Annex 3
Dose descriptor:
NOAEL
Effect level:
<= 300 mg/kg bw/day
Based on:
test mat.
Sex:
male/female
Basis for effect level:
other: for offspring growth, based on the low birthweight and low bodyweight gain seen in litters where the females were dosed at 1000 mg/kg/day
Remarks on result:
other: Generation: F0 (migrated information)
The mean number of implantations, the live litter size on Day 1, the offspring survival up to
Day 7 of age and sex ratio showed no adverse effect of parental treatment. Offspring
bodyweight on Day 1 of age and subsequent bodyweight gain up to Day 7 of age were similar
to control values for the litters of females receiving CI-166 at 100 and 300 mg/kg/day but
were significantly lower at 1000 mg/kg/day. Macroscopic examination of offspring killed at
scheduled termination on Day 7 of age revealed no abnormality.
