NCT05989048

Brief Summary

The purpose of this study is to learn how safe and effective zavegepant is compared to placebo in the acute treatment of migraine in Asian adults. Migraine is a very painful headache with other associated symptoms such as nausea, photophobia and phonophobia. A placebo is a harmless treatment that has no medical effect. This study is seeking for participants who:

  • have at least 1 year of migraine history before entering the study.
  • have 2 to 8 migraine headache attacks of moderate or severe intensity in each of the 3 months before entering the study.
  • have less than 15 days with headaches in each of the 3 months before entering the study. The headaches could be either due to migraine or not. The participants in this study will receive zavegepant or placebo through intranasal route. Intranasal means medicine which is given through nose. Zavegepant or placebo will be taken if the participants have a migraine headache of moderate or severe intensity. The study will compare the experiences of people receiving zavegepant to those of the people receiving placebo. This will help see if zavegepant is safe and effective in Asian adults. Participants will be in this study for up to about 16 weeks. Participants will have 3 study visits at the study clinic and 1 through telephone contact.
