CAMBRIDGE, Mass.--(BUSINESS WIRE)--Mar. 16, 2017-- Seres Therapeutics Inc., (NASDAQ:MCRB), a leading microbiome therapeutics platform company, today reported fourth quarter and full year 2016 financial results and provided an update on multiple clinical programs, including three clinical-stage candidates seeking to address multiple serious medical indications. In a separate announcement today, Seres provided an update on plans to initiate a new SER-109 clinical study following its positive FDA Type B meeting.

“Seres has made important progress across all of our microbiome clinical programs,” said Roger J. Pomerantz, M.D., President, CEO and Chairman of Seres. “Following the completion of our comprehensive analyses of the SER-109 study results, we had very productive discussions with the FDA, in which we gained highly positive and constructive guidance on further SER-109 clinical development. If the new ECOSPOR III study achieves a persuasive clinical effect and addresses FDA requirements, we would expect to be able to file for SER-109 product registration.”

Dr. Pomerantz continued, “We also advanced our robust pipeline of microbiome clinical candidates and we anticipate the results of two Phase 1b clinical trials during the second half of this year, including our study of SER-287 in patients with ulcerative colitis and our study of SER-262, the first synthetically derived microbiome candidate to reach clinical development, in patients with primary C. difficile infection.”

Recent Highlights and Events

  • Positive SER-109 Type B meeting with FDA and plan for new SER-109 clinical study: Seres plans to initiate a new SER-109 clinical study (ECOSPOR III) in approximately 320 patients with multiply recurrent Clostridium difficile (C. difficile) infection. Study participants will be randomized 1:1 between SER-109 and placebo. Diagnosis of C. difficile infection for both study entry and for endpoint analysis will be confirmed by C. difficile cytotoxin assay. Patients in the SER-109 arm will receive a total SER-109 dose, administered over three days, approximately 10-fold higher than the dose used in the prior ECOSPOR study. ECOSPOR III will evaluate patients for 24 weeks and the primary endpoint will compare the C. difficile recurrence rate in subjects who receive SER-109 versus placebo at up to eight weeks after dosing. The FDA has agreed that this new trial may qualify as a pivotal study with achievement of a persuasive clinical effect and addressing FDA requirements, including clinical and statistical factors, an adequately sized safety database, and certain CMC parameters.
  • Key findings from SER-109 Phase 2 study analyses: Seres announced the results of its in-depth analyses of the previously reported SER-109 Phase 2, eight-week clinical study data in patients with multiply recurrent C. difficile infection.
  • Ongoing progress with SER-287 Phase 1b study: Seres continued to advance the SER-287 Phase 1b clinical study in subjects with mild-to-moderate ulcerative colitis who have failed first line therapy. SER-287 is a biologically sourced Ecobiotic® microbiome therapeutic candidate. Additional SER-287 Phase 1b study clinical sites were activated and increasing numbers of study subjects are being enrolled. Study results are expected in the second half of 2017.
  • Ongoing progress with SER-262 Phase 1b study: Seres continued to advance the SER-262 Phase 1b clinical study in patients with primary C. difficile infection. SER-262, an Ecobiotic®, rationally-designed, fermented microbiome therapeutic candidate, is the first synthetically-derived and designed microbiome therapeutic candidate to reach clinical-stage development. Additional SER-262 Phase 1b study clinical sites were activated and increasing numbers of study subjects are being enrolled. Study results are expected in the second half of 2017.
  • Preclinical microbiome program research: Seres continued to advance its preclinical efforts, working in collaboration with existing world-class academic researchers, including projects targeting hematopoietic stem cell transplantation and immuno-oncology treatment, with Memorial Sloan Kettering Cancer Center; liver diseases including primary sclerosing cholangitis and Non-Alcoholic Steatohepatitis (NASH), with Mayo Clinic; inflammatory bowel disease (IBD) and rare genetic metabolic diseases, with the University of Pennsylvania, Medical University of Graz, Austria and the Research Institute of St. Joseph’s Hamilton; and obesity and metabolic syndrome, with the Massachusetts General Hospital of the Harvard Medical School.
  • Additional microbiome patent issued: Seres continued to strengthen its intellectual property estate related to microbiome therapeutics. The United States Patent and Trademark Office issued a new patent (#9,585,921), assigned to Seres, covering compositions for treating multiple gastrointestinal diseases associated with dysbiosis of the microbiome.
  • Manufacturing facility completed: Seres continued to broaden its differentiated microbiome therapeutic development capabilities. The construction of a new facility capable of the manufacture and formulation of microbiome therapeutic candidates was completed and is now fully operational.

Financial Results

The company reported a net loss of $91.6 million for the full year, as compared to a net loss of $54.8 million for the prior year. Seres reported a net loss of $25.3 million for the fourth quarter of 2016, as compared to a net loss of $19.6 million for the same period in 2015. The increase in fourth quarter net loss was driven primarily by continued growth in clinical and development expenses as well as increased headcount, and ongoing development of the company’s microbiome therapeutics platform. The fourth quarter net loss figure was inclusive of $3.0 million in revenue recognized associated with the company’s collaboration with Nestlé Health Science.

Research and development expenses for the full year of 2016 were $82 million, as compared to $38.1 million for the prior year. R&D expenses for the fourth quarter of 2016 were $20.3 million, as compared to $13.9 million for the same period in 2015. The increase in R&D expense was primarily due to expenses related to the company’s microbiome therapeutics platform, the clinical development of SER-109, SER-262 and SER-287, as well as the company’s preclinical programs.

General and administrative expenses for the full year of 2016 were $32.6 million, as compared to $16.8 million for the prior year. G&A expenses for the fourth quarter of 2016 were $8.5 million, as compared to $5.9 million for the same period in 2015. The increase in G&A expense was primarily due to increased headcount, an increase in professional fees, and facility expansion to support overall growth.

The decrease in cash balance during the quarter was $26.5 million. Seres ended the fourth quarter with approximately $230.0 million in cash, cash equivalents and investments.

Financial Expectations

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 future business development activities, through 2018.
