Background: The COMPASS trial demonstrated that in patients with peripheral arterial disease the combination of rivaroxaban and aspirin compared with aspirin reduces the risk of major adverse limb events, but it is not known whether this combination can also improve symptoms in patients with intermittent claudication. The primary objective of this study is to evaluate the effect of the combination on intermittent claudication distance.~Study design: Eighty-eight patients with intermittent claudication will be randomized to receive rivaroxaban 2,5 mg twice daily plus aspirin 100 mg once daily or aspirin 100 mg once daily for 24 weeks. The primary outcome is the change in claudication distance from baseline to 24 hours as measured by 6 minutes walking test and treadmill test. The main safety outcome is the incidence of major bleeding according to ISTH criteria.~Summary: The COMPASS CLAUDICATION trial will provide high-quality evidence regarding the effect of the combination of rivaroxaban and aspirin on claudication distance in patients with peripheral arterial disease.
This trial is evaluating if rivaroxaban 2.5 mg BID and aspirin 100 mg OD compared to aspirin alone improves on intermittent claudication distance in PAD patients.
