Bimzelx: what safety margin did regulators accept?

bimekizumab · IL-17A/IL-17F
Check my plan vs. these
Safety margin at NOAEL
Monkey ePPND NOAEL exposure 27-fold clinical exposure (AUC); no NOAEL in 26-week study
“The safety margin to the anticipated clinical exposure was 27-fold (based on AUC).”
✓ VerifiedEMA assessment report, p. 29Source ↗
NOAEL / key findings
NOAEL was highest dose in 8-week studies (200 and 20 mg/kg/week); none in 26-week study (skin findings, GI infection deaths)
“The no-observed adverse effect level (NOAEL) was the highest dose tested in the 8-week studies (200mg/kg/week and 20mg/kg/week, respectively, for Study NCD2260 and Study NCD2384). Due to the severity of skin findings in some high-dose animals and mortalities in the low dose group consecutive to GI infection, no NOAEL could be determined in the 26-week study.”
