Primary Outcome Measures
NameTimeMethod
Main Objective: Main objective of this phase IIIa/IV study is to demonstrate efficacy, safety, and pharmacokinetic properties of the new human normal intravenous immunoglobulin preparation Intratect®/BT681 in patients with primary immunodeficiency syndromes (PID) with hypo- or agammaglobulinemia. <br>So far, 17 PID patients had been treated in a clinical study with Intratect®/BT681 for a 6months period (Scheuplein et al, 2002). In the present study, 50 patients are planned to be enrolled for a treatment period of 48 weeks in order to achieve adequate statistical power and to exclude a bias on the efficacy data by seasonal influences, respectively.;Secondary Objective: Comparison of IgG trough levels to previous standard IVIG treatment;Primary end point(s): Number of acute serious bacterial infections per subject per year including bacterial pneumonia, bacteremia/sepsis, osteomyelitis/septic arthritis, visceral abscesses, and bacterial meningitis.
