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 3. Patients 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 study entry. 4. Patients with contraindications for use of triptans may be included provided they meet all other study entry criteria. Key Exclusion Criteria: 1. Patient history of HIV disease 2. Patient history with current evidence of uncontrolled, unstable or recently diagnosed cardiovascular disease, such as ischemic heart disease, coronary artery vasospasm, and cerebral ischemia.

Outcomes

Primary Outcomes

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 diary (eDiary). Pain freedom was defined as pain level of none.

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 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.

Time frame: 2 Hours

Secondary Outcomes

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 eDiary. Freedom from photophobia was defined as photophobia absent.

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 eDiary. Freedom from phonophobia was defined as phonophobia absent.

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 eDiary. Pain relief was defined as pain level of none or mild.

Time frame: 2 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 eDiary. Freedom from nausea was defined as nausea absent.

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 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.

Time frame: 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 eDiary. Sustained pain freedom was defined as pain level of none at 2 hours up to 24 hours post-dose with no rescue medication use through 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 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.

Time frame: From 2 hours up to 24 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 eDiary. Sustained pain freedom was defined as pain level of none 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

Percentage of Participants With Sustained Pain Relief From 2 to 48 Hours Post-dose
