Mechanism of action

BT524 works by inhibiting TFPI, a natural anticoagulant that suppresses the tissue factor-initiated coagulation cascade. By blocking TFPI, the drug allows increased thrombin generation, which promotes clot formation and hemostasis. This mechanism is intended to improve bleeding control in patients with severe bleeding disorders or those requiring hemostatic support.
