Reliable efficacy when you and your patients need it most^1,2

Prophylaxis

Prophylactic treatment in PTPs
	reduction in ABR vs on-demand In PTPs. ReFacto® prophylaxis is more effective at preventing bleeds than on-demand treatment, with an 85% reduction of bleeds per year (median ABR: 3.4; n=154) achieved with prophylactic treatment3

On-demand treatment

On-demand treatment in PTPs
	of 10,882 bleeding episodes were treated effectively with only 1 infusion (n=113)1,2
On-demand treatment in PUPs
	of 2,715 bleeding episodes were treated effectively with only 1 infusion (n=101)1,2
Surgery
	of infusions administered were rated as excellent or good by the surgeon and treating physician (38 patients; 48 surgical procedures; 496 infusions during or after surgery)1,*

ReFacto AF^® is manufactured using the same cell line as ReFacto⁴ and is pharmacokinetics-equivalent to ReFacto^®5, so it is expected to behave in the same way.

*Excellent rating: achievement of comparable haemostasis to that expected after similar surgery in a non-haemophilic patient. Good rating: prolonged time to haemostasis with somewhat increased bleeding compared with that expected after similar surgery in a non-haemophilic patient.¹

Safety

A favourable safety profile⁵

The most common adverse reactions reported in pooled clinical trials with 715 subjects (591 PTPs, 124 PUPs)⁵:

• Factor VIII inhibitors in PUPs, headache, cough, arthralgia and pyrexia – very common (≥10%)
• Factor VIII inhibitors in PTPs - uncommon (>0.1 to <1%). Decreased appetite, dizziness, haemorrhage, haematoma, diarrhoea, vomiting, abdominal pain, nausea, urticaria, rash, pruritus, myalgia, chills, catheter-site-related reaction, antibody test positive and anti-factor VIII antibody test positive – common (≥1% to <10%)

Inhibitor formation

PTPs^1,3,6–8

Switching from recombinant or plasma-derived factor to ReFacto AF® did not significantly increase the risk of inhibitor formation.^3,8
