Seres Therapeutics Reports Fourth Quarter and Full Year Financial Results and
Provides Operational Updates
- Initiated SER-287 Phase 2b study in
mild-to-moderate ulcerative colitis -
- Initiated SER-401 Phase 1b study in metastatic melanoma -
- Conference call at 8:30 a.m. ET today -
CAMBRIDGE, Mass., March 6, 2019 Seres Therapeutics, Inc. (Nasdaq: MCRB) today reported fourth quarter and full year 2018 financial
results and provided an operational update.
This has been a highly eventful period where we advanced our microbiome clinical programs and
implemented a more focused R&D strategy. During the last several months, we initiated two clinical studies and implemented corporate changes to concentrate resources on the highest priority programs, said Eric Shaff, President and Chief
Executive Officer of Seres Therapeutics. Seres is working to expeditiously progress our ongoing clinical studies to data read outs while also advancing our next generation, rationally-designed, fermented microbiome drug discovery capabilities
centered on SER-301 for ulcerative colitis. We expect to complete SER-287 Phase 2b study enrollment by mid-2020 and obtain SER-401 Phase 1b study results in 2020. We continue to evaluate design options around our SER-109 Phase 3 study in order to expedite trial results.
Seres also announced today the initiation of a SER-401 Phase 1b study in patients with metastatic melanoma. SER-401 is an oral microbiome therapeutic candidate sourced from healthy individuals identified to have a microbiome bacterial signature similar to that observed in immunotherapy responders. The Phase 1b study,
conducted in collaboration with The University of Texas MD Anderson Cancer Center and the Parker Institute for Cancer Immunotherapy, will evaluate the potential for SER-401 to augment response to anti-PD-1 checkpoint inhibitor therapy. The study is designed to enroll 30 patients, who will receive the FDA-approved anti-PD-1 inhibitor nivolumab and will be randomized 2:1 to receive either SER-401 or placebo. The study will evaluate safety, impact
on the gastrointestinal microbiome and various clinical and immunological outcome measures.
Recent Highlights and Events
a net loss of $98.9 million for the full year 2018, as compared to a net loss of $89.4 million for the prior year. Seres reported a net loss of $21.3 million for the fourth quarter of 2018, as compared to a net loss of
$29.0 million for the same period in 2017. The fourth quarter net loss was driven primarily by clinical and development expenses, personnel expenses and ongoing development of the Company s microbiome therapeutics platform. The fourth
quarter net loss figure was inclusive of $10.6 million in recognized revenue associated primarily with the Company s collaboration with Nestl Health Science.
Research and development expenses for the fourth quarter 2018 were $24.8 million, as compared to $24.0 million for the same period
in 2017. The research and development expense was primarily related to Seres microbiome therapeutics platform, the clinical development of SER-109 and SER-287, as
well as the Company s immuno-oncology efforts.
General and administrative expenses for the fourth quarter were $7.5 million, as
compared to $8.8 million for the same period in the prior year. General and administrative expenses were primarily due to headcount, professional fees and facility costs.
The increase in the Company s cash, cash equivalents and investments balance during the quarter was $12.9 million. Seres ended
the fourth quarter with approximately $85.8 million in cash, cash equivalents and investments. The increase in cash in Q4 was inclusive of $40.0 million in milestones received under the Company s collaboration with Nestl
Health Science. Based on the Company s current operating plan, cash resources are expected to fund operating expenses and capital expenditure requirements, excluding net cash flows from future business development activities or potential
incoming milestone payments, into the fourth quarter of this year.
