Tetraphase Reports Fourth-Quarter and Full-Year 2013 Financial Results

Tetraphase Reports Fourth-Quarter and Full-Year 2013 Financial Results

March 6, 2014

WATERTOWN, Mass.--(BUSINESS WIRE)--March 06, 2014-- Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH) today reported financial results for the quarter and full year ended December 31, 2013.

"Our first year as a public company has been a productive one for Tetraphase as we advanced our lead antibiotic candidate, eravacycline, into Phase 3 development and confirmed that we will be pursuing two therapeutic indications for regulatory approval," said Guy Macdonald, Tetraphase President and Chief Executive Officer. "Notably, through our initial public offering and subsequent follow-on offering, we raised approximately $130 million, funding that we believe will support the company through our planned eravacycline regulatory filing in the U.S. by the end of 2015."

Mr. Macdonald added: "Eravacycline is the only antibiotic candidate being studied in both IV and oral formulations for the treatment of multi-drug resistant Gram-negative infections in late-stage clinical trials. Given the increasingly favorable regulatory and legislative environments, and the growing recognition of the rising unmet medical need in the Gram-negative antibiotic space by the scientific, pharmaceutical, investment and media communities, we believe we are well positioned to achieve our near-term corporate objectives. We look forward to reporting on our continued progress throughout the year."

Fourth-Quarter and Full-Year 2013 Financial Results

As of December 31, 2013, Tetraphase had cash and cash equivalents of $102.7 million and 25.6 million shares outstanding.

For the fourth quarter of 2013, Tetraphase reported a net loss of $11.3 million, or $0.49 per share, compared to a net loss of $3.1 million, or $9.43 per share, for the same period in 2012. For the full-year 2013, Tetraphase reported a net loss of $29.6 million, or $1.78 per share, compared to a net loss of $15.1 million or $47.54 per share for the full-year 2012.

Revenues for the fourth quarter of 2013 were $1.9 million compared to $3.2 million for the same period in 2012. Revenues for the full-year 2013 were $10.5 million compared to $7.6 million for the full-year 2012. Revenues for each period consisted of contract and grant revenue under three U.S. government awards for the development of Tetraphase compounds as potential countermeasures for the treatment of diseases caused by bacterial biothreat pathogens. These funds are received through subcontracts and a subaward from CUBRC Inc., an independent, not-for-profit research corporation that specializes in U.S. government-based contracts. These U.S. government awards consist of an award from the Biomedical Advanced Research and Development Authority (BARDA) for eravacycline development and two awards from the National Institute of Allergy and Infectious Diseases (NIAID) for the development of the company's preclinical compound TP-271. The decrease in revenue during the fourth quarter of 2013 compared to the same period in 2012 and the increase during the full-year 2013 compared to the same period in 2012 were primarily due to the timing and scope of activities conducted during the periods under our subcontracts under the BARDA contract.

Research and development (R&D) expenses for the fourth quarter of 2013 were $10.5 million, compared to $4.8 million for the same period in 2012. R&D expenses for the full-year 2013 were $31.5 million compared to $17.3 million for the full-year 2012. The increase in R&D expense during both the fourth quarter of 2013 and full-year 2013 compared to the same periods in the prior year was primarily due to an increase in expenses related to clinical and drug manufacturing costs associated with our ongoing Phase 3 program for eravacycline.

General and administrative (G&A) expenses for the fourth quarter of 2013 were $2.3 million, compared to $1.2 million for the same period in 2012. G&A expenses for the full-year 2013 were $7.2 million compared to $4.3 million for the full-year 2012. This increase in G&A expense during both the fourth quarter of 2013 and full-year 2013 compared to the same periods in the prior year was primarily due to an increase in various general costs due to operating as a public company, as well as an increase in personnel-related costs.

2013 and Recent Corporate Highlights

Eravacycline

   -- Presented data from a Phase 2 study supporting the potential efficacy of 
      eravacycline intravenous (IV) in patients with complicated 
      intra-abdominal infections (cIAI) and a Phase 1 study supporting the 
      potential of eravacycline to treat pneumonia at the 23rd European 
      Congress of Clinical Microbiology and Infectious Disease (ECCMID) and 
      IDWeek, respectively. 
 
   -- Branded the global Phase 3 eravacycline program as IGNITE (Investigating 
      Gram-negative Infections Treated with Eravacycline). 
 
   -- Dosed first patient in IGNITE 1 global Phase 3 clinical trial of 
      eravacycline IV in cIAI; top-line data are expected in the first quarter 
      of 2015. 
 
   -- Confirmed the design of IGNITE 2, the two-part Phase 3 study of 
      eravacycline in patients with complicated urinary tract infections (cUTI) 
      that will include both IV and oral formulations of eravacycline 
 
   -- Initiated and are currently screening patients in the IGNITE 2 global 
      Phase 3 clinical trial of eravacycline in cUTI; data from the lead-in 
      portion of IGNITE 2 are expected in mid-2014; top-line data from the 
      pivotal portion of the study are expected in mid-2015. 
 
   -- Received notification from the U.S. Food and Drug Administration (FDA) 
      that eravacycline had been designated a Qualified Infectious Disease 
      Product (QIDP) for the cIAI and cUTI indications; this designation makes 
      eravacycline eligible to benefit from certain incentives for the 
      development of new antibiotics including priority review, and to receive 
      fast-track status and an additional five-years of U.S. market 
      exclusivity.

      candidates and have selected one candidate from this group to advance 
      into pre-IND studies during the second half of 2014.
