Study Title: 
A Phase 1, Open-label, Randomized, Two-period, Two-treatment, Crossover Study to 
Evaluate the Effect of Exenatide on the Pharmacokinetics (PK) and Pharmacodynamics (PD) 
of Bexagliflozin in Healthy Subjects. 
Study Number: THR-1442-C-458 
Study Phase: 1 
Primary Objective:  
To evaluate the effect of exenatide injection on the PK and PD of bexagliflozin. 
Secondary Objective: 
To assess the safety and tolerability of bexagliflozin when it is used in combination with 
exenatide.  
Study Design: 
This is a phase 1, single center, open-label, 2 × 2 crossover study designed to assess the 
effects of exenatide injection on the PK and PD of orally administered bexagliflozin tablets. 
Approximately 20 eligible healthy subjects will be randomly assigned to one of the two 
groups (1 or 2) with up to 10 subjects per group. Each group will receive both the treatments 
alternately, in a crossover fashion (two-period, two-treatment crossover design), with the two 
treatment periods separated by a 7-day washout period. In Treatment Period 1, subjects in 
Group 1 will receive a single oral dose of bexagliflozin tablets, 20 mg, alone 30 min before 
breakfast, and subjects in Group 2 will receive subcutaneous injection dose of exenatide at 10 
g twice a day (bid) with initial dosing 30 min prior to a single oral dose of bexagliflozin 
tablets, 20 mg, and 1 h before breakfast and followed by the second dosing of exenatide 
alone 1 h prior to evening meals. In Treatment Period 2, subjects in Group 1 will receive 
subcutaneous injection dose of exenatide at 10 g bid with initial dosing 30 min prior to a 
single oral dose of bexagliflozin tablets, 20 mg, and 1 h before breakfast and followed by the 
second dosing of exenatide alone 1 h prior to evening meals and subjects in Group 2 will 
receive a single oral dose of bexagliflozin tablets, 20 mg, alone 30 min before breakfast. 
Clinical laboratory tests and safety monitoring will be conducted during both treatment

periods.  
In treatment period 1, subjects will be admitted to the clinic on day 0, the day before dosing, 
and will stay in the clinic until 48-h post-dose.  In treatment period 2, subjects will be 
admitted to the clinic on day 7, the day before dosing, and will stay in the clinic until 48-h 
post-dose. Blood samples for bexagliflozin plasma concentrations will be collected at each 
period at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose. 
Urine samples for PD (urinary glucose excretion) analysis will be collected at each period in 
12 h batches at pre-dose (h -12 to 0), and at post-dose at 0 to 12 h, 12 to 24 h, 24 to 36 h, and 
36 to 48 h. 
Study Population:  
Approximately 20 healthy subjects are planned. 
Diagnosis and Main Criteria for Inclusion: 
1. Male and female subjects who are between the ages of 18 and 65 years, inclusive, in 
good health based on medical history, physical examination (PE), electrocardiogram 
(ECG) and routine laboratory tests.

AUC0-extr  % of AUC0-∞  due to extrapolation from tlast to infinity 
Pharmacodynamics Assessments: 
PD parameters include: 
• Urinary glucose excretion (UGE) 
Safety Assessments: 
• Physical examinations (PE) 
• Vital signs 
• 12-lead ECG 
• Clinical laboratory tests including blood chemistry and hematology parameters 
• Urinalysis  
• Adverse events  
Statistical Methods:  
Statistical analysis will be performed using Statistical Analysis Software SAS (SAS Institute 
Inc., USA). PK parameters of bexagliflozin will be calculated using non-compartmental 
analyses (NCA) of plasma concentration-time data. To assess the effect of co-administration 
of exenatide on the PK of bexagliflozin, analyses of variance (ANOVA) using a linear 
mixed-effects model will be fitted to the natural logarithmic transformation of PK parameters 
of bexagliflozin (Cmax, AUC0-t and AUC0-∞). The linear mixed-effects model will include 
subject as a random effect, and treatment, period, and sequence as fixed effects. The 90% 
confidence intervals will be constructed for the ratio of geometric means of PK parameters 
(Cmax, AUC0-t and AUC0-∞) when bexagliflozin is dosed in combination with exenatide 
versus when dosed alone, with 80-125% defined as the lack of interaction boundaries.  
Descriptive statistics for the PK parameters Cmax, tmax, AUC0-∞, AUC0-t, AUC0-extr, CL/F, 
Vz/F, λz, and terminal elimination half-life (t1/2) will be tabulated by treatment. Means, 
standard deviations, medians, ranges (min, max) and geometric means and coefficients of 
variation will be presented for all PK parameters with the exception of tmax. Medians and 
ranges will be presented for tmax.  
Descriptive statistics on the PD parameters will also be performed. Descriptive statistics will 
be used to describe any differences in UGE values between treatment groups.

INTRODUCTION 
The renal Na+/glucose transport protein SGLT2 actively transports extracellular glucose into 
cells using the driving energy of the transmembrane electrochemical potential for sodium 
ions. Individuals with disruptions in SLC5A2, the gene encoding SGLT2, exhibit prominent 
glucosuria in the absence of significant co-morbidities (Santer, Kinner et al. 2003, Kothare, 
Seger et al. 2012); (van den Heuvel, Assink et al. 2002)). The excretion of glucose in the 
urine of diabetic subjects in amounts comparable or greater than that seen in individuals 
harboring loss of functions mutations in SGLT2 has the potential to improve both fasting and 
postprandial hyperglycemia without increasing insulin secretion, causing weight gain, or 
inducing hypoglycemia.  
Bexagliflozin, a candidate oral antidiabetic agent, is a potent and highly specific inhibitor of 
the SGLT2. Bexagliflozin elicits a prominent and predictable glucosuria as demonstrated in 
laboratory animals and in humans. Type 2 diabetes mellitus (T2DM) is a chronic metabolic 
disease. Patients with T2DM often require multiple drug therapy to control the 
hyperglycemia and other comorbidities.  Glucagon-like peptide 1 receptor agonists (GLP-1 
RAs) offer important benefits as monotherapies or in combination with other oral 
antidiabetes drugs (OADs), with low risk for hypoglycemia and significant weight loss by 
enhancing glucose-dependent insulin secretion, suppressing postprandial glucagon release, 
signaling satiety, and slowing gastric emptying. 
Clinical pharmacokinetic (PK) studies have shown that the peak plasma bexagliflozin 
concentrations occurred between 3 to 5 h and thereafter declined in a biphasic manner with 
mean elimination half-life values ranging from 7.80 to 9.71 h. Bexagliflozin is cleared 
predominantly by metabolism to an inactive metabolite, bexagliflozin 3-O-glucuronide by 
the uridine diphosphate glucuronosyltransferase isoform 1A9 (UGT1A9) pathway. Extended 
release bexagliflozin tablet formulations were developed to provide greater than 75% release 
in approximately 8 h in vitro.   
Exenatide is one of most commonly prescribed GLP-1 RAs and is administered 
subcutaneously (SC) twice daily (bid) for its relatively short half-life of 2.4 h. Exenatide is 
primarily eliminated by glomerular filtration and subsequent proteolytic degradation, thus, 
interactions involving cytochrome P450 (CYP450) isoenzymes or enzymes responsible for 
phase II metabolism are not expected. As enzymes responsible for phase II metabolism are 
responsible for the elimination of bexagliflozin, drug-drug interaction between bexagliflozin 
and exenatide is not expected ((U.S. Department of Health  and Human Services February, 
2012). However, because exenatide slows gastric emptying, the rate of absorption for 
concurrent orally administered medications may be altered (Hurren and Pinelli 2012) 
(Kothare, Seger et al. 2012). The objective of this study is to evaluate the effects of 
coadministering exenatide on the pharmacokinetics (PK) and pharmacodynamics (PD) of 
bexagliflozin tablets.

