Animal Husbandry
Environment
The Study Plan target values for temperature and relative humidity (RH) were 22 ± 3ºC and 50 ± 20% respectively. While there were no deviations from the target range for temperature, the target range for relative humidity was exceeded for extended periods of time during the study due to adverse weather conditions with the maximum humidity achieved being 79.31% RH.
The results of the study indicate that the animals remained in good health and, while it is accepted that these deviations from the target range for relative humidity were less than ideal, overall it is considered that these deviations had no adverse impact on the scientific purpose of the study. - GLP compliance:

- Animals and Animal Husbandry:
A sufficient number of male and female Wistar Han™:RccHan™:WIST strain rats were obtained from Harlan Laboratories U.K. Ltd., Blackthorn, Bicester, Oxon, UK. On receipt the animals were examined for signs of ill-health or injury. The animals were acclimatized for eight days during which time their health status was assessed. A total of ninety six animals (forty eight males and forty eight females) were accepted into the study. At the start of treatment the males weighed 278 to 335g, the females weighed 210 to 234g, and were approximately twelve weeks old.
Initially, all animals were housed in groups of four in solid floor polypropylene cages with stainless steel mesh lids and softwood flake bedding (Datesand Ltd., Cheshire, UK). During the pairing phase, the animals were transferred to polypropylene grid floor cages suspended over trays lined with absorbent paper on a one male: one female basis. Following evidence of successful mating, the males were returned to their original cages. Mated females were housed individually during gestation and lactation in solid floor polypropylene cages with stainless steel mesh lids and softwood flakes.
The animals were allowed free access to food and water. A pelleted diet (Rodent 2018C Teklad Global Certified Diet, Harlan Laboratories UK. Ltd., Oxon, UK.) was used. Mains drinking water was supplied from polycarbonate bottles attached to the cage. Environmental enrichment was provided in the form of wooden chew blocks and cardboard fun tunnels (Dates and Ltd., Cheshire, UK) except for paired animals and mated females during the final week of gestation and lactation. Mated females were also given softwood flakes, as bedding, throughout gestation and lactation. The diet, drinking water, bedding and environmental enrichment were considered not to contain any contaminant at a level that might have affected the purpose or integrity of the study.
The animals were housed in a single air-conditioned room within the Harlan Laboratories Ltd., Shardlow, UK Barrier Maintained Rodent Facility. The rate of air exchange was at least fifteen air changes per hour and the low intensity fluorescent lighting was controlled to give twelve hours continuous light and twelve hours darkness. Environmental conditions were continuously monitored by a computerized system, and print-outs of hourly temperatures and humidities are included in the study records. The Study Plan target ranges for temperature and relative humidity were 22 ± 3 °C and 50 ± 20% respectively. Deviations from these targets were considered not to have affected the purpose or integrity of the study; see deviations from Study Plan.
The animals were randomly allocated to treatment groups using a stratified body weight randomization procedure and the group mean body weights were then determined to ensure similarity between the treatment groups. The cage distribution within the holding rack was also randomized. The animals were uniquely identified within the study by an ear punching system routinely used in these laboratories.
Justification:
The rat was selected for this study as it is a readily available rodent species historically used in safety evaluation studies and is acceptable to appropriate regulatory authorities.

Discussion: The detection system was found to have acceptable linearity. The analytical procedure had acceptable recoveries of the test item in the vehicle. The method of analysis was validated and proven to be suitable for use. - Details on mating procedure:
- Animals were paired on a 1 male: 1 female basis within each dose group, for a period of up to fourteen days. Cage tray-liners were checked each morning for the presence of ejected copulation plugs and each female was examined for the presence of a copulation plug in the vagina. A vaginal smear was prepared for each female and the stage of estrus or the presence of sperm was recorded. The presence of sperm within the vaginal smear and/or vaginal plug in situ was taken as positive evidence of mating (Day 0 of gestation) and the males were subsequently returned to their original holding cages. Mated females were housed individually during the period of gestation and lactation.
