MTC Versus FMT in for RCDI

Официальное название

Comparison of MTC01 vs FMT for the Treatment of Recurrent Clostridioides Difficile Infection

Обзор

Investigating four different treatment of MTC or FMT

Подробное описание

The purpose of this research study is to compare two different treatments for patients with recurrent Clostridiodies difficile infections: MTC01 vs fecal microbiota transplantation (FMT). FMT is the transfer of bacteria from a healthy donor's colon to a recipient's colon. To do this, stool from a healthy donor is blended with salt water and made into a liquid solution rich in bacteria. This solution is sprayed into the recipient's colon during a colonoscopy. This treatment is now considered standard medical care for recurrent Clostridioides difficile infections.

One FMT dose contains the entire collection of microbes in a healthy donor and is made up of billions of microbes. Each dose of FMT is different from the next and it is unknown exactly what microbes are present in each dose.

• Subjects with a qualifying recurrent CDI episode, defined as:

• History of diarrhea (>=3 unformed stools per day for 2 or more consecutive days that is clinically consistent with CDI
• Documented positive stool test by local laboratory for toxigenic C. difficile (toxin EIA or PCR-based testing) for the current CDI episode within 60 days prior to randomization.

• Life expectancy < 6 months
• Unable to adhere to protocol requirements
• Patient who have received an FMT in the past year
• Any condition that the physician investigators deems unsafe, including other conditions or medications that the investigator determines that it will put the subject at greater risk from FMT