1.1 
Bexagliflozin for the Treatment of Type 2 Diabetes Mellitus 
Bexagliflozin is a highly specific inhibitor of sodium glucose cotransporter 2 (SGLT2) with 
an in vitro IC50 of 2 nM or 0.9 ng/mL and a 2435-fold selectivity for human SGLT2 
compared with sodium glucose cotransporter 1 (SGLT1). Details of the nonclinical and 
clinical findings are described in the Investigator’s Brochure. 
1.1.1 
Summary of Nonclinical Data with Bexagliflozin 
Bexagliflozin exhibits high permeability and is a potential Pgp (p-glycoprotein) substrate and 
inhibitor. It is not a significant inducer or inhibitor of cytochrome P450 isozymes and other 
transporters relevant for drug-drug interactions. 
1.1.2 
Summary of Clinical Data with Bexagliflozin 
Following administration of bexagliflozin tablets in extended release formulations, tmax was 
reached between 3 to 5 h. A 20 mg bexagliflozin tablet produced exposure with a Cmax of 176 
ng/mL or 134 ng/mL and an AUC0-24 of 1199 ng·h/mL or 1087 ng·h/mL in healthy subjects 
when dosing was after or before a meal, respectively. 
The principal metabolites in humans are similar to those found in monkeys and are 
dominated by glucuronides of the parent compound, for which the AUC is >30% relative to 
parent bexagliflozin. Modest accumulation consistent with an extended half-life has been 
seen following multiple daily dosing. Following oral administration of radiolabeled 
bexagliflozin, >90% of the ingested radioactivity was recovered, 51% as fecal excretion and 
41% as urinary excretion. In urine, bexagliflozin accounts for 1.5% of the dose; most of the 
radioactivity is excreted as bexagliflozin 3’-O-glucuronide. The largest fraction of the 
radioactivity in feces is due to bexagliflozin, accounting for about 30% of the administered 
dose. 
The safety and tolerability of bexagliflozin in healthy or diabetic subjects was initially 
evaluated in a single-dose study of up to 100 mg, followed by treatment study in which doses 
ranged from 5 mg/d to 50 mg/d and up to 96 weeks of treatment were evaluated.  Detailed 
information of bexagliflozin clinical experience and potential risks for study subjects are 
provided in the Investigator’s Brochure. 
1.2 
Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and 
Exenatide 
GLP-1 RAs are recommended as an option in patients with T2DM, typically as a second-line 
agent, particularly when weight loss or avoidance of hypoglycemia is a primary 
consideration in the therapeutic strategy. GLP-1 RAs reduce hyperglycemia and promote 
weight loss by enhancing glucose-dependent insulin secretion, suppressing postprandial 
glucagon release, signaling satiety, and slowing gastric emptying. In terms of safety, the most 
common adverse events seen in clinical trials with GLP-1 RAs are of gastrointestinal 
character; mainly nausea, vomiting and diarrhea. However, the incidence diminishes over 
time. Other identified risks include pancreatitis, immunogenicity, acute renal failure and

rapid weight loss. Exenatide is one of most widely prescribed GLP-1 RAs. It was approved 
in 2005 and is administered subcutaneously bid at a maximum approved dose in the United 
States of 10 µg. It is recommended to be taken within 60 minutes of the morning meal and 
within 60 minutes of the evening meal (approximately 6 hours or more apart). 
After subcutaneous administration, exenatide is rapidly absorbed, usually reaching peak 
concentrations 2 h post administration. Peak plasma concentrations of exenatide after a 10 µg 
dose reach approximately 200 pg/mL. Exenatide is primarily eliminated by glomerular 
filtration and subsequent proteolytic degradation. After a single subcutaneous dose, it 
exhibits a short half-life of approximately 2.4 h. PK/PD modeling and empirical assessments 
from early clinical studies supported a twice daily dosing regimen. Because of its relatively 
short half-life, significant systemic accumulation is not observed with repeated twice-daily 
dosing.

INVESTIGATIONAL PLAN 
3.1 
Overall Study Design and Plan 
This single center, phase 1, open-label, 2 × 2 crossover study is designed to assess the effects 
of exenatide injection on the PK and PD of orally administered bexagliflozin tablets. 
Approximately 20 eligible healthy subjects will be randomly assigned to one of the two 
groups (1 or 2) with up to 10 subjects per group. Each group will receive both the treatments 
alternately, in a crossover fashion (two-period, two-treatment crossover design), with the two 
treatment periods separated by a 7-day washout period. In Treatment Period 1, subjects in 
Group 1 will receive a single oral dose of bexagliflozin tablets, 20 mg, alone 30 min before 
breakfast, and subjects in Group 2 will receive subcutaneous injection dose of exenatide at 10 
g bid with initial dosing 30 min prior to a single oral dose of bexagliflozin tablets, 20 mg, 
and 1 h before breakfast and followed by the second dosing of exenatide alone 1 h prior to 
evening meals. In Treatment Period 2, subjects in Group 1 will receive subcutaneous 
injection dose of exenatide at 10 g bid with initial dosing 30 min prior to a single oral dose 
of bexagliflozin tablets, 20 mg, and 1 h before breakfast and followed by the second dosing 
of exenatide alone 1 h prior to evening meals and subjects in Group 2 will receive a single 
oral dose of bexagliflozin tablets, 20 mg, alone 30 min before breakfast.  
Clinical laboratory tests and safety monitoring will be conducted during both treatment 
periods.  
In treatment period 1, subjects will be admitted to the clinic on day 0, the day before dosing, 
and will stay in the clinic until 48 h post-dose. In treatment period 2, subjects will be 
admitted to the clinic on day 7, the day before dosing, and will stay in the clinic until 48 h 
post-dose. Blood samples for bexagliflozin plasma concentrations will be collected at each 
period at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose of 
bexagliflozin. 
Urine samples for PD analysis will be collected at each period in 12 h batch at pre-dose (h -
12 to 0), and at post-dose of bexagliflozin at 0 to 12 h, 12 to 24 h, 24 to 36 h, and 36 to 48 h.  
Sampling time was determined based on previous pilot PK and PD studies. 
For the schedule of study events table, see Appendix 1. For overall dosing schedule, see 
Table 1.  
3.2 
Rationale for Study Design and Control Group 
The primary goal of the study is to assess the safety, tolerability, PK and PD of orally 
administered bexagliflozin tablets when it is concurrently administered with exenatide 
injection in healthy subjects.   
This study is designed to be a two-period, two-treatment, crossover study with a 7-day 
washout period (>10 plasma apparent terminal elimination half-lives for both bexagliflozin 
and exenatide). The crossover study will allow direct comparison of two treatments in the

