Not conducted (not applicable to a monoclonal antibody)
“Genetic toxicity studies were not applicable for this therapeutic biologic monoclonal antibody.”

Carcinogenicity
Not conducted: rodent study not feasible due to species specificity; ECAC concurred
“Based on species specificity, a rodent carcinogenicity study with sarilumab was not considered feasible. The Executive Carcinogenicity Assessment Committee (ECAC) concurred that a carcinogenicity study was not feasible.”

“There were no observed effects on fertility in mice. In an expanded prenatal and postnatal development study in monkeys, no effects on evaluated parameters in neonates were observed. The NOAEL was the high dose of 50 mg/kg/week.”

Carcinogenicity model
Not conducted: rodent study not feasible (species specificity); weight-of-evidence risk assessment instead

Carcinogenicity timing
Not required; ECAC concurred no study feasible
“The Executive Carcinogenicity Assessment Committee (ECAC) concurred that a carcinogenicity study was not feasible. No nonclinical studies were required to evaluate the potential carcinogenicity of sarilumab.”
