Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Participant must be 45 years of age and older at the time of signing the informed consent
* Non-cardioembolic ischemic stroke with

* persistent signs and symptoms of stroke lasting for = 24 hours OR
* acute brain infarction documented by computed tomography (CT) or MRI AND

Summary
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.