same subjects. Such an approach eliminates the influence of difference in subject 
characteristics seen in parallel group design. The primary route for excretion of exenatide is 
glomerular filtration and subsequent degradation of peptide bonds. Thus, drug interaction 
involving CYP450 and phase II enzymes are not expected between bexagliflozin and 
exenatide. However, because of slowing of gastric emptying, exenatide is expected to alter 
the absorption of orally administered concomitant medications especially when exenatide is 
administered prior to co-administered drug, typically resulting in a minor reduction of 
maximum plasma concentration (Cmax) and a prolonged time of maximum concentration 
(tmax). Drug exposures are not expected to be significantly altered. In order to observe the 
maximal potential effect of exenatide on the absorption rate of bexagliflozin, bexagliflozin 
will be administered orally 30 min after subcutaneous exenatide injection, at 10 g bid (the 
highest dose approved for use in the United States), meanwhile, the highest dose used (10 g 
bid exenatide injection in the United States) or intended to be used (20 mg bexagliflozin 
tablets) clinically will be selected.   
Previous studies showed that the PK parameters after multiple dosing were consistent with 
those after single doses for both bexagliflozin and exenatide. Thus a single oral dose of 
bexagliflozin tablets will be administered to healthy subjects in this study to evaluate the 
potential drug-drug interaction between bexagliflozin and exenatide. In this protocol, the 
effect of bexagliflozin on PK/PD of exenatide injection will not be measured since the PK of 
exenatide injection is unlikely to be affected by CYP450 and phase II enzymes involved 
pharmacokinetic interactions.    
3.3 
Study Duration and Dates 
This is a phase 1, two-period, two-treatment, crossover study. Subjects will be screened 
within 21 days of the initiation of study drug dosing. Eligible subjects who consent to the 
study will be randomly assigned to 1 of 2 groups, each group will receive both the treatments 
alternately, in a crossover fashion (two-period, two-treatment crossover design), with the two 
treatment periods separated by a 7-day washout period.  
In treatment period 1, subjects will be admitted to the clinic on day 0, the day before dosing, 
and will stay in the clinic until 48 h postdose.  In treatment period 2, subjects will be 
admitted to the clinic on day 7, the day before dosing, and will stay in the clinic until 48 h 
postdose. For details of the schedule and nature of the investigations, see the Schedule of 
Events in Appendix 1.

5.3 
Selection and Timing of Dose for Each Subject 
Dosing order with bexagliflozin alone or in combination with exenatide will be based on 
randomized assignment. Results from pre-clinical data and previous clinical trials indicate 
that the doses of 1.7 mg to 100 mg bexagliflozin are well tolerated and the planned dose of 
20 mg bexagliflozin tablets produced significant glucosuria and is not expected to produce 
serious drug-related adverse events. Subcutaneous exenatide at 10 g bid is the 
recommended clinical dose in patients with T2DM.  
• Bexagliflozin alone: After an overnight fast of at least 10 h, 20 mg bexagliflozin tablets 
will be administered 30 min before the first meal of the day with 240 mL of water. 
• Co-administration of bexagliflozin tablets and exenatide: After an overnight fast of at 
least 10 h, subcutaneous exenatide at 10 g bid will be administered 30 min prior to a 
single oral dose of bexagliflozin and 1 h before breakfast and followed by the second 
dosing of exenatide alone 1 h prior to evening meals. 
 
5.4 
Method of Assigning Subjects to Treatment Groups 
Twenty eligible subjects will be randomly assigned to group 1 or group 2 in a 1:1 ratio. 
Subjects who discontinue the study after randomization for non-safety related reasons may be 
replaced to ensure that the number of evaluable subjects in each group should not be less  
than 8. 
5.5 
Blinding 
This is an open-labeled study. There is no blinding process in this protocol. 
5.6 
Concomitant Therapy 
The participants are not allowed to take any prescription or non-prescription drugs, vitamins, 
or dietary supplements at any time during 14 days prior to (first) drug administration and for 
the duration of each study period. Intermittent use of up to 2 grams per day of acetaminophen 
may be administered if approved by the Investigator or designee. No other concomitant 
medications are permitted with the exception of those required for treatment of an adverse 
event. Subjects may receive any medications for adverse events that are necessary to control 
or minimize the likelihood of more serious adverse events in the investigators’ judgment.  
Concomitant medications administered at the time of randomization and during the study are 
to be recorded on the case report form (CRF).  The medication name, dose, frequency, route 
of administration, dates of administration and reason for administration must be recorded.    
Medications that a subject receives after entering the study and prior to randomization must 
be recorded in the CRF.

