SAINT-PREX, SWITZERLAND & PARSIPPANY, N.J.-- September 23, 2022 -- Ferring Pharmaceuticals today announced that the Vaccines and Related Biological Products Advisory Committee (VRBPAC) of the U.S. Food and Drug Administration (FDA) issued a positive vote for RBX2660, an investigational microbiota-based live biotherapeutic studied for its potential to reduce recurrence of C. difficile infection (CDI) after antibiotic treatment.

VRBPAC voted 13 to 4 that the data were adequate to support the effectiveness of RBX2660 to reduce the recurrence of CDI in adults 18 years of age and older following antibiotic treatment for recurrent CDI. The Committee also voted 12 to 4 with 1 abstention that the data were adequate to support the safety of RBX2660 when administered to adults 18 years of age and older following antibiotic treatment for recurrent CDI. The advisory committee provides recommendations to the FDA, which the agency may consider but is not required to follow, when making its decision.

“Patients with recurrent C. difficile infection currently have limited treatment options,” said Paul Feuerstadt, MD, FACG, AGAF, Yale University School of Medicine. “The committee’s vote is a step toward potentially addressing the debilitating cycle of recurrence and the suffering faced by these patients.”

The committee reviewed data from the biologics license application (BLA) for RBX2660. The clinical development program for RBX2660 included six studies with a total of 1061 participants, of which 978 were treated with RBX2660.

“Today’s advisory committee vote represents an important milestone in Ferring’s ongoing efforts to address the unmet need for interventions that can reduce the incidence of recurrent C. difficile infection, which represents a significant health burden for patients,” said Mirjam Mol-Arts, Executive Vice President, Chief Medical Officer, Ferring Pharmaceuticals.
