A Dose-Finding Study of Topiramate (JNS019) in Participants With Migraine

Summary

The purpose of this study is to determine a recommended dose of topiramate in participants with migraine (type of severe headache that occurs periodically and is often associated with nausea, vomiting, and constipation or diarrhea), to verify the superiority (statistically more effective) of the drug to placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial), and to assess if a same therapeutic effect can be observed between this study and overseas Caucasian clinical studies.
