Applicant's summary and conclusion

Conclusions:
Based on the experimental conditions of this study :
- the No Observed Adverse Effect Level (NOAEL) for parental toxicity was considered to be 1000 mg/kg/day
- the No Observed Effect Level (NOEL) for toxic effects on progeny was considered to be 1000 mg/kg/day in the absence of any treatment-related effect on pups at this dose-level
