Serum samples were analyzed at 2, 4, 6, 8,12, 24, and 48 hours post dose. There is a rapid decrease in serum level o f total organic fluorine with time. The biological half-life is on the order o f 4 hours. There is very little total organic fluorine present in liver or serum at 48 hours post intravenous dose o f L -13492 (T-6067). The pharmacokinetic study suggests that interpretation o f dermal absorption o f L -13492 (to be done and reported in a separate study) will be more difficult. It is unlikely that the serum levels at 48 hours and the liver samples at 28 days will contain any detectable organic fluorine whatever the extent o f dermal absorption. 2.0 IN TR O D U C TIO N ______________________________________________________ This study was designed to provide information as to whether L -13492 when administered as a single intravenous dose results in total organic fluoride increase in whole liver at 48 hours post dose or in serum at 2, 4, 8, 12, 24, or 48 hours. This information is to be acquired in order to interpret a subsequent dermal absorption study with the same compound (HWI#6329-152, AM DT-011095.1). The dermal absorption study will be reported separately. 3.0 TEST M ATERIALS____________________________________________________ 3.1 Test, Control, and Reference Substances and M atrices 3.1.1 A nalytical Reference Substance: FC-95, lot 161 or 171.

For biological samples the storage is -2010 C. 3.6 D isposition o f Test and Control Substances: Biological tissues and fluids will be retained per GLP Regulation for the time period required for studies longer than 28 days. This study is in parallel with a 28 day absorption study, so all tissues will be retained. 4.0 EXPER IM EN TA L-O verview Serum and tissues from animals dosed as described (HW I#6329-151) were available for analysis by combustion with subsequent analysis by selective ion electrode or by electrospray mass spectrometry. The tissue and serum samples were analyzed for total organic fluorine to collect information in order to support a dermal absorption study. The extent o f analysis will be at the discretion o f the Study Director. The samples arise from a previous study (HW I#6329-151) in which single rabbits were dosed intravenously with L -13492 at doses ranging 4 to 24 mg/kg. (See attached protocol for dosing, tissue collection, etc.) In the final report from HWI on this study the dosing is from 4 to 24 mg/kg. In the original protocol, the dosing is to 160 mg/kg. A rabbit dosed at 40 mg/kg died 5 minutes after injection. N o tissues were saved. 5.0 EXPERIM ENTAL - M ETHODS 5.1 A M D T-M -1-0, Thermal Extraction o f Fluoride by Means o f a Modified Dohrmann DX2000 Organic Halide Analyzer-Liver 5.2 A M D T-M -2-0, Fluoride Measurement by Means o f an Orion EA940 Expandable Ion Analyzer 5.3 A M DT-M -4-0, Extraction o f Fluorochemicals from Rabbit Liver 5.4 AM DT-M -5-0, Analysis o f Rabbit Liver Extract for Fluorochemicals Using Electrospray Mass Spectrometry 5.5 AM DT-M -8-0, Analysis o f Fluoride Using the Skalar Segmented Flow Analyzer with Ion Selective Electrode 5.6 A M D T-M -14-0, Thermal Extraction o f Fluoride by Means o f a Modified Dohrmann DX2000 Organic Halide Analyzer-Serum G253f 6.0 DATA ANALYSIS The data are attached for total organic fluorine analysis o f liver at 48 hours post dose. The total organic fluorine for whole liver for control animals, 4 mg/kg, 16 mg/kg, and 24 mg/kg intravenous doses o f a 45% solution are 20 ug, 43 ug, 66 ug, and 54 ug. Each data point represents one animal. An animal dosed with 40 mg/kg died 5 minutes after injection. The data are attached for serum concentrations o f total organic fluorine at 2, 4, 6, 8, 12, 24, and 48 hours post dose. What is immediately apparent is that the concentrations decrease rapidly with time and are non-detectable at 48 hours. The biological half-life appears to be about 4 hours (see pages 84-86). It appears likely that this salt o f perfluorooctanoate is rapidly eliminated from female rabbits. It is not known if there is a sex difference in the elimination o f the perfluorooctanoate in rabbits as is observed with rats. Other data was collected using electrospray mass spectrometry and Skalar segmented flow analyzer with ion selective electrode (see appendices). This data, although supportive, in the opinion o f the Study Director is not required to reach the conclusion stated here and therefore is not discussed in detail. 