AV-101 is an investigational, proprietary dry powder inhaled formulation of imatinib which is intended to address the underlying hyperproliferation of cells within the narrowed arteries of the lungs. It is designed to deliver antiproliferative therapy directly to the lungs, allowing more of the drug to access the diseased tissues directly while simultaneously reducing systemic exposure (which was an issue with the previous oral formulation).
