wilate® is a high-purity plasma-derived von Willebrand factor and coagulation factor VIII (VWF/FVIII) concentrate

wilate® was developed specifically for people with von Willebrand disease (VWD), and contains VWF and FVIII in a physiological 1:1 activity ratio, which may facilitate simple dosing and monitoring even when repeated dosing is needed.4, 5

The purification process includes two virus inactivation steps in order to ensure a high-purity product free of viral contamination.4

Over 15 years of clinical and real-life experience have proven the efficacy and tolerability of wilate® in people with all types of von Willebrand disease for surgery, on-demand treatment and prophylaxis.1-3

wilate® is a high-purity plasma-derived von Willebrand factor and coagulation factor VIII (VWF/FVIII) concentrate

*Based on von Willebrand factor and factor VIII activity levels. FVIII, coagulation factor VIII; VWF, von Willebrand factor.

In the European Union, wilate® is indicated for the prevention and treatment of haemorrhage or surgical bleeding in von Willebrand disease, when desmopressin treatment alone is ineffective or contra-indicated 6

Physiological 1:1 ratio of VWF and FVIII in wilate®

One of the functions of VWF is to bind to and protect FVIII from proteolytic degradation.4


As a result, people with von Willebrand disease may have low levels of both VWF and FVIII, both of which need to be corrected in order to restore normal haemostasis.4

wilate® contains VWF and FVIII in a balanced 1:1 ratio*, which is similar to the activity ratio of VWF and FVIII in the plasma of healthy individuals4

*Based on von Willebrand factor and factor VIII activity levels.

Manufacturing of wilate®

wilate® is a high-purity, human VWF/FVIII concentrate

1_6@2x

wilate® is made from pooled human plasma that has been collected in GMP-compliant donation centres, which are regularly inspected by Octapharma and national and international authorities9

FVIII, factor VIII; GMP, good manufacturing practice; VWF, von Willebrand factor.

wilate® is a high-purity, human VWF/FVIII concentrate

All individual plasma samples undergo extensive testing for viruses, including for HIV, hepatitis A, B and C and parvovirus B199, 10

FVIII, factor VIII; HIV, human immunodeficiency virus; VWF, von Willebrand factor.

Manufacturing of wilate®

wilate® is a high-purity, human VWF/FVIII concentrate

wilate® is purified through a series of carefully controlled processing steps, all designed to minimise impurities and ensure viral safety4


Two chromatographic steps ensure high purity and remove non-essential proteins4

Viral safety is achieved by two complementary virus inactivation steps4

Manufacturing of wilate®

Double virus inactivation process

HBV, hepatitis B virus; HCV, hepatitis C virus; HIV, human immunodeficiency virus.
