What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Attacks With Sustained Freedom From Headache Pain 2-48 Hours (Modified Intent to Treat Population) | The subject's rating was documented on a four-point scale from no pain (= 0), mild pain (= 1), moderate pain (= 2) to severe pain (= 3). Pain freedom means the pain went from moderate (2) or severe (3) to no pain (0). | At Month 12 of Study Medication Dosing | 
| Percentage of Participants With Attacks With Sustained Freedom From Most Bothersome Symptom 2-48 Hours (Modified Intent to Treat Population) | Subjects were prompted to document the presence of 3 symptoms (photophobia, phonophobia, and nausea) immediately before study drug administration and during the treated migraine attack. | At Month 12 of Study Drug Administration |
