Conference call at 8:30 a.m. ET today
CAMBRIDGE, Mass. March 5, 2024 Seres Therapeutics, Inc. (Nasdaq: MCRB), a leading microbiome therapeutics company, today reported fourth
quarter and full year 2023 financial results and provided business updates.
2023 was an historic year for Seres as we launched our first-in-class oral microbiome therapeutic, VOWST, for recurrent CDI into commercialization with our collaborators at Nestl Health Science, said Eric Shaff,
President and Chief Executive Officer of Seres. We are proud of the impact VOWST is having on patients and, as we enter 2024, our top priority remains continuing to deliver VOWST to patients and advancing the potential of microbiome
therapeutics. VOWST is indicated to prevent the recurrence of Clostridioides difficile infection (CDI) in adults following antibacterial treatment for recurrent CDI. We are also excited about obtaining clinical results from the Phase 1b
study with SER-155 and the potential to prevent enteric infections and resulting blood stream infections and GvHD in allo-HSCT patients. These complications are far too frequent, potentially fatal, and costly
to the healthcare system.
Our 2023 results since the launch of VOWST in June, exceeded our expectations across multiple dimensions,
said Terri Young, Ph.D., Chief Commercial and Strategy Officer at Seres. We saw quarterly acceleration in demand in terms of new patient starts and prescription enrollment forms as well as progress on the reimbursement front. In close
collaboration with our colleagues at Nestl Health Science, we will continue our focus on HCP education, customer experience, payer coverage and hospital outflow.
In December, we were excited to announce the Fast Track Designation for SER-155 based on preclinical and cohort
1 data, with the cohort 2 data readout anticipated in the third quarter of 2024, said Mr. Shaff. We believe positive data from this readout would further validate the promise of this novel therapeutic modality in addressing
difficult to tackle infections, including in immunocompromised patients such as those with chronic liver disease, cancer neutropenia, solid organ transplant, and AMR infections more broadly in settings of high-risk such as intensive care units.
These additional opportunities have the potential to extend the value of SER-155 or our pre-clinical stage assets significantly and establish a new standard of care in
protecting immunocompromised patients from life-threatening infections.
VOWST Commercial Performance (Previously announced on January 9, 2024)
Broad demand for VOWST has been observed across rCDI patients and healthcare providers since product launch in June 2023:
2023 and Recent Highlights
Anticipated 2024 Milestones
Seres reported a net loss of $113.7 million for the full year of 2023, as compared to a net loss of $250.2 million for the prior year. Seres reported
a net loss of $41.2 million for the fourth quarter of 2023, as compared to a net loss of $68.8 million for the same period in 2022.
of VOWST for the fourth quarter and full year 2023, were $10.4 million and $19.6 million, respectively based on 673 and 1,284 units of VOWST sold. Following the first commercial sale of VOWST, Seres shares equally with Nestl , its
collaborator, in the VOWST commercial profits and losses. Seres share of the VOWST net loss for the fourth quarter and full year 2023 was $10.3 million and $18.9 million, respectively, which was included in the Company s
operating results within Collaboration (profit) loss sharing related party.
Research and development expenses for the fourth quarter of 2023 were
$26.8 million, compared with $46.2 million for the same period in 2022. The research and development expenses were primarily related to Seres VOWST clinical development program and manufacturing costs, as well as personnel costs. The
year-over-year decrease in R&D expenses is primarily driven by VOWST commercial manufacturing costs no longer being recognized in the Seres P&L following the product approval in April 2023, but instead capitalized and recognized on the
Company s balance sheet.
General and administrative expenses for the fourth quarter of 2023 were $17.2 million, compared with
$22.4 million for the same period in 2022. General and administrative expenses were primarily related to personnel expenses, professional fees, including VOWST commercial readiness and pre-launch expenses
incurred prior to the launch of VOWST in June 2023, and facility costs.
In November 2023, Seres announced a significant corporate restructuring to
substantially reduce expenses and prioritize the commercialization of VOWST. The restructuring, which is expected to achieve approximately $75 million to $85 million in annual cash saving in 2024, was substantially implemented around year-end 2023. As a result, research and development and general and administrative expenses for the fourth quarter of 2023 were minimally impacted by the restructuring. In addition, included within research and
development and general and administrative expenses for the fourth quarter of 2023 were $5.6 million of one-time charges related to the restructuring.
As of December 31, 2023, Seres had
$128.0 million in cash, cash equivalents and marketable securities as compared with $181.3 million at the end of 2022. Seres anticipates that this year-end cash balance, in conjunction with the
planned savings from the restructuring announced in November 2023 and, assuming continued quarter-over-quarter revenue growth of VOWST, the expected receipt of the $45 million Tranche B under its existing senior secured debt facility (the Term
Loan Facility) with Oaktree Capital Management, L.P. (Oaktree), will support its operations into the fourth quarter of 2024.
Seres management will host a conference call today, March 5, 2023, at 8:30 a.m. ET. The conference call may be accessed by
calling 1-800-715-9871 (international callers dial 1-646-307-1963) and reference the conference ID number 4030622. To join the live webcast, please visit the Investors and News section of the Seres website
