Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the prospective, randomized cohort in this study is to assess the safety and efficacy of 2 apixaban treatment strategies (uninterrupted versus interrupted) in subjects planned to undergo catheter ablation for the treatment of non-valvular atrial fibrillation (NVAF).

Simultaneously, a retrospective cohort of 300 warfarin-treated individuals, identified by chart review, who are matched to the prospective randomized subjects, will be identified. The purpose of the retrospective warfarin cohort is to compare the efficacy and safety of warfarin(the current clinical practice) to that of apixaban (uninterrupted, interrupted, combined uninterrupted and interrupted).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prospective, Randomized Cohort

Subjects undergoing ablation for NVAF who meet all eligibility criteria and sign informed consent will be enrolled into the study. Subjects will be treated with apixaban for ≥21 days prior to the ablation procedure (for subjects already on apixaban for ≥21 days, it is not necessary to wait 21 days before the ablation procedure. Apixaban dose will be 5 mg b.i.d. per product label, or 2.5 mg b.i.d. in subjects with 2 or more of the following: age ≥80 years, body weight ≤60 kg, or serum creatinine ≥1.5 mg/dL.

Eligible subjects will then be randomized in a 1:1 ratio to 2 peri-procedural treatment strategies:

* Uninterrupted treatment: administer the evening apixaban dose on the day prior to the procedure; administer the morning apixaban dose on the day of the procedure; administer heparin bolus before transseptal puncture to maintain a target activated clotting time \[ACT\] \> 300 seconds; administer the evening apixaban dose after the procedure if there were no peri-procedural complications that necessitate withholding anticoagulation for longer duration.
* Interrupted treatment: administer the evening apixaban dose on the day prior to the procedure; do not administer the morning apixaban dose on the day of the procedure; administer heparin bolus before transseptal puncture to maintain a target ACT \> 300 seconds; administer the evening apixaban dose after the procedure if there were no peri-procedural complications that necessitate withholding anticoagulation for longer duration.

Randomization will take place prior to the procedure (on the day of the procedure or up to 3 days prior to the procedure) and will be stratified by site.

It is anticipated that up to 360 subjects may be enrolled in order to evaluate a total of 300 randomized subjects (150 subjects per treatment arm):

Randomized subjects will continue treatment with apixaban for 1 month post procedure.

Retrospective, Warfarin Cohort In addition, a chart review of 300 warfarin-treated patients who underwent catheter ablation for NVAF on or after September 1, 2013 in the enrolling centers and who have documented follow-up in the medical record for ≥ 30 days post-ablation procedure will be performed. Patient records for warfarin-treated individuals who meet the applicable inclusion/exclusion criteria and who are matched 1:1 to a subject in the prospective, randomized cohort for age (+/- 5 years), gender and atrial fibrillation (AF) type (paroxysmal vs. persistent), will be identified. Sites will document key demographic and outcome variables. This review will be performed in a blinded manner such that site personnel are blinded to the outcome of each retrospective subject during the subject selection process. Only pre-existing data will be collected for the analysis of this cohort.

2. \>18 years of age.
3. NVAF with planned catheter ablation treatment.
4. Planned anticoagulant treatment for at least 1 month after the index procedure.
