"These data demonstrate the considerable activity obtained with intramuscular (IM) administration of the anti-toxin when given either before or after challenge in animal models of inhalational anthrax. We are extremely pleased that a single dose of ETI-204 demonstrated protection against inhalational anthrax infection," said Leslie Casey, PhD, Vice President, Research. "We look forward, in the very near term, to initiating a clinical study in healthy subjects to assess the pharmacokinetics and tolerability of IM administration in humans."
Anthrax is a life-threatening infectious disease caused by the bacterium Bacillus anthracis and remains one of the nation's top biowarfare threats. Much of the morbidity and mortality of anthrax can be attributed to anthrax toxins. Inhaled anthrax is often fatal, despite treatment with antibiotics. In the 2001 anthrax letter attacks, inhalational anthrax had a fatality rate of approximately 50% in humans infected, even when victims were given antibiotics and supportive hospital care.
ETI-204 is the only anthrax anti-toxin in advanced stages of development that is formulated as a solution and is being investigated for both IV and IM administration. A product that can be given IM as well as IV is highly desirable because it could provide the capability to more rapidly administer product to people outside of a hospital setting or where IV administration is not feasible.
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 deve
