Administration / exposure
- Route of administration:

- Details on oral exposure:
- The animals were marked for individual identification by tail painting.
Prior to the administration a detailed clinical observation was made of all animals.
Prior to the administration food was withheld from the test animals for 16 to 19 hours (access to water was permitted). Following the period of fasting the animals were weighed and the test item was administered. Food was provided again approximately 4 hours post dosing.
The test item was administered at a single dose by gavage using a feeding tube.
The test item was administered at a dose volume of 10 mL/kg body weight. - Doses:
- Dose Level
The starting dose was selected to be 2000 mg/kg body weight. Compound-related mortality was recorded for 2 animals of step 1. Based on these results and according to the acute toxic class method regime, a second step was performed at a dose of 300 mg/kg body weight. No compound-related mortality was
recorded for any animal of step 2. Based on these results and according to the acute toxic class method regime, a third step was performed at a dose of
300 mg/kg body weight. No compound-related mortality was recorded for any animal of step 2. Based on these results and according to the acute toxic
class method regime no further testing was required. - No. of animals per sex per dose:
- 2000: 3
300: 6 - Control animals:
- no
- Details on study design:
- Observation Period
The surviving animals were observed for 14 days after dosing for general clinical signs, morbidity and mortality.
Weight Assessment
The animals were weighed on day 1 (prior to the administration) and on days 8 and 15.
Clinical Examination
A careful clinical examination was made several times on the day of dosing (at least once during the first 30 minutes and with special attention given during the first 4 hours post-dose). As soon as symptoms were noticed they were recorded. Thereafter, the animals were observed for clinical signs once daily until the end of the observation period. All abnormalities were recorded.
Cageside observations included changes in the skin and fur, eyes and mucous membranes. Also respiratory, circulatory, autonomic and central
nervous systems and somatomotor activity and behavior pattern were examined. Particular attention was directed to observations of tremor,
convulsions, salivation, diarrhoea, lethargy, sleep and coma.
Pathology
At the end of the observation period the surviving animals were sacrificed with an overdosage of pentobarbital injected intraperitoneally (Narcoren®, Merial; lot no.:231073 31 July 2017) at a dosage of approximately 8 mL/kg bw.
All animals were subjected to gross necropsy. All gross pathological changes were recorded and in case of findings the tissues were preserved for a possible histopathological evaluation. The preserved tissues of which no histopathological evaluation was made will be discarded 3 months after the release of the final report unless otherwise agreed upon with the sponsor. - Statistics:
- According to OECD guidelines, the biological relevance of the results is the criterion for the interpretation of results, a statistical evaluation of
the results is not regarded as necessary.

Summary Results
One group of three female WISTAR Crl: WI(Han) rats, were treated with the test item by oral gavage administration at a dosage of 2000 mg/kg body weight. The test item was suspended in the vehicle DMSO and PEG400 (ratio 1:5)at a concentration of 0.2 g/mL and administered at a dose volume of 10 mL/kg.
Two groups, each of three female WISTAR Crl: WI(Han) rats, were treated with the test item by oral gavage administration at a dosage of 300 mg/kg body weight. The test item was suspended in the vehicle DMSO and PEG400 (ratio 1:5) at a concentration of 0.03 g/mL and administered at a dose volume of 10 mL/kg.
All animals used in the study after their entrance at BSL were allowed to acclimatise to the laboratory conditions for at least 5 days. The animals were observed on delivery, on inclusion in the study and before administration for mortality/morbidity and other clinical signs. All animals were examined for clinical signs several times on the day of dosing and once daily until the end of the observation period. Their body weights were recorded on day 1 (prior to the administration) and on days 8 and 15.All animals were necropsied and examined macroscopically. Two animals treated with the test item at a dose of 2000 mg/kg bw were found dead on the second day of observation. The remaining animal survived until the end of the study.
The most relevant clinical findings in the animals treated with the test item at a dose of 2000 mg/kg bw were reduced spontaneous activity, piloerection, eyes half closed, catalepsies, kyphosis, bradykinesia and wasp waist. The most relevant clinical signs persisted on the day of treatment in all animals. The surviving animal recovered from all clinical signs on the fifth day of the observation period.
The most relevant clinical findings in the animals treated with the test item at a dose of 300 mg/kg bw were reduced spontaneous activity, piloerection, eyes half closed, catalepsies, kyphosis, bradykinesia and wasp waist. The most relevant clinical signs persisted on the day of treatment in all animals. All animals recovered from all clinical signs on the third day of the observation period.
Throughout the 14-day observation period, the weight gain of the surviving animals was within the normal range of variation for this strain.
