Effective Anthrax Cure In Experimental Drug Raxibacumab

An experimental drug called raxibacumab has been found to be effective in treating anthrax poisoning, say researchers.

Researchers have found that an experimental drug called raxibacumab has been found to be effective in treating anthrax poisoning.

"The results published today showed that a single dose of raxibacumab was highly effective as a treatment for inhalation anthrax in both rabbits and monkeys," said Dr Sally D. Bolmer, R.A.C, lead author and Senior Vice President, Development and Regulatory Affairs, HGS.

Anthrax - Bacillus - Symptoms - Diagnosis - Treatment - FAQs
Anthrax is caused by the bacterium Bacillus anthracis and spreads when the anthrax spores are inhaled, ingested, or come into contact with the skin lesion on a host.

"Raxibacumab acted quickly to provide a significant survival benefit to animals showing clinical signs of disease caused by exposure to a dose of aerosolized anthrax spores that was approximately 200 times the median lethal dose.

"We also note that the safety profile shown in healthy human volunteers provides support for use of raxibacumab in the clinical setting of immediately life-threatening inhalation anthrax disease," she added.

The drug works by targeting anthrax toxins after they are released by the bacteria into the blood and tissues.

Novel Handheld Device Detects Anthrax With Outstanding Accuracy
Veritide Ltd., confirm the exceptional accuracy of its Ceeker™ (pronounced seeker ) portable bacterial detection device in discriminating between anthrax and hoax substances.

In an inhalation anthrax attack, people may not know they are infected with anthrax until the toxins already are circulating in their blood, and it may be too late for antibiotics alone to be effective.

"We are very proud that the importance of these data and the rigor and high quality of our scientists' work have led to publication in The New England Journal of Medicine," said Dr David C. Stump, Executive Vice President, Research and Development, HGS. Based on these results, we believe raxibacumab has the potential to be a significant step forward in the treatment of inhalation anthrax," he added.
