Hybrid clotting factor means fewer injections, better disease control for hemophilia patients

A Phase III clinical trial led by UC Davis researchers has confirmed that a new coagulation factor (rFIXFc) dramatically reduces the number of injections needed to maintain effective clotting for HEMOPHILIA B patients.

The recombinant protein fuses clotting factor IX with an immunoglobulin (antibody) molecule, which prevents the body from rapidly metabolizing the hybrid protein. As a result, rFIXFc can be administered once a week, or even every two weeks, rather than every other (or every third) day. This extended half-life could have an enormous impact on hemophilia treatment.
