INVestIgation of rheumatiC AF Treatment Using Vitamin K Antagonists, Rivaroxaban or Aspirin Studies, Non-Inferiority

Phase 3
Completed
Conditions
Rheumatic Heart Disease
Interventions
Drug: Rivaroxaban (20 mg)
Drug: Vitamin K antagonists (VKA)
Registration Number
NCT02832544
Lead Sponsor
Population Health Research Institute
Brief Summary

This program is a comprehensive evaluation of rheumatic valvular heart disease (RVHD), Atrial fibrillation (AF)/flutter and stroke.

A prospective, randomized, parallel group, open-label clinical trial of rivaroxaban versus standard vitamin K antagonists (VKA) therapy to evaluate non-inferiority of rivaroxaban to VKA, with testing for superiority if non-inferiority is satisfied.

Detailed Description

Non-Inferiority Trial of rivaroxaban versus VKAs: 4,500 patients

Inclusion Criteria:

1. RVHD diagnosed by echocardiography at any time prior to enrollment

2. Age ≥18

3. Increased risk of stroke by any of the following

1. CHA2DS2-VASc score ≥ 2 OR

2. Moderate/Severe mitral stenosis with valve area ≤2.0 cm2 OR

3. Left atrial spontaneous echo contrast OR

4. Left atrial thrombus

4. Heart Rhythm a) AF or Flutter should be documented on baseline 12-lead ECG, or on a previous 12-lead ECG, Holter monitor, in-hospital ECG rhythm strip or Pacemaker or ICD electrogram.

Treatment:

Patients will be randomized either to receive rivaroxaban or any approved VKA. Treatment will be open-label.

1. Rivaroxaban Arm

* Rivaroxaban 20 mg once daily

* Rivaroxaban 15 mg once daily (for patients with an creatinine clearance ≥15 and \<50 ml/min)

2. VKA Arm

* Any VKA approved for use in the participating country

* VKA titrated to achieve an INR of 2.0-3.0
