“With the launch of REBYOTA, Ferring is proud to offer an urgently needed new treatment option for adults suffering from the burden of recurrent C. diff infection,” said Brent Ragans, President, Ferring Pharmaceuticals U.S.

REBYOTA was approved by the U.S. FDA on November 30, 2022. The efficacy and safety of REBYOTA was studied in the largest clinical trial program in the field of microbiome-based therapeutics, including five clinical trials with more than 1,000 participants. REBYOTA is a single-dose treatment that is administered in minutes during one visit at the doctor’s office.

“The availability of REBYOTA is great news for people who are suffering from the devastating cycle of recurrent C. diff infection,” said Paul Feuerstadt, M.D., F.A.C.G., A.G.A.F., Yale University School of Medicine. “Healthcare providers can now offer an FDA-approved microbiome treatment and provide patients with new hope to help fight this infection.”

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 for a vicious cycle of recurrence, causing a significant burden for patients suffering from this debilitating and potentially deadly illness.^1,8

About REBYOTA

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. Each dose of REBYOTA is delivered directly to the gut microbiome.

The FDA approval of REBYOTA was based on results from the randomized, double-blind, placebo-controlled Phase 3 PUNCH™ CD3 trial in which a single dose of REBYOTA demonstrated superiority to placebo as a treatment to reduce recurrent C. diff infection after standard-of-care antibiotic treatment. Two hundred sixty-two (262) trial participants received blinded treatment (n=177, REBYOTA; n=85, placebo) and the primary endpoint was treatment success, defined as the absence of C. diff infection diarrhea for eight weeks after completing study treatment. The Bayesian model-estimated treatment success rate at eight weeks for REBYOTA was 70.6% versus 57.5% for placebo, with a 99.1% posterior probability that REBYOTA was superior to placebo in reducing recurrent C. diff infection after standard-of-care antibiotic treatment.⁹ More than 90% of study participants who achieved treatment success remained free of recurrent C. diff infection through six months.¹⁰

In the study, adverse events (AEs) were primarily mild-to-moderate and there were no treatment-related serious adverse events (SAEs). Incidence of treatment-emergent adverse events (TEAEs) was higher in REBYOTA recipients compared with placebo (55.6%, n=100/180, REBYOTA; 44.8%, n=39/87, placebo), mostly driven by a higher incidence of mild gastrointestinal events.¹⁰

INDICATION

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.
