1) Adults = 18 to = 65 years of age upon entry into screening
2) History of migraine (with or without aura) for = 12 months prior to screening according to the IHS Classification ICHD-3 based on medical records and/or patient self-report
3) Migraine frequency: = 4 and < 15 migraine days per month on average across the 3 months prior to screening

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

Exclusion Criteria

• Older than 50 years of age at migraine onset
• History of cluster headache or hemiplegic migraine headache
• Unable to differentiate migraine from other headaches
• No therapeutic response with > 2 of the following 7 medication
categories for prophylactic treatment of migraine after an adequate
therapeutic trial. These medication categories are:
- Category 1: Divalproex sodium, sodium valproate
- 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
- Simple analgesics on = 15 days per month, or

• Anticipated to require any excluded medication, device, or procedure
during the study
• Active chronic pain syndromes
• History of major psychiatric 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 (with BDI-II = 19) 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.
• History of seizure disorder or other significant neurological conditions
other than migraine.

skin cancers, cervical or breast ductal carcinoma in situ

transaminase (ALT) or aspartate aminotransferase (AST) = 3.0 x ULN, as
assessed by the central laboratory at initial screening

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
• Evidence of drug or alcohol abuse or dependence within 12 months
prior to screening, based on medical records, patient self-report, or
positive urine drug test performed during screening
