Hibsago: what safety margin did regulators accept?
bepirovirsen · HBV RNA (ASO)
Safety margin at NOAEL
Mouse embryo-fetal/pre- and postnatal study: no adverse effects at 0.7x MRHD (BSA); no repeat-dose margin stated
“No adverse effects on embryofetal development, parturition, or on the postnatal development of the offspring were observed following subcutaneous administration of bepirovirsen to pregnant mice during organogenesis and throughout pregnancy and lactation [Gestation day (GD) 0 to 15 and from GD 6 to lactation day (LD) 21], at 0.7 times the MRHD based on BSA comparison.”
NOAEL / key findings
NOAEL not stated; 2-year mouse: hepatocellular carcinomas at ≥10 mg/kg; liver adenomas and hemangiosarcomas at 30 mg/kg (males)
“In male mice, statistically significant increases in tumor incidences were observed compared to controls in liver (hepatocellular carcinomas at ≥10 mg/kg; hepatocellular adenomas, combined hepatocellular adenomas/carcinomas, hemangiosarcomas, and combined hemangiosarcomas/hemangiomas at 30 mg/kg)”
