December 20, 2006 – OptiNose is pleased to announce the results of a Phase I study in 12 patients evaluating the effects of intranasal sumatriptan in subjects suffering from migraine. The study compared the effects of intranasal sumatriptan nasal spray delivered by the OptiNose device with a sub-cutaneous reference dose on glyceryltrinitrate-induced migraine in migraineurs, using EEG biomarkers.
The results demonstrate that sumatriptan at doses of 10 mg or 20 mg delivered intranasally by the OptiNose powder nasal drug delivery device is rapidly absorbed with similar effects on the EEG profile to a dose of 6mg administered subcutaneously.

About Bi-directional Nasal Delivery Technology
OptiNose’s bidirectional nasal delivery technology significantly improves delivery to the targeted sites deep into the nose. While exhaling into the device, the soft palate automatically closes off the nasal cavity completely. The breath enters one nostril through a sealing nozzle and triggers the release of drug particles into the airflow. This action causes the narrow nasal passages to expand and carry these particles beyond the nasal valve to targeted sites. After delivering drug particles to the targeted sites, the air flow then exits the nasal cavity through the other nasal passage in the opposite direction.
