Primary Outcome Measures

Name	Time	Method
Change in Monthly Migraine Days (MMD) From Baseline to the Last 28 Days of Treatment Period.	From the 28-day baseline period to the last 28 days of the 84-days double-blinded treatment period.	Migraine with or without aura is defined according to the International Classification of Headache Disorders (ICHD)-3rd edition (beta version). Migraine headaches must be moderate or severe and lasting ≥30 minutes. When the patient falls asleep during migraine and wakes up without it, duration of the attack is reckoned until the time of awakening).

Secondary Outcome Measures

Name	Time	Method
The Change in HIT-6 From Baseline to Last 28 Days of Treatment	From the 28-day baseline period to the last 28 days of the 84-day treatment period.	HIT-6 - headache impact test - was designed to provide a global measure of adverse headache impact. Score range is 36-78, Score ≥ 60 - a very severe impact on life, scored ≤ 49 little to no impact on life. The percent responders were calculated as follows: the change from baseline score divided by the score at the baseline minus 36.
The Number of Participants With 100% Improvement in Mean MMD in the Last 28 Days Double-blinded Treatment Period.	From the 28-day baseline period to the last 28 days of the 84-day treatment period.
The Number of Participants With More Than 75% Improvement in the Mean Monthly Migraine Days (MMDs)	From the28-day baseline period to the last 28 days of the 84-day treatment period.
Mean Monthly Acute Migraine Medication Treatment Days Change From Baseline to Last 28 Days of Treatment	From the 28-day baseline period to the last 28 days of the 84-day treatment period.
The Number of Participants With More Than 50% Improvement in the Mean Monthly Migraine Days (MMDs)	From the 28-day baseline period to the last 28 days of the 84-days double-blinded treatment period.	MMD stands for change in Monthly Migraine Days from 28-day baseline to the last 28 days of the double-blind treatment period
