Haemophilia A is caused by factor VIII deficiency and occurs in 1 in 5,000 to 1 in 10,000 male live births. Between 50% and 70% of people with haemophilia A have severe disease (<1% factor VIII activity). There were 5,424 patients with haemophilia A in the UK in 2011 (prevalence 8.7 per 100,000 population), 1,057 were aged 0-13 years.

Trial or other data
Dec 15ADYNOVATE meets endpoints in PIII trial (n=73) of Haemophilia A in pts under 12 yrs of age. The prospective, uncontrolled, open-label, multi-centre PIII study was designed to assess the safety and immunogenicity of ADYNOVATE. Previously-treated patients aged <12 with severe haemophilia A received prophylactic ADYNOVATE treatment (median 1.9 infusions per week) and were followed for six months. The treatment´s haemostatic efficacy in prophylaxis and treatment of bleeding was assessed. ADYNOVATE met its primary endpoint as no pts developed inhibitory antibodies to ADYNOVATE. No treatment-related serious adverse events were reported. 72.7 % of pts had no joint bleeds and 37.9% experienced no bleeds. The median annualized bleeding rate (ABR) among pts treated with ADYNOVATE was 2.0 (range 0-49.8; mean ABR 3.0), which was comparable to rates seen in the adult study .
Jul 15Results of BAX 855 trials published in blood journal .
Jul 15Baxalta announces positive data. Patients in the twice-weekly arm of the trial demonstrated a 95% reduction in median annualised bleed rate compared with the on-demand arm (1.9 vs. 41.5, respectively). BAX 855 was also effective in treating all bleeding episodes, 95.9% of which were controlled with one or two infusions at a median dose of 29.0 IU/kg per infusion .
Aug 14In top-line results from a global 6 month PIII study (n=138) BAX 855 met its primary endpoint in the control and prevention of bleeding, routine prophylaxis and perioperative management for patients ≥ 12 years. Patients on twice-weekly prophylaxis arm had a 95% reduction in median annualized bleed rates (ABR) vs those in the on-demand arm (1.9 vs. 41.5, respectively). BAX 855 was also effective in treating bleeding episodes, 96% of which were controlled with one or two infusions. The half-life of BAX 855 was 1.4 - 1.5 times that of ADVATE. No patients developed inhibitors to BAX 855 and no treatment-related serious AEs, including hypersensitivity, were reported .
Nov 13NCT01736475 (PROLONG-ATE) is a PII/III, multi-center, open label study of efficacy, safety, and pharmacokinetics of PEGylated recombinant Factor VIII (BAX 855) administered for prophylaxis and treatment of bleeding in 146 previously treated patients (aged 12-65 years) with severe Haemophilia A. Patients will receive treatment twice weekly (45 IU/kg) and followed for 6 months. The primary outcome is annualized bleeding rate. The study started Jun 13 and is due to complete Sep 14. Baxter is also initiating a continuation study (NCT01945593) .
Nov 13NCT01913405 is a PIII, multi-centre, open label study of efficacy and safety of PEGylated rFVIII (BAX 855) in 30 previously treated patients with severe Haemophilia A undergoing surgical or other invasive procedures. The primary outcome is Global Hemostatic Efficacy Assessment score (GHEA). the pre-operative loading dose and any intra-operative and post-operative dosing will be based on individual PK results as well as target trough level for type of surgery. The study started Sep 13 and is due to complete Dec 16
