Applicant's summary and conclusion

- Executive summary:
In an acute oral toxicity GLP study according to OECD 423, one group of three male and three female HanBrl: WIST (SPF) rats was treated by oral gavage with Y-15099 at 2000 mg/kg body weight. The test item was applied undiluted in volume of 2 mL/kg bw. The animals were examined for clinical signs daily during the acclimatization period, four times during test day 1 and once daily during test days 2 – 15. Mortality and viability were recorded daily during the acclimatization period and together with clinical signs at the same time intervals on test day 1 and at least once daily on test days 2 – 15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. On day 15 all animals were necropsied and examined macroscopically. All animals survived until the end of the study period. No clinical signs were evident during the course of the study. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were observed at necropsy.
The median lethal dose of Y-15099 after single oral administration to rats of both sexes, observed over a period of 14 days is greater than 2000 mg/kg body weight.
