WATERTOWN, Mass., Feb. 23, 2016 (GLOBE NEWSWIRE) -- Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH), a clinical stage biopharmaceutical company developing novel antibiotics to treat life-threatening multidrug-resistant (MDR) infections, today reported financial results for the fourth quarter and year ended December 31, 2015 and provided a review of corporate milestones for 2016.

"We are focused on continuing to advance the development of eravacycline as we remain confident in its potential to become an important option for patients with serious infections," said Guy Macdonald, Tetraphase's President and Chief Executive Officer.  "We continue to have discussions with the FDA regarding the next steps for IV eravacycline and look forward to providing an update after we have received regulatory guidance, which we still anticipate in the first quarter of 2016."

"In parallel, we are planning to initiate an additional phase 3 clinical trial for once-daily IV eravacycline in complicated urinary tract infections (cUTI) in the third quarter of 2016, the design for which is currently being finalized. We are also continuing the clinical development of an oral dose formulation for eravacycline," Mr. Macdonald added. "Beyond the eravacycline program, we are advancing our pipeline of novel antibiotic candidates.  We will continue our phase 1 clinical program for TP-271 which is being developed to combat respiratory disease caused by bacterial biothreats and antibiotic-resistant public health pathogens. We also plan to initiate a phase 1 clinical trial evaluating TP-6076, our second-generation antibiotic candidate with potent activity against multidrug-resistant Gram-negative pathogens, during the second quarter of 2016.  We look forward to keeping you updated on our progress throughout the year."

  • Initiate IV-only phase 3 clinical trial for eravacycline in cUTI - 3Q 2016

Fourth-Quarter and Full-Year 2015 Financial Results

As of December 31, 2015, Tetraphase had cash and cash equivalents of $205.9 million and 36.6 million shares outstanding.  The company expects that its cash and cash equivalents, as well as expected revenue from its U.S. government awards, will be sufficient to fund operations into at least early 2018.

For the fourth quarter of 2015, Tetraphase reported a net loss of $18.1 million, or $0.50 per share, compared to a net loss of $20.6 million, or $0.69 per share, for the same period in 2014. Revenues were $2.5 million compared to $3.1 million for the same period in 2014. Revenues for each period consisted of contract and grant revenue under the Company's U.S. government awards for the development of Tetraphase compounds for the treatment of diseases caused by bacterial biothreat pathogens and for certain infections caused by life-threatening multidrug-resistant bacteria. Research and development (R&D) expenses for the fourth quarter of 2015 were $15.0 million compared to $19.7 million for the same period in 2014. The decrease in R&D expenses was primarily due to lower clinical trial and drug manufacturing costs for eravacycline as the IGNITE2 clinical trial concluded. General and administrative (G&A) expenses for the fourth quarter of 2015 were $5.6 million compared to $3.7 million for the same period in 2014. The increase in G&A expenses was primarily due to costs to support pre-commercialization activities for eravacycline.

For the year ended December 31, 2015, Tetraphase reported a net loss of $83.2 million, or $2.36 per share, compared to a net loss of $66.7 million, or $2.49 per share, for the same period in 2014. Revenues were $11.7 million for the year ended December 31, 2015 compared to $9.1 million for the same period in 2014. As stated above, revenues for each period consisted of contract and grant revenue under the Company's U.S. government awards for the development of Tetraphase compounds for the treatment of diseases caused by bacterial biothreat pathogens and for certain infections caused by life-threatening multidrug-resistant bacteria. R&D expenses were $73.8 million for the year ended December 31, 2015 compared to $61.9 million for the same period in 2014. The increase in R&D expenses was primarily due to drug manufacturing and nonclinical costs in support of our NDA-related and pre-commercialization activities for eravacycline and activities in support of our preclinical candidate, TP-6076, as well as an increase in stock-based compensation. G&A expenses were $20.9 million for the year ended December 31, 2015 compared to $12.9 million for the same period in 2014. The increase in G&A expenses was primarily due to costs to support pre-commercialization activities for eravacycline.
