Achaogen Awarded $2.4 Million Contract Option by NIAID to Support Development of LpxC Inhibitors for the Treatment of Serious Bacterial Infections

SOUTH SAN FRANCISCO, Calif., April 21, 2016 (GLOBE NEWSWIRE) -- Achaogen, Inc. (NASDAQ:AKAO), a clinical-stage biopharmaceutical company developing novel antibacterials addressing multi-drug resistant (MDR) gram-negative infections, today announced that it has been awarded an additional $2.4 million under an existing contract with the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), an agency of the United States Department of Health and Human Services.

The award will fund the continued research and development of Achaogen’s LpxC inhibitors, which are novel small molecule agents for the potential treatment of bacterial infections, including those resistant to currently available antibiotics. NIAID funding for the LpxC inhibitor research program now totals $4.4 million and, should the remaining contract option be exercised, the total award would reach $5 million.

“This additional support reflects NIAID's ongoing commitment to advance the development of novel drugs to potentially treat multi-drug resistant gram-negative infections,” said Kenneth Hillan, M.B. Ch.B., Achaogen's Chief Executive Officer. “We are excited to continue development of our LpxC inhibitor antibiotic drug candidates with the crucial support of NIAID whose contribution to this effort is helping to advance what may be the first new mechanism against gram-negative infections in over forty years.”

Achaogen is pursuing an advanced series of LpxC inhibitor compounds that are active against Pseudomonas aeruginosa, a common gram-negative pathogen associated with serious illnesses. LpxC is an essential enzyme for the formation of bacterial membranes in gram-negative bacteria that is highly conserved among gram-negative species. The Company has a goal of nominating a clinical candidate from its LpxC inhibitor research program in 2016 and filing an Investigational New Drug (IND) application in 2017.

About the LpxC Inhibitors
LpxC inhibitors have the potential to fill an important unmet medical need in the treatment of gram-negative bacterial infections, and additionally have the potential to treat infections caused by biothreat pathogens. LpxC inhibition would represent the first new mode of action in over forty years for the treatment of antibiotic-resistant gram-negative bacterial infections. Achaogen's LpxC inhibitor program is currently in the preclinical stage of development. As the program continues with contract funding from NIAID, the Company will apply the significant knowledge it has gained from research and clinical studies of LpxC inhibitors.

About NIAID and NIH
The National Institute of Allergy and Infectious Diseases (NIAID) conducts and supports research - at the National Institutes of Health (NIH), throughout the United States, and worldwide - to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News releases, fact sheets and other NIAID-related materials are available on the NIAID Web site at

The NIH - The Nation's Medical Research Agency - includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. It is the primary federal agency for conducting and supporting basic, clinical and translational medical research, and it investigates the causes, treatments and cures for both common and rare diseases.
