Study to Gather Information About Proper Dosing and Safety of the Oral FXIa Inhibitor BAY 2433334 in Patients Following a Recent Non Cardioembolic Ischemic Stroke Which Occurs When a Blood Clot Has Formed Somewhere in the Human Body (But Not in the Heart) Travelled to the Brain.

Conditions

Acute Non-cardioembolic Ischemic Stroke

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 on top of antiplatelet therapy in patients following a recent non cardioembolic ischemic stroke which occurs when a blood clot that has not formed in the heart travelled to the brain. 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.

MeasureTime frameDescription
Efficacy-Number of Participants With Composite of Symptomatic Ischemic Stroke or Covert Brain Infarcts Detected by Magnetic Resonance Imaging (MRI)From baseline up to 26 weeksIschemic stroke was defined as either of : 1) Rapid onset (or present on awakening) of a new focal neurological deficit with clinical (\>24 hours symptoms/signs) or imaging evidence of infarction that was not attributable to a non-ischemic cause; 2) Acute worsening of an existing focal neurological deficit that was judged to be attributable to a new infarction or extension of the previous infarction in the same vascular territory, based on persisting symptoms/signs or imaging evidence of infarction and no evidence of a non-ischemic etiology. If imaging was inconclusive, persistent symptoms/signs must be significant (worsening of NIHSS score of 4 or more) and sustained (duration of ≥24 hours or until death). Covert brain infarcts were defined as incident infarcts detected by serial MRI in the absence of an adjudicated stroke consistent with the location of the infarct. MRI criteria for brain infarction were available in the MRI procedures manual.
Safety-Number of Participants With Composite of International Society on Thrombosis and Hemostasis (ISTH) Major Bleeding and Clinically Relevant Non-major (CRNM) BleedingFrom baseline up to 52 weeksISTH 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.

Death due to non-traumatic hemorrhage was included. Acute MI was used when there was evidence of myocardial necrosis in a clinical setting consistent with acute myocardial ischemia. According to MI Universal Definition from 2018 the diagnosis of MI required the combination of: 1) Presence of acute myocardial injury, and 2) Evidence of acute myocardial ischemia derived from the clinical presentation, electrocardiographic changes, or the results of myocardial or coronary artery imaging, or in case of post-mortem pathological findings irrespective of biomarker values. Systemic embolism was defined as abrupt vascular insufficiency associated with clinical or radiological evidence of arterial occlusion in the absence of other likely mechanisms (this did not include thromboembolism of the pulmonary vasculature or venous thrombosis).

Ischemic stroke was defined as either of : 1) Rapid onset (or present on awakening) of a new focal neurological deficit with clinical (\>24 hours symptoms/signs) or imaging evidence of infarction that was not attributable to a non-ischemic cause; 2) Acute worsening of an existing focal neurological deficit that was judged to be attributable to a new infarction or extension of the previous infarction in the same vascular territory, based on persisting symptoms/signs or imaging evidence of infarction and no evidence of a non-ischemic etiology. If imaging was inconclusive, persistent symptoms/signs must be significant (worsening of NIHSS score of 4 or more) and sustained (duration of ≥24 hours or until death). Covert brain infarcts were defined as incident infarcts detected by serial MRI in the absence of an adjudicated stroke consistent with the location of the infarct. MRI criteria for brain infarction were available in the MRI procedures manual.

Safety-Number of Participants With Intracerebral Hemorrhage (Non-traumatic)

Non-traumatic intracerebral hemorrhage was defined as a hemorrhagic stroke on the recurrent stroke CRF page that is in addition classified as a bleeding with bleeding site intracranial (-subarachnoid, -intraparenchymal \[excluding microbleeds\], or -intraventricular) and spontaneous causality of bleeding, excluding all symptomatic and hemorrhagic transformation (defined by the PT hemorrhagic transformation).
