– Company to Host Conference Call Today, March 8, 2017 at 4:30 p.m. ET –

WATERTOWN, Mass., March 08, 2017 (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, 2016, highlighted key milestones for 2017 and provided an overview of recent achievements.

“2016 marked a year of important progress for Tetraphase as we advanced our phase 3 global development program for IV eravacycline with initiation of IGNITE4 in complicated intra-abdominal infections (cIAI), in which enrollment is proceeding well, and the recent commencement of IGNITE3 in complicated urinary tract infections (cUTI),” said Guy Macdonald, President and Chief Executive Officer of Tetraphase. “We have laid the groundwork for an event-driven 2017 and look forward to several important IV eravacycline milestones, including the submission of a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for the treatment of cIAI during the second half of the year and top-line data from IGNITE4 during the fourth quarter, which would support a subsequent NDA filing.”

Mr. Macdonald continued, “Beyond IV eravacycline, we are also focused on completing the phase 1 clinical development of oral eravacycline and expect to provide an update during the third quarter of 2017, including next steps toward our goal of delivering the first and only IV-to-oral antibiotic transition therapy for the treatment of MDR gram-negative infections.”

Key Milestones for 2017

  • Submit MAA for IV eravacycline to EMA for the treatment of cIAI – 2H 2017
  • Report top-line data from phase 3 IGNITE4 trial evaluating IV eravacycline in cIAI – 4Q 2017
  • Provide oral eravacycline development program update – 3Q 2017
  • Report phase 1 single-ascending dose data for TP-271 – mid-2017
  • Report phase 1 single-ascending dose data for TP-6076 – mid-2017
  • Initiate phase 1 multiple-ascending dose trials for IV TP-271 and IV TP-6076 – 2017

Fourth Quarter and Recent Highlights

  • Initiated the phase 3 IGNITE4 clinical trial of IV eravacycline in patients with cIAI. IGNITE4 is designed to evaluate IV eravacycline compared to meropenem and is expected to enroll approximately 450 patients. The primary analysis will be conducted using a 12.5% non-inferiority margin. Tetraphase expects to report top-line results in the fourth quarter of 2017. Assuming a successful outcome, this study, along with data from IGNITE1, would support an NDA filing for IV eravacycline for cIAI.

  • Initiated the phase 3 IGNITE3 clinical trial of IV eravacycline in patients with cUTI. IGNITE3 is designed to evaluate IV eravacycline compared to ertapenem and is expected to enroll approximately 1,000 patients. The primary analysis will be conducted using a 10% non-inferiority margin. Assuming a positive outcome, the IGNITE3 clinical data are expected to support a supplemental New Drug Application (sNDA) submission for IV eravacycline in cUTI.

  • Published results from IGNITE1 in the Journal of the American Medical Association (JAMA) Surgery. In the phase 3 IGNITE1 trial, eravacycline was well tolerated and demonstrated statistical non-inferiority to ertapenem in patients with cIAI.

  • Presented data at IDWeek 2016, including in vitro data for eravacycline demonstrating consistent and potent activity against drug-resistant bacteria, including carbapenem-resistant Enterobacteriaceae (CRE), Acinetobacter baumannii, vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA), isolated from recent patients.

  • Published data in Antimicrobial Agents and Chemotherapy (AAC) demonstrating that eravacycline retained potency against E. coli clinical isolates containing a plasmid expressing mcr-1 (ERV MIC90=0.5 µg/mL; colistin MIC90=16 µg/mL).

  • Continued clinical testing designed to advance the development of an oral dose formulation of eravacycline. Additional clinical testing is ongoing to evaluate variables associated with increasing drug exposure and optimizing the oral eravacycline dosing regimen.

  • Continued to advance pipeline candidates, TP-271 and TP-6076, with the completion of phase 1 single-ascending dose studies for the IV formulations of both compounds.

  • Received Qualified Infectious Disease Product and Fast Track designation from the FDA for the oral formulation of TP-271 and initiated a single-ascending dose phase 1 study of oral TP-271.

  • Promoted Larry Edwards to Chief Commercial Officer in January 2017. Larry joined Tetraphase as Vice President, Marketing in 2015 and this promotion recognizes Larry’s contributions in providing strong leadership and direction in the commercial and business development functions. Larry has exceptional commercialization experience for early and late-stage hospital infectious disease products. Prior to Tetraphase, he served as Senior Director of Marketing, Gram Negative Franchise for Cubist Pharmaceuticals from April 2014 through the Merck acquisition, and previously at Merck & Company in infectious disease global marketing leadership roles from 2007 to 2014 and various sales positions of increasing responsibility from 1999 to 2007. Larry has a Masters of Business Administration from St. Joseph's University and a Bachelors of Science in Business & Healthcare Administration from Ohio University.

Fourth-Quarter and Full-Year 2016 Financial Results

As of December 31, 2016, Tetraphase had cash and cash equivalents of $142.1 million and 36.9 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 the second half of 2018.

For the fourth quarter of 2016, Tetraphase reported a net loss of $22.5 million, or $0.61 per share, compared to a net loss of $18.1 million, or $0.50 per share, for the same period in 2015. Revenues were $1.1 million compared to $2.5 million for the same period in 2015. 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. The decrease in revenues was primarily due to the scope and timing of activities related to our BARDA Contract conducted during the fourth quarter of 2016. Research and development (R&D) expenses for the fourth quarter of 2016 were $19.3 million compared to $15.0 million for the same period in 2015. The increase in R&D expenses was primarily due to higher clinical trial costs for eravacycline driven by the start-up activities of our IGNITE3 and IGNITE4 clinical trials, and an increase in manufacturing activity. General and administrative (G&A) expenses for the fourth quarter of 2016 were $4.3 million compared to $5.6 million for the same period in 2015. The decrease in G&A expenses was primarily due to lower headcount-related costs.

For the year ended December 31, 2016, Tetraphase reported a net loss of $77.5 million, or $2.11 per share, compared to a net loss of $83.2 million, or $2.36 per share, for the same period in 2015. Revenues were $5.1 million for the year ended December 31, 2016 compared to $11.7 million for the same period in 2015. 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. The decrease in revenues was primarily due to the scope and timing of activities related to our BARDA Contract conducted during 2016. R&D expenses were $63.8 million for the year ended December 31, 2016 compared to $73.8 million for the same period in 2015. The decrease in R&D expenses was primarily due to a net decrease in development spending on the eravacycline program. G&A expenses were $19.2 million for the year ended December 31, 2016 compared to $20.9 million for the same period in 2015. The decrease in G&A expenses was primarily due to lower spending related to pre-commercialization activities for eravacycline.
