Details on exposure:
PREPARATION OF DOSING SOLUTIONS:
The test item formulations were freshly prepared before dose administration on each treatment day. The required quantity of test item was weighed and triturated well in a mortar with a small quantity of vehicle until a homogenous suspension was formed and thereafter the entire quantity of the formulation was transferred into measuring cylinder. A small quantity of vehicle was added to rinse the mortar and this was transferred into the measuring cylinder. The rinsing procedure of mortar and pestle was repeated (many times) to ensure the transfer of the contents to the measuring cylinder. Finally, the volume was made up to required quantity with vehicle to get desired concentration of 10, 30 and 100 mg/mL of test item for low, mid and high dose groups respectively. The test formulations were maintained under stirring conditions using magnetic stirrer to maintain homogeneity of the test item formulations.

VEHICLE
- Justification for use and choice of vehicle (if other than water): The test item was in-soluble in distilled water and uniformly suspended in 0.5% w/v Carboxy Methyl Cellulose at the concentration of 100 mg/mL (the highest dose concentration selected for the study considering the dose volume of 10 mL/kg body weight) as per in-house solubility/suspendibility test results. Hence, 0.5% w/v Carboxy Methyl Cellulose was used as vehicle for test item formulations and the details were recorded in the raw data and presented in the study report.
- Concentration in vehicle: 10 - 100mg/mL
- Amount of vehicle (if gavage): 10mL/kg bw
- Lot/batch no. (if required): BCBN1690V
Details on mating procedure:
- M/F ratio per cage: 1:1
- Length of cohabitation: 2 weeks
- Proof of pregnancy: sperm in vaginal smear referred to as day 0 of pregnancy.
- After 14 days of unsuccessful pairing replacement of first male by another male with proven fertility.
- Further matings after two unsuccessful attempts: no
- After successful mating each pregnant female was caged (how): individually
- Any other deviations from standard protocol: No
Analytical verification of doses or concentrations:
no
Details on analytical verification of doses or concentrations:
The stability and homogeneity of the test item in dose formulations was not established under this dose range finding study. However, freshly prepared test item formulations were administered to the animals.
Duration of treatment / exposure:
Males: two weeks pre-mating, during mating and up to the day before sacrifice during post-mating period (total of 32 days of treatment).

Offspring viability indices:
See List below.
Clinical signs:
no effects observed
Dermal irritation (if dermal study):
not examined
Mortality:
no mortality observed
Body weight and weight changes:
effects observed, non-treatment-related
Description (incidence and severity):
A slight reduction in mean body weight and mean percent change in body
weight gain with respect to day 1 from group G4 males was noted during week 3 and 4. These noted changes are not considered as test item related, as there were no other systemic toxicity effects noted from this dose level in both sexes.

There were no changes noted in mean body weight and mean percent change in body weight gain during gestation or lactation period.
Food consumption and compound intake (if feeding study):
no effects observed
Food efficiency:
not examined
Water consumption and compound intake (if drinking water study):
not examined
Ophthalmological findings:
not examined
Haematological findings:
effects observed, non-treatment-related
Description (incidence and severity):
The following statistically significant changes were noted in haematology parameters of tested dose groups from both the sexes when compared with vehicle
control group:
- increase in mean prothrombin time of group G4 males;
- increase in mean activated prothrombin time of groups G2, G3 and G4 males;
- decrease in mean leucocyte (WBC) count of group G2 females;
- decrease in mean absolute lymphocytes of groups G2 and G3 females;
- decrease in mean absolute monocytes of group G2 females.

