ClinConnect Summary

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 dai...
