Brief Summary:
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 chronic migraine. The study hypothesis is that in pediatric subjects with chronic 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).

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 chronic migraine.

The trial consists of four phases: screening (up to 3 weeks of initial screening and a 4-week prospective baseline phase); the double-blind treatment phase (24 weeks) 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 286 participants (256 adolescents and 30 children).

Primary Outcome Measures :
  1. Change from baseline in monthly migraine days (MMDs) [ Time Frame: Baseline through week 12 of the double blind treatment phase ]
    To evaluate the effect of erenumab compared with placebo on the change in MMDs from baseline to week 9 through week 12 (month 3) of the double-blind treatment period (DBTP).


Secondary Outcome Measures :
  1. Change in monthly headache days from baseline [ Time Frame: Baseline through week 12 of the double blind treatment phase ]
    To evaluate the effect of erenumab compared with placebo on the change from baseline in monthly headache days to week 9 through week 12 (month 3) of the double-blind treatment period (DBTP)

  2. Proportion of subjects with at least 50% reduction in monthly migraine days (MMDs) from baseline [ Time Frame: Baseline through week 12 of the double blind treatment phase ]
    To evaluate the effect of erenumab compared with placebo on the proportion of subjects with at least 50% reduction in MMDs from baseline to week 9 through week 12 (month 3) of the double-blind treatment period (DBTP)

  3. Change in monthly migraine days (MMDs) from baseline to the average of the first 3 months [ Time Frame: Baseline through week 12 of the double blind treatment phase ]
    To evaluate the effect of erenumab compared with placebo on the change in MMDs from baseline to the average of the first 3 months (week 1 through week 12) of the double-blind treatment period (DBTP).

  4. Change in monthly migraine days (MMDs) from baseline to the average of the first 6 months [ Time Frame: Completion of double blind treatment phase at 24 weeks ]
    To evaluate the effect of erenumab compared with placebo on the change in MMDs from baseline to the average of the 6 month (week 1 through week 24) double-blind treatment period (DBTP).

  5. Change in monthly average severity of migraine attacks from baseline (measured with a visual analogue scale) [ Time Frame: Baseline through week 12 of the double blind treatment phase ]
    To evaluate the effect of erenumab compared with placebo on the change from baseline in monthly average severity of migraine attacks to week 9 through week 12 (month 3) of the double-blind treatment period (DBTP). This will be measured in an electronic diary (eDiary) with a visual analogue scale.

  6. Change from baseline in migraine-related disability and productivity [ Time Frame: Baseline through week 12 of the double blind treatment phase ]
    To evaluate the effect of erenumab compared with placebo on the change from baseline in migraine-related disability and productivity as measured by the modified Pediatric Migraine Disability Assessment Questionnaire (modified PedMIDAS) to month 3 of the double-blind treatment period (DBTP).

  • History of migraine (with or without aura) for ≥ 12 months before screening according to the IHS Classification ICHD-3 (Headache Classification Committee of the International Headache Society, 2013) ICHD-3 specifications for pediatric migraine (subjects aged less than 18 years), should be considered for the diagnosis of migraine.
  • History of ≥ 15 headache days per month of which ≥ 8 headache days were assessed by the subject as migraine days per month in each of the 3 months prior to screening.
  • Migraine frequency: greater than or equal to 8 migraine days during the baseline phase based on the electronic diary (eDiary) calculations.

Key Exclusion Criteria:

  • History of cluster headache or hemiplegic migraine headache.
  • Chronic migraine with continuous pain, in which the subject does not have any pain free periods (of any duration) during the 1 month prior to screening.
  • No therapeutic response with greater than 3 medication categories for prophylactic treatment of migraine after an adequate therapeutic trial. No therapeutic response is defined as no reduction in headache frequency, duration, or severity after administration of the medication for at least 6 weeks at the generally-accepted therapeutic dose(s) based on the investigator's assessment.
  • History of suicidal behavior or the subject is at risk of self-harm or harm to others.
  • History of major psychiatric disorder. Subjects with anxiety disorder and/or mild major depressive disorder (Patient Health Questionnaire Modified for Adolescents [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. Subjects must have been on a stable dose within the 3 months before the start of the baseline phase.
