Analysis of Part 2 data from Phase 1b/2a trial of BX004 ongoing; Company expects to announce Part 2 data later this month

BX004 received FDA Fast Track designation in August

Part 1 data recently presented at the North American Cystic Fibrosis Conference (NACFC)

CAMBRIDGE, Mass. and NESS ZIONA, Israel, Nov. 14, 2023 (GLOBE NEWSWIRE) -- BiomX Inc. (NYSE: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 third quarter ended September 30, 2023.

"Thanks to the continued execution of our clinical team, we are now analyzing data from Part 2 of the Phase 1b/2a trial of BX004 and expect to announce the results later this month," said Jonathan Solomon, Chief Executive Officer of BiomX. "I am also pleased to note that the positive data from Part 1 of our trial has been well received by physicians and patient advocacy groups at several prominent medical meetings, reflecting the need to develop innovative new therapies for combating these persistent and deadly lung infections. In addition, the U.S. Food and Drug Administration recently granted Fast Track designation for BX004, further underscoring the potential of this promising program.

"As a reminder, Part 2 of the trial is evaluating BX004 in a larger number of cystic fibrosis patients who are dosed twice a day and over a longer, 10-day treatment period compared to Part 1 of the trial. Part 2 of the trial will provide additional clinical data on safety and reduction in bacterial burden, along with other exploratory clinical endpoints, all of which will help us guide our clinical development strategy for the program. In light of the expected readout of the Part 2 data, we are forgoing our usual earnings call and will instead host a conference call and webcast following the release of the Part 2 data."

Clinical Program Updates

Cystic Fibrosis (BX004)

In October 2023, BiomX announced the completion of patient dosing in Part 2 of the Phase 1b/2a trial evaluating the Company's novel phage cocktail, BX004, for the treatment of chronic pulmonary infections caused by Pseudomonas aeruginosa (or P. aeruginosa) in patients with cystic fibrosis ("CF"). The Company expects data from Part 2 will be announced later this month.

In October 2023, BiomX presented data from Part 1 of its Phase 1b/2a trial evaluating BX004 for the treatment of chronic pulmonary infections caused by P. aeruginosa (PsA) bacteria in patients with CF at the North American Cystic Fibrosis Conference (NACFC). Highlights from the Part 1 data, which were initially reported in February 2023 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)

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
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 trial 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 trial evaluates the safety and efficacy of BX004 in at least 24 CF patients randomized to a treatment or placebo cohort in a 2:1 ratio.

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.

Third Quarter 2023 Financial Results

Cash balance, short-term deposits and restricted cash as of September 30, 2023, were $23.4 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 $5.6 million for the three months ended September 30, 2023, compared to $3.5 million for the same period in 2022. The increase was primarily attributed to an increase in expenses related to conducting the clinical trial of the Company's CF product candidate, BX004. Such increase was partially offset by reduced salaries and related expenses and stock-based compensation expenses that resulted from a workforce reduction, as well as the appreciation of the U.S. dollar against the NIS, which led to reduced salaries and related expenses in the Company's Israeli subsidiary.
General and administrative expenses were $2.2 million for the three months ended September 30, 2023, compared to $2.6 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, as well as a decrease in professional services expenses.
Net loss for the third quarter of 2023 was $7.9 million, compared to $6.8 million for the same period in 2022.
Net cash used in operating activities for the nine months ended September 30, 2023, was $15.0 million, compared to $21.9 million for the same period in 2022.

Given the close proximity between the Company's third quarter earnings report and the expected announcement of the Part 2 data from the Phase 1b/2a trial, BiomX management will forgo holding a call to review its third quarter 2023 earnings and will instead host a conference call and webcast following the release of the Part 2 data.
