PROTOCOL NUMBER: 418-011 SPONSOR'S STUDY NUMBER: T-6316.7 I. SUMMARY AND CONCLUSION A. Methods8 Twenty-five Crl:CDBR VAF/Plus (Sprague-Dawley) presumed pregnant female rats were assigned to each of five dosage groups (Groups I through V). Nineteen additional female rats were assigned to one of five dosage groups for the satellite study (three, five, three, three and five rats assigned to Groups I through V, respectively). The test article, N-EtFOSE, or vehicle, 2% Tween 80 in Reverse Osmosis Membrane Processed Deionized Water (R.O. Deionized Water), was administered via gavage once daily to female rats on days 6 through 17 of presumed gestation (DGs 6 through 17). Dosages of 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day were administered at a dosage volume of 5 ml_/kg, adjusted daily on the basis of individual body weights. The female rats were observed for viability at least twice each day of the study. The rats were also examined for clinical observations of effects of the test article, abortions, premature deliveries and deaths before and approximately one hour after dosage (DGs 6 through 17), and once daily during the postdosage period. a. Detailed descriptions of all procedures used in the conduct of this study are provided in the appropriate sections of this report and in APPENDIX C (PROTOCOL AND AMENDMENT). 003594 418-011 P A G E I-2 Body weights were'recorded on DGs 0 and 4 and daily during the dosage and postdosage periods. Feed consumption values were recorded on DGs 0, 4, 6, 8, 10, 12, 14, 16, 18 and 20. All rats in the main study were sacrificed by carbon dioxide asphyxiation on DG 20 and a gross necropsy of the thoracic, abdominal and pelvic viscera was performed. The number of corpora lutea in each ovary was recorded. The uterus of each rat was examined for pregnancy, number and distribution of implantations, live and dead fetuses and early and late resorptions. Each fetus was identified, weighed and examined for sex and gross external alterations. Approximately one-half of the fetuses in each litter were examined for soft tissue alterations and the remaining fetuses in each litter were examined for skeletal alterations. Rats in the satellite study were sacrificed on DG 18. Blood samples were collected and centrifuged. The liver was excised, weighed and sectioned. Fetuses were examined grossly to the extent possible as described for rats assigned to the main study. Fetuses and placentae were pooled per litter. After completion of sample collection, serum, liver section, fetal and placental samples were shipped to the Sponsor for analysis. B. Results No deaths, abortions or premature deliveries occurred during the study. All rats survived until scheduled sacrifice on gestation day 20 (DG 20). All clinical and necropsy observations were considered unrelated to the test article. Maternal body weight gains were significantly reduced in groups administered 5 mg/kg/day and higher dosages of the test article. The effect was minimal and transient in the 5 mg/kg/day dosage group, occurring only on DGs 8 to 10. In the 10 mg/kg/day dosage group, significant reductions in maternal body weight gains occurred on DGs 6 to 8 and 10 to 12, followed by a significant increase in weight gain on DGs 14 to 16. The 20 mg/kg/day dosage group had significant weight loss followed by significant reductions in maternal body weight gain on DGs 8 to 14 and 16 to 18. These effects of the test article resulted in a tendency for reduced weight gain in the 10 mg/J<g/day dosage group and significant reductions in the 20 mg/kg/day dosage group for the entire treatment period (DGs 6 to 10), the entire interval after initiation of treatment (DGs 6 to 20) and the entire gestation period (DGs 0 to 20). Maternal body weights were 003S95 418-011 P A G E I-3 significantly reduce'd in the 10 and 20 mg/kg/day dosage groups on DGs 11 through 13 and 8 through 20, respectively. Body weights and body weight gains were unaffected by the 1 mg/kg/day dosage of the test article. The absolute feed consumption value was significantly reduced in the 10 mg/kg/day dosage group on DGs 6 to 8 and absolute and relative feed consumption values were significantly reduced in the 20 mg/kg/day dosage group for the entire dosage period and at all intervals within this period. The absolute feed consumption value continued to be significantly reduced and the relative feed consumption value tended to be reduced in the 20 mg/kg/day dosage group during the postdosage interval. These effects of the 20 mg/kg/day dosage of the test article resulted in significantly reduced absolute and relative feed consumption values on DGs 6 to 20 and DGs 0 to 20. Absolute and relative feed consumption values were unaffected by dosages of the test article as high as 5 mg/kg/day. Fetal body weights (total, male and/or female) were significantly reduced in the 10 and 20 mg/kg/day dosage groups, as compared to the control group values. Dosages of N-EtFOSE as high as 20 mg/kg/day did not affect any other Caesarean-sectioning or litter parameters. The litter averages for corpora ltea, implantations, litter sizes, live fetuses, early resorptions, percent resorbed conceptuses and percent male fetuses, as well as the numbers of dams with any resorptions or with viable fetuses were comparable in the five dosage groups and did not significantly differ. No dams had litters with all conceptuses resorbed, and there were no dead fetuses or late resorptions. All placentae appeared normal. All of these values were within the ranges observed historically at the Testing Facility. Reversible delays in fetal ossification associated with the significantly reduced fetal body weights in the 10 and 20 mg/kg/day dosage groups, were evident as significant reductions in the litter averages for ossified caudal vertebrae in the 10 and 20 mg/kg/day dosage groups and a significant increase in the fetal incidence of wavy ribs in the 20 mg/kg/day dosage group. All other fetal gross external, soft tissue and skeletal alterations (malformations and variations) were considered unrelated to the test article because: 1) the incidences were not dosage-dependent; and/or 2) the incidences were within ranges observed historically at the Testing Facility. 418-011 P A G E I-4 C. Conclusion On the basis of these data, the maternal no-observable-effect-level (NOEL) of N-EtFOSE is 5 mg/kg/day (the 10 and 20 mg/kg/day dosages caused biologically important and statistically significant reductions in body weight gains or weight losses, and the 20 mg/kg/day dosage also persistently reduced the absolute and relative feed consumption values). The developmental NOEL is also 5 mg/kg/day (the 10 and 20 mg/kg/day dosages significantly reduced fetal body weights and caused minimal, but statistically significant reversible delays in ossification of the caudal vertebrae; the 20 mg/kg/day dosage also significantly increased the incidence of wavy ribs, an additional reversible delay in ossification associated with the reduced fetal body weights).

