Brief Summary:
The purpose of this study is to evaluate the safety and effectiveness of individualized doses (50 to 200 milligrams) of topiramate tablets compared against placebo for the prevention of chronic migraine headaches over a period of 16 weeks.

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

Detailed Description:
Previous studies have shown that topiramate is effective in preventing chronic migraine headaches. This study will start with a 4-week baseline period in which no treatment is given, followed by a 12-week period in which each patient's dose is adjusted and then kept stable for the last 4 weeks of the 16-week double-blind phase. The individualized dose will start at 25 milligrams of topiramate per day and will be increased 25 milligrams per day once weekly and then raised to either the target--100 milligrams per day--or the maximum dose that is well tolerated up to 200 milligrams per day. Patients who are randomized to receive topiramate will remain on the optimized dose. The comparison phase of the study is a 16-week period in which the change in migraine days of patients on topiramate (taking at least 50 milligrams per day) is compared with the change in migraine days for patients on the placebo. Also studied will be the patients' health-related quality of life as assessed by questionnaires filled out at specific visits as well as the patients' views of the safety and tolerability of topiramate. The study hypothesis is that the number of migraine days, periods, and attacks from the baseline period to the last 4 weeks in the double-blind period is reduced more in the topiramate group than the placebo group. During the 16-week comparison period, patients will take by mouth a dose of 50 milligrams to 200 milligrams of topiramate daily.

Criteria

Inclusion Criteria:

  • History of migraine for >= 1 year
  • Headache type meets HIS (International Headache Society) criteria for migraine
  • History reflects "chronic" headache--an average of >= 15 migraine days per month in the 3 months preceding trial entry
  • History of chronic migraine for >=1 year>=15 headaches per month with an average duration of 4 hours if not treated
  • Patient is otherwise neurologically and physically healthy on a pre-trial exam.

Exclusion Criteria:

  • Onset of migraine after age 50
  • Use of an anticonvulsant drug in the month prior to trial entry
  • Use of an antidepressant unless dose has been used at a stable dose for >=3 months
  • Use of migraine prevention medicine in the 3 months prior to trial entry unless the drug has been used for at least 3 months and used at a stable dose for at least a month
  • Use of a carbonic anhydrase inhibitor such as acetazolamide (used to treat high blood pressure, glaucoma and seizures) or triamterene (a "water pill" for swelling and high blood pressure).
