Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate safety and clinical benefit of AIGIV used for treatment of patients with inhalational anthrax. This study will be implemented only in the event of a major anthrax exposure event. The study is designed to collect information on safety, clinical benefit (such as extent of anthrax illness and survival) and serum concentrations of AIGIV (for AIGIV pharmacokinetics) and anthrax toxins from inhalational anthrax patients treated with AIGIV.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a post-marketing requirement from the FDA to evaluate safety and clinical benefit of AIGIV administered to patients as part of their medical care after inhalational exposure to Bacillus anthracis. Study information (i.e. data on safety and clinical benefit evaluation of AIGIV up to Day 30 following administration) and patient samples (for assessment of AIGIV pharmacokinetics and anthrax toxin levels) will be collected (up to Day 7 following AIGIV administration) prospectively to the extent possible; however, due to logistical complexities that will likely occur during a mass anthrax exposure event, most data for this study will be collected retrospectively (including scavenged patient samples for assessment of serum AIGIV concentration and anthrax toxin levels). Therefore, both prospective and retrospective data collection are allowed in this study to maximize the amount of information obtained from inhalational anthrax patients who have been administered AIGIV.
