研究概览
简要总结
The purpose of the study is to determine the feasibility of infusing a full 4-week dose of Immune Globulin Intravenous (Human), 10% in a single subcutaneous site and the amount of recombinant human hyaluronidase needed to infuse that dose with no more than mild local adverse drug reactions.

入选标准
- •Written informed consent from either the subject or the subject's legally acceptable representative
- •Diagnosis of a PID disorder as defined by World Health Organization criteria1 for which the subject had been receiving a regimen of weekly or biweekly (every-other-week) subcutaneous IgG infusions or IGIV infusions every 21 to 28 days over a period of at least 8 weeks pre-study at an equivalent of a 4-week dose of 300 to 800 mg/kg bodyweight
- •Adults/adolescents aged 16 years and older)
- •For female subjects of child-bearing age: negative urine pregnancy test result at study entry and agreement to employ adequate birth control measures for the duration of the study
排除标准
- •Subjects positive at enrollment for one or more of the following: HBsAg, PCR for HCV, PCR for HIV Type 1
- •Subjects with levels of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 2.5 times the upper limit of normal for the testing laboratory
