Following merger with Adaptive Phage Therapeutics in March, combined company reports funding sufficient to support important data readouts for lead clinical programs in 2025

Company will host a conference call and webcast today at 8:00 am ET

GAITHERSBURG, Md. and NESS ZIONA, Israel, May 21, 2024 (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 business and program updates for the first quarter ended March 31, 2024. BiomX is announcing merged financial reporting for the first time following the closing of its merger with Adaptive Phage Therapeutics, Inc. (“APT”) in March 2024 and a concurrent $50 million private placement.

Based on a cash balance, short term deposits and restricted cash of $44.1 million as of March 31, 2024, BiomX estimates it currently has a cash runway through the fourth quarter of 2025. The Company anticipates data readouts for both of its lead programs in 2025: Topline results (through Week 13) for the Phase 2 study of BX211, a personalized phage treatment for the treatment of diabetic foot osteomyelitis (“DFO”) associated with Staphylococcus aureus (S. aureus), are expected in the first quarter of 2025, and Phase 2b trial results for BX004, a fixed multi-phage cocktail for the treatment of cystic fibrosis (“CF”) patients with chronic pulmonary infections caused by Pseudomonas aeruginosa (P. aeruginosa), are expected in the third quarter 2025.

“With the recent merger with APT and our private placement, we believe we have entered into a new era for BiomX as a leading phage company focused on treating harmful bacteria underlying serious chronic infections,” said Jonathan Solomon, Chief Executive Officer of BiomX. “BiomX is rapidly advancing a pipeline with two lead candidates, both expecting Phase 2 readouts next year. For BX004, we have demonstrated for the first time in a randomized controlled study that a subset of CF patients converted to sputum culture negative for P. aeruginosa after only 10 days of treatment with BX004¹. These findings were showcased in a presentation that was selected as a ‘Top Poster’ at last month’s ESCMID Global Congress. With the APT merger, we now have added BX211, a promising treatment for DFO, advancing in a Phase 2 study with more than 70% of patients enrolled. On the business side, we have gained important and accredited life sciences investors, another important validation for the potential of phage therapy as a new therapeutic modality and the strength of our lead candidates. We believe these and other recent achievements are bringing us closer to our goal of meeting unmet patient needs through advancement of our phage-based therapies.”

Business Update

• In March 2024, the Company announced the closing of its merger with APT and concurrent closing of a private placement financing with $50 million of gross proceeds led by top institutional healthcare investors, including affiliates of Deerfield Management and the AMR Action Fund, and additional investors including the Cystic Fibrosis Foundation, OrbiMed, and Nantahala Capital Management. The net proceeds from the private placement are primarily being used to further advance BiomX’s lead product candidates, BX004 and BX211.

Clinical Program Updates

Cystic Fibrosis (BX004)

• In January 2024, the Company announced that BX004 was granted Orphan Drug Designation by the United States Food and Drug Administration (“FDA”), for the treatment of chronic pulmonary infection caused by P. aeruginosa in patients with CF.
• In April 2024, the Company presented at this year’s European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Global Congress positive safety and efficacy results from 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 P. aeruginosa in CF patients. BiomX’s poster was selected as a “Top Poster”, ranking it among the 1-2% of top-rated abstracts in the category submitted and accepted at the ESCMID Global Congress.
• Highlights from the Part 2 data of the Phase 1b/2a study included:
  • Study drug was safe and well-tolerated, with no related SAEs (serious adverse events) or related APEs (acute pulmonary exacerbations) to study drug.
  • In the BX004 arm, 3 out of 21 (14.3%) patients converted to sputum culture negative for P. aeruginosa after 10 days of treatment (including 2 patients after 4 days) compared to 0 out of 10 (0%) in the placebo arm¹. BX004 vs. placebo showed a clinical effect in a predefined subgroup of patients with reduced baseline lung function (FEV1<70%). Difference between groups at Day 17: relative FEV1 improvement of 5.67% (change from baseline +1.46 vs. -4.21) and +8.87 points in CFQR respiratory symptom scale (change from baseline +2.52 vs. -6.35).

Diabetic Foot Osteomyelitis (BX211)

• BX211 is a personalized phage treatment that BiomX is now developing following the merger with APT. BX211 is being developed for the treatment of DFO associated with S. aureus. The safety, tolerability, and efficacy of BX211 is currently being evaluated in a randomized, double-blind, placebo-controlled, multi-center Phase 2 trial for subjects with DFO. Target enrollment for the study is 45 patients, and to date, more than 70% of the patients have been enrolled. Initial topline results of the Phase 2 trial are expected in the first quarter of 2025. Study design was guided in part by experience with numerous compassionate cases using phage therapy for the treatment of DFO and Osteomyelitis.

First Quarter 2024 Financial Results

The financial results of the first quarter of 2024 include the consolidation of the financial results of APT from the closing date of the merger and the accounting implications derived from the merger and the concurrent private placement.

• Cash balance, short-term deposits and restricted cash as of March 31, 2024, were $44.1 million, compared to $30.3 million as of March 31, 2023. The increase was primarily due to the private placement, which was partially offset by net cash used in operating activities and the repayment of a debt facility in March 2024. The Company estimates its cash, cash equivalents and short-term deposits are sufficient to fund its operations through the fourth quarter of 2025.
• Research and development expenses, net were $4.1 million for the first quarter of 2024, compared to $4.6 million for the first quarter of 2023. The decrease is primarily due to the completion of the CF clinical trial, and was partially offset by lower grants payments from the Israeli Innovation Authority and R&D expenses related to APT that were incurred after the merger.
• General and administrative expenses were $2.7 million for the first quarter of 2024, compared to $1.6 million for the first quarter of 2023. The increase primarily resulted from expenses related to the merger with APT and the concurrent private placement.
• Net loss was $17.3 million for the first quarter of 2024, compared to $6.4 million for the first quarter of 2023. The increase is mainly due to changes in fair value of private placement warrants that were issued in this quarter.
• Net cash used in operating activities for the three months ended March 31, 2024, was $11.4 million, compared to $5.0 million for the same period in 2023.

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 trial 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 function (baseline FEV1<70%).

BiomX expects to initiate a randomized, double blind, placebo-controlled, multi-center Phase 2b trial in CF patients with chronic P. aeruginosa pulmonary infections in the fourth quarter of 2024. The trial 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 trial 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. Trial results are expected in the third quarter 2025. The FDA has granted BX004 Fast Track designation and Orphan Drug Designation.

About BX211
BX211 is a personalized phage treatment 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 trial 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.
