Brief Summary
This is a 68-week study to evaluate the long-term safety and efficacy of fremanezumab in participants with cluster headache (CH). Participants who complete the pivotal studies TV48125-CNS-30056 (NCT02945046) and TV48125-CNS-30057 (NCT02964338) and enroll into the current study will visit the investigational center for investigational medicinal product (IMP) administration, safety and efficacy assessments, and blood and urine collections for pharmacokinetics, immunogenicity (anti-drug antibodies \[ADAs\]), and biomarker analyses. Participants will return to the investigational center for a follow-up visit to evaluate ADAs, fremanezumab concentrations, biomarkers, and safety (adverse events and concomitant medications) approximately 7.5 months after the last dose of IMP.

Outcome Measures
Primary Outcomes (12)
Number of Participants With Adverse Events (AEs)
An AE was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Relationship of AE to treatment was determined by the Investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent the previously listed serious outcomes.
