SYNOPSIS In a 90-day feeding study, male and female albino rats were fed diets containing ^ H ^ t levels of 100, 500 or 2500 ppm. After 35 days of continuous'feeding, the 500 and 2500 ppm. dietary levels were increased to 1000 and 5000 ppm., respectively for the remainder of the study. After the prescribed 90-day period of com pound administration, representative animals were placed on a with drawal study. All rats appeared essentially normal with respect to behavior and appearance throughout the study. No adverse effect on body weight gain was found at any dietary level employed in this study, both in the active compound administra tion phase and in the withdrawal period. Average total weekly food consumption measured in grams/rat/week in those groups fed 100 and 500 - 1000 ppm. the diet compared favorably with the control rats throughout the study. At the 2500 - 5000 ppm. dietary level, food consumption of the male raps ranged from 1.1 to 8.7 per cent less than control male rats, and food consumption of the female rats ranged from 5.2 to 16.4 per cent less than the female control rats. These differences were first noted in the 8th week for males and in the 4th week for females and continued throughout the treatment period. No meaningful differences in food consumption were reflected by the treated groups of rats in comparison to the control group on the basis pf grams of food consumed per day per kilogram of body weight.

Urinalyses were normal at all times. Compound-related changes observed at the 90-day necropsy examina tion consisted of increased liver and kidney weight at the 1000 and 5000 ppm. dosage levels and pale yellowish livers in some male rats from the 500 - 1000 and 2500 - 5000 ppm. dosage levels. In histologic section, only livers from the 2500 - 5000 ppm. dosage level showed any change and this consisted of a slight hypertrophy of centrolobular hepatocytes. The increase in l^ver and kidney weights and centro lobular hepatocyte hypertrophy persisted with diminished magnitude through 21 days of compound withdrawal.

General Procedure: Eighty male (weighing from 45 to 64 grams) and eighty female (weighing from 47 to 63 grams) albino rats of the Charles River strain were used for this study. The rats were housed individually in cages suspended above the droppings in an air-conditioned room throughout the study and were fed a diet of Purina Laboratory Chow for rats ad libitum. Water also was available at all times. The animals were divided into one control group and three treated groups of 20 male and 20 female rats each. The rats in each sex group were selected so that the average body weight of each group was similar to that of the other groups of the same sex. 2. Compound Administration: incorporated into the standard powdered laboratory diet of Purina Laboratory Chow and offered to the treated groups of rats ad libitum. The test diet was freshly prepared each week and the compound-in-diet levels mixed so that the rats received^[|^|^^at dietary levels of 100, 500, or 2500 ppm. In the sixth week of com pound administration those groups receiving 500 or 2500 ppm. were increased in concentration to dietary levels of 1000 or 5000 ppm., respectively. Those animals receiving 100 ppm. o f ^ m | ^ i n the diet continued to receive this level throughout the 13-week study period. The control groups of rats received the powdered diet of Purina Laboratory Chow, but without Company Sanitized, Does not contain TS CA CBf Inzernational Research and Development Corporation Page 5 Following 13 weeks of compound administration rats in all groups were sacrificed and subjected to necropsy examination with the exception'of certain selected animals from the control`group and from the treated groups at the 1000 and 5000 ppm. dietary levels which were continued on study in a compound withdrawal phase. The withdrawal phase of this study will: be reported in its entirety in a subsequent and separate report. 3. Observations: The control and test animals were observed daily for mortality, alteration in general appearance and behavior, and signs of pharmaco dynamic and/or toxic effects. Body weights, food consumption, and food efficiency values were recorded for each rat weekly throughout the study. 4. Laboratory Tests: a . Hematology: Hematologic examination consisted of erythrocyte counts, 1. 2T total and differential leucocyte counts, hematocrits , and hemoglobin concentrations. These studies were performed individually on 6 male and 6 female rats randomly selected in the control and each test group during the control period and again at 30, 60, and 90 days. b . Urinalysis: Urine samples were obtained from the same animals at the same time intervals used to obtain blood for hematology.

