Moreover, HK013-G1 is well tolerated in cynomolgus monkeys. These results show that this bsAb has the potential to develop into a new clinical therapy for cancer types with high-level MSLN expression.

Compared with anti-4-1BB parent antibody and urelumab, HK013 induced weaker FcγR-mediated 4-1BB activation. Conclusions IgG1-based HK013-1 prevents tumor development by directly killing tumor cells and depleting Treg to relieve immunosuppression. Preclinical studies have shown that IgG1-based HK013-1 has good antitumor activity and safety, which may further develop its clinical potential.
