Assess the Efficacy and Safety of Personalized Prophylaxis Human-cl rhFVIII in Patients With Severe Haemophilia A

2020年12月21日 更新者:Octapharma

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

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.
