AV-353

AV-353 is the Company’s potent, selective, high affinity inhibitory antibody specific to Notch 3. The Notch 3 signaling pathway is important in cell-to-cell communication involving gene regulation mechanisms that control multiple cell differentiation processes during the entire life cycle. Scientific literature has implicated the Notch 3 receptor pathway in multiple diseases, including cancer, cardiovascular diseases and neurodegenerative conditions. Publications, including Nature Medicine (2009), have implicated the Notch 3 pathway in Pulmonary Arterial Hypertension (PAH). PAH is a rare and life-threatening disorder that affects approximately 250,000 people worldwide and is caused by enlargement of the arterial walls in small arteries between the heart and the lungs, resulting in restricted blood flow.

Current treatments in PAH focus only on controlling symptoms by avoiding vasoconstriction and increasing vasodilation of vessels and do not reverse the underlying cause of the disease. In contrast, with the results of a recently concluded preclinical animal studies supported by AVEO, AV-353 has generated a growing body of preclinical data that supports AV-353’s ability to potentially reverse the disease phenotype, which would represent a potential disease-modifying approach to treatment. AVEO is currently seeking a partner to develop and commercialize AV-353 worldwide in PAH.
