Summary

Patients with severe Haemophilia A need prophylactic factor VIII to reduce their risk of joint and soft tissue bleeds and to prevent or reduce joint damage. It is common practice to give enough factor VIII to maintain the trough level above 1% of normal and this has been supported in retrospective studies.

The amount of factor VIII required to maintain this trough level varies markedly between patients because their factor VIII half lives are different. This study will assess the role of regular pharmacokinetic (PK)monitoring and dose adjusted factor VIII to establish whether this is a more cost effective way of giving treatment and whether it is feasible in routine clinical practice. Patients will be treated for 6 months with their standard factor VIII regimen and followed up to establish their bleed frequency. They will then receive pharmacokinetic adjusted factor VIII to maintain a trough above 1.5% for a year and their bleed rate compared to standard treatment. If they have increased break through bleeds their factor VIII will be increased to maintain a trough of 3%.

Conditions

  • Severe Haemophilia A

Interventions

DRUG

Pharmacokinetic based dosage change

Pharmacokinetic based dosing of factor VIII prophylaxis treatment compared to standard prophylactic regimens based on weight.Prophylaxis is prescribed according to routine clinical practice with prophylaxis prescribed on alternate days to maintain predicted target trough of ≥1.5 IU/dL based on sparse blood sampling and Bayesian pharmacokinetic estimation