5.10 Storage and Accountability 
Bexagliflozin tablets should be stored below 30°C in a secure area with access limited to 
authorized personnel. The sponsor will perform an ongoing inventory of study products. The 
responsible pharmacist must keep a careful inventory of drug shipments received and the 
number of tablets dispensed per study subject. A full reconciliation of drug inventory will be 
performed at the end of the study and the results of this inventory must be recorded in the

6.4 
Vital Signs 
Vitals signs, including pulse, systolic and diastolic blood pressure (BP) in a seated position 
will be obtained after a subject has been sitting for 5 min, respiration rate (RR), and oral 
temperature, will be measured at the scheduled visits described in Appendix 1. BP measures 
will be obtained using a calibrated sphygmomanometer or calibrated automated vitals 
machine. 
Vital signs should be measured prior to blood draws. 
Respiration rate should be measured after at least 5 min of rest. Devices designed to measure 
BP from the finger or wrist may not be used. 
6.5 
Electrocardiography  
6.5.1 
12-Lead Electrocardiograms 
A 12-lead electrocardiogram (ECG) will be conducted as listed in Appendix 1 and whenever 
clinically indicated. 
This procedure should be performed in the supine position after at least 10 min of rest. ECG 
parameters measured will be the RR interval, PR interval, QRS duration, and QT. Each ECG 
should also be assessed by the investigator for signs of ischemia, clinically significant 
hypertrophy, and clinically significant T-wave abnormalities. 
It is the investigator or designee’s responsibility to review the results of the ECG as they 
become available. For each abnormal ECG result, the investigator needs to ascertain if this is 
a clinically significant change from the screening ECG for that individual subject (this 
determination, however, does not necessarily need to be made the first time an abnormal 
result is observed. The investigator may repeat the ECG to verify the results of the original 
result). If the ECG result is determined to be a clinically significant and abnormal change 
from baseline for that subject, this is considered an AE. 
6.6 
Clinical Laboratory Tests 
6.6.1 
Laboratory Parameters 
Subjects will be in a seated, semi-recumbent or supine position during blood collection. 
Clinical blood chemistry and hematology will be performed at the scheduled visits 
(Appendix 1).  Blood samples should be drawn after overnight fasting. The details of the 
required laboratory tests are listed in Table 2.

Sample Collection, Storage, and Shipping 
6.6.2.1 
Hematology and Blood Chemistry 
Blood samples for hematology and chemistry will be collected. Timing of collection is 
described in Schedule of Events (see Appendix 1). 
6.6.2.2 
Urinalysis 
Clean-catch, midstream urine samples will be collected per schedule outlined in Section 7 
and in Appendix 1. Dipstick urinalysis will be conducted.  Microscopy will be obtained if the 
subject has a positive result on leukocytes esterase or nitrites dipstick tests that require 
microscopic follow-up to clarify their significance. In addition, urinalysis will be performed 
from clean catch urine sample at any time in subjects with symptoms of urinary tract 
infection (UTI) or pyelonephritis.  
6.6.2.3 
Urine Collection for PD (UGE)  
Pre-dose urine samples must be collected from -12 to 0 h for baseline measurement of UGE. 
Post-dose urine will be collected without preservative in four batches: 0 to 12 h, 12 to 24 h, 
24 to 36 h, and 36 to 48 h collections. Urine must be refrigerated at 2 to 8oC during 
collection.  After collection, the total volume of each batch and collection time will be 
recorded. Aliquots will be prepared from well mixed collections for the PD of bexagliflozin. 
6.6.2.4 
Plasma Sample Collection for PK  
Whole venous blood samples of 3 mL will be collected from a peripheral vein at each period 
at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose of 
bexagliflozin. Samples will be placed in tubes containing potassium 
ethylenediaminetetraacetic acid (K2EDTA) and stored on ice until centrifuged under 
refrigeration for at least 10 min at 3,000 rpm.  After centrifugation, plasma will be removed 
and stored frozen in aliquot at or below -20°C. Processed frozen plasma samples will be 
transferred on dry ice to the analytical laboratory and will be stored at or below -20oC until 
analysis.

Cmax and tmax will be obtained directly from experimental observations. If multiple maxima 
occurred at equal concentrations, the first temporal value will be taken. 
The apparent terminal half-life, t1/2, where determinable, will be calculated as the natural log 
of 2 divided by the terminal phase rate constant, λz. The number of data points included in 
the regression will be determined by visual inspection, but a minimum of three data points in 
the terminal phase, excluding Cmax, is required to estimate λz. In order for the selection to 
take place the adjusted r2 value reported in Phoenix®WinNonlin® must be above 0.7. 
AUC0-t and AUC0-∞ will be calculated using the linear trapezoidal rule, using actual elapsed 
time values. If the actual time of sample collection is not available the nominal time may be 
used for the purposes of parameter estimation. For the purpose of calculating AUC, all 
missing values will be treated as missing in the PK analysis and excluded from analysis 
except when they occur at pre-dose where they will be set to zero. All values that were below

the limit of quantitation (BLOQ) prior to tmax will be set to zero. BLOQ values that occur 
after tmax will be set to missing. When ≥ 2 consecutive plasma concentrations below the limit 
of quantitation (BLOQ) are encountered after tmax, these and all subsequent values will be 
excluded from the analysis.  
AUC0-∞ will be calculated according to the following equation: 
AUC0-∞= AUClast + (Clast / λz), where Clast is the last temporal quantifiable plasma 
concentration. 
The proportion of AUC0-∞ due to extrapolation (AUC0-extr) will be calculated, expressed as a 
percentage and reported. AUC0-∞ values will be considered unreliable estimates if the AUC0-
extr is greater than 20%. 
CL/F will be calculated as Dose/AUC0-∞ 
Vz/F will be calculated as Dose/(λz × AUC0-∞) 
Descriptive statistics for the plasma concentrations of bexagliflozin by Treatment and 
Timepoint will be provided. A listing of plasma concentrations by Subject, Treatment 
Period and Timepoint will also be provided.

Pharmacodynamic Assessment 
Urinary glucose excretion (UGE) will be determined as the PD parameter. Urinary creatinine 
will be determined to calculate the creatinine normalized UGE. 
6.9 
Adverse Events Assessments 
Adverse event (AE): Any untoward medical occurrence in clinical investigation subject 
administered a pharmaceutical product. An AE does not necessarily have to have a causal 
relationship with this treatment. 
Serious adverse event (SAE): A serious adverse event (experience) or reaction is any 
untoward medical occurrence that at any dose: 
• results in death, 
• is life-threatening (NOTE: The term "life-threatening" in the definition of "serious" refers 
to an event in which the patient was at risk of death at the time of the event and does not 
refer to an event which hypothetically might have caused death if it were more severe.), 
• requires inpatient hospitalization or prolongation of existing hospitalization, 
• results in persistent or significant disability/incapacity, 
• is a congenital anomaly/birth defect, 
• is an important medical event. 
 
