Brief summary: Randomized, double-blind, placebo-controlled, parallel-group, multicenter study followed by an open-label treatment phase (OLTP). To evaluate the effect of erenumab (AMG 334) compared to placebo on the change from baseline in monthly migraine days.

Detailed description: This is a Phase 2, randomized, double-blind, placebo-controlled study in participants with episodic migraine. The study's double blind treatment phase (DBTP) is designed to evaluate if treatment with erenumab once a month for 6 months compared with placebo is effective in reducing the mean monthly migraine days. Additionally, this study will continue to evaluate the efficacy and safety of erenumab during the OLTP where participants will continue to receive active treatment monthly.

The study also includes a clinical home use (CHU) sub-study to assess a participant's ability to self-administer 140 mg of erenumab. Participants will be randomized 1:1 to use either 2 pre-filled 70 mg/mL autoinjector (AI)/pens or 1 pre-filled 140 mg/mL AI/pen. Participation in the substudy is optional, and no additional samples will be collected for the sub-study.

After implementation of Protocol Amendment 2, the dose of erenumab in the OLTP increased from 70 mg to 140 mg QM. Participants who had already completed week 48 remain on 70 mg QM, participants not yet starting the OLTP, or not yet completing the week 48 visit receive erenumab 140 mg QM for the remainder of the OLTP.

Eligibility criteria: Inclusion Criteria to be assessed prior to entering the subject into the initial screening and/or baseline phase:

* Provided informed consent prior to initiation of any study-specific activities/procedures
* History of migraine (with or without aura) for ≥ 12 months prior to screening according to the International Headache Society (IHS) Classification The International Classification of Headache Disorders (ICHD)-3 (Headache Classification Committee of the IHS, 2013),
* Migraine frequency: ≥ 4 and \< 15 migraine days per month on average across the 3 months prior to screening,
* Headache frequency: \< 15 headache days per month on average across the 3 months prior to screening.

Inclusion Criteria to be assessed during the baseline phase and confirmed prior to randomizing the subject into the double-blind treatment phase:

* Demonstrated at least 80% compliance with the electronic Diary (eDiary),
* 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.

Inclusion Criteria for the Clinical Home Use (CHU) Substudy:

* 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 (nonsteroidal anti-inflammatory drugs \[NSAIDs\], acetaminophen) on ≥ 15 days per month, or Opioid- or butalbital-containing analgesics on ≥ 4 days per month,

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

Hepatitis status will be evaluated by testing for hepatitis B surface antigen (HepBsAg), total hepatitis B core antibody (HepBcAb) and hepatitis C antibody by the central laboratory at initial screening. Polymerase chain reaction (PCR) should be performed to confirm active disease only if total HepBcAb is positive and HepBsAg is negative or if C antibody is positive,

* Subject has any clinically significant vital sign, laboratory, or electrocardiogram (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 (with the exception of prescribed medications such as opioids or barbiturates),
