What researchers measure

Primary outcomes

  1. 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).

    Time frame: up to 24 weeks

  2. Incremental Recovery of the First Dose

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

    Time frame: After the first dose on day 1

Secondary outcomes

  1. Bleeding Event Treatment Efficacy

    The investigator shall evaluate the hemostatic effect after the treatment of every bleeding event of subjects based on a four-point scale(excellent, good, moderate, not relieved).

    Time frame: up to 24 weeks

  2. Monthly Average Number of Bleedings

    Number of bleeding events in each month.

    Time frame: up to 24 weeks

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

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

    Time frame: up to 24 weeks

  4. Incremental Recovery of Duplicated Dose

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

    Time frame: up to 12 weeks, 24 weeks

  5. Hemophilia Joint Health Score (HJHS)

    The scale assesses the functional status of the six major joints of the elbow, knee, and ankle, including: joint swelling, swelling duration, muscle atrophy, muscle strength, joint friction, joint pain, joint extension, joint flexion Degree decline, overall gait, etc.

    Time frame: Baseline, week 24

  6. Assess the impact of Recombinant Human Coagulation FVIII following Patient Reported Outcome (PRO) EQ-5D

    EQ-5D is a general questionnaire designed to measure health status on a scale of 0-100 with the higher value representing a better outcome and record the participants' current health state in 5 domains mobility, selfcare, usual activities, pain, anxiety.

    Time frame: Baseline, week 24
