  • Completed Enrollment in Phase 1 PK/Safety Study of Epetraborole in Healthy Volunteers in Japan
  • Plan to Include Japanese Patients in EBO-301 Pivotal Phase 2/3 Trial; Gained Alignment with the PMDA on the Use of a Microbiological Primary Endpoint to Support Potential Registration in Japan

MENLO PARK, Calif., Aug. 11, 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 reported financial results for the quarter ended June 30, 2022.

“We’ve made significant strides with the epetraborole clinical program, initiating the pivotal Phase 2/3 trial in treatment-refractory MAC lung disease in the U.S., and completing enrollment in a Phase 1 study in healthy volunteers in Japan. Furthermore, we recently gained alignment with the PMDA on the registrational path in Japan, including the use of a microbiological endpoint as the basis for potential approval. As a result, the company is planning to include Japanese patients in our ongoing pivotal Phase 2/3 trial,” said Eric Easom, President and Chief Executive Officer. "Initiating the pivotal study for epetraborole in the U.S. and paving the way to add Japanese patients to the study is an important milestone for AN2 and patients suffering from NTM lung disease. With the highest incidence of NTM globally, Japan is an important part of our epetraborole strategy.”

Second Quarter & Recent Business Updates:

Initiated Pivotal Phase 2/3 Trial for Epetraborole in Treatment-Refractory MAC Lung Disease. In June 2022, AN2 Therapeutics reported that it screened its first patient in its pivotal Phase 2/3 clinical trial evaluating once-daily, oral epetraborole for treatment-refractory Mycobacterium avium complex (MAC) lung disease, the most common form of nontuberculous mycobacterial (NTM) lung disease.

Expanded Company’s Board of Directors. During the second quarter of 2022, AN2 Therapeutics announced that Maggie FitzPatrick, a corporate affairs, communications and business operations leader, was appointed to its Board of Directors. Ms. FitzPatrick previously served as Global Chief Communications Officer and led public affairs at Johnson & Johnson.

Advancing Epetraborole Clinical Development. AN2 Therapeutics has completed enrollment in the Phase 1 safety and pharmacokinetics (PK) study of oral epetraborole in healthy volunteers in Japan. The Company recently met with the Japanese Pharmaceutical and Medical Devices Agency (PMDA) and gained alignment on the use of a microbiological primary endpoint to support potential registration in Japan. The Company is planning to include Japanese patients in the EBO-301 pivotal Phase 2/3 clinical trial and expects that data from the ongoing pivotal Phase 2/3 clinical trial of oral epetraborole for treatment-refractory MAC lung disease, if positive, will serve as the basis for the application for marketing approval in Japan.

Financial Results for Second Quarter 2022:

  • Research and Development (R&D) Expenses: R&D expenses increased for the three months ended June 30, 2022, compared to the same period during 2021 due to higher clinical trial activity, additional R&D personnel and related expenses, increased outside consultant costs and research studies related to our research and development activities. These increases were partially offset by lower clinical manufacturing costs for our clinical trials and lower related party license fees.
  • General and Administrative (G&A) Expenses: G&A expenses increased for the three months ended June 30, 2022, compared to the same period during 2021 due to additional G&A personnel and related expenses, higher outside legal and accounting professional service costs and increased consulting services, as we expanded our post-initial public offering (IPO) activities.
  • Cash Position: Cash, cash equivalents and investments totaled $115.8 million on June 30, 2022. The Company expects that current cash, cash equivalents and investments, including net proceeds from the underwriters’ IPO over-allotment option exercised in April, will be sufficient to fund its operating expenses through mid-2024.
