• Non-dilutive funding will drive synergies with existing epetraborole development program for NTM lung disease
  
• Award leverages AN2 Therapeutics expertise and commitment to address urgent unmet global health needs
• Work could help address U.S. biothreat pathogen
  

MENLO PARK, Calif., Sept. 29, 2022 (GLOBE NEWSWIRE) -- AN2 Therapeutics, Inc. (Nasdaq: ANTX), a clinical-stage biopharmaceutical company focused on developing treatments for rare, chronic, and serious infectious diseases with high unmet needs, today announced the award of a contract valued up to $17.8 million from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), to advance the development of epetraborole for acute systemic melioidosis. The base period contract is $4.3 million with additional options that, if exercised, will total $17.8 million to support preclinical, Phase 1 studies and other activities to enable advancement of epetraborole into a pivotal Phase 2/3 clinical trial for acute systemic melioidosis. AN2 Therapeutics is currently developing epetraborole in an ongoing pivotal Phase 2/3 trial for treatment refractory Mycobacterium avium complex (MAC) lung disease, the most common form of nontuberculous mycobacterial (NTM) lung disease.

“Melioidosis, a disease caused by the bacteria Burkholderia pseudomallei, is predominately a disease of tropical climates, especially in South Asia and northern Australia where it is widespread. However, B. pseudomallei was recently found in the environment along the Gulf Coast in the United States,” said Eric Easom, Co-Founder, President and Chief Executive Officer. “Epetraborole has shown significant promise in non-clinical models of infection for melioidosis and could have the potential to reduce mortality in patients suffering from the disease. In addition to addressing an urgent unmet global health need, this work will aid in addressing a high priority biothreat pathogen and will allow us to capture synergies with our ongoing development of epetraborole for NTM. We are pleased to partner with the NIH on this meaningful global health work that is core to our corporate mission and values.”

This project has been funded in whole with Federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services, under Contract No. 75N93022C00059.

About Melioidosis
Melioidosis is an infectious disease caused by the bacterium B. pseudomallei. It is endemic to tropical regions of the world with the majority of cases occurring in South Asia and Northern Australia, and was recently found in the southern U.S. It is contracted from direct contact with contaminated soil and water and is not transmitted person-to-person. Similar to NTM, B. pseudomallei is an intra-cellular pathogen in macrophages. Infections can manifest as localized infections causing pain, swelling and ulceration; as pulmonary infections causing cough, chest pain, high fever, and headache; and as blood stream infections causing fever, headache, respiratory distress, and abdominal discomfort. Current treatment generally starts with an intense phase of intravenous antibiotic treatment for a minimum of two weeks. Even with antibiotic treatment, the mortality rate is between 20% and 40%. Without treatment, six out of ten people die. There are an estimated 165,000 cases of melioidosis globally each year.
