Applicant's summary and conclusion
- Interpretation of results:

- Executive summary:
In an acute dermal toxicity GLP study according to OECD 402, groups of five male and five female Hanlbm: WIST (SPF) rats were treated with Y-15099 at 2000 mg/kg bw by dermal application under semi-occlusive conditions (Damme, 2001). The test item was applied undiluted as delivered from the sponsor at a volume of 2 mL/kg bw. The animals were examined for clinical signs four times during the test day 1 and once daily during test days 2 – 15. Mortality/viability was recorded together with clinical signs at the same time intervals on test day 1. During test days 2 – 15 it was recorded two times a day. Body weights were recorded on day 1 prior to administration and on days 8 and 15. On day 15 all animals were euthanized and examined macroscopically. No deaths occurred during the study. No clinical signs of toxicity were observed during the observation period. 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 dermal administration to rats of both sexes, observed over a period of 14 days is greater than 2000 mg/kg body weight.
