Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS

- Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: approximately 9-10 weeks
- Weight at study initiation: 156 - 185 grams

Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred
Number of dead animals in each test group with 3 animals each:
Females 2000 mg/kg: 0
Females 2000 mg/kg: 0 - Clinical signs:
- Hunched posture, flat posture, uncoordinated movements, shallow respiration, piloerection, ptosis, hypothermia and/or salivation were noted for all animals on Days 1 and/or 2.
- Body weight:
- The mean body weight gain shown by the surviving animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of all animals.
Any other information on results incl. tables
Final Report Amendment No. 1 was issued on 2018-09 -07. The amendment was issued at the request of the sponsor and the new Certificate of Analysis had no impact on the interpretation of the study results.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD50 value of T001596 in Wistar rats was established to exceed 2000 mg/kg body weight. According to OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, T001596 does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals of the United Nations (2015) and Regulation (EC) No 1272/2008 on classification, labelling and packing of substances and mixtures (including all amendments).
