FMT Treatments and Eligibility

Fecal microbiota transplantation (FMT) is a promising therapy for patients with recurrent C. difficile infections. Interested in learning more? The information below will help determine if you’re eligible for an FMT.

What is FMT?


FMT is an investigational therapy that is permitted under certain circumstances by the U.S. Food and Drug Administration (FDA). Currently, you must consult your doctor about whether FMT is an appropriate option for you.

Introduction to FMT

Within all of us is a community of bacteria known as the microbiome. These bacteria help our bodies to digest food, fight infections, and perform other key functions that keep us healthy.

Fecal microbiota transplantation (FMT) is a medical procedure that transfers the microbial community from a screened, healthy donor into a patient’s gut to help treat their illness. This procedure is typically performed through a colonoscopy.

Clinical trials have demonstrated that FMT successfully treats 80-90% of antibiotic resistant C. difficile infections.

Using FMT to Treat C. difficile Infections

Most patients with C. difficile are infected after receiving antibiotics for an unrelated illness.

Although antibiotics are powerful and life-saving medications, they may also disrupt the healthy bacteria that normally prevents the growth of infectious microbes like C. difficile.

FMT repopulates a patient’s damaged microbiome with a diverse community of microorganisms that limits the ability for C. difficile to find the space and nutrients to grow.


What Goes into Making and Receiving an FMT?

OpenBiome and our collaborator, the University of Minnesota, follow the steps below to manufacture our FMT preparations.

  1. Donor screening and stool donation: A donor who has passed screening for potential health risks provides a stool sample.
  2. Processing: The stool sample is mixed with a buffer to help bacteria survive being frozen. The resulting mixture is filtered to remove fiber and solid particles that may clog the machinery used to administer the FMT treatment.
  3. Storage and Administration: Newly made FMT treatments are stored frozen in a -80 degree Celsius freezer. Treatments are shipped overnight on dry ice to hospitals where they are once again stored in freezers or thawed and administered to a patient.

Patients, depending on their unique health status and medical history, may receive FMT in three different modalities.

  1. Upper delivery (though a nasoenteric/gastric tube or EGD)
  2. Lower delivery (though colonoscopy, sigmoidoscopy, or enema)
  3. Orally (through a capsule form)

FMT is typically an outpatient procedure, and patients are usually able to return home a few hours after the procedure.

Am I Eligible for an FMT?

It’s important to speak with your doctor about whether FMT is the right option for you. Patients who meet the requirements below may be eligible for an FMT treatment

1. Diagnosis of C. difficile infection (CDI).
a. You have been diagnosed with mild or moderate CDI and have failed to respond to at least two courses of standard-of-care antibiotic therapies.
b. You have been diagnosed with severe/fulminant CDI that has failed standard-of-care antibiotic therapy

2. Informed consent Conversation: You have discussed FMT as a treatment options with your doctor and understand
a. That FMT is an investigational treatment that is not approved by the FDA.
b. The potential risks of FMT as well as alternative treatment options, including to receive no treatment.


Next Steps for Receiving an FMT

If you are eligible for an FMT, the next step is to further discuss the treatment with your doctor.

Once you make a decision together, your doctor will place an order with OpenBiome. Once ordered, it typically takes a few days for an FMT treatment to arrive at the hospital where your procedure will take place.
