Description of key information
A key study was completed for acute oral toxicity according to OECD Guideline 423 (Acute Oral toxicity - Acute Toxic Class Method) and EU Method b.1 tris (Acute Oral Toxicity - Acute Toxic Class Method). A key study was also completed for the acute dermal toxicity according to OECD Guideline 402 (Acute Dermal Toxicity), EU Method B.3 (Acute Dermal Toxicity), EPA OPPTS 870.1200 (Acute Dermal Toxicity), and Japanese Ministry of Agriculture, Forestry and Fisheries (JMAFF), 12 Nousan, Notification No 8147, November 2000; including the most recent partial revisions. Both of these studies were completed under GLP. An acute inhalation study was waived as exposure to humans via inhalation is not likely due to the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles, or droplets of inhalable size (exposure considerations).

The temperature and relative humidity were set to achieve limits of 19 to 25 C and 30 to 70% respectively. The rate of air exchange was at least 15 changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours of darkness.

- Vehicle:
- arachis oil
- Details on oral exposure:
- Using all available information on the toxicity of the test material, 2000 mg/kg was chosen as the starting dose.

- Control animals:

- Details on study design:
- All animals were dosed once only by gavage, using a metal cannula attached to a graduated syringe. The volume administered was calculated according to the fasted bodyweight at the time of dosing. Treatment of animals was sequential. Sufficient time was allowed between each group to confirm the survival of the previously dosed animals. The animals were observed for deaths or overt signs of toxicity 1/2, 1, 2 and 4 hours after the final dose and subsequently once daily for fourteen days. At the end of the observation period the animals were killed using ascending concentrations of carbon dioxide. All animals were subjected to gross pathological observations. This consisted of external examination and opening of the abdominal and thoracic cavities for examination of major organs. The appearances of any macroscopic abnormalities were recorded. No tissues were retained.

- TEST SITE
One day before exposure (Day -1) an area of approximately 5x7 cm on the back of the animal was clipped.
The preparation was applied on an area of approx. 10% of the total body surface, i.e. approx. 25 cm² for males and 18 cm² for females. The preparation was held in contact with the skin with a dressing, consisting of a surgical gauze patch, successively covered with aluminum foil and Coban elastic bandage. A piece of Micropore tape was additionally used for fixation of the bandages in females only.
Frequency: Single dosage, on Day 1.
REMOVAL OF TEST SUBSTANCE
Washing: 24 hours, after which dressings were removed and the skin cleaned of residual test item using tap water. - Duration of exposure:
- 24 hours.
- Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- VEHICLE
- Justification for choice of vehicle: The vehicle was selected based on trial preparation performed at WIL Research Europe and on test item data supplied by the Sponsor. There was no information available regarding the solubility or stability in vehicle.
Dose volume: 20 mL/kg body weight.
DOSAGE PREPARATION: The preparation (w/w) was kept at room temperature and 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 sufficient for these kinds of studies.
Duration of observation period following administration: 14 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.
- Necropsy of survivors performed: At the end of the observation period, all animals were euthanatised by oxygen/carbon dioxide procedure and subjected to necropsy. Death was confirmed by checking reflexes and heartbeat. Descriptions of all internal macroscopic abnormalities were recorded. - Statistics:
- None.
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Hunched posture (three males and three females) and/or chromodacryorrhoea (four males and one female) were noted between Days 1 and 3.
- Gross pathology:
- Pelvic dilation of the right kidney was found in one male animal, at macroscopic post mortem examination. Since this is occasionally seen among rats of this age and strain and it was found in one animal only, this was considered not toxicologically significant. Macroscopic examination of the other animals did not reveal any abnormalities.
- Other findings:
- Scales and/or white staining were seen on the skin of some animals during the observation period.
These local effects were considered not to have affected the conclusion of the study. - Interpretation of results:
- not classified
- Conclusions:
- In an acute dermal toxicity study with rats, performed according to OECD 402 test guideline and GLP principles, an LD50 >2000 mg/kg bw was determined.
- Executive summary:
BMS-587172 -01 was tested in an acute dermal toxicity study with rats, performed according to OECD 402 test guideline and GLP principles. No mortality occurred. Hunched posture (three males and three females) and/or chromodacryorrhoea (four males and one female) were noted between Days 1 and 3. Pelvic dilation of the right kidney was found in one male animal, at macroscopic post mortem examination. Since this is occasionally seen among rats of this age and strain and it was found in one animal only, this was considered not toxicologically significant. Macroscopic examination of the other animals did not reveal any abnormalities.
Based on the rsults of this study, the dermal LD50 value of BMS-587172-01 in Wistar rats was established to exceed 2000 mg/kg body weight.

Additional information
Justification for classification or non-classification
The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley CD strain rat was estimated as being greater than 2000 mg/kg bodyweight. The dermal LD50 value in Wistar rats was established to exceed 2000 mg/kg body weight. Therefore, the substance is not classified according to the EU CLP regulation.
