Inclusion criteria
Key Inclusion Criteria: 1\. Subject has at least 1 year history of migraines (with or without aura), consistent with a diagnosis according to the International Classification of Headache Disorder, 3rd Edition, Beta version \[1\] including the following: 1. Migraine attacks present for more than 1 year with the age of onset prior to 50 years of age 2. Migraine attacks, on average, lasting about 4-72 hours if untreated 3. Not more than 8 attacks of moderate to severe intensity per month within the last 3 months 4. Consistent migraine headaches of at least 2 migraine headache attacks of moderate or severe intensity in each of the 3 months prior to the Screening Visit and maintains this requirement during the Screening period 5. Less than 15 days with headache (migraine or non-migraine) per month in each of the 3 months prior to the Screening Visit and maintains this requirement during the Screening Period. 6. Subjects on prophylactic migraine medication are permitted to remain on therapy provided they have been on a stable dose for at least 3 months prior to screening visit and the dose is not expected to change during the course of the study. 7. Subjects with contraindications for use of triptans may be included provided they meet all other study entry criteria. Key
Exclusion criteria
1. Subject with a history of HIV disease 2. Subject history with current evidence of uncontrolled, unstable or recently diagnosed cardiovascular disease, such as ischemic heart disease, coronary artery vasospasm, and cerebral ischemia. subjects with Myocardial Infarction (MI), Acute Coronary Syndrome (ACS), Percutaneous Coronary Intervention (PCI), cardiac surgery, stroke or transient ischemic attack (TIA) during the 6 months prior to screening 3.

Percentage of Participants With Sustained Freedom From Most Bothersome Symptom (MBS) From 2 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.
Time frame: From 2 hours up to 48 hours post-dose
Population: The analysis was performed on mITT participants.