The animals chosen for hematology values were not used for these bio chemical determinations. B. RESULTS: 1. General Behavior and Appearance: No adverse changes in behavior or appearance were encountered that could be related to the administration Animals in the control and all treated groups appeared essen tially normal each day with the exception of an occasional rat in each group that exhibited slight nasal and/or ocular porphyrin discharge. Other incidental findings, unrelated to compound administration, included one treated female animal (Rat #14374) at the 5000 ppm. dietary level which exhibited a swollen nose in the 13th week of study, one treated male (Rat #14298) at this dietary level which exhibited a mass on the flank from the 16th week (withdrawal period) until terminal necropsy examination, and one treated male (Rat #14324) at this same dietary level which exhibited destruction of the right eye, from the 15th week to the terminal (in the withdrawal period) necropsy examina tion. 2. Body Weights (Tables 1-8 and Figures 1 and 2): a. Control: The control animals maintained body weight curves which were consistent with those curves exhibited by control animals of the same age and strain maintained in these laboratories from time-to-time. b. 100 and 500 ppm.*: Male and female rats at these dietary levels maintained body weights which paralleled closely those of their respective control groups. * 500 ppm. dietary level increased to 1000 ppm. in the 6th week of study. zmpany Sanitized.

Male animals in the 9th week exhibited a body weight gain 8.8 per"cent less than control males. This difference in body weight gain persisted for the duration of the study period. During the withdrawal phase of this study the greatest decrease in body weight gain occurred. Even then, however, this difference was only about.10 per cent less than that of the male control animals. Female treated animals in this group in the 7th week of study exhibited a weight gain which was 11.5 per cent less than that of the control female animals. This difference in body weight gain per sisted for the duration of the treatment period. The greatest differ ence in body weight gain of the female group was noted in the 12th week of study at which time a difference of only 11.7 per cent occurred. 3. Food Consumption (Tables 10 and 11): a. Grams/Rat/Week: Average total weekly food consumption for male and female rats in those groups receiving 100 ppm. and 500 ppm.* compared favorably with similar measurements obtained from the control group. Treated rats receiving 2500 ppm.** showed food consumption values less than those of control animals beginning in the 4th week for treated females and in the 8th week for treated males. This decrease in food consumption continued throughout the study period and ranged from 1.1 to 8.7 per cent for the males and 5.2 to 16.4 per cent for the females in this group.

Grams/Kg,/Day: - No biologically meaningful differences were observed on food consumption in the treated groups of rats when compared with the control group on a basis of grams/kg./day food consumed. 4. Survival (Table 9): Other than for those animals subjected to interim necropsy examination at 30 and 60 days, all control and treated animals survived the course of study with two exceptions. One control female (Rat S) #14160) succumbed in the terminal (13th) week of study and one treated male (Rat #14212) at the 100 ppm. level of succumbed in the 11th week of study. 5. Laboratory Tests: a. Hematology: No compound-related hematologic changes were found at the 100 and 500 ppm. dietary levels At the 2500 ppm. level, group values for both sexes, with respect to erythrocyte count, hema tocrit and hemoglobin concentration, generally were slightly lower than those for the control animals and rats at the 100 and 500 ppm. dietary levels of though some changes in these parameters were seen at the 60-day interval of examination, they were overall more pronounced after 90 days of compound administration. It is of interest that inspection of these values for individual rats in the high dietary level groups failed to reveal marked changes for any given animal, that is, whereby that animal's value would tend to markedly lower the group average, but rather that lower values, with a relatively small spread from individual to individual, were found for most of these rats. Company Sanitized. Does not contain TSCA CUt International Research and Development Corporation Page 10 Group average values are summarized for male rats in Table 12 and for female rats in Table 13. Individual values for all male and female rats appear in Tables 14 through 17. . b. Plasma Biochemistry: No compound-related changes were found at any period of examination with respect to serum alkaline phosphatase activity or serum glutamic pyruvic transaminase (SGPT) or serum glutamic oxalacetic transaminase (SGOT) activities. Values obtained in these studies appear in Tables 18 through 21. c. Urinalysis : Urinalysis examinations failed to reveal changes which were considered to be related to treatment with the test compound. Results of these measurements appear in Tables 22 through 25.

