Thrombin generation (TG) tested in vitro was consistent with resistance to high concentrations of rFVIIa but yielded good response to combinations of low doses of rFVIIa+FEIBA. In a desperate attempt to control the bleeding, concomitant therapy of 25 U/kg FEIBA and 40µg/kg rFVIIa was infused and resulted in arrest of bleeding within minutes. Over a span of about one year the patient has been successfully treated by this combination for more than 200 bleeding episodes in muscles and joints.