These noted changes are considered to be incidental and not test item-related, as these changes are lacking relevant dose dependency (except in case of activated prothrombin time) and the obtained values are still within lab historical control data range of same species and strain.
Clinical biochemistry findings:
effects observed, non-treatment-related
Description (incidence and severity):
A statistically significant increase in mean urea levels of group
G3 and G4 males compared with vehicle control group was noted. However, these increases are considered to be incidental and not test item-related, as the obtained values are within lab historical control data range of same species and strain.
Endocrine findings:
not examined
Urinalysis findings:
effects observed, non-treatment-related
Description (incidence and severity):
A statistically significant increase in mean pH levels of groups G2 and
G4 males compared with vehicle control group was noted. However these changes are considered to be incidental and not test item-related, as the obtained values are within lab historical control data range of same species and strain.
Behaviour (functional findings):
not examined
Immunological findings:
not examined
Organ weight findings including organ / body weight ratios:
effects observed, non-treatment-related
Histopathological findings: non-neoplastic:
not examined
Histopathological findings: neoplastic:
not examined
Other effects:
no effects observed
Reproductive function: oestrous cycle:
no effects observed
Description (incidence and severity):
There were no irregularities observed in the oestrus cyclicity of females from all the
tested dose groups and vehicle control group during pre-mating and mating treatment periods. The mean length (days) of oestrus cycle per female during pre-mating and mating treatment period was unaffected by the test item administration at any of the tested dose groups when compared with vehicle control group.
Reproductive function: sperm measures:
not examined
Reproductive performance:
effects observed, non-treatment-related
Description (incidence and severity):
A statistically significant increase in mean number of female pups born at birth
and mean survived number of females pups on LD 4, 7 and 13 from group G2 compared with vehicle control group was noted, however, these changes are considered to be incidental with no toxicological relevance.

A slight reduction in male fertility rate of groups G3 and G4 was noted. These noted changes are not considered as test item related, as there were no changes noted in mean organ weight of any of the reproductive organs and also no gross pathological changes noted in any of reproductive organs during conduct of necropsy.

A increase in post implantation losses from group G3 and G4 was noted. However these changes are not considered test item related, as a total of 3 dams were noted with post implantation loss from these dose groups with a maximum of 2 implantation loss and the obtained range of implantation loss is still within the lab historical control data of same species and strain.

Conclusions:
In a dose range finding study for a EOGRT study, the oral administration of the test item in Sprague Dawley rats did not produce any indication of systemic, reproduction and developmental toxicity at the dose levels of 100, 300 and 1000 mg/kg bw/d and the same are then considered appropriate for the definitive test.

Executive summary:

To establish doses for a definitive EOGRT study a dose range finding study non GLP was performed using Sprague Dawley Rats. Doses of 100mg/kg, 300mg/kg and 1000mg/kg were chosen in this study based on available toxicological data in the same substance. 10 male and 10 female rats were allocated to each dose group including a concurrent vehicle control group. Carboxy methyl cellulose was chosen as vehicle and the test item was applied via oral (gavage) once daily. The males were treated for two weeks pre-mating, during mating and up to the day before sacrifice during post-mating period (total of 32 days of treatment). The females were treated for two weeks pre-mating period, during mating, pregnancy (gestation) and up to lactation day 13 (total of 49 to 66 days of treatment). For systemic toxicity assessment, animals were observed for clinical signs, mortality and morbidity, body weight and feed consumption (including during gestation and lactation periods), clinical pathological examinations (haematology, clinical chemistry and urinalysis) and organ weighing. For reproductive toxicity assessment, males and dams were evaluated for reproductive performances such as, mating index, fertility index, gestation index, parturition index, pre-coital interval, gestation length, post-implantation loss and prenatal loss. At birth and during lactation, parameters such as, number of live/survived/dead pups, litter size, sex ratio and live birth/survival index per litter were observed. For F1 assessment, survived pups were observed once daily for external examinations and twice daily for mortalities till termination (postnatal day 13). All pups were weighed individually on PND 1, 4, 7 and 13. At termination, all the terminally sacrificed adults and pups were subject to detailed gross pathological examination with special emphasis towards reproductive organs. There were no treatment related effects observed for systemic, reproduction or developmental toxicity at the dose levels of 100, 300 and 1000 mg/kg bw/d. Based on these results, it is concluded that the same doses can be selected as low, mid and high doses for the subsequent Extended One-Generation Reproductive Toxicity Study.

