CAMBRIDGE, Mass.— August 6, 2024 -- Seres
Therapeutics, Inc. (Nasdaq: MCRB), (“Seres” or the “Company”), a leading live biotherapeutics company, today announced that it signed an agreement
with Société des Produits Nestlé S.A (“Nestlé”) for the sale of its VOWST business to Nestlé Health Science. Upon deal closing, Seres will receive capital infusions, including an upfront payment, a prepaid milestone payment and an equity
investment. In addition, Seres is due to receive installment payments in 2025, as well as potential future payments based on VOWST net sales targets. Seres will support ongoing VOWST availability by providing transition services through the first
quarter of 2025 and manufacturing support through the end of 2025 (subject to limited extension rights by Nestlé) and will continue to share 50/50 in the profit and loss of the business through the end of 2025. The completion of the transaction,
which is subject to Seres’ shareholder approval and other customary conditions, is expected to occur in the next 90 days.
“This transaction provides meaningful capital to support Seres’
pipeline advancement and our focus on improving patient outcomes in medically vulnerable populations through the use of cultivated live biotherapeutics,” said Eric Shaff, President and Chief Executive Officer of Seres. “We are proud of our accomplishments in bringing VOWST to the market as the first ever FDA-approved oral microbiome therapy with an outstanding efficacy and safety profile and now look forward
to applying our approach to transform care in new patient groups. As part of the transaction, a number of our talented colleagues will move to Nestlé Health
Science – we thank these team members for their contributions to Seres and to developing, manufacturing, and launching VOWST. We also would like to acknowledge Nestlé
Health Science as a long-time collaborator and wish them tremendous success as they continue to deliver VOWST to patients and grow the business.”
Mr. Shaff continued, “We will use the capital from this
transaction to strengthen our balance sheet, retire our existing debt facility, and advance our pipeline. Our lead SER-155 program remains on track to provide
clinical results from the placebo-controlled Cohort 2 segment of the ongoing study in patients receiving allogeneic hematopoietic stem cell transplant (allo-HSCT) in September. SER-155 is designed to prevent gastrointestinal (“GI”)-derived infections
and resulting bloodstream infections, as well as induce immune tolerance responses to reduce the incidence of graft-versus-host-disease (GvHD) and, if successful, could profoundly improve patient outcomes. In addition to SER-155, we are developing
other cultivated live biotherapeutic candidates for multiple medically vulnerable patient groups, including potentially those with chronic liver disease, cancer neutropenia, and solid organ transplants. Seres’ therapeutic approach could protect these
patients from life-threatening infections, thereby creating significant commercial opportunities.”
Deal Terms, Use of Proceeds and Cash Runway
Under the terms of the agreement, Seres is due to receive:
|
• |
Payment of $100M, less approximately $20M in settlement of net obligations payable to Nestlé at closing
|
|
• |
Prepayment of a $60M milestone payment at closing
|
|
• |
Installment payments of $50M in January 2025, and $25M (less up to approximately $1.5M in employment related payments to Nestlé), in July 2025,
subject to Seres’ material compliance with transition obligations
|
|
• |
Future milestone payments based on VOWST worldwide net sales as follows:
|
|
o |
$125M upon achievement of annual worldwide net sales of $400M; and
|
|
o |
$150M upon achievement of annual worldwide net sales of $750M
|
In addition, at the closing, Nestlé will purchase $15M of Seres common stock at closing, representing the purchase of 14,285,715 shares, at
a price per share of $1.05 (reflecting a 10% premium to the 30-day volume weighted average price prior to the announcement of the Memorandum of Understanding).
Seres plans to use the capital from this transaction to fully
retire its senior secured debt facility with Oaktree Capital Management and support the further advancement of SER-155 and its other cultivated product candidates.
As various VOWST-related capabilities, including product
manufacturing, will transition to Nestlé, the Company expects to reduce its workforce by more than one-third, streamlining its operations and reducing cash burn following the closing of the deal. Based on Seres' current cash, its future operating plans, the capital expected to be obtained from the transaction, and accounting for on-going deal obligations, the Company anticipates its cash
runway will extend into Q4 2025.
Future Strategy
Moving forward, Seres will pursue a focused corporate strategy where the Company will apply its experience with cultivated live
biotherapeutic candidates, building upon the clinical and regulatory success previously demonstrated with VOWST, to improve patient outcomes in a variety of medically vulnerable populations. Specifically, the Company intends to develop new
therapeutics for populations known to harbor disrupted gastrointestinal microbiomes and/or compromised immune systems, who are at high risk of serious, life-threatening bacterial infections that are costly to healthcare systems.
Seres’ lead program, SER-155, is designed to prevent GI-derived infections and resulting bloodstream infections, as well as induce immune
tolerance responses in order to reduce the incidence of GvHD in patients undergoing allo-HSCT. Patients undergoing allo-HSCT are at a high risk of life-threatening bacterial infections, providing an opportunity to transform how these patients are
managed. SER-155 is currently being evaluated in an ongoing Phase 1b study and the Company anticipates clinical results from a placebo-controlled Cohort 2 group in September.

The SER-155 composition is designed to prevent gastrointestinal (GI)-derived infections and resulting bloodstream infections, enhance epithelial barrier
integrity, and induce immune tolerance responses to reduce the incidence of graft-versus-host-disease (GvHD). SER-155 is being evaluated in a Phase 1b study in patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT). SER-155
is a consortium of bacterial species selected and optimized using Seres’ reverse translation discovery and development platform technologies. The design incorporates biomarker data from human clinical data and nonclinical human cell-based assays, and
in vivo disease models. SER-155 has received FDA Fast Track Designation.

Background on Nestlé Health Science Collaboration and VOWST
In July 2021, Seres entered a license agreement with Nestlé
Health Science that granted a co-exclusive license to develop and commercialize VOWST. In April 2023, VOWST obtained FDA approval to prevent the recurrence of Clostridioides
difficile infection (CDI) in adults following antibacterial treatment for recurrent CDI (rCDI), followed by commercial launch in June 2023 led by
Nestlé Health Science. Under the pending agreement, Nestlé Health Science will obtain full ownership of the VOWST business. Seres will support the full transition of VOWST to Nestlé and the continuity of the supply chain through a customary transition service agreement.
