Fecal Microbiota Transplant

March 20, 2026 updated by: Methodist Health System

The study will provide data to show the effectiveness of Fecal Microbiota Transplant in patients with recurrent Clostridium difficile infection.

Fecal Microbiota Transplant (FMT) is a procedure in which healthy colon contents of a carefully screened donor is inserted into the colon of a compromised patient. FMT is a procedure to replace beneficial bacteria that has been killed or suppressed, most commonly by use of antibiotics. Currently it is utilized as an experimental treatment for Clostridium difficile infection (CDI). This procedure is predicted to reduce the cost both financially and physically for the CDI patient and facility.

Detailed Description

Methodist Health System wishes to offer transplant services to our CDI populations which meet all criteria for recurrent intractable disease. The objective is to reduce the cost both financially and physically to patients and the facility, of living with chronic or recurrent CDI disease. This study is to provide treatment and demonstrate documented outcomes and success rates in a manner that protects both the patients and the facility. Of note this treatment is currently being provided by many facilities in Texas, under the FDA Investigational New Drug (IND) enforcement discretion.

The study will provide data to show the effectiveness of Fecal Microbiota Transplant in patients with recurrent Clostridium difficile infection. This study will only examine FMT as it is the only available therapy beyond antibiotic treatment. When patients are considered for FMT they have already failed traditional therapeutic medications.

Patients will be required to meet a specified criteria set forth for chronic or severe CDI infection. Chronic infection is defined as the third or greater episode of C Difficile infection, proven by a positive stool assay with previous documented treatments. Patients must be first treated with first line drug therapies which include vancomycin, metronidazole or fidaxomicin without cure. They must have been treated with at least one course of drugs over a six to eight week period of a vancomycin taper or vancomycin treatment followed by rifaximin for two weeks. Severe CDI infection is defined as refractory moderate to severe CDI diarrhea, with failing vancomycin drug therapy.

Patients with contraindicated co-morbidities will be excluded. Comorbidities include severe bowel disease which would preclude colonoscopy, severe underlying immune suppression or decompensated liver cirrhosis.

Patients will be under the care of a physician who is an identified investigator (sub-investigator) of this study for preparation, procedure and follow up care. Patients will be counseled by this physician regarding the risks and side effects of the procedure and transplant. Staff will only reinforce details from written materials given to patients. Questions outside of the written materials will be directed to the investigators for follow up.

Risks include, but are not limited to the following.

  • Transplant making no improvement in the course of their CDI.
  • Common side effects including transient gas, bloating and rectal irritation
  • Surgical risks which can include blood clots, excessive bleeding, allergic reactions and death. More common surgical risks are infection, drug reactions, bleeding, and perforation.
  • Transmission of antibiotic-resistant bacteria: These are resistant to one or more antibiotics. These bacteria could be transmitted through FMT and cause a serious infection. The FMT that you will receive is provided by a company called OpenBiome, where donors who provide stool for the FMT treatments undergo screening for certain antibiotic-resistant bacteria and clinical risk factors that would make their exposure to antibiotic resistant bacteria more likely. Individuals who test positive for these bacteria or have these risk factors are excluded from donating.

Patients will sign three informed consents. The first consent is to acknowledge the basis of the treatment is part of a research study (exhibit 1). The second consent) specifies that FMT is experimental in nature, and reviews the potential risks and benefits of the transplant. The third is the Methodist Health System "Disclosure and Consent" that is used for colonoscopy procedures.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Clostridium difficile infection
Clostridium difficile infection (CDI) is due to a toxin-producing bacteria that causes a more severe form of antibiotic associated diarrhea. The disease ranges from mild diarrhea to severe colon inflammation that can even be fatal.
