Description of key information

Reproductive toxicity study

Based on the data available from different studies, NOAEL for test chemicalwas considered to be in range of 1000-1500mg/kg bw/day .When male and female rats were treated with test chemiclorally. Thus, comparing this value with the criteria ofCLP regulation test chemicalisnot likely to classify as reproductive toxicant.

Conclusions:
NOAEL was considered to be 1500 mg/kg/day for P and F1 generation when CD Sprague-Dawley female rats treated with test material orally by gavage for 14 days.
Executive summary:

In a Teratogenic Potential Test, CD Sprague-Dawley female rats treated with test material in the concentration of 0, 100, 500 or 1500 mg/kg bw orally by gavage in water for 14 days (days 6-19 of gestation). Six rats died during the dosing period at 1500 mg/kg bw as compared to control. Survival was 100% in the controls and the groups receiving 100 and 500 mg/kg of dye. Slight reductions in body-weight gains at 1500 mg/kg bw and Orange discoloration of the urine was noted in all treated rats during the treatment period. No effect on reproductive parameters such as Viable and non-viable fetuses, early and late resorptions, total implantations and corpora lutea and sex ratio of fetuses were observed in treated female rats as compared to control. Green discoloration of the amniotic fluid was observed in 1, 10 and 16 rats at 100, 500 and 1500 mg/kg/day groups, respectively, and the small intestines were green in colour in many rats at 500 mg/Kg group. In addition, No effect on Body weight of fetuses were observed as compared to control. A slight increase in the number of litters with unossified sternebrae (sternebrae nos 1-6) and rudimentary 14th rib(s) was observed at 1500 mg/kg bw however, these values fell within the ranges of historical control data. No biologically meaningful or statistically significant differences in the number of litters and number of fetuses with malformations and number of fetuses or litters with developmental variations were observed in treated rats as compared to control. Therefore, NOAEL was considered to be 1500 mg/kg/day for P and F1 generation when CD Sprague-Dawley female rats treated with test material orally by gavage for 14 days.

Executive summary:

The teratogenic toxicity study was performed according to OECD 414guideline. Thepregnantfemale wistarratswere treated with test material in dose concentration 0,100,300,1000mg/kg bw /day by oral gavage route fromday 6 through day 17 post coitum.22 pregnantfemale /dose group werereceived test material while a group of 22 pregnant rats received the vehicle only (bi-distilled water containing 1% carboxymethylcellulose sodium salt) and served as a control group. Animals were checked twice daily for mortality/morbidity, and once daily for clinical signs. Food consumption and body weight were recorded at designated intervals during pregnancy. On day 21 post coitum, the animals were killed and examined macroscopically. Foetuses were removed by Caesarean section. All animals survived until Caesarean section and with the exception of violet discoloured urine, faeces and bedding material observed in all dosage groups, no reaction to treatment or clinical signs were observed in any female. Food consumption and body weighty development were not affected by the test material administration. No abnormal macroscopically findings were noted during necropsy. The differences amongst the relevant reproduction data (post-implantation loss, number of implantations and foetuses) of the vehicle control group and the dose groups gave no indication of test article related effects. The mean body weights of foetuses, the ratio of male and female foetuses and the results of external, visceral and skeletal examinations of foetuses gave no indication of effects caused by administration of the test material. Hence NOAEL was considered to be 1000 mg/kg body weight /day for F0 and F1 generation female wistar rats were treated withtest material orally.

Conclusions:
The No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity is considered to be 1000 mg/Kg/day. When male and female Crl:CD (SD) were treated with test material orally.
Executive summary:

Combined repeated dose and reproduction / developmental screening was performed to evaluate the toxic nature of test material . Male and female Crl:CD (SD) were used in the study. The test compound was dissolved in water and used at dose levels of 0, 40, 200 or 1000 mg/Kg/day. The male rats were treated for 42 days and female rats were treated for 41-47 days. Recovery group of 0 and 1000 mg/Kg/day was also included in the study. The treated animals were noted for clinical signs, functional battery observations, body weight, food consumption, urinalysis, haematology, blood chemistry, organ weight changes and histopathology reproductive and developmental parameters.

No adverse effect of the compound was observed at any dose level on the reproductive performances, such as the estrous cycle, copulation index, fertility index, or pairing days until copulation. No significant changes were observed in gestation length, delivery or lactation. All pregnant females delivered live pups. No adverse effect of the compound was observed on the developmental performances, such as the number of corpora lutea or implantations, implantation index, number of pups born or live pups, delivery index, birth index, live birth index, sex ratio or body weight on day 0 of lactation, or viability index or body weight on day 4 of lactation. Neither external abnormality nor macroscopic finding was detected in any pups at the necropsy. No adverse effects were noted in the various parameters studied. Based on the observations made,The No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity is considered to be 1000 mg/Kg/day. When male and femaleCrl:CD (SD)were treated with test material orally.

