Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: November 13, 2019)
  • Annualized Spontaneous Bleeding Rate of Individually Tailored Prophylaxis [ Time Frame: 6 months ]
    Spontaneous annualized bleeding rate (ABR) of individually tailored prophylaxis (GENA-21b) compared to historical bleeding rate in patients having received on-demand treatment (GENA-01) with Human-cl rhFVIII
  • Annualized Total Bleeding Rate in Patients With 2x/Week (or Less) Prophylaxis [ Time Frame: 6 months ]
    Total annualized bleeding rate (ABR) in patients with 2x/week (or less) prophylaxis (GENA-21b) compared to historical bleeding rate in patients having received on-demand treatment (GENA-01) with Human-cl rhFVIII
  • Median Prophylactic Dosing Interval [ Time Frame: 6 months ]
    Median over median actual dosing intervals between two prophylactic treatments per patient. The median time (hours) between two prophylactic doses of Human-cl rhFVIII in the prophylactic treatment Phase II per patient
  • Mean Prophylactic Dosing Interval [ Time Frame: 6 months ]
    Mean over mean actual dosing intervals between two prophylactic treatments per patient. The mean time (hours) between two prophylactic doses of Human-cl rhFVIII in the prophylactic treatment Phase II per patient
  • AUC Divided by the Dose (AUCnorm) of Human-cl rhFVIII [ Time Frame: Before injection (within 1 h before injection) and up to 72 h (± 2 h) after the end of injection ]
    AUCnorm of Human-cl rhFVIII measured using the one-stage (OS) assay
  • In-vivo Recovery (IVR) of Human-cl rhFVIII [ Time Frame: Before injection (within 1 h before injection) and up to 72 h (± 2 h) after the end of injection ]
    IVR of Human-cl rhFVIII measured using the one-stage (OS) assay and will be determined from the FVIII level before the infusion and the peak level after the infusion of Human-cl rhFVIII
  • Half Life (t1/2) of Human-cl rhFVIII [ Time Frame: Before injection (within 1 h before injection) and up to 72 h (± 2 h) after the end of injection ]
    T1/2 of Human-cl rhFVIII measured using the one-stage (OS) assay
  • Mean Residence Time (MRT) of Human-cl rhFVIII [ Time Frame: Before injection (within 1 h before injection) and up to 72 h (± 2 h) after the end of injection ]
    MRT of Human-cl rhFVIII measured using the one-stage (OS) assay
  • Clearance (CL) of Human-cl rhFVIII [ Time Frame: Before injection (within 1 h before injection) and up to 72 h (± 2 h) after the end of injection ]
    CL of Human-cl rhFVIII measured using the one-stage (OS) assay
  • Volume of Distribution at Steady State (Vss) of Human-cl rhFVIII [ Time Frame: Before injection (within 1 h before injection) and up to 72 h (± 2 h) after the end of injection ]
    Vss of Human-cl rhFVIII measured using the one-stage (OS) assay
  • Usage of Human-cl rhFVIII (FVIII IU/kg BW Per Week Per Patient) [ Time Frame: 6 months ]
    Average weekly consumption of Human-cl rhFVIII reported as IU/kg BW per week per patient was determined during individualized prophylactic treatment
  • Number of Patients With Adverse Events (AEs) [ Time Frame: At each study visit over the study duration (7-9 months) ]
    AEs were documented at each (scheduled or unscheduled) study visit. Severity and seriousness of all AEs were documented by the investigator according to pre-defined criteria
Original Secondary Outcome Measures  ICMJE
 (submitted: October 1, 2014)
  • Annualized spontaneous bleeding rate of individually tailored prophylaxis [ Time Frame: 2.5 years ]
    Annualized spontaneous bleeding rate of individually tailored prophylaxis compared to historical bleeding rate in patients having received on-demand treatment with Human-cl rhFVIII
  • Annualized total bleeding rate in patients with 2x/week (or less) prophylaxis [ Time Frame: 2.5 years ]
    Annualized total bleeding rate in patients with 2x/week (or less) prophylaxis compared to historical bleeding rate in patients having received on-demand treatment with Human-cl rhFVIII
  • Median prophylactic dosing interval [ Time Frame: 2.5 years ]
  • Usage of Human-cl rhFVIII (FVIII IU/kg bw per month per patient) [ Time Frame: 2.5 years ]
  • Number of patients with Adverse events [ Time Frame: 2.5 years ]

Descriptive Information
Brief Title  ICMJE Assess the Efficacy and Safety of Personalized Prophylaxis Human-cl rhFVIII in Patients With Severe Haemophilia A
Official Title  ICMJE Prospective, Open-label, Multi-centre Phase 3b Study to Assess the Efficacy and Safety of Personalized Prophylaxis With Human-cl rhFVIII in Previously Treated Adult Patients With Severe Haemophilia A
Brief Summary The rationale of this study is to further fine-tune and individualize prophylactic treatment of patients with severe Haemophilia A with the goal of keeping the trough FVIII level above 1% between doses. Because trough FVIII levels are likely to be important predictors of the efficacy of prophylaxis, the focus of this study is on pharmacokinetic (PK) data.
