While the emergence of immune checkpoint inhibitor (ICI) therapy in recent years has significantly improved cancer outcomes, some patients have been unable to experience the full therapeutic benefits of ICIs due to significant gastrointestinal inflammation linked to treatment. Seres Therapeutics Inc. is looking to change that with its live biotherapeutic candidate, SER-155, offering impressive findings from phase I data in ICI-related enterocolitis, or irEC.
The BioWorld Infectious Disease Index (BIDI) has continued to decline in the first four months of 2024, finishing April with a year-to-date decrease of 25.12%. BIDI trailed both the Nasdaq Biotechnology Index, which saw a 4.76% downturn by April’s end, and the Dow Jones Industrial Average, which closed the month with a 0.34% increase for the year. In 2023, BIDI ended the year with a 43.48% decline, preceded by an 83.57% drop in 2022.
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.
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.
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.
Unveiling further positive data for SER-109 in preventing recurrent Clostridium difficile infection at Digestive Disease Week (DDW) over the weekend, Seres Therapeutics Inc. reiterated plans to file a BLA with the U.S. FDA in mid-2022. Should the FDA accept the application and grant priority review – SER-109 has breakthrough and orphan status – the medicine could be the first microbiome-based therapy to reach the market.
LONDON – Microbiome specialist Enterobiotix Ltd. closed a $21.5 million series A to advance development of its live bacteria fecal transplant drug pipeline.