- Duration of treatment / exposure:
- Chronological Sequence of Study:
i. Groups of twelve male and twelve female animals were treated daily at the appropriate dose level throughout the study (except for females during parturition where applicable). The first day of dosing was designated as Day 1 of the study.
ii. On Day 15, animals were paired on a 1 male: 1 female basis within each dose group for a maximum of fourteen days.
iii. Following evidence of mating (designated as Day 0 post coitum) the males were returned to their original cages and females were transferred to individual cages.
iv. Pregnant females were allowed to give birth and maintain their offspring until Day 5 post partum. Litter size, offspring weight and sex, surface righting and clinical signs were also recorded during this period.
v. The male dose groups were killed and examined macroscopically on Day 43.
vi. At Day 5 post partum, all females and surviving offspring were killed and examined macroscopically. - Frequency of treatment:
- The test item was administered daily by gavage using a stainless steel cannula attached to a disposable plastic syringe.
- Duration of test:
- The test item was administered by gavage to three groups, each of twelve male and twelve female Wistar Han™:RccHan™:WIST strain rats; males were treated for 42 consecutive days and females were treated up to and including Day 4 post partum (including a two week pre-pairing phase, pairing, gestation and early lactation for females), at dose levels of 100, 300 and 1000 mg/kg bw/day.

Examinations
- Maternal examinations:
- DETAILED CLINICAL OBSERVATIONS:
Yes
- Time schedule:
All animals were examined for overt signs of toxicity, ill-health and behavioral change immediately before dosing, soon after dosing, and one hour after dosing (except for females during parturition where applicable). All observations were recorded.
BODY WEIGHT:
Yes
- Time schedule for examinations:
Individual body weights were recorded on Day 1 (prior to dosing) and then weekly for males until termination and weekly for females until pairing. During the pairing phase females were weighed daily until mating was confirmed. Body weights were then recorded for females on Days 0, 7, 14 and 20 post coitum, and on Days 1 and 4 post partum.
FOOD CONSUMPTION:
Yes
- During the maturation period, weekly food consumption was recorded for each cage of adults. This was continued for males after the mating phase. During the pre-pairing period, weekly food consumption was recorded for each cage of adults until pairing. This was continued for males after the mating phase. For females showing evidence of mating, food consumption was recorded for the periods covering post coitum Days 0-7, 7-14 and 14-20. For females with live litters, food consumption was recorded during the lactation period (Days 1-4).
FOOD EFFICIENCY:
Yes
- Weekly food efficiency (body weight gain/food intake) was calculated retrospectively for males and for females during the pre-pairing phase. Due to offspring growth and milk production for lactation, food efficiency for females could not be accurately calculated during gestation and lactation.
WATER CONSUMPTION: Yes
- Time schedule for examinations: Water intake was observed daily by visual inspection of water bottles for any overt changes.
POST-MORTEM EXAMINATIONS: Yes
- Sacrifice
Adult males were killed by intravenous overdose of a suitable barbiturate agent followed by exsanguination on Day 43. Adult females were killed by intravenous overdose of sodium pentobarbitone followed by exsanguination on Day 5 post partum. Surviving offspring were terminated via intracardiac overdose of a suitable barbiturate agent. Any females which failed to achieve pregnancy or produce a litter were killed on or after Day 25 post coitum.
- Organs examined:
For all females, the uterus was examined for signs of implantation and the number of uterine implantations in each horn was recorded. This procedure was enhanced; as necessary, by staining the uteri with a 0.5% ammonium polysulphide solution (Salewski 1964). The corpora lutea were also counted. The epididymides and testes were removed from terminal kill adult males dissected free from fat and weighed before fixation.
Histopathology/organ weights:
All adult animals and offspring, including those dying during the study, were subjected to a full external and internal examination, and any macroscopic abnormalities were recorded.
Samples of the following tissues were preserved from all animals from each dose group, in buffered 10% formalin, except where stated:
Coagulating gland Prostate
Epididymides Seminal vesicles
Ovaries Testes
Mammary gland Uterus/Cervix
Pituitary Vagina
PREGNANCY AND PARTURITION
Each pregnant female was observed at approximately 0830, 1230 and 1630 hours and around the period of expected parturition. Observations were carried out at approximately 0830 and 1230 hours at weekends and public holidays. The following was recorded for each female:
i. Date of pairing
ii. Date of mating
iii. Date and time of observed start of parturition
iv. Date and time of observed completion of parturition - Ovaries and uterine content:
- The ovaries and uterine content was examined after termination:
For all females, the uterus was examined for signs of implantation and the number of uterine implantations in each horn was recorded.
