Plain English summary of protocol

Background and study aims
Patients with von Willebrand disease (a bleeding disorder that affects your blood's ability to clot) may require substitution with a coagulation factor concentrate like Wilate. In this study, data about the treatment with Wilate will be collected for safety surveillance and efficacy evaluations.

Who can participate?
All patients with von Willebrands disease in need for replacement therapy who’s doctor had first decided to use Wilate and then to participate in the study can be included.

What does the study involve?
The treatment with Wilate will be the same as prescribed by the doctor without the study – no additional interventions are required. Careful documentation of therapy by the doctor or in case of home treatment by the patient is necessary.

What are the possible benefits and risks of participating?
All information collected in the course of the treatment with Wilate will add knowledge on the use of Wilate and treatment of the von Willebrand disease under routine conditions. There are no risks arising from participation.

Where is the study run from?
The study will take place in several haemophilia centres in Germany.

When is the study starting and how long is it expected to run for?
June 2012 to May 2020

Who is funding the study?

Scientific titleSurveillance of Tolerability And Treatment Efficacy of Wilate® in von Willebrand’s disease: an observational study
Study acronymWilate-STATE
Study objectivesWilate 500/1000 is safe and efficacious for treatment of von Willebrand's disease in clinical practice.
Ethics approval(s)Ethics Committee of Medical Faculty of Johann Wolfgang Goethe University Frankfurt/Main Germany, November 2012
Health condition(s) or problem(s) studiedvon Willebrand's disease
InterventionFor this non-interventional study, details of the patient history and the current treatment with Wilate will carefully be recorded. This included information on of injections, duration and intensity of bleeding episodes and information regarding possible surgical interventions. The efficacy will be assessed according to a 4-point verbal rating scale. Suspected adverse drug reactions (”side effects”) will be documented. The observation time depends on the clinical needs of the patient, e.g. from a few days in case Wilate is required only to cover a surgery or until study end in case of prophylactic treatment.
