AIM Rule 26

Ondine is dedicated to the development of non-antibiotic, antimicrobial therapies to address the urgent need for solutions to a broad spectrum of drug-resistant infections.

Our Vision

Our Vision
A world free from untreatable infections

Our Mission

Enabling worldwide access
to the power of photodisinfection

Our Platform

Our proprietary photodisinfection kills bacteria, viruses, and fungi (including antibiotic resistant strains) in minutes without the need for testing or screening and without the risk of incurring resistance.

Ondine Biomedical was incorporated in British Columbia, Canada, and its main country of operation is Canada. As such, the rights of shareholders may be different from the rights of shareholders in a UK incorporated company. The information below is disclosed for the purposes of AIM Rule 26.

Ondine Biomedical Inc. is a life sciences company at the forefront of development of photodisinfection-based therapies to address the large and growing need for solutions to a broad spectrum of infections.

We have created a novel, patented platform technology, called “photodisinfection”, to help prevent and treat serious infections, including those caused by existing, emerging, and antimicrobial-resistant pathogens. We are focused on solutions that address significant needs, are easy to deploy, are environmentally safe, provide substantial public health benefits, and cost a fraction of the infections they target.

Our pipeline of products, in various stages of development, are based on our patent protected photodisinfection platform. The pipeline includes treatment of chronic rhinosinusitis, decolonization of infections in burns and wounds, disinfection of endotracheal tubes to reduce the incidence of ventilator-associated pneumonia and most recently, the development of topical antiviral therapy for the upper respiratory tract to reduce viral titres and transmission of respiratory viruses (e.g., SARS-CoV-2, influenza, RSV, etc.). Our technology is approved in a number of jurisdictions and has been awarded the CE mark, as well as Qualified Infectious Disease Product and Fast Track status in the U.S. by the FDA.
