Assessing Uniqueness of Inflammatory Bowel Disease Related Microbiome-derived Biomarkers

Study Purpose

To assess the differential expression of IBD-related microbiome-derived biomarkers including bacterial strains and peptides such as antimicrobial peptides (AMP) found in inner-colonic samples (HygiSample™) in comparison to home collected stool samples in patients with active IBD colonic disease. The HygiSample will be collected during a defecation-inducing high-volume (>40 L) colon irrigation bowel prep (HygiPrepⓇ).

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 80 Years
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - The patient's age is between 18 and 80 years old.
  • - For study arm - patients with known colonic IBD based on colonoscopic findings - diagnosed with either Ulcerative Colitis or Crohn's Disease scheduled for surveillance colonoscopy.
  • - For control arm - patients scheduled for routine colonoscopy without active IBD symptoms or IBD diagnosis.

Exclusion Criteria:

  • - The patient has an underlying condition that in the opinion of the investigator may adversely affect the patient's ability to understand, comply with, or follow protocol instructions.
  • - History of intestinal resection (appendectomy allowed) - Active Clostridium difficile colitis.
  • - Antibiotic use for 2 months prior to colonoscopy.
- The patient has any of the contraindications listed below: congestive heart failure, intestinal perforation, carcinoma of the rectum, fissures or fistula, severe hemorrhoids, abdominal hernia, renal insufficiency, cirrhosis, pregnancy, or recent colon, rectal, or abdominal surgery

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This study is a preliminary study aimed to assess the ability to differentially detect IBD-related microbiome-derived biomarkers in colon effluent samples collected using the Hygieacare System. The proposed sample size of 20 patients (10 in the control arm, 10 in the IBD arm), where each patient provides both stool and three inner-colonic samples is sufficient to provide preliminary results for such an assessment. Categorical variables will be summarized by frequencies and percentages, while quantitative variables will be summarized by descriptive statistics (mean, median, standard deviation, minimum, and maximum). The investigators will compare taxonomy and phylogeny biodiversity between the control and the IBD arms and between stool and colon effluent samples.

Arms & Interventions


Experimental: IBD

10 patients diagnosed with colonic IBD (5 diagnosed with Ulcerative Colitis and 5 diagnosed with Crohn's Disease) scheduled for a surveillance colonoscopy

Active Comparator: Control

10 patients scheduled for a routine screening colonoscopy who do not have a history of IBD symptoms or IBD diagnosis


Device: - Hygieacare System

The device is an FDA cleared colon irrigation device, it will be used according to clearance. The sampling of the colon effluent sampled is the are of study.
