What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Change From Baseline in the Weekly Average Number of Cluster Headache (CH) Attacks During the 4-Week Period After Administration of the First Dose of the IMP | A CH attack was defined as a severe or very severe unilateral orbital, supraorbital, and/or temporal pain lasting 15 to 180 minutes with either or both of the following 2 categories: 1) at least 1 of the following symptoms or signs, ipsilateral to the headache: -conjunctival injection and/or lacrimation; -nasal congestion and/or rhinorrhea; -eyelid edema; -forehead and facial sweating; -forehead and facial flushing; -sensation of fullness in the ear; -miosis and/or ptosis. 2) a sense of restlessness or agitation. Least Squares (LS) mean calculated using analysis of covariance (ANCOVA) model with baseline preventive medication use (yes or no), sex, region (United States [US]/Canada or other), and treatment as fixed effects and the baseline number of CH attacks as a covariate. Change from baseline in the overall weekly average number of CH attacks during the 4-week period after administration of the first dose of study drug (based on Week 0 to 4 data) is reported. | Baseline (Week 0), up to Week 4 |
