About

Migraine is characterized by attacks of throbbing, moderate or severe headache, associated with nausea, vomiting, and/or sensitivity to light and sound. The main objective of the study is to evaluate how safe and effective the atogepant is in preventing chronic migraine in adult Chinese participants who completed study 3101-303-002. Adverse events will be monitored.

Atogepant is an investigational drug being developed to prevent chronic migraine. All participants will receive the same treatment. Approximately 120 adult participants who completed study 3101-303-002 will be enrolled at approximately 25 centers in China.

All participants will receive atogepant oral tablet once daily for 12 weeks.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
