Applicant's summary and conclusion
- Conclusions:
- The NOEL/NOAEL for reproductive and developmental toxicity in rats were determined to be 1000 mg/kg bw/day since no effects were observed in the highest dose tested.
- Executive summary:
A combined repeated dose toxicity study with the reproduction/developmental screening test was performed with the test item according to OECD Guideline 422 (GLP study). Based on a preliminary 14 -days range-finding study, test item was administered orally to 12 male and female rats at 0 (control), 40, 200 and 1000 mg/kg bw/day for 42 days (from 14 days before mating, and through the mating period until a day before necropsy) and for 41-48 days (from 14 days before mating, and through the mating period until day 4 of lactation) respectively, to evaluate reproductive ability and viability and development of pups. Parental animals were subjected to necropsy at the end of the dosing. Pups were necropsied at Day 5 of lactation. No animals died in any test article group, and no test article related changes were observed in clinical signs, detailed observations, grip strength, locomotor activity, body weight, food consumption, hematology, blood chemistry, urinalysis (only performed in males), organ weight, necropsy, or histopathology. Related to the reproductive and developmental toxicity parameters, no test article-related changes were observed in any group in estrous cycle examination, copulation rate, fertility rate, gestation period, number of corporea lutea, number of implantations, implantation index, gestation index, delivery index, or nursing behaviour in dams. With respect to examination of pups, no test article related changes were observed in the number of pups delivered, number of live pups, live birth index, viability index or sex ration on Day 0 after birth, number of live pups, viability index or sex ration on Day 4 after birth, clinical signs, external examinations, body weight or necropsy. Accordingly, it was considered that the test article did not affect the developmental or growth of next generation. Based on these results, the NOEL/NOAEL for reproductive and developmental toxicity in rats was determined to be 1000 mg/kg bw/day since no effects were observed at the highest dose tested.
