BiomX Reports Second Quarter 2023 Financial Results and Provides Business Update

Patient Screening Completed in Part 2 of Phase 1b/2a Trial of BX004 with patient enrollment expected to exceed original estimates

FDA grants BX004 Fast Track designation

Initial Data from Part 2 Now Expected inNovember 2023

Company Will Host a Conference Call and Webcast Today at 8:00 am ET

CAMBRIDGE, Mass. and NESS ZIONA, Israel, Aug. 09, 2023 (GLOBE NEWSWIRE) -- BiomX Inc. (NYSE American: PHGE) (“BiomX” or the “Company”), a clinical-stage company advancing novel natural and engineered phage therapies that target specific pathogenic bacteria, today reported financial results and provided a business update for the second quarter ended June 30, 2023.

“Our BX004 clinical program in cystic fibrosis (“CF”) continues to build significant momentum,” said Jonathan Solomon, Chief Executive Officer of BiomX. “We recently completed patient screening in Part 2 of our ongoing Phase 1b/2a trial with patient enrollment expected to exceed original estimates, which reflects continued execution by our clinical team and a growing awareness within the CF patient community of the BX004 program. I am also pleased to announce that BX004 just received Fast Track designation from the FDA, which provides further recognition that our BX004 program is addressing one of the most serious and challenging unmet medical needs facing the CF community.

“In June, we presented our positive Part 1 results at the recent European Cystic Fibrosis Conference (“ECFC”) meeting, which highlighted the excellent safety of BX004 along with its notable activity in reducing P. aeruginosa bacteria burden. In Part 2, we are testing BX004 in a larger number of CF patients who are dosed twice a day and over a longer, 10-day treatment period compared to Part 1. Part 2 of the study will provide additional data on safety and reduction in bacterial burden, along with other exploratory clinical endpoints. Based on our current estimates, we now believe the Part 2 data analysis will take an additional 4-6 weeks to complete. We therefore expect to report initial results from Part 2 in November 2023.”

Clinical Program Updates

Cystic Fibrosis (BX004)

• In August 2023, the U.S. Food and Drug Administration (“FDA”) granted BX004 Fast Track designation for the treatment of chronic respiratory infections caused by Pseudomonas aeruginosa (PsA) bacterial strains in patients with CF. The FDA’s Fast Track designation is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and address significant unmet medical needs. The FDA defines addressing a significant unmet medical need as providing a therapy where none exists or providing a therapy which may be potentially better than available therapies. The benefits of Fast Track designation include but are not limited to early and frequent communication with the FDA throughout the entire drug development and review process. In addition, a drug with Fast Track designation is eligible for rolling submission and priority review of its Biologics License Application and/or New Drug Application. These assure that questions and issues are resolved quickly, often leading to earlier drug approval and access by patients.¹
• In June 2023, during the Late-Breaking Science Session at the 46th ECFC, BiomX presented positive results from Part 1 of the Phase 1b/2a trial evaluating BX004 for the treatment of chronic pulmonary infections caused by P. aeruginosa bacteria in patients with CF. Highlights from the Part 1 data, which were initially reported in February 2023, were also presented at a poster session during the ECFC meeting (link to poster) and included:
  
  • No safety events related to treatment with BX004
  • Mean P. aeruginosa colony forming units (CFU) at Day 15 (compared to baseline) were reduced by more than 90%: -1.42 log10 CFU/g (BX004) vs. -0.28 log10 CFU/g (placebo). This reduction occurred in the presence of standard of care inhaled antibiotics
  • Phages were detected in the sputum of all patients treated with BX004 during the dosing period, including in several patients up to Day 15 (one week after end of therapy); no phages were detected in patients receiving placebo
  • There was no emerging bacterial resistance to BX004 during or after treatment with BX004
  • As expected, likely due to the short course of therapy, there was no detectable effect on % predicted FEV1 (First-second Forced Expiratory Volume)
    
• BX004 is being developed for the treatment of chronic respiratory infections caused by P. aeruginosa, a main contributor to morbidity and mortality in patients with CF. The Phase 1b/2a trial is composed of two parts. Part 1 of the study evaluated the safety, pharmacokinetics, and microbiologic/clinical activity of BX004 in nine CF patients in a single ascending dose and multiple dose design. Part 2 of the study will evaluate the safety and efficacy of BX004 in at least 24 CF patients randomized to a treatment or placebo cohort in a 2:1 ratio. Results from Part 2 of the trial are expected in November 2023.
• As previously announced, BiomX has received a Therapeutics Development Award of $5 million from the Cystic Fibrosis Foundation. The award was structured as an equity investment in which the Cystic Fibrosis Foundation purchased $5 million of BiomX common stock across two separate tranches.

Atopic Dermatitis (“AD”) (BX005)

• The Company is collaborating with Maruho Co. Ltd., a leading dermatology-focused pharmaceutical company in Japan, supporting a range of pre-clinical activities to move this program forward and working on evaluating timelines for a clinical trial.

RECENT CORPORATE HIGHLIGHTS

• On May 12, 2023, the Company announced the appointments of Jason M. Marks and Michael E. Dambach, CFA to its Board of Directors. Mr. Marks most recently served as Executive Vice President, Chief Legal and Compliance Officer & Corporate Secretary/Senior Advisor with Amarin Corporation plc, and Mr. Dambach serves as Vice President and Treasurer of Biogen Inc.
• On May 5, 2023, the Company announced the second closing of its $7.5 million private placement investment (“PIPE”). The Company expects to use the aggregate net proceeds from the PIPE, together with existing cash and cash equivalents, to fund clinical development of BX004 for the treatment of lung infections in patients with CF, the development of other phage therapy programs and research activities, as well as working capital and other general corporate purposes.

Second Quarter 2023 Financial Results

• Cash balance, short-term deposits and restricted cash as of June 30, 2023, were $30.7 million, compared to $34.3 million as of December 31, 2022. The decrease was primarily due to net cash used in operating activities. The Company estimates its cash runway is sufficient to fund operations into the third quarter of 2024.
• Research and development (“R&D”) expenses, net were $3.8 million for the three months ended June 30, 2023, compared to $4.6 million for the same period in 2022. The decrease was primarily attributed to reduced salaries and related expenses and stock-based compensation expenses that resulted from a reduction in workforce, as part of a corporate restructuring the Company announced in May 2022 (the “Corporate Restructuring”); as well as deprioritizing pre-clinical and clinical activities related to the Company’s AD product candidate, BX005, and higher proceeds from collaboration agreements in the 2023 period. These were partially offset by expenses related to conducting the Phase 1b/2a clinical trial of the Company’s CF product candidate, BX004.
• General and administrative expenses were $2.3 million for the three months ended June 30, 2023, compared to $2.4 million for the same period in 2022. The decrease primarily resulted from a reduction in the premium for the Company’s directors’ and officers’ insurance policy.
• Net loss for the second quarter of 2023 was $6.4 million, compared to $7.5 million for the same period in 2022.
• Net cash used in operating activities for the six months ended June 30, 2023, was $9.1 million, compared to $16.4 million for the same period in 2022.
