Bleeding With Asundexian Versus Placebo in Patients With Noncardioembolic Ischemic Stroke or High-Risk TIA: OCEANIC-STROKE Randomized Trial

Authors' conclusion

Asundexian added to antiplatelet therapy reduced ischemic stroke without significantly increasing major, major or CRNM, or any bleeding. Lower gastrointestinal bleeding was more frequent with asundexian, whereas treatment effects on major and major or CRNM bleeding were consistent across prespecified subgroups.