6.1 Circum stances that M ay Affect the Q uality o f the Data: The problem with this analysis is that there is not a good biological marker and thus the pharmacokinetic study does not provide a good avenue for the interpretation o f a dermal absorption study 7.0 CO NCLUSIO N______________________________________________________ There is very little total organic fluorine present in liver at 48 hours post intravenous dose o f L-13492. The pharmacokinetic study suggests that interpretation o f dermal absorption o f L-13492 (to be done and reported in a separate study) will be very difficult. 8.0 M AINTENANCE OF RAW DATA AND RECORDS__________________ 8.1 Raw Data and Data: Raw data, approved protocol, approved final report, appropriate specimens, and electronic data will be maintained in the AMDT archives. 00253^ 4 9.0 APPENDICES 9.1 Protocol and Am endm ents 9.1.1 Protocol and Final Report: HWI#6329-151 "Single-Dose Intravenous Pharmacokinetic Study o f T-6067 in Rabbits" (Protocol type TP8084.PK for dosing o f animals, tissue collection, etc.) 9.1.2 Analytical protocol AM DT-120694.1 9.2 Signed Reports from Individual Scientists: None 9.3 Q uality Assurance Unit Statement: See attached 9.4 K ey Personnel Involved in the Study: See attached 9.5 M aterials and Equipment: See methods 9.6 Solutions, Reagents, and Standards: See methods 9.7 Sample Preparation: See methods 9.8 Quality Control Practices: See methods 9.9 Test Methods: See Protocol AMDT-120694.1 9.10 Instrum ent Settings: See methods 9.11 Data: See attached. 9.11.1 Summary and raw data; ug F' in whole liver as determined by thermal extraction followed by analysis using Orion ion analyzer. 9.11.2 Summary and raw data; ppm F* in serum as determined by thermal extraction followed by analysis using Orion ion analyzer. 9.11.3 Summary and raw data; ppm F' in serum as determined by thermal extraction followed by analysis using Skalar segmented flow analyzer with ion selective electrode. 9.11.4 Summary and raw data; analysis o f liver extracts using electrospray mass spectrometry. 0025 9.1.1 Protocol and Final Report: HWI#6329-151 "Single-Dose Intravenous Pharmacokinetic Study o f T-6067 in Rabbits" (Protocol type TP8084.PK for dosing o f animals, tissue collection, etc.) 00253^ . HAZLETON WISCONSIN P I J M O f F I <' B O X 7 B 4 6 T / i A n r . o r j 'A'i -, , ; / o ' / 6 4 l> Sponsor: 3M St. Paul, Minnesota CO RN IN G ( ru h v FINAL REPORT Study Title: Single-Dose Intravenous Pharmacokinetic Study of T-6067 in Rabbits Author: Steven M.

Female Hra:(NZW)SPF rabbits were assigned at random to five groups (one/group). On Day 0, the animals received a single intravenous injection of the vehicle (sterile water for injection) or 4, 16, 24, or 40 mg of T-6067/kg of body weight at a dose volume of 0.5 mL/kg. Clinical observations were conducted at approximately 0.5, 2, 4, 24, and 48 hours after intravenous injection. Body weights were determined just before test material administration (Day 0). A blood sample (approximately 4 mL) was collected from an auricular artery or marginal ear vein of the surviving animals at 2-, 4-, 6-, 8 -, 12-, 24-hours post-injection. In addition, at the time of experimental termination (48-hours post-injection), approximately 20 mL of blood was obtained from each surviving animal. All samples were centrifuged, separated into serum and cellular fractions, and sent to the Sponsor. The one animal (40 mg/kg) found dead during the study was necropsied but tissues were not saved. Animals surviving to the end of the 48-hour post-injection period were anesthetized with sodium pentobarbital, bled via the posterior vena cava, and exsanguinated. An abbreviated gross necropsy examination was not done, however, tissues were collected. The whole liver, bile, and both kidneys from each animal surviving to termination were collected and sent frozen to the Sponsor after termination of the in-life phase. The animals treated at 0, 4, 16, and 24 mg/kg appeared normal throughout the study. The animal treated at the 40 mg/kg dose level died within 5 minutes of dosing. At necropsy, the lungs in this animal were diffusely dark red. This change was attributed to acute death and postmortem change. O02S4* if;* Page 7 of 28 HWI 6329-151 OBJECTIVE The objective of this study was to assess the level of systemic exposure to the test material, T-6067, when administered as a single intravenous injection to rabbits. REGULATORY COMPLIANCE This study was conducted in accordance with the U.S. Food and Drug Administration's Good Laboratory Practice Regulations for Nonclinical Laboratory Studies, 21 CFR 58, with the exception that analysis of the test mixtures for