Applicant's summary and conclusion

Conclusions:
The NOEL in one-generation reproduction toxicity study in female rats by oral route was 50 mg/kg/day both for mother and offspring (F0 and F1).
The NOAEL in one-generation reproduction toxicity study in female rats by oral route was 100 mg/kg/day both for mother and offspring (F0 and F1).
