- Age at study initiation: 10 weeks
- Weight at study initiation: 181.8 - 185.7 g
- Fasting period before study: 17 to 22 hours before treatment, with free access to water
- Housing: In groups of up to five in Makrolon type-4 cages during acclimatization. Individually in Makrolon type-3 cages during treatment and observation. Cages were equipped with wire mesh tops and standard softwood bedding including paper enrichment during treatment and observation.
- Diet (e.g. ad libitum): Pelleted rodent maintenance diet ad libitum, except for the overnight fasting period
- Water (e.g. ad libitum): Community tap water ad libitum

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22±3
- Humidity (%): 30-70
- Air changes (per hr): 10-15
- Photoperiod (hrs dark / hrs light): 12/12 - Route of administration:
- oral: gavage
- Vehicle:
- CMC (carboxymethyl cellulose)
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 55 and 200 mg/mL
- Amount of vehicle (if gavage):
94.5 mg/kg CMC (55 mg/mL preparation)
80 mg/kg CMC (200 mg/mL preparation)
Calculation: amount CMC in 10 mL preparation= 1% · (10000 mg preparation - x mg substance per 10000 mg preparation), where x is 550 and 2000 mg, respectively
- Justification for choice of vehicle: The vehicle was chosen after non-GLP solubility testing. Purified water and 0.5% CMC in purified water were found unsuitable vehicles for oral gavage application, as the test item could not be sufficiently dispersed in either vehicle. By grinding the test item in a mortar and pestle together with 1% CMC in purified water, a 20% (weight:weight) dispersion of the test item suitable for oral gavage application was obtained.
- Lot/batch no. (if required): 0001414646
- Purity: not reported
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg
DOSAGE PREPARATION (if unusual): Dose formulations were prepared shortly before each treatment using a magnetic stirrer and a spatula as homogenizers. The test item was weighed on a suitable precision balance and supplied to a mortar. By using a pestle, the test item and almost all of the vehicle was ground to a dispersion. This dispersion was transferred to a volumetric beaker and the vehicle was added up to the defined volume (weight:volume). Homogeneity of the test item in the vehicle was maintained during administration using a magnetic stirrer. - Doses:

- No. of animals per sex per dose:
- 1 female with 550 mg/kg bw
3 females with 2000 mg/kg bw - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The animals were examined daily during acclimatization and mortality and clinical signs were assessed. All animals were examined for clinical signs before treatment, once within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 to 15. Mortality was assessed before treatment, once within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 (with the clinical signs) and twice daily during test days 2 to 15. Body weights were recorded on the last day of acclimatization (prior to removal of food), on test day 1 (prior to treatment) and on test days 8 and 15.

- Executive summary:
An acute oral toxicity test with 4 animals (female RccHan:WIST(SPF) rat) was conducted under GLP according to OECD TG 425.
The animals were treated with the test item by gavage at doses of 550 and 2000 mg/kg body weight. Dosing started in one female animal at a dose level of 550 mg/kg. As no death occurred and no severe clinical signs were observed at this dose level, the next female was treated at a dose level of 2000 mg/kg. Two more females were treated at a dose level of 2000 mg/kg, as at this dose no deaths occurred and no severe clinical signs were observed.
All animals were examined for clinical signs before treatment, once within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 to 15. Mortality was assessed before treatment, once within the first
30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 (with the clinical signs) and twice daily during test days 2 to 15. Body weights were recorded on the last day of acclimatization (prior to removal of food), on test day 1 (prior to treatment) and
on test days 8 and 15. All animals were examined macroscopically after being sacrificed at the end of the observation period.
No deaths occurred during the course of the study. The animal treated with 550 mg/kg and two of the three animals treated with 2000 mg/kg showed ruffled fur after treatment on test day 1. In one animal treated with 2000 mg/kg, ruffled fur was still observed on test day 2. No clinical signs were observed in any animal during acclimatization and from test day 2 until the end of the observation period. The body weights were within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy.
The median lethal dose (LD50) of the test item after single oral administration to female rats, observed over a period of 14 days, is >2000 mg/kg body weight.

Additional information
Acute oral toxicity
An acute oral toxicity test with 4 animals (female RccHan:WIST(SPF) rat) was conducted under GLP according to OECD TG 425.
The animals were treated with the test item by gavage at doses of 550 and 2000 mg/kg body weight. Dosing started in one female animal at a dose level of 550 mg/kg. As no death occurred and no severe clinical signs were observed at this dose level, the next female was treated at a dose level of 2000 mg/kg. Two more females were treated at a dose level of 2000 mg/kg, as at this dose no deaths occurred and no severe clinical signs were observed.
All animals were examined for clinical signs before treatment, once within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 to 15. Mortality was assessed before treatment, once within the first
30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 (with the clinical signs) and twice daily during test days 2 to 15. Body weights were recorded on the last day of acclimatization (prior to removal of food), on test day 1 (prior to treatment) and on test days 8 and 15. All animals were examined macroscopically after being sacrificed at the end of the observation period.
Acute dermal toxicity
An acute dermal toxicity was assessed in a valid GLP study according to OECD TG 402.
5 male and 5 female RccHan:WIST (SPF) rats were treated with the test item at a dose level of 2000 mg/kg by dermal application. The test item was applied by weight as supplied by the Sponsor. For better dermal contact, the test item was moistened with purified water before application. All animals were examined for clinical signs before treatment, once within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 to 15. Local dermal signs were assessed once daily from test day 2 to 15. Mortality was assessed before treatment, once within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 (with the clinical signs) and twice daily during test days 2 to15. Body weights were recorded on test day 1 (prior to administration) and on test days 8 and 15. All animals were examined macroscopically after being sacrificed at the end of the study.
No deaths occurred during the course of the study and no clinical signs were observed. Four males and one female showed focal crusts after test item application lasting for a minimum of 2 and a maximum of 13 days. Brown discoloration of the skin was observed in all animals for a minimum of 7 days after test item application and lasted up to the end of the observation period in 3 males and 3 females. One female slightly lost body weight in the second week after treatment (2%). The body weights of the other animals were within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy.
The median lethal dose of the test item after single dermal administration to rats of both sexes, observed over a period of 14 days, is greater than 2000 mg/kg body weight.
