Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in the Frequency of Headache Days during 28-Day Period Ending with Week 24
Time Frame: Baseline, 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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in the Frequency of Headache Days during 28-Day Period
Time Frame: Baseline, Weeks 4, 8, 12, 16 and 20
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
Change from Baseline in the Frequency of Migraine/Probable Migraine Days during 28-Day Period
Time Frame: Baseline, Weeks 4, 8, 12, 16, 20 and 24.
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.
Change from Baseline in the Number of Moderate/Severe Headache Days during 28-Day Period
Time Frame: Baseline, Weeks 4, 8, 12, 16, 20 and 24
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
Change from Baseline in Total Cumulative Hours of Headache Days during 28-Day Period
Time Frame: Baseline, Weeks 4, 8, 12, 16, 20 and 24
