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-resistantAcinetobacterinfections, 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 ofEntasis 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 includingPseudomonas aeruginosa as well as a number of high-priority biothreat pathogens. With the completion of the second tranche of our$20 millionprivate 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.

-- 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 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 -lactam/-lactamase inhibitor being developed to treat multidrug-resistant Gram-negative pathogens, including those caused by extended-spectrum -lactamases (ESBLs) and carbapenem-resistantEnterobacteriaceae(CRE).

Second Quarter Financial ResultsThe Company reported a net loss of$12.0 millionfor the three months endedJune 30, 2021, compared to a net loss of$13.4 millionfor the three months endedJune 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 millionduring the three months endedJune 30, 2021, compared to$10.2 millionduring the three months endedJune 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 millionfor the three months endedJune 30, 2021, compared to$3.2 millionduring the three months endedJune 30, 2020. The increase of $0.1 million was driven primarily by an increase in insurance related costs.

As ofJune 30, 2021, cash and cash equivalents were$56.4 million, compared to$53.2 millionas ofDecember 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.
