XERAVA^TM (eravacycline) Now Available to Hospitals in the United States

Conference Call Today at 4:30 p.m. Eastern Time

WATERTOWN, Mass., Nov. 08, 2018 (GLOBE NEWSWIRE) -- Tetraphase Pharmaceuticals, Inc. (NASDAQ:TTPH), a biopharmaceutical company focused on developing and commercializing novel antibiotics to treat life-threatening multidrug-resistant (MDR) infections, today reported financial results for the quarter ended September 30, 2018 and provided a corporate update.

“During the third quarter of 2018, we reached our most significant milestones as a company to date – the regulatory approvals of XERAVA for the treatment of complicated intra-abdominal infections (cIAI) in both the U.S. and Europe, followed by the commercial launch of XERAVA in the U.S. in October. We are thrilled to have accomplished these extraordinary achievements and to have made this important new antibiotic treatment available to patients in need. XERAVA is now available for use in hospitals and healthcare institutions for the treatment of a range of patients with empiric and confirmed cIAI infections,” said Chief Executive Officer, Guy Macdonald.

Mr. Macdonald added, “We are also pleased to have entered into a loan agreement for up to $75 million, the first $30 million tranche of which extends our cash runway into the second quarter of 2020 and provides us with additional flexibility to support a strong launch of XERAVA in the U.S. Beyond XERAVA, we look forward to milestones for our earlier-stage programs, including completion of our Phase 1 multiple ascending-dose study for oral TP-271, in development to target respiratory infections, and initiation of a bronchopulmonary disposition study for TP-6076, targeted against Acinetobacter baumannii and other MDR pathogens. As a commercial company with a focus on delivering XERAVA to patients in need, we are also continuing our pipeline efforts to develop additional antibiotic options to fight MDR infections.”

Key Upcoming Milestones

• Commence Phase 1 bronchopulmonary disposition study for TP-6076 – 1Q 2019
• Complete Phase 1 multiple ascending-dose study for oral TP-271 – 2Q 2019 
• Begin phased launch of XERAVA in Europe – 1H 2019

Third Quarter and Recent Highlights

• AnnouncedCommercial Launch of XERAVA for cIAI Following the U.S. Food and Drug Administration (FDA) Approval in August
  The Company commercially launched XERAVA in the U.S. in October 2018. XERAVA is now available for use in hospitals and healthcare institutions for the treatment of a range of patients with empiric and confirmed cIAI infections. The salesforce will be focusing on institutions responsible for treating patients in 90% of the Gram-negative marketplace.
  
  XERAVA’s launch followed FDA approval of XERAVA in August for the treatment of cIAI in patients 18 years of age and older. Supporting XERAVA’s approval were results from two Phase 3 clinical studies that showed the therapy was well-tolerated and achieved high clinical cure rates in patients with cIAI, thus demonstrating statistical non-inferiority to two widely used carbapenems – ertapenem and meropenem.
  
  
• Received Marketing Authorization from the European Commission (EC) for XERAVA in the European Union (EU)
  In September, the EC adopted the July 2018 positive opinion issued by the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) to grant marketing authorization for XERAVA for the treatment of cIAI in adults in all EU member states as well as Iceland, Liechtenstein and Norway. Following this approval, the Company is on track for a phased European launch of XERAVA, beginning with Germany and the UK in the first half of 2019.
  
  
• Presented XERAVA and TP-6076 Data at the Infectious Disease Society of America’s (IDSA) 2018 IDWeek
  In October, the Company presented data related to XERAVA and TP-6076 at IDSA’s IDWeek. Among the data presented were results from a post-hoc analysis of XERAVA Phase 3 data, which showed high clinical cure rates and microbiological eradication with XERAVA among patients with cIAI and concurrent bacteremia. Data from a Phase 1 randomized, placebo-controlled, double-blind, multiple-ascending-dose study demonstrating positive safety, tolerability and pharmacokinetic results for the Company’s novel, fully synthetic tetracycline, TP-6076 were also presented.
  
  
• Presented XERAVA Data at the American College of Clinical Pharmacy (ACCP) 2018 Global Conference
  In October, the Company announced positive data from a post-hoc analysis of two Phase 3 trials of XERAVA in higher risk populations – obese patients and those with altered renal function. Similar clinical cure rates were observed for XERAVA across all classifications of renal function, further supporting that the drug is an effective empiric treatment for cIAI comparable to carbapenems which may provide an alternative to antibiotics that require dosing modification in patients with altered renal function. XERAVA was also effective in treating patients with cIAI regardless of body mass index when dosed 1mg/kg IV every 12 hours, based on total body weight when compared to carbapenems.
  
