Raxibacumab- Approved for the treatment of inhalational Anthrax

        Kesimpulan Laporan Penelitian Obat ABthrax atau Raxibacumab Mencegah Racun Bakteri Antraks 
         The U.S FDA today approved raxibacumab a monoclonal antibody in the prophylaxis and treatment of inhalational anthrax. Anthrax is a disease caused by Bacillus anthracis bacteria.Inhalational form is also known as wool sorter’s disease as workers in wool industry inhale the spores of bacillus anthracis while sorting out the wool.Anthrax has also been tried to use as a weapon of bioterrorism.
         Raxibacumab is a chimeric monoclonal antibody targeting the protective antigen (PA) component of the lethal toxin of Bacillus anthracis. In case of bioterrorism by the use of anthrax spores, raxibacumab is available along with the antibiotics.
                   More animals treated with raxibacumab lived compared to animals treated with placebo. Sixty-four percent of animals in the monkey study and 44 percent of animals in one rabbit study receiving the 40 milligrams per kilogram dose of raxibacumab survived exposure to anthrax, compared with none in the placebo groups. All surviving animals developed toxin-neutralizing antibodies. Another study in rabbits showed that 82 percent of animals treated with antibiotics and raxibacumab survived exposure to anthrax compared with 65 percent of animals receiving antibiotic treatment alone.
             The safety of raxibacumab was evaluated in 326 healthy human volunteers. Common side effects included rash, extremity pain, itching and drowsiness.
        Raxibacumab was developed by Rockville, Md.-based Human Genome Sciences, in conjunction with the U.S. Department of Health and Human Services’ Biomedical Advanced Research and Development Authority. Human Genome Sciences has since been acquired by GlaxoSmithKline.
