POD Technology

We have developed our proprietary POD technology to target the vascular rich upper nasal cavity with multiple clinical trials demonstrating rapid absorption and consistent drug biodistribution with ease of use for a patient, provider or caregiver. We believe these characteristics will lead to injection-like clinical outcomes achieved non-invasively. We believe that we are the first company to successfully harness the benefits of delivery to the upper nasal cavity to improve the therapeutic potential of CNS therapies. Traditional nasal pumps have suffered from high variability and low overall absorption. These characteristics have generally limited the nasal route of administration for use with local nasal drugs for allergies or nasal inflammation. We have pioneered research into systemic drug delivery via the upper nasal cavity to the CNS, the anatomy of which are depicted in the picture below. The upper nasal cavity is more permeable, has a higher density of vasculature and has a reduced clearance rate compared to the lower nasal cavity. These advantages of the upper nasal cavity can allow for a better consistency in dosing and uptake as well as the potential for faster time to onset of action.

Our POD™ technology is a patient preferred approach to deliver drugs nasally. Patients or caregivers can administer medications via the POD because it does not require coordination of breathing and activation. The POD technology utilizes propellant to expel the drug substance into the upper nasal cavity to achieve consistent delivery of drug with every dose. Merely place the nasal tip into the nostril and then activate the POD for an easy and consistent administration of medicine. In a clinical trial survey, administration via the POD technology was preferred three to one over traditional nasal pumps.
