Study to gather information about the proper dosing of the oral FXIa inhibitor BAY 2433334 and to compare the safety of the study drug to apixaban, a non-vitamin K oral anticoagulant (NOAC) in patients with irregular heartbeat (atrial fibrillation).

Multicenter, randomized, active comparator-controlled, double-blind, double-dummy, parallel group, dose-finding Phase 2 study to compare the safety of the oral FXIa inhibitor BAY 2433334 to apixaban in patients with atrial fibrillation - PACIFIC-AF

Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate that the oral FXIa inhibitor BAY 2433334 when compared to apixaban leads to a lower incidence of bleeding in participants with AF;Secondary Objective: Not applicable;Primary end point(s): Composite of ISTH major and clinically relevant non-major bleeding;Timepoint(s) of evaluation of this end point: From Visit 2 (randomization visit) until Visit 7 (safety follow-up visit)

Secondary

MeasureTime frame
Secondary end point(s): Secondary Safety Endpoints: • All bleeding • ISTH major bleeding • ISTH clinically relevant non-major bleeding • ISTH minor bleeding ;Timepoint(s) of evaluation of this end point: From Visit 2 (randomization visit) until Visit 7 (safety follow-up visit)
