## About

Founded in 2020 and based in Victoria, Australia, Ena Respiratory Pty Ltd engages in the research and development of solutions for the treatment and prevention of respiratory infections. Dr. Christophe Demaison is leading the firm as CEO as of 2024. In October 2025, Ena Respiratory Pty Ltd raised AUD 34 million in series B funding from new investor Gates Family Foundation. Returning investors Flu Lab, Brandon Capital Partners, Uniseed, and Stoic Venture Capital also participated in the round. The company offers a nasal innate immune regulator to mitigate the consequences of a viral respiratory illness. The company's lead product, INNA-051, is currently in clinical development. This nasal spray is designed to help the innate immune response to respiratory viruses, particularly in high-risk individuals such as those with COPD, asthma, and other comorbidities. The company plans to utilize the October 2025 funding to advance the Phase II clinical trials of INNA-051, a dry powder nasal spray designed to target multiple viruses.
