Background
Flebogamma® 5% dual inactivation and filtration (DIF) is the next generation of Flebogamma®. Flebogamma® was first licensed in 1992. The new preparation features additional viral inactivation and removal steps to enhance safety margins.
Objective
The purpose of this study was to evaluate the efficacy, safety, and pharmacokinetics of Flebogamma® 5% DIF for immunoglobulin replacement therapy in primary immunodeficiency diseases (PID).
Methods
Flebogamma® 5% DIF was administered at seven clinical sites to 46 subjects with well-defined primary immunodeficiency diseases at a dose of 300–600 mg/kg every 21–28 days for 12 months.
Results
The calculated serious bacterial infection rate was 0.021/subject/year. The incidence of adverse events considered potentially related to Flebogamma® 5% DIF during or within 72 h after completing an infusion was approximately 10%. The half-life in serum of the administered IgG was around 31 days.
Conclusions
Flebogamma® 5% DIF is efficacious and safe, has adequate pharmacokinetic properties, is well-tolerated and maintains the profile of Flebogamma® 5% for the treatment of primary humoral immunodeficiency diseases.
