Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Donor Fecal Microbiota Transplantation Group
Subjects will receive a fecal microbiota transplantation (FMT) using stool from a donor
|
Single fecal microbiota transplantation using 50 gm of freeze-thawed donor stool
|
Placebo Comparator: Autologous Fecal Microbiota Transplantation Group
Subjects will receive a fecal microbiota transplantation (FMT) using their own stool
|
Single fecal microbiota transplantation using 50 gm of stool collected from the same individual

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of responders
Time Frame: 12 weeks
|
Number of subjects receiving the donor fecal microbiota transplantation identified as a responder defined as a decrease of ≥50 points in Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) from baseline. The Irritable Bowel Syndrome Symptom Severity Score scale has a possible range of scores from 0-500. Mild cases are classified as a score of 75-175, moderate cases are classified as a score of 175-300, and severe cases are classified as a score of >300. |
12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in level of fecal proteolytic activity
Time Frame: Baseline, 12 weeks
|
The level of fecal proteolytic activity will be measured at baseline and again at 12 weeks.
The proteolytic activity is measured using a standardized FITC Casein assay that relies on the activity of proteases in the sample to digest casein protein.
|
Baseline, 12 weeks
|
Changes in in vivo excretion of 2-24 hr lactulose excretion
Time Frame: Baseline, 12 weeks
|
Measured by permeability testing
|
Baseline, 12 weeks
|
Number of weekly responders
Time Frame: 12 weeks
|
Number of subjects to meet responder criteria of ≥30% decrease in average of worst abdominal pain in past 24 hours plus ≥50% decrease in the number of days per week with at least one stool that has a consistency of Type 6 or 7 (compared with baseline)
|
12 weeks
|
Global Adequate Relief Questionnaire
Time Frame: 12 weeks
|
Number of subjects to report adequate relief of IBS symptoms, measured by answering yes to question "In the past 7 days have you had adequate relief of your IBS symptoms?"
|
12 weeks
|
Alistipes putredinis proportion post-FMT
Time Frame: 12 weeks
|
Number of subject to have the bacteria Alistipes putredinis in stool sample after fecal microbiota transplantation (FMT)
|
12 weeks
