Seres Therapeutics Reports Third Quarter 2015 Financial Results and Provides Business Update

FDA granted Orphan Drug Designation for SER-109 in recurrent C. difficile infection (CDI)

CAMBRIDGE, Mass.--()--Seres Therapeutics Inc. (NASDAQ: MCRB), a leading microbiome therapeutics platform company, today reported financial results and provided a business update for the third quarter ended September 30, 2015.

“Over the past few months, we have continued to make significant progress in the microbiome space by advancing our promising pipeline of Ecobiotic® therapeutics,” said Roger Pomerantz, M.D., President, CEO and Chairman of Seres. “We received Orphan Drug Designation for SER-109, our first-in-field treatment candidate for recurrent C. difficile infection, or CDI, which is currently moving forward in a Phase 2 study. We were particularly honored by this decision by the FDA, since orphan status is rarely given to an infectious disease therapeutic.

“We also have accomplished meaningful development progress in SER-262, our drug candidate to prevent the primary recurrence of CDI infection, and we intend to have this in the clinic in mid-2016, as the first synthetic microbiome investigational therapy. In addition, we expect to bring SER-287 in ulcerative colitis to the clinic by the end of this year. SER-287 will be the first microbiome therapeutic candidate to be studied for treatment of a chronic disease. These recent advances in key programs show our commitment to the mission of delivering Ecobiotic® medicines to patients in dire need, and demonstrate well our leadership in this new field in biomedicine.”

Third Quarter and Recent Business Highlights:

  • SER-109 granted Orphan Drug Designation by the FDA, facilitating the development process through advantages, including an extended seven-year period of market exclusivity upon approval, tax credits for clinical research expenses incurred in the United States, and an exemption from FDA application user fees. In addition, SER-109 was granted Breakthrough Designation by the FDA in June 2015.
  • Continued to advance pipeline of Ecobiotic® candidates, including the ongoing Phase 2 clinical trial of SER-109 in recurrent CDI with data expected in mid-2016; completion of IND-enabling preclinical studies for SER-287 for treatment of ulcerative colitis, with a Phase 1b study expected to begin by the end of 2015; and important bioprocess advancement supporting SER-262 for treatment of primary C. difficile infection (CDI) recurrence, with clinical studies anticipated to begin in mid-2016.
  • Advanced research and translational science functions n developing microbiome agents to prevent bacterial infections and graft versus host disease (GVHD) in human stem cell transplant patients (SER-155). Research is also underway on microbiome drugs to address certain rare genetic diseases and to treat colitis induced by immuno-oncology therapies.
  • Closing of Seres’ initial public offering, including receipt of approximately $139 million of proceeds, inclusive of the full exercise of underwriter’s option and net of underwriting discounts and offering expenses.
  • Appointed Kurt Graves to Board of Directors. Mr. Graves is currently the Chairman, President and CEO of Intarcia Therapeutics.

Third Quarter Financial Results:

For the third quarter of 2015, Seres reported a net loss of $(14.6) million, or $(0.38) per share, compared to a net loss of $(4.6) million, or $(0.68) per share for the same period in 2014.

  • Research and Development: R&D expenses for the third quarter of 2015 were $9.9 million, compared to $2.5 million for the same period in 2014. The increase was largely due to expenditures in connection with Seres’ microbiome therapeutic platform and clinical development of SER-109.
  • General and Administrative Expenses: G&A expenses for the third quarter of 2015 were $4.7 million, compared with $1.1 million for the same period in 2014. The increase was primarily due to Seres’ continued investment in business personnel, facility expansion to support the company’s overall growth, and increased professional fees and other costs associated with operating as a public company.
  • Cash Position: Seres had cash, cash equivalents and investments of $219.3 million as of September 30, 2015, compared to $91.8 million as of June 30, 2015.

Financial Guidance:

Based on the company’s current operating plan, Seres expects that cash, cash equivalents and investments as of September 30, 2015, will enable it to fund operating expenses and capital expenditure requirements, excluding cash inflows or outflows from business development activities, through the first half of 2017.
