Efficacy and Safety of Erenumab in Pediatric Participants With Episodic Migraine

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 456 participants (376 adolescents and up to 80 children).
