The Effectiveness of Almotriptan Malate (AXERT®) 12.5 Milligrams When Taken at the Onset of Migraine Pain

Ortho-McNeil Neurologics, Inc.1,450 enrolled

Overview

The purpose of this study is to evaluate the effectiveness and safety of AXERT when treating a migraine at the onset of headache pain, as compared to treating a migraine only after the headache pain has reached at least moderate intensity..

AXERT has been approved by the FDA for the treatment of migraine headache with or without aura in adults. Early treatment of a migraine headache, independent of headache pain intensity symptoms, may provide the optimal therapeutic response. This is a multi-center, open label study to test the efficacy (effectiveness) and tolerability of AXERT when treating a migraine at the onset of headache pain versus treating a migraine only after the headache pain has reached at least moderate intensity. Patients will self-administer 12.5 milligrams of AXERT for the treatment of 2 migraine headaches. Centers will be randomly assigned to 1 of 2 treatment interventions in which patients will sequentially treat both migraine headaches with 12.5 milligrams of AXERT using either the early treatment regimen (ET; ie, at the onset of pain) or conditional treatment regimen (CT; ie, after the headache has reached at least moderate intensity). Data will be collected regarding treatment response during and after each migraine headache. For each headache, patients will record study information and data during 3 telephone calls using Interactive Voice Response System (IVRS) technology. It is expected that patients who take 12.5 milligrams of AXERT at the first sign of pain of any intensity due to a migraine headache will experience an overall shorter duration of their migraine than patients who take AXERT 12.5 mg when their migraine pain has reached at least moderate pain intensity. In addition, it is expected that almotriptan malate (AXERT®) is generally well-tolerated. AXERT 12.5 milligram tablet orally either at the onset of migraine pain (within 1 hour of the start of a migraine-ET regimen) or when migraine pain reaches at least moderate intensity (CT regimen).
