Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 200 mg/mL
- Justification for choice of vehicle:
The vehicle used in the study was selected from the results of solubility assays performed by CIToxLAB France prior to the preliminary assay.
The solubility assay first started with drinking water treated by reverse osmosis and 0.5% methylcellulose aqueous solution and was not satisfactory. However, a yellow suspension was obtained at 200 mg/mL with corn oil.
- Maximum dose-volume applied: 20 mL/kg.
DOSAGE PREPARATION (if unusual):
The test item was administered as a homogeneous suspension in the vehicle. The test item was mixed under magnetic agitation with the required quantity of vehicle.
Dose formulations preparations were prepared by the CiToxLAB France Pharmacy extemporaneously on the day of each administration.
The dose formulations were stored at room temperature and delivered to the study room in brown flasks.
CLASS METHOD (if applicable):
Rationale for dose-level selection
The starting dose-level was selected in agreement with the Sponsor, based on the following rationale:
- based on available test item toxicity data, no morbidity or mortality was expected to occur at the dose level of 2000 mg/kg. This was therefore chosen as the starting dose-level. - Doses:
- 2000 mg/kg.
- No. of animals per sex per dose:
- 3 females per treatment step
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Clinical observations: frequently during the hours following treatment; then, at least once a day.
- Body weight: just before treatment on day 1; then on days 8 and 15.
- Necropsy of survivors performed: yes (macroscopic). - Statistics:
- no
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD0
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- No unscheduled deaths occurred during the study.
- Clinical signs:
- other: Piloerection was observed in 4/6 females within 4 hours after treatment. No clinical signs persisted from day 2.
- Gross pathology:
- The only macroscopic finding noted (red discoloration in the thymus in a single female) at the end of the observation period is commonly recorded in the Sprague-Dawley rat and was considered to be incidental and not to be related to the test item administration.
- Other findings:
- no
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD0 of the test item was higher than 2000 mg/kg in rats.
- Executive summary:
The objective of this study was to evaluate the potential acute toxicity of the test item following a single oral administration (gavage) to rats,according to OECD No. 423 (2001) and EU Method B.1tris (2008) guidelines.
This study was conducted in compliance with the principles of Good Laboratory Practice.
Methods
The test item was administered once by oral route (gavage) to two groups of three fasted female Sprague-Dawley rats under a dosage-volume of 10 mL/kg. The test item was prepared in corn oil.
Based on available test item toxicity data, the starting dose-level of 2000 mg/kg was chosen. After the first assay, as no toxicity was observed, the results were confirmed in three other females.
Each animal was observed at least once a day for mortality and clinical signs for 15 days. Body weight was recorded on day 1 and then on days 8 and 15.
On completion of the observation period, the animals were sacrificed and then submitted for a macroscopic post-mortem examination. Macroscopic lesions were preserved in buffered formalin then destroyed at the finalization of the study reportas no microscopic examination was performed.
Results
No unscheduled deaths occurred during the study.
Piloerection was observed in 4/6 females within 4 hours after treatment. No clinical signs persisted from day 2.
When compared to CiToxLAB France historical control data, a lower body weight gain was noted in 3/6 females between day 8 and day 15.
The test item administration did not induce any macroscopic changes.
Conclusion
The oral LD50of the test item was higher than 2000 mg/kg in rats.
Therefore, the test item is not classified as toxic or harmful by oral route according to the criteria of CLP Regulation.
