Brief Summary:
This is a multicenter, open-label, 2x2 factorial, randomized-controlled trial in critically-ill patients with novel coronavirus disease 2019 (COVID-19) evaluating the efficacy and safety of full-dose vs. standard prophylactic dose anticoagulation and of antiplatelet vs. no antiplatelet therapy for prevention of venous and arterial thrombotic events.

Condition or disease Intervention/treatment Phase
COVID-19 Venous Thromboembolism Arterial Thrombosis Drug: Unfractionated Heparin IV Drug: Enoxaparin 1 mg/kg Drug: Clopidogrel Drug: Unfractionated heparin SC Drug: Enoxaparin 40 Mg/0.4 mL Injectable Solution Phase 4
