Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Monthly Migraine Days (MMDs) in Children 6 to 11 Years Old With Migraine.

    The primary efficacy endpoint was the change in rate of the MMDs relative to the Prospective Baseline Period (PBP). The 28-day rate of MMDs was calculated as the ratio of the # days of migraine during the last 4 weeks of PBP and the # days with non-missing headache record in the electronic diary during the last 4 weeks of the 20-week double-blind Treatment Phase, x 28. The primary outcome measure was recorded on headache electronic diary uploaded on a Patient Reported Outcome (ePRO) application. The electronic diary will serve as the primary tool to collect daily headaches information.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Otherwise, healthy male or female (6 to 11 years of age at the time of screening) with a history of migraine with or without aura for at least 6 months prior to screening, 3-12 migraine episodes and no more than 14 headache days (migraine and non-migraine) per month during the 3 months prior to Screening and during the 28-day Prospective Baseline Period, a PedMIDAS Disability score of ≥20 and ≤139 and weight at least 20 kg and no more than 60 kg.

You may not qualify if:

  • Subjects with chronic migraine (\>14 headache days per month), cluster headaches, or migraine aura without headache and who are unable to distinguish migraines from other headache types.
  • Subjects with more than 14 headache days during the 28-day Prospective Baseline Period
  • Have taken any disallowed migraine preventive medication including TPM within 14 days prior to the start of the Prospective Baseline Period; or used onabotulinumtoxinA (Botox®) within 3 months prior to Screening.
  • Failure to respond to topiramate prophylaxis therapy (2 to 3 mg/kg/day) for a minimum of 3 months, or those who have previously discontinued TPM due to AEs within 6 months prior to Screening.
  • Failure to more than 2 adequate clinical trials of an established prophylactic antimigraine regimen within 6 months prior to Screening.
  • Current use of antipsychotics, antimanics, barbiturates, benzodiazepines amitriptyline, lithium, valproic acid, tricyclic antidepressants, AEDs, calcium channel blockers, sedatives, SSRIs, NSRIs, CGRP receptor antagonists, CBD oil, herbal preparations/supplements such as feverfew or St John's wort and/or any medications that could impair or decrease thinking and concentration.
  • Overuse of analgesic or migraine-specific agents for acute treatment of migraine (\>10 treatment days/month of ergot-containing medications or triptans; or \>15 treatment days/month with simple analgesics (including non steroidal anti-inflammatory drugs \[NSAIDs\]), or use of narcotics.
  • Use of non-pharmacologic complementary and alternative prophylactic approaches for migraine prevention, such as neuromodulation, acupuncture, behavioral interventions, spinal manipulation, occipital nerve block and neurofeedback.
  • Diagnosis of psychiatric disorder (e.g., psychosis, bipolar disorder, major depression, generalized anxiety disorders), or documented developmental delays or impairments (e.g., autism, cerebral palsy, or mental retardation).
  • Subjects with seizures or a history of seizure-like events.
  • Known history of visual field defects, neurological disorder or structural disorder of the brain from birth; head trauma or previous CNS surgery.
  • Evidence of active suicidal ideation and/or suicidal behaviors 6 months before screening, pregnancy, active liver disease or abnormal kidney function.
