About this trial

This is an interventional treatment trial for Fecal Incontinence focused on measuring low anal pressures, passive incontinence, bowel movements, sphincter muscle

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • 18 years of age
  • participants must experience 4 or more Fecal Incontinence (FI) episodes per 2 week period
  • participants must score >10 on Cleveland Clinic Fecal Incontinence Severity Scoring System (CCIS)

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Muscle Fiber Fragment (MFF) injections

Arm Description

autologous muscle fiber fragment injections, harvested in an autologous fashion from the quadriceps muscle, for the treatment of Fecal Incontinence (FI) symptoms in men and women with a demonstrated anal sphincter defect and who have failed conservative treatments

Outcomes

Primary Outcome Measures

Cleveland Clinic Fecal Incontinence Severity Scoring System (CCIS) scores (also termed the Wexner score)
fecal incontinence score from 0-20; where 0 is perfect continence and 20 is complete incontinence
Cleveland Clinic Fecal Incontinence Severity Scoring System (CCIS) scores (also termed the Wexner score)
fecal incontinence score from 0-20; where 0 is perfect continence and 20 is complete incontinence
Cleveland Clinic Fecal Incontinence Severity Scoring System (CCIS) scores (also termed the Wexner score)
fecal incontinence score from 0-20; where 0 is perfect continence and 20 is complete incontinence

Secondary Outcome Measures

Change in Fecal Incontinence Quality of Life (FI-QOL) scores
The Fecal Incontinence Quality of Life Scale is composed of a total of 29 items; these items form four scales: Lifestyle (10 items), Coping/Behavior (9 items), Depression/Self-Perception (7 items), and Embarrassment (3 items).
Anorectal Manometry (ARM) Pressure scores
Low resting pressure is defined as <50 mmHg during the anorectal motility exam performed with high-resolution catheter (Given, Atlanta, GA). Normal resting pressures range from 50 to 100 mmHg. A flexible catheter with solid-state pressure transducers is placed in the anal canal and rectum to obtain standard pressure measurements
Internal Anal sphincter (IAS) Pressure scores
Typical resting pressure in a healthy volunteer is 40 to 60 mmHg
Rectal Anal Inhibitory Reflex (RAIR) Pressure scores
Low resting pressure is defined as <50 mmHg during the anorectal motility exam performed with high-resolution catheter (Given, Atlanta, GA). Normal resting pressures range from 50 to 100 mmHg. A flexible catheter with solid-state pressure transducers is placed in the anal canal and rectum to obtain Rectal Anal Inhibitory Reflex (RAIR)
Fecal Incontinence Severity Index (FISI) scores
Participants who score closer to 61 are likely to have their quality of life severely impacted by the fecal incontinence they suffer from.

5. Study Description

Brief Summary
To regenerate functional anal sphincter muscle using muscle fiber fragments that contain muscle precursor cells (MPCs)
Detailed Description
The Study hypothesizes that efficient re-assembly of injected fragments within host muscle tissue along the fiber direction of native muscle will be induced. It is anticipated that these fiber fragments would integrate into the host vascular and neural network.
