About this trial

Assessment of high-normal dosage of Wilate ® compared to placebo administered in combination with platelets to assess reduction of amount of blood loss, need of transfusion products and outcome (length of stay, mortality) in patients with bleeding in comparison.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 18 years

Admission to intensive care unit

Patients needing platelet transfusion during or after surgery with or without prior treatment with single or dual antiplatelet agents (ASS, Prasugrel, Clopidogrel, Ticagrelor)

Consent by the patient or a family member in addition to the consent of an independent ICU physician

Disqualifiers

Patients receiving Factor VIII concentrate before inclusion of the study (Haemate ®)

Women who are pregnant or breastfeeding

Participation in another study with an investigational drug within the 30 days preceding and during the present study

Overt Disseminated Intravascular Coagulation (DIC)

Trial design

Design model

Parallel

Treatments tested in this trial

  • Wilate

    Drug

    Wilate ® will be given with platelets in cases of severe bleeding. Wilate ® is a 1:1 balanced mixture of von Willebrand Factor (2'000 IU) and Coagulation factor VIII (2'000 IU) and as such has anti-haemorrhagic potential. It is extracted from plasma, freeze-dried and virus-inactivated.

  • Placebo

    Other intervention

    Empty placebo will be given with platelets in cases of severe bleeding.

Treatment groups

120 Participants
are divided into 2 treatment groups
Group A: Platelet transfusion with Wilate ®Experimental treatment 1 intervention
Group B: Platelet transfusion with PlaceboPlacebo comparator 1 intervention
