Study of Immune Deficiency Patients Treated With Subcutaneous Immunoglobulin (IgPro20, Hizentra®) on Weekly and Biweekly Schedules

Summary

The purpose of the study is to assess the impact of immunoglobulin treatment by subcutaneous injections every 2 weeks (biweekly) on a cohort of patients with primary and secondary immune deficiencies. The full study will consist of safety, efficacy and Quality of Life (QoL) evaluations and a pharmacokinetic (PK) sub-study. The primary objectives of the study are to determine tolerability and safety of biweekly IgPro20 injection regimen and to compare PK outcomes on weekly and biweekly IgPro20 therapy. Patients who have received and/or are currently receiving immunoglobulin G (IgG) in intravenous (IVIg), or subcutaneous (SCIg) infusions are eligible for inclusion if they meet inclusion/exclusion criteria. The study consists of two parts. In Part 1 of the study enrolled subjects will receive IgPro20 weekly for either 12 weeks (for patients on SCIg infusion prior to the study) or 24 weeks (for patients on IVIg infusion prior to the study). Part 2 will consist of a biweekly treatment with IgPro20 for 52 weeks, for both groups. Additionally, study subjects meeting inclusion criteria for the PK sub-study will undergo a PK sample collection for 1 week and 2 weeks in study Parts 1 and 2, respectively.
