Ended Therapeutic confirmatory (Phase III) Human Normal Immunoglobulin

Prospective, open-label, single-arm, multicentre Phase 3 study to evaluate the pharmacokinetics, efficacy, tolerability, and safety of subcutaneous human immunoglobulin (Newnorm) in patients with primary immunodeficiency diseases

EU CTIS ID: 2024-511231-94-00

What this study is testing

Primary Objective: The primary efficacy objective of this study is to assess the efficacy of Newnorm in preventing serious bacterial infections (SBIs). The primary pharmacokinetic (PK) objective is to confirm that weekly subcutaneous (SC) dosing of Newnorm—adjusted by a dose conversion factor (DCF) of 1.37 for patients previously treated with an intravenous immunoglobulin (IVIG) product—results in average total immunoglobulin G (IgG) levels that are statistically non-inferior to 3- or 4-weekly IVIG dosing.

Who can take part

You may be able to join if

1. Age of ≥2 years and ≤75 years
2. 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.
3. 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.
4. 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.
5. 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.
6. Willingness to comply with all aspects of the protocol, including blood sampling, for the duration of the study.

You likely can't join if

1. 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.
10. Moderate to severe renal dysfunction (per investigator discretion based on estimated glomerular filtration rate [eGFR] ≤44 mL/min/1.73 m2, as defined by KDIGO Clinical Practice Guideline) or predisposition to acute renal failure (e.g., any degree of pre-existing renal dysfunction in presence of additional acute renal failure risk factors, e.g. routine treatment with known nephrotoxic drugs).
11. Uncontrolled diabetes mellitus (HbA1c > 7% / >53 mmol/mol).
12. Uncontrolled arterial hypertension (systolic blood pressure of ≥ 130 mmHg for the subject under 13 years of age, ≥ 140 mmHg for subject 13 to 17 years of age, and > 160 mmHg for adults).
13. Dysrhythmia/Tachycardia (resting heart rate > 100 bpm for adults/adolescents and > 120 bpm for children) and symptomatic bradycardia (resting heart rate < 60 bpm for adults, < 50 bpm for adolescents, and < 75 bpm for children in presence of symptoms e.g., low blood pressure, abnormal rhythm, chest discomfort, shortness of breath). Physiological sinus bradycardia in physically active adults/children/athletes is NOT an exclusion criterion).
14. The subject has a history of or current diagnosis of deep venous thrombosis or thromboembolism (e.g. myocardial infarction, cerebrovascular accident, or transient ischemic attack); history refers to an incident in the year prior to screening or 2 episodes over lifetime.
