Exhibit 99.1
AN2 Therapeutics Reports Third Quarter 2024 Financial Results, Provides Important EBO-301 Update and Highlights Progress Across Boron Chemistry Pipeline
Epetraborole-treated patients demonstrated clinical improvements in QOL-B and a post-hoc analysis of MACrO2 with nominal statistical significance when evaluated as continuous measures
First drug candidate with statistically favorable patient reported outcome (PRO)-based improvement in treatment-refractory Mycobacterium avium Complex (TR-MAC) population
Company plans to meet with FDA to gain alignment on a development path for epetraborole, including potentially reinitiating a Phase 3 clinical study, while advancing its boron chemistry pipeline
Achieved 50% reduction in expenditures through strategic realignment of operations
Cash, cash equivalents, and investments of $93.4 million at September 30, 2024 anticipated to fund operations through 2027 under current operating plan
Menlo Park, CA – November 13, 2024 – 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 September 30, 2024 and provided an update from its ongoing analysis of data from the Phase 2 portion of the EBO-301 trial.
“Treatment options for patients with refractory MAC lung disease are extremely limited. Many of these patients are significantly more challenging to convert microbiologically due to the microbial complexity of their infections as well as their very complex lung anatomy, and often experience severe clinical symptoms at this advanced stage of disease. The fact that epetraborole appears to have demonstrated improvements based on two patient reported outcome measures is highly encouraging,” said Stephen J. Ruoss, M.D., Professor of Medicine, Pulmonary and Critical Care Medicine at Stanford University School of Medicine. “By potentially improving both their quality of life and clinical outcomes, epetraborole represents a potentially significant advancement in treatment possibilities.”
“We are encouraged by this recent data analysis, which indicate that epetraborole may provide clinical improvement in patients with treatment-refractory MAC lung disease, as measured by two patient-reported outcome instruments, including the same instrument recently selected for the primary endpoint in the Arikayce TN-MAC pivotal trial,” stated Eric Easom, Co-Founder, Chairman, President, and Chief Executive Officer of AN2 Therapeutics. “We look forward to engaging with the FDA in the near-term to discuss next steps for the epetraborole program, including the potential reinitiation of a pivotal Phase 3 trial for treatment-refractory MAC lung disease.”
Easom continued, “With a strong cash runway and optimized operating plan, we continue to advance our diverse pipeline of boron-based compounds to address unmet patient needs. This includes the recent strategic expansion into oncology, underscoring our dedication to innovating and improving patient outcomes across multiple therapeutic areas.”
Third Quarter & Recent Updates:
Ongoing Analysis from Epetraborole Phase 2/3 Clinical Study in TR-MAC Lung Disease
The Company has provided an update from its ongoing analysis of the Phase 2 portion of the EBO-301 Phase 2/3 study. Two PROs evaluated in the trial indicated statistically significant clinical response, the QOL-B Respiratory Domain (Table 1) and MACrO2 (post-hoc analysis, Table 2), using continuous response measures instead of the binary responder methodology previously reported. Patients treated with epetraborole indicated clinical response using the same PRO instrument (QOL-B respiratory domain) and analysis method (least squares mean change from Baseline to Month 6) that was recently reported as the primary endpoint in the Arikayce ENCORE trial, after alignment with FDA. These EBO-301 PRO findings appear to align with FDA’s current recommendation for PRO-based primary endpoints in NTM-MAC trials.

*Measures of patient improvement for MACrO2 are shown by negative changes in the score measured from baseline. The least squares mean calculation for MACrO2 utilized the same approach as the prespecified QOL-B LSM in the EBO-301 statistical analysis plan.
There was a high rate of MAC resistance to background antimycobacterial therapies at baseline, including approximately one-third of the patients with macrolide resistance and 60% with amikacin resistance, indicators of the complexity of the patient population. Notably, there was no evidence of induced epetraborole resistance in isolates from patients treated with epetraborole.
Further analysis showed no change in the previously reported safety profile; epetraborole was generally well-tolerated, with 2 (5%) discontinuations due to TEAEs in the epetraborole arm.
Epetraborole:Next Steps
The Company believes these findings are particularly noteworthy given the severe refractory status of the patients studied, and that improvements in QOL-B and MACrO2 appear to align with FDA’s current guidance for the primary efficacy endpoint in NTM-MAC studies. The Company will seek an End-of-Phase 2 meeting with FDA in the first half of 2025, with the goal of leveraging insights from the Phase 2 results to evaluate potential reinitiation of a pivotal Phase 3 TR-MAC study. In addition, the Company also plans to seek alignment with the FDA on a statistical analysis plan for the 97 patients who completed six months of treatment in the Phase 3 portion of EBO-301 at the time the Company halted the trial in August 2024. The Company anticipates releasing top-line Phase 3 data from these patients in mid-2025, subject to the timing of discussions with the FDA.
Other AN2 Boron Chemistry Pipeline Programs
Chagas Disease
During the quarter, the Company advanced preclinical activities aimed to initiate clinical studies in chronic Chagas disease, a disease that affects an estimated 6-7 million people worldwide, including approximately 300,000 in the U.S., and causes severe cardiac disease and death. The Company plans to initiate Phase 1 clinical development with AN2-502998 in mid-2025.
Melioidosis
The Company completed enrollment in a 200-patient observational trial for epetraborole in acute melioidosis in October 2024 and these data will inform a Phase 2 proof of concept study that is planned to initiate enrollment in the second half of 2025. Melioidosis is a deadly bacterial infection and global bioterrorism threat with a 90-day mortality rate of approximately 50% using standard of care (SOC) drugs ceftazidime or meropenem. The aim of the program is to meaningfully lower the expected mortality rate by dosing epetraborole on top of SOC.
Boron Chemistry Pipeline
Additional development programs are underway and focused on targets in infectious diseases and oncology with high unmet needs. The Company anticipates delivering up to three development compounds in 2025.
Global Health
In October, the Company announced that it received a second-year continuation of a research grant from the Bill & Melinda Gates Foundation to discover novel boron containing small molecules for the treatment of tuberculosis and malaria. The Company will continue its efforts to tackle global health disease through non-dilutive funding.
