A Research Study Examining Migranal and Skin Sensitivity in Subjects With Migraine

This is a three visit trial consisting of a screening visit, one follow-up visit and a termination visit. Subjects will be screened using the Cutaneous Allodynia Screening Tool (Appendix A) and the investigator will determine whether or not the subject experiences episodic migraine headaches associated with cutaneous allodynia. Those subjects who test positive for the afore-stated will then proceed with the treatment phase of the project. Migranal® will be taken by the subject at home at 1-hour following the onset of throbbing pain for one of the two qualifying migraine attacks and at 4-hours following onset of throbbing pain for the second qualifying migraine attack. Migranal® 4 mg. will be self administered by each subject in the following manner: one spray in each nostril, wait 15 minutes then follow with one spray in each nostril. This will deliver the desired 4 mg. dose. Cutaneous allodynia assessments will be made periodically prior to and after administration of study drug. Subjects will be asked to return to the center within 1 week of treating each attack. Subjects will be instructed to treat their 1st qualifying attack within 6 weeks of the screening visit and their 2nd qualifying attack within 6 weeks of their follow-up visit 1. Migraine pain and associated symptoms assessments will be measured by the subjects for 24-hours from the administration of study drug for each attack.
