ACTIV4: Inpatient COVID-19 Study | Clinical Trials at Duke

The chance of blood clots in patients who are diagnosed with COVID-19 is higher than for patients who do not have COVID-19. Clots in the arteries, veins, and heart can cause heart attacks, strokes, and blockages.

Doctors are already giving most patients in the hospital for COVID-19 blood thinners at different doses. We are doing this study to compare a lower dose to a higher dose blood thinner to speed recovery and prevent blood clots in patients who are in the hospital for COVID-19.

The probability of developing clots is higher in patients with COVID-19 than in those patients who do not have COVID-19. Clots in the arteries, veins, and heart can cause heart attacks, strokes, and blockages.

We are doing this study to compare a lower dose and a higher dose of anticoagulant to speed recovery and prevent clots in patients hospitalized for COVID-19.
