Clinical Trial Summary

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).


Clinical Trial 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). ;
