Furthermore, an additional blood sample (0.5 mL) was be collected into serum tubes for possible future measurement of thyroid releasing hormone (TSH), and the thyroid hormones triiodothyronine (T3) and thyroxine (T4) (added by amendment if applicable). Serum samples are stored at -80 ± 10°C. Any samples remaining at finalization of the study report, were discarded. - Statistics:
- Blood parameters:
For parameters with bidirectional changes:
Non-parametric one-way analysis using KRUSKAL-WALLIS test. If the resulting p-value was equal or less than 0.05, a pairwise comparison of each dose group with the control group was performed using WILCOXON-test (two-sided) for the hypothesis of equal medians

Pairwise comparison of each dose group with the control group using the WILCOXON-test (one-sided) for the hypothesis of equal medians

Results and discussion
Results of examinations
- Clinical signs:
- effects observed, treatment-related
- Description (incidence and severity):
- 300 mg/kg bw/d:
- several clinical signs were noted over the whole treatment with earliest onset on the fourth day of treatment: bedding in mouth, breathing noises and labored breathing, ruffled fur, visible weight loss and generally weakened condition
100 mg/kg bw/d:
- isolated breathing noises recorded in two males and one female. Based on the low incidence and transient occurrence, these findings were not considered to be toxicologically relevant.
30 mg/kg bw/d:
- ruffled fur was intermittently noted in one male and in one female. Based on the low incidence and transient occurrence, these findings were not considered to be toxicologically relevant. - Mortality:
- mortality observed, treatment-related
- Description (incidence):
- Three males and one female treated at 300 mg/kg bw/day did not survive until the scheduled necropsy.
- One male and one female were killed for humane reasons after 28 days of treatment. Marked body weight loss, ruffled fur, labored breathing and breathing noises along with a generally weakened condition were observed.
- Two males died spontaneously on day 25 of the pairing period and day 1 of the after pairing period, respectively. Body weight loss, breathing
noises with increasing severity towards the end of pre-pairing and throughout pairing until death were oberved.
- For all decedent animals dark red lungs and/or incompletely collapsed lungs were noted during necropsy.
Although the distribution of the deaths suggested a relationship to treatment the presence of bronchopneumonia, bronchiolitis/peribronchiolitis and/or fluid in the lungs was considered to provide strong evidence that death or moribund condition had, in all of the decedents, resulted from gavage error. - Body weight and weight changes:
- effects observed, treatment-related
- Description (incidence and severity):
- At 300 mg/kg bw/day, a slight treatment-related reduction in body weights and body weight gain were noted in males and females.
- Food consumption and compound intake (if feeding study):
- effects observed, treatment-related
- Description (incidence and severity):
- At 300 mg/kg bw/day, a slight treatment-related reduction in food consumption was noted in males and females.
- Food efficiency:
- not examined
- Water consumption and compound intake (if drinking water study):
- not examined
- Ophthalmological findings:
- no effects observed
- Haematological findings:
- no effects observed
- Clinical biochemistry findings:
- effects observed, treatment-related
- Description (incidence and severity):
- At 300 mg/kg bw/day, 3-fold higher alanine aminotransferase and slightly higher aspartate aminotransferase levels in males and approximately 2-fold higher alanine aminotransferase levels in females were recorded (not reaching statistical significance and still within the range of historical control data). These higher values deemed related to treatment, also in view of the changes in liver weights noted in males.
- Urinalysis findings:
- not examined
- Behaviour (functional findings):
- no effects observed
- Immunological findings:
- not examined
- Organ weight findings including organ / body weight ratios:
- effects observed, treatment-related
- Description (incidence and severity):
- In males at 300 mg/kg bw/day, statistically significantly lower absolute liver weights and their ratios to brain were recorded when compared with controls.
- Gross pathological findings:
- no effects observed
- Description (incidence and severity):
- There were no macroscopical findings that were deemed related to treatment with the test item.
- Neuropathological findings:
- not examined
- Histopathological findings: non-neoplastic:
- effects observed, treatment-related
- Description (incidence and severity):
- Histopathological changes considered to be associated with the administration of the test item were present in the mesenteric lymph nodes of females given 30 mg/kg bw/day and both sexes given 100 or 300 mg/kg bw/day.
- Histopathological findings: neoplastic:
- no effects observed
Effect levels
- Dose descriptor:
- NOAEL
- Effect level:
- 100 mg/kg bw/day (actual dose received)
- Based on:
- test mat.
- Sex:
- male/female
- Basis for effect level:
- body weight and weight gain
- clinical biochemistry
- clinical signs
- food consumption and compound intake
Target system / organ toxicity
- Critical effects observed:
- no
Applicant's summary and conclusion
- Conclusions:
- Based on these results, the NOAEL (No Observed Adverse Effect Level) for general toxicity was considered to be 100 mg/kg body weight/day based on clinical signs, reduced body weights and
food consumption, and increased serum ALAT- and ASAT activities at 300 mg/kg bw/day.
