Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 6 to 17 years
  • All sexes
  • No healthy volunteers
  • Child

Who may be able to join

  • Children (6 to less than 12 years of age) or adolescent (12 to less than 18 years of age) at the time of signing, if developmentally appropriate, the formal assent to participate to the study.
  • Participant's parent or legal representative has provided written informed consent before initiation of any study-specific activities/procedures.
  • History of migraine (with or without aura) for greater than or equal to 12 months before screening according to the IHS Classification ICHD-3 (Headache Classification Committee of the International Headache Society, 2013) based on medical records and/or participant self-report or parents' or legal representative's report.
  • The following ICHD-3 specifications for pediatric migraine (participants aged less than 18 years), should be considered for the diagnosis of migraine:
  • Attacks may last 2 to 72 hours.
  • Migraine headache is more often bilateral than in adults; unilateral pain usually emerges in late adolescence or early adult life.
Show all 14Show fewer
  • Migraine headache is usually frontotemporal. Occipital headache in children is rare and calls for diagnostic caution.
  • A subset of otherwise typical participants have facial location of pain, which is called 'facial migraine' in the literature; there is no evidence that these participants form a separate subgroup of migraine participants.
  • In young children, photophobia and phonophobia may be inferred from their behavior.
  • History of less than 15 headache days per month of which greater than or equal to 4 headache days were assessed by the participant as migraine days in each of the 3 months prior to screening (refer to Section 5.6 for definition of migraine day).
  • Criteria to be assessed prospectively during the 4-week baseline phase and confirmed before randomizing the participant into the DBTP:
  • Migraine frequency: greater than or equal 4 and less than 15 migraine days based on the eDiary data during the last 28 days of the baseline phase if greater than 28 days in duration
  • Headache frequency: less than 15 headache days based on the eDiary data during the last 28 days of the baseline phase if greater than 28 days in duration.
  • Demonstrated at least 80% compliance with the eDiary based on the last 28 days of the baseline period, if greater than 28 days in duration (eg, completing eDiary items for at least 23 out of the last 28 days of the baseline phase).

Who cannot join

  • History of cluster headache or hemiplegic migraine headache.
  • No therapeutic response with greater than 2 of the following 10 medication categories for prophylactic treatment of migraine after an adequate therapeutic trial. These medication categories are:
  • Category 1: beta blockers (eg, propranolol, atenolol, bisoprolol, metoprolol, nadolol, nebivolol, pindolol, timolol)
  • Category 2: tricyclic antidepressants (eg, amitriptyline, nortriptyline, protriptyline)
  • Category 3: topiramate
  • Category 4: divalproex sodium, sodium valproate
Show all 38Show fewer
  • Category 5: serotonin-norepinephrine reuptake inhibitors (eg, venlafaxine, desvenlafaxine, duloxetine, milnacipran)

  • Category 7: flunarizine, cinnarizine
  • Category 8: botulinum toxin
  • Category 9: lisinopril/candesartan

  • Lack of sustained response to a medication.
  • Partial, suboptimal response to a medication.
  • Failure to tolerate a therapeutic dose.

Participants with anxiety disorder and/or mild major depressive disorder (with PHQ-A score ≤ 9) 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. Participant must have been on a stable dose within the 3 months before the start of the baseline phase.
  • Use of prohibited medication within 1 month before the start of the baseline phase and/or during the baseline phase.
  • Use of prohibited devices (such as stimulation devices) or procedures (such as acupuncture, biofeedback, relaxation techniques, or psychotherapy) with the goal of preventing migraines, within 3 months before the start of the baseline phase and/or during the baseline phase.
  • Participants receiving Cognitive Behavioral Therapy (CBT) are excluded unless they are on a stable, maintenance phase of a CBT program for migraine for at least 3 months before the start of the baseline phase. Participants undergoing CBT are considered on a stable, maintenance phase if they have undergone greater than or equal 6 weekly or biweekly sessions of CBT administered by adequately trained psychologists and who, for at least 3 months before the start of the baseline phase, only follow "booster" CBT sessions at a monthly, bimonthly or quarterly frequency. Note: Participants who have discontinued CBT within 3 months prior to the start of the baseline phase are eligible for the study provided that there is evidence of CBT failure/lack of efficacy prior to initial screening (per medical records or investigator's assessment).

About this study

Official title: A Phase 3, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Erenumab in Children (6 to < 12 Years) and Adolescents (12 to < 18 Years) With Episodic Migraine (OASIS PEDIATRIC [EM])

This study will evaluate the efficacy and safety of erenumab in migraine prevention in children (6 to <12 years) and adolescents (12 to <18 years) with episodic migraine. The study hypothesis is that in pediatric participants with episodic migraine, the combined erenumab dose group has a greater reduction from baseline to week 9 through week 12 (month 3) in monthly migraine days (MMDs) when compared with placebo in the double-blind treatment phase (DBTP).

Read the detailed description

This study is a Phase 3, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of erenumab in migraine prevention in children (6 to <12 years) and adolescents (12 to <18 years) with episodic migraine.

The trial consists of four phases: screening (up to 3 weeks of initial screening and a 4-week prospective baseline phase); the DBTP (24 weeks for Group 1 participants; 12-weeks for Group 2 participants) in which participants receive placebo or Erenumab dose 1, dose 2 or dose 3 (based on participant's body weight) via subcutaneous injection once a month; the optional dose level blinded extension phase (40 weeks), in which all participants are assigned to receive dose 1, dose 2 or dose 3 of Erenumab; and a 12 weeks safety follow-up phase (16 weeks after the last dose of investigational drug).

The study intends to enroll 436 participants (376 adolescents and up to 60 children).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Erenumab Dose 1, Erenumab Dose 2 and Erenumab Dose 3 in people with Migraine, run by Amgen at 11 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 38 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 14 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Poland, Colombia, United States, Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in MMDs (time frame: Baseline through week 12 of the double blind treatment phase). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Oct 2026.
