China Medical System Holdings Limited has secured exclusive commercialization rights for two innovative monoclonal antibody therapies, Vecantoxatug for tetanus prevention and Silevimig for rabies prevention, through collaboration agreements with Genrix Bio.
Vecantoxatug, which received Breakthrough Therapy designation from China's NMPA in May 2024, demonstrated superior protection compared to human tetanus immunoglobulin in Phase III trials and has its New Drug Application under review.
Silevimig represents the world's first recombinant, fully human bispecific antibody for rabies prevention, designed according to WHO recommendations and showing non-inferior efficacy to current treatments in Phase III trials.
Both therapies address significant unmet medical needs in China, where tetanus has a 30-50% mortality rate and only 15% of high-risk rabies exposure cases receive passive immunization despite 16 million annual Category III exposures.
