Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objectives of the study are to evaluate the efficacy of Recombinant Human Coagulation Factor VIII-Fc Fusion Protein for Injection (FRSW107) in the Prevention and Treatment of Bleeding in patients with hemophilia A.

The secondary objectives are to evaluate the efficacy and safety of Recombinant Human Coagulation Factor VIII-Fc Fusion Protein for Injection (FRSW107) in the prevention and treatment of bleeding episodes, to investigate the quality of life in patients who used the FRSW107.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm 1-on demand treatment

Part A-Participants will receive on-demand treatment with Recombinant Human Coagulation Factor VIII-Fc Fusion Protein for Injection for 6 months.

Group Type EXPERIMENTAL

Recombinant Human Coagulation Factor VIII-Fc Fusion Protein for Injection

Intervention Type DRUG

Participants received on-demand treatment, doses range from 30 IU/kg to 50 IU/kg, or doses divided on the discretion of the Investigator.

Arm 2- prophylaxis treatment

Part B-Participants will receive prophylaxis treatment with Recombinant Human Coagulation Factor VIII-Fc fusion for 6 months.

12 Participants of them will receive PK assessment at ED1 and ED35(Participants will be tested for PK assessment at timepoints throughout the study based on exposure days (ED). One ED is equivalent to a 24 hours period in which drug is dosed.),measured by one-stage assay, they would not be given prophylaxis treatment until the completion of PK blood collection.

Group Type EXPERIMENTAL

Recombinant Human Coagulation Factor VIII-Fc Fusion Protein for Injection

Intervention Type DRUG

Participants received prophylaxis treatment at 50 IU/kg every three days.

Inclusion Criteria

* 1)Male, aged 12 to 60 years
* 2)Severe hemophilia A. The activity of the coagulation factor VIII (FVIII:C) \< 1%, and previously treated with FVIII concentrate (s) for a minimum of 150 exposure days (EDs) prior to study entry.
* 3\) No history of a positive inhibitor test (\< 0.6 BU) or clinical signs of decreased response to FVIII administrations within 2 years before the test or during the screening period. No Family history of inhibitors.
* 4\) Non-immune deficiency, with a certain immune capacity (CD4 \> 200/μL)
* 5\) Platelet count \> 100,000 platelets/μL.
* 6\) Normal prothrombin time or INR \< 1.3.
* 7\) Normal previous results of vWF antigen examination.
* 8\) Negative lupus anticoagulant.
* 9\) the patient has a detailed record of bleeding events for at least 6 months (the subject can be admitted to the on-demand treatment group with spontaneous bleeding ≥3 times within 6 months).
* 10\) Capable of understanding and willing to comply with the conditions of the protocol have read (patient and/or guardian).

Exclusion Criteria

* 1\) Hypersensitive to any of the excipients of the test materials (e.g. allergic to murine or hamster origin heterologous proteins).
* 2\) History of hypersensitivity or anaphylaxis associated with any FVIII or II immunoglobulin administration.
* 3\) Other coagulation disorder(s) in addition to hemophilia A.
* 4\) Patients with severe heart disease, including myocardial infarction, heart failure (III or higher level).
* 5\) Clinically significant of other systematic diseases: alcoholism, drug abuse, mental disorders and mental retardation.
* 6\) Significant hepatic or renal impairment (ALT and AST \> 2×ULN; serum bilirubin level \> 3 × upper limit of normal (ULN), BUN \> 2×ULN, Cr \> 176.8µmol/L).
* 7\) 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.
* 8\) Patients having major surgery or receiving blood or blood components transfusion within 4 weeks prior screening or having planned major surgery schedule during the study.
* 9\) Patients who previously participated in the other clinical trials within 1 month prior screening.
* 10\) One or more clinically significant tests for Hepatitis B Virus Surface Antigen, Human Immunodeficiency Virus (HIV), Antisyphilitic spirulina (TPHA) and Hepatitis C Virus (HCV) Antibody.
* 11\) Any life-threatening disease or condition which, according to the investigator's judgment, could not benefit from the trial participation.
* 12\) Patient who is considered by the other investigators not suitable for clinical study.
