TREATMENT OF TEST MATERIAL PRIOR TO TESTING : Test article dosed neat
Test animals
- Species:

- Strain:
- Wistar
- Sex:
- female
- 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: Approximately 12 weeks old.
- Weight at study initiation: 163-209 grams
- Fasting period before study: 20 hours.
- Housing: On arrival and following assignment to the study, animals were group housed (up to 3 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. The room in which the animals were kept was 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.
- Water (e.g. ad libitum): Municipal tap-water was freely available to each animal via water bottles
- Acclimation period: At least 5 days
- Microbiological status when known : No data
- Method of randomisation in assigning animals to test and control groups : Animals were assigned to the study at the discretion of the coordinating bio technician according to body weights, with all animals within ± 20% of the sex mean. Animals in poor health or at extremes of body weight range were not assigned to the study.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 20-21
- Humidity (%): 38-51
- Air changes (per hr): At least 10
- Photoperiod (hrs dark / hrs light): 12/12
IN-LIFE DATES: From: 28 March, 2019 To: 16 April, 2019
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- VEHICLE: None, dosed neat.
MAXIMUM DOSE VOLUME APPLIED: No data
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The test article is not expected to be acutely lethal via ingestion so the test article was administered at 2000 mg/kg to 3 female rats. As there were not adverse clinical signs or mortality, a group of 3 additional female rats were dosed at 2000 mg/kg. - Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Throughout the study, animals were observed for general health/mortality and moribundity twice daily, in the morning and at the end of the working day. Animals were not removed from cage during observation, unless necessary for identification or confirmation of possible findings. 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.
- Necropsy of survivors performed: Yes, all animals were sacrificed by oxygen/carbon dioxide procedure at the end of the observation period. All animals assigned to the study were subjected to necropsy and descriptions of all internal macroscopic abnormalities were recorded.
- Clinical signs including body weight
- Other examinations performed: clinical signs, body weight, gross pathology - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).

Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The oral LD50 value of MTDID 18990 in Wistar Han rats was established to exceed 2000 mg/kg body weight.
- Executive summary:
The acute oral lethality potential of MTDID 18990 was evaluated in Wistar rats. The study was conducted according to OECD 423 in compliance with OECD GLP. Rats (6 females) received 2000 mg/kg MTDID 18990 “neat” as a liquid via oral gavage. No mortality occurred. Clinical observations of toxicity included hunched posture (6/6 rats on Days 1 and 2 and one animal on Day 3), uncoordinatedmovements (3/6 females at 2 and 4 hours post-dose; only the second set of dosed animals), and piloerection (6/6 rats through 4-hours post-dose). The mean body weight gain shown by the animals over the study in-life period was considered to be similar to that expected for normal untreated animals of the same ageand strain. No abnormalities were found at macroscopic post mortem examination of the animals. The rat oral LD50 is >2000 mg/kg with significant signs of clinical toxicity (i.e., hunched posture and uncoordinated movements). Based on the results of the study, the acute oral LD50 of MTDID 18990 is greater than 2,000.
