Study of Recombinant Human Coagulation Factor VIII-Fc Fusion Protein (FRSW107) On-Demand Treatment
The indication for this product is to control bleeding in patients with hemophilia A (congenital deficiency of factor VIII). The primary objective: Evaluation of the efficacy of recombinant human coagulation factor VIII-Fc fusion protein for injection (FRSW107) as an on-demand treatment in previously treated patients with severe hemophilia A. Secondary objectives: Evaluation of the safety and immunogenicity of FRSW107 as an on-demand therapy in previously treated patients with severe hemophilia A. Evaluate the on-demand treatment's PK profile of FRSW107 in previously treated patients with severe hemophilia A based on population pharmacokinetic (PopPK) methods ; preliminarily investigate the exposure-response (E-R) relationship of FRSW107 on-demand treatment in these patients if data permit.