  
• Entered into Loan and Security Agreement with Solar Capital Limited
  In November 2018, the Company entered into a loan agreement with Solar Capital Limited providing us up to $75 million with $30 million funded at closing, to be used to support the commercial launch of XERAVA and general corporate purposes. Armentum Partners acted as advisor to the Company on the transaction.

Third Quarter 2018 Financial Results
As of September 30, 2018, Tetraphase’s cash and cash equivalents were $97 million, and there were approximately 53.5 million shares outstanding. The Company expects that its cash and cash equivalents, including the initial funding of $30 million from the debt facility, as well as expected revenue from its U.S. government awards and commercial sales of XERAVA in the U.S. and Europe, will be sufficient to fund operations into the second quarter of 2020.

Revenues during the third quarter of 2018 were $1.2 million compared to $4.1 million for the same period in 2017. Revenues for each period consisted of contract and grant revenue under the Company's U.S. government awards for the development of Tetraphase compounds. The decrease was primarily due to the timing of activities under these awards.

Research and development (R&D) expenses for the third quarter of 2018 were $11.7 million compared to $28.8 million for the same period in 2017. The decrease in R&D expenses was primarily due to the completion of the IGNITE Phase 3 clinical studies for XERAVA.

Sales, general and administrative expenses for the third quarter of 2018 were $9.5 million compared to $5.6 million for the same period in 2017. This increase was primarily due to commercialization expenses to support the U.S. launch of XERAVA.

For the third quarter of 2018, Tetraphase reported a net loss of $19.6 million, or a loss of $0.37 per share, compared to a net loss of $30.0 million, or a loss of $0.63 per share, for the same period in 2017.

About XERAVA^TM

XERAVA (eravacycline) for injection is a tetracycline class antibacterial indicated for the treatment of complicated intra-abdominal infections (cIAI) in patients 18 years of age and older. It is approved for use in the U.S. and Europe. XERAVA was investigated for the treatment of cIAI as part of the Company's IGNITE (Investigating Gram-Negative Infections Treated with Eravacycline) Phase 3 program. In the first pivotal Phase 3 trial in patients with cIAI, twice-daily intravenous (IV) eravacycline met the primary endpoint by demonstrating statistical non-inferiority of clinical response compared to ertapenem and was well-tolerated. In the second Phase 3 clinical trial in patients with cIAI, twice-daily IV eravacycline met the primary endpoint by demonstrating statistical non-inferiority of clinical response compared to meropenem and was well-tolerated. In both trials, XERAVA achieved high cure rates in patients with Gram-negative pathogens, including resistant isolates.

XERAVA^TM Important Safety Information

XERAVA is a tetracycline class antibacterial indicated for the treatment of complicated intra‑abdominal infections in patients 18 years of age and older.

XERAVA is not indicated for the treatment of complicated urinary tract infections.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of XERAVA and other antibacterial drugs, XERAVA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

XERAVA is contraindicated for use in patients with known hypersensitivity to eravacycline or to tetracycline-class antibacterial drugs. Life-threatening hypersensitivity (anaphylactic) reactions have been reported with XERAVA.

The use of XERAVA during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown) and enamel hypoplasia.

The use of XERAVA during the second and third trimester of pregnancy, infancy and childhood up to the age of 8 years may cause reversible inhibition of bone growth.

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis.

The most common adverse reactions observed in clinical trials (incidence ≥ 3%) were infusion site reactions, nausea, and vomiting.

XERAVA is structurally similar to tetracycline-class antibacterial drugs and may have similar adverse reactions. Adverse reactions including photosensitivity, pseudotumor cerebri, and anti‑anabolic action which has led to increased blood urea nitrogen, azotemia, acidosis, hyperphosphatemia, pancreatitis, and abnormal liver function tests, have been reported for other tetracycline-class antibacterial drugs, and may occur with XERAVA. Discontinue XERAVA if any of these adverse reactions are suspected.

To report SUSPECTED ADVERSE REACTIONS, contact Tetraphase Pharmaceuticals Inc., at 1-833- 7-XERAVA (1-833-793-7282) or FDA at 1‑800‑FDA-1088 or www.fda.gov/medwatch.
