This study is testing an investigational inhaled migraine medication to see how well it works, how safe it is, and how well people tolerate it. Adults with migraine will receive both the study medication (ASY202) and a placebo (inactive treatment) at different times during the study. Neither participants nor study staff will know which treatment is given at the time. The medication is taken using a handheld dry powder inhaler to treat migraine attacks when they occur.
Following screening, eligible participants will be enrolled and randomized to one of two treatments sequences i.e. one treatment sequence will receive ASY202 in treatment period 1 followed by placebo in treatment period 2 and other treatment sequence will receive placebo in treatment period 1 followed by ASY202 in treatment period 2.
The study lasts about 16 weeks and includes a screening period, two treatment periods (with a minimum of 7 days washout period between the treatment periods), and a safety follow-up visit.
