air (mL) at Urge to Defecate at 12 and 24 Weeks | 12 and 24 weeks | Based on data collected from the manometry form, the outcome variable is computed as the difference in maximum tolerable rectal volume of air (mL) at 12 and 24 weeks and maximum tolerable rectal volume of air (mL) at baseline. |
| Change From Baseline Maximum Anal Pressures During Squeeze With the Catheter at the HPZ at 12 and 24 Weeks | 12 and 24 weeks | Based on data collected from the manometry form, the outcome variable will be computed as the difference in maximum anal pressures during squeeze with the catheter at the high pressure zone (HPZ) at 12 and 24 weeks and maximum anal pressures during squeeze with the catheter at the HPZ at baseline. |
| Change in Fecal Incontinence Severity Index (FISI) Score | 12 and 24 weeks | The Modified Manchester Health Questionnaire (MMHQ) includes the 4-item Fecal Incontinence Severity Index (FISI), which measures the severity of liquid, solid, mucus, or gas incontinence that occurs from 2 or more times per day, once per day, 2 or more times per week, once a week, to 1-3 times per month. Patient-weighted scores were used to determine severity and scores ranged from 0-61, with higher scores indicating worse fecal incontinence (FI) severity. An FISI score of 0 indicated continence. |

Change in Colorectal-Anal Subscale of the Pelvic Floor Impact Questionnaire Short Form (CRAIQ) Score
The Pelvic Floor Impact Questionnaire short form (PFIQ-7) measuring the impact of bladder, bowel, and vaginal symptoms on a woman's daily activities, relationships and emotions is composed of 3 scales of 7 questions each: the Urinary Impact Questionnaire (UIQ; range 0-100), the Pelvic Organ Prolapse Impact Questionnaire (POPIQ; range 0-100), and the Colorectal-Anal Impact Questionnaire (CRAIQ; range 0-100). The range of responses on the CRAIQ is 0-3 with (0) Not at all, (1) Somewhat, (2) Moderately, and (3), Quite a bit. Scores are calculated by multiplying the mean value of all answered questions for a scale by 100 divided by 3. The range of responses is: 0-100 with 0 (least negative impact) to 100 (most negative impact). Change = (Week \[12, 24\] Score - Baseline Score). Lower scores indicate better function / fewer symptoms.
Time frame: 12 and 24 weeks
