Official title
A Multi-center, Single-Sequence, Open-label Study to Evaluate IGSC 20% Biweekly Dosing in Treatment-Experienced Subjects and Loading/Maintenance Dosing in Treatment-Naïve Subjects With Primary Immunodeficiency
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the study is to determine whether biweekly (every 2 weeks) administration of Immune Globulin Subcutaneous (Human), 20% Caprylate/Chromatography Purified (IGSC 20%) produces a steady-state area under the concentration versus time curve (AUC) of total Immunoglobulin G (IgG) that is non-inferior to that produced by weekly administration of IGSC 20% in treatment-experienced participants with primary immunodeficiency (PI).
