Patients presenting with symptomatic PAD are at high risk of ischaemic stroke, myocardial infarction and progression of the PAD.2 Recent data suggest that half of chronic total occlusions occurring below the knee are thomboembolic in origin, and not due to in situ atherosclerosis as believed previously.3 Accordingly, treating PAD patients with antithrombotic agents may have benefits in reducing major adverse cardiovascular events (MACE).8
The COMPASS (Cardiovascular Outcomes for People Using Anticoagulation Strategies) trial demonstrated that adding rivaroxaban 2.5 mg twice daily to aspirin 100 mg once daily in patients with PAD reduced MACE compared to aspirin alone.4 The results of COMPASS were reviewed by the National Institute for Health and Care Excellence (NICE) in a technology appraisal guidance published on 17th October 2019 entitled ‘Rivaroxaban for preventing atherothrombotic events in people with coronary or peripheral artery disease’.5 Rivaroxaban plus aspirin was recommended within its marketing authorisation, as an option for preventing atherothrombotic events in adults with coronary artery disease or symptomatic PAD who are at high risk of ischaemic events mirroring the entry criteria for the COMPASS study.

Notes on dosing recommendations from Xarelto® ▼ (rivaroxaban) SmPC (Summary of Product Characteristics)
Xarelto 2.5 mg twice daily, coadministered with a daily dose of 75–100 mg aspirin, is indicated for the prevention of atherothrombotic events in adult patients with coronary artery disease (CAD) or symptomatic peripheral artery disease (PAD) at high risk of ischaemic events.
The COMPASS (Cardiovascular Outcomes for People Using Anticoagulation Strategies) trial discussed in this supplement compared both Xarelto 2.5 mg twice-daily plus aspirin and also Xarelto 5 mg twice-daily without aspirin, versus aspirin alone. Results for both comparisons are provided reflecting the original study publication.
Please note, however, that Xarelto 5 mg twice-daily is not a licensed dosage regimen for the above, nor for any other therapeutic indication.