concentration, homogeneity/solubi1 ity, and stability was not conducted. All procedures used in this study were in compliance with the Animal Welfare Act Regulations. In the opinion of the Sponsor and study director, the study did not unnecessarily duplicate any previous work. TEST AND CONTROL MATERIALS Identification The test material was identified as T-6067 and described as a clear, colorless liquid. The control material was Sterile Water for Injection, USP (Abbott Laboratories, Lot No. 86-748-DM-02; Exp. March 1, 1996), and was described as a clear, colorless liquid. Purity and Stability The Sponsor assumes responsibility for test material purity and stability determinations (including under test conditions). A sample of the test material/vehicle mixtures for concentration, solubility, homogeneity, and stability analyses was not taken before administration as this was not requested by the Sponsor. The purity and stability of the USP grade control material were considered to be adequate for the purposes of this study. Storage and Retention The test material was stored at room temperature. The control material was stored refrigerated. Any unused test material was returned to the Sponsor after completion of all testing according to Hazleton Wisconsin (HWI) Standard Operating Procedure (SOP). Any remaining vehicle may be used for other testing and will not be discarded after issuance of the final report. 00254^ Page 8 of 28 HWI 6329-151 Safety Precautions The test and control material handling procedures were according to HWI SOPs and policies. TEST SYSTEM Test Animal Adult albino rabbits of the Hra:(NZW)SPF strain were received from HRP, Inc., Kalamazoo, Michigan on November 16, 1994 and maintained at the Hazleton Wisconsin facility at 3802 Packers Avenue, Madison, Wisconsin. Housing After receipt, the animals were acclimated for a period of at least 7 days. During acclimation and throughout the study, the animals were individually housed in screen-bottom stainless steel cages in temperature- and humiditycontrolled quarters. Environmental controls for the animal room were set to maintain a temperature of 19* to 230C , a relative humidity of 50% 20%, and a 12-hour 1ight/12-hour dark lighting cycle. In cases where variations from the required temperature and humidity conditions existed, they were documented and considered to have had no adverse effect on the study outcome. Animal husbandry and housing at HWI complied with standards outlined in the "Guide for the Care and Use of Laboratory Animals" . 1 Animal Diet The animals were provided access to water ad libitum and a measured amount of Laboratory Rabbit Diet HF #5326, PMI Feeds, Inc. The feed is routinely analyzed by the manufacturer for nutritional components and environmental contaminants. Samples of the water are periodically analyzed by HWI. There were no known contaminants in the feed or water at levels that would have interfered with or affected the results of the study. Selection of Test Animals The animals were identified by animal number and corresponding ear tag and were selected at random based on health and body weight requirements. 00254 Page 9 of 28 HWI 6329-151 Study Design Female animals weighing from 2,511 to 2,781 g at initiation of treatment were placed into the following study groups: Group 1 (Control) 2 3 4 5 Treatment * T-6067 T-6067 T-6067 T-6067 Dose Level ima T-6067/kq) 0 4 16 40 24 Dose Volume (mL/kal 0.5 0.5 0.5 0.5 0.5 Number of Anima 1 1 1 1 1 * Sterile Water for Injection, USP. Justification for Species Selection Historically, the New Zealand White albino rabbit has been the animal of choice because of the large amount of background information on this species. PROCEDURES Dose Preparation and Administration The test material was diluted with Sterile Water for Injection to achieve a specific concentration for each dose level. An individual dose of each respective test solution or control was calculated for each animal based on its body weight on the day of treatment. The respective test solution was administered by intravenous injection into a marginal ear vein. The dose was given as a slow push (approximately 30 to 60 seconds in duration). The prepared test solutions were stored at room temperature until administered. After administration, any remaining test solutions were discarded. Reason for Route of Administration Intravenous injection is an acceptable route to assess systemic exposure. Observations of Animals Clinical observations were conducted at approximately 0.5, 2, 4, 24 and 48 hours after intravenous injection. Body weights were determined just before test material administration (Day 0). C02S4 Page 10 of 28 HWI 6329-151 Sample Collection Blood samples (approximately 4 mL) were collected from either ear via the catheterization of the auricular artery or from the marginal ear vein of all surviving animals at 2, 4, 6 , 8 , 12, and 24 hours post-injection. At the time of necropsy (approximately 48-hours post-injection) approximately 20 mL of blood was obtained from the posterior vena cava of each surviving animal. All samples were stored at room temperature until centrifuged and separated into serum and cellular fractions. The blood samples were then stored in a freezer set to maintain a temperature of -20*C 10*C until shipped to the Sponsor. Pathology The animal found dead immediately after dosing (40 mg/kg) was subjected to an abbreviated gross necropsy examination and any abnormalities were recorded. No tissues were collected from this animal. At termination of the experimental phase, surviving animals were anesthetized with sodium pentobarbital and exsanguinated without necropsy however tissues were collected. The whole liver, bile, and both kidneys from each animal surviving to termination were collected and immediately placed on dry ice, then frozen by placing in a freezer set to maintain a temperature of -20*C 10C. After tissue/bile collection, the animals were discarded. Shipment of Tissues After completion of the in-life phase the blood samples, livers, bile, and kidneys were sent frozen (on dry ice) to the Sponsor (James D. Johnson, 3M E.E. & P.C., Bldg. 2-3E-09, 935 Bush Avenue, St. Paul, MN, 55106). The Sponsor is responsible for the retention and disposition of the samples. HWI does not accept any responsibility for the analysis of the samples collected in this study nor are these results presented in this report. Statistical Analyses No statistical analyses were required by the protocol. Location of Raw Data. Records, and Final Report The raw data, records, and an original signed copy of the final report will be retained in the archives of HWI in accordance with HWI SOP. 00254)1 Page 11 of 28 RESULTS Body Weights Individual body weights are in Table 1. HWI 6329-151 Clinical Observations Individual clinical signs are in Table 2. The animals treated at 0, 4, 16, and 24 mg/kg appeared normal throughout the study. The animal treated at 40 mg/kg died within 5 minutes of dosing. Pathology The animals treated at 0, 4, 16, and 24 mg/kg survived to termination of the experimental phase and were not examined grossly when sacrificed. The animal treated at 40 mg/kg died on the day of treatment and was necropsied. The lungs in this animal were diffusely dark red. This change was attributed to acute death and postmortem change. DISCUSSION The level of systemic exposure of T-6067 was evaluated in female albino rabbits when administered as a single intravenous injection at levels of 0, 4, 16, 24, and 40 mg/kg. The animals treated at 0 , 4, 16, and 24 mg/kg appeared normal throughout the study. Administration of this material at 40 mg/kg resulted in the death of the animal. SIGNATURE Steven M.

Use forceps or probe to transfer tissues. 7.2 Samples of liver are cut from frozen liver and placed in a tared and labeled weigh boat. Use a clean scalpel and cutting board. The cutting board and scalpel should be cleaned with water, methanol, or methanol-water solution after each liver is cut. 8.0 C A L IB R A T IO N AND STA N D A R D IZA TIO N __________________________ 8.1 Preparation of Calibration Standards 8.1.1 The standards required for each project will need to be appropriate for that individual project. Refer to protocol for that project. 8.1.2 Typically 50-500 ppm FC-95 in methanol standards are used. 8.1.3 For rabbit liver studies, use beef liver as the matrix. Cut a piece of frozen beef liver (100 150 mg) and weigh it in a labeled and tared weigh boat. 8.2 Calibration - Overview The normal calibration is the fluoride curve (AMDT-M-2). However, if an optional spiked liver curve is required the procedure listed below is used. 8.2.1 A calibration curve for the DX2000 is generated by spiking samples with known standards and combusting them using the same methods and matrix type as the samples to be tested. 8.2.2 Typically, three replicates of each standard and five concentrations of standards will be spiked. 8.2.3 Standard curve will be plotted as Mass Spiked F (ug) on the x-axis and Standard Mass Recovered F (ug) on the y-axis. Generate a regression curve and calculate the equation for the line and the r^ value. 8.2.4 Mass Spiked F (ug) = (Amount spiked in mL) x ( Cone, of standard in ppm) x (0.6004)* *FC-95 is 60.04% F therefore 0.6004 is the factor used to convert FC-95 to F 8.2.5 Standard Mass Recovered F (ug) = (TISAB volume in mL) x (Orion reading in ppm) 8.3 Calibration - Procedure 8.3.1 Start Up 8.3.1.1 Run 2 or more Clean Cycles when starting instrument each day. More clean cycles may be used if the previous samples contained high concentrations of fluoride. 8.3.2 Blanks 8.3.2.1 Prepare sample using the same methods and type of matrix as the test sample. 8.3.2.2 For rabbit studies, use beef liver as the matrix. Prepare at least 3 samples of beef liver (100- 150 mg) for blanks. 8.3.2.3 Put sample in Dohrmann boat. Combust each sample as described in section 9.0 and analyze sample according to method AMDT-M-2 for the ion selective electrode analysis. 3 8.3.2.4 For rabbit studies, the meter reading for a blank sample should be 0.03 ppm or lower before proceeding with the calibration. Bum samples until this limit is reached, or until in the judgement of the operator the reading is stable with respect to historical readings (previous 48 hours). 8.3.2.5 For non-rabbit studies, the blank readings should reach a predetermined ion concentration before proceeding with the calibration. 8.3.2.6 It may be necessary to mix approximately 50 mg of charcoal with the sample to aid combustion. 8.3.3 Standard Curve 8.3.3.1 Weigh out at least 15 matrix samples (5 standards with 3 replicates each) in tared and labeled weigh boats. For rabbit studies, weigh 100-150 mg beef liver samples. Record weights in study data. Store the matrix samples on dry ice or ice packs to keep them frozen until used. 8.3.3.2 Place weighed beef liver sample in Dohrmann sample boat. 8.3.3.3 Start with the lowest standard concentration. Using a Hamilton syringe, eject a fixed quantity of the standard on or in the matrix. For rabbit studies, use 4 uL of standard and eject it on or in the beef liver. 8.3.3.4 At least 3 replicates should be used for the lowest standard concentration; more replicates may be used at the discretion of the analyst. 8.3.3.5 Combust the sample as described in section 9.3 and analyze according to AMDT-M-2. 8.3.3.6 Run all 15 standards. If one replicate is significantly different from the other two replicates, run another sample for that standard. Indicate in data that the new replicate replaces the old replicate and that the new replicate will be used to calculate the regression curve. 8.3.3.7 When all standards have been run, calculate the r^. r^ must be at least 0.95. If it is not at least 0.95, consult with supervisor. 8.3.3.8 A new standard curve should be run when the combustion tube or sample matrix is changed. New standard curve may also be run at the discretion of the analyst. 8.4 Storage Conditions for Standards 8.4.1 Storage requirements for standards are dependent on the individual standards used. Typically, standards are stored at room temperature in plastic screw top bottles. 8.4.2 New FC-95 standards should be prepared at least once a month. 9.0 PROCEDURES 9.1 Typical Operating Conditions: 9.1.1 Combustion tube temperature = 950C. 9.1.2 Oxygen and Helium flow = 50 cc/minute. 9.1.3 Vaporization/Drying time = 240 seconds. 9.1.4 Bake time = 300 seconds. 9.2 Start Up Procedure: 9.2.1 If the program is not started, start the EOX program on the PC. 9.2.2 Open the SYSTEM SETUP window. 9.2.3 Put the furnace module and the cell in the READY mode. 9.2.4 Close the SYSTEM SETUP window. 4 9.2.5 When the oven has reached the READY temperature, run the CLEAN BOAT program found in the CELL CHECK menu. 9.2.6 See AMDT-EP-3 for details of the Dohrmann software. 9.3 Sample Extraction Procedure: 9.3.1 Open the SAMPLE HATCH and place the sample in the BOAT. It may be necessary to mix approximately 50 mg of charcoal with the sample to aid combustion. If this is done, charcoal should also be mixed in while establishing the baseline and when generating the standard curve. 9.3.2 Close SAMPLE HATCH. 9.3.3 Add appropriate volume ofTISAB solution or 1:1 TISAB:Milli-QTM water mixture to a labeled sample collection vial. Typically 0.6 mL to 15 mL are used. For rabbit studies, use 1.0 or 2.0 mL of 1:1 TISAB:Milli-QTM water mixture. 9.3.4 Place the vial so that the tip of the COMBUSTION TUBE is in the TISAB at least 0.25 inches. Gases released during pyrolysis must bubble through the TISAB. 9.3.5 Run the EOX-SOLIDS program found in the RUN menu. 9.3.6 When the EOX program is finished, remove the collection vial from the combustion tube. 9.3.7 If undiluted TISAB was used to collect the sample, add an equal volume of Milli-QTM water to the TISAB to make 1:1 TISAB:Milli-QTM. 9.3.8 Rinse the end of the combustion tube with Milli-QTM water and wipe with a KIMWEPE to remove any TISAB remaining on the tube. 9.3.9 Open the sample hatch and remove any remaining ash from the boat. Ash can be removed with a cotton tipped applicator or vacuumed out. It may be necessary to scrap particles off the bottom with a spatula or other similar device. A drop of Milli-QTM water may be added to the boat to aid in the Clean Cycle. 9.3.10 Close the hatch. 9.3.11 Run the CLEAN BOAT program. 9.3.12 Sample is ready for analysis by ion selective electrode (AMDT-M-2). 9.4 Sample Calculations 9.4.1 Use the standard curve to calculate the sample value. 9.4.2 Sample Mass Recovered F (ug) = (TISAB vol in mL) x (Orion reading in ppm - intercept! (Slope) 10.0 VALIDATIO N 10.1 Quality Control 10.1.1 Daily Start Up Check Samples: Once the standard curve is established, each day of analysis is started by analyzing QC samples. The QC samples are to be the same as the lowest concentration spiked samples used to generate the standard curve. Each concentration must be done in triplicate unless the first two replicates are within 20% of the standard curve, then a third replicate is not necessary. 10.2 Precision and Accuracy: See method development analysis and sample analysis in Fluoride Notebooks 2,3, and 5. Precision and accuracy varies when analyzing samples of different matrices and different reference compounds. 10.3 Other Validation Parameters: NA 5 11.0 DATA ANALYSIS 11.1 Calculations 11.1.1 For the standard curve, use regression analysis in Excel, version 5.0 or greater. 11.1.2 To calculate the fluoride contraction in the sample, see method AMDT-M-2. 11.2 Analyzing the Data 11.2.1 P- must be at least 0.95 or greater. "Outliers" may be excluded if two of the three replicates are within 20% of each other and the outlier is greater than 200% of the average of those two or less than 50% of the average of those two. Any such outliers should be pointed out in the data and noted in the Final Report along with the reason it was considered an outlier. 12.0 A T TA C H M EN TS_____________________________________________________ None 13.0 R E F E R E N C E S________________________________________________________ 13.1 Rosemount Dohrmann DX2000 Organic Halide Analyzer Operator's Manual (Manual 915349, revision B, December 1993) 13.2 AMDT-M-2 Fluoride Measurement by Means of an Orion EA940 Expandable Ion Analyzer 13.3 AMDT-EP-3 Routine Maintenance of a Modified Dohrmann DX2000 Organic Halide Analyzer 14.0 R E V ISIO N S__________________________________________________________ Revision Number Reason for Change Revision Date 6 ' V0 Q 2 5 7 3M Environmental Laboratory M ethod Fluoride M easurement by Means o f an Orion EA940 Expandable Ion Analyzer Method Identification Number: AMDT-M-2 Revision Number: 0 Adoption Date: Revision Date: None Author: Rich Youngblom Approved By: Grodt/ Leader L/ /?

A new pipette is to be used for each sample. 8.0 C A L IB R A T IO N AND STA N D A R D IZA TIO N ___________________________ 8.1 Preparation of Calibration Standards 8.1.1 The standards required for each project will need to be appropriate for that individual project. Refer to protocol for that project. 8.1.2 Typically 50-500 ppm FC-95 in methanol standards are used. 8.1.3 For rabbit serum studies, use beef serum as the matrix. 8.2 Calibration - Overview The normal calibration is the fluoride curve (AMDT-M-2). However, if an optional spiked serum curve is required the procedure listed below is used. 8.2.1 A calibration curve for the DX2000 is generated by spiking samples with known standards and combusting them using the same methods and matrix type as the samples to be tested. 8.2.2 Typically, three replicates of each standard and five concentrations of standards will be spiked. 8.2.3 Standard curve will be plotted as Mass Spiked F (ug) on the x-axis and Standard Mass Recovered F (ug) on the y-axis. Generate a regression curve and calculate the equation for the line and the r^ value. 8.2.4 Mass Spiked F (ug) = (Amount spiked in mL) x ( Cone, of standard in ppm) x (0.6004)* *FC-95 is 60.04% F therefore 0.6004 is the factor used to convert FC-95 to F 8.2.5 Standard Mass Recovered F (ug) = (TISAB volume in mL) x (Orion reading in ppm) 8.3 Calibration - Procedure 8.3.1 Start Up 8.3.1.1 Run 2 or more Clean Cycles when starting instrument each day. More clean cycles may be used if the previous samples contained high concentrations of fluoride. 8.3.2 Blanks 8.3.2.1 Prepare sample using the same methods and type of matrix as the test sample. 8.3.2.2 For rabbit studies, use beef serum as the matrix. 8.3.2.3 Put serum blank in Dohrmann boat. Combust sample as described in section 9.0 and analyze sample according to method AMDT-M-2 for the ion selective electrode analysis. 8.3.2.4 For rabbit studies, the meter reading for a blank sample should be 0.03 ppm or lower before proceeding with the calibration. Bum samples until this limit is reached, or until in the judgement of the operator the reading is stable with respect to historical readings (previous 48 hours). 8.3.2.5 For non-rabbit studies, the blank readings should reach a predetermined ion concentration before proceeding with the calibration. 8.3.2.6 It may be necessary to mix approximately 50 mg of charcoal with the sample to aid combustion. 8.3.3 Standard Curve 8.3.3.1 If beef serum is frozen, thaw at least enough to complete the standard curve analysis for the day (=30 mL). 8.3.3.2 Pipette 100|iL of beef serum into Dohrmann sample boat. 8.3.3.3 Start with the lowest standard concentration. Using a Hamilton syringe, eject a fixed quantity of the standard on or in the matrix. For rabbit studies, use 4 uL of standard and eject it on or in the beef serum. 8.3.3.4 At least 3 replicates should be used for the lowest standard concentration; more replicates may be used at the discretion of the analyst. 8.3.3.5 Combust the sample as described in section 9.3 and analyze according to AMDT-M-2. 8.3.3.6 Run all 15 standards. If one replicate is significantly different from the other two replicates, run another sample for that standard. Indicate in data that the new replicate replaces the old replicate and that the new replicate will be used to calculate the regression curve. 8.3.3.7 When all standards have been run, calculate the r^. r^ must be at least 0.95. If it is not at least 0.95, consult with supervisor. 8.3.3.8 A new standard curve should be run when the combustion tube or sample matrix is changed. New standard curve may also be run at the discretion of the analyst. 8.4 Storage Conditions for Standards 8.4.1 Storage requirements for standards are dependent on the individual standards used. Typically, standards are stored at room temperature in plastic screw top bottles. 8.4.2 New FC-95 standards should be prepared at least once a month. 9.0 PR O C E D U R E S____________________ ________________________________ 9.1 Typical Operating Conditions: 9.1.1 Combustion tube temperature = 950C. 9.1.2 Oxygen and Helium flow = 50 cc/minute. 9.1.3 Vaporization/Drying time = 240 seconds. 9.1.4 Bake time = 300 seconds. 9.2 Start Up Procedure: 9.2.1 If the program is not started, start the EOX program on the PC. 9.2.2 Open the SYSTEM SETUP window. 9.2.3 Put the furnace module and the cell in the READY mode. 9.2.4 Close the SYSTEM SETUP window. 9.2.5 When the oven has reached the READY temperature, run the CLEAN BOAT program found in the CELL CHECK menu. 9.2.6 See AMDT-EP-3 for details of the Dohrmann software. 9.3 Sample Extraction Procedure: 9.3.1 Open the SAMPLE HATCH and pipette lOOpL of sample into the BOAT. It may be necessary to mix approximately 50 mg of charcoal with the sample to aid combustion. If this is done, charcoal should also be mixed in while establishing the baseline and when generating the standard curve. 9.3.2 Close SAMPLE HATCH. 4 00260^ 9.3.3 Add appropriate volume of TISAB solution or 1:1 TISAB:Milli-QTM water mixture to a labeled sample collection vial. Typically 0.6 mL to 15 mJL are used. For rabbit studies, use 1.0 or 2.0 mL of 1:1 TISAB:Milli-QTM water mixture. 9.3.4 Place the vial so that the tip of the COMBUSTION TUBE is in the TISAB at least 0.25 inches. Gases released during pyrolysis must bubble through the TISAB. 9.3.5 Run the EOX-WATER program found in the RUN menu. 9.3.6 When the EOX program is finished, remove the collection vial from the combustion tube. 9.3.7 If undiluted TISAB was used to collect the sample, add an equal volume of Milli-QTM water to the TISAB to make 1:1 TISAB:Milli-QTM. 9.3.8 Rinse the end of the combustion tube with Milli-QTM water and wipe with a KIMWIPE to remove any TISAB remaining on the tube. 9.3.9 Open the sample hatch and remove any remaining ash from the boat. Ash can be removed with a cotton tipped applicator and/or vacuumed out. It may be necessary to scrap particles off the bottom with a spatula or other similar device. A drop of Milli-QTM water may be added to the boat to aid in the Clean Cycle. 9.3.10 Close the hatch. 9.3.11 Run the CLEAN BOAT program. 9.3.12 Sample is ready for analysis by ion selective electrode (AMDT-M-2). 9.4 Sample Calculations 9.4.1 Use the standard curve to calculate the sample value. 9.4.2 Sample Mass Recovered F (ug) = (TISAB vol in mL) x /Orion reading in ppm - intercept) (Slope) 10.0 V A L ID A T IO N ________________________ 10.1 Quality Control 10.1.1 Daily Start Up Check Samples: Once the standard curve is established, each day of analysis is started by analyzing QC samples. The QC samples are to be the same as the lowest concentration spiked samples used to generate the standard curve. Each concentration must be done in triplicate unless the first two replicates are within 20% of the standard curve, then a third replicate is not necessary. 10.2 Precision and Accuracy: See method development analysis and sample analysis in Fluoride Notebooks 2,3, and 5. Precision and accuracy varies when analyzing samples of different matrices and different reference compounds. 10.3 Other Validation Parameters: NA 11.0 DATA A N A LY SIS__________________________________________ 11.1 Calculations 11.1.1 For the standard curve, use regression analysis in Excel, version 5.0 or greater. 11.1.2 To calculate the fluoride contraction in the sample, see method AMDT-M-2. G0260JU 11.2 Analyzing the Data 11.2.1 must be at least 0.95 or greater. "Outliers" may be excluded if two of the three replicates are within 20% of each other and the outlier is greater than 200% of the average of those two or less than 50% of the average of those two. Any such outliers should be pointed out in the data and noted in the Final Report along with the reason it was considered an outlier. 12.0 A TTA C H M E N T S_____________________________________________________ None 13.0 R EFE R E N C E S________________________________________________________ 13.1 Rosemount Dohrmann DX2000 Organic Halide Analyzer Operator's Manual (Manual 915349, revision B, December 1993) 13.2 AMDT-M-2 Fluoride Measurement by Means of an Orion EA940 Expandable Ion Analyzer 13.3 AMDT-EP-3 Routine Maintenance of a Modified Dohrmann DX2000 Organic Halide Analyzer 14.0 R E V ISIO N S___________________________________________________________ Revision Number Reason for Change Revision Date 6 C0260J 9.3 Quality Assurance Unit Statement 0026040 Attachment D GLP Study Quality Assurance Statement Study Title: Single-dose Intravenous Pharmacokinetic Study of T-6067 in Rabbits Study Number: AMDT-120694.1 Name of Auditor: KariRambo This study has been inspected by the Quality Assurance Unit as indicated in the following table.

G0261jb H W I6329-151 AMDT 120694.1 Dohrmann Serum Analysis Analysis Dates: 07/27/95 - 07/31/95 All serum samples were thermally extracted by a modified Dohrmann D X 2000 Organic Halide Analyzer and collected in a 1:1 milli Q water and TISAB solution. The samples were measured on an Orion EA940 expandable ion analyzer. The Dohrmann was calibrated using 34ppm, 40ppm, 62ppm, lOOppm, 124ppm, 250ppm, and 500ppm FC-95 standards. The Orion was calibrated by direct measurement with no blank correction using 0.05ppm, O.lppm, 0.5ppm, l.Oppm and 1.5ppm F standards. The slope, intercept, and correlation were recorded in die appropriate logbook. A summary table is included, showing the ppm F ` in each sample (see page 2). The value o f "N D " has been entered for any sample with an Orion reading o f below 0.05.

TISAB buffer is added to each sample as it proceeds through the system. The sample then goes through a heated mining coil before the potential between the ion selectiue electrode and the reference electrode is measured. The signal is amplified and related to the fluoride concentration. The instrument was calibrated in the ranges of 0.015 - 0.15 ppm and 0.15 - 1.50 ppm fluoride. The standard curue for the high range was plotted using the inuerse logarithm option. The standard curue for the low range is linear. All standards and samples were then calculated by the Skalar software using these curues. All results below 0.0001 ppm appear on the raw data as # . # # # # . A quality control standard was analyzed euery 10 samples to check for accuracy and drift. Raw data is taken from the appropriate calibrated range of the Skalar printout and summarized on an Excel spreadsheet. The final results are adjusted for the collection uolume and any subsequent dilutions. SUMMARY OF 6329-151 SERUM SAMPLES AMDT 120694.1 OCko W iV 5 Dose Level: 0 F52762 1.56 6.18 ND 3.96 3.44 1.43
