Brief Summary

The coronavirus disease 2019 (COVID-19) global pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused considerable morbidity and mortality in over 170 countries. Increasing age and burden of cardiovascular comorbidities are associated with a worse prognosis among patients with COVID-19. In addition, serologic markers of more severe disease including coagulation abnormalities and thrombocytopenia, are not uncommon among patients hospitalized with severe COVID-19 infection and are more common in patients who died in-hospital. As the COVID-19 pandemic continues to grow, there is a pressing need to identify safe, effective, and widely available therapies that can be scaled and rapidly incorporated into clinical practice. Understanding the putative mechanism of increased mortality risk associated with abnormal coagulation function and cardiac injury is critical to guide studies of promising therapeutic interventions. Published and anecdotal reports indicate that endothelial dysfunction and thrombosis are common in critically ill patients with COVID-19, including reports of diffuse microvascular thrombosis in the lungs, heart, liver, and kidneys. Patients with cardiovascular disease (CVD) and CVD risk factors are known to have endothelial dysfunction and a heightened risk of thrombosis. A recent study of COVID-19 inpatients from Wuhan, China observed that an elevated D-dimer level greater than 1 ug/mL was associated with an 18 times higher risk of in-hospital death, underscoring the importance of increased coagulation activity as a potential modifiable risk marker that may drive end-organ injury. Given the established link between endothelial dysfunction and thrombosis in patients with cardiovascular disease, and the association between coagulopathy and adverse outcomes in patients with sepsis, the association between increased coagulation activity, end-organ injury, and mortality risk may represent a modifiable risk factor among COVID-19 patients with critical illness. Therefore, we propose to conduct a randomized, open-label trial of therapeutic anticoagulation in COVID-19 patients with an elevated D-dimer to evaluate the efficacy and safety.

Study Arms (2)

Therapeutic Anticoagulation Group

EXPERIMENTAL

Patients identified as eligible through discussions with the primary care team and review of the electronic medical record will be approached and consented as described above in "Subject Enrollment" and "Procedures for obtaining consent". For research purposes, 20ml of blood will be drawn and stored for biobanking at the following timepoints: at baseline (i.e., after enrollment and before randomization), 5-7 days post-randomization, and on the day of discharge. The blood sample taken at baseline will also be used to conduct a pregnancy test for women of childbearing age. After enrollment and blood collection, patients will then be randomized to therapeutic anticoagulation (LMWH for most subjects but UFH for those with morbid obesity or moderate to severe renal dysfunction as noted below) or standard of care anticoagulation. Those assigned to the therapeutic anticoagulation group will receive a higher dose of heparin.

Drug: Enoxaparin

Standard of Care Anticoagulation Group

ACTIVE COMPARATOR

Patients identified as eligible through discussions with the primary care team and review of the electronic medical record will be approached and consented as described above in "Subject Enrollment" and "Procedures for obtaining consent". For research purposes, 20ml of blood will be drawn and stored for biobanking at the following timepoints: at baseline (i.e., after enrollment and before randomization), 5-7 days post-randomization, and on the day of discharge. The blood sample taken at baseline will also be used to conduct a pregnancy test for women of childbearing age. After enrollment and blood collection, patients will then be randomized to therapeutic anticoagulation or standard of care anticoagulation. Those assigned to the standard of care anticoagulation group will receive the normal dose of heparin as per the Mass General guidelines.

Given the established link between endothelial dysfunction and thrombosis in patients with cardiovascular disease9, 10 and the association between coagulopathy and adverse outcomes in patients with sepsis11, the association between increased coagulation activity, end-organ injury, and mortality risk may represent a modifiable risk factor among COVID-19 patients with critical illness. Therefore, we propose to conduct a randomized, open-label trial of therapeutic anticoagulation in COVID-19 patients with an elevated D-dimer to evaluate the efficacy. Most patients will receive low molecular weight heparin however, unfractionated heparin (UFH) will be administered for those with morbid obesity or moderate to severe renal dysfunction.

Also known as: Heparin, Low molecular weight heparin
