Nestlé Health Science agrees to acquire global rights to VOWST®, product it launched in June 2023

Transaction ensures Nestlé Health Science will continue to commercialize the product

Seres Therapeutics, Inc. (Nasdaq: MCRB), announced today that it has agreed to a non-binding memorandum of understanding with Nestlé Health Science in which Nestlé Health Science will acquire certain tangible and intangible assets associated with VOWST (fecal microbiota spores, live-brpk) capsules.  This transaction, when completed, supersedes any prior agreements between Nestlé and Seres concerning VOWST. Nestlé Health Science has been the lead commercialization party for the product since its launch in June 2023 in the United States.  This transaction will allow Nestlé Health Science full control over the further development, commercialization, and manufacturing of VOWST in the US and worldwide.

“VOWST has been extremely successful since we first made it available to patients in June of last year,” said Moreno Perugini, President of Medical Nutrition and Pharma, Nestlé Health Science.  “We have had a productive collaboration with Seres during the development and FDA approval of VOWST, and we are pleased to continue to provide this important medication to patients.”

VOWST is the first and only U.S. Food and Drug Administration (FDA)-approved orally administered microbiota-based therapeutic to prevent recurrence of Clostridioides difficile infection (CDI) in adults following antibacterial treatment for recurrent CDI (rCDI).

VOWST is not indicated for the treatment of CDI. Please see the full Indication, Limitation of Use, and Important Safety Information below.

Perugini continued, “With the Nestlé Health Science portfolio focused on nutritional science, our pharma business specializes on medical conditions that are specifically related to gastrointestinal disorders. VOWST fits within our expertise and fills a significant unmet need in the market; we are confident that sales will continue to grow and that many more patients will benefit from it.”

The transaction is subject to the negotiation of definitive agreements, Seres shareholder approval and other customary conditions.


VOWST (fecal microbiota spores, live-brpk) is indicated to prevent the recurrence of Clostridioides difficile infection (CDI) in individuals 18 years of age and older following antibacterial treatment for recurrent CDI.

Limitation of Use: VOWST is not indicated for treatment of CDI.

Potential presence of food allergens: VOWST may contain food allergens. The potential to cause adverse reactions due to food allergens is unknown.


The most common adverse reactions (reported in ≥5% of participants) were abdominal distension (31.1%), fatigue (22.2%), constipation (14.4%), chills (11.1%), and diarrhea (10.0%).
