The study involves approximately 105 adolescent (ages 12-17) subjects to be screened at 4 sites across the US. All subjects enrolled will treat up to 4 MILD migraines over a 6 month period. They will be required to have three office visits during the six months. All subjects will be randomized to either Treximet (85mg Imitrex/500mg Naproxen Sodium) or Placebo (sugar-pill) in four of the five treatment arms with a 3 to 1 ratio. A fifth treatment arm will treat all 4 migraines with active drug, Treximet. The hypothesis is that Treximet will prove to be a safe and effective treatment for this population, that has so few treatment for migraine. And Treximet will be superior over placebo for pain free endpoints at 2 and 24 hours.

There are two primary treatment comparisons for this study: 1) the percentage of subjects' pain free at 2 hours after treatment with TREXIMET versus placebo across attacks, and 2) the percentage of subjects who are sustained pain free at 24 hours after treatment with TREXIMET versus placebo across attacks.

The following alternative hypothesis will be tested to see if there is a difference in the proportion of subjects who are pain free at 2 hours with TREXIMET versus placebo at all attacks, OR there is a difference in the proportion of subjects who are sustained pain free at 24 hours with TREXIMET versus placebo at all attacks.

Inclusion Criteria:

1. Male or female subjects between the ages of 12-17.

3. Subject is able to distinguish migraine from other headaches and can determine when a mild headache will become a moderate/severe migraine.

Exclusion Criteria

Subjects meeting any of the following criteria must not be enrolled in the study:

1. Subject is < 74 pounds (33.3kg) and no greater than 260lbs (117.9kg)
2. Subject has greater than or equal to 15 headache days per month in total.
3. Subject has secondary headaches i.e. complex migraine, hemiplegic, or basilar.
4. Subject, in investigators opinion is likely to have unrecognized cardiovascular or cerebrovascular disease.

6. Subject has a history of congenital heart disease, cardiac arrhythmias requiring medication, or a history of a clinically significant electrocardiogram abnormality that, in the investigator's opinion, contraindicates participation in the study.
7. Subject has evidence or history of any ischemic vascular diseases including: ischemic heart disease, ischemic abdominal syndromes, peripheral vascular disease, or signs/symptoms consistent with the above.
8. Subject has a evidence or history of central nervous system pathology including stroke and/or transient ischemic attacks (TIAs), epilepsy or structural brain lesions which lower the convulsive threshold, or has been treated with an anti-epileptic drug for seizure control within 5 years prior to screening.
9. Subject has a history of impaired hepatic or renal function that, in the investigator's opinion, contraindicates participation in this study.
10. Subject has a hypersensitivity, allergy, intolerance, or contraindication to the use any triptan, NSAID, or aspirin (including all sumatriptan and naproxen preparations) or has nasal polyps or asthma.
11. Subject has used an ergot medication in the previous three months for migraine prophylaxis or is taking a medication that is not stabilized for at least two months for either chronic or intermittent migraine prophylaxis or other co-morbid condition.
12. Subject has taken or plans to take a monoamine oxidase inhibitor (MAOI) including herbal preparations containing St. Johns Wort (Hypericum perforatum), anytime within the two weeks prior to screening and two weeks past exit of study.
13. Subject has a history of any bleeding disorder or is currently taking any anti-coagulant or any antiplatelet agent.

17. Subject has participated in any investigational drug trial within the previous 4 weeks or plans to participate in another study at any time during this study.

There is no plan in place to enter every single patient in separtely

104 subjects were randomized in the study but only 94 subjects actually dosed with study drug and completed at least one diary assessment post dose.

Entire Study 3 years

All adverse events are reported here whether patient had taken active drug or placebo and it is not separated per intervention
