Study Summary

The primary objective of the study is to evaluate the safety of Recombinant Human Coagulation Factor IX Fc Fusion Protein (rFIXFc) in previously treated pediatric subjects with hemophilia B. Secondary objectives of this study in this study population are as follows: to evaluate the efficacy of rFIXFc for prevention and treatment of bleeding episodes; to evaluate and assess the pharmacokinetics (PK) of rFIXFc; to evaluate rFIXFc consumption for prevention and treatment of bleeding episodes

Primary Outcome

An inhibitor test result ≥ 0.6 Bethesda units (BU)/mL, confirmed on 2 separate samples drawn 2 to 4 weeks apart, was considered positive. Both tests were to be performed by the central laboratory using the Nijmegen-modified Bethesda Assay. Incidences were summarized for any positive inhibitor for participants with ≥ 50 exposure days (EDs) to rFIXFc. In addition, the incidence for all participants, regardless of their EDs to rFIXFc, was also summarized. An exact 95% CI for the proportion of parti
