CAMBRIDGE, Mass. May 8, 2024 Seres Therapeutics, Inc. (Nasdaq: MCRB), a leading microbiome therapeutics company, today reported
first quarter 2024 financial results and provided business updates.
With a broad indication and compelling clinical profile to prevent the
recurrence of Clostridioides difficile infection (CDI) in adults following antibacterial treatment for recurrent CDI (rCDI), VOWST enables healthcare providers to fundamentally transform how they treat this life-threatening disease.
Along with our collaborators at Nestl Health Science, we have continued to make progress with the launch of VOWST. Nestl continues to refine its launch execution, and we have seen a resulting acceleration of VOWST sales during March
and April, said Eric Shaff, President and Chief Executive Officer of Seres.
Additionally, we completed enrollment of Cohort 2 in our ongoing SER-155 Phase 1b study and look forward to sharing a comprehensive topline dataset during the third quarter. These clinical results could further validate the vast potential of microbiome therapeutics in preventing
adverse outcomes linked to gastrointestinal pathogens, continued Mr. Shaff. Our goal remains to leverage Seres industry-leading microbiome capabilities to advance the development of
SER-155 and other product candidates in additional indications such as chronic liver disease, cancer neutropenia, and solid organ transplants, which could protect millions of medically vulnerable patients from
life-threatening infections. In support of this objective, we are evaluating various options to provide the Company with additional capital and to advance our pipeline.
