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.
