Further study details as provided by Novartis:

Primary Outcome Measures:
  • Percentage of patients with a 50% response in the reduction of Monthly Migraine Days (MMD) [ Time Frame: The last month (Month 3) of the Double-Blind Treatment Epoch (DBTE) ]
    Assessed via patient report collected in the headache e-diary.

Secondary Outcome Measures:
  • Change in the number of monthly migraine days (MMDs) from baseline to month 3 [ Time Frame: Baseline, the last month (Month 3) of the Double-Blind Treatment Epoch (DBTE) ]
  • Change in the Migraine Physical Function Impact Diary (MPFID) "impact on everyday activities" domain score from baseline to month 3 [ Time Frame: Baseline, month 3 of the DBTE ]
  • Change in the MPFID "physical impairment" domain score from baseline to month 3 [ Time Frame: Baseline, month 3 of the DBTE ]
  • Change in the number of monthly acute migraine-specific medication treatment days [ Time Frame: Baseline, last month (Month 3) of the Double-Blind Treatment Epoch (DBTE) ]
  • Percentage of patients with a 75% response [ Time Frame: Baseline, last month (Month 3) of the Double-Blind Treatment Epoch (DBTE) ]
    Assessed via patient report collected in the headache e-diary.

  • Percentage of patients with a 100% response [ Time Frame: Baseline, last month (Month 3) of the Double-Blind Treatment Epoch (DBTE) ]
    Assessed via patient report collected in the headache e-diary.
