Study Summary

This trial aims to investigate the use of spirometry to determine if immunodeficiency patients on gammaglobulin replacement therapy could benefit from an increase in their treatment. The study will involve 22

Who is the study for?
This trial is for people with Common Variable Immunodeficiency (CVID) who've been on stable immunoglobulin replacement therapy (IGRT) for at least 3 months. They should have specific lung function test results showing mild to moderate obstruction. Preference is given to those already using Hizentra.Check my eligibility
What is being tested?
The study tests if using spirometry, a lung function test, can help adjust the dose of IGRT in CVID patients with airway disease. Half will continue their current IGRT dose; the other half will receive an increased dose of Hizentra for six months.See study design
What are the potential side effects?
Potential side effects from increasing Hizentra dosage could include headache, nausea, fatigue, injection site reactions or infections due to changes in immune system activity.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Treatment GroupExperimental Treatment1 Intervention
11 subjects will have their level of immunoglobulin replacement therapy increased by the equivalent of 0.05 gm/kg in dose per 4 weeks, adjusted for bioavailability as per manufacturer's instructions. On average, rounded up to the nearest gram, this will typically increase their dose of Hizentra by 2 gm per week.
Group II: Control GroupActive Control1 Intervention
11 subjects will be treated for 6 months at their current dose of Hizentra
