简要总结
Rimegepant has obtained approval in the United States (US), United Kingdom (UK), European Union (EU), and other countries for the acute treatment of migraine with and without aura in adults, and, in some countries, the preventive treatment of episodic migraine in adults. Currently, rimegepant is being studied for the acute treatment of migraine in children and adolescents, as well as for the prevention of migraine in children and adolescents with episodic migraine.
The purpose of this study is to compare the efficacy and safety of rimegepant to placebo as a preventative treatment for migraine in adolescents of 12 to 18 years of age with chronic migraine.
