NCT07406139

Brief Summary

This study is a multicenter, prospective, single-arm exploratory clinical trial designed to evaluate the efficacy and safety of prothrombin complex concentrate (PCC) in the treatment of bleeding episodes in patients with hemophilia A with inhibitors. All participants received on-demand PCC therapy during bleeding episodes, with dosing adjusted by investigators according to the type of bleeding. The recommended dose was 50 IU/kg per infusion, administered every 8-12 hours, with a maximum total daily dose not exceeding 150 IU/kg. If no effective hemostasis was achieved within 24 hours, investigators could decide to add other hemostatic agents or switch to alternative treatments.

Outcome Measures

Primary Outcomes (1)

  • Efficacy of prothrombin complex concentrate (PCC) in the treatment of bleeding episodes in patients with hemophilia A with inhibitors.

    Hemostatic Efficacy Rate: Bleeding symptoms were evaluated at 8 hours and 24 hours after treatment. The assessment of hemostatic response included four categories: excellent, good, moderate, and ineffective.

    From enrollment to the end of treatment at 24 hours

Secondary Outcomes (1)

  • To evaluate the improvement score of bleeding symptoms and signs within 24 hours after the first infusion of prothrombin complex concentrate (PCC) for each bleeding episode in patients with hemophilia A with inhibitors.

    From enrollment to the end of treatment at 24 hours
