Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPercentage of Participants With Freedom From Pain at 2 Hours Post-dose2 hours post-dosePain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the electronic diary (eDiary). Pain freedom was defined as pain level of none.
PrimaryPercentage of Participants With Freedom From Most Bothersome Symptom (MBS) at 2 Hours Post-dose2 hours post-dose
MBS was reported as nausea, photophobia, or phonophobia at migraine onset using the eDiary. Symptom status (absent, present) was assessed post-dose using the eDiary separately for nausea, photophobia, and phonophobia. Freedom from MBS was defined as MBS reported at onset that was absent post-dose.
SecondaryPercentage of Participants With Pain Relief at 2 Hours Post-dose2 hours post-dosePain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Pain relief was defined as pain level of none or mild.
SecondaryPercentage of Participants With Freedom From Functional Disability at 2 Hours Post-dose2 hours post-dose
Functional disability level was assessed in the eDiary on a 4-point scale: normal function, mild impairment, severe impairment, required bed rest. Freedom from functional disability was defined as normal function.
SecondaryPercentage of Participants With Sustained Pain Relief From 2 to 24 Hours Post-doseFrom 2 hours up to 24 hours post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Sustained pain relief was defined as pain level of none or mild at 2 hours up to 24 hours post-dose with no rescue medication use through 24 hours post-dose.
SecondaryPercentage of Participants With Sustained Freedom From Most Bothersome Symptom (MBS) From 2 to 24 Hours Post-doseFrom 2 hours up to 24 hours post-dose
MBS was reported as nausea, photophobia, or phonophobia at migraine onset using the eDiary. Symptom status (absent, present) was assessed post-dose using the eDiary separately for nausea, photophobia, and phonophobia. Sustained freedom was defined as MBS reported at onset that was absent at 2 hours up to 24 hours post-dose with no rescue medication use through 24 hours post-dose.
SecondaryPercentage of Participants With Rescue Medication Use Within 24 Hours Post-dose24 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 eDiary) 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 (e.g., metoclopramide or promethazine), or baclofen. The participant's use of rescue medication was recorded by the participant in a paper diary.
SecondaryPercentage of Participants With Sustained Freedom From Functional Disability From 2 to 24 Hours Post-doseFrom 2 hours up to 24 hours post-dose
Functional disability level was assessed in the eDiary on a 4-point scale: normal function, mild impairment, severe impairment, required bed rest. Sustained freedom from functional disability was defined as normal function at 2 hours up to 24 hours post-dose with no rescue medication use through 24 hours post-dose.
SecondaryPercentage of Participants With Sustained Pain Relief From 2 to 48 Hours Post-doseFrom 2 hours up to 48 hours post-dose
Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the eDiary. Sustained pain relief was defined as pain level of none or mild at 2 hours up to 48 hours post-dose with no rescue medication use through 48 hours post-dose.
SecondaryPercentage of Participants With Sustained Freedom From Most Bothersome Symptom (MBS) From 2 to 48 Hours Post-doseFrom 2 hours up to 48 hours post-dose
MBS was reported as nausea, photophobia, or phonophobia at migraine onset using the eDiary. Symptom status (absent, present) was assessed post-dose using the eDiary separately for nausea, photophobia, and phonophobia. Sustained freedom was defined as MBS reported at onset that was absent at 2 hours up to 48 hours post-dose with no rescue medication use through 48 hours post-dose.
