Ferring to Present New Data Analyses at ACG 2023 for REBYOTA® (fecal microbiota, live – jslm), the First and Only Single-Dose, FDA Approved Microbiome-Based Treatment for the Prevention of Recurrent C. difficile Infection



PARSIPPANY, N.J.--(BUSINESS WIRE)-- Ferring Pharmaceuticals today announced it will present two analyses of data for REBYOTA® (fecal microbiota, live – jslm), the first and only single-dose, FDA approved microbiome-based treatment to prevent recurrent Clostridioides difficile (C. diff) infection after antibiotic treatment. The data will be presented as part of the American College of Gastroenterology’s (ACG) 2023 Annual Scientific Meeting, being held October 20 – 25 in Vancouver, Canada.

One analysis to be presented at ACG will evaluate the association between the gut microbiome and health-related quality of life (HRQL) in adults with recurrent C. diff infection. The other presentation is an ad hoc analysis from an open-label Phase 3 study on the efficacy and safety of REBYOTA in recurrent C. diff infection patients who are 65 years of age or older and living with other illnesses, such as chronic kidney disease, cardiac disease or gastrointestinal disorders.

Descriptions of the abstracts accepted for presentation are as follows:

About C. diff infection
C. diff infection is a serious and potentially deadly infection that impacts people across the globe. The C. diff 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 C. diff infection can be the start of a vicious cycle of recurrence, causing a significant burden for patients and the healthcare system.2,3 It has been estimated that up to 35% of C. diff infection cases recur after initial diagnosis and people who have had a recurrence are at significantly higher risk of further infections.4,5,6,7 After the first recurrence, it has been estimated that up to 65% of patients may develop a subsequent recurrence.6,7 Antibiotics – the current standard of care for treatment of C. diff infection – treat the disease but can also be a contributing factor to the cycle of recurrence.1

REBYOTA is a pre-packaged, single-dose 150 mL microbiota suspension for rectal administration consisting of a liquid mix of up to trillions of live microbes – including Bacteroides. REBYOTA is delivered directly to the gut microbiome and is administered by a healthcare professional in one visit.

REBYOTA (fecal microbiota, live – jslm) is indicated for the prevention of recurrence of Clostridioides difficile (C. diff) infection in individuals 18 years of age and older, following antibiotic treatment for recurrent C. diff infection.

Limitation of Use
REBYOTA is not indicated for the treatment of C. diff infection.


  • You should not receive REBYOTA if you have a history of a severe allergic reaction (e.g., anaphylaxis) to REBYOTA or any of its components.
  • You should report to your doctor any infection you think you may have acquired after administration.
  • REBYOTA may contain food allergens.
  • Most common side effects may include stomach pain (8.9%), diarrhea (7.2%), bloating (3.9%), gas (3.3%), and nausea (3.3%).
  • REBYOTA has not been studied in patients below 18 years of age.
  • Clinical studies did not determine if adults 65 years of age and older responded differently than younger adults.

You are encouraged to report negative side effects of prescription drugs to FDA. Visit www.FDA.gov/medwatch or call 1-800-332-1088.
