Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this clinical research study is to assess the safety and efficacy of rFIX for a minimum of 6 months in previously treated patients (PTPs) with hemophilia B (FIX:C ≤2%) during standard-of-care treatment (on-demand, prophylaxis, and through major and minor surgical procedures).
