Conference call today at 9:00 a.m. EST

CAMBRIDGE, Mass. and NESS ZIONA, Israel, March 06, 2024 (GLOBE NEWSWIRE) — BiomX Inc. (NYSE American: PHGE) (together with its subsidiaries and/or associates, “BiomX”), a clinical-stage company advancing novel natural and engineered phage therapies that target specific pathogenic bacteria, today announced that it has entered into a definitive merger agreement with Adaptive Phage Therapeutics, Inc. (“APT”), a U.S.-based privately-held, clinical-stage biotechnology company pioneering the development of phage-based therapies to combat bacterial infections (the “Acquisition”). Immediately after the effective time of the Acquisition, and before giving effect to the concurrent private placement the former stockholders of BiomX will own approximately 55% and the former stockholders of APT will own approximately 45% of the consolidated entity of BiomX and APT. The Acquisition is expected to close within the next 30 days, subject to the satisfaction of the closing conditions described in the definitive merger agreement. Concurrently with entering into the definitive merger agreement, BiomX entered into a definitive purchase agreement for the sale of shares of newly created non-voting convertible preferred stock (“Series X Preferred Stock”) and warrants to purchase shares of BiomX common stock in a private placement to certain institutional accredited investors led by affiliates of Deerfield Management Company and the AMR Action Fund, and additional investors including the Cystic Fibrosis Foundation, OrbiMed and Nantahala Capital. The private placement is expected to result in gross proceeds to BiomX of $50 million before deducting placement agent and other offering expenses. The proceeds from the private placement are expected to provide funding through the results from a planned Phase 2b trial that will evaluate BiomX’s lead product candidate, BX004, for the treatment of chronic pulmonary infections caused by Pseudomonas aeruginosa (P. aeruginosa) in CF patients expected in the third quarter of 2025 and Phase 2 results from APT’s clinical-stage product candidate, now named BX211, for the treatment of Staphylococcus aureus (S. aureus) infections in DFO patients expected in the first quarter of 2025. The private placement is expected to close substantially concurrently with, and subject to the closing of, the Acquisition.

“BiomX’s acquisition of APT will create a leading phage company with diverse technologies and an advanced clinical pipeline,” said Jonathan Leff, Partner and Chairman of the Deerfield Institute at Deerfield Management. “With important data readouts for two programs expected in 2025, the funding from this transaction is designed to provide multiple opportunities to create stockholder value by reaching critical inflection points in each program’s clinical development.”

“Today’s announcement sends a clear vote of confidence from leading biotechnology investors who led this transaction that phage technology holds significant potential to treat serious infections with significant unmet need and limited treatment options,” said Jonathan Solomon, Chief Executive Officer of BiomX. “In the case of CF, BX004 has the potential to improve lung function in patients with chronic and potentially deadly pulmonary infections.”

“APT’s phage therapy for DFO holds the potential to prevent amputations associated with intractable infections that have penetrated into the bone in patients with diabetic foot ulcers,” said Greg Merril, Founder and Board Director of APT. “With the combined intellectual and financial resources coming from this acquisition, we now have a clear line of sight towards applying this ground-breaking technology to reach multiple data readouts in CF and DFO over the next 12-24 months.”

Management and Organization
BiomX will continue to be led by its current management team, with the addition of Michael Billard from APT as General Manager, U.S. Following the transaction, the BiomX board of directors will be comprised of Dr. Russell Greig, Chair of the Board of Directors, and the following members of the board of directors – Dr. Jesse Goodman, Jonathan Leff, Dr. Alan Moses, Greg Merril, Eddie Williams and Jonathan Solomon, BiomX’s Chief Executive Officer.

Conference Call Dial-In Information:

About BX004
BiomX is developing BX004, a fixed multi-phage cocktail, for the treatment of CF patients with chronic pulmonary infections caused by P. aeruginosa, a main contributor to morbidity and mortality in patients with CF. In November 2023, BiomX announced positive topline results from Part 2 of the Phase 1b/2a study where BX004 demonstrated improvement in pulmonary function associated with a reduction in P. aeruginosa burden compared to placebo in a predefined subgroup of patients with reduced lung function¹.

