Brief Summary

A multi-center adaptive randomized placebo-controlled platform trial evaluating the efficacy and safety of anti-thrombotic strategies in COVID-19 adults not requiring hospitalization at time of diagnosis

Detailed Description

The COVID-19 Outpatient Thrombosis Prevention Trial is a multi-center adaptive randomized double-blind placebo-controlled platform trial to compare the effectiveness of anti-coagulation with anti-platelet agents and with placebo to prevent thrombotic events in patients diagnosed with COVID-19 who have evidence of increased inflammation based on elevated D-dimer and hsCRP levels, yet are not admitted to hospital as COVID-19 related symptoms are currently stable. Participants will all be adults between 40 and 79 years who will be enrolled from approximately 100 facilities, such as emergency rooms and other settings where a physician is present to evaluate the patient for inclusion and exclusion criteria.
