<jats:p>A fusion protein genetically linking recombinant human coagulation FIX with recombinant human albumin (rIX-FP) has been developed with an improved PK profile, improving hemophilia B treatment by allowing less frequent dosing than required with standard plasma-derived (pd) and recombinant (r) FIX products. The PROLONG-9FP clinical program has evaluated the use of rIX-FP for prophylaxis and on-demand treatment of bleeding in patients with severe hemophilia B. The clinical program is comprised of 5 clinical studies, including four completed studies (a Phase I pharmacokinetic (PK) study, a Phase II study, and two Phase III studies in adults and children), and an ongoing extension study, which includes previously untreated patients. Over 100 subjects from 42 hemophilia treatment centers in 12 countries have participated in the PROLONG-9FP clinical program. Here, we report on the long-term safety and efficacy of rIX-FP in 15 subjects who have continuously participated in 3 clinical studies (Phase II, Phase III and the on-going Phase III extension studies) over a period of 4 years.</jats:p>
<jats:p>Subjects began either weekly prophylaxis treatment or on-demand treatment with rIX-FP in the Phase II 2004 study, and continued that treatment regimen in the Phase III 3001 study.
