AN2 Therapeutics Reports Second Quarter 2024 Financial Results and Recent Business and Scientific Highlights

Cash, cash equivalents, and investments of $104.5 million at June 30, 2024; cash runway anticipated to fund operations through 2027

AN2 Therapeutics, Inc. (Nasdaq: ANTX), a biopharmaceutical company focused on discovering and developing novel small molecule therapeutics derived from its boron chemistry platform today reported financial results for the quarter ended June 30, 2024.

“We reported results from the EBO-301 Phase 2/3 study in patients with treatment-refractory MAC lung disease last week and over the coming months will further analyze the data to determine next steps in NTM lung disease,” said Eric Easom, Co-Founder, Chairman, President and CEO. “Despite this setback, we remain well positioned as a company - we have a boron chemistry platform with two development programs that are expected to advance into clinical trials in 2025. AN2-502998 is expected to enter Phase 1 with an aim to cure chronic Chagas disease, a potentially life-threatening illness that causes severe cardiac disease and where there are limited to no treatment options. We also plan to initiate a Phase 2 trial with epetraborole for the treatment of melioidosis, a deadly bacterial infection and global bioterrorism threat. Additionally, we have a pipeline of internally developed boron-based compounds in research targeting high unmet needs in infectious disease and oncology and we have the financial runway to allow us to achieve multiple inflection points over the next three years.”

Second Quarter & Recent Business Updates:

Termination of Epetraborole Pivotal Phase 2/3 Clinical Study in TR-MAC Lung Disease

AN2 recently announced topline results from the Phase 2 part of the EBO-301 Phase 2/3 study evaluating epetraborole on top of an optimized background regimen in treatment-refractory MAC lung disease. The Phase 2 part of the study met its primary objective of demonstrating the potential validation of a novel patient-reported outcome (PRO) tool and a higher PRO-based clinical response rate in the epetraborole + OBR arm vs. placebo + OBR. However, sputum culture conversion at Month 6, a key secondary endpoint, was similar between treatment arms. Based on the topline data, the Company has terminated the Phase 2 and Phase 3 parts of the EBO-301 trial. Oral epetraborole 500 mg daily was generally well-tolerated and the study was not terminated due to safety concerns. The Company plans to further analyze the EBO-301 data to better understand the results and their impact on the ongoing development of epetraborole for nontuberculous mycobacteria (NTM) lung disease.

Published New Epetraborole Data in Antimicrobial Agents in Chemotherapy

In July, the company published a study in the journal Antimicrobial Agents in Chemotherapy, which highlighted the efficacy of epetraborole against M. abscessus in a mouse lung infection model. The study suggests that epetraborole could become an important therapy to address the high unmet need for effective oral treatment options for M. abscessus lung disease.

Selected Second Quarter Financial Results

• Research and Development (R&D) Expenses: R&D expenses for the second quarter of 2024 were $12.1 million compared to $13.5 million for the same period during 2023 due to decreased chemistry manufacturing and controls activity and decreased expenses for completed Phase 1 clinical trials, partially offset by increased Phase 2/3 clinical trial costs, increased consulting and outside service costs and increased personnel-related expenses.
• General and Administrative (G&A) Expenses: G&A expenses for the second quarter of 2024 were $3.7 million compared to $3.1 million for the same period during 2023 due to an increase in personnel-related expenses and professional and outside services.
• Other Income, Net: Other income, net for the second quarter of 2024 was $1.4 million compared to $0.8 million for the same period during 2023 due to increased interest income based on higher interest rates and higher cash, cash equivalents and investment balances.
• Net loss: Net loss for the second quarter of 2024 was $14.4 million, compared to $15.8 million for the same period during 2023.
• Cash Position: The Company had cash, cash equivalents, and investments of $104.5 million at June 30, 2024, which is expected to fund operations through 2027.
