Fecal Microbiota Transplantation for Chronic Granulomatous Disease-Associated Colitis
What this study is about
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. Objective: To see if FMT can reduce inflammation in the colon.

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. 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.
Interventions
DRUG
MTP 101-LF
Each unit of MTP-101-LF contains approximately 35 mL of fecal transplant product. Participants will receive approximately 32 mL via colonoscopy.
Primary outcome measures
Difference in fecal calprotectin pre FMT and within 1 month post FMT.
Time frame: Within 1 month
To evaluate the change in intestinal inflammation pre-FMT vs post FMT
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- In order to be eligible to participate in this study, an individual must meet all of the following criteria:
- Aged \>=10 to \<=60 years.
- Able to provide informed consent (for ages \>=18 years) or has a parent or guardian who can provide informed consent on their behalf (for ages \<18 years).
- Have confirmed prior diagnoses of CGD and CGD-AC (or CGD-IBD with evidence of colitis on colonoscopy).
- Fecal calprotectin level \>=200 microgram/g.
- HBI score \>=5 (to be evaluated on Day 1).
- No planned change in systemic antibiotic regimen for CGD for 1 month preceding FMT.
- No planned escalation in CGD-IBD treatment for 1 month preceding FMT.
- If taking monoclonal antibodies for CGD-IBD, the dose must be stable for 12 weeks with no planned escalation.
- Participants who can become pregnant must agree to use at least one highly effective method of contraception when engaging in sexual activities that can result in pregnancy, starting at screening until the end of study participation. Highly effective methods include a barrier (eg, condom, diaphragm, cervical cap), intrauterine device, or hormonal contraception.
Exclusion criteria
- An individual who meets any of the following criteria will be excluded from participation in this study:
- Evidence of acute GI infection, including active GI abscesses.
- Presence of C difficile toxin gene in stool, as identified by PCR, in screening period.
- History of intestinal obstruction definitively related to CGD-IBD.
- History of fistulizing CGD-IBD or CGD-IBD intra-abdominal abscesses.
- History of CGD-IBD related non-transversable intestinal strictures.
- History of AEs attributable to previous FMT.
- History of significant liver disease (eg, biopsy-proven nodular regenerative hyperplasia), including portal hypertension or cirrhosis.
- Pregnant or breastfeeding.
- History of severe food allergy.
- Any contraindication to having colonoscopy under anesthesia.
- Any condition that, in the opinion of the investigator, contraindicates participation in this study.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
