Condition(s) targeted: Anthrax

Intervention: Anthrax Immune Globulin Intravenous (AIGIV) (Biological); Gamunex (Biological)

Phase: Phase 1/Phase 2

Status: Completed

Sponsored by: Emergent BioSolutions

Official(s) and/or principal investigator(s):
Mohamed Al-Ibrahim, MD, Principal Investigator, Affiliation: SNBL Clinical Pharmacology Center Inc, Baltimore, MD
Robert J Hopkins, MD, MPH & TM, Study Director, Affiliation: Emergent Product Development Gaithersburg


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(R)(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).
