  • History of major psychiatric disorders (such as schizophrenia or bipolar disorder) or current evidence of depression. Subjects with anxiety disorder and/or major depressive disorders 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 period.

  • History of seizure disorder or other significant neurological conditions other than migraine. Note: a single childhood febrile seizure is not exclusionary.

  • History of malignancy of any organ system (other than localized basal cell carcinoma of the skin or in situ cervical cancer), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.

  • Human immunodeficiency virus (HIV) infection by history.

  • History or evidence of any other unstable or clinically significant medical condition or clinically significant vital sign, laboratory, or electrocardiogram (ECG) abnormality during that could pose a risk to subject safety or interfere with the study evaluation.

  • Myocardial infarction, stroke, transient ischemic attack, unstable angina, or coronary artery bypass surgery or other re-vascularization procedures within 6 months prior to screening.

  • Score "yes" on item 4 or item 5 of the Suicidal Ideation section of the C-SSRS, if this ideation occurred in the past 6 months, or "yes" on any item of the Suicidal Behavior section, except for the "Non-Suicidal Self-Injurious Behavior" (item also included in the Suicidal Behavior section), if this behavior occurred in the past 2 years.

  • Evidence of drug or alcohol abuse or dependence, based on Investigator discretion within 12 months.

  • Pregnant or nursing (lactating) women.

  • Women of child-bearing potential must use contraception during dosing with study treatment.

  • Use of other investigational drugs within 5 half-lives of enrollment, or until the expected pharmacodynamic effect has returned to baseline, whichever is longer.

  • History of hypersensitivity to any of the study drugs or its excipients or to drugs of similar chemical classes.

  • Previous exposure to AMG334 or exposure to any other prophylactic CGRP-targeted therapy (prior to the study).

AMG334 70 mg/140 mgOral ProphylacticParticipants were randomized to receive 70 mg or 140 mg of AMG334 as a subcutaneous injection once per month for 52 weeks in the Core Phase. Participants were permitted to switch to an approved oral prophylactic based on treatment failure status and at the investigator's and participant's discretion. Participants who completed visits through Week 52 of the Core Phase were eligible to participate in the 52-week Extension Phase of the study.
Oral ProphylacticAMG334Participants were randomized to receive a standard of care (SOC) locally approved oral prophylactic migraine medication once per day for 52 weeks in the Core Phase, as prescribed per local country labels. Participants were permitted to switch to a different approved oral prophylactic based on treatment failure status and at the investigator's and participant's discretion. Participants who completed visits through Week 52 of the Core Phase were eligible to participate in the 52-week Extension Phase of the study.

Primary Outcome Measures
NameTimeMethod
Number of Participants Who Completed Initially Assigned Treatment and Achieved at Least a 50% Reduction From Baseline in Monthly Migraine Days at Month 12Baseline and Month 12

A migraine day was defined as any calendar day in which the participant experienced a qualified migraine headache (onset, continuation, or recurrence of the migraine headache). A qualified migraine headache was defined as a migraine with or without aura, lasting for ≥ 30 minutes, and meeting at least one of the following criteria:

1. ≥2 of the following pain features:

* Unilateral

* Throbbing

* Moderate to severe

* Exacerbated with exercise/physical activity

2. ≥1 of the following associated symptoms:

* Nausea and/or vomiting

* Photophobia and phonophobia

If the participant took a migraine-specific medication (ie, triptan or ergotamine) during aura, or to treat a headache on a calendar day, then it was counted as a migraine day regardless of the duration and pain features/associated symptoms.

In addition to achieving at least a 50% reduction from baseline in monthly migraine days, participants must have also completed their initially assigned treatment through Month 12.

Secondary Outcome Measures
NameTimeMethod
Number of Participants Who Completed Initially Assigned Treatment at Month 12Month 12
Cumulative Mean Change From Baseline on the Monthly Migraine Days to Week 52Baseline and Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 28, Week 32, Week 36, Week 40, Week 44, Week 48, and Week 52

A migraine day was defined as any calendar day in which the participant experienced a qualified migraine headache (onset, continuation, or recurrence of the migraine headache). The mean of monthly migraine days was obtained cumulatively every 4 weeks across 52 weeks (for example, at Week 8 the mean will be based on data from Week 1 to Week 8; and at Week 12 the mean will be based on data from Week 1 to Week 12). The cumulative mean change from baseline in monthly migraine days was derived using difference between cumulative average of each month and baseline monthly migraine days.

Number of Responders as Measured by the Patient's Global Impression of Change (PGIC) Scale at Week 52Baseline and Week 52

The PGIC scale consists of one item which measures the participants' perception of change in their condition relative to the beginning of the study. Responses are rated on a 7-item response scale ranging from very much improved (7) to no change or worsened condition (1). A responder was defined as a participant with a PGIC score of at least 5 (5=moderately better, 6=better, 7=a great deal better), at Week 52 for participants who completed the treatment period at Week 52 on the initially assigned treatment.
