简要总结

To evaluate the safety (acute adverse effects associated with infusions, and inhibitor development), pharmacokinetics (PK), and efficacy with respect to breakthrough bleeding and control of hemorrhaging during prophylaxis of IB1001 in subjects with hemophilia B.

详细描述

Primary Objectives:

  • to evaluate safety of IB1001 within the first 50 exposure days,
  • to determine IB1001 pharmacokinetics (PK), and
  • to assess efficacy of IB1001 prophylaxis with respect to breakthrough bleeding and with respect to control of hemorrhaging in subjects with severe hemophilia B within the first 50 exposure days

Secondary Objectives:

  • to evaluate long-term safety of IB1001; and
  • to evaluate long term efficacy of IB1001.

Exploratory Objectives:

结局指标

主要结局

Number of study subjects with adverse events

时间窗: Within 6 months

Information on adverse events is collected after each infusion of study drug by a study subject. Assessment of adverse events is then performed by an investigator after 5 infusions of study drug, 1 month, 2 months, 3 months and 6 months of study drug treatment.

次要结局

  • Number of bleeding episodes divided by number of months of observation(Within 12 months)
