About ETI-204

ETI-204 is a high-affinity, humanized and deimmunized monoclonal antibody that targets the protective antigen of B. anthracis and neutralizes the lethal effects of anthrax toxins by binding to Protective Antigen. It is an investigational agent being developed for treatment of inhalational anthrax. ETI-204 is formulated as a solution and is being evaluated for intravenous (IV) and/or intramuscular (IM) administration. ETI-204 efficacy and safety is being studied in animal models of inhalational anthrax and safety studies are being conducted with human volunteers. Three studies assessing pharmacokinetics and safety of intravenous (IV) administration of ETI-204 in humans have been completed. The more common adverse events related to ETI-204 administration across the three studies included upper respiratory tract infection, nausea, headache, nasal congestion and erythema. ETI-204 was granted Fast Track status and Orphan Drug Designation by the FDA.
