“No genotoxicity testing was conducted. Toripalimab is a large protein molecule and per ICH S6(R1), the range and type of genotoxicity studies “are not applicable to biotechnology-derived pharmaceuticals and therefore are not needed.””

Carcinogenicity
Not conducted (ICH S6(R1), ICH S9 advanced cancer)
“No carcinogenicity studies were conducted. In accordance with ICH S6(R1) “Standard carcinogenicity bioassays are generally inappropriate for biotechnology-derived pharmaceuticals””

Reproductive & developmental
No dedicated studies; weight-of-evidence literature assessment; no adverse effects on reproductive organs in 4- and 26-week monkey studies
“In the pivotal 4-week and 26-week GLP-compliant toxicity studies, evaluation of sexually mature male and female cynomolgus monkey reproductive tissues (organ weights, macroscopic and microscopic examination) did not reveal any adverse effects of toripalimab on reproductive organs.”

Safety pharmacology
Incorporated into repeat-dose monkey studies; no cardiovascular, respiratory or CNS effects up to 100 mg/kg
“The FDA agrees that there were no adverse effects of toripalimab at doses up to 100 mg/kg given once weekly for 4 weeks on cardiovascular, respiration, and central nervous system parameters in male and female cynomolgus monkeys.”
