Tetraphase Pharmaceuticals Reports Third Quarter 2016 Financial Results And Reviews Recent Progress

WATERTOWN, Mass., Nov. 03, 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 third quarter ended September 30, 2016, and highlighted recent clinical development achievements in antibiotics pipeline.

"The third quarter was one of meaningful progress for Tetraphase and our phase 3 eravacycline program," said Guy Macdonald, Tetraphase's President and Chief Executive Officer.  "We successfully initiated IGNITE4 evaluating twice-daily intravenous (IV) eravacycline in patients with complicated intra-abdominal infections (cIAI) and announced dosing of the first patient in October.  Top-line results from IGNITE4 are expected as early as the fourth quarter of 2017.  We also continue to prepare for the initiation of IGNITE3, our planned phase 3 trial exploring once-daily IV eravacycline in complicated urinary tract infections (cUTI)."

Mr. Macdonald continued, "For our other antibiotic pipeline candidates, we continue phase 1 development of TP-271, which is being developed for respiratory disease caused by antibiotic-resistant public health pathogens, and TP-6076, our second-generation candidate targeting multidrug-resistant Gram-negative bacterial infections.  Following completion of the single-ascending dose trials this year, we plan to present data at scientific meetings and initiate multiple-ascending dose studies in 2017."

Third Quarter 2016 Financial Results

As of September 30, 2016, Tetraphase had cash and cash equivalents of $162.1 million and 36.7 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 the second half of 2018.

Revenues during the third quarter of 2016 were $0.9 million compared to $2.9 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 third quarter of 2016.

Research and development (R&D) expenses for the third quarter of 2016 ($17.2 million) were similar to the same period in 2015 ($17.0 million), which is reflective of spending patterns related to our phase 3 clinical program for eravacycline.

General and administrative (G&A) expenses for the third quarter of 2016 were $4.9 million compared to $3.9 million for the same period in 2015.  This increase was primarily due to a higher stock-based compensation expense and an increase in legal fees, offset by a decrease in pre-commercialization activities.

For the third quarter of 2016, Tetraphase reported a net loss of $21.1 million, or $0.58 per share, compared to a net loss of $18.0 million, or $0.49 per share, for the same period in 2015.  The net loss for the three and nine months ended September 30, 2016 includes stock-based compensation expense of $3.3 million and $10.3 million, respectively.

Third Quarter and Recent Corporate Highlights
  • Presented data at IDWeek 2016, including in vitro data for eravacycline demonstrating consistent and potent in vitro 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.
  • Initiated the phase 3 IGNITE4 clinical trial of IV eravacycline in cIAI.  Assuming a successful outcome, this study, along with data from IGNITE1, will support an NDA filing for IV eravacycline for cIAI.  IGNITE4, compared to meropenem in patients with cIAI, is expected to enroll approximately 450 patients and the primary analysis will be conducted using a 12.5% non-inferiority margin.  Tetraphase expects to have top-line results in the fourth quarter of 2017.
  • Initiated patient dosing in a single-ascending dose phase 1 clinical trial evaluating the safety and pharmacokinetics of TP-6076 in healthy volunteers. TP-6076 is being developed for the treatment of serious and life-threatening bacterial infections, including those caused by pathogens otherwise resistant to current treatment options.
  • 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.
