Milvexian with Antiplatelet Therapy after Acute Coronary Syndrome Event

Listen to this summary

This study aimed to evaluate the efficacy and safety of milvexian, an oral factor XIa inhibitor, when added to standard antiplatelet therapy in patients within 7 days of an acute coronary syndrome event. The trial found that milvexian did not significantly reduce the risk of cardiovascular death, myocardial infarction, or ischemic stroke compared to placebo, and it did not increase the risk of serious bleeding events. Consequently, the trial was terminated for futility after an interim analysis.
