The group hopes 95Mat5 might type the idea of the primary monoclonal antibody therapy used in opposition to snake bites. Because it could be based mostly on a human molecule, relatively than “foreign” horse antibodies, it also needs to be “safer than current antivenom”, mentioned Prof Casewell.
“Scalability is unlikely to be a major challenge once an appropriate manufacturing partnership is in place,” he added, although he famous that reaching the agricultural areas most in danger is prone to stay a “major hurdle”.
Still, whereas the identification of 95Mat5 and the success in mice is a significant second, it should take a while for a drug to be available.
“There remain considerable challenges,” mentioned Prof Casewell. “There are currently no monoclonal antibodies in clinical use for snakebite, so this would be several years away from implementation. We would need to assess safety and efficacy of the antibody in clinical trials first, before any approval for use in patients.
“Also, this antibody is only tackling one class of toxins – though this is an important class – so additional work needs to be done on discovering other antibodies or drugs that neutralise other types of toxins too.
“But if we can develop similar broadly inhibiting solutions for other toxin families … then in the long term we might be able to develop a combination therapy that does provide that global breadth,” Prof Casewell mentioned.