An important medical event is an event that may not be immediately life-threatening or result 
in death or hospitalization but may jeopardize the patient or may require intervention to

prevent one of the other outcomes listed in the definition above. Examples of such events are 
intensive treatment in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalization, or development of drug 
dependency or drug abuse. 
Non-serious adverse events are all events that do not meet the criteria for a "serious" adverse 
event. 
Immediately Reportable Adverse Event (IRAE): Any serious adverse event or any 
adverse event that necessitates discontinuation of investigational product. 
Clinical Laboratory Changes: It is the investigator’s responsibility to review the results of 
all laboratory tests as they become available. For each abnormal laboratory test result, the 
investigator needs to ascertain if this is a clinically significant change from baseline for that 
individual subject. This determination, however, does not necessarily need to be made the 
first time an abnormal value is observed. The investigator may repeat the laboratory test or 
request additional tests to verify the results of the original laboratory tests. If this laboratory 
value is determined to be an abnormal change from baseline for that subject, this is 
considered an AE. 
Hypoglycemia will be defined as any fasting plasma glucose (FPG) value < 70 mg/dL and 
documented as described in Section 6.9.4.4. 
Any increase in liver function tests (AST, ALT, or bilirubin) greater than 3 times the upper 
limit of normal (ULN) for the laboratory utilized will be considered a clinical laboratory 
adverse event. 
An increase in creatinine from baseline by 0.5 mg/dL or more will be reported as a laboratory 
adverse event. 
Severity: Adverse events will be graded on a 3-point scale and reported as indicated on the 
CRF. The intensity of an adverse experience is defined as follows: 
1 = Mild: discomfort noticed, but no disruption to daily activity 
2 = Moderate: discomfort sufficient to reduce or affect normal daily activity 
3 = Severe: inability to work or perform normal daily activity 
Investigational Product Causality: The site and database should ask for the causality 
relative to the study compound. Relationship of an adverse event to dosing will be assessed 
as follows: 
Definite: There is a reasonable causal relationship between the investigational product and 
the AE when the event responds to withdrawal of the investigational product (dechallenge), 
and recurs with administration of the investigational product (rechallenge).

Page 31 of 54 
Probable: There is a reasonable causal relationship between the investigational product and 
the AE. The event responds to dechallenge. Rechallenge is not required. 
Possible: There is a reasonable causal relationship between the investigational product and 
the AE. Dechallenge is lacking or unclear. 
Not Likely: There is a temporal relationship to investigational product administration, but 
there is not a reasonable causal relationship between the investigational product and the 
event. 
Unrelated: There is no temporal or causal relationship to investigational product 
administration. 
6.9.1 
Collecting and Reporting Adverse Events 
The investigator or designee will periodically assess subjects for the occurrence of adverse 
events. To avoid bias in collecting information about adverse events, the investigator or 
designee should ask subjects the following question: "How have you felt since you were last 
checked?" All adverse events (serious and non-serious) reported by the subject must be 
recorded on the source documents and CRFs provided by the sponsor. 
In addition, Theracos’ Medical Monitor or its designated personnel must be notified 
immediately by telephone or fax of any immediately reportable adverse events according to 
the procedure outlined below. Special attention should be paid to recording hospitalization 
and concomitant medications. 
6.9.2 
Immediately Reportable Adverse Events 
The investigator or designee must report any serious adverse event (SAE), by telephone, 
email, or fax, to Theracos or its representative immediately after the investigator or study 
staff becomes aware of the event. An immediately reportable adverse event (IRAE) form 
should be completed and sent by email or fax or overnight courier to the sponsor within 24 h 
of knowledge of the event. 
Non-serious events that require discontinuation of investigational product (including 
laboratory abnormalities) should be reported to Theracos within 3 working days. The IRAE 
form should be completed and sent by email or fax or overnight courier to the sponsor. 
Subjects experiencing an SAE should be followed clinically until their health has returned to 
baseline status or until all parameters have returned to normal, or have otherwise been 
explained. It is expected that the investigator will provide or arrange appropriate supportive 
care for the subject.

6.9.3 
Pregnancy 
Women of childbearing potential (WOCBP) who are sexually active must use an effective 
method of birth control during the course of the study, in a manner such that risk of failure is 
minimized. 
Before enrolling WOCBP in this clinical trial, investigators must review guidelines about 
study participation for WOCBP. The topics should generally include: 
1. General information. 
2. Informed consent form. 
3. Pregnancy prevention information. 
4. Drug interactions with hormonal contraceptives. 
5. Contraceptives in current use. 
6. Guidelines for the follow-up of a reported pregnancy. 
 
Prior to study enrollment, WOCBP must be advised of the importance of avoiding pregnancy 
during trial participation and the potential risk factors for an unintentional pregnancy. The 
subject must sign an informed consent form stating the above-mentioned risk factors and that 
the consequences were discussed with her. 
During the study, all WOCBP should be instructed to contact the investigator or designated 
study staff immediately if they suspect they might be pregnant (e.g., missed or late menstrual 
cycle). 
If a subject, investigator or designee suspects that the subject may be pregnant prior to 
investigational product administration, the investigational product administration must be 
withheld until the results of serum pregnancy tests are available. If the pregnancy is 
confirmed, the subject must not receive the investigational product and must not remain in or 
be enrolled in the study. 
The investigator or designee must notify the Medical Monitor within 3 working days of the 
receipt of information that any female subject who has become pregnant.  
The investigator or designee must record the event on the Pregnancy Surveillance form and 
forward it to the sponsor’s clinical or designated personnel. 
6.9.4 
Follow-up of Adverse Events  
6.9.4.1 
Follow-up of Non-serious Adverse Events 
Non-serious adverse events that are identified on the last scheduled contact must be recorded 
on the AE CRF with the current status noted.  All non-serious events that are ongoing at the 
time will be recorded as ongoing on the CRF.

6.9.4.2 
Follow-up of Post-Study Serious Adverse Events 
SAEs that are identified on the last scheduled contact must be recorded on the AE CRF page 
and reported to Theracos according to the reporting procedures outlined in Section 6.9.1. 
These may include unresolved previously reported SAEs, or new SAEs. The investigator or 
designee should follow these subjects until the events are resolved, or the subject is lost to 
follow-up. Resolution means the subject has returned to the baseline state of health, or the 
investigator does not expect any further improvement or worsening of the subject’s 
condition. The investigator or designee should continue to report any significant follow-up 
information to Theracos until the event has been resolved. 
Any new SAEs reported by the subject to the investigator that occur after the last scheduled 
contact, and are determined by the investigator to be reasonably associated with the use of 
the investigational product, should be reported to the Medical Monitor or the sponsor’s 
designated personnel. These may include SAEs that are captured on follow-up telephone 
contact or at any other time point after the defined study period (i.e., up to last scheduled 
contact). The investigator or designee should follow subjects with SAEs identified after the 
last scheduled contact until the events are resolved, or the subject is lost to follow-up. The 
investigator or designee should continue to report any significant follow-up information to 
the Sponsor until the event has been resolved. 
6.9.4.3 
Hepatotoxicity 
Any clinically significant increase in hepatic enzymes and specifically ALT or AST ≥3x 
ULN requires immediate repeat test within 48 to 72 h to confirm the hepatic enzyme 
elevation. Study medication should be stopped and the event should be reported as an 
adverse event within the CRF if the enzyme elevation is confirmed or worsening. Potential 
contributors to hepatic enzyme elevation should be evaluated by the investigator. The 
investigator is encouraged to consult with the Medical Monitor regarding ongoing diagnostic 
workup. 
Investigational product should be permanently discontinued if any of the following criteria is 
met: 
• ALT or AST > 8xULN, 
• ALT or AST > 3xULN and (total bilirubin > 2xULN or INR > 1.5), 
• ALT or AST > 3xULN with the appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (> 5%). 
 
