About a year ago, when Seres Therapeutics Inc. won U.S. FDA approval of oral microbiome therapy Vowst (live fecal microbiota spores), the drug – meant to prevent recurrent Clostridioides difficile infection – was hailed as first in the space, and launch plans sounded ambitious. In July 2021, Seres inked a deal with Nestlé Health Science SA, of Lutry, Switzerland, to jointly commercialize Vowst in the U.S. and potentially Canada. But shares of Cambridge, Mass.-based Seres (NASDAQ:MCRB) closed May 8 at 75 cents, down 36 cents, or 32%, after the firm provided an update on sales, roughly flat quarter over quarter.
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.
