Brief Summary:
The purpose of this study is to assess the safety and effectiveness of topiramate as compared to placebo for the prevention of headaches in patients with chronic migraine. Topiramate has been approved to prevent migraine headaches as well as in the treatment of epilepsy.

Condition or disease Intervention/treatment Phase
Migraine Drug: topiramate Phase 3

Detailed Description:

Migraine headaches can be disabling and can interfere with work and a person's quality of life. Preventing these headaches before they start is the best option. Topiramate, an anti-seizure medication, has been shown to help prevent migraine headaches from occurring. This is a multicenter, randomized, double-blind, placebo-controlled, parallel group study of patients with chronic migraine. The Pretreatment Phase for the study will last up to 56 days and will consist of 2 study periods: a Screening/Washout Period (Day -56 to Day -29) and a Prospective Baseline Period (28 days). Medications being used to prevent migraines will be stopped for 14 to 28 days prior to the Prospective Baseline Period and for the rest of the study. The Prospective Baseline Period will begin on study Day -28 (Visit 2), and patients will maintain a daily headache record during this period. Those who move forward in the study must have had at least 15 headache days during this period, half of which need to be migraine headache days. Patients who finish the Prospective Baseline Period, who have the required rates of headache, and who continue to meet the remainder of the entry criteria will be randomized (like with the toss of a coin) to 1 of 2 treatment groups: topiramate 100 milligrams per day or placebo. The Double-Blind Phase will last 16 weeks. During the first 4 weeks, patients will titrate up to the topiramate dose of 100 milligrams per day or to the maximum tolerated dose, whichever is less. The next 12 weeks is the maintenance phase where you will continue to take the dose that you were taking at the end of the 4-week titration period. The primary hypothesis of this study is that the mean decrease in the number of migraine/migrainous headache days per month is greater in the topiramate group than in the placebo group and topiramate is generally well-tolerated.

Topiramate 25 milligram tablets, 2 tablets by mouth twice daily, or maximum tolerated dose, whichever is less, for 12 weeks, or 2 placebo tablets twice daily for 12 weeks
