Inclusion criteria
. Age of ≥2 years and ≤75 years
. Documented and confirmed diagnosis of PID as defined by European Society of Immunodeficiencies (ESID) and the Pan American Group for Immune Deficiency (PAGID) and requiring immunoglobulin replacement therapy due to hypogammaglobulinaemia or agammaglobulinaemia. The exact type of PID must be recorded.
. At least 12 weeks of regular treatment before the screening visit (i.e., with a stable dosing interval) with any IVIG, SCIG, or fSCIG, with a stable IgG dose between 200 and 800 mg/kg/month. A stable dose is defined as one that deviates less than ±25% from the mean dose for all infusions within this 12-week period before screening.
. Trough level of IgG ≥5 g/L at screening and documentation of an IgG trough level of ≥5 g/L at least once within the previous 12 weeks.
. Freely given written informed consent from adult patients or freely given written informed consent from the patient's parent(s)/legal guardian(s) and written informed assent from paediatric or adolescent patients in accordance with the applicable regulatory requirements, before any study-specific procedure takes place.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Willingness to comply with all aspects of the protocol, including blood sampling, for the duration of the study.
Exclusion criteria
. Any acute infection requiring IV antibiotic treatment within 2 weeks before the screening visit or during the screening period, or any SBI within the 3 months prior to the screening visit or during the screening period.
. The patient has isolated specific antibody deficiency disorder, isolated IgG subclass deficiency, or transient hypogammaglobulinaemia of infancy.
. Current medical condition or history of condition known to cause secondary immune deficiency, for example, chronic lymphocytic leukaemia, lymphoma, multiple myeloma, or chronic or recurrent neutropenia (absolute neutrophil count \<1000/μL).
. Known history of ADRs to IgA contained in other products.
. Body mass index \>40 kg/m2.
. Exposure to blood or any blood product or plasma derivative other than IgG for PID within 3 months before the first infusion of Newnorm.
. History of or ongoing severe hypersensitivity, e.g., anaphylaxis or severe systemic response, or persistent reactions to blood or plasma-derived products, or to any component of Newnorm (such as glycine).
. Severe liver dysfunction (alanine aminotransferase \[ALT\] \>3 times the upper limit of normal for the expected normal range for the testing laboratory) at screening.
