Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: After a run-in phase of 4 weeks, patients will be randomized, according to a 1:1 ratio, to a 24 weeks of treatment, as follow:

* Sequence 1: A/B
* Sequence 2: B/A where: A=monthly subcutaneous erenumab 140 mg for 12 weeks; B=monthly subcutaneous masked placebo for 12 weeks.
Primary purpose: TREATMENT

Brief summary: The purpose of this study is to investigate the effects of erenumab on central sensitization and brain networks connectivity of migraine patients

Detailed description: This is a randomized, double blind, placebo-controlled trial with a 2-sequence, 2-period, 2-treatment crossover design. The study population will consist of adult male and female subjects with a documented history of episodic migraine (4 to 14 baseline migraine days), who have failed at least 2 previous migraine prophylactic treatment for lack of efficacy or tolerability. After a run-in phase of 4 weeks, patients will be randomized, according to a 1:1 ratio, to a 24 weeks of treatment, as follow:

* Sequence 1: A/B
* Sequence 2: B/A where: A=monthly subcutaneous erenumab 140 mg for 12 weeks; B=monthly subcutaneous masked placebo for 12 weeks

Eligibility criteria: Inclusion Criteria:

* Signed informed consent must be obtained prior to participation in the study History of migraine with or without aura for at least 12 months prior to screening 4. Migraine frequency: ≥ 4 and \< 15 migraine days per month on average across the 3 months prior to screening and confirmed during the baseline phase based on diary calculation
* Headache frequency: \<15 headache days per month on average across the 3 months prior to screening and confirmed during the baseline phase based on diary calculation
* Failure to 2 or more previous treatment categories locally indicated for migraine prophylaxis due to either lack of efficacy or poor tolerability

Exclusion Criteria:

* History of cluster headache or hemiplegic migraine headache
* History of chronic pain disorders and neuropathic pain
* History of head trauma or seizure or major psychiatric disorders or suicidal ideation/behavior at any time before screening
* Currently, receiving any other prophylactic treatment for migraine and/or prohibited medications, non-pharmacologic interventions or devices (any substance, non-pharmacologic intervention or device acting at central nervous system), or less than 60 days or 5 half-lives prior to the start of the baseline period, during the baseline period, or treatment period
* Exposure to botulinum toxin in the head and/or neck region within 4 months prior to the start of the baseline period, during the baseline period, or treatment period.
* Taken the following for any indication in any month during the 2 months prior to the start of the baseline period:

  * Ergotamines or triptans on ≥ 10 days per month, or
  * Simple analgesics (non-steroidal anti-inflammatory drugs \[NSAIDs\], acetaminophen) on ≥ 15 days per month, or
  * Opioid- or butalbital-containing analgesics on ≥4 days per month.
* Previous exposure to erenumab or exposure to any other prophylactic CGRP-targeted therapy (prior to and during the study)
* 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 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
* Evidence of drug or alcohol abuse or dependence within 12 months prior to screening, based on medical records or patient self-report
* Pregnant or breastfeeding
* All the clinical conditions for which undergoing an MRI scan is contraindicated

Primary outcomes:
measure: z-score maps change difference between-treatment-groups
timeFrame: baseline, month 3, month 6
measure: z-score maps difference between clinical response groups within the two treatment groups.
timeFrame: baseline, month 3, month 6
Secondary outcomes:
measure: Correlation (by treatment groups and in all patients) between the changes in the resting state functional connectivity strength, measured as z-score maps, and clinical outcomes
timeFrame: month 3, month 6
measure: Between-treatment-groups difference in change of resting state functional connectivity strength, from baseline to month 3 of treatment, measured as z-score maps. in the brain regions involved in migraine symptoms
timeFrame: baseline, month 3, month 6
measure: Correlation (by treatment group and in all patients) between of the changes in the resting state functional connectivity strength of the areas involved in migraine symptoms and the reduction of the respective symptoms
timeFrame: month 3, month 6
measure: Baseline resting state functional connectivity strength will be evaluated by treatment group and in all patients as potential predictors of treatment clinical response defined by the achievement of at least 50% reduction of monthly migraine days
timeFrame: baseline, month 3, month 6
measure: Changes in z-score maps from baseline to month 3 of erenumab treatment and from baseline to month 6 with 3 months with erenumab followed by 3 months of placebo
timeFrame: baseline, month 3, month 6
