A Multicenter, Randomized, Double-Blind, Double-Dummy, Placebo-Controlled, Parallel-Group Study Comparing the Efficacy and Safety of 2 Dose Regimens (Intravenous/Subcutaneous and Subcutaneous) of TEV-48125 Versus Placebo for the Prevention of Epidosic Cluster Headache
A Multicenter, Randomized, Double-Blind, Double-Dummy, Placebo-Controlled, Parallel-Group Study Comparing the Efficacy and Safety of 2 Dose Regimens (Intravenous/Subcutaneous and Subcutaneous) of TEV-48125 Versus Placebo for the Prevention of Epidosic Cluster Headache
This is a 13-week, multicenter, randomized, double-blind, double-dummy, placebo-controlled, parallel-group study to compare the efficacy and safety of 2 dose regimens of TEV-48125 (Fremanezumab) versus placebo in adult participants for the prevention of ECH.
Inclusion Criteria:
The participant has a history of ECH according to the International Classification of Headache Disorders - 3 beta criteria (Headache Classification Committee of the International Headache Society [IHS] 2013) for ≥12 months prior to screening.
The participant has a total body weight of ≥45 kg (99 lbs.)
The participant is in good health in the opinion of the investigator
Women of childbearing potential (WOCBP) whose male partners are potentially fertile (that is, no vasectomy) must use highly effective birth control methods for the duration of the study.
Men must be sterile, or if they are potentially fertile/reproductively competent (not surgically [for example, vasectomy] or congenitally sterile) and their female partners are of childbearing potential, must agree to use, together with their female partners, acceptable birth control for the duration of the study.
If a participant is receiving Botox, it should be in a stable dose regimen, considered as having ≥2 cycles of Botox prior to screening. The participant should not receive Botox during the run-in period up to the evaluation period (4 weeks) where the primary endpoint is evaluated.
Exclusion Criteria:
The participant has used systemic steroids for any medical reason (including treatment of the current CH cycle within ≤7 days prior to screening The participant has used an intervention/device (for example, scheduled nerve blocks) for headache during the 4 weeks prior to screening.
The participant has clinically significant hematological, renal, endocrine, immunologic, pulmonary, gastrointestinal, genitourinary, cardiovascular, neurologic, hepatic, or ocular disease at the discretion of the investigator.

The participant has a history of prior exposure to a monoclonal antibody targeting the calcitonin gene-related peptide (CGRP) pathway (AMG 334, ALD304, LY2951742, or fremanezumab). If participant has participated in a clinical study with any of these monoclonal antibodies, it has to be confirmed that the participant received placebo in order to be eligible for this study.

The participant has an active implant for neurostimulation used in the treatment of CH.
