What is the mechanism of action of this treatment?

The most common treatment for Primary Immune Deficiency (PID) is immunoglobulin replacement therapy, which includes subcutaneous human immunoglobulin (SCIG). SCIG provides necessary antibodies that PID patients lack, thereby enhancing their immune system's ability to fight infections. This therapy is crucial for PID patients as it helps prevent recurrent infections, reduces the severity of infections, and improves overall quality of life. By maintaining adequate antibody levels, SCIG minimizes the risk of complications associated with infections, which is vital for the health and well-being of individuals with PID.

What side effects are associated with this type of intervention?

Common side effects of subcutaneous human immunoglobulin (SCIG) treatments, such as those being studied in the trial for Newnorm, include local reactions at the injection site (e.g., redness, swelling, itching, and pain). Systemic side effects may include headaches, fatigue, fever, nausea, and muscle pain. These side effects are generally mild to moderate and often resolve on their own. Serious side effects are rare but can include severe allergic reactions and thrombotic events.

What prior FDA approvals exist?

FDA-approved treatments for Primary Immune Deficiency (PID) often involve immunoglobulin replacement therapy, which provides essential antibodies to prevent infections. Similar to the subcutaneous human immunoglobulin (Newnorm) being studied, other approved treatments include intravenous immunoglobulin (IVIG) and subcutaneous immunoglobulin (SCIG) products. These therapies, such as Hizentra, Gammagard, and Gamunex-C, are designed to boost the immune system by supplying the necessary antibodies that patients with PID lack, thereby reducing the frequency and severity of infections.

What other types of research exist?

Promising novel alternatives to Subcutaneous Human Immunoglobulin (Newnorm) for primary immunodeficiency patients include monoclonal antibodies such as omalizumab, which has shown efficacy in increasing the threshold for food allergens and may have broader immunomodulatory effects. Additionally, RNA interference therapies like vutrisiran, which have been effective in other conditions like amyloidosis, could potentially be repurposed for primary immunodeficiency. These alternatives are still under investigation, and their use should be discussed with a healthcare provider.

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

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.

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.

Must not have

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).

Severe liver dysfunction (alanine aminotransferase [ALT] >3 times the upper limit of normal for the expected normal range for the testing laboratory) at screening.

Summary

This trial is testing a new antibody treatment called Newnorm, which is given through an injection under the skin. It aims to help people with primary immunodeficiency diseases, whose immune systems are weak. The treatment provides extra antibodies to help their bodies fight infections.

Who is the study for?

This trial is for people aged 2 to 75 with Primary Immunodeficiency Diseases (PID) who need immunoglobulin therapy. They must have been on stable treatment doses for at least 12 weeks and agree to protocol requirements, including blood sampling. Excluded are those with severe allergies to IgA, obesity (BMI >40), liver dysfunction, uncontrolled diabetes or hypertension, certain heart conditions, recent blood product exposure other than IgG for PID, or active infections.

What is being tested?

The study is testing 'Newnorm,' a subcutaneous human immunoglobulin treatment for patients with PID. It's an open-label Phase 3 trial assessing how the body processes the drug and its effectiveness and safety across multiple centers.

What are the potential side effects?

While specific side effects of Newnorm aren't listed here, typical reactions to immunoglobulin treatments can include injection site discomfort, headache, fatigue, nausea or vomiting. Severe allergic reactions are rare but possible.
