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) That Can Lead to Heart-related Complications.
- Conditions
- Atrial Fibrillation (AF)

- Registration Number
- NCT04218266
- Lead Sponsor
- Bayer
- Brief 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.

- Primary Outcome Measures
Name Time Method Number of Participants With Composite of International Society on Thrombosis and Hemostasis (ISTH) Major Bleeding or Clinically Relevant Non-major (CRNM) Bleeding After the first administration of study intervention with an average administration of 12 weeks (but not starting after more than 2 days after the last administration) ISTH Major Bleeding criteria: 1. Fatal bleeding, and/or 2. Symptomatic bleeding in a critical area or organ (intracranial, intraocular, intraspinal, pericardial, retroperitoneal, intraarticular, or intramuscular with compartment syndrome), and/or 3. Clinically overt bleeding associated with a recent decrease in the hemoglobin level of ≥ 2 g/dL (20 g/L; 1.24 mmol/L) compared to the most recent hemoglobin value available before the event, and/or 4. Clinically overt bleeding leading to transfusion of 2 or more units of packed red blood cells or whole blood.
ISTH Clinically Relevant Non-Major Bleeding is considered any sign or symptom of hemorrhage that does not fit the criteria for the ISTH definition of major bleeding, but does meet at least one of the following criteria 1. requiring medical intervention by a healthcare professional. 2. leading to hospitalization or increased level of care. 3. prompting a face to face (i.e. not just a telephone or electronic communication) evaluation.
- Secondary Outcome Measures
Name Time Method Number of Participants With All Bleeding After the first administration of study intervention with an average administration of 12 weeks (but not starting after more than 2 days after the last administration) Adjudication of all bleeding events was performed by members of the Clinical events committee (CEC) who reviewed events in a blinded fashion and adjudicated and classified the following events in a consistent and unbiased manner according to the following classifications: ISTH (major, clinically relevant non-major and minor); Thrombolysis in myocardial infarction (TIMI major, minor, requiring medical attention, minimal); Bleeding Academic Research Consortium (BARC type 1, 2, 3, 5).
Number of Participants With ISTH Minor Bleeding After the first administration of study intervention with an average administration of 12 weeks (but not starting after more than 2 days after the last administration) All other overt bleeding episodes not meeting ISTH Major Bleeding criteria or clinically relevant non major bleeding were classified as minor bleeding.
Number of Participants With ISTH Major Bleeding After the first administration of study intervention with an average administration of 12 weeks (but not starting after more than 2 days after the last administration) ISTH Major Bleeding criteria: 1. Fatal bleeding, and/or 2. Symptomatic bleeding in a critical area or organ (intracranial, intraocular, intraspinal, pericardial, retroperitoneal, intraarticular, or intramuscular with compartment syndrome), and/or 3. Clinically overt bleeding associated with a recent decrease in the hemoglobin level of ≥ 2 g/dL (20 g/L; 1.24 mmol/L) compared to the most recent hemoglobin value available before the event, and/or 4. Clinically overt bleeding leading to transfusion of 2 or more units of packed red blood cells or whole blood.
Number of Participants of ISTH Clinically Relevant Non-major (CRNM) Bleeding After the first administration of study intervention with an average administration of 12 weeks (but not starting after more than 2 days after the last administration) ISTH Clinically Relevant Non-Major Bleeding is considered any sign or symptom of hemorrhage that does not fit the criteria for the ISTH definition of major bleeding, but does meet at least one of the following criteria 1. requiring medical intervention by a healthcare professional. 2. leading to hospitalization or increased level of care. 3. prompting a face to face (i.e. not just a telephone or electronic communication) evaluation.
