Leverkusen/Berlin, November 19, 2023 – OCEANIC-AF, a phase III study investigating asundexian compared to apixaban (a direct oral anticoagulant) in patients with atrial fibrillation at risk for stroke is being stopped early. This decision is based on the recommendation of the study’s Independent Data Monitoring Committee (IDMC) as part of ongoing surveillance which showed an inferior efficacy of asundexian versus the control arm. Bayer will further analyze the data to understand the outcome and publish the data.

Available safety data are consistent with previously reported safety profiles of asundexian. The IDMC recommends continuing the OCEANIC-STROKE phase III study as planned. Appropriate measures will be taken to close the OCEANIC-AF study and patients will be contacted by their treating physicians/investigators to discuss next steps.

Asundexian is an investigational agent and has not been approved by any health authority for use in any country, for any indication.
