AN2 Therapeutics Reports Third Quarter 2022 Financial Results and Provides Business Updates


U.S. Enrollment Ongoing in EBO-301 Pivotal Phase 2/3 Clinical Trial of Epetraborole in Treatment-Refractory MAC Lung Disease; Plan to Include Japanese Patients in Trial
Awarded Contract from NIAID Valued Up to $17.8 Million to Advance Development of Epetraborole for Acute Systemic Melioidosis


Menlo Park, CA – November 9, 2022 – 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 quarter ended September 30, 2022.


“Chronic lung infections, such as Mycobacterium avium complex (MAC) lung disease, are debilitating and can be fatal. AN2 Therapeutics is committed to developing more effective solutions for patients and healthcare providers that are seeking new treatment options. Over the past several months we’ve continued to advance our epetraborole development strategy. Enrollment is ongoing in our pivotal Phase 2/3 clinical trial in treatment-refractory (MAC) lung disease, and we’ve taken important steps to include Japanese patients in the pivotal trial based on data from our recent Phase 1 trial conducted in Japanese subjects, which supports the use of a single 500-mg daily oral dose of epetraborole and validated data from previous studies. Also, new data recently presented at IDWeek further validates the potential of epetraborole,” said Eric Easom, Co-Founder, President and Chief Executive Officer. "Finally, the recent decision by the National Institutes of Allergy and Infectious Diseases (NIAID) to award AN2 Therapeutics a contract for the development of epetraborole in acute systemic melioidosis, an infectious disease with unacceptably high mortality that also poses a serious biothreat, underscores the potential of epetraborole, which has shown significant promise across preclinical models of infection. We will continue to explore the utility of epetraborole in areas with urgent unmet global health needs that will allow us to capture synergies with our existing epetraborole program.”

Third Quarter & Recent Business Updates:

Advanced Epetraborole Clinical Development. Enrollment is ongoing in the Company’s pivotal Phase 2/3 clinical trial evaluating once-daily, oral epetraborole for treatment-refractory MAC lung disease, the most common form of nontuberculous mycobacterial (NTM) lung disease. The Company expects to complete enrollment in the Phase 2 part of the pivotal Phase 2/3 clinical trial in mid-2023 and plans 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.

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. Results of the study showed that no subjects experienced treatment-emergent adverse events and support use of AN2’s recommended dose in Japanese patients enrolled in its ongoing pivotal Phase 2/3 clinical trial, regardless of ADH genotype.

Received Orphan Medicinal Product Designation for Epetraborole in the European Union. In August, the Company received the orphan medicinal product designation for epetraborole in NTM lung disease from the European Commission.

Presented New Epetraborole Data at Infectious Disease Society of America (IDSA) IDWeek 2022 Conference. In October, AN2 presented nine poster presentations and one oral presentation that advance the understanding of epetraborole in NTM lung disease.

Awarded Contract by National Institute of Allergy and Infectious Diseases (NIAID) to Advance Development of Epetraborole for Acute Systemic Melioidosis. In September, AN2 announced the award of a contract valued up to $17.8 million from the NIAID, part of the National Institutes of Health (NIH), to advance the development of epetraborole for acute systemic melioidosis and other biothreat pathogens.



Strengthened Senior Leadership Team. In September, Joshua M. Eizen was appointed Chief Legal Officer and Secretary. Mr. Eizen brings significant industry experience to AN2, including as counsel to Jazz Pharmaceuticals, GW Pharmaceuticals and the U.S. Food and Drug Administration.

Financial Results for Third Quarter 2022:

Research and Development (R&D) Expenses: R&D expenses increased for the three months ended September 30, 2022, compared to the same period during 2021 due to a related party license fee associated with dosing of the first patient in our pivotal Phase 2/3 clinical trial, increased clinical trial activity, additional R&D personnel and related expenses, and increased outside services and consultant costs. These increases were partially offset by lower outside research and toxicology study costs related to our development activities.
General and Administrative (G&A) Expenses: G&A expenses increased for the three months ended September 30, 2022, compared to the same period during 2021 due to additional G&A personnel and related expenses, increased insurance and other expenses, and increased outside legal and consulting services costs as we conducted business as a public company. These increases were partially offset by lower accounting professional fees compared to 2021 fees related to preparation for AN2’s Initial Public Offering.
Cash Position: Cash, cash equivalents and investments totaled $106.4 million on September 30, 2022. The Company expects that current cash, cash equivalents and investments will be sufficient to fund its operating expenses through mid-2024.
