First Mexican Hospital Steriwave Deployment

Ondine Biomedical Inc. (AIM: OBI) announces the American British Cowdray ("ABC") Medical Center in Mexico City will begin piloting Steriwave® nasal photodisinfection system in September. This marks the first hospital deployment of Steriwave in Mexico and will target the reduction of surgical site infections (SSIs) and healthcare-associated infections (HAIs) in orthopedic and neurosurgery patients.

With a population of approximately 132 million, Mexico's healthcare system is anchored by its private sector, which comprises approximately 3,000 private hospitals which perform around 25% of all surgeries annually. This private sector is crucial for high-income citizens and the thriving medical tourism industry, which attracts over 1.3 million international patients annually. A key challenge facing this sector is the high rate of surgical site infections (SSIs), which are nearly double those in the U.S. This issue is compounded by rising antimicrobial resistance (AMR), making advanced infection control a critical priority for hospitals, surgery centers, and clinics that serve this valuable market.

Carolyn Cross, CEO of Ondine, said:

"The Mexican market is a key pillar of our long-term strategic growth plans, and we are thrilled to partner with a world-class institution in ABC Medical Center. Their dedication to clinical excellence and patient safety makes them the ideal pilot partner for Steriwave's initiation in Mexico. This collaboration is a vital step in introducing our validated, non-antibiotic solution to a large market where combatting rising multidrug resistance is a top priority."

• Roxana Trejo Gonzalez, Director of Infection Control at the ABC Medical Center, President of the Mexican Association for the Study of Nosocomial Infections (AMEXPE) and Co-founder of the Latin American Association for Infection Control (ASLACI) commented:

"Piloting Steriwave as a first in Mexico reflects our commitment to adopting evidence-based interventions against antimicrobial resistance. Reducing nasal pathogen load is a crucial step in preventing SSIs and protecting our local and international patients."

Steriwave has been deployed in leading hospitals in Canada, the UK, and other jurisdictions, with studies showing significant reductions in HAIs and no evidence of microbial resistance development. Steriwave is a non-antibiotic, light-activated therapy that decolonizes the nasal passages, a primary reservoir for multidrug-resistant organisms. The procedure involves applying a proprietary photosensitizer into the nares, followed by illumination with red light. This photochemical reaction generates singlet oxygen, rapidly inactivating bacteria, viruses, and fungi, without contributing to AMR.
