The bacterium Clostridioides difficile (C. difficile) forms organelles that help them defend against iron in the colon. According to a group of scientists from Vanderbilt University, this pathogen, which causes serious gastrointestinal infections, expresses fez genes to build structures called ferrosomes that store excess iron that is toxic to it. Its ferrosomes are surrounded by membrane and could be a target against this microorganism.
An experimental antibiotic was able to prevent recurrent Clostridioides difficile infections (rCDI) by killing bacterial spores as well as growing spores. Researchers from the University of Notre Dame reported their findings in the Proceedings of the National Academy of Sciences on May 8, 2023.
The supply chain for Seres Therapeutics Inc.’s oral microbiome therapeutic Vowst, formerly known as SER-109, to prevent recurrent Clostridium difficile infection (rCDI) is “well-established,” said David Arkowitz, the firm’s chief financial officer and head of business development. “It’s the same supply chain that we used for phase III [trials], and we’ve been manufacturing product for launch for some time.” Arkowitz spoke during a conference call with investors April 27, regarding the previous day’s U.S. FDA go-ahead for Vowst, cleared for adults with rCDI, including first recurrence following antibacterial therapy.
As expected, Seres Therapeutics Inc. gained U.S. FDA approval of the BLA for the oral microbiome therapeutic Vowst, formerly known as SER-109, for prevention of recurrent Clostridium difficile infection (rCDI), accepted for priority review in October of 2022 without an advisory committee meeting.
Mbiomics GmbH raised €13 million (US$14.2 million) in a first close of a series A round that will enable it to pivot from being a microbiome analytics firm to becoming a therapeutics developer.
Microbiome company Finch Therapeutics Group Inc. has suffered one blow after another in the past year with dwindling cash, delayed programs, a terminated deal and three workforce reductions. The latest reduction will bring the once healthy 189-person company down to a handful of employees, and it places the lead program – the oral microbiota product, CP-101, for Clostridiumdifficile infection – on the sidelines.
Following Therapeutic Goods Administration approval of its first-generation donor-derived microbiome-based therapy, Biomictra, for recurrent Clostridioides difficile infection, Australia’s Biomebank is scaling up to meet increasing global demand for fecal microbiota products and is developing a more scalable second-generation synthetic product.

The U.S. FDA has approved its first fecal microbiota treatment. Rebyota (fecal microbiota, live-jslm), from privately held Ferring Pharmaceuticals Inc., is now approved to prevent recurring Clostridioides difficile infection (CDI) in adults. The Nov. 30 approval came about two months after the FDA’s Vaccines and Related Biological Products Advisory Committee voted 13-4 to support the microbiome therapy’s effectiveness in reducing recurrent CDI in adults after antibiotic treatment for recurrent CDI.
The race to become the first microbiome-based therapy to reach the market continues between two companies. A positive view by the U.S. FDA’s Vaccines and Related Biological Products Advisory Committee on Sept. 22 for RBX-2660 in preventing recurrent Clostridium difficile infection kept Ferring Pharmaceuticals Inc.’s microbiota-based live biotherapeutic moving forward.
