Response to FDA Safety Alert Regarding the Use of Fecal Microbiota for Transplantation

Parsippany, New Jersey – 14 June 2019 — Rebiotix and Ferring Pharmaceuticals were saddened to learn about the patients mentioned in the FDA’s safety alert regarding the use of Fecal Microbiota for transplantation and risk of serious adverse reactions due to transmission of multi-drug resistant organisms*. We do not have any details regarding the patients mentioned in the safety alert, as they were not enrolled in our clinical trials. Our thoughts are with their families. These unfortunate events reinforce our commitment to bringing safe and effective FDA-approved products to market.

We are aligned with and remain committed to the FDA’s additional protections as outlined in the safety alert. Rebiotix and Ferring are strong proponents of the appropriate screening of donor derived microbiota products as a means to avoid a public health incident, as described in the FDA safety alert. Rebiotix was the first company to engage the FDA in defining a regulatory pathway for microbiota-based therapies. We continue to work closely with the FDA to sponsor high quality clinical trials with stringent donor screening programs, as we conduct our fourth clinical trial on our lead candidate RBX2660.
