Achaogen Wins CARB-X Funding Award to Advance Development of LpxC Inhibitor Antibiotic to Fight Drug Resistant Infections

-- CARB-X funding highlights Achaogen’s innovative LpxC program and urgent need for gram-negative antibiotics --

-- Awarded $3.2 million over 12 months, and potentially up to a total award of $11.4 million --

SOUTH SAN FRANCISCO, Calif., July 25, 2017 (GLOBE NEWSWIRE) -- Achaogen, Inc. (NASDAQ:AKAO), a late-stage biopharmaceutical company developing novel antibacterials addressing multi-drug resistant (MDR) gram-negative infections, today announced a collaboration with CARB-X (Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator), a global public-private partnership focused on funding the development of promising new antibiotics and rapid diagnostics.

CARB-X selected Achaogen from a group of 368 companies and research groups worldwide to be a recipient of the award to support the development of its new class of antibiotic designed to inhibit LpxC. Achaogen was awarded $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.

“We are honored to have CARB-X’s support in helping to advance our lead LpxC inhibitor through initial Phase 1 clinical trials, and we are hopeful that our approach to disrupting the bacterial outer membrane may yield a new way to protect patients from bacterial infections,” said Kenneth Hillan, M.B. Ch.B., Achaogen's Chief Executive Officer. “LpxC is an essential enzyme in most gram-negative bacteria for the biogenesis of the bacterial outer membrane, which is a significant barrier that protects these pathogens from the extracellular milieu.”

Kevin Outterson, Executive Director of CARB-X and Professor of Law at Boston University said, “Drug-resistant infections are complex and developing new antibiotics challenging, timely and costly. But restoring the R&D pipeline is vital to address the seriously increasing threat of superbugs which have become resistant to existing drugs. This is a global problem and CARB-X is a critical part of the global solution. We are looking to support the best potential new treatments and diagnostics across the world. We are especially pleased that today’s awards mean we are now supporting scientists in six countries. The projects offer exciting potential. But we need greater global support from governments, industry and civil society to get the new treatments the world urgently needs.”

About LpxC Inhibitors - A New Class of Antibiotics
LpxC is an essential enzyme unique to gram-negative bacteria. Inhibition of LpxC can disrupt the structural integrity of the bacterial outer membrane, leading to rapid bacterial cell lysis. Owing to its critical role in maintaining the barrier function of the outer membrane, LpxC is essential in nearly all Gram-negative bacteria studied to date. Achaogen’s lead LpxC inhibitor has shown potent activity against Pseudomonas aeruginosa and is being developed to potentially treat infections due to this multidrug-resistant pathogen. Pseudomonas aeruginosa is on the World Health Organization’s top priority list of drug-resistant bacteria. Learn more about LpxC inhibitors.

About Achaogen
Achaogen is a late-stage biopharmaceutical company passionately committed to the discovery, development, and commercialization of innovative antibacterial treatments for MDR gram-negative infections. Achaogen is developing plazomicin, Achaogen’s lead product candidate, for the treatment of serious bacterial infections due to MDR Enterobacteriaceae, including carbapenem-resistant Enterobacteriaceae. Achaogen’s plazomicin program is funded in part with a contract from the Biomedical Advanced Research and Development Authority. Plazomicin is the first clinical candidate from Achaogen’s gram-negative antibiotic discovery engine. Achaogen has other programs in early and late preclinical stages focused on other MDR gram-negative infections, including LpxC inhibitors for the treatment of serious bacterial infections including MDR gram-negative bacteria. Achaogen's LpxC inhibitor program has been funded in part with Federal funds from the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN272201500009C. The LpxC inhibitor program will be funded in part with funds from Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator (CARB-X). All product candidates are investigational only and have not been approved for commercialization.  For more information, please visit