Additional information

Reproductive toxicity study:

Data available from different studies were reviewed to determine the reproductive toxicity of test chemical.The studies are as mentioned below:

1.Due to COVID-19, the study is delayed and the related information is expected to be provided by 15 March 2023. Please also refer to the attachment.

2.In a Teratogenic Potential Test, CD Sprague-Dawley female rats treated with test material in the concentration of 0, 100, 500 or 1500 mg/kg bw orally by gavage in water for 14 days (days 6-19 of gestation). Six rats died during the dosing period at 1500 mg/kg bw as compared to control. Survival was 100% in the controls and the groups receiving 100 and 500 mg/kg of dye. Slight reductions in body-weight gains at 1500 mg/kg bw and Orange discoloration of the urine was noted in all treated rats during the treatment period. No effect on reproductive parameters such as Viable and non-viable fetuses, early and late resorptions, total implantations and corpora lutea and sex ratio of fetuses were observed in treated female rats as compared to control. Green discoloration of the amniotic fluid was observed in 1, 10 and 16 rats at 100, 500 and 1500 mg/kg/day groups, respectively, and the small intestines were green in colour in many rats at 500 mg/Kg group. In addition, No effect on Body weight of fetuses were observed as compared to control. A slight increase in the number of litters with unossified sternebrae (sternebrae nos 1-6) and rudimentary 14th rib(s) was observed at 1500 mg/kg bw however, these values fell within the ranges of historical control data. No biologically meaningful or statistically significant differences in the number of litters and number of fetuses with malformations and number of fetuses or litters with developmental variations were observed in treated rats as compared to control. Therefore, NOAEL was considered to be 1500 mg/kg/day for P and F1 generation when CD Sprague-Dawley female rats treated with test material orally by gavage for 14 days. 

 

3.The teratogenic toxicity study was performed according toOECD 414guideline. Thepregnantfemale wistarratswere treated with test material in dose concentration 0,100,300,1000mg/kg bw /day by oral gavage route fromday 6 through day 17 post coitum.22 pregnantfemale /dose group werereceived test material while a group of 22 pregnant rats received the vehicle only (bi-distilled water containing 1% carboxymethylcellulose sodium salt) and served as a control group. Animals were checked twice daily for mortality/morbidity, and once daily for clinical signs. Food consumption and body weight were recorded at designated intervals during pregnancy. On day 21 post coitum, the animals were killed and examined macroscopically. Foetuses were removed by Caesarean section.All animals survived until Caesarean section and with the exception of violet discoloured urine, faeces and bedding material observed in all dosage groups, no reaction to treatment or clinical signs were observed in any female. Food consumption and body weighty development were not affected by the test material administration. No abnormal macroscopically findings were noted during necropsy. The differences amongst the relevant reproduction data (post-implantation loss, number of implantations and foetuses) of the vehicle control group and the dose groups gave no indication of test article related effects. The mean body weights of foetuses, the ratio of male and female foetuses and the results of external, visceral and skeletal examinations of foetuses gave no indication of effects caused by administration of the test material. HenceNOAEL was considered to be 1000 mg/kg body weight /day for F0 and F1 generation female wistar rats were treated withtest material orally.

 

4. Combined repeated dose and reproduction / developmental screening was performed to evaluate the toxic nature of test material . Male and female Crl:CD (SD) were used in the study. The test compound was dissolved in water and used at dose levels of 0, 40, 200 or 1000 mg/Kg/day. The male rats were treated for 42 days and female rats were treated for 41-47 days. Recovery group of 0 and 1000 mg/Kg/day was also included in the study. The treated animals were noted for clinical signs, functional battery observations, body weight, food consumption, urinalysis, haematology, blood chemistry, organ weight changes and histopathology reproductive and developmental parameters.

No adverse effect of the compound was observed at any dose level on the reproductive performances, such as the estrous cycle, copulation index, fertility index, or pairing days until copulation. No significant changes were observed in gestation length, delivery or lactation. All pregnant females delivered live pups. No adverse effect of the compound was observed on the developmental performances, such as the number of corpora lutea or implantations, implantation index, number of pups born or live pups, delivery index, birth index, live birth index, sex ratio or body weight on day 0 of lactation, or viability index or body weight on day 4 of lactation. Neither external abnormality nor macroscopic finding was detected in any pups at the necropsy.No adverse effects were noted in the various parameters studied. Based on the observations made,The No Observed Adverse Effect Level (NOAEL) for reproductive and developmental toxicity is considered to be 1000 mg/Kg/day. When male and femaleCrl:CD (SD)were treated with test material orally.

