Major bleeding with hemodynamic instability-gastrointestinal, retroperitoneal, genitourinary tract bleedġ. ANDEXXA ® (coagulation factor Xa (recombinant), inactivated-zhzo).

Major trauma-blunt or penetrating injury.

Bleeding at a critical site-intraocular, pericardial, intraspinal, intra-articular.

Intracranial hemorrhage-intracerebral, subdural, subarachnoid.

Life-threatening or uncontrolled factor Xa (FXa) inhibitor–related bleeds can occur in several sites 2-4: *ANDEXXA has not been shown to be effective for, and is not indicated for, the treatment of bleeding related to any factor Xa (FXa) inhibitors other than apixaban or rivaroxaban. Continued approval for this indication may be contingent upon the results of studies that demonstrate an improvement in hemostasis in patients. An improvement in hemostasis has not been established.

This indication is approved under accelerated approval based on the change from baseline in anti-factor Xa (FXa) activity in healthy volunteers. ANDEXXA ® (coagulation factor Xa (recombinant), inactivated-zhzo) is a recombinant modified human factor Xa (FXa) protein indicated for patients treated with rivaroxaban or apixaban, when reversal of anticoagulation is needed due to life-threatening or uncontrolled bleeding.