Method of Randomization: Upon arrival, rats were assigned to individual housing on the basis of computer generated random units. Female rats were assigned to one of five dosage groups (Groups I through V), 25 rats per dosage group, using a computer generated (weight-ordered) randomization procedure based on body weights recorded on DG 0. Nineteen additional female rats were assigned to one of five dosage groups for the satellite study (three, five, three, three and five rats assigned to Groups I through V, respectively) using a computer-generated randomization based on body weights recorded on DG 0. E.9. System of Identification: Each rat was individually identified with a Monel self-piercing ear tag (Gey Band and Tag Co., Inc., No. M SPT 20101) inscribed with the rat's designated unique permanent number. Cage tags were marked with the study number and permanent rat number. . .* 003603 418-011 P A G E II-7 F. Husbandry: F.1. Research Facility Registration: USDA Registration No. 23-R-099 under the Animal Welfare Act, 7 U.S.C. 2131 et seq. F.2. Study Rooms: The study rooms were maintained under conditions of positive airflow relative to a hallway and independently supplied with a minimum of ten changes per hour of 100% fresh air that had been passed through 99.97% HEPA filters (Airo Clean room). Room temperature and humidity were monitored constantly throughout the study. Room temperature was targeted at 64F to 79F (18C to 26C); relative humidity was targeted at 30% to 70%. See APPENDIX E (TEMPERATURE AND RELATIVE HUMIDITY REPORT). F.3. Housing: Rats were individually housed except during the cohabitation period. During cohabitation, each pair of male and female rats was housed in the male rat's cage. All cage sizes and housing conditions were in compliance with the Guide for the Care and Use of Laboratory Animals<8). F.4. Lighting: An automatically-controlled fluorescent light cycle was maintained at 12-hours light: 12-hours dark, with each dark period beginning at 1900 hours EST. F.5. Sanitization: Cage pan liners were changed approximately three times each week. Cages were changed approximately every other week. F.6. Feed: Rats were given ad libitum access to Certified Rodent Diet #5002 (PMI Nutrition International, St. Louis, Missouri) in individual feeders. F.7. Feed Analysis: Analyses were routinely performed by the feed supplier. No contaminants at levels exceeding the maximum concentration for certified feed or deviations from 003604 418-011 P A G E II-8 expected nutritional requirements were detected by these analyses. Copies of the results of the feed analyses are available in the raw data. Neither the Study Director nor the Sponsor was aware of any agent present in the feed that was known to interfere with the results of this study. F.8. Water: Local water that had been processed by passage through a reverse osmosis membrane (R.O. water) was available to the rats ad libitum from individual water bottles attached to the cages and/or from an automatic watering system. Chlorine was added to the processed water as a bacteriostat. F. 9. Water Analysis: The processed water is analyzed twice annually for possible chemical contamination (Lancaster Laboratories, Lancaster, Pennsylvania) and monthly for possible bacterial contamination (Analytical Laboratories, Inc., Chalfont, Pennsylvania). Copies of the results of the water analyses are available in the raw data. Neither the Study Director nor the Sponsor was aware of any agent present in the water that was known to interfere with the results of this study. G. Methods: G.1.

