It is often accompanied by feeling or being sick and a sensitivity to bright lights and sound. Migraines are caused by a series of events when the brain gets stimulated or activated, which causes the release of chemicals that cause pain. Corabotase (also known as IPN10200) is a medication that stops the release of these chemical messengers. Participants with episodic migraine (EM) or chronic migraine (CM) will be included in both Step 1 and Step 2\. "Headache days" are when participants experience headaches that meet the criteria for a migraine or a headache without the additional migraine-specific symptoms. "Migraine days" occur when the headache displays clear migraine characteristics. This study aims to determine: \* The safety and efficacy of injecting Corabotase directly into the muscles of the head and neck to prevent EM and CM, \* The right amount (dose) of Corabotase to inject at each point, \* The total amount (dose) of Corabotase that provides the best balance between safety and efficacy preventing migraines. Participants will need to complete a daily electronic migraine Diary (eDiary) and questionnaires throughout the study. The total study duration for a participant will be up to 44 weeks.
