Clinical Trial Summary

This is a research study examining a migraine medicine dihydroergotamine mesylate (DHE-45).It will be used to treat two migraine attacks in subjects who have a history of skin sensitivity associated with their headaches.This skin sensitivity is called cutaneous allodynia (pronounced q-tay-nee-us al-o-din-ee-uh).Cutaneous allodynia is a sensation of pain when a non-noxious stimulus is applied to normal skin. It has been noted in several studies that in subjects with migraine, seventy nine percent of the subjects experienced allodynia on the facial skin on the same side as the headache. It has also been shown that that once allodynia develops, other migraine medicines that would normally be very effective for migraine pain, become much less effective or ineffective. This study will compare the differences,if any, in attacks treated early with this study drug and treated later with the same study drug. It is hoped that that this trial will provide information on the use of DHE-45 in subjects who have cutaneous allodynia. Understanding more about allodynia may help us understand how the pain system works in migraine.

• Subject provides written informed consent prior to any screening procedures being conducted

Exclusion Criteria:

• Pregnant and/or lactating women

• Subjects who, in the investigators opinion, have a history or have evidence of a medical or psychiatric condition that would expose them to an increased risk of a significant adverse event or would interfere with the assessments of efficacy and tolerability during this trial

• Subjects with an abnormal ECG that, in the investigators opinion, would expose them to increased risk of adverse events or interfere with study drug and/or analysis of efficacy/tolerability

• Subjects currently using, or expecting to use during the trial, Cytochrome P450 3A4 (CYP3A4 enzymes) inhibitors (such as protease inhibitors and macrolide antibiotics)

• Subjects with severely impaired hepatic or renal function, as determined by the investigator

• Subjects who have participated in an investigational drug trial in the 30 days prior to the screening visit

• Subjects who currently have or have a history of basilar or hemiplegic migraine

• Subjects who have previously shown hypersensitivity to ergot alkaloids

• Subjects who have a history of non-response to DHE-45, as determined by investigator

• Subjects with uncontrolled hypertension

• Subjects who currently have or who have a history of ischemia and/or vasospastic coronary artery disease

• Subjects who, in the investigators opinion, have significant risk factors of coronary artery disease

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects Reporting Headache Relief at the 2 Hour Post Treatment Assessment. Relief Was Measured as a 2-point Change on a 4-point Scale (0=None, 1=Mild, 2=Moderate, 3=Severe)in Both the Early Treatment and Late Treatment Groups.	Data was collected at 2 hours post treatment to assess pain level. This assessment was done when subjects treated a migraine early (defined as treatment at 2 hours after onset of throbbing pain)and then late (defined as treatment at 4 hours after onset of throbbing pain). The proportion of subjects reporting headache relief at the 2 hour post treatment assessment was determined for each group and then compared.	2 hours post treatment and 4 hours post treatment	No
