About this study

Official title: Switching From Standard of Care Dual Antiplatelet Treatment (DAPT) Regimens With Aspirin Plus a P2Y12 Inhibitor to Dual Pathway Inhibition (DPI) With Low-dose Rivaroxaban in Adjunct to Aspirin in Patients With Coronary Artery Disease: The Switching Anti-Platelet and Anti-Coagulant Therapy (SWAP-AC) Study

Recent studies indicate that anti-factor-Xa inhibition with low-dose rivaroxaban may have a role in the reduction of ischemic recurrences in patients with atherosclerotic disease manifestations. The objectives of this investigation are to assess the feasibility of switching from a DAPT to DPI regimen and to compare the pharmacodynamic profiles of these treatment regimens. This will be a prospective study conducted in cohorts of patients with CAD on treatment per standard of care with DAPT. Patients will be randomized to either maintain DAPT or to DPI. DPI consists in treatment with aspirin (81mg/qd) plus rivaroxaban (2.5mg/bid).

Read the detailed description

Recent studies indicate that anti-factor-Xa inhibition with low-dose rivaroxaban may have a role in the reduction of ischemic recurrences in patients with atherosclerotic disease manifestations. In the COMPASS trial, patients with stable coronary or peripheral artery disease and no indication for oral anticoagulation or dual antiplatelet therapy (DAPT) were randomized to rivaroxaban 2.5 mg bid in combination with aspirin, rivaroxaban 5 mg bid monotherapy or aspirin monotherapy. The study showed a significant 24% relative reduction in ischemic outcomes with rivaroxaban 2.5 mg bid plus aspirin combination strategy compared with aspirin alone. These observations have raised practical considerations on how to implement the results of the COMPASS trial in clinical practice particularly for patients who are completing a minimum duration of DAPT and contemplating between continuing with a DAPT regimen versus switching to a dual pathway inhibition (DPI) regimen with aspirin plus rivaroxaban. Therefore, the objectives of this investigation are to assess the feasibility of switching from a DAPT to DPI regimen and to compare the pharmacodynamic profiles of these treatment regimens. This will be a prospective study conducted in cohorts of patients with CAD on treatment per standard of care with DAPT. Patients will be randomized to either maintain DAPT or to DPI. DPI consists in treatment with aspirin (81mg/qd) plus rivaroxaban (2.5mg/bid).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximal Platelet Aggregation (MPA%) by Light Transmittance Aggregometry (LTA)

    The primary end point of this study will be the comparison of MPA% measured by LTA using the CATF cocktail as agonist between DAPT and low-dose rivaroxaban plus aspirin for each DAPT regimen

    Measured: 30 days

Model description
Patients treated with either aspirin (81mg/qd) plus clopidogrel, aspirin (81mg/qd) plus ticagrelor (90mg/bid), or aspirin (81mg/qd) plus prasugrel (10mg/bid) will be identified. Each cohort will be randomized 1:1 to either maintain DAPT or to DPI. DPI consists in treatment with aspirin (81mg/qd) plus rivaroxaban (2.5mg/bid). Patients randomized to DAPT will continue their guideline recommended DAPT regimens.

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 5 inclusion and 13 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 26 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 26 Apr 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Maximal Platelet Aggregation (MPA%) by Light Transmittance Aggregometry (LTA) (time frame: 30 days). 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 NCT04006288, which also lists 2 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 26 Apr 2023.
