Dosage and administration details |
Commercially available Hizentra was used for this study at doses that were consistent with the approved weekly and biweekly Hizentra therapy regimens for patients with immune deficiency. In Part 1, all subjects were observed for 12 weeks on a weekly Hizentra home infusion treatment regimen. In Part 2, subjects were observed for up to 52 weeks on a biweekly Hizentra home infusion treatment regimen. Part 2 of the study began immediately after the end of Part 1, with the first biweekly Hizentra infusion occurring 2 weeks after the last weekly infusion of Hizentra.
