Rapid Infusion of Immune Globulin Intravenous (Human) In Primary Immunodeficiency Patients

Overview

The objective of this study is to determine if the safety and tolerability of Immune Globulin Intravenous (Human), 10% caprylate/chromatography (IGIV-C)purified is similar when infused at two different infusion rates. The primary objective is to compare the incidence and severity of all infusion related adverse events when IGIV-C, 10% is administered at a rate of 0.14 mL/kg/min compared to a rate of 0.08 mL/kg/min after a single daily infusion.

This is a prospective, single blind, randomized, multi-center cross-over trial in patients with Primary Immune Deficiency. Patients with a confirmed diagnosis of primary Immune Deficiency will be treated with two daily infusions given 3-4 weeks apart at the fixed individual IGIV dose regimen (400-600 mg/kg) established prior to entry into the study. Any subject with an established dose in the range of 200-399 mg/kg will be assigned to receive 400 mg/kg during the course of the study during the same dosing schedule established prior to entry into the study. After a screening period lasting not more than four weeks, patients will be randomized into one of two cross-over groups. Patients randomized to Group 1 will receive their first IGIV-C, 10% dose at a rate of 0.08 mL/kg/min and their second infusion at a rate of 0.14 mL/kg/min, whereas patients randomized to Group 2 will receive IGIV-C, 10% at a rate of 0.14 mL/kg/min on the first infusion day and then 0.08 mL/kg/min on the second infusion day. All patients just prior to each IGIV-C, 10% infusion will receive the same volume of 5% dextrose as calculated for their IGIV-C, 10% infusion and given at a target rate according to the schema below. Group 1: * Infusion #1 (Week 0)Dextrose (0.14 mL/kg/min), then IGIV-C, 10% (0.08 mL/kg/min) * Infusion #2 (Week 3-4)Dextrose (0.08 mL/kg/min), then IGIV-C, 10% (0.14 mL/kg/min) Group 2: * Infusion #1 (Week 0)Dextrose (0.08 mL/kg/min), then IGIV-C, 10% (0.14 mL/kg/min) * Infusion #2 Dextrose (0.14 mL/kg/min), then IGIV-C, 10% (0.08 mL/kg/min)
