“The gut microbiome is a highly diverse community of microbes that plays an essential role in human health. Emerging research has shown the promise of leveraging the microbiome to address a range of conditions, including serious diseases such as recurrent C. difficile infection,” said Elizabeth Garner, Chief Scientific Officer, Ferring Pharmaceuticals, U.S. “The cycle of recurrent CDI represents a significant public health burden, and Ferring is working to address that unmet need.”

The FDA intends to live stream the advisory committee meeting on the agency's YouTube page, and the meeting will also be webcast from the FDA website.

About C. difficile infection
C. difficile infection (CDI) is a serious and potentially deadly disease that impacts people across the globe. The C. difficile bacterium causes debilitating symptoms such as severe diarrhea, fever, stomach tenderness or pain, loss of appetite, nausea, and colitis (an inflammation of the colon).¹ Declared a public health threat by the U.S. Centers for Disease Control and Prevention (CDC) requiring urgent and immediate action, CDI causes an estimated half a million illnesses and tens of thousands of deaths in the U.S. alone each year.^1,2,3

C. difficile infection can be the start of a vicious cycle of recurrence, causing a significant burden for patients and the healthcare system.^4,5 It has been estimated that up to 35% of CDI cases recur after initial diagnosis and people who have had a recurrence are at significantly higher risk of further infections.^6,7,8,9 After the first recurrence, it has been estimated that up to 65% of patients may develop a subsequent recurrence.^8,9
