The Quiz

What Is Factor It Forward?

The people behind IXINITY® [coagulation factor IX (recombinant)] have partnered with AmeriCares, a non-profit global health organization, to donate IXINITY to people with hemophilia B who can’t afford to be without it.

As part of our commitment to the hemophilia B community, we donate 10% of our sales to those in need. Now we’re expanding the program to include activities for the entire community—so that we can all Factor It Forward.

This is the power of IX.

How Does It Work?

How you can get involved

For every 10 units of IXINITY used, 1 unit is donated to those in need.

Important Safety Information

Indications and important safety information

What is IXINITY®?

IXINITY [coagulation factor IX (recombinant)] is a medicine used to replace clotting factor (factor IX) that is missing in adults and children at least 12 years of age with hemophilia B. Hemophilia B is also called congenital factor IX deficiency or Christmas disease. Hemophilia B is an inherited bleeding disorder that prevents clotting. Your healthcare provider may give you IXINITY to control and prevent bleeding episodes or when you have surgery.

IXINITY is not indicated for induction of immune tolerance in patients with hemophilia B.
