A Study to Explore the Long-Term Safety and Efficacy of Fremanezumab (TEV-48125) for the Prevention of Cluster Headache

Study Overview
=================
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.

Eligibility Criteria
-----------------
Inclusion Criteria: The participant completes either the Phase 3 pivotal study for ECH (Study TV48125-CNS-30056) or the Phase 3 pivotal study for CCH (Study TV48125-CNS-30057) without important protocol deviations related to participant safety and participant compliance.