Rationale for Dosage Selection: Dosages were selected on the basis of a dosage-range study (Argus Research Laboratories, Inc., Protocol 418-011P) that tested 0, 1, 5, 10, 25 and 35 mg/kg/day. In that study, body weight gain was decreased at 10 mg/kg/day and higher dosages, and feed consumption values were reduced at all dosages tested. G.3. Route of Administration: Oral (gavage) G.4. Rationale for Route of Administration: The oral (gavage) route was selected for use because: 1) in comparison with the dietary route, the exact dosage can be accurately administered; and 2) it is a proposed route of human exposure. G.5. Frequency of Administration: Appropriate dosages of the test article were administered orally (via gavage) once daily to female rats on DGs 6 through 17. Dosages of 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day of the test article were administered at a dosage volume of 5 mL/kg, adjusted daily on the basis of the individual body weights recorded before dosage. The rats were dosed at approximately the same time each day. G.6. Length of Study: Approximately 4 weeks G.7. Method of Study Performance: After acclimation, 190 healthy virgin female rats were placed into cohabitation with 190 breeder male rats (one male rat per female rat in the male rat's cage). Female rats with spermatozoa observed in a smear of the vaginal contents and/or a copulatory plug in situ were considered to be at DG 0 and returned to individual housing. The female rats were observed for viability at least twice each day of the study and for general appearance weekly during acclimation and on DG 0. The rats were also examined for clinical observations of effects of the test article, 0Q3606 418-011 P A G E 11-10 abortions, premature deliveries and deaths before and approximately one hour after dosage (DGs 6 through 17a), and once daily during the postdosage period. Body weights were recorded weekly during acclimation, on DGs 0 and 4 and daily during the dosage and postdosage periods (DGs 6 through 20). Feed consumption values were recorded on DGs 0, 4, 6, 8, 10, 12, 14, 16, 18 and 20. G.8. Gross Necropsvb: Rats Assigned to the Main Study: All rats were sacrificed by carbon dioxide asphyxiation on DG 20, Caesareansectioned and a gross necropsy of the thoracic, abdominal and pelvic viscera was performed. Uteri of apparently nonpregnant rats were stained with 10% ammonium sulfide to confirm the absence of implantation sites(9). Tissues with gross lesions were preserved in neutral buffered 10% formalin for possible future evaluation; all other maternal tissues were discarded. The number of corpora lutea in each ovary was recorded. The uterus of each rat was excised and examined for pregnancy, number and distribution of implantations, live and dead fetuses and early and late resorptions. An early resorption was defined as one in which organogenesis was not grossly evident. A late resorption was defined as one in which the occurrence of organogenesis was grossly evident. A live fetus was defined as a term fetus that responded to stimuli. Nonresponding term fetuses are considered to be dead (there were no dead fetuses). Dead fetuses and late resorptions are differentiated by the degree of autolysis present; marked to extreme autolysis indicated that the fetus was a late resorption. Each fetus was removed from the uterus, placed in an individual container and identified with a tag noting the study number, litter number, uterine distribution and fixative. Each fetus was subsequently weighed and examined for sex and gross external alterations. Live fetuses were sacrificed by an intraperitoneal a. See APPENDIX D (DEVIATIONS FROM THE PROTOCOL AND STANDARD OPERATING PROCEDURES OF THE TESTING FACILITY), item 1. b. A table of random units was used to select one control group rat from which all tissues examined at necropsy were retained, in order to provide control tissues for any possible histopathological evaluations of gross lesions. 003607 418-011 P A G E 11-11 injection of Beuthanasia-D Special (Schering-Plough Animal Health). Photographs of gross external fetal alterations are available in the raw data. Approximately one-half of the fetuses in each litter were examined for soft tissue alterations using an adaptation of Wilson's sectioning technique005. The fetuses were initially fixed in Bouin's solution; sections were stored in alcohol. The remaining fetuses in each litter were eviscerated, cleared, stained with alizarin red S(11), fixed in alcohol and examined for skeletal alterations. Skeletal preparations were retained in glycerin with thymol added as a preservative. Rats Assigned to the Satellite Study: On DG 18, rats assigned to the toxicokinetic evaluation were sacrificed and the following samples collected. Blood samples (approximately 4 ml_ per rat) were collected from the inferior vena cava into serum separator tubes and centrifuged. The resulting serum (approximately 2 mL) was immediately frozen on dry ice and maintained frozen (-70C) until shipment to the Sponsor for analysis. The liver was excised, weighed, and a sample section (lateral lobe) was frozen and retained at -70C until shipment to the Sponsor for analysis. Rats were Caesarean-sectioned and fetuses were examined grossly to the extent possible as described above for rats assigned to the main study. Fetuses and placentae were pooled per litter and retained frozen (-70C) until shipment to the Sponsor for analysis. After completion of sample collection, serum, liver section (lateral lobe), fetal and placental samples were shipped (frozen on dry ice) to the Sponsor for analysis. i Q93608 418-011 P A G E 11-12 G.9.

