Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this study is to determine the efficacy of Wilate in the prophylactic treatment of previously treated patients (PTP) with severe hemophilia A. ;Secondary Objective: The secondary objectives of this study are to: • Determine the efficacy of Wilate in the treatment of breakthrough bleeding episodes (BEs) • Determine the efficacy of Wilate in surgical prophylaxis • Calculate the FVIII:C pharmacokinetics (PK) for Wilate at baseline • Calculate the FVIII:C incremental IVR of Wilate over time (at baseline, and at 3 and 6 months of treatment) • Assess the association between AB0 blood type and the FVIII:C half-life of Wilate • Assess the association between the VWF:Ag concentration and the FVIII:C half-life of Wilate • Assess the safety and tolerability of Wilate • Assess the immunogenicity of Wilate ;Primary end point(s): The primary endpoint of this study is a 50% reduction of the total annualized bleeding rate (TABR) observed in the GENA-01 study, with a total of 58.1 BEs per patient per year.;Timepoint(s) of evaluation of this end point: After the end of the study | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary endpoints of this study are the: 1. Spontaneous annualized bleeding rate (SABR) 2. Efficacy of Wilate in the treatment of breakthrough BEs based on the proportion of BEs successfully treated with Wilate 3. Descriptive efficacy of Wilate in surgical prophylaxis 4. Wilate consumption data (FVIII IU/kg per week per patient) for prophylaxis ;Timepoint(s) of evaluation of this end point: After the end of the study | — |
