  • Outcome Measures

    Primary Outcome Measures

    1. Total response rate to treatment (OR) Total response rate to treatment [During 8 weeks]

      The proportion of patients achieving OR defined as factor VIII level> 50% and no bleeding events without bypass treatments for 24 hours will be evaluated.

    Secondary Outcome Measures

    1. the proportion of patients with complete remission (CR) [During 8 weeks]

      The proportion of patients achieving CR , which is defined as titer FVIII inhibitor lower than 0.6 Bethesda unit, factor VIII level> 50% and no bleeding events without bypass treatments for 24 hours , will be evaluated

    2. the proportion of patients with partial remission rate (PR) [During 8 weeks]

      The proportion of patients achieving PR, which is defined as titer FVIII inhibitor higher than 0.6 Bethesda unit and factor VIII level> 50%, will be evaluated.

    3. time to CR [During 8 weeks]

      The time for patients to reach complete remission

    4. The proportion of patients remaining in CR during 24 weeks [During 24 weeks]

      The proportion of patients who reached CR and remain in CR during 24 weeks of follow -up time

    5. The proportion of patients relapse after reaching CR during 24 weeks [During 24 weeks]

      The proportion of patients who reached CR and relapse during 24 weeks of follow -up time

    6. Safety outcome [From start of the treatment until the end of 24 weeks in the follow-up period]

      Adverse events will be collected