Test for homogeneity of variance. O93609 418-011:PAGE 11-13 Clinical observation and other proportion data were analyzed using the Variance Test for Homogeneity of the Binomial Distribution(12). Continuous data (e.g., maternal body weights, body weight changes, feed consumption values and litter averages for percent male fetuses, percent resorbed conceptuses, fetal body weights, fetal anomaly data and fetal ossification site data) were analyzed using Bartlett's Test of Homogeneity of Variances035 and the Analysis of Variance045, when appropriate [i.e., Bartlett's Test was not significant (p>0.05)]. If the Analysis of Variance was significant (p<0.05), Dunnett's Test055 was used to identify the statistical significance of the individual groups. If the Analysis of Variance was not appropriate [i.e., Bartlett's Test was significant (p<0.05)], the Kruskal-Wallis Test065 was used, when less than or equal to 75% ties were present. In cases where the Kruskal-Wallis Test was statistically significant (p<0.05), Dunn's Method of Multiple Comparisons075 was used to identify the statistical significance of the individual groups. If there were greater than 75% ties, Fisher's Exact Test085 was used to analyze the data. Count data obtained at Caesarean-sectioning of the dams were evaluated using the procedures described above for the Kruskal-Wallis Test065. Dam 12868 (5 mg/kg/day dosage group) had a litter consisting of five live fetuses and two early resorptions and dam 12889 (10 mg/kg/day dosage group) had a litter consisting of three live fetuses. Because such occurrences can abnormally skew the distribution of data095, statistical analyses were made with and without the values for these rats and litters. Maternal body weights, feed consumption values and Caesarean-section data for these dams and litters were excluded from summarization and statistical analyses; all values are presented on the individual tables. 003610 418-011 P A G E 111-1 III. RESULTS ' A. Mortality. Clinical and Necropsy Observations (Summaries - Tables 1 and 2: Individual Data - Tables 14 and 15) A.1. Mortality No deaths, abortions or premature deliveries occurred during the study. All rats survived until scheduled sacrifice on gestation day 20 (DG 20). A.2. Clinical Observations All clinical observations were considered unrelated to the test article because: 1) the incidences were not dosage-dependent; 2) the observations occurred in only one rat; and/or 3) the observations are common events in the laboratory environment. Clinical observations included localized alopecia on the underside, limbs and/or neck, ungroomed coat, cold to touch and fused second and third digits on the right forepaw. A. 3. Necropsy Observations The only necropsy finding was a tan area (0.6 cm x 0.8 cm) on the median lobe of the liver in one 20 mg/kg/day dosage group dam (12913). This observation was considered unrelated to the test article because it occurred in only one rat. B. Maternal Body Weights and Body Weight Changes (Figure 1: Summaries - Tables 3 and 4: Individual Data - Table 16) Maternal body weight gains were significantly reduced (p<0.05 or p<0.01) in groups administered 5 mg/kg/day and higher dosages of the test article. The effect was minimal and transient in the 5 mg/kg/day dosage group, occurring only on DGs 8 to 10. In the 10 mg/kg/day dosage group, significant reductions (p<0.05) in maternal body weight gains occurred on DGs 6 to 8 and 10 to 12, followed by a significant increase (p<0.05) in weight gain on DGs 14 to 16. The 20 mg/kg/day dosage group had significant weight loss (p<0.01) on DGs 6 to 8 followed by significant reductions (p<0.05 or p<0.01) in maternal body weight gain on DGs 8 to 14 and 16 to 18. These effects of the test article resulted in a tendency for reduced weight gain irvthe 10 mg/kg/day dosage group and significant reductions (p<0.01) in the 20 mg/kg/day dosage group for the entire treatment period (calculated as DGs 6 to 18), the entire interval after initiation of treatment (DGs 6 to 20) and the entire gestation period (DGs 0 to 20). Maternal 003611 418-011 P A G E III-2 body weights were significantly reduced (p<0.05 orp<0.01) in the 10 and 20 mg/kg/day dosage groups on DGs 11 through 14 and 8 through 20, respectively. Body weights and body weight gains were unaffected by the 1 mg/kg/day dosage of the test article. C. Maternal Absolute fo/dav) and Relative (o/kg/davl Feed Consumption Values (Summaries - Tables 5 and 6: Individual Data - Table 17) The absolute (g/kg/day) feed consumption value was significantly reduced (p<0.05) in the 10 mg/kg/day dosage group on DGs 6 to 8 and absolute (g/day) and relative (g/kg/day) feed consumption values were significantly reduced (p<0.01) in the 20 mg/kg/day dosage group for the entire dosage period (calculated as DGs 6 to 18) and at all intervals within this period. The absolute feed consumption value continued to be significantly reduced (p<;0.01) and the relative feed consumption value tended to be reduced in the 20 mg/kg/day dosage group during the postdosage interval (DGs 18 to 20). These effects of the 20 mg/kg/day dosage of the test article resulted in significantly reduced (p^0.01) absolute and relative feed consumption values on DGs 6 to 20 (the entire interval after the first dosage was administered) and DGs 0 to 20 (the entire gestation period). Absolute and relative feed consumption values were unaffected by dosages of the test article as high as 5 mg/kg/day. The significant reduction (p<0.05) in the relative feed consumption value in the 1 mg/kg/day