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
CMC (carboxymethyl cellulose)
Remarks:
0.5% w/v Carboxy Methyl Cellulose
Details on exposure:
PREPARATION OF DOSING SOLUTIONS:
The test item formulations were prepared and administered to the animals within the established stability conditions. The required quantity of test item was weighed and triturated well in a mortar with a small quantity of vehicle until a homogenous suspension was formed and thereafter the entire quantity of the formulation was transferred into measuring cylinder. A small quantity of vehicle was added to rinse the mortar and this was transferred into the measuring cylinder. The rinsing procedure of mortar and pestle was repeated (many times) to ensure the transfer of the contents to the measuring cylinder. Finally, the volume was made up to required quantity with vehicle to get desired concentration of 10, 30 and 100 mg/mL of test item for low, mid and high dose groups respectively. The test formulations were maintained under stirring conditions using magnetic stirrer to maintain homogeneity of the test item formulations.

VEHICLE
- Justification for use and choice of vehicle (if other than water): The test item was insoluble in distilled water and uniformly suspended in 0.5% w/v Carboxy Methyl Cellulose at the concentration of 100 mg/mL (the highest dose concentration selected for the study considering the dose volume of 10 mL/kg body weight) as per laboratory solubility/suspendibility test results. Hence, 0.5% w/v Carboxy Methyl Cellulose was used as vehicle for test item formulations.
- Concentration in vehicle: 10 - 100mg/mL
- Amount of vehicle (if gavage): 10mL/kg bw
- Lot/batch no. (if required): BCBN1690V, SLCH1520
Details on mating procedure:
- M/F ratio per cage: 1:1
- Length of cohabitation: 2 weeks
- Proof of pregnancy: sperm in vaginal smear referred to as day 0 of pregnancy.
- If mating has not occurred after 2 weeks, the animals will be separated without further continuation of mating. If there are insufficient males (e.g. due to male death before pairing) then male(s) which have already mated will be paired with a second female(s).
- Further matings after two unsuccessful attempts: no
- After successful mating each pregnant female was caged (how): individually
- Any other deviations from standard protocol: No
Analytical verification of doses or concentrations:
yes
Details on analytical verification of doses or concentrations:
The stability of the test item in dose formulations was established in a preliminary study. The test item formulations were stable at room temperature for 6 hours and up to 48 hours at 2 to 8°C at the concentrations of 10 mg/mL and 500 mg/mL in 0.5% Carboxymethyl Cellulose. Prepared test item formulations were administered to the animals within established stability conditions.
Homogeneity and dose formulation analysis for dose concentration verification was done by a validated ICP-MS method (study nº BIO-ANM 1575). Sampling and analysis of formulations were performed on days 16/02/2021 (Week 1), 15/04/2021 (Week 9), 10/06/2021 (Week 17) and 03/09/2021 (Week 29). Samples were collected in duplicates from top, middle and bottom layers from low, mid and high dose concentrations and in duplicates from middle layer from vehicle control. Formulations were considered acceptable, as the mean results were within the range of 85 to 115% of the nominal concentration and the relative standard deviation (% RSD) was ≤10%.
Duration of treatment / exposure:
Parental males: 10 weeks during pre-mating period + 2 weeks during mating period until sacrifice during post-mating period (a total of 98 to 108 days).
Parental females: 10 weeks during pre-mating period + 2 weeks during mating period + throughout gestation and lactation periods up to weaning of F1 animals (a total of 113 to 127 days).

Results and discussion

Results: P0 (first parental generation)

General toxicity (P0)

Clinical signs:
no effects observed
Description (incidence and severity):
There were no clinical signs of toxicity noted in any of the tested dose group animals of both sexes throughout the experimental period.
Dermal irritation (if dermal study):
not examined
Mortality:
no mortality observed
Description (incidence):
There were no mortality/morbidity observed at any dose group during the experimental period.
Body weight and weight changes:
effects observed, non-treatment-related
Description (incidence and severity):
There were no changes noted in mean body weight and percent change in mean body weight gain with respect to day 1 in all the tested dose group males throughout the experimental period when compared with vehicle control group.

An incidental statistically significant decrease in mean percent change in body weight gain on day 7 with respect to day 1 in group G2 females was noted when compared with vehicle control group. This noted change is unrelated to treatment as there were no changes noted in mean body weight and mean feed consumption during this period. Also, the mean percent change in body weight gain throughout the experimental period in group G2 females was unaffected.