6.9.4.4 
Hypoglycemia 
Hypoglycemia will be recorded under 5 categories: 
• Critical hypoglycemia: An event requiring assistance of another person to actively 
administer carbohydrate, glucagons, or other resuscitative actions. These episodes may be 
associated with sufficient neuroglycopenia to induce seizure or coma. Plasma glucose

measurements may not be available during such an event, but neurological recovery 
attributable to the restoration of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration. All such 
events should be recorded as serious adverse events in the CRF. 
• Documented symptomatic hypoglycemia: An event during which typical symptoms of 
hypoglycemia are accompanied by a measured plasma glucose concentration ≤ 70 mg/dL 
(3.9 mmol/L). 
• Asymptomatic hypoglycemia: An event not accompanied by typical symptoms of 
hypoglycemia but with a measured plasma glucose concentration ≤ 70 mg/dL (3.9 
mmol/L). 
• Probable symptomatic hypoglycemia: An event during which symptoms of hypoglycemia 
are not accompanied by a plasma glucose determination but that was presumably caused 
by a plasma glucose concentration ≤70 mg/dL (3.9 mmol/L). 
• Relative hypoglycemia: An event during which the subjects report any of the typical 
symptoms of hypoglycemia, and interprets those as indicative of hypoglycemia, but with 
a measured plasma glucose concentration > 70 mg/dL (3.9 mmol/L). 
 
If a subject experiences symptomatic hypoglycemia, confirmed by point-of-care glucose 
monitoring at the time of symptoms with a blood sugar level < 70 mg/dL (3.9 mmol/L), the 
subject should be treated with 15 to 20 grams of oral glucose or simple carbohydrate (glucose 
tablets, raisins, orange juice, glucose-containing soda, or soft sugar candies).  
If a subject with symptomatic hypoglycemia is unable to self-administer glucose tablets, 
candies, or glucose-containing solutions, then the appropriate study staff should administer 
either intramuscularly or subcutaneously a single injection of 1.0 mg of glucagon. A single 
dose of glucagon should restore consciousness within approximately fifteen minutes. Failure 
to correct hypoglycemia within this timeframe or observation by appropriate study staff of 
profound low sugar with accompanying coma or seizure will be treated by intravenous 
infusion of 5% dextrose.  
Blood glucose monitoring will be done by appropriate study staff using a point-of-care 
glucose monitor beginning at the time of hypoglycemia detection and continue every fifteen 
minutes, or more frequently if required, until that time that the subject’s level of alertness has 
returned to appropriate levels and point-of-care glucose levels are above 70 mg/dL.  
6.10 Concomitant Medication Assessments 
A concomitant medication is any medication the subject enters the trial taking and is 
expected to continue taking for some portion of the trial, as well as any medication other than 
the investigational product that the subject takes during the course of the trial. All 
prescription and over-the-counter medications, including vitamins and herbal supplements, 
that subjects receive during the trial must be documented on the CRF. This documentation 
should continue until the subjects are discharged.

therapeutic chemical classification (ATC) and preferred name will be produced.  A listing of 
concomitant medications will include all medications taken by any subjects during the course 
of the study. 
Concomitant medications administered during the study are to be recorded on the CRF.  The 
medication name, dose, frequency, route of administration, date(s) of administration and 
reason for administration must be recorded.  This documentation should continue until 
discharge from the study. 
6.11 Removal of Subjects from the Trial or Study Drug 
The investigator or designee must emphasize to potential subjects the importance of 
continued participation for the full duration of the trial during the informed consent process. 
Participation in the study is voluntary. A participant has the right to withdraw from the study 
at any moment for any reason. The investigator will be informed immediately. 
The investigator has the right to terminate participation of a subject in case it is difficult to 
obtain blood samples, in case of violation of the protocol or in case of severe or serious 
adverse events. 
In case a subject withdraws from the study, the study monitor will be informed immediately. 
If there is a medical reason for withdrawal, the volunteer should remain under the 
supervision of the medical investigator until satisfactory health returns. 
Subjects who discontinue the active dosing phase of the study due to adverse event(s) or 
other safety concerns will not be replaced. 
When the decision is made to discontinue a subject’s participation in the study, no further 
investigational product medication should be administered. Every attempt should be made to 
complete all required study evaluations and procedures. Reasons for all withdrawals should 
be recorded on the CRF. 
The investigator may withdraw a subject from the THR-1442-C-458 trial for any of the 
following reasons: 
• A protocol violation occurs, 
• A serious or intolerable adverse event occurs, 
• A clinically significant change in a laboratory parameter occurs, 
• The sponsor or investigator terminates the study, or 
• The subject requests to be discontinued from the study. 
 
Subjects who do not complete the study but who have received investigational product 
should have a follow-up examination, including a complete physical examination, vital signs, 
ECG and clinical laboratory tests if clinically indicated according to Section 7.

PLANNED STATISTICAL METHODS 
9.1 
General Considerations 
The statistical evaluation of pharmacokinetic and pharmacodynamic parameters will be 
conducted by the designated CRO. A detailed Statistical and Analytical Plan will be 
generated prior to initiation of the study. Statistical analysis will be performed using 
Statistical Analysis Software SAS (SAS Institute Inc., USA). Non-compartmental analysis 
will be performed using Phoenix® WinNonlin® 6.4 (Certara, USA). 
9.2 
Determination of Sample Size 
The sample size for this study is not based upon formal statistical consideration. The sample 
size is considered adequate to characterize the PK of bexagliflozin, to assess potential drug-
drug interactions and to provide safety and tolerability data on bexagliflozin when 
administered with exenatide. 
9.3 
Analysis Populations 
Statistical analysis populations will include: 
Safety: The safety population will include all randomized subjects who receive at least one 
dose of the drug.  Subjects will be analyzed according to the treatment received. 
PK: The PK population will include all randomized subjects who receive study drug and who 
have sufficient plasma bexagliflozin measurements to derive at least one PK parameter 
following dosing. The PK population will be used to summarize the PK parameters. 
PD: The PD population will include all randomized subjects who receive study drug and will 
have had at least 2 batches of 12 h urine collection from which to calculate UGE 
measurement following dosing. The PD population will be used to summarize the PD 
parameters. 
9.4 
Demographics and Baseline Characteristics 
Baseline characteristics will be descriptively summarized for all subjects in the safety and the 
PK or PD populations. No statistical tests will be performed. 
9.5 
Statistical Analysis of Pharmacokinetic Variables 
To assess the effect of co-administration of exenatide on the PK of bexagliflozin, analyses of 
variance (ANOVA) using a linear mixed-effects model will be fitted to the natural 
logarithmic transformation of PK parameters of bexagliflozin (Cmax, AUC0-t and AUC0-∞). 
The linear mixed-effects model will include subject as a random effect, and treatment, 
period, and sequence as fixed effects. The 90% confidence intervals will be constructed for 
the ratio of the least squares (LS) geometric means of PK parameters (Cmax, AUC0-t and

