Item 8.01 Other Events.

As previously disclosed by BiomX Inc. (“BiomX” or the “Company”) on August 19, 2025, the U.S. Food and Drug Administration (“FDA”) had placed a clinical hold on the Company’s Phase 2b study (the “Study”) that is design to test the Company’s drug candidate BX004 (“BX004”) in treating Cystic Fibrosis (“CF”) as the FDA reviews data submitted by the Company on a third-party nebulizer used in the Study to deliver BX004. Following the FDA’s hold notification the Company submitted additional requested data.

On October 17, 2025, BiomX updated that it had received additional questions from the FDA, which questions were narrow in scope and pertained solely to the nebulizer device, with no concerns raised regarding the BX004 drug product itself. BiomX believes it has fully addressed the FDA queries relating to the third-party nebulizer. Enrollment and dosing in the European portion of the Study continue ahead of plan, and the Study remains on track to report topline results in the first quarter of 2026.

In addition, the Company reported receiving new written feedback from the FDA recognizing the continued unmet medical need for therapies addressing chronic Pseudomonas aeruginosa infection in CF patients and outlining potential development pathways for BX004, including refined inclusion criteria for future studies and approaches to enrich patient populations in a Phase 3 program.

BiomX plans to incorporate the FDA’s recommendations, as appropriate and subject to future data from the Study, regulatory alignment, and resources, into ongoing development plans and anticipates further discussion with the FDA at an End-of-Phase 2 meeting following completion and review of the Phase 2b trial results.

Forward-Looking Statements

This Current Report contains express or implied “forward-looking statements” within the meaning of the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as: “target,” “believe,” “expect,” “will,” “may,” “anticipate,” “estimate,” “would,” “positioned,” “future,” and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. For example, when BiomX refers to the possibility that the data BiomX provided will allow the FDA to lift the clinical hold, the timing of topline results for the Study, the impact of the FDA clinical hold on the Study, FDA feedback recognizing the continued unmet medical need for therapies addressing chronic Pseudomonas aeruginosa infection in CF patients and potential pathways outlined and results of potential future discussions with the FDA, it is using forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on BiomX management’s current beliefs, expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of BiomX’s control. These risks and uncertainties include, but are not limited to, changes in applicable laws or regulations; the possibility that BiomX may be adversely affected by other economic, business, and/or competitive factors, including risks inherent in pharmaceutical research and development, such as: adverse results in BiomX’s drug discovery, preclinical and clinical development activities, the risk that the results of preclinical studies and early clinical trials may not be replicated in later clinical trials, BiomX’s ability to enroll patients in its clinical trials, and the risk that any of its clinical trials may not commence, continue or be completed on time, or at all; decisions made by the FDA, and other regulatory authorities; decisions made by investigational review boards at clinical trial sites and publication review bodies with respect to our development candidates; BiomX’s ability to obtain, maintain and enforce intellectual property rights for its platform and development candidates; its potential dependence on collaboration partners; competition; uncertainties as to the sufficiency of BiomX’s cash resources to fund its planned activities for the periods anticipated and BiomX’s ability to manage unplanned cash requirements; and general economic and market conditions. Therefore, investors should not rely on any of these forward-looking statements and should review the risks and uncertainties described under the caption “Risk Factors” in BiomX’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 25, 2025, and additional disclosures BiomX makes in its other filings with the SEC, which are available on the SEC’s website at www.sec.gov. Forward-looking statements are made as of the date of this press release, and except as provided by law BiomX expressly disclaims any obligation or undertaking to update forward-looking statements.