There was no test item related changes noted in mean body weight and percent change in mean body weight gain during gestation and lactation periods in all the tested dose groups when compared with vehicle control group. However, statistically significant increase in mean percent change in body weight gain during lactation day 1 to 4 in group G3 and during lactation day 7 to 14 in group G4 were noted when compared with vehicle control group. These noted differences are considered as incidental and unrelated to treatment as there were no such changes noted in mean body weight and mean feed consumption during these periods from both the dose levels.
Food consumption and compound intake (if feeding study):
effects observed, non-treatment-related
Description (incidence and severity):
There was no test item related changes noted in mean feed consumption in all tested dose groups for both sexes throughout the experimental period (including gestation and lactation periods for females) when compared with vehicle control group.

However, statistically significant decrease in mean feed consumption during week 1 in all tested dose group males was noted when compared with vehicle control group. These noted differences are considered as incidental and unrelated to treatment as there were no changes noted in mean body weight and mean percent change in mean body weight gain with respect to day 1 during this period from any of the dose levels.
Food efficiency:
not examined
Water consumption and compound intake (if drinking water study):
not examined
Ophthalmological findings:
not examined
Haematological findings:
effects observed, non-treatment-related
Description (incidence and severity):
Statistically significant decrease in mean total erythrocyte count in group G4 males, decrease in mean eosinophils (%) in groups G3 and G4 males and decrease in absolute neutrophils in groups G2 and G3 females were noted when compared with vehicle control group. These differences are considered as incidental and unrelated to treatment, as the obtained mean values are within laboratory historical control range of same species and strain and also similar changes were not occurred in other sex of same dose level.
Clinical biochemistry findings:
effects observed, non-treatment-related
Description (incidence and severity):
Statistically significant decrease in mean albumin levels in group G4 females was noted when compared with vehicle control group. This difference is considered as incidental and unrelated to treatment, as the obtained mean value is within laboratory historical control range of same species and strain and also similar changes were not occurred in other sex of same dose level.
Endocrine findings:
no effects observed
Description (incidence and severity):
There were no changes noted in estimated mean serum Thyroxine (T4) and Thyroxine Stimulating Hormone (TSH) levels in any of the tested dose groups of both sexes when compared with vehicle control group.
Urinalysis findings:
effects observed, non-treatment-related
Description (incidence and severity):
Statistically significant increase in mean specific gravity of urine in group G4 females was noted when compared with vehicle control group. This difference is considered as incidental and unrelated to treatment, as the obtained mean value is within laboratory historical control range of same species and strain and also similar changes were not occurred in other sex of same dose level.
Behaviour (functional findings):
not examined
Immunological findings:
not examined
Organ weight findings including organ / body weight ratios:
effects observed, non-treatment-related
Histopathological findings: non-neoplastic:
effects observed, non-treatment-related
Description (incidence and severity):
There was no test item-related histopathological findings in high dose parental animals.

Few of the microscopic findings observed in this study such as ultimobranchial cyst(s) in thyroid gland, epithelial cyst(s)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.

Quantitative ovarian follicular assessment (primordial and primary follicles) in all parental females of control and high dose groups did not reveal any test item related variations.
Histopathological findings: neoplastic:
no effects observed
Other effects:
no effects observed

Reproductive function / performance (P0)

Reproductive function: oestrous cycle:
effects observed, non-treatment-related
Description (incidence and severity):
A total of 3, 3, 2 and 1 female(s) were noted with single irregular oestrus cycle from groups G1, G2, G3 and G4, respectively. These occurrences are considered as incidental and unrelated to treatment exposure as the same animals were proceeded or preceded by normal cycles.
Reproductive function: sperm measures:
effects observed, non-treatment-related
Description (incidence and severity):
Sperm motility(%): There were no changes noted in mean sperm motility (%) in all the tested dose groups when compared with vehicle control group.
Sperm Morphology: There were no test item-related changes noted in sperm morphologies in all the tested dose groups when compared with vehicle control group. The noted sporadic statistically significant differences in sperm morphology such as increase in head anomalies in group G3, decrease in tail anomalies in groups G3 and G4, increase in multiple anomalies in group G4 and increase in total sperms with anomalies in group G4 when compared with vehicle control group, are considered as toxicologically irrelevant.
Spermatid Head Count and Daily Sperm Production: There were no test item-related changes noted in mean spermatid head count or daily testicular sperm production per animal in any of the tested dose groups when compared with the vehicle control group. The noted statistically significant increase in mean spermatid head count in group G4 when compared with vehicle control group is considered as toxicologically irrelevant.

