Criteria to be assessed during the baseline phase and confirmed prior to randomizing the subject into the double-blind treatment phase:
• Migraine frequency: = 4 and < 15 migraine days during the baseline phase based on the eDiary calculations
• Headache frequency: < 15 headache days during the baseline phase based on the eDiary calculations
• Demonstrated at least 80% compliance with the eDiary

- Category 2: Topiramate
- Category 3: Beta blockers
- Category 4: Tricyclic antidepressants
- Category 5: Serotonin-norepinephrine reuptake inhibitors
- Category 6: Flunarizine, verapamil
- Category 7: Lisinopril, candesartan
• Used a prohibited medication, device, or procedure within 2 months prior to the start of the baseline phase or during the baseline phase
• Received botulinum toxin in the head and/or neck region within 4 months prior to the start of the baseline phase or during the baseline phase
• Taken the following for any indication in any month during the 2 months prior to the start of the baseline phase:
- Ergotamines or triptans on = 10 days per month, or

• Active chronic pain syndromes (such as fibromyalgia and chronic pelvic pain)
• History of major psychiatric disorder (such as schizophrenia and bipolar disorder), or current evidence of depression based on a Beck Depression Inventory (BDI)-II total score > 19 at screening. Subjects with anxiety disorder and/or major depressive disorder are permitted in the study if they are considered by the investigator to be stable and are taking no more than 1 medication for each disorder. Subjects must have been on a stable dose within the 3 months prior to the start of the baseline phase.

• Myocardial infarction (MI), stroke, transient ischemic attack (TIA), unstable angina, or coronary artery bypass surgery or other revascularization procedure within 12 months prior to screening
• History or evidence of any other unstable or clinically significant medical condition, that in the opinion of the investigator, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion
• Subject has any clinically significant vital sign, laboratory, or ECG abnormality during screening that, in the opinion of the investigator, could pose a risk to subject safety or interfere with the study evaluation
• The subject is at risk of self-harm or harm to others as evidenced by past suicidal behavior or endorsing items 4 or 5 on the Columbia-Suicide Severity Rating Scale (C-SSRS) assessed at screening
