Brief summary: The purpose of the study is to assess the safety, pharmacokinetics (what the body does to the drug) and immunogenicity (ability of a particular substance to provoke an immune response in the human body) of CR8020 in japanese healthy participants

Detailed description: This study is a randomized (study medication is assigned by chance), double-blind (neither physician nor participant knows the treatment that the participant receives), placebo-controlled (placebo comparator is compared with the study medication to evaluate safety profile of the study medication in clinical study), single-dose study in Japanese healthy adult male participants. The study will include screening phase (28 to 2 days prior to the study medication administration), treatment phase (Study medication will be administered on Day 1), and follow-up phase (up to 99 days). Twelve participants will be randomly assigned to CR8020 50 mg/kg or placebo groups in a 2:1 ratio and receive an assigned treatment on Day 1. Safety will be assessed by evaluating adverse events, clinical laboratory tests, 12-lead Electrocardiogram, vital signs, and physical examination. Total maximum duration of participation of an individual participant will be 127 days.

Eligibility criteria: Inclusion Criteria:

* Have signed an informed consent document
* Body mass index between 18 and 30 kg/m2, with body weight greater than or equal to 50 kg at screening
* Must agree to use an adequate contraception method (eg, vasectomy, double-barrier, partner using effective contraception) and to not donate sperm from the study drug administration until Day 99
* Blood pressure between 90 and 140 mmHg systolic, inclusive, and no higher than 90 mmHg diastolic at screening
* Non-smoker or participant who smokes no more than 10 cigarettes, or 2 cigars, or 2 pipes of tobacco per day for at least 6 months before the study drug administration

Exclusion Criteria:

* History of or current clinically significant medical illness determined by the investigators including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, and coagulation disorders
* Clinically significant abnormal values for hematology, clinical chemistry or urinalysis
* Clinically significant abnormal physical examination, vital signs or 12-lead electrocardiogram
* A diagnosis of influenza infection or any constellation of clinical symptoms consistent with influenza infection within 14 days before the study drug administration is scheduled
* Participants with a fever of over 37.5°C on Day -1 or at predose
