Fecal Microbiota Transplant (FMT) for Children with Gut Issues After Stem Cell Transplant

This study is looking at the safety and potential benefits of Fecal Microbiota Transplantation (FMT) for children up to 22 years old who have gastrointestinal (GI) problems after a stem cell transplant (Hematopoietic Cell Transplant or HCT). You might be able to join if you have steroid-resistant gut GvHD (Graft versus Host Disease, where donor cells attack your body) or other gut issues after your HCT. The FMT involves receiving microbiota preparation material either through a tube into your nose and stomach, or through a colonoscopy. Researchers will be watching closely for any serious or non-serious side effects within 30 days of the FMT. They also want to see how many interested people meet the study requirements.

Study design
This is an interventional study with a planned enrollment of 10 participants. It is not specified if it is randomized or blinded.
What's involved
Participants will receive Fecal Microbiota Transplantation (FMT) via naso-enteral tube and colonoscopy. A second FMT may be given at least 14 days after the first if symptoms haven't fully improved.
Compensation
Not stated in the trial record.
Follow-up
Researchers will monitor for adverse events for 30 days after FMT. They will also track how many people meet eligibility for up to 2 years.

Eligibility criteria

Inclusion

Age \< 22 years old.
Received an allogeneic HCT greater than or equal to 30 days prior to enrollment
Diagnosed with one of the following conditions:
Willing and able to provide informed assent/consent

Exclusion

Participant is at risk for aspiration pneumonia
History of anaphylactic allergy to foods that are not excluded from the stool donor diet
Female participant who is pregnant or nursing
History of previous FMT
Intra-abdominal surgery within 4 weeks of enrollment
At increased risk for peritonitis: presence of intra-abdominal devices (G-or GJ-tubes are acceptable), receiving peritoneal dialysis, or ascites
Concurrent abdominal radiation therapy
Any acute or chronic illness/condition as well as medication that in the opinion of the investigator puts the subject at greater risk from FMT or may confound the study results.
  • Proportion of participants with a serious adverse event occurring within 30 days following FMT30 Days

    Serious adverse events will be a primary outcome measure for the following groups: * FMT for treating a GvHD of the gut following HCT * FMT for treating HCT induced gut dysfunction

  • Proportion of participants with a non-serious adverse event occurring within 30 days following FMT30 Days

    Non-serious adverse events will be a primary outcome measure for the following groups: * FMT for treating a GvHD of the gut following HCT * FMT for treating HCT induced gut dysfunction

  • Proportion of participants expressing interest who meet eligibility2 years

    Participant eligibility will be a primary outcome measure for the following groups: * FMT for treating a GvHD of the gut following HCT * FMT for treating HCT induced gut dysfunction
