-- Plazomicin granted Breakthrough Therapy designation --

-- C-Scape Phase 1 study underway to evaluate orally-administered antibacterial candidate for infections due to ESBL-producing Enterobacteriaceae --

-- Conference call today at 4:30 p.m. Eastern Time --

SOUTH SAN FRANCISCO, Calif., Aug. 03, 2017 (GLOBE NEWSWIRE) -- Achaogen, Inc. 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 second quarter 2017, and provided an update on its corporate and clinical development activities.

"We made excellent progress this quarter including being granted FDA Breakthrough Therapy designation for plazomicin, securing more than a dozen plazomicin presentations at ASM Microbe, and dosing the first patient in our C-Scape clinical development program," said Kenneth Hillan, M.B. Ch.B., Achaogen's Chief Executive Officer. "Our planned plazomicin NDA application is our top priority and we remain on track to file the NDA in 2017."

Recent Highlights and Upcoming Milestones

Plazomicin has successfully completed two Phase 3 clinical trials and the Company continues to plan to submit a New Drug Application (NDA) to the Food and Drug Administration (FDA) in the second half of 2017 and 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 registration 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.

• The U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation for plazomicin for the treatment of bloodstream infections (BSI) caused by certain Enterobacteriaceae in patients who have limited or no alternative treatment options.
• Presented data at ASM Microbe that highlighted the potential of plazomicin against MDR gram-negative bacteria in clinical and non-clinical settings. Thirteen abstracts were accepted, including oral presentations of the Phase 3 EPIC and CARE clinical trials:
  • New analyses of the Phase 3 EPIC trial highlighted the favorable efficacy of plazomicin in the subgroup of patients with bacteremia, and a statistically higher rate of microbiological eradication and a lower infection relapse rate in plazomicin-treated patients compared to meropenem at the late follow-up visit (LFU) time point; and
  • Further analyses of the Phase 3 CARE trial highlighted that plazomicin was associated with a higher microbiological response rate compared to colistin and, in terms of key safety outcomes, was associated with a lower incidence and magnitude of serum creatinine increases compared to colistin.

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.

• Treated the first human subject with C-Scape in a Phase 1 clinical pharmacology, dosing and safety study; if successful, plan to proceed to pivotal Phase 3 cUTI trial initiation in the first half of 2018.

Other Corporate Highlights

• Completed an underwritten public offering of 5,750,000 shares of its common stock at a price of $22.50 per share, which included the exercise in full of the underwriters' option to purchase an additional 750,000 shares of common stock. Net proceeds were approximately $121.2 million after deducting discounts, commissions and offering expenses.
• Appointed Dr. Karen Bernstein, Co-Founder and Chairman of BioCentury Inc., to its Board of Directors.
• Awarded a grant by Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator (CARB-X), an international antimicrobial consortium to accelerate global antibacterial innovation and research, to support the development of LpxC; the grant consists of $3.2 million over 12 months, and potentially up to a total award of $11.4 million after that period upon achievement of certain milestones.

Second Quarter 2017 Financial Results

Cash, cash equivalents and short-term investments totaled $230.3 million, and restricted cash totaled $12.6 million at June 30, 2017.  

Contract revenue totaled $1.3 million for the second quarter of 2017 compared to $9.1 million for the same period of 2016. The decrease in contract revenue during the quarter was primarily due to full utilization of BARDA funding available under the current contract.

Research and development (R&D) expenses were $22.2 million for the second quarter of 2017 compared to $21.7 million reported for the same period in 2016. The increase in R&D expenses during the quarter was attributable to increase in personnel and facility related costs as net headcount increase in our research and development organization, increase of external expenses related to C-Scape clinical program, offset by decreases related to the plazomicin clinical and other research programs.

General and Administrative (G&A) expenses were $8.9 million for the second quarter of 2017 compared to $4.0 million for the same period in 2016. The increase in G&A expenses during the quarter was primarily attributable to increase in personnel and facility related costs, and in costs related to preparation for the commercialization of plazomicin.

Net loss for the second quarter of 2017 was $26.1 million compared to net loss of $18.3 million for the second quarter of 2016. Diluted net loss per share were $0.78 in the second quarter of 2017, compared to diluted net loss per share of $0.87 in the second quarter of 2016.

As of June 30, 2017, there were approximately 42.2 million shares of common stock outstanding.
