POD Technology

Impel NeuroPharma’s POD™ nasal drug delivery platform is designed to deliver drugs to the upper nasal cavity for improved biodistribution. By delivering therapeutics to the upper nasal cavity, the POD™ nasal delivery platform takes advantage of the vascular rich olfactory region for improved bioavailability and has the potential to directly target the brain via the olfactory and trigeminal nerves. Delivery of therapeutically meaningful levels of drugs may allow for the development of more effective formulations of existing drugs, as well as the development of novel drugs that otherwise would not cross the blood-brain barrier, thereby expanding the range of treatment options available to patients.

The nasal cavity is a vastly underutilized entry point for therapeutics into systemic circulation. The primary challenge in achieving significant nasal drug delivery is depositing drugs in the deeper regions of the nasal cavity where systemic absorption may be more consistent. Due to the complex architecture of this area, drugs delivered with standard nasal devices such as droppers, sprays, or pumps typically deposit less than 5% of the compound into the olfactory region and thus, do not contribute meaningfully to systemic levels. In addition, these low levels do not provide a significant opportunity to treat CNS disorders. Impel’s POD™ technology results in a large fraction of drug deposition in this region, which can lead to direct uptake along the olfactory pathways, as well as greater and faster uptake into the systemic vasculature (depending on the drug).
