a.The patient is a male or female 18 to 70 years of age, inclusive b.The patient signs and dates the informed consent document. c.The patient successfully 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 patient safety and patient compliance In addition, patients who do not complete the pivotal efficacy studies, and patients who complete the pivotal efficacy studies but do not wish to continue treatment during this long-term safety study, may enroll in this study for the purpose of evaluating ADAs, fremanezumab concentrations, and safety (adverse events and concomitant medications) approximately 7.5 months after administration of the last dose of the IMP. d.Women may be included only if they have a negative beta-human chorionic gonadotropin test at visit 1; are sterile or postmenopausal. e.Women of childbearing potential (WOCBP) whose male partners are potentially fertile (ie, no vasectomy) must use highly effective birth control methods for the duration of the study and for 7.5 months after discontinuation of IMP. f.Men must be sterile; or if they are potentially fertile/reproductively competent (not surgically [eg, vasectomy] or congenitally sterile), and their female partners are of childbearing potential, must use, together with their female partners, acceptable birth control methods for the duration of the study and for 7.5 months after administration of IMP. Definitions of WOCBP, sterile and postmenopausal women; male contraception; highly effective and acceptable birth control methods g.The patient must be willing to stop concomitant medications used in clinical practice for the prevention of CH for the duration of this study. (Note: Patients taking verapamil during the pivotal studies must begin tapering verapamil as soon as they enroll in this study, and they must be off verapamil within 1 month of beginning study participation.) h.The patient is in good health in the opinion of the investigator as determined by a medical and psychiatric history; medical examination; 12 lead ECG; and serum chemistry, hematology, coagulation, and urinalysis. i.The patient must be willing and able to comply with study restrictions to remain at the clinic for the required duration during the study period and to return to the clinic for the follow up evaluations, as specified in this protocol.
|
|
E.4 | Principal exclusion criteria |
a.Any finding in the 12-lead ECG performed as part of the EOT visit (visit 5) procedures for the pivotal studies considered clinically significant in the judgment of the investigator b.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) c.Hepatic enzymes (alanine aminotransferase and aspartate aminotransferase) >1.5 × the upper limit of the normal range (ULN) after confirmation in a repeat test or suspected hepatocellular damage that fulfills criteria for Hy’s law d.Serum creatinine >1.5 × the ULN or evidence of clinically significant renal disease in the judgment of the investigator

E.5 End points |
E.5.1 | Primary end point(s) |
Safety endpoints are as follows: •occurrence of adverse events throughout the study •changes from baseline (day 0 of the Phase 3 pivotal efficacy studies) in clinical laboratory (serum chemistry, hematology, coagulation, and urinalysis) test results •changes from baseline (day 0 of the Phase 3 pivotal efficacy studies) in vital signs (pulse, systolic and diastolic blood pressure, and oral temperature) measurements Note: Oxygen saturation will be measured in cases of suspected anaphylaxis and severe hypersensitivity. Respiratory rate will also be measured in these cases but not as a standard vital sign. •abnormal standard 12-lead electrocardiogram (ECG) findings •clinically significant changes in physical examination, including body weight •occurrence of injection site reactions (ie, erythema, induration, and ecchymosis) and injection site pain •occurrence of anaphylaxis and hypersensitivity reactions •use of concomitant medications during the study •suicidal ideation and behavior as measured by the electronic Columbia Suicide Severity Rating Scale (eC-SSRS)
