Aytu BioPharma Announces Issuance of First U.S. Patent Supporting Healight Ultraviolet-A Respiratory Catheter

ENGLEWOOD, CO / ACCESSWIRE / November 23, 2021 / Aytu BioPharma, Inc. (NASDAQ:AYTU), a specialty pharmaceutical company focused on commercializing novel therapeutics and consumer healthcare products, announced that today the United States Patent and Trademark Office (USPTO) has issued a U.S. patent for the Healight™ ultraviolet-A light-based respiratory catheter. U.S. Patent Number 11,179,575, titled "Internal Ultraviolet Therapy," is the first issued patent protecting the Healight investigational device and covers methods of treating a patient for an infectious condition inside the patient's body through the insertion of a UV-light-emitting delivery tube inside a respiratory cavity of the patient at specific UV-A light wavelengths. The term of this patent extends to August of 2040.

"This is an important milestone in the development of the Healight medical device platform and provides for broad protection for the device platform for use as a respiratory catheter to treat infectious conditions," stated Josh Disbrow, chief executive officer of Aytu BioPharma. "Importantly, given the broad patent claim around use of the device within the full respiratory cavity, this enables potential function and clinical use of Healight beyond endotracheal application and may enable use through nasal or upper respiratory insertion. Our near-term development plan remains focused on developing Healight for severe respiratory infections - and specifically SARS-CoV-2 - affecting severely ill, ventilated patients, and we're looking forward to advancing Healight development and progressing our sham-controlled study in Barcelona, Spain."

Healight is an investigational medical device technology employing proprietary methods of administering intermittent ultraviolet (UV)-A light via a novel respiratory medical device. This patent was issued to Cedars-Sinai Medical Center, from which Aytu BioPharma has an exclusive worldwide license for all respiratory applications of the UV-A light-based technology. Proof of concept clinical findings demonstrated significant reductions in SARS-CoV-2 viral load and improvement in clinical outcomes in a small number of mechanically ventilated COVID-19 patients. Earlier published preclinical findings indicated the technology's significant impact on eradicating a wide range of viruses and bacteria, inclusive of human coronavirus.
