​​​​​​ReFacto AF® (moroctocog alfa) is indicated for the treatment and prophylaxis of bleeding in patients with haemophilia A (congenital factor VIII deficiency). ReFacto AF® is appropriate for use in adults and children of all ages, including newborns. ReFacto AF® does not contain von Willebrand factor, and hence is not indicated in von Willebrand's disease.1

Patient satisfaction with the FuseNGo

The FuseNGo device is a pre-filled syringe that allows all-in-one reconstitution and administration of ReFacto AF®. Studies show that patients are satisfied with administration of factor VIII with the FuseNGo.2,3​​​​​​​

Patient reported outcomes

The FuseNGo was developed for ease of administration, containing separate chambers for the powder and solution (uniformly 4 mL).1–3

​​​​​​​Patients preferred the ReFacto AF® FuseNGo reconstitution vs. other routine devices tested:2†,3‡

Satisfied with administration

Preferred device

Product most likely to be used prophylactically

Achieved high adherence scores

In one study, when patients considered their experience with the ReFacto AF® FuseNGo device, significant increases in the proportion of positive responses were seen for all four questions regarding ease of use compared with the current treatment.2​​​​​​​

Adapted from Di Minno G et al. Patient Preference and Adherence 2019:13 233–240.2

Easy to use

More patients found ease of preparation, storage, disposal of needles and syringes, and use of treatment to be convenient with the ReFacto AF® FuseNGo device compared with their current treatment.2  

​​​​​​​Similar results were found in the survey of ease of reconstitution of factor VIII product, where ReFacto AF® FuseNGo device scored the same or higher than other devices for:3  

  • ​​​​​​​Ease of preparing clotting factor  
  • Ease of handling the device  
  • Ease of disposal of syringes and needles  
  • Ease of pushing down the syringe plunger

The improvements from current treatment were significant (P<0.01 Wilcoxon signed ranks test) for all questions.

Adapted from Di Minno G et al. Patient Preference and Adherence 2019:13 233–240.2



At baseline, the mean time to reconstitution of factor VIII product was 11 minutes. At follow-up, the reconstitution time was reduced to 6 minutes when patients were using the ReFacto AF® FuseNGo device.2  

Rapid reconstitution and administration

Positive responses to questions about effectiveness, convenience and overall satisfaction of the ReFacto AF® FuseNGo device approached or exceeded 90% in all cases.2 

98.8% of patients responded positively to both questions about overall satisfaction with the treatment delivery system.2

High levels of patient satisfaction

Patients receiving prophylactic factor VIII self-reported a treatment adherence >70% with ReFacto AF® FuseNGo.

High levels of treatment adherence  

†  An Italian study administered five questionnaires to patients with haemophilia A (from 21 centres; N=84 completed the study), including the specifically developed HemoPREF questionnaire for patient-related outcomes. Questionnaires were administered at baseline (when patients were using their current treatment) and at a final visit 3–6 months after the baseline visit, and after patients had experience of the ReFacto® FuseNGo delivery device.2  

‡  A cross-sectional survey conducted across 5 European countries (N=299) compared the ReFacto® FuseNGo device with four other methods of reconstituting factor VIII product.3 This survey looked at reconstitution and did not involve administration of the product. 

§  Patients who reported “always” or “often” adhering to treatment.
