Anticoagulation in Critically Ill Patients With COVID-19 (The IMPACT Trial)
- Conditions

- Registration Number
- NCT04406389
- Lead Sponsor
- Weill Medical College of Cornell University
- Brief Summary
The purpose of this study is to determine if therapeutic dose anticoagulation (experimental group) improves 30-day mortality in participants with COVID-19 compared to those patients receiving the intermediate dose prophylaxis (control group). Following screening, subjects will be randomized 1:1 to intermediate dose prophylaxis or therapeutic dose anticoagulation treatment arms.Treatment will continue for 28 days, followed by a 6 month follow-up period.

Group Intervention Description Intermediate Dose Prophylaxis Unfractionated heparin Subjects will receive one of the following interventions, at their physician's discretion: * Enoxaparin 0.5 mg/kg subcutaneously every 12 hours if creatinine clearance greater than or equal to 30 ml/min * Enoxaparin 0.5 mg/kg subcutaneously every 24 hours if creatinine clearance less than 30 mL/min * If patient develops acute kidney injury: unfractionated heparin 7,500 units subcutaneously every 8 hours. * Fondaparinux (if history of heparin-inducted thrombocytopenia \[HIT\]) 2.5 mg daily subcutaneously Intermediate Dose Prophylaxis Fondapariniux Subjects will receive one of the following interventions, at their physician's discretion: * Enoxaparin 0.5 mg/kg subcutaneously every 12 hours if creatinine clearance greater than or equal to 30 ml/min * Enoxaparin 0.5 mg/kg subcutaneously every 24 hours if creatinine clearance less than 30 mL/min * If patient develops acute kidney injury: unfractionated heparin 7,500 units subcutaneously every 8 hours. * Fondaparinux (if history of heparin-inducted thrombocytopenia \[HIT\]) 2.5 mg daily subcutaneously Therapeutic Dose Anticoagulation Fondapariniux Subjects will receive one of the following interventions, at their physician's discretion: * Unfractionated heparin (UFH) to target anti-Xa level 0.3 -0.7 IU/mL or activated partial thromboplastin time (aPTT) (according to institutional protocol). * Enoxaparin 1 mg/kg subcutaneously every 12 hours * Argatroban (if heparin-induced thrombocytopenia \[HIT\]), dosed according to institutional protocol. * Fondaparinux (if HIT and creatinine clearance greater than or equal to 50 ml/min) dosed by weight: * ≥100 kg: 10 mg daily * \<100 kg but ≥50 kg: 7.5 mg daily * \<50 kg: 5 mg daily Therapeutic Dose Anticoagulation Argatroban Subjects will receive one of the following interventions, at their physician's discretion: * Unfractionated heparin (UFH) to target anti-Xa level 0.3 -0.7 IU/mL or activated partial thromboplastin time (aPTT) (according to institutional protocol). * Enoxaparin 1 mg/kg subcutaneously every 12 hours * Argatroban (if heparin-induced thrombocytopenia \[HIT\]), dosed according to institutional protocol. * Fondaparinux (if HIT and creatinine clearance greater than or equal to 50 ml/min) dosed by weight: * ≥100 kg: 10 mg daily * \<100 kg but ≥50 kg: 7.5 mg daily * \<50 kg: 5 mg daily Intermediate Dose Prophylaxis Enoxaparin sodium Subjects will receive one of the following interventions, at their physician's discretion: * Enoxaparin 0.5 mg/kg subcutaneously every 12 hours if creatinine clearance greater than or equal to 30 ml/min * Enoxaparin 0.5 mg/kg subcutaneously every 24 hours if creatinine clearance less than 30 mL/min * If patient develops acute kidney injury: unfractionated heparin 7,500 units subcutaneously every 8 hours. * Fondaparinux (if history of heparin-inducted thrombocytopenia \[HIT\]) 2.5 mg daily subcutaneously Therapeutic Dose Anticoagulation Unfractionated heparin Subjects will receive one of the following interventions, at their physician's discretion: * Unfractionated heparin (UFH) to target anti-Xa level 0.3 -0.7 IU/mL or activated partial thromboplastin time (aPTT) (according to institutional protocol). * Enoxaparin 1 mg/kg subcutaneously every 12 hours * Argatroban (if heparin-induced thrombocytopenia \[HIT\]), dosed according to institutional protocol. * Fondaparinux (if HIT and creatinine clearance greater than or equal to 50 ml/min) dosed by weight: * ≥100 kg: 10 mg daily * \<100 kg but ≥50 kg: 7.5 mg daily * \<50 kg: 5 mg daily Therapeutic Dose Anticoagulation Enoxaparin sodium Subjects will receive one of the following interventions, at their physician's discretion: * Unfractionated heparin (UFH) to target anti-Xa level 0.3 -0.7 IU/mL or activated partial thromboplastin time (aPTT) (according to institutional protocol). * Enoxaparin 1 mg/kg subcutaneously every 12 hours * Argatroban (if heparin-induced thrombocytopenia \[HIT\]), dosed according to institutional protocol. * Fondaparinux (if HIT and creatinine clearance greater than or equal to 50 ml/min) dosed by weight: * ≥100 kg: 10 mg daily * \<100 kg but ≥50 kg: 7.5 mg daily * \<50 kg: 5 mg daily
