Treximet Early Intervention Adolescent Migraine

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.
