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)

• Status: Completed
• Trial end date: 2021-10-08
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to try to find the best dose of the new drug BAY 2433334 to give to participants and to look at how well BAY 2433334 works in patients with irregular heartbeat (atrial fibrillation) that can lead to blood clots, stroke and other heart-related complications. In addition researchers want to compare the safety of the study drug to apixaban, a non-vitamin K oral anticoagulant (NOAC) in patients with atrial fibrillation. This study is also done to learn how the drug in this study moves into, through and out of the body. BAY 2433334, works by blocking a step of the blood clotting process in our body and thins the blood and is a so called oral FXIa inhibitor.

Apixaban, works by reducing the production of blood clotting factors in our body and thins the blood and is a so called non-vitamin K oral anticoagulant (NOAC). Thinning the blood can prevent you from blood clots which can cause a stroke.
