Clinical Trial Summary

Studies have shown, in haemophilia patients, the effectiveness of Anti TFPI antibody (aTFPIAb) to prevent joint and muscular bleeding (tissues poor in Tissue Factor (TF)). However, cases of cerebral thrombosis (tissues rich in TF) have been observed in some patients treated with this antibody. Because an inter-individual variation in thrombin generation correction by aTFPIAb, an aTFPIAb concentration effective at low TF concentration could be at the same time thrombogenic at high TF concentration.


Clinical Trial Description

The aim of this study is to determine, for each patient, the minimum concentration of aTFPIAb necessary to restore thrombin generation in the presence of low (1pM) TF concentration and to evaluate at this concentration of aTFPIAb a potential thrombogenic effect in the presence of a high (10pM) TF concentration. ;
