Enrollment well underway in Phase 3 part of pivotal Phase 2/3 study of epetraborole in treatment-refractory Mycobacterium avium complex (MAC) lung disease
On track to announce Phase 2 clinical data summer 2024
Cash and investments of $150.2 million at September 30, 2023; cash runway anticipated to fund operations through summer 2025
MENLO PARK, Calif.--(BUSINESS WIRE)-- 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, 2023.
“We are incredibly proud of the significant milestones achieved recently and over the past quarter. In September, we initiated enrollment in the Phase 3 part of our pivotal Phase 2/3 clinical trial for epetraborole in treatment-refractory MAC lung disease after fully enrolling the Phase 2 part of the trial. At IDWeek in October 2023, we presented preclinical data showing the potential for epetraborole to address unmet needs for patients with Mycobacterium abscessus lung infections, for whom current treatment guidelines recommend four or more antibiotics, some of which are IV-only. There is an urgent need for more effective, novel, oral agents for this difficult-to-treat disease,” said Eric Easom, Co-Founder, President and Chief Executive Officer. “In addition to our promising progress on the epetraborole program, and consistent with our company’s mission to support global health programs, we signed key agreements during the quarter that leverage our boron-based platform for global health. Notably, in September, we received a grant from the Bill and Melinda Gates Foundation to discover novel small molecules for the treatment of tuberculosis and malaria, and in October, we announced a license agreement with the University of Georgia Research Foundation to advance the development of AN2-502998, a novel, boron-containing small molecule for Chagas disease.”
Third Quarter & Recent Business Updates:
Initiated Phase 3 Part of Pivotal Phase 2/3 Clinical Trial for Epetraborole. In September, the Company announced that it had commenced the Phase 3 part of the Phase 2/3 clinical trial after fully enrolling 80 patients in the Phase 2 part of the trial evaluating once-daily, oral epetraborole for treatment-refractory MAC lung disease. The trial is being conducted at over 100 clinical sites across the U.S., Japan, South Korea, and Australia. AN2 expects to announce top-line data from the Phase 2 portion of the trial in summer 2024.
Presented New Epetraborole Data at Infectious Disease Society of America (IDSA) IDWeek 2023 Conference. In October, three poster presentations and two oral presentations were presented at the IDWeek 2023 conference that detailed the potential of epetraborole in treating NTM lung disease and melioidosis.
Executed License from University of Georgia Research Foundation to Develop Boron-Containing Product Candidates for Chagas Disease. In October, AN2 announced that it had executed an exclusive license from the University of Georgia Research Foundation to advance the development of a boron-containing small molecule, AN2-502998 (formerly AN15368), for Chagas disease. This boron-based molecule was originally discovered by researchers at Anacor Pharmaceuticals, Inc. (a wholly owned subsidiary of Pfizer) and the University of Georgia, with grant funding from Wellcome. To date, AN2’s preclinical activities have been supported using non-dilutive grant funding from Wellcome and are conducted in partnership with Professor Rick Tarleton, Ph.D., from the University of Georgia, an expert in Chagas disease and Trypanosoma cruzi biology.
Received Grant from Bill & Melinda Gates Foundation. In September, AN2 announced that it received a grant from the Bill & Melinda Gates Foundation to discover novel, boron containing small molecules for the treatment of tuberculosis and malaria.
Selected Third Quarter Financial Results
Research and Development (R&D) Expenses: R&D expenses increased for the three months ended September 30, 2023, compared to the same period during 2022 due to increased clinical trial expenses, personnel-related expenses, consulting and outside services and preclinical and research study expenses, partially offset by lower chemistry manufacturing and controls costs and other expenses.
General and Administrative (G&A) Expenses: G&A expenses increased for the three months ended September 30, 2023, compared to the same period during 2022 due to increased personnel-related expenses and professional service fees, partially offset by a decrease in insurance costs.
Other Income, Net: Other income, net was $1.5 million for the three months ended September 30, 2023, compared to $0.4 million in the same period in 2022 due to increased interest and investment income based on higher interest rates and higher cash, cash equivalents and investment balances.
Net loss: Net loss was $16.7 million for the three months ended September 30, 2023, compared to $11.3 million in the same period during 2022.
Cash Position: On August 15, 2023, the Company sold an aggregate of 7,777,778 shares of the Company’s common stock at a purchase price of $9.00 per share under an underwritten offering. This resulted in aggregate gross proceeds to the Company of approximately $70.0 million, before deducting underwriting discounts and commissions and offering expenses. The Company expects that current cash and investments of $150.2 million at September 30, 2023 will be sufficient to fund its operating expenses through summer 2025.