Nipple retention in male pups:
no effects observed
Description (incidence and severity):
F1 pups: There were no occurrences or evidences of retention of nipples in any of the male pups examined on the postnatal day 13 from all the tested dose groups and vehicle control group litters.
Organ weight findings including organ / body weight ratios:
effects observed, non-treatment-related
Description (incidence and severity):
F1 surplus pups: a statistically significant decrease in mean absolute thymus weight was noted in group G4 when compared with vehicle control group. This change is considered as incidental and unrelated to treatment, as the obtained mean value is within laboratory historical control range of PND 21 pups of same species and strain and also no gross pathological changes were noted in any of the pups at this dose level.
Cohort 1A: A statistically significant decrease in mean spleen weight (absolute and relative) in group G3-C1A males, increase in mean relative prostate weight in groups G3-C1A and G4-C1A males, increase in mean relative pituitary weight in all tested dose group males, increase in mean relative thyroid weight in group G4-C1A males, decrease in mean absolute spleen weight in groups G3-C1A and G4-C1A females, decrease in mean absolute ovaries weight in group G3-C1A, increase in mean absolute kidneys weight in group G2-C1A females, decrease in mean relative spleen and ovaries weight in group G3-C1A females and increase in mean relative heart weight in group G4-C1A females were noted when compared with vehicle control group.
These noted differences are considered as incidental and unrelated to treatment, as the obtained mean values are within laboratory historical control range of same species and strain and also neither gross pathological functional changes nor microscopic changes were noted in any of these organs in all the tested dose group animals.
Cohort 1B: There were no test item-related changes noted in mean absolute and relative organ weights in all the tested dose groups of both sexes when compared with vehicle control group. The noted statistically significant differences in some of the organs/tissues from all the tested dose groups of both sexes are not considered as adverse as the obtained mean values are within laboratory historical control range of same species and strain and also gross pathological examination did not reveal any changes in any of organs/tissues in all the tested dose group animals.
Gross pathological findings:
no effects observed
Description (incidence and severity):
There were no gross pathological changes/findings noted in any of the tested dose group and vehicle control group of F1 generation animals of both sexes during the necropsy.
Histopathological findings:
effects observed, non-treatment-related
Description (incidence and severity):
There was no test item-related histopathological findings in high dose C1A animals.

Few of the microscopic findings observed in this study such as ultimobranchial cyst(s) in thyroid gland, epithelial cyst(s)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.

Quantitative ovarian follicular assessment (primordial and primary follicles) in all C1A females of control and high dose groups did not reveal any test item related variations. Similarly, quantitative evaluation of corpora luteal count in C1A females of control and high dose group did not reveal any test item related variations.
Other effects:
effects observed, non-treatment-related
Description (incidence and severity):
F1 pups:
Postnatal Developmental Landmarks: There were no changes noted in mean occurrences of postnatal developmental landmarks of F1 pups such as pinna unfold, fur development, incisor eruption, eye opening and testes descent evaluated during postnatal period in all the tested dose groups when compared with vehicle control group.
Sensory Reflexes: There were no changes noted in mean responses of sensory reflexes of F1 pups such as surface righting, auditory startle and air righting performed during postnatal period in all the tested dose groups when compared with vehicle control group.
Thyroid Hormone Levels (T4 and TSH):
There were no changes noted in mean T4 levels of PND 4 pups per litter in all the tested dose groups when compared with the vehicle control group.
There was no test item related changes noted in meanT4 and TSH levels of PND 21 pups per litter in all the tested dose groups when compared with the vehicle control group. The noted statistically significant increase in mean serum T4 levels in all the tested dose groups of PND 21 pups is considered as incidental and also the obtained mean values are within laboratory historical control range of same species and strain.

