Statistics:
After verification, the data was subjected to statistical analysis using SPSS software version 22. Body weight, body weight gain (percent change in body weight with respect to Day 1 body weight), feed consumption, organ weights and ratios, haematological and clinical chemistry estimations and urine analysis parameters (urobilinogen, pH, specific gravity and urine volume), FOB parameters (rearing, urination, defecation, excessive grooming, body temperature, grip strength, motor activity and hind limb foot splay) were subjected to statistical analysis. One-way ANOVA followed by Dunnett’s post test was done for different treatment groups comparing with the control group data.
Clinical signs:
no effects observed
Mortality:
no mortality observed
Body weight and weight changes:
effects observed, non-treatment-related
Description (incidence and severity):
However, statistically significant higher body weight gain (percent change in body weight with respect to Day 1) were observed during days 1-8, 1-22, 1-28 to 1-42 (G4RF). In the absence of associated variation in feed consumption, the noted variations are considered incidental
Food consumption and compound intake (if feeding study):
no effects observed
Ophthalmological findings:
no effects observed
Haematological findings:
effects observed, non-treatment-related
Description (incidence and severity):
In main group, statistically significant decrease in red blood cells in G4 (-10.11%) in males; in females, increase in Mean platelet volume in G4 (+10.4%) and decrease in haematocrit value in G3 (-8.42%) was noted. These changes are considered as incidental in the absence of dose responsiveness and also because of the minimal magnitude.
In recovery groups, statistically significant increase in white blood cells G4RM
(-40.9%) and increase in APTT in G4RF (+9.2%) and decrease in percent monocytes in G4RF (-20.65%), absolute monocytes in G4RF (-39.05%) and absolute basophils in G4RF (-64.6%) was noted. Variations noted in few differential leukocyte counts in recovery females was not associated with any changes in WBC. All other changes noted are considered as incidental and not related to test item in the absence of such changes at the end of treatment period and also, all the changes could be due to random biological variation
Clinical biochemistry findings:
effects observed, non-treatment-related
Description (incidence and severity):
In main group, increase in total bilirubin in G4 (+157.1%), phosphorous in G4 (+16.4%) and potassium in G4 (+23.8%) in males; in females, increase in total cholesterol in G4 (+36.3%), calcium in G4 (+9.60%) and decrease in chloride in G2
(-2.7%) were noted. The increase in total bilirubin in G4 male was not associated with any microscopic changes in kidneys. All other changes noted are considered incidental in the absence of dose responsiveness and also, all the values were within the historical range of the species.
In recovery group males, decrease in total protein (-5.9%), and glucose (-7.9%), and increase in Phosphorous (+5.44%) was noted. All these changes are considered as incidental because of their minimal magnitude and also absence of such changes at the end of treatment period or in other sex-recovery females
Urinalysis findings:
effects observed, non-treatment-related
Description (incidence and severity):
However the statistically significant increase in specific gravity in G4M and decrease in pH in G4M and in females decrease in urine volume was noted in G4F. The noted variations are considered incidental and not related to test item in the absence of dose responsiveness
Behaviour (functional findings):
effects observed, non-treatment-related
Description (incidence and severity):
No test item related changes were observed in neurological/functional examination test in any of the test item treated groups. However there was decreased average hind limb grip strength in recovery groups of either sex in G4R.
The decrease in hind limb grip strength in G4R is considered to be incidental in the absence of variations in any of the other neuro-muscular parameters assessed
Organ weight findings including organ / body weight ratios:
effects observed, non-treatment-related
Description (incidence and severity):
No adverse test item related changes in fasting body weights, organ weights (absolute and relative) were noted. However, the following statistically significant changes were noted in organ weights and its ratios.
Increase in absolute weight of spleen in G4M, decrease in relative weights of kidney in G3M, G4M and liver in G4M; increase in absolute weight of thymus in G3F, spleen in G3F and brain in G2F was noted. In recovery groups, decrease in relative weight of ovaries in G4RF was noted.
Increase in spleen weight is considered incidental in the absence of dose responsiveness and without any associated macroscopic and microscopic changes in spleen
Gross pathological findings:
effects observed, treatment-related
Description (incidence and severity):
Grossly, test item-related, thickening of non-glandular region of stomach was observed in high dose rats (G4, Male: 5/5; Female: 5/5) and was microscopically correlated to hyperplasia of squamous cells in non-glandular stomach
Histopathological findings: non-neoplastic:

G: Group; - : No incidence
In non-glandular region of stomach, minimal to marked, diffuse hyperplasia of squamous cell was observed from low dose group of male rats and from mid dose group of female rats. Histologically, it was characterized by proliferation and thickening of stratum spinosum layer comprising of squamous epithelium with occasional increased keratin. Similar changes were also observed in recovery high dose group of rats but with decreased severity (minimal to moderate) and reduced incidences (3/5) indicating a trend towards recovery. Considering the recovery trend, magnitude of severity of lesion and relevance of this change to humans, this finding could be considered as non-adverse at 250 mg/kg body weight/day dose level (Nolte T et.al., 2016).
Few microscopic findings observed in this study such as ultimobranchial cyst in thyroid, epithelial cysts in thymus and all other findings were considered incidental as they occurred randomly across the dose groups including concurrent controls and/or were expected for laboratory rats of this age

