Eligibility Criteria

Inclusion Criteria

•Healthy Chinese male subjects, aged 20-45 years inclusive at the time of screening
•Chinese subjects must have Chinese parents and grandparents, all of whom were born in China
•A body mass index (BMI) between 19 and 24 kilograms per height in meters squared (kg/m\^2), inclusive

Exclusion Criteria

•Any history or presence of a clinically significant disorder, or any other condition or disease which in the judgement of the investigator would place the subject at undue risk; interfere with absorption, distribution, metabolism, and excretion of emicizumab; or interfere with the ability of the subject to complete the study
•Major illness within 1 month prior to dosing, and/or any condition which could relapse during or immediately after the study
•Use of any prescribed or over-the-counter (OTC) medication or herbal medicine taken within 14 days prior to dosing or within 5 times the elimination half-life of the medication prior to dosing (whichever is longer), with some exceptions
•Any significant donation/loss of blood or plasma (greater than 450 milliliters) within the 3 months prior to dosing
•Regular smoker with consumption of more than 10 cigarettes per day or the equivalent amount of tobacco

Primary Outcomes

Maximum Observed Plasma Concentration (Cmax) of Emicizumab
