WALTHAM, Mass., Aug. 11, 2021 (GLOBE NEWSWIRE) -- Entasis Therapeutics Holdings Inc. (NASDAQ: ETTX), a clinical-stage biopharmaceutical company focused on the discovery and development of novel antibacterial products, announced today financial results for the second quarter 2021 and issued a business update for the quarter and recent weeks.

“During our second quarter and in recent weeks we continued to build upon the momentum in our clinical programs that began earlier in the year. We completed enrollment in the ATTACK Phase 3 registrational trial which is evaluating sulbactam-durlobactam (SUL-DUR) for the treatment of carbapenem-resistant Acinetobacter infections, and continued enrollment in the Phase 3 registrational trial that is evaluating zoliflodacin for the treatment of uncomplicated gonorrhea,” said Manos Perros, President and Chief Executive Officer of Entasis Therapeutics. “As announced recently, we now expect top-line data readout from the ATTACK trial early in the fourth quarter. To further our commercialization planning, we are pleased to welcome Anna Diaz Triola as our new Chief Commercial Officer. Anna brings a track record of commercializing products across multiple therapeutic areas, including antibacterials, and we look forward to her advancing our commercialization capabilities. We are also excited by progress in the rest of our pipeline, specifically our new first-in-class candidate ETX0462, a novel diazabicyclooctane with antimicrobial activity against multiple Gram-negative pathogens including Pseudomonas aeruginosa as well as a number of high-priority biothreat pathogens. With the completion of the second tranche of our $20 million private placement transaction with Innoviva, we now anticipate that our cash runway will be sufficient to fund our operations through the second quarter of 2022. We are pleased with our progress this quarter and continue to work toward transforming Entasis into a commercial stage company.”

Second Quarter 2021 and Recent Highlights
SUL-DUR

• The Company, along with its partner Zai Lab (NASDAQ: ZLAB), announced the completion of patient enrollment in ATTACK, a single Phase 3 registrational trial that is evaluating the safety and efficacy of SUL-DUR in patients with confirmed carbapenem-resistant Acinetobacter infections. Over 120 evaluable patients were enrolled into the primary efficacy arm, sufficient to complete the trial. The Company anticipates top-line data readout early in the fourth quarter.
  
  
• The Company will host an Expert Perspectives on Acinetobacter Infections Webinar, Tuesday, August 24, at 10:00 AM ET. This program will feature presentations by Infectious Disease experts Dr. David van Duin of the University of North Carolina and Dr. Michael J. Rybak of Wayne State University, who will discuss the burden and current treatment landscape of Acinetobacter infections. The program is open to all interested parties, and registration is available here or on our website www.entasistx.com.
  

World Microbe Forum

• Entasis presented 7 posters and one oral presentation highlighting ETX0462, a novel, first-in-class, diazabicyclooctane with antimicrobial activity against multiple Gram-negative pathogens including Pseudomonas aeruginosa as well as a number of high-priority biothreat pathogens. This novel class of agents is designed to potentially target a broad spectrum of multidrug resistant bacterial pathogens that are included in both the Center for Disease Control and World Health Organization lists of high unmet medical need pathogens.  Presentations also included updates on SUL-DUR and ETX0282CPDP, an oral β-lactam/β-lactamase inhibitor being developed to treat multidrug-resistant Gram-negative pathogens, including those caused by extended-spectrum β-lactamases (ESBLs) and carbapenem-resistant Enterobacteriaceae (CRE).
  

Corporate & Business Highlights

• The Company appointed Anna Diaz Triola as its Chief Commercial Officer, effective July 19, 2021. Ms. Triola brings over 20 years of experience in the launch and commercialization of products across multiple therapeutic areas and diverse settings of care, including the hospital and community. She previously served as the Vice President, Marketing at Summit Therapeutics where she was instrumental in developing the commercial strategy for the company’s first product against C. difficile infections. Prior to joining Summit, Ms. Triola held commercial leadership roles at Flexion Therapeutics, Chiasma, Cubist, and Biogen. Ms. Triola holds an M.B.A from Harvard Business School and a B.A. from Wellesley College.
  
  
• The Company completed a private placement to sell Entasis common stock and warrants to a wholly-owned subsidiary of Innoviva Inc. (Nasdaq: INVA), Entasis’ largest shareholder. The gross proceeds to the Company from the transaction totaled $20 million, before deducting offering expenses payable by the Company. The Company intends to use the net proceeds for completing the ATTACK trial, NDA filing preparation, SUL-DUR launch readiness as well as working capital and other general corporate purposes.
  

Second Quarter Financial Results
The Company reported a net loss of $12.0 million for the three months ended June 30, 2021, compared to a net loss of $13.4 million for the three months ended June 30, 2020. The decrease in net loss was primarily related to an increase in grant income during the second quarter of 2021 versus the prior year.

Research and development expenses were $10.0 million during the three months ended June 30, 2021, compared to $10.2 million during the three months ended June 30, 2020. The decrease of $0.2 million was primarily due to a decrease of $1.1 million in expenses related to our SUL-DUR product candidate, attributable to a decrease in clinical trial costs. This decrease was partially offset by an increase in expenses related to our ETX0462 product candidate and personnel expenses associated with higher headcount.

General and administrative expenses were $3.3 million for the three months ended June 30, 2021, compared to $3.2 million during the three months ended June 30, 2020. The increase of $0.1 million was driven primarily by an increase in insurance related costs.

As of June 30, 2021, cash and cash equivalents were $56.4 million, compared to $53.2 million as of December 31, 2020. Based our current operating plan, we believe that our existing cash and cash equivalents, including amounts received from the most recent private offering, will be sufficient to fund our operating expenses and capital expenditure requirements through the second quarter of 2022.
