Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Frequency of Headache Days
Time Frame: Baseline, Week 24
Mean change from baseline in frequency (number) of headache days during the 28 day period ending with Week 24. Headache day defined as a calendar day [00:00 to 23:59] for which the patient reported >= 4 continuous hours of headache.
Baseline, Week 24

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Frequency of Headache Episodes
Time Frame: Baseline, Week 24
Mean change from baseline in frequency (number) of headache episodes during the 28 day period ending with Week 24. Headache episode defined as patient-reported headache with a start and stop time indicating that the pain lasted >= 4 continuous hours.
Baseline, Week 24
Change in Total Cumulative Hours of Headache Occurring on Headache Days
Time Frame: Baseline, Week 24
Mean change from baseline in total cumulative hours of headache occurring on headache days during the 28 day period ending with Week 24. Headache day defined as a calendar day [00:00 to 23:59] when the patient reported >= 4 continuous hours of headache.
Baseline, Week 24
Change in Frequency of Moderate/Severe Headache Days
Time Frame: Baseline, Week 24
Mean change from baseline in frequency (number) of moderate/severe headache days during the 28 day period ending with Week 24. Those calendar days with >= 4 continuous hours of headache were selected. As per the patient diary, all headache episodes occurring during those days with a maximum severity of moderate or severe were counted.
Baseline, Week 24
Change in Frequency of Migraine/Probable Migraine Headache Days
Time Frame: Baseline, Week 24
Mean change from baseline in frequency (number) of migraine/probable migraine headache days during the 28 day period ending with Week 24. Headache day defined as a calendar day with >= 4 continuous hours of headache meeting the ICHD-II criteria for migraine or probable migraine.
Baseline, Week 24
Percentage of Patients With Severe HIT-6 Impact Category Scores
Time Frame: Week 24
Percentage of patients with a severe (60-78) score on the Headache Impact Test (HIT-6) Questionnaire during the 28 day period, ending with Week 24. The HIT-6 consisted of 6 questions about headache and impact on the patient's health and well-being. Answers for each question ranged from 6=Never, 8=Rarely, 10=Sometimes, 11=Very Often, and 13=Always. The total scores ranged from 36-49 (Little or No Impact), 50-55 (Some Impact), 56-59 (Substantial Impact) and 60-78 (Severe Impact).
