Safety and Pharmacokinetics Study 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).

Primary outcomes

  1. Number of Participants Reporting Adverse Events (AEs)

    Time frame: From the time of infusion through Day 90.

    Any untoward medical occurrence reported to or observed by the principal investigator (PI), including as identified from other safety assessments (eg, vital signs, clinical laboratory testing, electrocardiogram).

Secondary outcomes

  1. Maximum Plasma Titer/Concentration of TNA (Toxin Neutralizing Antibody) (Cmax)

    Time frame: From the time of infusion through Day 90 postinfusion.

    Blood samples for TNA analysis collected at pre-infusion; 5 minutes postinfusion; 8, 24, and 48 hours postinfusion; and Days 3, 5, 10, 14, 21, 30, 45, 60, and 90 postinfusion. Assay results are reported as the 50% neutralization factor, TNA NF50: the ED50 of the test sample (ie, effective dilution of test sample that neutralized 50% of toxin) divided by the ED50 of the reference standard.

    Time frame: From the time of infusion through Day 90 postinfusion.

    Blood samples for TNA analysis collected at pre-infusion; 5 minutes postinfusion; 8, 24, and 48 hours postinfusion; and Days 3, 5, 10, 14, 21, 30, 45, 60, and 90 postinfusion.

  4. Area Under the Curve to Infinity (AUC[0-inf])

    Time frame: From the time of infusion through Day 90 postinfusion.

  5. Elimination Rate Constant

    Time frame: From the time of infusion through Day 90 postinfusion.

    Blood samples for TNA analysis collected at pre-infusion; 5 minutes postinfusion; 8, 24, and 48 hours postinfusion; and Days 3, 5, 10, 14, 21, 30, 45, 60, and 90 postinfusion.

  6. Elimination Half-life (t½)

    Time frame: From the time of infusion through Day 90 postinfusion.

    Blood samples for TNA analysis collected at pre-infusion; 5 minutes postinfusion; 8, 24, and 48 hours postinfusion; and Days 3, 5, 10, 14, 21, 30, 45, 60, and 90 postinfusion.

  7. Mean Residence Time (MRT)

    Time frame: From the time of infusion through Day 90 postinfusion.

    Blood samples for TNA analysis collected at pre-infusion; 5 minutes postinfusion; 8, 24, and 48 hours postinfusion; and Days 3, 5, 10, 14, 21, 30, 45, 60, and 90 postinfusion.
