“Genotoxicity studies have not been conducted with nirsevimab. In accordance with ICH S6(R1), genotoxicity studies are not required for biologics as they are not anticipated to interact with DNA or other genetic material.”
Not conducted; weight-of-evidence assessment revealed no specific carcinogenic risk
“Carcinogenicity studies have not been conducted with nirsevimab. A weight of evidence approach was conducted in accordance with the FDA’s recommendations and applicable ICH guidelines for establishing the carcinogenic potential of nirsevimab and did not reveal any specific carcinogenic risk.”

Not conducted (ICH S6(R1)): exogenous viral target, infant population; no reproductive tissue effects or placental binding
“In accordance with ICH guideline S6(R1), no dedicated studies have been conducted to evaluate the effects of nirsevimab on fertility, embryo-foetal, and prenatal and postnatal development.”
Incorporated into 4-week monkey study: no ECG, CNS or respiratory effects
“Safety pharmacology of nirsevimab was assessed as a component of the GLP 4-week repeat dose toxicology study in cynomolgus monkeys (Study #1468-038).”

No hERG assay; no adverse ECG effects in monkeys at 50 or 300 mg/kg IV or 300 mg IM weekly
“In that study, ECG parameters assessed predose and 24 hours postdose on Days 1 and 29 and prior to the recovery necropsy, showed no adverse nirsevimab-related effects following 50 mg/kg IV, 300 mg/kg IV, or 300 mg IM once weekly for five total doses.”
