Methods |
Multicentre, open‐label, 2‐armed, parallel‐assignment RCT |
Participants |
170 participants, ≥ 18 years, female and male Inclusion criteria
Laboratory‐confirmed SARS‐CoV‐2 infection
Age: ≥ 18 years
Requires hospital admission for further clinical management
Modified ISTH overt DIC score ≥ 3
Exclusion criteria
Indication for full therapeutic‐dose anticoagulation
Acute VTE (DVT or PE) within prior 3 months
Acute cardiovascular event within prior 3 months
Acute stroke (ischaemic or haemorrhagic) within prior 3 months
Active major bleeding
Severe thrombocytopenia (< 25,000/mm3)
Increased risk of bleeding, as assessed by the investigator
Acute or chronic renal insufficiency with creatinine clearance < 30 mL/min calculated by the modified Cockcroft and Gault formula
Weight < 40 kg
Known allergies to ingredients contained in enoxaparin, allergy to heparin products or history of HIT
|
Interventions |
Interventional: intermediate‐dose enoxaparin (1 mg/kg SC daily if BMI < 30 kg/m2 or 0.5 mg/kg SC twice daily if BMI ≥ 30 kg/m2) Comparator: standard of care. Standard prophylactic dose enoxaparin (40 mg SC daily if BMI < 30 kg/m2 and 30 mg SC twice daily or 40 mg SC twice daily if BMI ≥ 30 kg/m2) |
Outcomes |
Primary
Secondary
Risk of ISTH‐defined major bleeding (time frame: 30 days post‐intervention)
Arterial thrombosis (time frame: 30 days post‐intervention). Risk of ischaemic stroke, myocardial infarction and/or limb ischaemia
VTE (time frame: 30 days post‐intervention). Risk of symptomatic VTE
ICU admission, intubation/ventilation (time frame: 30 days post‐intervention). Duration of intensive care measures
PRBC transfusions (time frame: 30 days post‐intervention). The number of units of PRBCs transfused
Platelet transfusions (time frame: 30 days post‐intervention). The number of units of platelets transfused
Fresh frozen plasma transfusions (time frame: 30 days post‐intervention). The number of units of fresh frozen plasma transfused
Cryoprecipitate transfusions (time frame: 30 days post‐intervention). The number of units of cryoprecipitate transfused
Prothrombin complex concentrate transfusions (time frame: 30 days post‐intervention). The number of units of prothrombin complex concentrate transfused
Other outcomes
The endogenous thrombin potential will be determined within 24 h of randomisation and weekly for 30 days or until hospital discharge (time frame: 30 days post‐intervention). Will be performed in stored plasma using calibrated automated thrombogram. The endogenous thrombin potential will be calculated in units of nM.Min
Plasma levels of cell‐free DNA will be determined within 24 h of randomisation and weekly for 30 days or until hospital discharge (time frame: 30 days post‐intervention). These assays will be performed in stored plasma. Quantification of cfDNA will be performed using Qubit dsDNA HS Assay kit. Histones H4, citrullinated‐histone and DNA‐myeloperoxidase will be measured using commercially available ELISA kit.
PAI‐1 (time frame: 30 days post‐intervention) will be measured in stored plasma using a commercially available ELISA kit.
