SECONDARY outcome

Timeframe: Baseline (28 days before randomization) and Continuous treatment period (Day 1 up to Day 225)

Population: Full analysis set (FAS) included all participants randomly assigned to study treatment excluding those who did not meet eligibility criteria, did not receive study treatment at all and did not provide any efficacy data after randomization.

As per 24-hour rule, if symptom of pain because of migraine continues for more than 24 hours, it should be considered as 2 or more migraine attacks considering the maximum duration up to 24 hours. If interval between the latest migraine attack (ending time) and previous migraine attack (onset time) was less than 24 hours, 2 migraine attacks were considered as 1 migraine attack. If the onset of the migraine was prevented by a rescue drug it was considered as 1 migraine attack even if the aura had started.

Migraine headache day was defined as a calendar day with any occurrence of migraine headache pain of at least 30 minutes in duration. Average was calculated as total number of monthly headache days divided by total number of days of assessment and multiplied by 28, where a month was considered to last 28 days.

If aura of migraine, migraine attack or non-migraine headache attack occurred in study, these rescue drugs were permitted:analgesics, non-steroidal anti-inflammatory drugs (NSAIDs),ergotamines,triptans,antiemetics. Drugs with restricted treatment days of less than (\<) 15 days per month (28 days):analgesics, NSAIDs,combination of rescue drugs and those with \<10 days per month:triptans,ergotamines, opioids,combination analgesics. Average calculated as total number of monthly rescue-drug treatment days divided by the total number of days of assessment and multiplied by 28, where a month = 28 days.

Population: The FAS included all participants randomly assigned to study treatment excluding those who did not meet eligibility criteria, did not receive study treatment at all and did not provide any efficacy data after randomization.

Responders were defined as participants who had a 50 percent or more reduction in frequency of migraine attacks. Migraine is common disabling headache disorder with 2 subtypes: migraine without aura (at least 5 attacks lasting 4-72 hours with at least 2 characteristics: unilateral location, pulsating quality, moderate/severe pain or aggravation by/causing avoidance of routine physical activity and either nausea/vomiting or photophobia and phonophobia) and migraine with aura (attack with reversible focal neurological symptoms that develop over 5-20 minutes and last for less than 60 minutes).

Population: The FAS included all participants randomly assigned to study treatment excluding those who did not meet eligibility criteria, did not receive study treatment at all and did not provide any efficacy data after randomization. Here 'n' signifies those participants who were evaluable for this measure at given time points.

The SF-36 is a standardized survey evaluating 8 domains (consisting of 2 components; physical and mental) of functional health and well being: physical and social functioning, physical and emotional role (role-physical, role-emotional) limitations, bodily pain, general health, vitality, mental health. The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning). Final evaluation (FE) was done at Day 225 or at discontinuation.
