Any finding that, in the judgment of the investigator, is a clinically significant abnormality, including physical examination and vital signs as blood pressure and heart rate (abnormal may be repeated up to 3 times for confirmation). d. Any finding that, in the judgment of the investigator, is clinically significantly abnormal, including hematology, blood chemistry, coagulation, or urinalysis results. (Note: Abnormal tests may be repeated for confirmation.) Patient has a positive cotinine test (>300 ng/mL) at screening or check-in. e. Patient with evidence or medical history of clinically significant psychiatric issues including any suicide attempt or any significant risk of suicide (any suicidal ideation in the past 6 months). f. History of clinically significant cardiovascular disease or vascular ischemia (such as myocardial, neurologic [eg, cerebral ischemia], peripheral extremity ischemia, or other ischemic event) or thromboembolic events (arterial or venous thrombotic or embolic events), such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis, or pulmonary embolism. g. Ongoing infection, or known history of human immunodeficiency virus (HIV) infection, tuberculosis, or chronic hepatitis B or C. h. Any finding in the baseline 12-lead ECG considered clinically significant in the judgment of the investigator i. Any past or current history of cancer. j. Any pregnant female. k. History of hypersensitivity reactions to injected proteins, including monoclonal antibodies, or any other component of the formulation. l. The patient has participated in another study of an IMP (or a medical device) within the previous 30 days (or 90 days for biologics) or 5 half-lives of the IMP, whichever is longer, or is currently participating in another study of an IMP (or a medical device). m. Any prior exposure to a monoclonal antibody targeting the CGRP pathway (AMG 334, ALD304, LY2951742, TEV-48125). n. Hepatic enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [ALP]) more than 1.5 times the upper limit of normal (ULN) for that age after confirmation in a repeat test. o. Serum creatinine >1.5 times the ULN, clinically significant proteinuria (urine dipstick +4), or evidence of renal disease at screening. p. History of alcohol or drug abuse. q. The patient cannot participate or successfully complete the study, in the opinion of the investigator, for any of the following reasons: - The patient is mentally or legally incapacitated, or unable to give assent or consent for any reason. - The patient is in custody due to an administrative or a legal decision, or under tutelage, or being admitted to a sanitarium or social institution. - The patient’s parent(s)/legal guardian(s) and/or the patient cannot be contacted in case of emergency. The patient must be accompanied by the parent(s)/legal guardian(s) during patient visit. - The patient has any other condition, which, in the opinion of the investigator, makes the patient inappropriate for inclusion in the study. - The patient is a relative of a study center or sponsor employee who is directly involved in the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
The following pharmacokinetic parameters will be evaluated to support the primary objective of the study: - Maximum observed concentration (Cmax) - AUC from time 0 to the time of the last measurable IMP concentration (AUC0-t) - time to maximum observed plasma drug concentration (tmax) - AUC from time 0 to infinity (AUC0-∞) - percentage extrapolated AUC (%AUCext) - apparent plasma terminal elimination rate constant (λz) and associated elimination half-life (t½) - apparent volume of distribution (Vz/F) - apparent clearance (CL/F) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The safety endpoints are - Occurrence of adverse events throughout the study - Vital signs (blood pressure, respiratory rate, body temperature, and pulse) measurements - Triplicate 12-lead electrocardiogram (ECG) findings. First ECG will be used for bedside safety assessment and the triplicate ECGs will be sent for central analysis. - Physical examination - Clinical laboratory (serum chemistry, hematology, urinalysis, and coagulation tests) - Tolerability at the injection site including clinical findings (ie, pain, erythema, induration, and ecchymosis) - Concomitant medication usage |
