Potential Impact (Benefit) of Preventative Treatment With Topamax on the Effectiveness of Axert in the Acute Treatment of Migraine

May 16, 2011 updated by: Janssen-Ortho LLC

Efficacy of AXERT (Almotriptan Malate) in the Acute Treatment of Migraine: A Pilot Study of the Potential Impact of Preventive Therapy With TOPAMAX (Topiramate)

The purpose of this study is to evaluate the impact of topiramate (migraine prevention medicine) on the effectiveness of almotriptan malate (acute migraine medicine) when treating acute migraine headaches.

Detailed Description

Migraine afflicts greater than 28 million adults in the United States. Acute treatments, such as almotriptan malate, target the symptoms of a migraine attack. Preventive treatments, such as topiramate, primarily target the generation of attacks and may decrease use of acute treatments. Preventive treatments, by a process of neurostabilization, may result in an additive effect on almotriptan malate to improve acute treatment intervention response during a migraine attack. This is a randomized, double blind, parallel group multicenter study that will enroll patients 18-65 years old with a history of 3-12 migraine headaches each month for the past 3 months. The total study duration will be approximately 32 weeks. The study is divided into 4 phases as follows: A Screening Phase that lasts one month; An Open Label Phase where all patients will be treated with topiramate gradually dosed to 100mg a day lasting 6 weeks; A Double Blind Phase lasting 19 weeks at which time patients will be randomized to stay on topiramate 100mg per day or switch to placebo topiramate (50:50 chance) and a Taper/Exit Phase lasting 2 weeks. Almotriptan malate will be used for all migraine headaches during the study as needed. The study hypothesis is that the combination of almotriptan malate and topiramate will have a better clinical response than the combination of almotriptan malate and placebo topiramate. Migraine pain information will be collected from each patient with the use of a Personal Digital Assistant (PDA or Palm Pilot) throughout the study for each migraine attack. Commercial Topiramate will be gradually increased to 100mg/day in approximately 4-6 weeks. You will then be randomized to either Topiramate or Placebo, dosed at 100mg a day, for the remainder of the study (18 weeks). AXERT 12.5mg may be taken to treat migraine headaches during the study.
