Portola is developing AndexXa as a universal reversal agent for patients anticoagulated with an oral or injectable Factor Xa inhibitor who experience a serious uncontrolled or life-threatening bleeding event or who require urgent or emergency surgery. The BLA seeks initial approval of AndexXa for reversal of the anticoagulant effects of apixaban and rivaroxaban in patients experiencing uncontrolled or life-threatening bleeding.
In 2016, approximately 90,000 patients in the U.S. treated with oral Factor Xa inhibitors were subsequently admitted to the hospital due to bleeding. Including patients taking the injectable Factor Xa inhibitor enoxaparin, it is estimated that more than 150,000 U.S. patients could benefit from an antidote annually. Currently, there are no approved Factor Xa inhibitor antidotes.
