This is a Phase 3, multicenter, open-label study of safety, tolerability, efficacy, and pharmacokinetics (PK) of ProMetic's Immune Globulin Intravenous (Human) 10% (Prometic IGIV 10%, the investigational medicinal product [IMP]), in Adults and Children with Primary Immunodeficiency Diseases (PIDD).

Official Title

A Phase 3, Multinational, Multicenter, Open-Label Study of the Safety, Tolerability, Efficacy, and PK of ProMetic BioTherapeutics Immune Globulin Intravenous (Human) 10% in Adults and Children With Primary Immunodeficiency Diseases


This is a pivotal Phase 3, open-label, single-arm, multicenter study to assess the tolerability, safety, efficacy, and PK of the IMP in adults and children with PIDD. A total of approximately 75 subjects aged 2-80 years will be enrolled in the study. Subjects who switch from an investigational immune globulin or subcutaneous immune globulin (IGSC) are required to receive a stable dose of commercial product (CP), which is a licensed commercially available immune globulin intravenous (IGIV) product for at least 3 cycles before they can be given the IMP. This study schema will result in the CP Treatment Period and IMP Treatment Period. All subjects will be treated on an outpatient basis with the IMP for approximately 1 year, with the dose and schedule based on their previous IGIV treatment regimen (21-day or 28-day dosing interval). A subset of subjects will participate in a PK sub-study.

The primary objective of the study is to examine the rate of clinically documented serious bacterial infections (SBIs) in subjects treated with the IMP to achieve a rate of less than one SBI per year.