Cohort 1A:
Thyroid Hormone Levels (T4 and TSH): A statistically significant increase in serum T4 levels in group G4-C1A females and decrease in mean TSH levels were noted in all the tested dose group males when compared with vehicle control group. These differences are considered as incidental and unrelated to treatment, as the obtained mean values are within laboratory historical control range of same species and strain and also similar changes were not occurred in other sex of same dose level.
Splenic Lymphocyte Sub-populations: There was no test item related changes noted in mean splenic sub-populations of T "helper" (CD4+) cells, T cytotoxic (CD8+) cells, natural killer (NK) cells and B lymphocytes in any of the tested dose groups of both sexes when compared with vehicle control group. However, statistically significant increase in mean T "helper" (CD4+) cells populations in group G3-C1A females and statistically significant decrease in mean T cytotoxic (CD8+) cells populations in groups G2-C1A and G3-C1A females were noted when compared with vehicle control group. These differences are considered as incidental and unrelated to treatment, as the obtained mean value is within laboratory historical control range of same species and strain.
Sperm Motility (%): There were no changes noted in mean sperm motility (%)in all the tested dose groups when compared with vehicle control group.
Sperm Morphology: There were no test item-related changes noted in sperm morphology in all the tested dose groups when compared with vehicle control group. The noted sporadic statistically significant differences in sperm morphology such as increase in head anomalies in group G2-C1A, increase in neck anomalies in group G3-C1A and decrease in multiple anomalies in group G3-C1A and increase in total sperms with anomalies in group G3-C1A when compared with vehicle control group are considered as toxicologically irrelevant.
Spermatid Head Count and Daily Sperm Production: There were no changes noted in mean spermatid head count or daily testicular sperm production per animal in any of the tested dose groups when compared with the vehicle control group.
Oestrus Cycle Evaluation: a total of 2, 2, 1 and 1 female(s) were noted with single irregular oestrus cycle from groups G1-C1A, G2-C1A, G3-C1A and G4-C1A, respectively. These occurrences are considered as incidental and unrelated to treatment exposure as the same animals were proceeded or preceded by normal cycles.

Applicant's summary and conclusion

Conclusions:
In an Extended One-Generation Reproductive Toxicity study (EOGRTS) performed orally in Sprague Dawley rats, the NOAEL of the test substance was determined to be 1000 mg/kg bw/day for systemic, reproduction and developmental toxicity.

Executive summary:

An Extended One-Generation Reproductive Toxicity study (EOGRTS) was conducted in rats by oral administration of the test substance in accordance with OECD test guideline 433, following the GLP principles. A total of 200 (100 males + 100 females) Sprague Dawley rats were selected for parental (P) generation and distributed to four main groups. Each P generation group (G1, G2, G3 and G4) consisted of 25 males and 25 females. A total of 160 males and 160 females were selected on the day of weaning (PND21) and randomly assigned to two cohorts (Cohort 1A and Cohort 1B). Each cohort consisted of four groups of 20 males and 20 females per group. The animals in G1 (P generation)/G1-C1A/G1-C1B (F1 generation) groups were administered with vehicle (0.5% carboxymethyl cellulose), the animals in G2 (P generation)/G2-C1A/G2-C1B (F1 generation), G3 (P generation)/G3-C1A/G3-C1B (F1 generation), and G4 (P generation)/G4-C1A/G4-C1B (F1 generation) groups were administered with the test item at the dose levels of 100, 300 and 1000 mg/kg bw/day respectively based on the results of a dose range finding study for which no adverse effects were found up to the dose of 1000 mg/kg/day.. The vehicle and test item formulations were administered orally by gavage at the dose volume of 10 mL/kg bw. Homogeneity and dose formulation analysis for dose concentration verification was performed during weeks 1, 9, 17 and 29 of the treatment period and the mean results were within the range 85-115% recovery to the nominal concentration and RSD was less than 10%.


P generation animals were administered with test item 10 weeks during pre-mating and 2 weeks during mating. Parental males were dosed until sacrifice during post-mating period (a total of 98 to 108 days) and parental females were dosed throughout gestation and lactation periods up to weaning of F1 animals (a total of 113 to 127 days). Cohort 1A animals were dosed from day of weaning (PND21) to PND 91 (13-weeks age) and cohort 1B animals from day of weaning (PND21) to PND 98 (14-weeks age).