Gross Examination: After 30 and 60 days of compound administration, 3 male and 3 female rats from the control and each treated group were sacri ficed by exsanguination and subjected to necropsy examination. After 90 days of compound administration, 10 male and 10 female rats from the control, 1000, and 5000 ppm. dietary level groups and all surviving rats from the 100 ppm. group were sacrificed by exsanguina tion and subjected to necropsy examination. Three male and 3 female rats from the control, 1000 and 5000 ppm. groups were sacrificed and subjected to necropsy examination after a 21-day compound withdrawal . period. (Other rats that remained on withdrawal beyond 21 days will be reported on in a separate report.) At necropsy major organs were weighed and representative tissues from each rat were collected into 10 per cent neutral buffered formalin for subsequent histologic processing. At the 90-day sacrifice, specimens of brain, liver, kidneys, muscle, fat, spleen, testes and blood were pooled by sex and diet^jry group, frozen and forwarded to the sponsor. Specimens of liver from the interim and withdrawal sacrifice were also pooled by sex and dietary group, frozen and shipped to the sponsor. Rats which died on study were also subjected to necropsy examination unless this was precluded by advanced autolysis. 2 \ Microscopic Examination: The following tissues from each of 3 male and 3 female rats from the control and high dosage groups from the 30 and 60-day interim and 21-day withdrawal sacrifices and from each of 10 male and 10 -.Dossgo!containTSGi.S International Research and Development Corporation Page 12 female control and high dietary group rats from the 90-day terminal sacrifice were paraffin-embedded, sectioned, stained with hematoxylin and' eosin and examined microscopically: brain spinal cord peripheral nerve eye pituitary thyroid parathyroid adrenal lung heart spleen lymph node thymus bone marrow salivary gland stomach small intestine large intestine pancreas liver kidneys urinary bladder testes or ovaries prostate or uterus skeletal muscle skin bone Sections of liver from 10 male and 10 female rats from the 1000 ppm. level - 90-day sacrifice rats were also processed as above and examined. B. RESULTS: ` 1. Gross Pathology (Table 26) and Organ Weights (Tables 2.7 and 28): Compound related gross changes observed at necropsy were limited to male rats from the 1000 and 5000 ppm. dietary level groups and consisted of pale, yellowish livers in some but not all male rats from the 5000 ppm. dietary level group and in a few rats from the 1000 ppm. dietary level group. None of the rats dying on study died of compound related causes. Rat #14160 (Control) died of pneumonia. Autolysis precluded diagnostic necropsy of Rat #14212 (100 ppm.). Compound related variations in organ weights were limited to the livers and kidneys of treated rats. At the 90-day sacrifice there was a moderate increase in actual and relative liver weights of the 1000 and 5000 ppm. dietary level rats. This increase was also seen in the 5000 ppm. dietary level rats at the 60-day interim Company Sanitized. Does not contain TSC CBii International Research and Development Corporaiion Page 13 sacrifice and in the 2500 ppm. dietary level rats at the 30-day interim sacrifice. After 21 days of compound withdrawal, a slrght increase in*liver weight persisted at the 5000 ppm. dietary level. - Mean actual and relative kidney weights were slightly^m the 1000 and 5000 ppm. dietary level rats at the 90-day sacrifice. Kidney weights were also slightly increased in the 1000 and 5000 ppm. level rats at the 60-day interim sacrifice and 21-day withdrawal sacrifice and in the 500 and 2500 ppm. level at the 30-day interim sacrifice. Although the values from the interim and withdrawal sacrifices represent only 3 rats per sex group, these variations in kidney weights always had a dietary-level relationship. 2. Histopathology (Tables 29 and 30): Compound related histopathologic changes were found only in the livers of rats from the highest (2500-5000 ppm.) dietary level and consisted of slight hypertrophy of centrolobular hepatocytes. Affected liver cells had cytoplasm which was less coarsely granular and more homogeneous than the unaffected cells at the periphery of the liver lobules and in the livers of rats in the control and lower dietary levels. This change, to a slight degree was seen after 30 days at the 2500 ppm. level. After this group was raised to 5000 ppm., the change was more marked at the 60 and 90-day sacrifices. A very slight change persisted in the 5000 ppm. level male rats sacrificed after a 21-day compound withdrawal period. This liver change was always more marked in male rats and was seen only at the highest (2500-5000 ppm.) dietary level. No lesions in other organs were considered to have been of compound related origin. No histologic basis was found for the slight increase in kidney weights in treated rats. oany Sanitized.
