Safety and Pharmacokinetics Study of Anthrax Immune Globulin Intravenous (AIGIV)
March 14, 2024 updated by: Emergent BioSolutions
A Randomized, Double-Blind, Dose-Escalation Study Evaluating Pharmacokinetics and Safety of Anthrax Immune Globulin Intravenous (AIGIV)
The purpose of this study is to:
- evaluate the safety profile of a single intravenous administration of AIGIV (containing either 3.5 mg/kg, 7.0 mg/kg or 14.0 mg/kg anti-PA IgG) as compared with either 90 mg/kg, 180 mg/kg or 360 mg/kg total IgG, GAMUNEX® (immune globulin intravenous (human) 10% caprylate/chromatography purified). GAMUNEX is a trademark of Talecris Biotherapeutics.
- evaluate the pharmacokinetic (PK) profile of a single intravenous administration of AIGIV (containing either 3.5 mg/kg, 7.0 mg/kg or 14.0 mg/kg anti-PA IgG) as measured by lethal toxin neutralizing antibody (TNA).
