Trial summary

Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis, causing patients to be at high risk of major adverse cardiovascular and limb events. Therefore, single antiplatelet therapy is recommended when patients are symptomatic or have undergone revascularization. Read more about this study

About this study

Official title: DUAL Pathway Inhibition (Low-dose Rivaroxaban and Aspirin) as Compared to Aspirin Only to Improve Endothelial Function in Peripheral Artery Disease.

Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis, causing patients to be at high risk of major adverse cardiovascular and limb events. Therefore, single antiplatelet therapy is recommended when patients are symptomatic or have undergone revascularization. Rivaroxaban (2.5 mg twice a day) in addition to Aspirin (100 mg once a day) has shown to be effective in reducing morbidity and mortality from major cardiovascular and limb events in patients with stable peripheral or carotid artery disease compared to Aspirin alone. Although a higher rate of major bleeding was detected, the incidence of fatal or critical organ bleedings was not increased.

Endothelial dysfunction is one of the first signs of atherosclerosis and is related to major cardiovascular events. The level of vascular endothelial dysfunction can be measured using the carotid artery reactivity (CAR) test. The investigators hypothesized that a combination of low-dose rivaroxaban and antiplatelet therapy would improve endothelial function in PAD patients.

The investigators aim to study the effectiveness of this combination therapy in improving vascular endothelial function in patients with stable or symptomatic PAD.

Therefore the investigators will study two clinical cohorts of lower extremity PAD patients (n=159) with intermittent claudication (group A: Fontaine stages 1-2) or critical limb ischemia with pain at rest and/or foot ulcers (group B: Fontaine stages 3-4) who have an indication for single antiplatelet therapy.

Aspirin 100mg once a day + 2.5 mg rivaroxaban twice a day will be given during 3 months, preceded by a run-in period of Aspirin alone (100 mg once a day) as reference.

The change in proportion of patients with CAR-constriction from baseline (Aspirin alone) to 3 months after adding low dose rivaroxaban will be compared for both study groups (A and B).

Read the detailed description

Rationale: Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis, causing patients to be at high risk of major adverse cardiovascular events and major adverse limb events, including amputation. Therefore, clopidogrel or Aspirin depending on national guidelines, is recommended as single antiplatelet therapy when patients are symptomatic or have undergone revascularization. Anticoagulant therapies have not shown to be superior in PAD patients and have high rates of major bleedings. However, rivaroxaban (2.5 mg twice a day), an oral factor Xa inhibitor, in addition to Aspirin (100 mg once a day) has shown to be effective in reducing morbidity and mortality from coronary artery disease and major cardiovascular and limb events in patients with stable peripheral or carotid artery disease compared to Aspirin alone. Although a higher rate of major bleeding was detected, the incidence of fatal or critical organ bleedings was not increased.

Endothelial dysfunction is one of the first signs of atherosclerosis and is present before clinical symptoms appear. Endothelial dysfunction contributes to the progression of atherosclerosis and is related to major cardiovascular events. The level of vascular endothelial dysfunction can be measured using the carotid artery reactivity (CAR) test. This test measures the CAR in response to sympathic stimulation and can also be used to measure endothelial dysfunction in PAD patients and how a combination of rivaroxaban and Aspirin affects it. The investigators hypothesized that a combination of low-dose rivaroxaban and antiplatelet therapy would improve endothelial function in PAD patients.

Objective: To study the effectiveness of low-dose rivaroxaban with Aspirin in improving endothelial function in patients with stable or symptomatic PAD.

Study design: Two clinical cohort studies will be performed. Study population: Lower extremity PAD patients (n=159) with intermittent claudication (group A: Fontaine stages 1-2) or critical limb ischemia with pain at rest and/or foot ulcers (group B: Fontaine stages 3-4) who have an indication for single antiplatelet therapy are eligible for this study.

Intervention (if applicable): Aspirin 100mg once a day + 2.5 mg rivaroxaban twice a day (combination therapy). The use of Aspirin alone (100 mg once a day) during the run-in period is used as reference.

Main study parameters/endpoints: The primary outcome measure is the CAR after 3 months combination treatment. The change in proportion of patients with CAR-constriction from baseline (Aspirin alone) to 3 months after adding low dose rivaroxaban will be compared for both study groups (A and B). Serum endothelin-1 levels will be quantified as a marker for cardiovascular disease at baseline and 3 months after adding low dose rivaroxaban.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Rivaroxaban 2.5 Mg Oral Tablet in people with Peripheral Artery Disease, run by Radboud University Medical Center at 2 sites in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Carotid artery reactivity (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04218656, which also lists 22 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2022.
