Eligibility Criteria
Key Inclusion Criteria:
- The activity of the coagulation factor VIII (FVIII:C) < 1%. Less than 6 years old
Patients previously treated with FVIII concentrate (s) for a minimum of 50 exposure
days (EDs) prior to study entry. 6 years old to 12 years old Patients previously
treated with FVIII concentrate (s) for a minimum of 150 exposure days (EDs) prior to
study entry.
- Normal prothrombin time or INR < 1.3.
- Negative lupus anticoagulant.
Key Exclusion Criteria:

or hamster origin heterologous proteins).
- History of hypersensitivity or anaphylaxis associated with any FVIII or II
immunoglobulin administration.
- Current FVIII inhibitor-positive or history of FVIII inhibitor-positive.
- Other coagulation disorder(s) in addition to hemophilia A.
- Infusion of any products containing FVIII within 72 h prior to administration.
- Significant hepatic or renal impairment (ALT and AST > 2×ULN; serum bilirubin level >
2 × upper limit of normal (ULN), BUN > 2×ULN, Cr > 2.0 ULN).
- One or more clinically significant tests for Human Immunodeficiency Virus (HIV),
Antisyphilitic spirulina (TPHA) and Hepatitis C Virus (HCV) Antibody.
- Patients who received any anticoagulant or antiplatelet therapy within one week prior
screening or need to receive an anticoagulant or antiplatelet therapy during the
period of clinical trials.
- Patients having major surgery or receiving blood or bood components transfusion within
4 weeks prior screening or having planned major surgery schedule during the study.
- Patients who previously participated in the other clinical trials within one month
prior to administration.
- Any life-threatening disease or condition which, according to the investigator's
judgment, could not benefit from the trial participation.
- Patient who is considered by the other investigators not suitable for clinical study.
