Mechanism of action of Raxibacumab[edit source]
Obiltoxaximab (oh" bil tox ax i mab) is a human-mouse chimeric monoclonal antibody to the Bacillus anthrax protective antigen that is the major immunogenic antigen produced by the bacterial infection. The binding of obiltoxaximab to the anthrax protective antigen blocks the binding of the bacterial toxin to host cells. In several animal models of inhalation anthrax, obiltoxaximab ameliorated the course of the disease and, if given before the onset of signs and symptoms, prevented clinically apparent disease.
FDA approval information for Raxibacumab[edit source]
Obiltoxaximab was approved for use in the United States in 2016 for the prevention and treatment of inhalation anthrax. The approval was based upon the efficacy of obiltoxaximab in animal models of anthrax and on data on safety and pharmacokinetics in healthy human volunteers. Human anthrax is exceedingly rare, but has occurred in the United States as a result of acts of bioterrorism.