dosage group on DGs 6 to 8 was considered unrelated to the test article because the value was not dosagedependent. D. Caesarean-Sectioning and Litter Observations (Summaries -Tables 7 and 8: Individual Data - Tables 18 through 20) Pregnancy occurred in 24 (96%), 23 (92%), 24 (96%), 25 (100%) and 24 (96%) of the rats in the 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day dosage groups, respectively. One 5 mg/kg/day dosage group litter consisted of five live fetuses and two early resorptions, and one 10 mg/kg/day dosage group litter consisted of three live fetuses. Because such occurrences can abnormally skew the distribution of the data(19>, values.for these dams and litters were excluded from data summarization and statistical analyses. As a result, Caesarean-sectioning observations were based on 24, 23, 23, 24 and 24 pregnant dams. 003612 418-011 P A G E III-3 Fetal body weights (total, male and/or female) were significantly reduced (p<.0.05 or p<;0.01) in the 10 and 20 mg/kg/day dosage groups, as compared to the control group values. The reduced fetal body weights in the 10 and 20mg/kg/day dosage groups were a reflection of body weight reduction of the dams at these higher dosage levels. Dosages of N-EtFOSE as high as 20 mg/kg/day did not affect any other Caesarean-sectioning or litter parameters. The litter averages for corpora ltea, implantations, litter sizes, live fetuses, early resorptions, percent resorbed conceptuses and percent male fetuses, as well as the numbers of dams with any resorptions or with viable fetuses were comparable in the five dosage groups and did not significantly differ. No dams had litters with all conceptuses resorbed, and there were no dead fetuses or late resorptions. All placentae appeared normal. All of these values were within the ranges observed historically at the Testing Facility3. E. Fetal Alterations (Summaries - Tables 9 through 13: Individual Data Table 211 Fetal alterations were defined as: 1) malformations (irreversible changes that occur at low incidences in this species and strain); and 2) variations (common findings in this species/strain, and reversible delays or accelerations in development). Litter averages were calculated for specific fetal ossification sites as part of the evaluation of the degree of fetal ossification. Fetal evaluations were based on 342, 349, 347, 354 and 326 DG 20 Caesareandelivered live fetuses in 24, 23, 24, 25 and 24 litters in the 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day dosage groups, respectively. Each fetus was examined for gross external alterations. Of these respective fetuses 166, 167, 169, 170 and 158 were examined for soft tissue alterations and 176, 182,178, 184 and 168 were examined for skeletal alterations and fetal ossification site averages. E.1. Summary of Fetal Alterations (Summary - Table 9: Individual Data Table 21) In the five respective dosage groups, litters with fetuses with alterations present numbered 6 (25.0%), 8 (34.8%), 4 (16.7%), 7 (28.0%) and 8 (33.3%). The numbers of fetuses with any alteration observed were 15 (4.4%), 10 (2.9%), 6 (1.7%), 8 (2.2%) and 12 (3.7%), and the percentages of fetuses with any alteration were 4.4%, 2.8%, 1.6%, 2.1% and 4.0%, in these same respective dosage groups. a. See APPENDIX G (HISTORICAL CONTROL,DATA). 003613 418-011 PAGE III-4 Reversible delays in fetal ossification*20,2"0 associated with the significantly reduced (p<0.05 or p<0.01) fetal body weights in the 10 and 20 mg/kg/day dosage groups, were evident as significant reductions (p<0.05) in the litter averages for ossified caudal vertebrae in the 10 and 20 mg/kg/day dosage groups and a significant increase (p<0.05) in the fetal incidence of wavy ribs in the 20 mg/kg/day dosage group. All other fetal gross external, soft tissue and skeletal alterations (malformations and variations) were considered unrelated to the test article because: 1) the incidences were not dosage-dependent; and/or 2) the incidences were within ranges observed historically at the Testing Facility. E.2. Fetal Gross External Alterations (Summary - Table 10: Individual Data - Table 21) E.2.a. Malformations One 10 mg/kg/day dosage group fetus (12885-15) had a short trunk and absent tail. Subsequent skeletal examination of this fetus revealed that only four cervical vertebrae were present and that there were no thoracic, lumbar, sacral or caudal vertebrae, or ribs. This fetus also had a variation in pelvic ossification (the pubes were not ossified). E.2.b. Variations No gross external variations occurred in the fetuses in this study. E.3. Fetal Soft Tissue Alterations (Summary - Table 11: Individual Data Table 211 E.3.a. Malformations No fetal malformations were identified at visceral examination. E.3.b. Variations E.3.b.1. Vessels Three control group fetuses (12801-10; 12810-10; 12821-6), one 1 mg/kg/day dosage group fetus (12834-14) and two 5 mg/kg/day dosage group littermates Q03614 418-011:PAGE III-5 (12860-5, -9) had the umbilical artery descending to the left of the bladder. These fetuses had no external findings and no other soft tissue alterations. Two 1 mg/kg/day dosage group fetuses (12826-12; 12837-9) had an absent innominate artery. No additional alterations occurred in these fetuses. E.3.b.2. Lunas One control group fetus (12822-4) had an absent apical lung lobe, and one 1 mg/kg/day dosage group fetus (12850-16) had an absent diaphragmatic lung lobe. No additional alterations occurred in these fetuses. E.3.b.3. Kidneys Two control group fetuses (12802-11; 12803-2) and one 10 