WATERTOWN, Mass., Aug. 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 second quarter ended June 30, 2017 and provided an overview of recent achievements.

"Following the recently reported positive phase 3 data from the IGNITE4 clinical trial, we now have two successfully completed phase 3 clinical trials evaluating IV eravacycline in complicated intra-abdominal infections (cIAI).  We remain focused on the execution of many significant upcoming milestones for the company, including a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) this quarter and a New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA) in the first quarter of 2018 for IV eravacycline in cIAI," said Guy Macdonald, President and Chief Executive Officer of Tetraphase. "We are pleased to see enrollment progressing well in the phase 3 IGNITE3 study in complicated urinary tract infections (cUTI), and we look forward to completing enrollment in that study early in the fourth quarter of 2017. If successful, the IGNITE3 data will support a future supplemental NDA filing for once-daily IV eravacycline in cUTI."

"In late July, we strengthened the balance sheet through a public offering of common stock, the gross proceeds of which are $65 million and which will allow us to prepare for the commercial launch of eravacycline. Finally, our phase 1 clinical programs continue to advance. We plan to provide an update to our oral eravacycline development program later this quarter, and we anticipate completion of multiple-ascending dose studies for TP-271 and TP-6076 this year," Mr. Macdonald concluded.

Second 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 intravenous (IV) eravacycline compared to meropenem for the treatment of patients with complicated intra-abdominal infections (cIAI).  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.
  • Presented data at ASM Microbe 2017 including additional supportive data generated for eravacycline demonstrating consistent potency against drug-resistant bacteria in ongoing global surveillance studies and positive data from phase 1 single-ascending dose studies for its two pipeline programs, TP-6076 and TP-271.
  • Successfully completed a public offering of 10,000,000 shares of common stock with gross proceeds totaling $65 million.

Second Quarter 2017 Financial ResultsAs of June 30, 2017, Tetraphase had cash and cash equivalents of $118.2 million and 40.0 million shares outstanding.  The company expects that its cash and cash equivalents, proceeds from the July public offering, as well as expected revenue from its U.S. government awards, will be sufficient to fund operations into early 2019.

Revenues during the second quarter of 2017 were $1.6 million compared to $1.2 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.

Research and development (R&D) expenses for the second quarter of 2017 were $28.5 million compared to $13.7 million for the same period in 2016. The increase in R&D expenses was primarily due to conduct of our IGNITE3 and IGNITE4 phase 3 clinical trials.

General and administrative (G&A) expenses for the second quarter of 2017 were $5.1 million compared to $4.8 million for the same period in 2016.

For the second quarter of 2017, Tetraphase reported a net loss of $31.8 million, or $0.83 per share, compared to a net loss of $17.2 million, or $0.47 per share, for the same period in 2016.
