SOUTH SAN FRANCISCO, Calif., Nov. 08, 2017 (GLOBE NEWSWIRE) --  Achaogen, Inc. (NASDAQ:AKAO), a late-stage biopharmaceutical company discovering and developing innovative antibacterials addressing multi-drug resistant (MDR) gram-negative infections, today reported financial results for the third quarter 2017, and provided an update on its corporate and clinical development activities.

"Submission of the plazomicin NDA was our top priority for 2017 and we are pleased to have completed this milestone towards potentially making plazomicin available for patients. For plazomicin in 2018, our focus will be on achieving commercial readiness for its potential launch in the U.S., and submitting the Marketing Authorization Application (MAA) in the European Union,” said Kenneth Hillan, M.B. Ch.B., Achaogen's Chief Executive Officer. “With C-Scape, our orally-administered antibacterial candidate, we expect top line results from the ongoing Phase 1 clinical trial by the end of this year and to initiate Phase 3 in 2018.”

Recent Highlights and Upcoming Milestones

Plazomicin has successfully completed two Phase 3 clinical trials and the Company has submitted a New Drug Application (NDA) to the Food and Drug Administration (FDA). Achaogen plans to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in 2018. The EPIC (Evaluating Plazomicin In cUTI) trial is expected to serve as a single Phase 3 trial supporting an NDA for plazomicin in the United States and an MAA in the European Union. The second study, the Phase 3 CARE (Combating Antibiotic Resistant Enterobacteriaceae) trial, was a resistant pathogen trial designed to evaluate the efficacy and safety of plazomicin in patients with serious bacterial infections due to carbapenem-resistant Enterobacteriaceae (CRE) and provides additional data supporting the NDA and plazomicin therapy in these patients.

• Submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for plazomicin to treat complicated urinary tract infections (cUTI), including pyelonephritis and bloodstream infections (BSI) due to certain Enterobacteriaceae in patients who have limited or no alternative treatment options;
• Deployed the field-based Medical Affairs team;
• Finalized sales force sizing and structure, and began building out the sales management team; and
• Presented data at IDWeek 2017 highlighting the potential of plazomicin against MDR gram-negative bacteria in clinical and non-clinical settings. Five abstracts were accepted, including presentations of the Phase 3 EPIC and CARE clinical trials.

C-Scape is an orally-available antibacterial candidate that is a combination of an approved beta-lactam and an approved beta-lactamase inhibitor, with the potential to treat patients with cUTI due to MDR pathogens such as extended spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae.

• Awarded a BARDA contract with committed funding of $12 million over nine months and subsequent option periods that could bring the total value of the award to $18 million in non-dilutive funding to support clinical development of C-Scape.

Other Corporate Announcements

• Added Liz Bhatt as Chief Business Officer to the executive management team; and
• Discontinued LpxC inhibitor program research and development efforts.

Third Quarter 2017 Financial Results

Unrestricted cash, cash equivalents and short-term investments totaled $199.4 million at September 30, 2017 compared to $145.9 million at December 31, 2016.

Contract revenue totaled $0.6 million for the third quarter of 2017 compared to $16.0 million for the same period of 2016. The decrease in contract revenue during the quarter was primarily due to lower BARDA contract revenues. As of September 30, 2017, $12.0 million remains on the BARDA C-Scape contract. Achaogen derived all of its revenue from funding provided under Gates Foundation and U.S. government contracts in connection with the research and development of product candidates.

Research and Development (R&D) expenses were $25.3 million for the third quarter of 2017 compared to $20.5 million reported for the same period in 2016. The increase in R&D expenses during the quarter were attributable to increased investment in C-Scape and other early research programs, offset by decreases in the plazomicin program, and an increase in personnel and facilities related costs.

General and Administrative (G&A) expenses were $11.8 million for the third quarter of 2017 compared to $4.5 million for the same period in 2016. The increase in G&A expenses during the quarter was primarily attributable to the increased personnel and professional service related costs as we expand our operations and corporate footprint in preparation for plazomicin launch.

Change in warrant and derivative liabilities was $6.8 million gain for the third quarter of 2017 compared to $1.5 million loss for the same period in 2016. The increase was primarily related to non-cash gain for the revaluation of warrants issued in the private placement of common stock and warrants to purchase common stock in June 2016.

Net loss for the third quarter of 2017 was $29.9 million, compared to a net loss of $11.0 million for the third quarter of 2016. Diluted net loss per share was $0.85 for the third quarter of 2017, compared to diluted net loss per share of $0.41 for the same period of 2016.

As of September 30, 2017, there were approximately 42.4 million shares of common stock outstanding.