mg/kg/day dosage group fetus (12877-14) had slight or moderate dilation of the pelvis of one or both kidneys, a reversible developmental delay(22). No additional alterations occurred in these fetuses. E.4. Fetal Skeletal Alterations (Summaries - Tables 12 and 13: Individual Data - Table 211 E.4.a. Malformations Externally malformed 10 mg/kg/day dosage group fetus 12885-15 had only four cervical vertebrae and no thoracic, lumbar, sacral or caudal vertebrae or ribs, as well as a variation in pelvic ossification (not ossified pubes), as previously described. E.4.b. Variations E.4.b.1. Skull A large nasal-frontal suture occurred in one 10 mg/kg/day dosage group fetus (12893-13). No additional alterations occurred in this fetus. E.4.b.2. Ribs A cervical rib at the 7th cervical vertebra, a common variation in this strain of r a t(23), occurred in 0, 3, 1, 3 and 4 fetuses from 0, 2 , 1 , 3 and 4 litters in the 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day dosage.groups, respectively. These fetuses had no other external or skeletal alterations. 003615 418-011 P A G E III-6 Wavy ribs, a reversible delay in ossification(21), occurred in one 1 mg/kg/day dosage group fetus (12848-1) and seven (p<;0.05) 20 mg/kg/day group fetuses (12904-1; 12909-5, -7, -10, -12; 12919-3, -9). One 20 mg/kg/day dosage group fetus (12909-7) also had incompletely ossified ribs. The significant increase in the fetal incidence of wavy ribs in the 20 mg/kg/day dosage group was considered a treatment-related developmental delay, associated with the significantly reduced (p<0.05 or p<0.01) fetal body weights in this dosage group. E.4.b.3. Sternum Delayed sternal ossification (incompletely ossified or not ossified 1st sternebra) occurred in 7, 2**, 1**, 1** and 1** fetuses from 3, 2, 1, 1 and 1 litters in the 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day dosage groups, respectively. Of these fetuses, one control group fetus (12802-1) had incompletely ossified pubes in addition to an unossified 1st sternal centrum. E.4.b.4. Pelvis The ischia and/or pubes were incompletely or not ossified in 3, 0, 2, 2 and 0 fetuses from 1, 0, 1 , 2 and 0 litters in the 0 (Vehicle), 1, 5, 10 and 20 mg/kg/day dosage groups, respectively. One fetus in the control group (12802-1) and one 10 mg/kg/day dosage group fetus (12885-15) had additional skeletal alterations, as previously described. E.4.b.5. Fetal Ossification Site Averages The litter averages for ossified caudal vertebrae per fetus were significantly reduced (p<0.05) in the 10 and 20 mg/kg/day dosage groups. These delays in caudal vertebral ossification were considered effects of the test article associated with the significantly reduced (p<0.05 or p<0.01) fetal body weights in these dosage groups. Analyses of the average numbers of fetal ossification sites per fetus did not reveal any other statistically significant differences among the five dosage groups. Ossification of the hyoid, vertebrae (cervical, thoracic, lumbar and sacral), ribs, sternum (manubrium, sternal centers and xiphoid), forelimbs (carpals, metacarpals and phalanges) and hindlimbs (tarsals, metatarsals and phalanges) occurred at similar incidences in litters in all dosage groups. All values were within the ranges observed historically at the Testing Facility. Significantly different from the vehicle control group (p< 0.01). 0Q3616 418-011 P A G E III-7 REFERENCES ' 1.

TEST SYSTEM: Species/Strain and Reason for Selection: The Crl:CDBR VAF/Plus (Sprague-Dawley) rat was selected as the Test System because: 1) it is one mammalian species accepted and widely used throughout industry for nonclinical studies of developmental toxicity (embryo-fetal toxicity/teratogenicity); 2) this strain has been demonstrated to be sensitive to developmental toxins; 3) historical data and experience exist at the Testing Facility0'3'; and 4) the test article is pharmacologically active in this species and strain. N um ber: Initial population acclimated: 190 virgin female rats. Population selected for study: 125 mated female rats (25 per dosage group). Population assigned to satellite study: Body W eight and Age: 19 mated female rats (five per Groups II and V and three per Groups I, III and IV) assigned to toxicokinetic evaluation. Female rats will be ordered to have body weights of 200 g to 225 g each at receipt, at which time they will be expected to be at least 60 days of age. Actual body weights will be recorded the day after receipt and will be documented in the raw data. The weight range will be included in the final report. 003716 418-011 PAG E C-6 Protocol 418-011 Page 6 Sex: Female rats will be given the test article. Male rats of the same source and strain will be used only as breeders and are not considered part of the Test System. Source: Charles River Laboratories, Inc. The rats will be shipped in filtered cartons by air freight and/or truck from Charles River Laboratories, Inc., to the Testing Facility. Identification: Rats are permanently identified using Monel self-piercing ear tags (Gey Band and Tag Co., Inc., No. MSPT 20101). Male rats are given unique permanent identification numbers upon assignment to the Testing Facility's breeder male rat population. Female rats are assigned temporary numbers at receipt and given unique permanent identification numbers when assigned to the study on the basis of day 0 of presumed gestation body weights. ANIMAL HUSBANDRY: All cage sizes and housing conditions are in compliance with the Guide for the Care and Use o f Laboratory A nim als^. Housing: The rats will