Achaogen Provides Clinical Update and First Quarter 2015 Results

SOUTH SAN FRANCISCO, May 11, 2015 (GLOBE NEWSWIRE) -- Achaogen, Inc. (Nasdaq:AKAO), a clinical-stage biopharmaceutical company developing novel antibacterials to treat multi-drug resistant (MDR) gram-negative infections, today reported an update of its Phase 3 plazomicin clinical programs as well as financial results for the quarter ended March 31, 2015.

"Enhancing and advancing the plazomicin development plan following discussions with the FDA was a key accomplishment for the quarter," commented Kenneth Hillan, Chief Executive Officer of Achaogen. "The severity and scale of the global threat of multi-drug resistant bacterial infections continues to grow, and we see the regulatory, legislative, and commercial landscapes evolving in recognition of this unmet medical need. The actions that we have taken position Achaogen to help address these emergent opportunities and make an important contribution to the treatment of patients with limited therapeutic options."

The Company's lead compound, plazomicin, is being developed to treat serious bacterial infections due to Enterobacteriaceae, including carbapenem-resistant Enterobacteriaceae (CRE), and is currently being evaluated in patients with bloodstream infections (BSI) and pneumonia due to CRE in a Phase 3 study titled CARE (Combating Antibiotic Resistant Enterobacteriaceae). In the first quarter, the Company announced an enhanced development plan for plazomicin including the addition of a Phase 3 study in patients with complicated urinary tract infections (cUTI). This additional study significantly expands the market opportunity for plazomicin to include the population of patients with cUTI infections caused by MDR Enterobacteriaceae. In addition, it provides a nearer-term pathway to seek regulatory approval of plazomicin in the United States. Finally, it enhances the probability of technical and regulatory success of the plazomicin program given the success of plazomicin in the prior Phase 2 cUTI study. Based on discussions with the US Food and Drug Administration (FDA), Achaogen expects the Phase 3 cUTI trial to serve as a single pivotal study to support regulatory approval of plazomicin. The trial is expected to commence in Q4 2015 with top-line results and an NDA submission expected in the second half of 2017.

The Phase 3 cUTI trial will be a randomized, double blind, active controlled study in patients with cUTI and acute pyelonephritis.  This will be a non-inferiority trial comparing plazomicin to meropenem with a 15% non-inferiority (NI) margin. As such, the trial will have a sample size of approximately 530 patients, which is significantly smaller than prior industry-sponsored Phase 3 cUTI trials. The Company believes that this reflects the FDA's recognition of the unmet need for new antibiotics that treat MDR bacterial infections with high morbidity and mortality. The Company estimates the Phase 3 cUTI trial will necessitate additional Achaogen funding of $45-50 million from 2015 through 2017, which the Company anticipates will be primarily accessed via non-dilutive sources such as government contracts, grants, and debt.

The on-going Phase 3 CARE study will provide data in patients with BSI and pneumonia infections due to CRE, and is expected to enable label expansion following an initial approval based on the cUTI study. The Company has worked with the FDA on a protocol amendment with the goal of improving patient enrollment in the CARE study. The amendment also changes the primary endpoint to include not only mortality, but also other significant disease-related complications, which increases the statistical power of the study and which the Company also believes provides a more sensitive measure of the antibiotic treatment effect.  Achaogen's goal is to complete the CARE study, and submit a supplemental NDA during the second half of 2018.

On the corporate front, the Company announced the appointments of Dr. Alan Colowick and Dr. Kent Lieginger to its Board of Directors.  Dr. Colowick has held senior managerial positions at large and emerging biotechnology companies. Most recently at Celgene Corporation, he served as President for the Europe, Mid-East, and Africa region from 2012 to 2014 and Senior Vice President Global Medical Affairs from 2010 to 2012. Dr. Lieginger was most recently Senior Vice President, Managed Care and Customer Operations at Genentech, Inc., as well as Director of the Genentech Foundation since 2005. He originally joined Genentech as Vice President, Managed Care and Customer Operations in 2004 and served as a member of Genentech's Commercial Leadership Committee.

Summary Financial Results for the Quarter Ended March 31, 2015

Cash, cash equivalents and short-term investments totaled $61.6 million at March 31, 2015 compared to $63.7 million at December 31, 2014, decreasing as a result of operating losses.

Revenues totaled $4.9 million for the first quarter of 2015 compared to $6.0 million for the comparable quarter in 2014. Achaogen derived all of its revenue from funding provided under U.S. government contracts in connection with the development of product candidates.

Research and development (R&D) expenses totaled $7.9 million for the first quarter of 2015 compared to $6.6 million for the comparable quarter in 2014. Increased R&D costs for the quarter were primarily attributable to increased activities for research programs other than plazomicin and higher personnel related costs.

General and administrative (G&A) expenses totaled $3.2 million for the first quarter of 2015 compared to $2.6 million for the comparable quarter in 2014. Increased costs were primarily attributable to higher personnel-related costs including stock-based compensation expenses and increased costs associated with being a public company.

Net loss totaled $6.2 million for the first quarter of 2015 compared to $3.5 million for the same period of 2014.
