Long-Term Safety Study of Elismetrep for Migraine

This study is looking at the long-term safety of Elismetrep (K-304) for treating acute migraine attacks. You might be able to join if you have already completed a previous study of Elismetrep (Study K-304 P003) and met certain requirements in that study. Researchers want to see how many participants experience side effects (treatment-emergent adverse events or TEAEs), serious side effects (SAEs), or need to stop taking the study drug because of side effects. The study plans to enroll about 1000 people and is currently unclear about its recruitment status. You will receive either Elismetrep or a placebo (an inactive substance).
