CAMBRIDGE, Mass.--(BUSINESS WIRE)--Feb. 25, 2016-- Seres Therapeutics Inc. (NASDAQ: MCRB), a leading microbiome therapeutics platform company, today reported financial results and provided a business update for the fourth quarter and full year ended December 31, 2015.

The company highlighted the progress it made in advancing its commercial strategy and expanding its pipeline into new indications.

“The fourth quarter 2015 and early 2016 has been a period of unprecedented growth for Seres in which we made tremendous progress in preparing for the expected commercialization of our therapies for Clostridium Difficile (CDI) infection, while also expanding into new therapeutic areas with our Ecobiotic® microbiome therapeutics platform,” said Roger Pomerantz, M.D., President, CEO and Chairman of Seres. “Our strategic agreement with Nestlé Health Science for our CDI and Inflammatory Bowel Disease (IBD) product candidates provides global reach outside of the US and Canada and further strengthens our financial position. In parallel, the initiation of our Phase 1b SER-287 study in ulcerative colitis (UC) marks the first time a microbiome therapeutic candidate has been tested in a chronic disease. In 2016 we anticipate several important milestones, including SER-109 Phase 2 results in recurrent CDI infection in mid-2016, the initiation of a Ph1b study for SER-262, a fermented synthetically derived therapeutic candidate, in primary recurrent CDI in mid-2016, and the initiation of a Phase 3 study for SER-109 in recurrent CDI infection in the second half of 2016.”

Fourth Quarter and Recent Business Highlights:

Financial Results and Guidance:

The company reported a net loss of $54.8 million for the full year, as compared to a net loss of $18.0 million for the prior year. The company reported a net loss of $19.6 million for the fourth quarter, as compared to a net loss of $8.5 million for the fourth quarter of 2014. The increase in net loss was driven by clinical and development spending related to SER-109 and SER-287, continued growth in headcount, and ongoing development of our microbiome therapeutics platform, as well as increased facilities costs. The fourth quarter net loss included stock-based compensation expense of $2.8 million as compared to $1.4 million in the same period of the prior year.

Research and development expenses for the full year of 2015 were $38.1 million, as compared to $10.7 million for the prior year. Research and development expenses for the fourth quarter were $13.9 million, as compared to $5.1 million for the same period in the prior year. R&D expenses for the fourth quarter included stock-based compensation expense of $1.5 million, as compared to $0.7 million for the same period in the prior year.

General and administrative expenses for the full year were $16.8 million, as compared to $4.4 million for the prior year. General and administrative expenses for the fourth quarter were $5.9 million, as compared to $2.2 million for the same period in the prior year. The increase in G&A expense was due primarily to continued investment in business personnel and facility expansion to support overall growth, as well as increased professional fees, including those associated with the Nestle Health Science transaction, and costs associated with operating as a public company. G&A expenses for the quarter included stock-based compensation expense of $1.3 million, as compared to $0.6 million for the same period in the prior year.

Seres ended the third quarter of 2015 with $219.3 million in cash, cash equivalents and investments and ended the fourth quarter with $205.1 million in cash, cash equivalents and investments which does not include the $120 million upfront payment received from Nestlé Health Science in February 2016.

During the fourth quarter of 2015, Seres signed an agreement to lease a facility that will house its corporate headquarters, including laboratories, office space, and a pilot manufacturing facility. The pilot facility will broaden capabilities in bioprocess development and synthetic microbiome candidate manufacturing. The company expects that build-out and equipment investment related to the facility will require approximately $20 million of additional cash outlay during the first three quarters of 2016. Capital expenditures during the full year of 2015 totaled $7.2 million including $3.5 million incurred during the fourth quarter to support increased lab activities and expand internal manufacturing capabilities.

Based on the company’s current operating plan, Seres expects that its existing cash resources will enable it to fund operating expenses and capital expenditure requirements, excluding cash inflows or outflows from business development activities, well into 2018.
