Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline in the Frequency of Headache Days during 28-Day Period Ending with Week 24	Mean change from Baseline (28-days prior to first treatment) in frequency (number) of headache days during the 28-day period ending with Week 24. A headache day was defined as a calendar day [00:00 to 23:59] for which the participant reported = 4 continuous hours of headache per patient diary.	Baseline, Week 24
Secondary	Change from Baseline in the Frequency of Headache Days during 28-Day Period	Mean change from Baseline (28-days prior to first treatment) in frequency (number) of headache days during the 28-day period ending with Weeks 4, 8, 12, 16 and 20. A headache day was defined as a calendar day [00:00 to 23:59] for which the participant reported = 4 continuous hours of headache per patient diary.	Baseline, Weeks 4, 8, 12, 16 and 20
Secondary	Change from Baseline in the Frequency of Migraine/Probable Migraine Days during 28-Day Period	Mean change from Baseline (28-days prior to first treatment) in frequency (number) of migraine or probable migraine episodes during the 28-day period ending with Weeks 4, 8, 12, 16, 20 and 24. A Migraine or Probable Migraine day was defined as a calendar day [00:00 to 23:59] for which the patient reported = 4 continuous hours of a migraine or probable migraine episode as per the patient diary.	Baseline, Weeks 4, 8, 12, 16, 20 and 24.
Secondary	Change from Baseline in the Number of Moderate/Severe Headache Days during 28-Day Period	Mean change from Baseline (28-days prior to first treatment) in frequency (number) of headache days during the 28 day period ending with Weeks 4, 8, 12, 16, 20 and 24. A moderate/severe headache day is defined as a day (00:00 to 23:59) when a participant reported 4 or more continuous hours of headache and reported a maximum severity of moderate or severe per patient diary among all headache episodes that occurred on that day.	Baseline, Weeks 4, 8, 12, 16, 20 and 24
Secondary	Change from Baseline in Total Cumulative Hours of Headache Days during 28-Day Period	Mean change from Baseline (28-days prior to first treatment) in the total cumulative hours of headache days during the 28-day period ending with Weeks 4, 8, 12, 16, 20 and 24. A headache day is defined as a day (00:00 to 23:59) with 4 or more continuous hours of headache per patient diary.	Baseline, Weeks 4, 8, 12, 16, 20 and 24