 

Hence the test chemical is not likely to classify as a reproductive toxicant as per the criteria mentioned in CLP regulation.

Effects on developmental toxicity

Description of key information

Developmental toxicity study

The data available for test chemical was reviewed to determine the developmental toxicity. No Observed Adverse Effect Level (NOAEL) for developmental toxicity was considered to be in range of 1000 -1500 mg/kg bw /day, when female rats were treated with test chemical orally.Thus, comparing this value with the criteria of CLP regulation test chemical is not likely to classify as reproductive and developmental toxicant.

Executive summary:

Data available from different studies were reviewed to determine thedevelopmental toxicity of  test chemical .The studies are as mentioned below:

Study 1.

The teratogenic toxicity study was performed according to OECD 414 guideline. The pregnant female wistar ratswere treated with test material in dose concentration 0,100,300,1000mg/kg bw /day by oral gavage route fromday 6 through day 17 post coitum.22 pregnantfemale /dose group werereceived test material while a group of 22 pregnant rats received the vehicle only (bi-distilled water containing 1% carboxymethylcellulose sodium salt) and served as a control group. Animals were checked twice daily for mortality/morbidity, and once daily for clinical signs. Food consumption and body weight were recorded at designated intervals during pregnancy. On day 21 post coitum, the animals were killed and examined macroscopically. Foetuses were removed by Caesarean section.

 All animals survived until Caesarean section and with the exception of violet discoloured urine, faeces and bedding material observed in all dosage groups, no reaction to treatment or clinical signs were observed in any female. Food consumption and body weighty development were not affected by the test material administration. No abnormal macroscopically findings were noted during necropsy. The differences amongst the relevant reproduction data (post-implantation loss, number of implantations and foetuses) of the vehicle control group and the dose groups gave no indication of test article related effects. The mean body weights of foetuses, the ratio of male and female foetuses and the results of external, visceral and skeletal examinations of foetuses gave no indication of effects caused by administration of the test material. Hence NOAEL was considered to be 1000 mg/kg body weight /day for F0 and F1 generation female wistar rats were treated with test material orally.

Study 2.

In a Teratogenic toxicity study, CD Sprague-Dawley female rats were treated with test material in the concentration of 0, 100, 500 and 1500 mg/kg body weight/day by oral gavage. Six rats died during the dosing period and at 1500 mg/kg bw/day and Orange discoloration of the urine was observed in all the treated rats as compared to control. Similarly, green discoloration of the amniotic fluid and green colored small intestines were observed at 1500 mg/kg bw/day and green discoloration of the amniotic fluid was observed at 100 and 500 mg/kg bw/day treated rats as compared to control. No effect on Post-implantation loss/dam, Total implantations/dam, Corpora lutea/dam and There were no biologically meaningful or statistically significant differences in the number of litters and Foetal sex of treated rats were observed as compared to control. In addition, No effect on viability of foetuse, number of fetuses with malformations, number of foetuses or litters with developmental variations was observed in any of the treated groups. Slight increase in the number of litters with unossified sternebrae (sternebrae nos 1-6) and rudimentary 14thrib(s) was observed in feotus of 1500 mg/kg bw/day treated rats as compared to control, but the observed effect fell within the ranges of historical control data. Therefore, NOAEL was considered to be 1500 mg/kg body weight /day for F0 and F1 generation when CD Sprague-Dawley female rats were treated with test material orally.

 

Based on the data available from different studies,test chemical did not showed developmental toxicity at dose concentration1000 mg/kg bw/day.Hence the test chemical is not likely to classify as a reproductive and developmental toxicant as per the criteria mentioned in CLP regulation.

Therefore, NOAEL was considered to be 1500 mg/kg body weight /day for F0 and F1 generation when CD Sprague-Dawley female rats were treated with test material orally.

 

Based on the data available from different studies, test chemical did not showed developmental toxicity at dose concentration 1000 mg/kg bw/day.

Hence the test chemical is not likely to classify as a reproductive and developmental toxicant as per the criteria mentioned in CLP regulation.

Justification for classification or non-classification

Thus, comparing this value with the criteria of CLP regulation test chemical is not likely to classify as reproductive and developmental toxicant.
