Brief Summary
This trial is designed to assess if there is evidence of subclinical joint bleeding on MRI/X-Ray in adults with severe Haemophilia A while on standard and/or pharmacokinetically tailored prophylaxis regimens. Participants with severe Haemophilia A will have longitudinal MRI and XRay imaging of their elbows, ankles and knees at 0, 6 and 18 months while on standard ( 0-6 months) and then pharmacokinetically tailored (7-18 months) recombinant Factor VIII prophylaxis.

Study Arms (2)
Standard prophylaxis
ACTIVE COMPARATORAdvate \[Antihemophilic Factor(Recombinant)\] 20-40 IU/kg 5-7 infusions per 14days
Pharmacokinetic tailored prophylaxis
EXPERIMENTALAdvate \[Antihemophilic Factor(Recombinant)\] dose determined by individual patient pharmacokinetics and infusions administerd on alternate days
Interventions
In Arm 1 prior patients will be dosed as per body weight 20-40 IU/kg 5-7 infusions per fortnight
Eligibility Criteria
You may qualify if:
- Male patients with severe Haemophilia A (baseline Factor VIII level of \<0.01 IU/mL)
- Age 18 years and above
- Patients taking any regular prophylactic regimen (defined as regular factor VIII infusions, at least 5 times a fortnight, with the aim of minimising haemarthroses and other clinically significant bleeds).
- Low titre inhibitors, past history of an inhibitor, abnormal liver function, drugs that interfere with haemostasis and low Cluster of Differentiation 4 (CD4) counts are allowed.
You may not qualify if:
- Presence of a target joint on prophylaxis (defined as 3 bleeds into one joint, during a 6 month period, during the last year).
- The occurrence of more than 3 haemarthroses in the last year that required more than 2 infusions to resolve.
- Patients with a learning disability or dementia
- Prisoners
- Adults who are unconscious/unable to give informed consent
- Participants with a pacemaker or implanted medical devices which are unsuitable to have a MRI will be excluded from the MRI scans during the trial but may proceed with other components.
