BiomX Announces Positive Topline Results from Phase 2 Trial Evaluating BX211 for the Treatment of Diabetic Foot Osteomyelitis (DFO)

BiomX Announces Positive Topline Results from Phase 2 Trial Evaluating BX211 for the Treatment of Diabetic Foot Osteomyelitis (DFO)

  • BX211 was safe and well-tolerated
  • BX211 produced sustained and statistically significant1 Percent Area Reduction (PAR) of ulcer size (p = 0.046 at week 12; p=0.052 at week 13), with a separation from placebo starting at week 7 and a difference greater than 40% by week 10
  • Compared to placebo, BX211 also produced statistically significant1 improvements in both ulcer depth at week 13 (in patients with ulcer depth defined as bone at baseline) (p=0.048), and in reducing the expansion of ulcer area (p=0.017).
  • BiomX is planning for a Phase 2/3 trial of BX211, pending U.S. Food and Drug Administration (FDA) feedback

The Company will host a conference call and webcast today at 9:00 AM ET, followed by a Key Opinion Leader (KOL) event on April 3, 2025, at 11:00 AM ET to discuss the results

NESS ZIONA, Israel, March 31, 2025 (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 announced positive, topline safety and efficacy results from the Company’s DFO Adaptive Novel Care Evaluation (DANCE™) Phase 2 trial evaluating its BX211 phage treatment for DFO associated with Staphylococcus aureus (S. aureus). The findings demonstrated BX211 to be safe and well-tolerated and that patients receiving BX211 exhibited statistically significant1 and sustained reduction of ulcer size (PAR) (p = 0.046 at week 12; p=0.052 at week 13), with a separation from placebo starting at week 7 and a difference greater than 40% by week 10. In addition, BX211 also produced statistically significant1 improvements in both ulcer depth at week 13 (in patients with ulcer depth defined as bone at baseline, ulcer depth was classified according to deepest tissue involved as measured by swab) (p=0.048), and in reducing the expansion of ulcer area (p=0.017). Over the 12-week treatment period, all patients (treatment and placebo) were treated in accordance with standard of care, including with systemic antibiotic therapy as appropriate. Following the successful Phase 2 readout of BX211, the Company is planning for a Phase 2/3 trial, pending discussions and feedback from the U.S Food and Drug Administration.

"We believe these data represent one of the strongest demonstrations to date of the therapeutic potential of phage therapy. We are grateful to all the patients who participated, and the treating teams who enrolled patients into the study, as well as the continued and ongoing support from the U.S. Defense Health Agency (DHA) for this program,” said Jonathan Solomon, BiomX’s Chief Executive Officer. “Today, 30-40% of DFO cases lead to lower extremity amputations related to serious bacterial infections, accounting for the majority of the 160,000 lower limb amputations in diabetic patients each year in the United States. Based on the results announced today, we believe BiomX’s novel phage therapy approach has the potential to help address the major unmet need in DFO. Moreover, in an era of modern conflict and rising antibiotic-resistant wounds, the need for innovative wound care solutions underscores the broader relevance of this program beyond DFO. BiomX is dedicated to the advancement of phage therapy, which we believe holds promise in redefining the treatment of chronic infections.”

“Phage therapy has a critical role to play in treating infections where antibiotic resistance has emerged or existing treatments have underperformed,” said Dr. Robert T. “Chip” Schooley, M.D., Distinguished Professor of Medicine, Division of Infectious Diseases and Global Public Health and Co-Director, Center for Innovative Phage Applications and Therapeutics at the University of California, San Diego. “The promising topline data in this trial provide an important inflection point for this approach and its potential to address the most challenging infections.”

“Diabetic foot infections are often a complex and difficult-to-treat consequence of diabetes, leading to serious adverse effects on patient quality of life,” said Dr. Benjamin A. Lipsky, M.D., FACP, FIDSA, FRCP (London), FRCPS (Glasgow), Professor of Medicine Emeritus at University of Washington, Seattle. “The most serious and feared complication of DFO is lower extremity amputation, which is associated with a five-year mortality rate of about 50%. With the progress seen so far and given the improved ulcer healing seen in this study, BX211 may have the potential to reduce amputations. BX211 is a program to watch closely as it progresses into more advanced clinical studies.”

Summary of Phase 2 BX211 Results

BiomX’s Phase 2 trial is a randomized, double-blind, placebo-controlled, multi-center study investigating the safety, tolerability, and efficacy of BX211 for individuals with DFO associated with S. aureus. The study enrolled a total of 41 patients randomized for treatment at a 2:1 ratio, 26 of whom received intravenous (IV) and topical administration of BX211 on week 1 followed by a topical weekly dose through week 12, while 15 patients were assigned to the placebo arm. Over the 12-week treatment period, all subjects (treatment and placebo) were also treated in accordance with standard of care, including with systemic antibiotic therapy as appropriate. A readout of study results at week 13 evaluated healing of the wound associated with osteomyelitis. The primary efficacy endpoint was PAR of study ulcer through week 13. Study design was guided in part by experience with numerous compassionate cases using phage therapy for the treatment of DFO and osteomyelitis.

The topline Phase 2 results included:

  • BX211 was found to be safe and well-tolerated.
  • BX211 produced sustained and statistically significant1 PAR of ulcer size (p = 0.046 at week 12; p=0.052 at week 13), with a separation from placebo (standard of care) starting at week 7 and a difference greater than 40% by week 10.
  • BX211 produced statistically significant1 improvements in both ulcer depth at week 13 (in patients with ulcer depth defined as bone at baseline) (p=0.048), and in reducing the expansion of ulcer area (p=0.017), compared to placebo.
  • BX211 demonstrated favorable trends compared to placebo across several additional clinical parameters, including: proportion of visits with no clinical evidence of infection; evidence of resolving DFO by MRI/X-ray at week 12; proportion of patients with abnormal C-Reactive Protein at baseline that achieved a reduction of CRP of at least 50% at any point in the study; and greater Wagner scale improvement2.
  • Through week 13, BX211 demonstrated comparable efficacy against both Methicillin-susceptible and resistant strains, as well as against high and low biofilm producers—consistent with the orthogonal mechanism of phage therapy to antibiotics and its inherent anti-biofilm capabilities.

BiomX expects to present additional data from the Phase 2 study at upcoming scientific conferences.

BiomX management will host a conference call and webcast today at 9:00 AM ET to review the topline Phase 2 trial results, accompanied by a slide deck presentation, which will be available on the Company's website and filed via Form 8-K.
