Apo A-1 Milano for Alzheimer's Disease

Tech ID: sha482/059/470/400

 

Introduction

Apolipoprotein A-I (ApoA-I) is the major structural protein component of high-density lipoprotein (HDL). Apolipoprotein A-I Milano (ApoA-IM), a naturally occurring Arg173 to Cys mutant of ApoA-I, was found in a small number of inhabitants of a northern Italian town. Compared to the normal gene (apolipoprotein A-1), the mutant gene (apo A-1 Milano) produces a form of HDL (high-density lipoprotein or "good" cholesterol) that provides greater protection against atherosclerosis and vascular inflammation, as well as Alzheimer’s disease.

 

Technology Description

Dr. Shah and his colleagues have been studying ApoA-I Milano since 1992. With developments over the years, ApoA-I Milano has been shown to reduce atherosclerosis in animal models and in a small phase 2 human trial. Dr. Shah and colleagues have recently found and validated in mouse model that a new serotype of AAV vector is more effective than the vector used before. He also has unpublished data in mouse model showing the therapeutic effects of AAV mediated gene transfer of Apo A-I Milano on atherosclerosis. His pilot work in the Alzhemier’s mouse model showed that Apo A-I Milano gene transfer had positive therapeutic effects measured by several endpoints.

 

Applications

• These findings can be developed into a gene therapy based on AAV delivery platform. It presents promising new treatment options for atherosclerosis and Alzheimer’s disease, where current methods have limitations and are not always effective.

 

Intellectual Property

Patent family includes issued patents and pending applications. Claims are directed towards AAV mediated gene transfer of ApoA-I Milano gene to treat atherosclerosis and Alzheimer’s disease.
