Switching From DAPT to Dual Pathway Inhibition With Low-dose Rivaroxaban in Adjunct to Aspirin in Patients With Coronary Artery Disease

Completed · Phase 4

Conditions studied: Coronary Artery Disease

In brief

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).

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Willing and able to provide written informed consent
• Above 18 years of age
• Have known CAD and have completed their required duration of standard of care DAPT (aspirin in combination with either clopidogrel, prasugrel, or ticagrelor) and still be on treatment:
• ≥ 6 months after an elective PCI
• ≥ 12 months after experiencing an ACS (irrespective of revascularization at the time of ACS; thus patients treated by PCI, CABG, or medically managed can be considered)

You may not qualify if…

• Deemed to be at high risk of bleeding, active bleeding or history of major bleeding Stroke within 1 month or any history of hemorrhagic or lacunar stroke
• Estimated glomerular filtration rate <15 mL/min by MDRD equation
• Need for dual antiplatelet therapy, other non-aspirin antiplatelet therapy, or oral anticoagulant therapy
• Known non-cardiovascular disease that is associated with poor prognosis (e.g., metastatic cancer) or that increases the risk of an adverse reaction to study interventions.
• History of hypersensitivity or known contraindication for rivaroxaban.
• Systemic treatment with strong inhibitors of both CYP 3A4 and p-glycoprotein (e.g., systemic azole antimycotics, such as ketoconazole, and human immunodeficiency virus [HIV]-protease inhibitors, such as ritonavir), or strong inducers of CYP 3A4, i.e.
• rifampicin, rifabutin, phenobarbital, phenytoin, and carbamazepine
• Any known hepatic disease associated with coagulopathy
• Subjects who are pregnant, breastfeeding, or are of childbearing potential, and sexually active and not practicing an effective method of birth control (e.g. surgically sterile, prescription oral contraceptives, contraceptive injections, intrauterine device, double barrier method, contraceptive patch, male partner sterilization)
• Concomitant participation in another study with investigational drug
• Known contraindication to any study related procedures
• Hemoglobin ≤9 mg/dL
• Platelet count <80x106/mL