BiomX expects to initiate a randomized, double blind, placebo-controlled, multi-center Phase 2b study in CF patients with chronic P. aeruginosa pulmonary infections in the fourth quarter of 2024. The study is designed to enroll approximately 60 patients randomized at a 2:1 ratio to BX004 or placebo. Treatment is expected to be administered via inhalation twice daily for a duration of 8 weeks. The study is designed to monitor the safety and tolerability of BX004 and is designed to demonstrate improvement in microbiological reduction of P. aeruginosa burden and evaluation of effects on clinical parameters such as lung function measured by FEV1 and patient reported outcomes. Study results are expected in the third quarter 2025. The U.S. Food and Drug Administration (“FDA”) has granted BX004 Fast Track designation and Orphan Drug Designation.

About BX211
BX211 is a personalized phage treatment developed by APT for the treatment of DFO associated with S. aureus. The personalized phage treatment tailors a specific phage selected from a proprietary phage-bank according to the specific strain of S. aureus biopsied and isolated from each patient. DFO is a bacterial infection of the bone that usually develops from an infected foot ulcer and is a leading cause of amputation in patients with diabetes.

The ongoing randomized, double-blind, placebo-controlled, multi-center phase 2 study investigating the safety, tolerability, and efficacy of BX211 for subjects with DFO associated with S. aureus is expected to enroll approximately 45 subjects randomized at a 2:1 ratio to BX211 or placebo. BX211 or placebo is designed to be administered weekly, by topical and IV route at Week 1 and by the topical route only at each of Weeks 2-12. Over the 12-week treatment period, all subjects are expected to continue to be treated in accordance with standard of care which will include antibiotic treatment as appropriate. A first readout of study topline results is expected at week 13 evaluating healing of the wound associated with osteomyelitis, followed by a second readout at week 52 evaluating amputation rates and resolution of osteomyelitis based on X-ray, clinical assessments, and established biomarkers (ESR and CRP). These readouts are expected in the first quarter of 2025 and the first quarter of 2026, respectively.

Safe Harbor
This press release 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 concerning BiomX, APT, the private placement, the Acquisition and other matters. These forward-looking statements include, but are not limited to: the expected consummation of the Acquisition; future expectations, plans and prospects for BiomX following the consummation of the Acquisition; the expected consummation of the concurrent private placement; the use of proceeds from the private placement and the sufficiency of BiomX cash resources; stockholder approval of the conversion of the Series X Preferred Stock and the exercise of the warrants; the milestones of BiomX; the projected cash runway of BiomX; the status and plans for clinical trials, including the timing of data; future product development; the potential market for phage therapies; and the potential commercial opportunity of BX004 and BX211. 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 discusses the safety, tolerability and efficacy of BX004 and its potential ability to treat CF patients, as well as the potential to advance the BX004 program to a larger, pivotal Phase 2b/3 trial, if such trial is initiated, including, among other things, timing, design, enrollment, regulatory approvals and funding of such trial, BiomX is making 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. In addition, past and current pre-clinical and clinical results, as well as compassionate use, are not indicative and do not guarantee future success of BiomX clinical trials. 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. Actual results and outcomes may differ materially from those indicated in the forward-looking statements, as a result of various important factors, including risks and uncertainties related to the ability to recognize the anticipated benefits of the Acquisition; the outcome of any legal proceedings that may be instituted against BiomX following the Acquisition and related transactions; the ability to obtain or maintain the listing of the common stock of BiomX on the NYSE American following the Acquisition; costs related to the Acquisition; 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; investigational review boards at clinical trial sites and publication review bodies with respect to our development candidates; our ability to obtain, maintain and enforce intellectual property rights for our platform and development candidates; our 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 29, 2023, 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.
