- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River Deutschland, Sulzfeld, Germany
- Females (if applicable) nulliparous and non-pregnant: Yes
- Age at study initiation: 11-12 weeks old.
- Weight at study initiation: 186-215 grams
- Fasting period before study: Yes, maximum 20 hours
- Housing: On arrival and following assignment to the study, animals were group housed (up to 5 animals of the same sex and same dosing group together) in polycarbonate cages (Makrolon MIV type; height 18 cm.) containing sterilized sawdust as bedding material (Lignocel S 8-15,
JRS - J.Rettenmaier & Söhne GmbH + CO. KG, Rosenberg, Germany) equipped with water bottles. These housing conditions were maintained unless deemed inappropriate by the Study Director and/or Clinical Veterinarian. The room(s) in which the animals were kept were documented in the study records. Animals were separated during designated procedures/activities. Each cage was clearly labeled.
- Diet (e.g. ad libitum): Pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany) was provided ad libitum throughout the study, except during designated procedures. The feed was analyzed by the supplier for nutritional components and environmentalcontaminants.
- Water (e.g. ad libitum): Municipal tap-water was freely available to each animal via water bottles. Periodic analysis of the water was performed, and results of these analyses are on file at the Test Facility.
- Acclimation period: At least 5 days.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 18-24 C
- Humidity (%): 40-70

MAXIMUM DOSE VOLUME APPLIED: No data
- Doses:
- 2,000 mg/kg
- No. of animals per sex per dose:
- 5 female
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Postdose observations were performed at periodic intervals on the day of dosing (at least three times) and once daily thereafter. The observation period was 14 days. All the animals were examined for reaction to dosing. The onset, intensity and duration of these signs was recorded (if appropriate). Signs were graded for severity and the maximum grade was predefined at 3 or 4. Grades were coded as slight (grade 1), moderate (grade 2), severe (grade 3) and very severe (grade 4). For certain signs, only its presence (grade 1) or absence (grade 0) was scored. Animals were weighed individually on Day 1 (predose), 8 and 15. A fasted weight was recorded on the day of dosing. Terminal body weights were collected from animals found dead or euthanized moribund after Day 1.
- Necropsy of survivors performed: Yes
- Other examinations performed: clinical signs, body weights, macroscopic examination upon necropsy
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- One animal was found dead on Day 2, no further mortality occurred.
- Clinical signs:
- other: Hunched posture, uncoordinated movements and/or piloerection were noted on Day 1 for the animals. In addition, lethargy was noted for the animal that was found dead.
- Gross pathology:
- No test item-related abnormalities were found at macroscopic post mortem examination of the animals. In the animal found dead, cannibalism of the abdominal region was noted at macroscopic post mortem examination. In one surviving animal ectopic splenic tissue was noted at macroscopic post mortem examination. This finding is occasionally seen in rats of this age and strain and was therefore considered not toxicologically significant.
Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- Based on the results of the study, the acute oral LD50 value of the test article is greater than 2,000 mg/kg.
- Executive summary:
The acute oral lethality potential of the test article was evaluated in female Wistar rats. The study was conducted according to OECD 425 (2008) and was performed in compliance with OECD GLP regulations. The test article was administered neat via oral gavage to a single rat at 2,000 mg/kg body weight for the pilot test. Subsequently, four additional female rats were dosed at 2,000 mg/kg body weight. Postdose observations were performed at periodic intervals on the day of dosing (at least three times) and once daily thereafter. The observation period was 14 days. All the animals were examined for reaction to dosing. The onset, intensity and duration of these signs was recorded (if appropriate). Signs were graded for severity and the maximum grade was predefined at 3 or 4. Grades were coded as slight (grade 1), moderate (grade 2), severe (grade 3) and very severe (grade 4). For certain signs, only its presence (grade 1) or absence (grade 0) was scored. Animals were weighed individually on Day 1 (predose), 8 and 15. A fasted weight was recorded on the day of dosing. Terminal body weights were collected from animals found dead or euthanized moribund after Day 1. One animal was found dead on Day 2, no further mortality occurred. Hunched posture, uncoordinated movements and/or piloerection were noted on Day 1 for the animals. In addition, lethargy was noted for the animal that was found dead. No test item-related macroscopic abnormalities were noted in the gross necropsy post mortem examination of the animals. Based on the results of the study, the acute oral LD50 value of the test article is greater than 2,000 mg/kg.
