On June 13th the U.S. Food and Drug Administration Warned of Infections From Fecal Microbiota Transplantation (FMT) Linked to a Patient’s Death

Dr. Peter Marks, director the Center for Biologics Evaluation and Research at the U.S. Food and Drug Administration stated, “While we support this area of scientific discovery, it’s important to note that fecal microbiota for transplantation does not come without risk,”

Two patients contracted severe infections, and one of them died, from fecal transplants that contained drug-resistant bacteria.

The agency said two patients received donated stool that had not been screened for drug-resistant germs, leading it to halt clinical trials until researchers prove proper testing procedures are in place.

After reports of serious, antibiotic-resistant infections linked to the procedures, the FDA wants “to alert all health care professionals who administer FMT [fecal microbiota transplant] about this potential serious risk so they can inform their patients.” said Dr. Peter Marks, director the Center for Biologics Evaluation and Research at the U.S. Food and Drug Administration.

Other samples from the same donor were tested after the patients got sick. The samples were found to harbor the same dangerous germs found in the patients, known as multi-drug-resistant organisms (MDRO). They were E. coli bacteria that produced an enzyme called extended-spectrum beta-lactamase, which makes them resistant to multiple antibiotics. The stool had not been tested for the germs before being given to the patients.

The F.D.A. on Thursday issued a warning to researchers that stool from donors in studies of fecal transplantation should be screened for drug-resistant microbes, and not used if those were present. It is also warning patients that the procedure can be risky, is not approved by the agency and should be used only as a last resort when C. difficile does not respond to standard treatments.

Dr. Marks said the agency was trying to strike a balance between giving patients who need the treatment access to it while also establishing safeguards to protect them from infection. In a statement, he said, “While we support this area of scientific discovery, it’s important to note that fecal microbiota for transplantation does not come without risk.”

Researchers are also looking into the use of fecal transplants to treat chronic gastrointestinal illnesses such as ulcerative colitis or irritable bowel syndrome.

The patients received treatment as part of a clinical trial, and the researchers conducting the trial reported the cases as adverse events to the F.D.A., which they are required to do. But the rules governing this kind of experiment prohibit the F.D.A. from revealing details about the treatment or who provided it.

FDA Safety Alert Regarding Use of Fecal Microbiota for Transplantation and Risk of Serious Adverse Reactions d/t Multi-drug Resistant Organisms

Important Safety Alert Regarding Use of Fecal Microbiota for Transplantation and Risk of Serious Adverse Reactions Due to Transmission of Multi-Drug Resistant Organisms

The Food and Drug Administration (FDA) is informing health care providers and patients of the potential risk of serious or life-threatening infections with the use of fecal microbiota for transplantation (FMT).  The agency is now aware of bacterial infections caused by multi-drug resistant organisms (MDROs) that have occurred due to transmission of a MDRO from use of investigational FMT.

Summary of the Issue

  • Two immunocompromised adults who received investigational FMT developed invasive infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E.coli). One of the individuals died.
  • FMT used in these two individuals were prepared from stool obtained from the same donor.
  • The donor stool and resulting FMT used in these two individuals were not tested for ESBL-producing gram-negative organisms prior to use. After these adverse events occurred, stored preparations of FMT from this stool donor were tested and found to be positive for ESBL-producing E. coli identical to the organisms isolated from the two patients.

Information for Health Care Providers and Patients

In July 2013, FDA issued guidance stating that it intends to exercise enforcement discretion under limited conditions regarding the IND requirements for the use of FMT to treat Clostridium difficile (C. difficile) infection in patients who have not responded to standard therapies. The guidance states that FDA intends to exercise enforcement discretion provided that the treating physician obtains adequate consent for the use of FMT from the patient or his or her legally authorized representative. The consent should include, at a minimum, a statement that the use of FMT to treat C. difficile is investigational and a discussion of its potential risks. FDA is informing members of the medical and scientific communities and other interested persons of the potential risk of transmission of MDROs by FMT and the resultant serious adverse reactions that may occur.

Patients considering FMT to treat C. difficile infection should speak to their health care provider to understand the potential risks associated with the product’s use.

Additional Protections for Investigational Use of FMT

  • Because of these serious adverse reactions that occurred with investigational FMT, FDA has determined that the following protections are needed for any investigational use of FMT:
    • Donor screening with questions that specifically address risk factors for colonization with MDROs, and exclusion of individuals at higher risk of colonization with MDROs.
    • MDRO testing of donor stool and exclusion of stool that tests positive for MDRO. FDA scientists have determined the specific MDRO testing and frequency that should be implemented.

Reporting Adverse Event

FDA encourages all health care providers administering FMT products to report suspected adverse events to the FDA at 1-800-FDA-1088 or http://www.fda.gov/medwatch.
