Vasomune Therapeutics Announces Poster Presentation at the American Thoracic Society International Conference

Late-Breaking scientific poster at the American Thoracic Society Advances in Pulmonary Vascular Disease sessions will present AV-001 activity in SARS-CoV-2 Infection/COVID-19

Vasomune Therapeutics Inc., a clinical-stage biopharmaceutical company focused on the development of AV-001 for the treatment of diseases associated with vascular dysfunction, today announced that the Company will present a Late-Breaking scientific poster at the upcoming 2025 American Thoracic Society (ATS) International Conference taking place May 16-21, 2025, at the Moscone Center, San Francisco, CA.

Vasomune’s lead drug candidate AV-001 is a first-in-class fully synthetic PEGylated peptide targeting the Tie2 receptor. Activation of the Tie2 receptor plays a critical role in vascular stability, barrier integrity and endothelial quiescence, and has shown potential to benefit the prevention and treatment of acute respiratory distress syndrome (ARDS). Vasomune and co-development partner AnGes Inc., continue to advance AV001-004, the CDMRP-supported Phase 2a study of AV-001 in patients with bacterial and viral pneumonia.

Clinical and Scientific Sessions

• Date: May 21, 2025
• Presentation Time: 11:00 AM – 1:00 PM PT
• Location: Room 3009/3011 (West Building, Level 3), Moscone Center
• Session (D106): Late-Breaking Advances in Pulmonary Vascular Disease: Basic Science, Translational, and Clinical Advancements

About AV-001

Originally discovered and designed at Sunnybrook Research Institute at Sunnybrook Hospital in Toronto, AV-001 is being developed by Vasomune Therapeutics, Inc., under a co-development agreement with AnGes, Inc. [TYO: 4563]. AV-001 is a novel investigational medicine that targets the Tie2 receptor, a transmembrane protein most highly expressed on the surface of endothelial cells in the vasculature. AV-001 activates the nonredundant Tie2-Angiopoietin signaling axis, and through stimulation of multiple downstream pathways normalizes the vasculature by enhancing endothelial cell stability, restoring normal barrier defense, and blocking vascular leak. Vascular dysfunction contributes to the underlying disease pathophysiology in patients with bacterial and viral acute respiratory distress syndrome, sepsis, hemorrhagic shock and several other disease syndromes. Importantly, in multiple pre-clinical studies AV-001 tightened endothelial cell-cell junctions and promoted endothelial cell survival, which reduced pulmonary edema, and improved lung function compared to untreated controls translating into significantly improved survival.
