Tetraphase Pharmaceuticals Reports Third-Quarter 2015 Financial Results

WATERTOWN, Mass., Nov. 2, 2015 (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 quarter ended September 30, 2015.

"Despite the recent setback with the results of the IGNITE2 clinical trial in complicated urinary tract infections, we believe that we have a body of clinical and preclinical data supporting eravacycline as a potential antibiotic treatment option for patients with serious infections, particularly those caused by difficult-to-treat Gram-negative bacteria," said Guy Macdonald, Tetraphase's President and Chief Executive Officer. "We look forward to discussions with the regulatory agencies on our path forward and providing an update after we have received regulatory guidance, which we anticipate by the end of this year."

Third-Quarter 2015 Financial Results

As of September 30, 2015, Tetraphase had cash and cash equivalents of $222.5 million and 36.5 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 first half of 2017.

Revenues during the third quarter of 2015 were $2.9 million compared to $2.3 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. This increase was primarily due to the scope and timing of activities related to our BARDA Contract conducted during the quarter ended September 30, 2015.

Research and development (R&D) expenses for the third quarter of 2015 were $17.0 million compared to $13.2 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.

General and administrative (G&A) expenses for the third quarter of 2015 were $3.9 million compared to $3.1 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 third quarter of 2015, Tetraphase reported a net loss of $18.0 million, or $0.49 per share, compared to a net loss of $14.2 million, or $0.55 per share, for the same period in 2014.

Recent Developments

Announced Top-Line Results from IGNITE2 Phase 3 Trial of Eravacycline in cUTI – In September 2015, the Company announced that the IGNITE2 phase 3 clinical trial of eravacycline administered as an IV-to-oral transition therapy for the treatment of complicated urinary tract infections (cUTI) did not meet the primary endpoint of statistical non-inferiority compared to levofloxacin. The Company plans to provide an update after it has discussed the data and a path forward with the regulatory agencies.

FDA Grants QIDP Designation and Fast Track Status to TP-271 – In September 2015, the Company announced that the U.S. Food and Drug Administration (FDA) has granted Qualified Infectious Disease Product (QIDP) and Fast Track designations for the intravenous formulation of TP-271, the Company's novel, broad spectrum antibiotic candidate which is being developed to combat respiratory disease caused by bacterial biothreats and antibiotic-resistant public health pathogens.

Presented Antibiotics Pipeline Data at ICAAC and IDWeek – In October 2015, the Company presented two posters at IDWeek 2015 describing eravacycline's activity against bacterial pathogens that cause serious infections, including multidrug-resistant Gram-negative bacteria, and the susceptibility of recent anaerobic isolates to eravacycline and comparators.

In September 2015 at ICAAC/ICC 2015, the Company gave 11 data presentations which featured eravacycline and TP-271. Data for eravacycline included clinical data supporting its efficacy in patients at risk for poor outcomes from the phase 3 IGNITE1 clinical trial in complicated intra-abdominal infections, as well as in vitro surveillance data demonstrating its broad-spectrum activity against Gram-negative, Gram-positive and anaerobic bacteria. The preclinical data presented for TP-271 demonstrated good efficacy in mouse models of inhalation anthrax, showing its potential as a post-exposure prophylaxis or treatment against this bacterial biothreat.
