A clinical study to evaluate the safety and efficacy of rivaroxaban in patients with mildCOVID-19 that are at high risk of serious complications such as blood clots that can formin the organs of the body. It is hoped that by intervening early with a drug which thinsthe blood that may prevent progression of mild symptoms to serious complications andsevere disease.