AUC0-∞) when bexagliflozin is dosed in combination with exenatide versus when dosed 
alone, with 80-125% defined as the lack of interaction boundaries.  
Descriptive statistics for the PK parameters Cmax, tmax, AUC0-∞, AUC0-t, AUC0-extr, CL/F, 
Vz/F, λz, and terminal elimination half-life (t1/2) will be tabulated by treatment. Means, 
standard deviations, medians, ranges (min, max) and geometric means and coefficients of 
variation will be presented for all PK parameters with the exception of tmax. Medians and 
ranges will be presented for tmax.  
A listing of derived PK parameters of bexagliflozin by Subject and Treatment Period will be 
provided.  
9.6 
Pharmacodynamic Assessments 
UGE and urinary creatinine will be assessed before first dosing and at the end of each 
treatment period.   
UGE, including UGEt1-t2 and the total 0-24, 24-48 and 0-48 h UGE, will be determined. 
UGEt1-t2 (mg) will be derived from urine volume (Vt1-t2 , mL) × glucose concentration 
(mg/dL) ÷ 100. Parameters normalized for urinary creatinine excretion will also be 
determined. UGE0-12h , UGE12-24h , UGE24-36h, UGE36-48h and the total 48 h UGE will be listed 
and presented in by subject listing and in summary tables for each group. 
UGE in 12 h intervals up to 48 h post-dose, including the baseline, will be graphically 
presented against the corresponding treatment, bexagliflozin alone, and combination with 
exenatide. 
The descriptive statistics will be used to describe any differences in UGE values between 
treatment groups.  
9.7 
Safety Analysis 
Safety data include adverse events (AEs), physical exam results, vital signs, ECG results, and 
clinical lab results, including serum chemistry, hematology, and urinalysis. Observed data 
will be described as counts and percentages for discrete variables and estimation of means, 
standard deviations (SDs), medians, inter-quartile range, minimum and maximum for 
continuous metrics.  All subjects in the safety population will be included in the safety 
analyses.  All safety data will be presented in by-subject listings and included in the clinical 
trial report. 
9.7.1 
Adverse Events 
Adverse events will be mapped to preferred term and body system using the Medical 
Dictionary for Regulatory Activities (MedDRA).  In treatment period 1, 10 subjects in group 
1 will receive a single oral dose of 20 mg bexagliflozin and in treatment period 2 another 10 
subjects will receive the same dosing. As a result, a total of 20 subjects will receive a single 
oral dose of bexagliflozin alone. Likewise, a total of 20 subjects will receive a co-
administration of bexagliflozin and exenatide. The number and percentage of subjects

reporting adverse events will be determined by relationship to dosing and by severity of the 
event.  Drug-related adverse events will be considered those to be at least possibly related to 
bexagliflozin and/or exenatide administration. 
Adverse event listings will be provided for the following subsets: 
• all treatment emergent AEs (TEAEs) 
• all TEAEs at least possibly related to bexagliflozin or exenatide 
• serious TEAEs (if any) 
• TEAEs leading to study discontinuation (if any). 
 
AEs are treatment emergent if they occur on or after bexagliflozin and/or exenatide 
administration. TEAEs will be considered at least possibly related to bexagliflozin or 
exenatide based on the investigator’s assessment.  Only TEAEs will be tabulated in summary 
tables. If the AE(s) onset date-time or date occurs after the first dose up until right before the 
next dose, the AE(s) will be assigned to the first treatment. Any AE(s) that occur after the 
second dose up until the follow-up visit will be assigned to the second treatment. 
Tabulations will display TEAEs by severity and relationship to bexagliflozin and/or 
exenatide. 
9.7.2 
Hypoglycemia  
Hypoglycemia as defined in Section 6.9.4.4 will be presented in listings and summarized. 
9.7.3 
Clinical and Laboratory Events and Analyses 
Clinical and laboratory metrics are measured at baseline and during the treatment.  These 
variables include vital signs (blood pressure, respiration, temperature), clinical laboratory 
results (see Section 6.6 for a complete list), and ECGs. 
Serum chemistry, hematology, and urinalysis (quantitative parameters) data will be 
summarized for each treatment period. Summaries for change from baseline will be 
presented for these laboratory tests. In addition, all serum biochemistry, hematology, and 
urinalysis data outside the reference ranges will be summarized by parameter.  
Laboratory data will be summarized using Low-Normal-High shift tables.  ECG results will 
be summarized as changes from baseline in intervals.  Abnormalities as well as changes from 
previous assessment will be listed.