Conclusions:
Based on the results discussed, the No Observed Adverse Effect Level (NOAEL) of the test item, Cyclic Glucamide C12-C14 was found to be 250 mg/kg body weight/day, (mid dose) when administered for a period of 28 consecutive days repeatedly by oral (gavage) route to Sprague Dawley rats under the experimental conditions and the doses employed.
Executive summary:

 


The objective of this study was to assess the toxic potential of the test itemCyclic Glucamide C12-C14when administered for a period of 28 consecutive days repeatedly by oral (gavage) to Sprague Dawley rats. This studyprovidesinformation on major toxic effects, target organs, possibility of cumulative effects and also the reversibility of effects (after 14 days recovery period) and an estimate of the No Observed Adverse Effect Level (NOAEL).


A total of60Sprague Dawley rats (30males +30females) were distributed to4main(G1, G2, G3 & G4)and2recovery groups(G1R & G4R). Each group consisted of                       5 rats/sex. Theratsallocated to groups G2, G3 and G4/G4R were administeredwith testitem,Cyclic Glucamide C12-C14at the doses of100,250and500mg/kg body weight/dayrespectively andG1/G1Rgroup animals received vehicle(distilled water)alone. The vehicle/test item formulations were administered byoral (gavage) routeat an equivolume of 10 mL/kgbody weight.


The test item formulations at the concentrations of 5 mg/mL and 50 mg/mLwere stable up to 48 hours at room temperature.Formulation analysis fordoseconcentration verification was performed for all the dose formulations prior to first treatment and during week 4 of the study.The dose formulation samples of Cyclic Glucamide C12-C14wereanalyzed for dose concentration analysis byUV-Vis methodand the results were found to be within the range ± 10% recovery to the nominal concentration with ˂10% RSD.


All theratswere observed once daily for clinical signs and twice daily for mortality and morbidity, weekly for detailed clinical examination, body weight and feed consumption; ophthalmoscopic examination was performed during acclimatizationperiodfor all the ratsand duringweek 4 ofdosingperiod for G1 and G4groups and duringweek 6 for G1R and G4R groups. Functional observational battery was performed during week 4 ofdosingperiod for G1and G4groups and duringweek 6 for G1Rand G4R groups.


At the end oftreatmentand recovery period, i.e., Day 29 andDay43, respectively, blood and urine sampleswerecollected and analyzed from overnight fastedrats. Subsequently, theratswere sacrificed using CO2asphyxiationfollowed by exsanguinationand subjected to gross pathological examination. Thestudy plan specified organs/tissueswere collected, weighedand preserved for histopathological examination.Histopathology examination was performed on organs of vehicle control and high dose group (G1 and G4).


No mortality and clinical signswere noted up to mid dose (250 mg/kg/day) group.However, ‘wetness around oral region after dose administration (approximately within 5 to 10 minutes post treatment) and found dried later during evening observation’ was observed in G4/G4R(high-dose-500 mg/kg/day) treated group of either sex from day 04 until the end of treatment period and was found normal during recovery period. The wetness could be secondary due to irritant nature of administration of test item which is evident from thehistopathology changesin stomachand considered adverse.


Notest item-related changes in body weight, percent change in body weight and feed consumptionwere observedthroughout the experimental period. Notest item-related neurological/functional abnormalitiesand no ocular changes were observed during examination. 


No toxicologically significant changes were noted in haematology, coagulation, clinical chemistry and urinalysis parameters.There were no test item-related effects inabsolute and relative organ weightsin all the tested dose groups in both the sexes.


Grossly, test item-related, thickening of non-glandular region of stomach was observed in high dose rats (G4, Male: 5/5; Female: 5/5) and was microscopically correlated to hyperplasia of squamous cells in non-glandular stomach.


Microscopically, test item-related changes were observed in non-glandular region of stomach and the incidences are as follows.

In non-glandular region of stomach, minimal to marked, diffuse hyperplasia of squamous cell was observed from low dose group of male rats and from mid dose group of female rats. Histologically, itwas characterized by proliferation and thickening ofstratum spinosumlayer comprising of squamous epithelium with occasional increased keratin. Similar changes were also observed in recovery high dose group of rats but with decreased severity (minimal to moderate) and reduced incidences (3/5) indicating a trend towards recovery. Considering the recovery trend, magnitude of severity of lesion and relevance of this change to humans, this finding could be considered as non-adverse at 250 mg/kg body weight/day dose level (Nolte Tet.al.,2016)

Additional information

Justification for classification or non-classification

Based on the results from the available repeated dose toxicity data and given that no human relevance is deducible from the effects on the forestomach seen in rats, it is concluded that the registration substance is not subject to classification and labelling according to the criteria of GHS and /or EU CLP.
