Brief summary
CREHA project is a study comparing steroid combined with cyclophosphamide versus steroid combined with rituximab in patients with acquired haemophilia. The study will test the hypothesis that steroid combined with cyclophosphamide is more effective than steroid plus rituximab for FVIII inhibitor eradication in acquired haemophilia.
Detailed description
CREHA project is a multicenter, randomized, controlled efficacity and safety study comparing steroid combined with cyclophosphamide versus steroid combined with rituximab in patients with acquired haemophilia. The study will test the hypothesis that steroid combined with cyclophosphamide is more effective than steroid plus rituximab for FVIII inhibitor eradication in acquired haemophilia

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Primary objective | During 18 months | Demonstrate the inferiority of steroid combined with rituximab as compared to the recommended immunosuppressive approach (steroid combined with cysclophosphamide for 21 to 42 days) as the first-line immunosuppressive therapy for FVIII inhibitor eradication in acquired haemophilia |
| Primary efficacy outcome | During 18 months | The primary efficacy outcome is the proportion of patients achieving complete remission defined as titer FVII inhibitor lower than 0.4 Bethesda unit and factor VIII level \> 50% |
| Primary safety outcomes | During 18 months | The primary safety outcomes will be the occurrence of major bleeding and infection related immunosuppressive treatment adverse events. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Secondary objective | 6 months, 12 months and 18 months | Secondary objective are time to complete remission, number of relapse at M6, M12, M18, adverse events (especially related to bleeding or to immunosuppressive treatment) and mortality |
| Other key safety outcome | During 18 months | The other key safety outcome are clinically relevant non major bleeding, diabetes and mortality non-related with acquired haemophilia or immunosuppressive therapy |
