This Medfyle was published more than two years ago. More recent Medfyle on this topic may now be available.
- TOP 301 was an open-label study of safety, tolerability, patient acceptability, and exploratory efficacy of long-term intermittent usage of nasal dihydroergotamine (DHE) mesylate self-administered over 24 and 52 weeks.
- The combination product of Precision Olfactory Delivery (POD) and DHE mesylate was easy to use and preferred over current therapy
- Exploratory efficacy data suggests that delivery to the upper nasal space resulted in pain freedom in 33.1% of patients, most bothersome symptom freedom in 49.1% of patients, and pain relief in 66.3% of patients at 2 hours that was sustained through 24 hours in the majority of patients.
