COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

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

enrolled. Participants undergoing thrombolysis or endovascular therapy
(mechanical thrombectomy) can be enrolled but at the earliest 24 hours after the
intervention

- Randomization within 48 hours after the onset of symptoms of the index event (or after
patients were last known to be without symptoms in case of wake-up stroke)

- Ability to conduct an MRI either before randomization or within 72 hours after
randomization

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.
