About this study
Official title: A Pilot Study of Fecal Microbiota Transplantation for Chronic Granulomatous Disease-Associated Colitis
Background:
Chronic granulomatous disease (CGD) weakens the body's defense against germs. CGD can also damage the colon. It can cause inflammation (colitis) that disrupts the good bacteria. Placing good bacteria from donor stool into the intestine of a person with CGD (called fecal microbiota transplantation, or FMT) may help.
Read more
Objective:
To see if FMT can reduce inflammation in the colon.
Eligibility:
People aged 10-60 who have CGD and colitis, and the treatments they have tried are not helping or have side effects.
Design:
Participants will have a telehealth screening visit. They will have a medical record review and medical history. They will collect stool samples at home and mail them to NIH.
Participants will stay at the NIH hospital for 3-5 days. Each day, they will have the following:
Physical exam
Medical history and medicine review
Surveys about CGD and how it affects their life
Blood, stool, and urine tests
Participants will have a colonoscopy. They will be sedated. A long, flexible tube will be inserted into their rectum. The tube will deliver the FMT material to their colon. Small samples of intestinal tissue will be collected.
Participants may have an optional MRI of the digestive tract.
Participants will have 9 follow-up telehealth visits over 6 months. They will be asked about their symptoms and side effects. They will fill out short surveys. They will collect stool and urine samples at home. Up to 2 visits can be done in person. At these visits, they may have the option to have an MRI and another colonoscopy to get more tissue samples.
Participation will last for 6-7 months.
Read the detailed description
Study Description:
This is a prospective, single-site, single-arm, open-label pilot trial to evaluate the use of fecal microbiota transplantation (FMT) delivered by colonoscopy as a treatment for chronic granulomatous disease (CGD)-associated colitis (AC). Participants will be evaluated for changes in intestinal inflammation, the microbiome, and symptoms associated with CGD-AC. It is hypothesized that FMT will reduce intestinal inflammation as measured by fecal calprotectin within 1 month compared to baseline (pre-FMT); there will be associated changes in the underlying stool microbiome and improvement in clinical symptoms.
Primary Objective:
To evaluate the change in intestinal inflammation pre-FMT vs post-FMT.
Secondary Objectives:
- To evaluate the change in the stool microbiome pre-FMT vs post-FMT.
- To evaluate changes in clinical symptoms pre-FMT and post-FMT.
- Preliminary evaluation of the safety of FMT in CGD-AC.
Tertiary/Exploratory Objectives:
- To evaluate other markers of intestinal and systemic inflammation pre-FMT and post-FMT.
- To evaluate a washout period for beneficial effects of FMT on fecal calprotectin and the microbiome.
- To evaluate the effect of FMT on antibiotic resistance in CGD-AC.
Primary Endpoint:
Difference in fecal calprotectin pre-FMT within 1 month post-FMT.
Secondary Endpoints:
- Differences in alpha diversity, beta diversity, and relative abundance of taxa pre-FMT and within 1 month post-FMT. Assessment of engraftment of donor microbiome.
- Difference in Patient Reported Outcome-2 (PRO-2) pre-FMT and within 1 month post-FMT.
- Treatment-emergent adverse events (TEAEs).
Tertiary/Exploratory Endpoints:
- Changes in C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) pre-FMT and post-FMT; changes in Simple Endoscopic Score for Crohn s Disease (SES-CD) pre-FMT and post-FMT in those who undergo a second colonoscopy; changes in magnetic resonance (MR) enterography findings in those who undergo a second MR enterography.
- Changes in fecal calprotectin and microbiome indices over 6 months post-FMT.
- Changes in antibiotic resistance genes in stool microbiome pre-FMT and post-FMT.
- Being tested
- MTP 101-LF
- Keywords
- Microbiome, Inflammation, Fecal Calprotectin, Immunodeficiency

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing MTP 101-LF in people with Chronic Granulomatous Disease-associated Colitis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 31 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Suchitra K Hourigan, M.D. ((240) 627-3995, suchitra.hourigan@nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Difference in fecal calprotectin pre FMT and within 1 month post FMT. (time frame: Within 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Mar 2026.
