          4. Subjects must have been treated with a stable dose of immune globulin administered
             intravenously (IGIV) or subcutaneously (IGSC) and has documented trough or steady
             state IgG levels of ≥ 5 mg/mL.

        Exclusion Criteria:

             cerebrovascular accident, pulmonary embolism, at any time.

          4. Subject has received blood products except IGIV, IGSC, or albumin within the previous
             12 months or has participated in another study (except for IGIV, IGSC studies) within
             the previous 4 weeks.

             subject is on continuous prophylactic antibiotics.

          7. Subject is positive for human immunodeficiency virus (HIV)-1 or HIV-2, a positive
             hepatitis C virus (HCV) or hepatitis B virus (HBV).

          8. Subject has levels of alanine aminotransferase (ALT) or aspartate aminotransferase
             (AST) >2.5 times the upper limit of normal (ULN).

          9. Subject has serum creatinine >1.5 times the ULN or a severe chronic condition such as
             renal failure with proteinuria.

         10. Subject has anemia with a hemoglobin level ≤8 g/dL.

         11. Subject has severe neutropenia with neutrophil count ≤1000 per mmᴧ3 or has lymphopenia
