WATERTOWN, Mass., Nov. 02, 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 third quarter ended September 30, 2017 and provided an overview of recent achievements.

"During the third quarter, Tetraphase achieved several key milestones that continue to set the stage for the potential approval and commercialization of intravenous (IV) eravacycline in 2018," said Guy Macdonald, President and Chief Executive Officer of Tetraphase. "We submitted a Marketing Authorization Application (MAA) for IV eravacycline in complicated intra-abdominal infections (cIAI) to the European Medicines Agency (EMA) which is now under review, and we successfully completed our phase 3 IGNITE4 clinical trial, which, together with IGNITE1, will form the basis of our New Drug Application (NDA) to the FDA in the first quarter of 2018."

Mr. Macdonald continued, "For IV eravacycline in complicated urinary tract infections (cUTI), we completed enrollment in the phase 3 IGNITE3 trial, and expect top-line data to be available in the first quarter of 2018. Assuming a positive IGNITE3 outcome and upon approval of IV eravacycline in cIAI, we plan to file a supplemental NDA (sNDA) for cUTI."

"Lastly, we recently announced an update on our oral eravacycline development program, including positive phase 1 results in healthy volunteers, and look forward to moving our optimized IV-to-oral regimen into a phase 2 clinical trial in cUTI patients in the first half of 2018," Mr. Macdonald added. "With a strengthened balance sheet following a successful public offering in the third quarter, we will be able to execute on these important objectives for the eravacycline program and through our anticipated commercial launch."

Key 2018 Milestones
  • Submit NDA for IV eravacycline for the treatment of cIAI (1Q)
  • Report top-line phase 3 IGNITE3 data for IV eravacycline in cUTI (1Q)
  • Initiate phase 2 clinical trial in cUTI patients for IV-to-oral eravacycline (1H)
  • Complete phase 1 multiple-ascending dose studies for TP-271 and TP-6076 (1H)
  • Potential approval of IV eravacycline for cIAI in US and Europe (2H)
  • Submit sNDA for IV eravacycline in cUTI (2H)

Third Quarter and Recent Highlights
  • Announced positive top-line results from IGNITE4, the Company's phase 3 clinical trial evaluating the efficacy and safety of twice-daily IV eravacycline compared to meropenem for the treatment of patients with complicated intra-abdominal infections.  The results of IGNITE4, which enrolled 500 patients, demonstrated statistical non-inferiority of eravacycline to meropenem for the primary efficacy endpoint of clinical response at the test-of-cure (TOC) visit.
  • Announced that the MAA for IV eravacycline for the treatment of complicated intra-abdominal infections was submitted to and subsequently validated by the EMA.  The MAA filing is based on data from the phase 3 IGNITE1 clinical trial in which eravacycline was well tolerated and demonstrated statistical non-inferiority to ertapenem using the primary endpoint of clinical response at the TOC visit.
  • Announced completion of enrollment in IGNITE3, the Company's ongoing phase 3 clinical trial evaluating the efficacy and safety of once-daily IV eravacycline compared to ertapenem in cUTI.  The Company expects to report top-line data from this trial in the first quarter of 2018.
  • Presented data at IDWeek 2017 from the first study of the Company's recently completed phase 1 program designed to evaluate drug exposure of oral eravacycline in an IV-to-oral dosing regimen. These results, along with data from subsequent trials in this phase 1 program, have allowed for the identification of an optimized IV-to-oral dosing regimen using the current oral eravacycline formulation which the company plans to advance into a phase 2 clinical trial in patients with complicated urinary tract infections. This study is anticipated to begin in the first half of 2018.
  • Successfully completed a public offering of shares of common stock with gross proceeds totaling approximately $65.7 million.
  • Appointed Kamalam (Kam) Unninayar as Chief Financial Officer.  Kam is an experienced financial executive with a track record of over two decades of financial leadership in the life sciences and consumer goods industries. Most recently, Kam spent over 11 years overseeing finance organizations at Thermo Fisher Scientific, a global leader in serving science.

Third Quarter 2017 Financial ResultsAs of September 30, 2017, Tetraphase had cash and cash equivalents of $161.4 million and 51.2 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 2019.

Revenues during the third quarter of 2017 were $4.1 million compared to $0.9 million for the same period in 2016.  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. This increase was primarily due to the scope and timing of activities related to our government contracts conducted during the third quarter of 2017.

Research and development (R&D) expenses for the third quarter of 2017 were $28.8 million compared to $17.2 million for the same period in 2016.  The increase in R&D expenses was primarily due to conduct of our IGNITE3 phase 3 clinical trial.

General and administrative (G&A) expenses for the third quarter of 2017 were $5.6 million compared to $4.9 million for the same period in 2016.  This increase was primarily due to an increase in legal and headcount related costs.

For the third quarter of 2017, Tetraphase reported a net loss of $30.0 million, or $0.63 per share, compared to a net loss of $21.1 million, or $0.58 per share, for the same period in 2016.
