Study of Telcagepant (MK-0974) in Participants With Moderate to Severe Acute Migraine With or Without Aura (MK-0974-011)

The purpose of this study is to investigate the efficacy and safety of telcagepant (MK-0974) compared to an approved medication for acute migraine. This study was conducted as a "triple-dummy" design; for each dose of study drug, participants each received 3 forms of study drug (2 capsules of active and/or placebo and 1 tablet of active and/or placebo) and were instructed to take one of each form of study drug at dosing time. The primary hypotheses of this study are that telcagepant is superior to placebo in Pain Freedom at 2 Hours Post-Dose, Pain Relief at 2 Hours Post-Dose, Absence of Photophobia at 2 Hours Post-Dose, Absence of Phonophobia at 2 Hours Post-Dose and Absence of Nausea at 2 Hours Post-Dose.
