Betrixaban is an oral Factor Xa inhibitor that has been specifically designed for chronic, once-a-day treatment with a long half-life. Betrixaban is minimally excreted through the kidneys and is the only new oral anticoagulant currently being studied in patients with severe and moderate renal impairment without dose adjustment. As a result, it has the potential to become the only novel oral anticoagulant available for patients with severe renal disease. In addition, betrixaban is not extensively metabolized by cytochrome P450, which may result in reduced potential for drug-drug interactions.
Portola is currently conducting EXPLORE-Xa, a Phase II dose-ranging clinical trial evaluating betrixaban for stroke prevention in 500 patients with atrial fibrillation (SPAF), which is scheduled to be fully enrolled by the end of 2009.
In addition to SPAF, betrixaban could be further developed in other indications, including the treatment or prevention of life threatening blood clots in patients undergoing high-risk orthopedic and general surgery, those with acute and chronic medical illness, and in patients with acute coronary syndrome (ACS).
