Hamburg Edoxaban for Anticoagulation in COVID-19 Study

Coagulopathy in the context of COVID-19 is a major threat to affected patients due to deep vein thromboses and pulmonary embolisms. Actual data show an unexpectedly high incidence of partially fatal complications without any prior clinical evidence in some cases. Therefore, this prospective, randomized, assessor-blinded, multicenter, placebo-controlled, interventional trial will investigate whether therapeutic anticoagulation on top of SOC compared to prophylactic anticoagulation as part of SOC- can improve objective patient-relative endpoints, relevant for prognosis in patients with COVID-19. 172 eligible patients will be randomized 1:1 to experimental or control group. Patients enrolled to experimental group will receive therapeutic anticoagulation using LMWH body weight-adapted during course of hospital stay and oral anticoagulation using Edoxaban according to SmPC (60mg once a day) after being discharged from hospital / outpatient course. Patients enrolled to control group will receive prophylactic anticoagulation using LMWH as part of SOC whilst inpatient course, and placebo after discharge / outpatient course. Patients will be informed of their allocation to the placebo group, as it has been shown that the effect of placebo is still detectable.
