AN2 Therapeutics Reports Fourth Quarter and Full Year 2022 Financial Results and Recent Highlights

• Approaching 60 clinical sites participating in pivotal Phase 2/3 trial of epetraborole in treatment-refractory Mycobacterium avium complex (MAC) lung disease to date
• Opened up sites in three additional countries — Japan, South Korea, and Australia in addition to the U.S.; Japan has some of the highest rates of MAC lung disease in the world
• Activities underway to advance development of epetraborole for acute systemic melioidosis using non-dilutive funding

MENLO PARK, Calif.–(BUSINESS WIRE)–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 reported financial results for the fourth quarter and year ended December 31, 2022.

�2022 was a transformative year for AN2 as we transitioned from a private company into a public company and initiated a single pivotal Phase 2/3 clinical trial, EBO-301, for epetraborole in treatment-refractory MAC lung disease. We continued to generate data that support the potential of epetraborole to meet an ideal target product profile for NTM lung disease caused by MAC. Importantly, based on discussions with FDA and the Japanese Pharmaceuticals and Medical Devices Agency (PMDA), we believe that our pivotal trial, if positive, will be sufficient to support regulatory filings in these two major markets. We also gained alignment with the PMDA on the use of a microbiological primary endpoint to support potential registration and received orphan medicinal product designation from the European Union,” said Eric Easom, Co-Founder, President and Chief Executive Officer. “Enrollment is ongoing in the Phase 2/3 pivotal trial of epetraborole. We are approaching 60 clinical sites worldwide, including new sites in Japan, South Korea and Australia. Japan has some of the highest rates of MAC lung disease in the world, making it and the broader Asia-Pacific region an area of particular importance as we look to make a significant impact on the lives of patients worldwide.”

Highlighting the company’s commitment to global health using non-dilutive funding, AN2 was awarded a contract in the third quarter of 2022 valued up to $17.8M from the National Institute of Allergy and Infectious Disease to develop epetraborole for acute systemic melioidosis and other biothreat pathogens. “Melioidosis affects an estimated 165,000 patients globally with an unacceptably high mortality rate of up to 60% left untreated. We believe epetraborole can play a key role in reducing mortality as well as provide a countermeasure to a serious biothreat agent,” said Easom.

Fourth Quarter & Recent Business Updates:

Advanced Epetraborole Pivotal Phase 2/3 Clinical Study.

The Company is currently enrolling its Phase 2/3 pivotal trial evaluating once-daily, oral epetraborole for treatment-refractory MAC lung disease. We expect to complete enrollment in the Phase 2 portion of the pivotal Phase 2/3 clinical trial in mid-2023 and plan to seamlessly begin enrollment of the Phase 3 portion of the trial immediately thereafter. We expect to announce top-line data for each of the Phase 2 and Phase 3 portions of the trial approximately nine months after the completion of enrollment in each respective portion of the trial.

In 2022, the FDA granted epetraborole Fast Track designation for treatment-refractory MAC lung disease, Qualified Infectious Disease Product designation for treatment-refractory MAC lung disease, and orphan-drug designation for the treatment of infections caused by NTM.

Announced Epetraborole Data from Phase 1 Study in Japanese Subjects that Supports Use of Once-Daily 500 mg Dose in Japanese Patients.

In October, the Company announced results from a Phase 1 study designed to evaluate the pharmacokinetics, safety, and tolerability of oral epetraborole administered as a single 500 mg dose to healthy Japanese volunteers with different alcohol dehydrogenase (ADH) genotypes. The study showed that epetraborole was well tolerated at this dosage and supports use in Japanese patients enrolled in the ongoing Phase 2/3 pivotal trial.

Presented New Epetraborole Data at the Infectious Disease Society of America (IDSA) IDWeek 2022 Conference.

In October, the Company presented one oral presentation and nine data poster presentations at the ID Week Conference highlighting new data supporting the potential for epetraborole in nontuberculous mycobacteria (NTM) lung disease.

Granted Orphan Medicinal Product Designation in NTM Lung Disease in European Union.

In October, the Company announced that it received the orphan medicinal product designation for epetraborole in NTM lung disease from the European Commission, which grants orphan medicinal product designation to medicines intended for the treatment, prevention or diagnosis of a life-threatening or very serious condition. The designation provides various incentives, including ten-year market exclusivity upon regulatory approval, if received, fee reductions, and access to protocol assistance.

Selected Fourth Quarter and Full Year 2022 Financial Results

• Research and Development (R&D) Expenses: R&D expenses for the full year 2022 were $29.5 million, compared to $16.9 million in the prior year. R&D expenses for the fourth quarter of 2022 were $8.7 million, compared to $5.8 million for the same period last year.
• General and Administrative (G&A) Expenses: G&A expenses for the full year 2022 were $12.8 million, compared to $4.7 million in the prior year. General and administrative expenses for the fourth quarter of 2022 were $3.7 million, compared to $1.8 million for the same period last year. Most of the increase is attributable to being a publicly-traded company.
