Ferring to Present Award-Winning, Landmark Research for Investigational Microbiota-Based Live Biotherapeutic RBX2660 at IDWeek 2021

• Analysis of data from five RBX2660 prospective studies is one of only four abstracts to receive the coveted IDWeek 2021 Program Committee Choice award for outstanding scientific research.
• Ferring and Rebiotix will present new data showing an association between clinical outcomes and restoration of the microbiome
• Research from the Phase 3 PUNCH CD3 trial on the effects of RBX2660 on deadly antimicrobial resistance genes and the restoration of bile acid composition, also will be presented.

(BUSINESS WIRE)-- Ferring Pharmaceuticals and Rebiotix, a Ferring Company, today announced they will present data from the clinical development program for RBX2660, an investigational microbiota-based live biotherapeutic for reduction of recurrent Clostridioides difficile (C. difficile) infection, as part of IDWeek 2021. The congress will take place virtually from September 29 – October 3, 2021.

Notably, the data include the first-time presentation of an analysis from five prospective clinical studies, which represent the totality of this comprehensive body of clinical evidence for a microbiota-based live biotherapeutic. IDWeek acknowledged this presentation and its author, Lindy L. Bancke, PharmD, Head of Clinical Development at Rebiotix, as one of only four recipients of the 2021 Program Committee Choice award, based on outstanding scientific research.

Additionally, the company will present data demonstrating the association of RBX2660 in gut microbiome restoration and the impact of the decolonization of deadly multi-drug resistant organisms.

“Our data presentations at IDWeek will not only add to the growing body of clinical evidence supporting RBX2660, but they bring together nearly a decade of research that show exciting advancements in how RBX2660 clinical outcomes relate to microbiome composition,” said James P Tursi, M.D., Chief Scientific Officer, Ferring Pharmaceuticals U.S.

The clinical development program for RBX2660 is the largest and most robust ever conducted in the field of microbiome-based therapeutics for recurrent C. diff infection, enrolling more than 1,000 patients to date and including two studies that followed patients for 24 months.

About the gut microbiome and 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 often is the start of a vicious cycle of recurrence, causing a significant burden for patients and the healthcare system.^4,5 Up to 35% of CDI cases recur after initial diagnosis^6,7 and people who have had a recurrence are at significantly higher risk of further infections.^8,9,10,11 After the first recurrence, it has been estimated that up to 60% of patients may develop a subsequent recurrence.¹²

Recurrent C. difficile infection (rCDI) is associated with disruptions to the gut microbiome, or “dysbiosis”. The gut microbiome is a highly-diverse microbial community that plays an essential role in human health. There is a growing body of evidence that shows when there is a disruption of the composition and/or diversity of the gut microbiome, there may be an associated risk for serious illnesses, including CDI. The current standard of care treatment for rCDI is antibiotics, which does not address the underlying dysbiosis or restore the gut microbiome.¹³ The use of antibiotics has been shown to disrupt the ecology of the gut microbiome and are a predominant risk factor for rCDI.^6,7,13

Restoring the gut microbiome is increasingly accepted as a promising treatment option for recurrent C. difficile infection.¹⁴
