Safety margin at NOAEL
Monkey embryo-fetal/perinatal study: no fetal harm at up to 373x MRHD exposure (AUC)
“In an embryo-fetal perinatal development study, pregnant cynomolgus monkeys received adalimumab from gestation days 20 to 97 at doses that produced exposures up to 373 times that achieved with the MRHD without methotrexate (on an AUC basis with maternal IV doses up to 100 mg/kg/week).”

NOAEL / key findings
39-week monkey NOAEL 32 mg/kg; thymus and spleen immune effects, mostly reversible over 20-week recovery
“In the 39 weeks study, most of these changes were reversible within the 20-week recovery period. In this study, the NOAEL was 32 mg/kg, with an AUC of 304 800 µg*h/ml.”
