AntoXa Corporation has obtained a license from Defence Research & Development Canada (DRDC), an Agency of the Canadian Department of National Defence, to develop and produce an anti-ricin monoclonal antibody for sale in markets worldwide.
The licensing agreement follows work AntoXa and the J.C. Hall laboratory at the University of Guelph conducted with DRDC to develop and produce the plant-made antibody PhD9 as a medical countermeasure for ricin exposure, a program that has received more than $600,000 (CAD) from the Government of Canada since 2014.
The PhD9 antibody drug candidate prevents ricin from penetrating cells. DRDC conducted in vitro and in vivo studies that found the plant-made version of the antibody showed therapeutic efficacy against ricin intoxication.
“We anticipate market entry for the PhD9 anti-ricin antibody within two to three years, a timeline that is dependent on raising the necessary funds for scale up and other activities necessary to obtain regulatory approvals,” said Ashley Meyers, AntoXa Chief Technical Officer.
Next steps for the commercialization of PhD9 are transitioning to large-scale GMP manufacturing, product characterization, animal safety and efficacy studies, and a Phase 1 human clinical trial. Medical countermeasures do not require Phase 2 and Phase 3 human efficacy trials for ethical reasons, therefore the path to regulatory approval is shorter than for other pharmaceuticals.