be individually housed in stainless steel, wire-bottomed cages except during the cohabitation period. During cohabitation, each pair of rats will be housed in the male rat's cage. No nesting materials will be supplied because the female rats will be sacrificed before parturition is expected. Room Air. Tem perature and Hum idity: The animal room is independently supplied with at least ten changes per hour of 100% fresh air that has been passed through 99.97% HEPA filters (Airo Clean room). Room temperature will be maintained at 64F (18C) to 79F (26C) and monitored constantly. Room humidity will also be monitored constantly and maintained at 30% to 70%. Light An automatically controlled 12-hour light:12-hour dark fluorescent light cycle will be maintained. Each dark period will begin at 1900 hours EST. 003717 418-011: PAGE C-7 Protocol 418-011 Page 7 D ie t Rats will be given Certified Rodent Diet #5002 (PMI Nutrition International) available ad libitum from individual feeders. W ater: Water will be available ad libitum from individual bottles attached to the cages or from an automatic watering access system. All water will be from a local source and passed through a reverse osmosis membrane before use. Chlorine will be added to the processed water as a bacteriostat; processed water is expected to contain no more than 1.2 ppm chlorine at the time of analysis. Water is analyzed monthly for possible bacterial contamination and twice annually for possible chemical contamination. C ontam inants: Neither the Sponsor norths Study Director is aware of any potential contaminants likely to be present in the certified diet or in the drinking water at levels that would interfere with the results of this study. Therefore, no analyses other than those routinely performed by the feed supplier or those mentioned in this protocol will be conducted. RANDOMIZATION AND COHABITATION: Upon arrival, male and female rats will be assigned to individual housing on the basis of computer-generated random units. After acclimation, virgin female rats will be cohabited with breeder male rats, one male rat per female rat. The cohabitation period will consist of a maximum of five days. Female rats with spermatozoa observed in a smear of the vaginal contents and/or a copulatory plug observed in situ will be considered to be at day 0 of presumed gestation and assigned to individual housing. Healthy mated female rats will be assigned to dosage groups based on computergenerated (weight-ordered) randomization procedures. A D M IN IS TR A TIO N : Route and Reason fo r Choice: The oral (gavage) route was selected for use because: 1) in comparison with the dietary route, the exact dosage can be accurately administered; and 2) it is one of the proposed routes for clinical use. Method and Frequency: Female rats will be given the test article once daily on days 6 through 17 of presumed gestation, the period of organogenesis. Dosages will be adjusted for the most recently recorded body weight and given at approximately the same time each day. 003718 418-011 .PAGE C-8 Protocol 418-011 Page 8 Rationale for Dosage Selection: Dosages were selected on the basis of a dosage-range study (Argus Research Laboratories, Inc., Protocol 418-011P) that tested 0,1, 5,10,25 and 35 mg/kg/day. In that study, body weight gain was decreased at 10 mg/kg/day and higher dosages, and feed consumption values were reduced at all dosages tested. Dosage Levels.

Clinical Observations and/or General Appearance: Acclimation Period: Weekly. Predosage Period: Day 0 of presumed gestation. Dosage Period: Twice daily. Prior to dosage administration and once approximately one hour postdosage. Postdosage Period: Once daily. Clinical observations may be recorded more frequently than cited above, if deemed appropriate by the Study Director and/or Study Monitor. Body Weights: Acclimation Period: Weekly. Predosage Period: Day 0 and 4 of presumed gestation. 003719 418-011:PAGE C-9 Protocol 418-011 Page 9 Dosage Period: Daily. Postdosage Period: Daily. Feed Consumption Values (recorded and tabulated): Predosage Period: Day 0 and 4 of presumed gestation. Dosage Period: Days 6, 8,10,12,14 and 16 of presumed gestation. Postdosage Period: Days 18 and 20 of presumed gestation. Feed consumption values may be recorded more frequently if it is necessary to replenish the feed. These intervals will not be tabulated. Mating Performance: Mating will be evaluated daily during the cohabitation period and confirmed by observation of spermatozoa in a smear of the vaginal contents and/or a copulatory plug observed in situ. Caesarean-Sectioning Observations: Rats will be Caesarean-sectioned on day 20 of presumed gestation. The fetuses will be removed from the uterus and placed in individual containers. The rats will be examined for number and distribution of: Corpora Ltea. Implantation Sites. [Placentae appearance (size, color or shape if abnormal) will be noted in the raw data]. Live and Dead Fetuses. (A live fetus is defined as one that responds to stimuli; a dead fetus is defined as a term fetus that does not respond to stimuli and that is not markedly autolyzed; dead fetuses demonstrating marked to extreme autolysis are considered to be late resorptions.) Early and Late Resorptions. (A conceptus is defined as a late resorption if it is grossly evident that organogenesis has occurred; if this is not the case, the conceptus is defined as an early resorption.) 