Clinical Trial 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.

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

2. Age =18

3. Increased risk of stroke by any of the following

• CHA2DS2-VASc score = 2 OR
• Moderate/Severe mitral stenosis with valve area =2.0 cm2 OR

4. Heart Rhythm *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.

Exclusion Criteria:

1. Refusal to give informed consent

2. Actively involved in any study that would compromise the protocol of INVICTUS Trial

3. Severe co-morbid condition with life expectancy < 1 year

4. Other serious condition(s) or logistic factors likely to interfere with study participation or with the ability to complete the trial, as appropriate to country or region.

5. Likely to have valve replacement surgery within 6 months

9. Serious bleeding in the past six months or at high risk for bleeding

10. Moderate to severe hepatic impairment

11. Ongoing need for dual antiplatelet therapy (patients with on-going aspirin therapy =100 mg per day are not excluded)

12. Ongoing need for dual strong inhibitors of CYP-3a4 or p-glycoprotein inhibitor.

13. Received an investigational drug in the past 30 days

14. Patients considered unsuitable for trial inclusion because of unwillingness to attend follow up visits

15. Women who are pregnant and/or breastfeeding

16. Women of child bearing age who do not use an effective form of birth control.

Intervention

Drug:
• Rivaroxaban (20 mg)
