AN2 Therapeutics, Inc. (Nasdaq: ANTX), a clinical stage biopharmaceutical company focused on the discovery and development of novel small molecule therapeutics derived from its boron chemistry platform, today reported financial results for the first quarter ended March 31, 2026.

“This was an important quarter for AN2 as we announced an exciting new program in polycythemia vera that is planned to enter Phase 2 development in the third quarter of 2026. This program is supported by what we believe is a robust package of epetraborole preclinical and clinical enabling data. We commenced an investigator-initiated Phase 2 study in M. abscessus lung disease, completed dosing in a Phase 1 study for our Chagas disease program, and declared our ENPP1 candidate for the treatment of solid tumors, as well as strengthened our balance sheet,” said Eric Easom, Co-Founder, Chairman, President and CEO of AN2 Therapeutics. “Looking ahead, we expect to advance three programs into Phase 2 development this year and report multiple data readouts within our cash runway into 2029. I couldn’t be more excited about our progress and the potential to substantially improve the lives of patients across our diverse portfolio that is enabled by our boron chemistry pipeline.”