003720 418-011: PAGE C-10 Protocol 418-011 Page 10 Fetal Observations: Gross External Alterations and Sex: Fetuses will be examined for sex and for gross external alterations. Late resorptions and dead fetuses also will be examined for sex and for gross external alterations to the extent possible but such observations will not be included in either data summarization or statistical analyses. Body Weights and Identification: The body weight of each fetus will be recorded. Only body weights of live fetuses will be used to determine litter fetal body weight averages. Fetuses will be tagged with identification noting study number, litter number, uterine distribution and fixative. Soft Tissue Examination: Approximately one-half of the fetuses in each litter will be examined for soft tissue alterations by using an adaptation of Wilson's sectioning technique(S). The fetuses will be initially fixed in Bouin's solution; sections will be retained in alcohol. Skeletal Examination: The remaining fetuses (approximately one-half of the fetuses in each litter) will be examined for skeletal alterations after staining with alizarin red S(6>. The fetuses will be initially fixed in alcohol; skeletal preparations will be retained in glycerin with thymol added as a preservative. Representative photographs of fetal gross, soft tissue and skeletal alterations will be taken. METHOD OF SACRIFICE: Rats will be sacrificed by carbon dioxide asphyxiation. Live fetuses will be sacrificed by an intraperitoneal injection of euthanasia solution (Beuthanasia-D Special, manufactured by Schering-Plough Animal Health). NECROPSY: Gross lesions will be retained in neutral buffered 10% formalin for possible future evaluation (a table of random units will be used to select one control group rat from which all tissues examined at necropsy will be retained, in order to provide control tissues for any possible histopathological evaluations of gross lesions). Unless specifically cited below, ail other tissues will be discarded. 003721 418-011:PAGE C-11 Protocol 418-011 Page 11 Satellite Rats Assigned to Toxicokinetic Sample Collection: On day 18 of presumed gestation (the day following the last dosage), rats assigned to the toxicokinetic evaluation will be sacrificed and the following samples collected. Blood samples (approximately 4 mL per rat) will be collected from the inferior vena cava into serum separator tubes and centrifuged. The resulting serum (approximately 2 mL) will be immediately frozen on dry ice and maintained frozen (-70C) until shipment to the Sponsor for analysis. The liver will be excised, weighed, and a sample section (lateral lobe) will be frozen and retained at -70C until shipment to the Sponsor for analysis. Rats will be Caesarean-sectioned and fetuses will be examined grossly to the extent possible as described above for rats assigned to the main study. Fetuses and placentae will be pooled per litter and retained frozen (-70 C) until shipment to the Sponsor for analysis After completion of sample collection, serum, liver section (lateral lobe), fetal and placental samples will be shipped (frozen on dry ice) to Kris J. Hansen, Ph.D., at the previously cited address for analysis. Both the recipient and the Study Monitor will be notified in advance of sample shipment. Scheduled Sacrifice: On day 20 of presumed gestation, female rats will be Caesarean-sectioned, and a gross necropsy of the thoracic, abdominal and pelvic viscera will be performed. Uteri of apparently nonpregnant rats will be stained with 10% ammonium sulfide to confirm the absence of implantation sites575. Rate Found Dead or Moribund: Rats that die or are sacrificed because of moribund condition, abortion or premature delivery will be examined for the cause of death or moribund condition on the day the observation is made. The rats will be examined for gross lesions. Pregnancy status and uterine contents of female rats will be recorded. Aborted fetuses and/or delivered pups will be examined to the extent possible, using the same methods described for fetuses. Uteri of apparently nonpregnant rats will be stained with 10% ammonium sulfide to confirm the absence of implantation sites575. / 003722 418-011 .PAGE C-12 Protocol 418-011 Page 12 PROPOSED STATISTICAL METHODS**14: Averages and percentages will be calculated.

Once the final volumes are achieved, stir bars are to be added to the containers; mixing should occur during sampling and/or administration. C. Preparation of Vehicle 1. Add the required amount of R.O. deionized water to an appropriately labeled container. Heat the water to 50 5C, add the required amount of Tween 80 and mix until uniform (See TEST ARTICLE CALCULATIONS). D. Test Article Suspension Preparation: 1. To prepare the 4.0-mg/mL, Group V suspension, add the required amount of test article (See TEST ARTICLE CALCULATIONS) into an appropriately sized, labeled container. Add the required amount of vehicle and heat the mixture to 80 5C for approximately 30 minutes. 2. Once the test article has dissolved; spin over night while the solution cools. (Be sure there is a visible vortex, this will achieve the desired emulsion.) 3. To prepare the 2.0-mg/mL, Group IV suspension, remove the required amount of stock suspension (Group V) (See TEST ARTICLE CALCULATIONS), add the required amount of vehicle and mix. 4. To prepare the 1.0-mg/mL, Group III suspension, remove the required amount of stock suspension (Group IV) (See TEST ARTICLE CALCULATIONS), add the required amount of vehicle and mix. 003740 418-011: PAGE C-30 ATTACHMENT 3 Protocol 418-011 Version: 418-011 (28 JUL 98) Page 3 of3 TEST ARTICLE AND CONTROL ARTICLE PREPARATION PROCEDURE 5.
