The Company recently announced the publication of key results with BT-VACC™ showing that mucosal immunization with a multivalent version of the vaccine induces a robust immune response that resulted in protection against several of the natural serotypes of botulinum toxin. BT-VACC™ is composed of a component of what is known as the heavy chain of each of the A, B, and E serotypes of botulinum toxin. The heavy chain component lacks the region of the toxin that is responsible for blocking neurotransmitter functions. The subunits can bind avidly to receptors on the surface of mucosal cells and traverse lung and gastrointestinal tissue to stimulate immunity. Because the binding subunits do not contain the toxic part of the molecule, the vaccine is safe and stimulates antibodies in not only the blood but those antibodies that coat mucosal surfaces. It is thought that antibodies that are present in lung and gastrointestinal secretions will block the uptake of the toxin before entering the bloodstream and reaching peripheral nerves.

About Botulinum Toxin

Botulinum toxin is an extremely potent neurotoxin of bacterial origin that inhibits peripheral nerve function, causing severe and often fatal descending flaccid muscle paralysis. Natural botulism resulting from ingestion of toxin from contaminated food is very rare, but artificially, botulism also can result from bioterrorism and biowarfare. Because extremely small amounts of the toxin can cause neurological effects, it is classified as a category A Biothreat by the CDC. The toxin can enter the body very efficiently through lung tissue and through the gastrointestinal tract, making the threat of purposeful food contamination with botulinum toxin a real possibility as a biological weapon. Because the toxin rapidly enters target neural cells, exposure is difficult to treat with any available therapeutic regimen other than supportive care
