Milvexian (BMS-986177/JNJ-70033093) is an orally bioavailable, small-molecule, reversible, and direct antagonist of Factor XIa (FXIa). It exhibits potent inhibitory activity across species, with Ki values of 0.11 nM for human, 0.38 nM for rabbit, and 0.64 nM for dog. By targeting FXIa, Milvexian selectively inhibits the intrinsic pathway of the coagulation cascade. It demonstrates robust antithrombotic efficacy in various in vitro and in vivo models while maintaining a favorable safety profile regarding bleeding risk. It is a critical tool for investigating novel anticoagulant strategies in thrombosis and cardiovascular research.

| Description | Milvexian (BMS-986177/JNJ-70033093) is an orally bioavailable, small-molecule, reversible, and direct antagonist of Factor XIa (FXIa). It exhibits potent inhibitory activity across species, with Ki values of 0.11 nM for human, 0.38 nM for rabbit, and 0.64 nM for dog.

It demonstrates robust antithrombotic efficacy in various in vitro and in vivo models while maintaining a favorable safety profile regarding bleeding risk. It is a critical tool for investigating novel anticoagulant strategies in thrombosis and cardiovascular research. |
| In vitro | Milvexian (~10 μM) prolongs aPTT in human plasma, confirming selective blockade of the intrinsic coagulation pathway. It does not affect platelet aggregation induced by ADP or collagen, indicating that its antithrombotic effect is coagulation-specific, offering a mechanistic advantage in reducing bleeding risk [1]. |
| In vivo | In a rabbit thrombosis model, Milvexian dose-dependently maintained carotid blood flow (32–76%) and reduced thrombus weight (15–70%) following i.v. administration. Orally dosed at 20 mg/kg, it achieved a plasma concentration of 2000 nM at 1 h, demonstrating favorable PK [1][2]. |
