    On July 12, the CDE official website showed that Sanofi's injection-use recombinant human coagulation factor VIII Fc-von Willebrand factor-XTEN fusion protein (efanesoctocog alfa, rFVIIIFc-VWF-XTEN, BIVV001) was approved by CDE as a breakthrough therapy.
    suitable for adults and children with type a hemophilia

    Due to the lack or insufficiency of a certain coagulation factor in the body, the coagulation time is prolonged and the patient has the symptoms of easy bleeding
    .

    Hemophilia A is a genetic disease in which FVIII is missing due to mutations in the gene encoding FVIII
    .

    At present, the common treatment for hemophilia A is regular infusion of FVIII.
    However, patients usually need to receive FVIII infusions 3-4 times a week, which brings great inconvenience to their lives
    .

    Sanofi BIVV001 is a new type of coagulation factor VIII replacement therapy under development.
    It consists of a recombinant FVIII Fc fusion protein molecule coupled to a specific region of VWF (FVIII binds to the D'D3 domain) and two XTEN unstructured peptides.
    After allowing hemophilia A patients to receive an injection, they can obtain nearly normal FVIII factor activity levels for most of the week
    .

    According to currently released clinical trial data, the fusion protein BIVV001 can extend the half-life of factor VIII by three to four times.
    On day 7, the patient’s factor VIII activity is still at a high level sufficient to prevent bleeding episodes
    .

    At the same time, BIVV001 showed good tolerance, and no FVIII inhibitor was detected within 28 days after administration
    .

    Currently, there are approximately 136,000 patients in China
    .

    If the patient bleeds repeatedly and is not treated in time, it will cause joint deformities and even disability, and severe bleeding symptoms may even be life-threatening
    .

    A new study released by researchers at McMaster University shows that more than 1.
    125 million men worldwide suffer from hemophilia, and 418,000 of them suffer from severe hemophilia
    .

    BIVV001 has now entered a phase III clinical trial, aiming to evaluate the efficacy and safety of BIVV001 in previously treated patients with severe type A blood (n=150)
