Brief description of study

An Open-label Multicenter Study to Evaluate the Safety and Tolerability of Higher Infusion Parameters of Immune Globulin Subcutaneous (Human), 20% Liquid (Hizentra®) in Subjects With Primary Immunodeficiency

Detailed Study Description

This multicenter, open-label, parallel-arm, non-randomized study is designed to evaluate safety and tolerability of higher infusion parameters of IgPro20 in subjects with primary immunodeficiency (PID). A total of 45 subjects (including at least 14 [30%] pediatric subjects = 17 years of age and at least 9 [20%] obese subjects with body mass index [BMI] of =30 kg/m2) with confirmed PID will be evaluated in the study. The study will include three cohorts of 15 subjects each as follows: i) Pump-Assisted Volume Cohort (weekly infusions), volume per injection site of 25 mL up to 50 mL, ii) Pump Assisted Flow Rate Cohort (weekly infusions), flow rate per injection site of 25 mL/hour up to 100 mL/hour, iii) Manual Push Flow Rate Cohort (2 to 7 infusions per week), flow rate per injection site of 25 to 30 mL/hour up to 120 mL/hour (equivalent of approximately 0.5 mL/minute up to 2 mL/minute). Each cohort will test 3 infusion parameter levels (4 for the pump-assisted flow rate cohort), repeated at least 4 times over a duration of 12 weeks (16 weeks for the flow rate cohort). After 4 infusion weeks at each level, qualifying subjects (responders) will switch to the next infusion parameter level (eg, from 25 to 50 mL/h). During the study, the weekly dose will remain unchanged (as prescribed by treating physician, usually within 100-200 mg/kg per week range); only the respective infusion parameter under evaluation will change.
