Percentage of Participants With Freedom From Pain at 2 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the electronic clinical outcome assessment (eCOA) handheld device. Pain freedom was defined as pain level of none post-dose.
Time frame: 2 hours post-dose
Percentage of Participants With Freedom From Most Bothersome Symptom (MBS) at 2 Hours Post-dose
MBS was reported as nausea, photophobia, or phonophobia at migraine onset using the eCOA handheld device. Symptom status (absent, present) was assessed post-dose using the eCOA handheld device separately for nausea, photophobia, and phonophobia. Freedom from MBS was defined as MBS reported at on-study migraine attack onset that was absent post-dose.
Time frame: 2 hours post-dose
Percentage of Participants With Pain Relief at 2 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Pain relief was defined as pain level of none or mild.
Time frame: 2 hours post-dose
Percentage of Participants Who Were Able to Function Normally at 2 Hours Post-dose
Functional disbaility level was assessed on a 4-point scale (normal function, mildly impaired, severely impaired, requires bedrest) using the eCOA handheld device. Normal function was defined as a functional disability level of normal post-dose in the subset of participants with functional disability (mildly impaired, severely impaired, requires bedrest) at on-study migraine attack onset.
Time frame: 2 hours post-dose
Percentage of Participants With Rescue Medication Use Within 24 Hours Post-dose
Participants who did not experience relief of their migraine headache at the end of 2 hours after dosing with study medication (and after the 2-hour assessments had been completed on the eCOA handheld device) were permitted to use the following rescue medications: aspirin, ibuprofen, acetaminophen up to 1000 mg/day (this includes Excedrin® Migraine), naproxen (or any other type of nonsteroidal anti-inflammatory drug), antiemetics (for example, metoclopramide or promethazine), or baclofen. The participant's use of rescue medication was recorded by the site on a case report form.

Time frame: Through 24 hours post-dose
Percentage of Participants With Freedom From Photophobia at 2 Hours Post-dose
Photophobia (sensitivity to light) status was measured as absent or present in the eCOA handheld device. Freedom from photophobia was defined as photophobia absent post-dose in the subset of participants with photophobia present at on-study migraine attack onset.
Time frame: 2 hours post-dose
Percentage of Participants With Freedom From Phonophobia at 2 Hours Post-dose
Phonophobia (sensitivity to sound) status was measured as absent or present in the eCOA handheld device. Freedom from phonophobia was defined as phonophobia absent post-dose in the subset of participants with phonophobia present at on-study migraine attack onset.
Time frame: 2 hours post-dose
Percentage of Participants With Pain Relief at 60 Minutes Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Pain relief was defined as pain level of none or mild.
Time frame: 60 minutes post-dose
Percentage of Participants Who Were Able to Function Normally at 60 Minutes Post-dose
Functional disbaility level was assessed on a 4-point scale (normal function, mildly impaired, severely impaired, requires bedrest) using the eCOA handheld device. Normal function was defined as a functional disability level of normal post-dose in the subset of participants with functional disability (mildly impaired, severely impaired, requires bedrest) at on-study migraine attack onset.
Time frame: 60 minutes post-dose
Percentage of Participants With Pain Relief at 30 Minutes Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Pain relief was defined as pain level of none or mild.
Time frame: 30 minutes post-dose
Percentage of Participants Who Were Able to Function Normally at 30 Minutes Post-dose
Functional disbaility level was assessed on a 4-point scale (normal function, mildly impaired, severely impaired, requires bedrest) using the eCOA handheld device. Normal function was defined as a functional disability level of normal post-dose in the subset of participants with functional disability (mildly impaired, severely impaired, requires bedrest) at on-study migraine attack onset.
Time frame: 30 minutes post-dose
Percentage of Participants With Sustained Pain Relief From 2 to 24 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Sustained pain relief was defined as pain level of none or mild at 2 hours up to 24 hours post-dose.
Time frame: From 2 hours up to 24 hours post-dose
Percentage of Participants With Sustained Pain Freedom From 2 to 24 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Sustained pain freedom was defined as pain level of none at 2 hours up to 24 hours post-dose.
Time frame: From 2 hours up to 24 hours post-dose
Percentage of Participants With Sustained Pain Relief From 2 to 48 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Sustained pain relief was defined as pain level of none or mild at 2 hours up to 48 hours post-dose.
Time frame: From 2 hours up to 48 hours post-dose
Percentage of Participants With Sustained Pain Freedom From 2 to 48 Hours Post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eCOA handheld device. Sustained pain freedom was defined as pain level of none at 2 hours up to 48 hours post-dose.
Time frame: From 2 hours up to 48 hours post-dose
Percentage of Participants With Freedom From Nausea at 2 Hours Post-dose
Nausea status was measured as absent or present in the eCOA handheld device. Freedom from nausea was defined as nausea absent post-odse in the subset of participants with nausea present at on-study migraine attack onset.
