Endpoint summary
Administrative data
Description of key information
- Acute toxicity: Oral
- Acute toxicity: Inhalation
- Acute toxicity: Dermal
In an acute oral toxicity study in female Crl:WI (Han) (SPF) rats, following the acute toxic class method in accordance with the OECD Guideline 423 and EU Method B.1 tris, the LD50 was established to be in the range of 300 - 2000 mg/kg. According to the OECD 423 guideline, the LD50 cut-off value was considered to be 2000 mg/kg body weight (WIL, 2016).
No reliable acute toxicity study via the inhalation route was available. However, this endpoint is waived as specific data are available for the oral and dermal exposure routes.
In an acute dermal toxicity study in male and female Crl:WI (Han) (SPF)
rats, following the standard acute method according to OECD Guideline
402 and EC method B.3, the LD50 was established to exceed 2000 mg/kg
body weight. (WIL, 2016).

- Mortality:
- At 2000 mg/kg, four out of eight animals were found dead on Day 2. (The test was performed three times: 1st test: 2 of 3 animals died (1 animal excluded from interpretation), 2nd test: 0 animals died, 3th test: 3 of 3 animals died
At 300 mg/kg, no mortality occurred. - Clinical signs:
- other: At 2000 mg/kg, lethargy, hunched posture, quick breathing, shallow respiration, piloerection and/or ptosis were noted for all animals on Days 1 and/or 2. At 300 mg/kg, hunched posture, piloerection and/or ptosis were noted for all animals on Day 1.
- Gross pathology:
- At 2000 mg/kg, abnormalities of the body cavities (Thoracic cavity: contains watery-clear fluid) were noted for all animals found dead.
At 300 mg/kg, macroscopic post mortem examination did not reveal any abnormalities.
Autolysis was noted for all animals found dead at 2000 mg/kg. This was considered not toxicologically relevant. - Other findings:
- One of the animals (no. 3) that was dosed at 2000 mg/kg and was found dead on Day 2, showed a perforated esophagus at macroscopic post mortem examination. During observations for clinical signs hunched posture, piloerection and ptosis were noted for this animal on Day 1. Further, watery clear fluid in the thoracic cavity and autolysis were noted at macroscopic examination.
Since it could not be excluded that this mortality occurred due to a gavage error the data obtained from this animal were excluded from the study results. However, it was considered that sufficient data were available from the remaining animals for proper evaluation of the study. - Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- Based on these results:
- according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments), T001141 should be classified as: harmful if swallowed (Category 4) for acute toxicity by the oral route;
- according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments), T001141 should be classified as Category 4 and should be labeled as H302: Harmful if swallowed.

Additional information

- Acute dermal Toxicity:
An acute oral toxicity study with T001141 according to the acute toxic class method in female Crl:WI (Han) (SPF) rats (OECD guideline 423 and EU Method B.1 tris) was performed (WIL 2016). Single dosages of 2000 mg/kg bw (3 groups each of 3 animals) and 300 mg/kg bw (2 groups each of 3 animals) were applied. The substance was formulated in 1% aqueous CMC (carboxymethyl cellulose) at concentrations of 200 mg/ml and 30 mg/ml respectively. The rats received a single oral dose of test item, and were observed during 14 days following administration. Lethality and viability were observed twice daily, and bodyweight was monitored at day 1 (prior to administration), 8 and 15. Clinical signs were observed at periodic intervals on the day of dosing (day 1) and once daily thereafter. Necropsy of survivors and macroscopic examination were also performed. Internal macroscopic abnormalities were recorded.
At 2000 mg/kg, four out of eight animals were found dead on Day 2. (The test was performed three times: 1st test: 2 of 3 animals died [1 animal excluded from interpretation], 2nd test: 0 animals died, 3rd test: 3 of 3 animals died). At 300 mg/kg, no mortality occurred. Clinical signs oberved: At 2000 mg/kg, lethargy, hunched posture, quick breathing, shallow respiration, piloerection and/or ptosis were noted for all animals on Days 1 and/or 2. At 300 mg/kg, hunched posture, piloerection and/or ptosis were noted for all animals on Day 1.
The body weight gain shown by the surviving animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. At 2000 mg/kg, abnormalities of the body cavities (Thoracic cavity: contains watery-clear fluid) were noted for all animals found dead. At 300 mg/kg, macroscopic post mortem examination did not reveal any abnormalities. Autolysis was noted for all animals found dead at 2000 mg/kg. This was considered not toxicologically relevant.
With these results, the oral LD50 value of T001141 in Wistar rats was established to be within the range of 300-2000 mg/kg body weight. According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 2000 mg/kg body weight. The study is rated K1 and is selected as key study.
An additional supporting study on acute oral toxicity in rats was performed, and the oral LD50-value of substance T001141 was determined to be > 640 mg/kg bw (J&J PRD).
In addition to the oral route of exposure, for substances other than gases, the information mentioned under REACH section 8.5.2 to 8.5.3 shall be provided for at least one other exposure route (REACH Regulation, column 2 adaptation of Annex VIII). For this substance a key study is available for the dermal route of exposure. Therefore, an acute inhalation toxicity study should not be performed.
An acute dermal toxicity study with T001141 according to the standard acute method in male and female Crl:WI (Han) (SPF) rats (OECD guideline 402 and EU Method B.3 was performed (WIL, 2016). The substance was dissolved in 1% aqueous CMC (carboxymethyl cellulose) and applied on a clipped area on the back at 2000 mg/kg bw. The test item was then wrapped with a surgical gauze patch (Surgy 1D), successively covered with aluminum foil and Coban elastic bandage. After 24 h hours of exposure remainings of the test item were washed-off. The animals were observed during 14 days. Lethality and viability were observed twice daily, and bodyweight was monitored at day 1 (prior to administration), 8 and 15. Clinical signs were observed at periodic intervals on the day of dosing (day 1) and once daily thereafter, until day 15. Necropsy of survivors and macroscopic examination were also performed. Internal macroscopic abnormalities were recorded.
No mortality occurred. No clinical signs of systemic toxicity were noted. The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity. No abnormalities were found at macroscopic post mortem examination of the animals.
The dermal LD50 value of T001141 in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for classification or non-classification
Based on the results showing an LD50 between 300 - 2000 mg/kg bw and according to the criteria laid down in Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures, T001141 should be classified as acute oral toxic category 4 and should be labeled as H302: Harmful if swallowed.
No data were available to decide on the classification for the inhalation route.
Based on the dermal LD50 exceeding 2000 mg/kg bw, T001141 does not have to be classified and has no obligatory labelling requirement for acute dermal toxicity according to the criteria laid down in Regulation (EC) No 1272/2008.
