Axelia Oncology Pty Ltd. was spun out of Ena Respiratory Pty. Ltd., which developed a series of synthetic Toll-like receptor (TLR) 2/6 agonists for nasal delivery to treat respiratory infections, including influenza and SARS-CoV-2. Although the pegylated TLR 2/6 agonist, INNA-051, was initially focused on antiviral activity, the company discovered that it also worked in oncology models, and Axelia was spun out to focus on oncology, CEO Phil Kearney told BioWorld.
