General information about the trial
|
|||
Main objective of the trial |
To demonstrate the bioequivalence of Gammaplex® 10 (Gammaplex® [10%] 10 g in 100 mL) intravenous immunoglobulin (IGIV) and Gammaplex® 5% (Gammaplex® [5%] 5 g in 100 mL) IGIV with respect to area under the curve within a 28-day dosing interval (AUC0-28) in a cohort of adult subjects.
|
||
Protection of trial subjects |
The number of PK samples was the minimum number required to provide an evaluable PK profile.

Dosage and administration details |
All subjects were to receive a dose of 300 to 800 mg/kg/infusion. Subjects were to receive the same dose as per their prior IGIV.
Infusions were administered on either a 21-day or 28-day treatment schedule, depending on the subject's cycle of infusions during prior IGIV treatment. Subjects were randomised to receive either 5 infusions of Gammaplex 5% followed by 5 infusions of Gammaplex 10%, or 5 infusions of Gammaplex 10% followed by 5 infusions of Gammaplex 5%.