and contact details of participating investigators, monitors, clinical laboratories, and technical 
departments and/or institutions, as well as information on members of additional study 
committees, will be found in the study files of the investigational site. 
10.2 Institutional Review Board (IRB) or Independent Ethics Committee 
(IEC) Approval 
The study protocol, informed consent document, relevant supporting information, and all 
types of subject recruitment or advertisement information must be submitted to the IRB/IEC 
for review and must be approved by the sponsor and the IRB/IEC before the study is 
initiated.  Any amendments or addenda to the protocol must also be approved by the 
IRB/IEC prior to implementing changes in the study.  The investigator is responsible for 
keeping the IRB/IEC informed of the progress of the study and of any changes made to the 
protocol as deemed appropriate. The investigator must also keep the IRB/IEC informed of 
any SAEs occurring to subjects under their supervision. 
10.3 Ethical Conduct of the Study 
The procedures set out in this protocol pertaining to the conduct, evaluation, and 
documentation of this study are designed to ensure that the sponsor and investigator follow 
Good Clinical Practice Guidelines and the guiding principles detailed in the Declaration of 
Helsinki. The study will also be carried out in keeping with applicable local laws and 
regulations. An inspection by the sponsor representatives and/or their designee and/or healthy 
authority or other authorized regulatory authorities representatives may occur at any time. 
The investigator must agree to the inspection of study-related records by the regulatory 
authority/sponsor representatives, and must allow direct access to source documents to the 
regulatory authority/sponsor representatives. 
The investigator is responsible for complying with the protocol and all appropriate 
regulations and guidelines governing global clinical research. Additionally, he/she is 
responsible for ensuring that all participating staff members are adequately trained and 
competent to perform his/her assigned tasks. 
Modifications to the study protocol will not be implemented by either the sponsor or the 
investigator without agreement by both parties. However, the investigator may implement a 
deviation from or a change of the protocol to eliminate any immediate hazards to the trial 
subjects without prior IRB/IEC or sponsor approval/favorable opinion. As soon as possible, 
the implemented deviation or change, the reasons for it, and if appropriate, the proposed 
protocol amendment should be submitted to the head of the investigational site, IRB (via the 
head of the investigational site) /sponsor.

Any deviations from the protocol must be fully explained and documented by the 
investigator. The circumstances, action taken, and impact of the deviation on the trial must be 
communicated by the principal investigator to the designated medical monitor.  Any 
subsequent actions will be assessed by the designated medical monitor and documented. 
10.4 Subject Information and Consent 
The Investigator will draft the informed consent form based on the protocol and CRO’s draft 
informed consent form. The sponsor will review the investigator’s draft informed consent 
form prior to submission to the IRB/IEC and the final IRB/IEC approved document must be 
provided to the sponsor for regulatory purposes. 
Prior to the beginning of the study, the investigator must have received from the Ethics 
Committee or IRB the written approval or favorable opinion of the informed-consent form 
and any other written information to be provided to subjects.  The written approval of the 
IRB/IEC together with the approved subject information/ informed consent forms must be 
filed.  The informed consent form must contain all elements required by the Food and Drug 
Administration (FDA) under 21 Code of Federal Regulations (CFR) Part 50 and the 
International Conference for Harmonisation (ICH) Good Clinical Practices (GCP) Guidelines 
(E6), in addition to, any other elements required by regulations or institutional policy. 
Written informed consent must be obtained before any study-specific procedure takes place.  
Participation in the study and date of informed consent given by the subject should be 
documented appropriately in the subject’s files.  A copy of the signed informed consent form 
must be provided to the subject.  If applicable, it will be provided in a certified translation in 
the language understood by the subject, if not English.  Signed consent forms must remain in 
each subject’s study file and must be available for verification by study monitors at any time. 
10.5 Subject Confidentiality 
The information obtained during the conduct of this clinical study is confidential, and 
disclosure to third parties other than those noted below is prohibited.  Information obtained 
during the conduct of this study will be used by the sponsor in connection with the 
development of the study drug.  The study investigator is obliged to provide the sponsor with 
complete test results and all data developed in this study.  Subject-specific information may 
be provided to other appropriate medical personnel only with the subject’s permission. To 
ensure compliance with current ICH guidelines, data generated by this study must be 
available for inspection upon request by representatives of national and local health 
authorities, the sponsor, and the IRB/IEC for each study site. 
Subject names and other identifiers, such as photographs, audio, or videotapes, may not be 
disclosed in any publication without prior written authorization from the subject.

10.6 Study Monitoring 
An authorized sponsor representative will conduct site visits to inspect study data, subjects’ 
medical records, and CRFs in accordance with ICH guidelines, GCPs, and the respective 
national and local government regulations and guidelines. 
The investigator will permit authorized representatives of the sponsor and the respective 
national or local health authorities, other authorized regulatory authorities, and IRB to inspect 
facilities and records relevant to this study. 
10.7 Case Report Forms and Study Records 
For each subject consented, a case report form (CRF), in paper or electronic format, will be 
supplied and maintained by the CRO staff and signed by the investigator or authorized 
designee to indicate that he/she has reviewed and agrees with the entered data. This also 
applies to those subjects who fail to complete the trial. The reason a subject is withdrawn 
must be recorded in the case report form. 
Entries made in the CRF must be verifiable against source documents. Source documents are 
defined as all medical records, medical notes, laboratory results, ECG traces and any 
additional document other than the CRF that has original subject information contained 
within it. 
All CRFs and source documents should be completed following GCPs and the CRO’s 
standard operating procedures. 
10.8 Protocol Violations/Deviations 
It is important to conduct the study according to the protocol.  Protocol deviations will not be 
prospectively granted by the sponsor.  If deviations occur, such as a visit or sampling 
window being missed, the investigator must decide whether to proceed, for example, whether 
or not to complete the visit or sample collection outside of the protocol-defined window.  The 
sponsor’s medical monitor must be notified immediately when protocol deviations are 
discovered so that a decision about whether to keep the subject in the study can be made. 
Only when an emergency occurs that requires a departure from the protocol for an individual 
subject will there be such a departure without the sponsor’s pre-approval.  The nature and 
reasons for the protocol deviation will be recorded in the subject’s CRF, and the principal 
investigator must notify the Sponsor. 
Protocol violations must be reported in the final study report. 
10.9 Access to Source Documentation 
Authorized sponsor representatives will conduct site visits to inspect study data, subjects’ 
medical records, and CRFs in accordance with ICH guidelines, GCPs, and the respective 
local and national government regulations and guidelines.

The investigator will permit authorized representatives of the sponsor and the respective 
national or local health authorities, other authorized regulatory authorities, and IRB/IEC to 
inspect facilities and records relevant to this study. 
The center will be visited at regular intervals by a monitor to ensure compliance with the 
study protocol, GCP, and legal aspects. This will include on-site checking of the CRFs for 
completeness and clarity, cross-checking with source documents, and clarification of 
administrative matters. 
All CRF data will be entered into a clinical database.  Following the correction of any errors, 
the clinical database will be locked. 
10.10 Retention of Data 
The study file and all source data should be retained until notification is given by the sponsor 
for destruction. 
If the investigator withdraws from the trial and relinquishes his/her responsibility for the 
maintenance and retention of records, he/she must notify the sponsor in writing so that 
arrangements can be made to properly store the trial materials. 
10.11 Publication and Disclosure Policy 
All data and results and all intellectual-property rights in the data and results derived from 
the study will be the property of the sponsor, who may utilize the data in various ways, such 
as for submission to government regulatory authorities or disclosure to other investigators. 
No publication or disclosure of study results will be permitted except as specified in a 
separate, written agreement between Theracos Sub, LLC and the investigator.  If results of