Examinations included:
- Gravid uterus weight:
No
- Number of corpora lutea:
Yes
- Number of implantations:
Yes
- Number of early resorptions:
No
- Number of late resorptions:
No - Fetal examinations:
- LITTER DATA:
On completion of parturition (Day 0 post partum), the number of live and dead offspring was recorded. Offspring were individually identified within each litter by tattoo on Day 1 post partum.
For each litter the following was recorded:
i. Number of offspring born
ii. Number of offspring alive recorded daily and reported on Days 1 and 4 post partum
iii. Sex of offspring on Days 1 and 4 post partum
iv. Clinical condition of offspring from birth to Day 5 post partum
v. Individual offspring weights on Days 1 and 4 post partum (litter weights were calculated retrospectively from this data)
POST-MORTEM EXAMINATION
Surviving offspring were terminated via intracardiac overdose of a suitable barbiturate agent. All adult animals and offspring, including those dying during the study, were subjected to a full external and internal examination, and any macroscopic abnormalities were recorded. - Statistics:
- Statistical Analysis
Where considered appropriate, quantitative data was subjected to statistical analysis to detect the significance of intergroup differences from control; statistical significance was achieved at a level of p<0.05. Statistical analysis was performed on the following parameters:
Body Weight, Body Weight Change, Food Consumption during gestation and lactation, Pre-Coital Interval, Gestation Length, Litter Size, Litter Weight, Sex Ratio, Corpora Lutea, Implantation Sites, Implantation Losses, Viability Indices, Offspring Body Weight, Offspring Body Weight Change, Offspring Surface Righting, Absolute Organ Weights, Body Weight-Relative Organ Weights.
Data were analyzed using the decision tree from the ProvantisTM Tables and Statistics Module .
Data not analyzed by the Provantis data capture system were assessed separately using the the R Environment for Statistical Computing. Initially, the distribution of the data was assessed by the Shapiro-Wilk normality test, followed by assessment of the homogeneity of the data using Bartlett’s test. Where considered appropriate, parametric analysis of the data was applied incorporating analysis of variance (ANOVA), which if significant, was followed by pair-wise comparisons using Dunnett’s test. Where parametric analysis of the data was considered to be unsuitable, non-parametric analysis of the data was performed incorporating the Kruskal-Wallis test which if significant was followed by the Mann-Whitney "U" test.
Due to the preponderance of non-normally distributed data, reproductive parameters (implantation losses, offspring sex ratio and offspring surface righting) were analyzed using non-parametric analyses.
Probability values (p) are presented as follows:
p<0.01 **
p<0.05 *

Applicant's summary and conclusion
- Conclusions:
- The oral administration of FAT 40863/A TE to male rats by gavage for a period of 42 consecutive days and to female rats by gavage up to and including Day 4 post partum (including a two week pre-pairing phase, pairing, gestation and early lactation) at dose levels of 100, 300 and 1000 mg/kg bw/day did not result in any toxicologically significant effects of treatment.
The ‘No Observed Effect Level’ (NOEL) for reproductive/developmental toxicity was considered to be 1000 mg/kg bw/day. - Executive summary:
Introduction:
The study was performed to screen for potential adverse effects of the test item on reproduction, including offspring development, and provides an initial hazard assessment for effect on reproduction. The study is compatible with the requirements of the recommendations of the OECD Guidelines for Testing of Chemicals No. 421 “Reproduction/Developmental Toxicity Screening Test” (adopted 27 July 1995).
This study was also designed to be compatible with Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH).
Methods:
The test item was administered by gavage to three groups, each of twelve male and twelve female Wistar Han™:RccHan™:WIST strain rats; males were treated for 42 consecutive days and females were treated up to and including Day 4post partum(including a two week pre-pairing phase, pairing, gestation and early lactation for females), at dose levels of 100, 300 and 1000 mg/kg bw/day. A control group of twelve males and twelve females was dosed with vehicle alone (Distilled water).
Clinical signs, body weight change, dietary intake and water consumption were monitored during the study.
Pairing of animals within each dose group was undertaken on a one male: one female basis within each treatment group on Day 15 of the study, with females subsequently being allowed to litter and rear their offspring to Day 5 of lactation.
During the lactation phase, daily clinical observations were performed on all surviving offspring, together with litter size and offspring weights and assessment of surface righting reflex.
Adult males were terminated on Day 43, followed by the termination of all females and offspring on Day 5post partum. Any female which did not produce a pregnancy was terminated on or after Day 25post coitum. All animals were subjected to a gross necropsy examination and histopathological evaluation of reproductive tissues was performed.
