Carcinogenicity
Not conducted; carcinogenic potential unknown; hematopoietic neoplasms in one high-dose female in 26-week surrogate mouse study
“The carcinogenic potential of ALXN1210 in animals is unknown. However, in the 26‐week repeat dose toxicology study in mice with BB5.1, multiple hematopoietic neoplasms (lymphoma/lung/salivary glands/thymus) occurred in 1 high dose female (60 mg/kg/week)”

Reproductive & developmental
Surrogate mouse studies: no fertility effects; EFD retinal dysplasia (2) and umbilical hernia (1) among 230 offspring at high dose
“When animal exposure to the antibody occurred in the time period from before mating until early gestation, no decrease in fertility or reproductive performance was observed. When maternal exposure to the antibody occurred during organogenesis, 2 cases of retinal dysplasia and 1 case of umbilical hernia were observed among 230 offspring”

Carcinogenicity timing
Not required: not generally relevant to biotechnology products (ICH S6(R1))
“No carcinogenicity studies were performed. The ICH S6 (R1) guideline indicates that nonclinical carcinogenicity studies are not generally considered relevant to biotechnology products.”
