NCT04061109

Brief Summary

This is a multi-center, open-label, single-arm trial to evaluate the efficacy and safety of Recombinant Coagulation Factor VIII in patients with hemophilia A . Recombinant Coagulation Factor VIII is prophylactic administrated 25 - 35 IU/kg once every other day or three times per week which should be continuous for 24 weeks.

Outcome Measures

Primary Outcomes (2)

  • Annualized joint bleeding rate

    Annualized joint bleeding rate(AJBR) can be calculated using the following formula: Number of joint bleeding events during efficacy evaluation period/(number of days in treatment period/365.25).

    up to 24 weeks

  • Incremental Recovery of the First Dose

    Peak activity of FVIII (as Cmax) measured within 1 hour after the end of injection

    After the first dose on day 1

Secondary Outcomes (6)

  • Bleeding Event Treatment Efficacy

    up to 24 weeks

  • Monthly Average Number of Bleedings

    up to 24 weeks

  • The number and dose of injection of Recombinant Human Coagulation FVIII required per bleeding episode

    up to 24 weeks

  • Incremental Recovery of Duplicated Dose

    up to 12 weeks, 24 weeks

  • Hemophilia Joint Health Score (HJHS)

    Baseline, week 24

  • +1 more secondary outcomes
