Multicenter, Randomized, Placebo-controlled, Double-blind, Parallel Group, Dose-finding Phase 2 Study to Evaluate Efficacy and Safety of BAY2433334 in Patients Following an Acute Non-cardioembolic Ischemic Stroke

Efficacy-Number of Participants With Composite of Symptomatic Ischemic Stroke or Covert Brain Infarcts Detected by Magnetic Resonance Imaging (MRI)

时间窗: From baseline up to 26 weeks

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 Composite of International Society on Thrombosis and Hemostasis (ISTH) Major Bleeding and Clinically Relevant Non-major (CRNM) Bleeding

时间窗: From baseline up to 52 weeks

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.
