|Condition or disease||Intervention/treatment||Phase|

Coronavirus disease-2019 (COVID-19) -- a viral illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) -- has important manifestations outside the pulmonary parenchyma, including microthrombosis and macrothrombosis, with venous thrombosis being the most common form of thrombotic involvement. Existing studies, depending on the type of outcome assessment and type and dose of prophylaxis, have reported thrombotic events in 7-85% of patients with COVID-19.
However, the optimal antithrombotic regimen in these patients remains uncertain. Although many clinicians continue to consider standard-dose prophylactic anticoagulation, other believe that more intense anticoagulation may reduce the thrombotic events, and improve outcomes. However, limited high-quality data exist to inform clinical practice and the existing guidelines recommendations are mostly based on expert opinion and consensus.
In addition, exuberant inflammatory response is known to play a role in the pathophysiology of acute respiratory distress syndrome (ARDS) and COVID-19. It is possible that the pleiotropic effects of statins, which include anti-inflammatory and antithrombotic effects, prove beneficial in patients with severe COVID-19.
This study plans to investigate the safety and efficacy of two pharmacological regimens on outcomes of critically-ill patients with COVID-19 using a 2x2 factorial design.
First, patients will be assessed for the eligibility criteria for the anticoagulation hypothesis. Those meeting the criteria, will be assigned to intermediate versus standard dose prophylactic anticoagulation. These patients will subsequently be assessed for eligibility for the second randomization, and if meeting the criteria, will be assigned to atorvastatin 20mg/d or matching placebo.

Experimental: Intermediate dose anticoagulation
Intermediate dose anticoagulation will be the the tested regimen. The anticoagulation regimen will be modified according to weight/ body mass index, and creatinine clearance level (Cl Cr). Enoxaparin will be the primary agent for anticoagulation, with unfractionated heparin reserved only for patients with creatinine clearance of ≤15 mL/min according to Cockcroft-Gault Formula.
Drug: intermediate dose Enoxaparin/ unfractionated heparin
Intermediate dose anticoagulation according to creatinine clearance and weight
Other Name: Intermediate dose anticoagulation
Active Comparator: Standard Prophylaxis
Standard prophylaxis dose anticoagulation will be the anticoagulation of choice in the control arm. Enoxaparin will be the primary agent for anticoagulation, with unfractionated heparin reserved only for patients with creatinine clearance of ≤15 mL/min according Cockcroft-Gault Formula.
Drug: standard prophylactic dose Enoxaparin/ unfractionated heparin
Standard prophylaxis anticoagulation according to creatinine clearance and weight
Other Name: Standard dose prophylaxis anticoagulation
Experimental: Atorvastatin 20
Atorvastatin 20 mg daily will be the statin therapy of choice in the intervention arm
Drug: Atorvastatin 20mg
Other Name: Statin
Placebo Comparator: Atorvastatin 20 mg Matched placebo
Matching placebo will be used for the control arm
Drug: Matched placebo
Matched placebo to atorvastatin 20 mg
Other Name: Statin
