A Multicenter, Double-Blind, Double-Dummy Study to Explore the Long-Term Safety and Efficacy of TEV-48125 for the Prevention of Cluster Headache
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.
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.
Prior to 15 June 2018, participants from the ECH study and the CCH study were enrolled. After 15 June 2018, only participants who participated in the ECH study (Study TV48125-CNS-30056) will be enrolled for active treatment.
In addition, participants who do not complete the pivotal efficacy studies, and participants who complete the pivotal efficacy studies but will not continue treatment during this long-term safety study, will be offered to enroll in this study for the purpose of evaluating ADAs, and safety (adverse events and concomitant medications) approximately 7.5 months after administration of the last dose of the IMP.
Exclusion Criteria:
Any finding that, in the judgment of the investigator, is a clinically significant abnormality, including serum chemistry, hematology, coagulation, and urinalysis test values (abnormal tests may be repeated for confirmation)
