Brief summary: This study (Protocol No. E6011-J081-002) is a single-center, randomized, double-blind, placebo-controlled, single ascending dose (SAD) study to evaluate mainly the safety and tolerability of a single subcutaneous administration of E6011. A total of 32 subjects will be randomized into four cohorts (50, 100, 200 and 400 mg groups). Of eight subjects per cohort, six subjects will receive the single subcutaneous E6011 administration and two subjects will receive the single subcutaneous placebo administration.

Detailed description: This study consists of Screening Period, Observation Period, In-patient Period, and Follow-up Period. Screening assessments will be performed within 28 to 2 days before starting the study treatment, and Observation Period assessments will be performed on a day before starting the study treatment to confirm the eligibility of study subjects. The eligible subjects will be randomized into either E6011 arm or placebo arm using the drug allocation list prepared by the random code statistician. Each subjects dosing interval will be at least a 30-minutes.

Eligibility criteria: Inclusion criteria

1. Non-smoking Japanese male subjects aged greater than or equal to 20 to less than 45 years
2. BMI at screening is greater than or equal to 18.5 kg/m2 to less than 25.0 kg/m2
3. Males who have not had a successful vasectomy and their female partners must agree to practice highly effective contraception throughout the study period

Exclusion criteria

1. Has been treated with biologic product(s) (except for immunoglobulin)
2. Has received immunoglobulin or blood preparation within 6 months before the study treatment

4. Has a history of autoimmune disease or immunodeficiency
5. Has a history of clinically significant angioedema, hematemesis, anal hemorrhage, or hemoptysis
6. Has a history of acute myocardial infarction, cerebral infarction, cerebral hemorrhage, or arteriosclerosis obliterans
7. With gross hematuria, occult bleeding in urine of greater than or equal to 1+ and urine protein of greater than or equal to 1+, or either of greater than or equal to 2+ is found at screening
8. Has a clinically significant vasculitis (e.g., mononeuritis multiplex)
9.

10. Known to be positive for tuberculosis test (T-spot.TB Test or QuantiFERON TB Gold Test) at screening.
11. Treated with ethical drug (except for disinfectants, eye drops) within 4 weeks before the study treatment.
12. Treated with non-prescription drug (except for disinfectants, eye drops) within 2 weeks before the study treatment.
13. Has participated in another clinical trial and received an investigational drug or device within 16 weeks before the study treatment.
14. Received blood transfusion within 1 year, 400 mL or more whole blood donation within 12 weeks, or 200 mL or more whole blood donation within 4 weeks, or blood constituent donation within 2 weeks before the study treatment.