For all P generation animals the following observations were performed: clinical signs once daily, mortality/morbidity twice daily and detailed clinical examination weekly; body weights (throughout the experimental period) and feed consumption (throughout the experimental period, except during cohabitation period) once weekly; haematology, clinical chemistry, urinalysis and thyroid hormone (T4 and TSH) levels; Sperm parameters (motility, morphology and daily sperm production) for all P males; Oestrus cyclicity evaluation pre-mating and cohabitation period for all P females. The body weights and feed consumption was recorded during gestation (Gestation Day 0, 7, 14 and 20) and during lactation (Lactation Day 1, 4, 7, 14 and 21) for all P females. The gross pathology and organ weighing was performed on the day of termination for all P animals. Histopathological examination was conducted on all the tissues collected from the P generation vehicle control and high dose group animals. All P males and females were evaluated for reproductive performance or indices such as, mating and fertility index (for P males and females) and pre-coital interval, gestation length, fecundity index, gestation index, post-implantation loss and postnatal loss (for P females). All P females were observed for birth parameters (number of live/dead pups born, litter size, sex ratio, and live birth index per litter) and for litter observations (number of live/dead pups during lactation period, sex ratio and pup survival index per litter).


All P males and females did not reveal any test item related changes in systemic and reproductive endpoints in any of the tested dose groups.


The F1 generation pups were observed once daily for external examinations and twice daily for mortalities till termination, weighed individually on postnatal day (PND) 1, 4, 7, 14 and 21, observed for occurrences of postnatal developmental landmarks, observed for responses towards to sensory reflexes during postnatal period, measured for anogenital distance on PND 4, observed for retention of any nipples/areolae in male pups on PND 13 and observed for gross pathological observations at termination. Also, assessment for T4 levels was conducted for PND 4 pups and assessment for T4 and TSH levels was conducted for PND 21 pups.


All F1 pups of both sexes did not reveal any test item related changes in growth parameters, postnatal developmental landmarks, sensory reflexes, thyroid hormone levels and no gross pathological changes were noted at any of the tested dose group litters.


For all Cohort 1A (F1 generation) animals the following observations were performed: clinical signs once daily, mortality/morbidity twice daily and detailed clinical examination weekly once; body weights and feed consumption once weekly; occurrence of sexual maturation (for balano-preputial separation in C1A males and for vaginal patency in C1A females); mean occurrence of first cornified cells and time interval between vaginal patency and occurrence of first cornified cells in C1A females; oestrus cyclicity during PND 75 to 88 in C1A females; haematology, clinical chemistry, urinalysis and thyroid hormone (T4 and TSH) levels; Sperm parameters (motility, morphology and daily sperm production) in all C1A males. The gross pathology and organ weighing were performed on the day of termination for all C1A animals. Histopathological examination was conducted on all the tissues collected from the C1A vehicle control and high dose group animals. The flow cytometric analysis of splenic samples for assessment of splenic lymphocyte sub-populations of T "helper" (CD4+) cells, T cytotoxic (CD8+) cells, natural killer (NK) cells and B lymphocytes was conducted for randomly selected males and females from each C1A group.


All C1A males and females did not reveal any test item related changes in systemic and reproductive endpoints in any of the tested dose groups when compared with vehicle control group, except slight reduction in mean body weight and percent change in mean body weight gain in all tested dose group males. There were no changes noted in sub-population of splenic lymphocytes such as, T "helper" (CD4+) cells, T cytotoxic (CD8+) cells, natural killer (NK) cells and B lymphocytes at any of the tested dose groups when compared with vehicle control group.


For all Cohort 1B (F1 generation) animals the following observations were performed: clinical signs once daily, mortality/morbidity twice daily and detailed clinical examination weekly once; body weights and feed consumption once weekly; occurrence of sexual maturation (for balano-preputial separation in C1B males and for vaginal patency in C1B females) and gross pathology and organ weighing for all C1B animals.


All C1B males and females did not reveal any test item related changes in systemic and reproductive endpoints, except reduction in mean body weight and percent change in mean body weight gain in all tested dose group of both sexes.


Therefore, based on the above results, the NOAEL of the test substance is considered to be 1000 mg/kg bw/day for systemic, reproduction and developmental toxicity.
