Safety and Tolerability of Higher Infusion Parameters of IgPro20 (Hizentra) in Subjects With Primary Immunodeficiency (PID)

Completed · Phase 4

Conditions studied: Primary Immunodeficiency

In brief

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.

Who can join

Age: 2 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female on stable dose of IgPro20 (Hizentra) therapy.
• Women of childbearing potential must be using and agree to continue using medically approved contraception (which must be discussed with the study doctor) and must have a negative pregnancy test at screening.
• Subjects with PID, eg, with a diagnosis of common variable immunodeficiency or X-linked agammaglobulinemia, as defined by the Pan American Group for Immune Deficiency and the European Society of Immune Deficiencies.
• With infusion parameters as specified below:
• Pump-Assisted Flow Rate Cohort subjects only
• Experience with pump-assisted infusions of IgPro20 at the tolerated flow rate of 25 mL/h per injection site for at least 1 month prior to Day 1.
• Pump-Assisted Volume Cohort subjects only
• Total weekly IgPro20 dose of ≥ 50 mL (≥ 10 g).
• Experience with pump-assisted infusions of IgPro20 at tolerated volumes of 25 mL/injection site for at least 1 month prior to Day 1.
• Manual Push Flow Rate Cohort subjects only
• Experience with frequent (2-7 times per week) infusions of IgPro20 at the tolerated flow rate of approximately 0.5 mL/min (equivalent of 25-30 mL/h) per injection site for at least 1 month prior to Day 1. The dose (volume) per injection site should not exceed 25 mL.

You may not qualify if…

• Ongoing serious bacterial infections at the time of screening.
• Other significant medical conditions that could increase the risk to the subject.
• Females who are pregnant, breast feeding, or planning a pregnancy during the course study.
• Participation in a study with an Investigational Medicinal Product (IMP) other than IgPro20 within three months prior to enrollment.
