Ondine’s nasal photodisinfection therapy (APDT) improves short-term and long-term immune response while significantly reducing SARS-CoV-2 infectivity

The first randomized, placebo-controlled, single-blind clinical study of Steriwave™ nasal photodisinfection in 75 predominantly vaccinated COVID-19 patients has been published.

VANCOUVER, Canada, January 31, 2023--(BUSINESS WIRE)--The study, published in Frontiers in Cellular and Infection Microbiology,1 met its primary endpoint, with a highly significant decrease in viral infectivity recorded as early as two days after treatment (p<0.0001). By contrast, patients in the placebo control arm, who underwent simulated treatment without the active components being applied, were non-responsive (p=0.24). No serious adverse events were reported.

Steriwave therapy also significantly improved the immune-protective status of treated patients, as measured by PCR testing one week after treatment (over six times fewer PCR-positive patients compared to controls). These results were paralleled by significant improvement in the patient-reported symptoms of chest tightness and headache.

The study was conducted at the Clínica Universidad de Navarra, a tertiary teaching hospital in Pamplona, Spain during the highly contagious sixth Omicron outbreak in late 2021 and early 2022. Over 90% of the patients recruited into the study were fully vaccinated.
