Group	Intervention	Description
Placebo	Placebo	Placebo to match
Sumatriptan and Naproxen 1	Sumatriptan and Naproxen Sodium	Sumatriptan succinate and naproxen sodium combination 10mg/60mg
Sumatriptan and Naproxen 3	Sumatriptan and Naproxen Sodium	Sumatriptan succinate and naproxen sodium combination 85mg/500mg

Primary Outcome Measures

Name	Time	Method
Number of Participants Who Were Pain Free at 2 Hours Post-dose	2 hours after single dose of double-blind treatment (Randomization through Week 13)	Participants were evaluated (self-assessment) for pain intensity by using a 4-point rating scale: 0=none, 1=mild, 2=moderate, and 3=severe. Participants with pain-free response were considered as those who had a reduction in migraine headache pain from moderate (score=2) or severe (score=3) at baseline to none (score=0) post-treatment, without the use of rescue medication (additional medication taken by participants for the treatment of migraine pain or associated symptoms) prior to or at 2 hours post-dose.

Secondary Outcome Measures

Name	Time	Method
Number of Participants Sustained Pain-free From 2-24 Hours	2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)	Participants with sustained pain-freedom were defined as those with pain-freedom at 2 hours post-dose that was maintained up to 24 hours post-treatment without the use of rescue medication.
Number of Participants Photophobia-free at 2 Hours Post-dose	2 hours after single dose of double-blind treatment (Randomization through Week 13)	The number of participants who did not have photophobia (sensitivity to light) at 2 hours post dose was analyzed.
Number of Participants Phonophobia-free at 2 Hours Post-dose	2 hours after single dose of double-blind treatment (Randomization through Week 13)	The number of participants who did not have phonophobia (sensitivity to sound) at 2 hours post dose was analzyed.
Number of Participants Pain-free at 1 Hour Post-dose	1 hour after single dose of double-blind treatment (Randomization through Week 13)	Participants with a pain-free response at 1 hour post-dose were considered as those who had a reduction in migraine headache pain from moderate (a score of 2) or severe (a score of 3) at baseline to none (a score of 0) post-treatment, without the use of rescue medication prior to or at 1 hour post dose.
Number of Participants Sustained Photophobia-free From 2-24 Hours	2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)	Participants with sustained freedom from photophobia were those with an absence of photophobia (sensitivity to light) from 2 to 24 hours post-dose without the use of rescue medication.
Number of Participants Sustained Phonophobia-free From 2-24 Hours	2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)	Participants with sustained freedom from phonophobia were those with an absence of phonophobia (sensitivity to sound) from 2 to 24 hours post-dose without the use of rescue medication.
Number of Participants Sustained Nausea-free From 2-24 Hours	2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)	Participants with sustained freedom from nausea were those with an absence of nausea from 2 to 24 hours post-dose without the use of rescue medication.
Number of Participants Who Used Rescue Medication From 2 to 24 Hours Post Dose	2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)	Rescue medication was defined as an additional medication taken by participants for the treatment of migraine pain or associated symptoms within 24 hours of dosing with investigational product. Permitted rescue medications included oral naproxen sodium (maximum 15 mg/kg), oral over-the-counter pain reliever, and anti-emetics. This outcome measure included only participants who rescued from 2 to 24 hours post-dose, inclusive.
Number of Participants Who Used Their First Dose of Rescue Medication Through the Indicated Time Points	Dosing to 24 hours after single dose of double-blind treatment (Randomization through Week 13)	Rescue medication was defined as an additional medication taken by participants for the treatment of migraine pain or associated symptoms within 24 hours of dosing with double-blind treatment. In addition to participants who rescued from 2 to 24 hours post-dose, inclusive, this outcome measure also included nine protocol violators who rescued \< 2 hours post-treatment.
Number of Participants Nausea-free at 2 Hours Post-dose	2 hours after single dose of double-blind treatment (Randomization through Week 13)	The number of participants who did not have nausea at 2 hours post dose was analzyed.
