Brief Summary

Patients with moderate to severe COVID-19 present a very high risk of thromboembolic disease.This multicenter, prospective, randomized, event-driven study evaluates rivaroxaban compared with standard of care with low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH) at prophylactic doses comparing D-dimer levels and the seven-category ordinal scale recommended by the WHO 7 days post randomization in patients with moderate to severe COVID-19.

Experimental intervention/Index test:

Patients randomized into the rivaroxaban arm will receive rivaroxaban 20 mg once daily (OD) until day 7 post randomization or hospital discharge, whichever occurs later, followed by a 28-day-phase of prophylactic anticoagulation with rivaroxaban 10mg OD. Subjects with an eGFR between 30 and 50ml/min/1,73m2, will receive 15mg instead of 20mg OD.

Control intervention/Reference test:

The control group will receive standard of care including LMWH or UFH as thromboprophylaxis.

Duration of intervention per patient:

The total duration of the study treatment is flexible. For out-patients 7 days of therapeutic anticoagulation will be accompanied by 28 days-phase of prophylactic anticoagulation, summing up to 35 days. For subjects that require hospitalization, the duration of therapeutic anticoagulation will be at least 7 days or prolonged until discharge if hospitalized for more than 7 days post randomization.

After discharge from the hospital the subject receives 28 days of thromboprophylaxis with rivaroxaban. No study medication will be given past day 60 post randomization. This adds up to a study duration between 35 and 60 days depending on the duration of the hospital stay.

Follow-up per patient:

The study has a follow-up of 60 days.

Experimental and/or control off label or on label in Germany:

Rivaroxaban has been approved for multiple indications worldwide. Over 100,000 subjects have been studied from Phase 1 through multiple large Phase 4 studies in multiple settings, e.g. for the reduction in the risk of stroke and systemic embolism in arterial fibrillation, deep vein thrombosis and pulmonary embolism, major cardiovascular events. The drug had not been studied in patients with COVID-19 as an anticoagulant agent, yet.

Study Groups

Rivaroxaban

Subjects will receive treatment with rivaroxaban. (for more information see intervention description)

Group Type: EXPERIMENTAL

Rivaroxaban

Intervention Type: DRUG

Treatment with Rivaroxaban 20 mg (15 mg for subjects with an eGFR ≥30 mL/min/1.73m2 and \<50 mL/min/1.73m2) once daily (OD) for at least 7 days. In case of hospitalization for more than 7 days, the therapeutic treatment with rivaroxaban will be continued for the duration of the hospital stay until discharge. After at least 7 days of therapeutic treatment with rivaroxaban or after hospital discharge, the study dose of rivaroxaban will be adjusted as follows. Patients randomized to the rivaroxaban study arm will reduce daily dosage to 10 mg OD, provided that they were not diagnosed with a condition requiring continued therapeutic anticoagulation. Thromboprophylaxis therapy will be given for 28 days up to day 35 post randomization or even longer. If the patient cannot be discharged from the hospital prior to day 35 post randomization, the thromboprophylaxis phase will also start upon hospital discharge, but is then shorter than 28 days, because the study ends at day 60 post randomization.

Eligibility Criteria

Inclusion Criteria

• Subject must be willing, understanding and able to provide written informed consent
• Subject must be a man or a woman with age > 18 years at screening
• Subject must have an active moderate to severe COVID-19 confirmed by

o A positive SARS-CoV-2 PCR test in the last 14 days

• At least one of the following features should be present

• D-Dimer elevation > 1.5 ULN (age adjusted cut-offs) AND/OR
• Cardiac injury reflected by an elevation in hs-cTnT > 2.0 upper limit of normal (ULN) AND at least one of the following conditions:

• Known coronary artery disease (CAD)
• Known diabetes mellitus
• Active smoking
• A woman of childbearing potential must have a negative serum or urine pregnancy test before randomization occurs. Before randomization, a woman must be either:

• Postmenopausal, defined as >45 years of age with amenorrhea for at least 18 months,
• If menstruating:

• If heterosexually active, practicing a highly effective method of birth control, including hormonal prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, double-barrier method [(e.g., condoms, diaphragm, or cervical cap, with spermicidal foam, cream, or gel)], or male partner sterilization, consistent with local regulations regarding use of birth control methods for subjects participating in clinical studies, for the duration of their participation in the study, or
• Surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), or

Exclusion Criteria

• Subject has a very high bleeding risk: Any condition that, in the opinion of the investigator, contraindicates anticoagulant therapy or would have an unacceptable risk of bleeding, such as, but not limited to, the following:
