Description of key information
Acute oral toxicity:
In an acute oral toxicity study in HanRcc: Wist(SPF) rats, following the acute toxic class method in accordance with the OECD guideline n° 423 and EU Method B.1 tris, the LD50 was determined to be 1000 mg/kg bw for female animals. The study has been performed in compliance with GLP (Van Sas P, 2017).
Acute inhalation toxicity:
No study is available. This endpoint is waived based on the following justification. A key study is available for the oral and dermal route of exposure. According to the REACH regulation, for substances other than gasses, only one additional route of exposure should be tested other than the oral route of exposure for acute toxicity (column 2, Annex VIII, section 8.5). Therefore, it is not necessary to perform an acute toxicity test via inhalation.
Acute dermal toxicity
In an acute dermal toxicity study in female wistar rats performed acording to the OECD guideline 402, the LD50 was established to exceed 2000 mg/kg bw (Van Sas P, 2019)

Additional information
Acute oral Toxcity
An acute oral toxicity test was performed with T002632 according to the OECD guideline 423.
T002632 was administered by oral gavage to three female Wistar rats at 2000 mg/kg body weight. In a stepwise procedure two
additional groups of three females were dosed at 300 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed on the day of death or after terminal sacrifice (Day 15).
At 2000 mg/kg, two animals were found dead on Day 1 or 2. At 300 mg/kg, no mortality occurred.
At 2000 mg/kg, uncoordinated movements, ptosis, piloerection and/or hunched posture were noted for the two animals found dead. The surviving animal showed lethargy, hunched posture, uncoordinated movements, piloerection, lean appearance
and ptosis between Days 1 and 13. At 300 mg/kg, piloerection and uncoordinated movements were noted for all animals on Day 1. Hunched posture was noted for three of the animals on Day 1.
The surviving animal at 2000 mg/kg showed reduced body weight gain during the first week and regained weight during the second week. At 300 mg/kg, the 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.
For one animal found dead, macroscopic post mortem examination revealed abnormalities of the stomach (greenish discoloration of the glandular mucosa),duodenum (gelatinous content), jejunum (gelatinous content) and ileum (gelatinous content). For the other animal found dead, macroscopic post mortem examination revealed abnormalities of the gastrointestinal tract (gelatinous content), trachea (gray white foamy content) and lungs (gray-white foamy content). Macroscopic post mortem examination of the surviving animals did not reveal any abnormalities.
The oral LD50 value of JNJ-26144612-AAA (T002632) 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 1000 mg/kg body weight.
Acute inhalation toxicity
A key study is available for the oral and dermal route of exposure. According to the REACH regulation, for substances other than gases, only one additional route of exposure should be tested other than the oral route of exposure for acute toxicity (column 2, Annex VIII, section 8.5). Therefore, it is not necessary to perform an acute toxicity study via the inhalation route of exposure.
Acute dermal Toxicity
An acute dermal toxicity test was performed with T002632 according to the OECD guideline 402 (van Sas P, 2019). Initially, the test item was administered to a single female Wistar Han rat by a single dermal application at 2000 mg/kg body weight for24 hours in range finder study. Based on the results in the single female, the amin study was performed by dosing two females at 2000 mg/kg. All animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed on the day of death or after terminal sacrifice (Day 15).
No mortality occurred. Chromodacryorrhoea of the snout was noted for two animals on Day 1 and hunched posture was noted for the other animal on Day 2. No further clinical signs were noted. No test item related erythema and edema was noted for the treated skin between Days 2 and 4. The changes noted in body weight gain 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 JNJ-26144612-AAA (T002632) in Wistar Han rats was established to exceed 2000 mg/kg body weight.
Justification for classification or non-classification
Based on the results on oral LD50 ranging between 300 - 2000 mg/kg/bw and according to the criteria laid down in the EC regulation No 1272/2008 on classification, labelling and packaging of substances and mixtures, T002632 should be classified as 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, T002632 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.
