New Oral Anti-Xa Anticoagulant?

I received a message from Eric Hardy, a 1990s graduate of our University of Alabama at Birmingham CLS program and now a physician assistant practicing in the area. A McNeil Labs representative was advocating for one of the new oral anti-Xa anticoagulants . I have seen no announcement nor ads indicating any of the new oral drugs have been released for the US market. What is their current status?
