- Age at study initiation: approx. 8 weeks old
- Weight at study initiation: 143-189 grams
- Fasting period before study: Animals were deprived of food overnight prior to dosing and until 3-4 hours after administration of the test item. Water was available ad libitum.
- Housing: Group housing of 3 animals per cage in labeled Makrolon cages (MIV type; height 18 cm.) containing sterilized sawdust as bedding material (Lignocel S 8-15, JRS - J.Rettenmaier & Söhne GmbH + CO. KG, Rosenberg, Germany) and paper as cageenrichment (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd), Surrey, United Kingdom)

- Humidity (%): 40 to 70%
- Air changes (per hr): at least 10 air changes/hour
- Photoperiod (hrs dark / hrs light): 12-hour light/12- hour dark cycle
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- propylene glycol
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 2000 mg/kg (10 mL/kg) body weight
- Justification for choice of vehicle: The vehicle was selected based on trial preparations performed at Charles River Den Bosch and on test item data supplied by the Sponsor. The vehicle was chosen from (in order of preference): water (Elix) (test item did not dissolve), 1% aq. carboxymethyl cellulose (test item did not dissolve), propylene glycol (spec.gravity 1.036) (clear solution), polyethylene glycol 400 (spec. gravity 1.125) and corn oil (spec. gravity 0.92).
There was no information available regarding the solubility in vehicle.
MAXIMUM DOSE VOLUME APPLIED: 10 ml/kg
DOSAGE PREPARATION (if unusual): The preparations (w/w) were kept at room temperature and were dosed within 4 hours after adding the vehicle to the test item. Homogeneity was assessed by visual inspection of the solutions and the formulations were stirred during dosing, which ensures homogeneity sufficiently for these kinds of studies. Adjustment was made for specific gravity of the vehicle. No correction was made for purity of the test item as the correction factor is 1.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The toxicity of the test item was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 2000 mg/kg.
The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the
time interval between the dose groups. - Doses:
- 2000 mg/kg (10 mL/kg) body weight
- No. of animals per sex per dose:
- 3 females per dose
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 15 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily.
Body weights: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day
15. The signs were graded according to fixed scales and the time of onset, degree and duration were recorded:
Maximum grade 4: grading slight (1) to very severe (4)
Maximum grade 3: grading slight (1) to severe (3)
Maximum grade 1: presence is scored (1).
- Necropsy of survivors performed: yes; At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded. - Statistics:
- No statistical analysis was performed.
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.
- Clinical signs:
- other: Lethargy, uncoordinated movements, piloerection and/or hunched posture were noted for all animals on Day 1. Additionally, hunched posture was noted for two animals on Days 2 and 3.
- Body weight:
- other body weight observations
- Remarks:
- The mean body weight gain shown by the 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.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD50 value of T003422 in Wistar rats was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, T003422 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 (GHS) of the United Nations (2015) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).
