Ondine’s Photodisinfection Technology Being Developed To Treat Chronic Sinusitis

Photodisinfection is a highly effective antimicrobial therapy involving non-thermal light and a topically placed photosensitizer. It is currently being used for the treatment of oral infections and nasal decolonization of MRSA and S. aureus. Photodisinfection is also being currently used for the treatment of endotracheal tube biofilms to prevent ventilator associated pneumonia. One of the areas of medical need identified for photodisinfection is for the treatment of chronic sinusitis that has failed surgical and medical therapies. It is estimated that there are more than 500,000 of these people suffering in the US alone, and this number grows by 10% annually.

Polymicrobial biofilms, many of them antibiotic resistant, have been significantly implicated in the etiology of this chronic indolent disease process and its associated inflammatory processes.  Preclinical studies we have conducted demonstrate the effectiveness of photodisinfection to selectively photoeradicate a broad spectrum of biofilm micoorganisms, including antibiotic resistant S. aureus, P. aerugenosa and fungal species, without causing injury to tissue or mucosa.

Ondine Study Shows Reduction of Endotracheal Tube Biofilm Using Photodisinfection

Ventilator-associated pneumonia is one of the most common and deadliest forms of healthcare-associated infections.  In the U.S alone, more than one million patients in healthcare facilities require mechanical ventilation every year. Up to 1 in 4 of these patients are reported to develop ventilator-associated pneumonia and up to half of them will die.1

Antimicrobial photodynamic therapy (aPDT), commonly known as Photodisinfection, is a non-invasive technique that used to study the reduction of biofilm in the lumen of an endotracheal tube. When patients undergo mechanical ventilation, an endotracheal tube is inserted into their throat to assist with breathing. This tube has long been recognized as a major factor in a patient’s risk for developing biofilm infections. For patients that require mechanical ventilation, such as those in ICUs, the biofilm can dislodge from the endotracheal tube and enter the lungs directly, often resulting in difficult-to-treat pneumonia.

Ondine To Launch Ventilator-Associated Pneumonia (VAP) Photodisinfection Clinical Study

We are thrilled to announce that the FDA has approved a human clinical study to investigate the use of photodisinfection to prevent ventilator-associated pneumonia (VAP). VAP occurs when a lung infection develops in a patient ventilated with an endotracheal tube and continues to be the #1 cause of healthcare-associated infections in intensive care units. In the U.S alone, more than 1.3 million patients are mechanically ventilated every year. Of these patients, 10%-20% will develop ventilator-associated pneumonia, and up to half of them will die.

“A successful VAP study would represent a key step towards the commercialization of this new application of photodisinfection which utilizes Ondine’s patented technology and products…(our technology) has been proven to be highly effective at eliminating biofilms in ex vivo models, it is therefore ideally suited for the elimination of endotracheal tube biofilms resulting in the prevention of VAP” says Carolyn Cross, Chairman & CEO of Ondine.
