- Details on results:
- Desquamation noted in males given 500 and 1000 mg/kg/day was no longer observed after 10 days of dosing and was not observed in females. This finding was explained by the fact that residues of the test item on the application site sometimes resembled desquamation. Scabs were most frequently noted in treated males. Although, this finding did not appear in controls, no dose-relationship could be observed. For half of the concerned animals, the presence of this lesion did not exceed one week and was observed during 2 to 10 weeks for the other half. This finding was considered not related to the test item because the scabs were limited in frequency, did not occur in both high-dose groups, and readily resolved during the dosing period for most of the animals. Very slight erythema was noted in treated animals with a very low incidence and during a very short period. Thus, this finding was not considered to be related to treatment with test item. Areas of hair loss were observed in males and females of all groups with a low incidence. Since this hair loss was located outside the treated area (left and right forelimbs, abdomen, thorax or neck), it was not considered to be due to the treatment with the test item but considered to be of spontaneous occurrence. No signs of systemic toxicity were noted.
A slightly lower mean body weight gain was noted in males given 1000 mg/kg/day with a protective collar. Since, this was not observed in males given 1000 mg/kg/day without protective collar and not observed in females, a relationship to treatment with the test item is not indicated.
The estrous cycle stage was not affected at any dose-level since normal cyclicity was observed in all females.
Compared to vehicle control group, a slightly higher mean cell volume was noted in males with collar given 1000 mg/kg/day (52.4 fL vs. 49.9 fL) and in females of both groups given 1000 mg/kg/day (55.3 and 54.8 fL vs. 53.5 fL, respectively). A slightly lower mean cell hemoglobin concentration was observed in males given 250 mg/kg/day (35.6 g/dL vs. 36.4 g/dL) and in animals given 500 and 1000 mg/kg/day (both groups) (males: 35.4; 35.4 and 35.4 g/dL vs. 36.4 g/dL; females: 35.9, 35.8 and 35.9 g/dL vs. 36.5 g/dL). Since these differences were slight, with individual values in the physiological range and no histopathological findings were noted, they were considered to be of no toxicological significance.
The plasma levels of the test item measured in animals given 1000 mg/kg/day with or without collar were very low and indicated that the test item was not bioavailable by cutaneaous route. Because of the very low levels in the high-dose groups, the samples for lower dose groups were not analyzed. On the untreated and treated areas of skin, the main microscopic changes were minimal to slight hyperkeratosis sometimes with parakeratosis, acanthosis, spongiosis and empty hair follicles. As the incidence and severity of these findings were not dose-related, often lower in the animals of the high-dose group wearing a protective plastic collar than in the animals of the high dose group without protective collar, and without prominent differences between the untreated and treated areas, these skin microscopic changes were considered to be unrelated to any irritant potency of the test item and most likely due to mechanical injuries incurred during dose-site preparation (clipping, cleaning etc...).

Applicant's summary and conclusion
- Conclusions:
- The test item, FAT 70’884/C (batch No. 02464CL3), was administered dermally to Wistar Han rats at the dose-levels of 250, 500 and 1000 mg/kg/day for 13 weeks. No clinical signs, hematological, blood biochemical, urinary or histopathological findings were observed at any dose-level. Plasma levels indicated that the test item was not bioavailable. Consequently, under the experimental conditions of the study, the No Observed Adverse Effect Level (NOAEL) of the test item is >= 1000 mg/kg/day.
- Executive summary:
Four treated groups of 13 male and 13 female Wistar Han rats (including three satellite males and three satellite females) received the test item, FAT 70’884/C (batch No. 02464CL3), daily by cutaneous application at the dose-levels of 250, 500, 1000 (without protective collar) or 1000 mg/kg/day (with protective collar) for 13 weeks. An additional group of 10 males and 10 females received the vehicle alone (polyethylene glycol 400) under the same experimental conditions and acted as a control group. Animals of the second high-dose group (given 1000 mg/kg/day) wore a protective plastic collar over at least a 6-hour period after each application. After the exposure period, the application site of these animals was cleaned with tap water and dried with absorbent paper.
The animals were checked daily for mortality and clinical signs. Detailed clinical examinations were performed before the beginning of the treatment period and then once a week. Body weight and food consumption were recorded once a week during the study. Neurotoxic evaluation using functional observation battery (FOB) was carried out at the end of the treatment period on animals of the vehicle control and high-dose groups (without collar). Ophthalmological examinations were performed on animals of the vehicle control and high-dose groups (without collar). The estrous cycle stage was determined for 14 consecutive days during weeks 11 and 12 for each female. Hematology, blood biochemical investigations and urinalysis were performed at the end of the treatment period. Satellite animals were allocated for the determination of the test item plasma levels and were sampled prior to dosing, on day 8 and weeks 6 and 13. On completion of the treatment period, the animals were killed and submitted to a full macroscopic post-mortem examination. Designated organs were weighed and selected tissue specimens were preserved. A microscopic examination was performed on selected tissues from animals of the vehicle control and the two high-dose groups and on all macroscopic lesions in the low- and mid-dose groups.
No clinical signs, hematological, blood biochemical, urinary or histopathological findings were observed at any dose-level. Plasma levels indicated that the test item was not bioavailable. Consequently, under the experimental conditions of the study, the No Observed Effect Level (NOEL) of the test item is 1000 mg/kg/day or above.
