Brief summary
The investigators hypothesize that perturbations in the intestinal microbiota following allogeneic hematopoietic stem cell transplantation (HSCT) are essential for the development and propagation of acute graft-versus-host disease. Therefore, modification of HSCT recipients' gut microbiota using fecal transplantation from a healthy donor could be used to treat gut acute GVHD. The study evaluates safety and feasibility of fecal microbiota transplantation with frozen capsules from healthy donors for the treatment of steroid resistant or steroid dependent acute graft-versus-host disease of the gut.

Inclusion criteria
* Adults (ages 18 to 75 years) who underwent allogeneic hematopoietic stem cell transplantation (HSCT) and developed gut acute Graft-versus-Host Disease (aGvHD). * Participants have steroid-resistant or steroid-dependent gut aGvHD. * Steroid resistant gut aGvHD is defined as cases in which gastrointestinal symptoms do not improve within 7 days after initial steroid therapy (≥1 mg/kg of methylprednisolone) or clear progression after 5 days.) * Steroid-dependent gut aGVHD is defined as cases in which reduction of steroid dose was not possible due to exacerbation of gastrointestinal symptoms. * Participants may have undergone allogeneic HSCT for any diagnosis at any time prior to developing aGvHD, and are not restricted to any specific conditioning regimen or by the subsequent administration of donor lymphocyte infusion. * Participants should be able to give informed consent.
Exclusion criteria
* Participants may not have gut aGvHD which permits the tapering of steroid dose. * Participants may not have ongoing, uncontrolled infection (i.e. unresolved bacteremia, uncontrolled CMV infection). * Participants may not have ongoing enteritis primarily caused by enteropathy other than gut GvHD, excluding resistant clostridium difficile infection. * Participants may not have acute neutrophil count \< 500 cells/µL. * Participants may not have toxic megacolon * Participants may not have active gastrointestinal bleeding. * Participants may not be pregnant or lactating. * Participants may not be unable to swallow pills.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Serious adverse events | 28 days following FMT. | Participants will be evaluated for serious adverse events (SAEs) relating to FMT occurring within 28 days following transplantation. SAEs are defined as any adverse experience occurring during or after FMT that results in any of the following outcomes: death, life-threatening experience, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity or an important medical event events |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Non-serious adverse events | 28 days following FMT. | Participants will be evaluated for non-serious adverse events relating to FMT within 28 days following transplantation. Non-serious adverse events are defined as diarrhea, nausea and vomiting, fatigue and malaise, headache, and distension/bloating/abdominal discomfort/pain |
| Gut acute Graft-versus-Host Disease (aGvHD) response. | up to 28 days following FMT. | Participants will be evaluated on days 7 and 28 following transplantation for response to therapy. Response criteria for steroid-resistant patients is as follows: * Complete response: resolution of all gastrointestinal signs and symptoms * Partial response: decrease in severity of gut GVHD by at least one stage * Progression: Progressive worsening of gut GVHD * No change: No significant change in gut GVHD Response criteria for steroid-dependent patients is as follows: * Complete response: reduction of the steroid dose to 5 mg or less of prednisone (or a steroid equivalent) per day. * Partial response: a reduction of ≥40% in the dose of steroid * Progression: an increase of \>=10% in the steroid dose * No change: any other option |
| aGvHD severity | up to 28 days following FMT. | Participants will be evaluated on days 7 and 28 following transplantation for severity of aGvHD. aGVHD severity is graded by the International Bone Marrow Transplant Registry Severity Index grading system |
| Reduction in the dose of steroids. | up to 28 days following FMT. | The dose of methylprednisolone, or an equivalent GCS, will be evaluated on day 7, and 28. The change in the dose at day 28, adjusted to the type of GCS used. |
