Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Rivaroxaban (Xarelto, BAY59-7939) | Subjects randomized to treatment with rivaroxaban received rivaroxaban 20 milligram (mg) orally once daily. Subjects with moderate renal impairment \[i.e., Creatinine clearance (CrCl) of 30 to 49 milliliter per minute (mL/min), inclusive\] at screening received the adjusted dose of 15 mg once daily. The duration of the treatment period for a given subject depended on the cardioversion strategy. For subjects in the Direct Cardioversion Strategy, the cardioversion procedure was performed within 1-5 days after randomization. Rivaroxaban was given for 1-5 days before planned direct cardioversion and for 42 days thereafter. Subjects in the Delayed Cardioversion Strategy received rivaroxaban for 21 (+4) to 56 (+4) days prior to cardioversion and for 42 days thereafter. The investigator assessed whether or not long-term anticoagulation was warranted and treated the subject according to standard of care. Then subjects entered 30-day follow-up period. | 2 | 978 | OG000 |
| Group 2 | Vitamin K Antagonist (VKA) | Subjects assigned to treatment with VKA received VKA orally once daily titrated to a target INR of 2.5 (range 2.0-3.0, inclusive). The specific VKA was given by the investigator based on local standard of practice. For all subjects randomized to receive VKA, the investigator assessed if a parenteral anticoagulant drug, particularly before cardioversion, was needed as bridging therapy with VKA as standard of care (until target INR was achieved). The duration depended on the cardioversion strategy. For subjects in the Direct Cardioversion Strategy, cardioversion was performed within 1-5 days after randomization. VKA was given for 1-5 days before it and for 42 days thereafter. Subjects in the Delayed Cardioversion Strategy received VKA for 21 (+4) to 56 (+4) days before cardioversion and for 42 days thereafter. The investigator assessed if long-term anticoagulation was warranted and treated the subject according to standard of care or not. Then subjects entered 30-day follow-up period. | 3 | 492 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants With Composite of Strokes and Non-central Nervous System Systemic Embolisms
- Description
Stroke and Non-CNS Embolism were adjudicated and confirmed by CEC. Stroke included hemorrhagic and ischemic infarction. Non CNS systemic embolism included emboli in peripheral arterial of the upper and lower extremities, ocular and retinal (pulmonary embolism and MI were excluded from the category). Number of subjects with composite events were reported.
- Time frame
From randomization to the date of last dose of study drug +2 days for subjects who completed planned treatment or the earlier date [last planned dose, follow-up visit at the end of 30-day follow-up period] for subjects who prematurely stopped treatment
- Population
The primary population for the efficacy analysis was the mITT population. mITT population included all the randomized subjects in whom a LA/LAA thrombus was not diagnosed during a TEE performed before the first planned cardioversion in the study.
