Reproductive & developmental
No dedicated studies; literature on EGFR knockouts and cetuximab monkey data (embryolethality, abortions at 1.6-4x human dose) support fetal-harm warning
“Cetuximab was detected in amniotic fluid and the serum of embryos from treated dams and caused embryolethality and abortions at doses of 1.6 to 4 times the recommended human dose.”

Safety pharmacology
No dedicated studies; ECG, heart rate, blood pressure and respiratory rate in 26-week monkey study: no findings
“No dedicated safety pharmacology studies were provided. The safety pharmacology endpoints were evaluated in the 26-week repeat-dose toxicology study (i.v).”
“Consistent with the ICH S6 guidance, genetic toxicology studies were not conducted or required for necitumumab.”

Carcinogenicity model
Not conducted; not warranted for advanced cancer (ICH S9), no concern from structure or mechanism
“Carcinogenicity studies are not warranted to support marketing for therapeutics intended to treat patients with advanced cancer (ICH S9 [ICH 2009]) and there is no cause for concern (ICH S1A) based on the structure or mechanism of action of necitumumab.”
Not required for a product to treat advanced cancer

hERG / QT
No hERG assay; no effects on heart rate, blood pressure or ECGs in 26-week monkey study
“There were no treatment-related effects on body weight, food consumption, ophthalmoscopy, heart rate, blood pressure, respiratory rate, electrocardiograms (ECGs), coagulation, urinalysis, or organ weight at any dose level.”
