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:

• Hypersensitive to any of the excipients of the test materials (e.g. allergic to murine 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.
