Name of Finished Product: 
Bexagliflozin Tablets 
Name of Active Ingredient: 
Bexagliflozin 
Name of Inactive Ingredient: 
Polyethylene oxide, glyceryl behenate, lactose monohydrate, micronized poloxamer 188, 
microcrystalline cellulose, colloidal silicon dioxide, and magnesium stearate. 
Study Title: 
A Phase 1, Open-label, Randomized, Two-period, Two-treatment, Crossover Study to 
Evaluate the Effect of A High-Fat Meal on the Pharmacokinetics of Bexagliflozin in Healthy 
Subjects 
Study Number:THR-1442-C-481 
Study Phase: 1 
Primary Objective:  
• 
To evaluate the effect of a high-fat meal on the pharmacokinetics (PK) of bexagliflozin 
extended release tablets in healthy subjects. 
Secondary Objectives: 
• 
To evaluate the safety of bexagliflozin after a single oral dose in a fasted state and in a 
fed state in healthy subjects. 
• 
To evaluate the effect of a high-fat meal on the potential pharmacodynamic activity of 
bexagliflozin by determining urinary glucose excretion in healthy subjects under fasted 
and fed conditions. 
Study Design: 
This is a phase 1, single center, open-label, 2 × 2 crossover study designed to assess the 
effects of a high-fat meal on the PK of orally administered bexagliflozin tablets, 20 mg. 
Following a ≥ 10-h overnight fast, eighteen (18) eligible healthy subjects will be assigned to 
two groups with an equal number (n=9) of subjects per group to receive a single oral dose of 
bexagliflozin tablets, 20 mg, in either a fasted state or 30 min after starting a high-fat meal. A 
washout period of at least 7 days will be used between the two treatment periods, after which, 
subjects will receive bexagliflozin tablets, 20 mg, in a fasted or fed state (high-fat), 
whichever state they had not received previously. The high-fat meal will be ingested in its 
entirety over an approximate 25-minute period, such that it is completed at least 5 minutes 
prior to the scheduled time of bexagliflozin dosing for the group receiving bexagliflozin with 
food. If a portion of the meal is not consumed, the reason and the amount of remaining food

will be recorded. No food should be allowed for at least 4 h after drug administration. 
Standard meals will be served to both groups 4 hour after dosing.  
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 in each 
period at pre-dose and at 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose. Urine 
collection in 12 h batches will be performed at pre-dose (-12 to 0 h on day 0 and day 7), and 
at post-dose at 0 to 12 h, 12 to 24 h, 24 to 36 h, and 36 to 48 h. 
Clinical laboratory tests and safety monitoring will be conducted during both treatment 
periods. 
Study Population: 
Eighteen healthy subjects are planned to be enrolled and dosed. 
Diagnosis and Main Criteria for Inclusion 
1. Healthy subjects who are between the ages of 18 and 65 years, inclusive. 
2. Subjects with body-mass index (BMI) between 18.0 kg/m2 and 32.0 kg/m2, inclusive.

who agree to refrain from donating sperm and use appropriate birth control such as the 
use of condoms when engaging in sexual intercourse for a period of 30 days after 
discharge from the clinic. 
4. Female subjects of childbearing potential who are willing to use an adequate method of 
contraception and to not become pregnant for the duration of the study. Female subjects 
who are surgically sterile (hysterectomy, oophorectomy) or postmenopausal (absence of 
menses greater than 12 months and age > 45 years) are eligible if they test negative on 
the urine pregnancy test. 
5. Subjects who are non-smokers for at least 3 months prior to screening. 
6. Subjects with adequate venous access at multiple sites in both arms.

Statistical Methods: 
Statistical analysis will be performed using Statistical Analysis Software SAS for Windows® 
(SAS Institute Inc., USA). PK parameters of bexagliflozin will be calculated by non-
compartmental analysis (NCA) of plasma concentration-time data. Non-compartmental 
analysis will be performed using Phoenix® WinNonlin® 6.4 (Certara, USA). To assess the 
effect of a high-fat meal on the PK of bexagliflozin, an 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 fed : fasted ratio of geometric means of 
PK parameters (Cmax, AUC0-t and AUC0-∞), with 80-125% defined as the lack of interaction 
boundaries. 
Descriptive statistics for the PK parameters Cmax, Tmax, AUC0-∞, AUC0-t , 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 exception of Tmax. Medians and ranges will be 
presented for Tmax. 
Descriptive statistics on the PD parameters will be also performed. The effect of high-fat 
meal on the cumulative UGE between subjects under fasted and fed conditions will be 
compared.

INTRODUCTION 
Bexagliflozin, a potent and selective renal Na+/glucose transport protein sodium glucose 
cotransporter 2 (SGLT2) inhibitor is being developed as a treatment for type 2 diabetes 
mellitus. The transport of glucose from the renal tubule into the tubular epithelial cells is 
facilitated by SGLT2 which is expressed primarily in the kidney in the early proximal tubule 
of the nephron (Washburn 2009). By inhibiting SGLT2, bexagliflozin blocks the 
reabsorption of filtered glucose, in turn promoting urinary glucose excretion and thereby 
reducing plasma glucose (Zhang, Welihinda et al. 2011). 
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 are developed to provide greater than 75% release in 
approximately 8 h in vitro. The objective of this study is to evaluate the effects of a high-fat 
meal on the PK of extended release bexagliflozin tablets, 20 mg. 
1.1 
Bexagliflozin for the Treatment of Type 2 Diabetes Mellitus 
Bexagliflozin is a highly specific inhibitor of 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. 
1.2 
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. 
1.3 
 Summary of Clinical Data with Bexagliflozin 
The early clinical studies have been conducted using immediate release (IR) products in 
capsules. Theracos has completed multiple phase 1 studies to evaluate safety, tolerability, 
pharmacokinetics (plasma exposure), pharmacodynamics (glucosuria), and drug metabolism 
in healthy subjects, patients with type 2 diabetes, and diabetic patients with renal impairment.  
Following administration of bexagliflozin IR capsules, time of maximum observed plasma 
concentration (Tmax) was reached within 1 to 3 h. The systemic exposure was dose 
proportional with a maximum observed plasma concentration (Cmax) of 11 ng/mL per mg 
bexagliflozin and an area under the plasma concentration-time curve (AUC0-24) of 
approximately 60 ng·h/mL per mg bexagliflozin in healthy or diabetic subjects. Following 
administration of bexagliflozin tablets in extended release formulations, Tmax was reached 
between 3 to 5 h. The tablets produced dose proportional exposure with a Cmax of 4 or 8

ng/mL per mg bexagliflozin and an AUC0-24 of 40 or 50 ng·h/mL per mg bexagliflozin in 
healthy subjects when dosing was before or after 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 a 4-week treatment study in 
which doses ranged from 5 mg/d to 50 mg/d. The most frequently occurring adverse events 
(AEs) were mild to moderate headache, pollakiuria, nausea, and fatigue. No symptomatic 
hypoglycemia was reported and no treatment-related adverse event led to discontinuation of 
treatment. Extended release tablets of 3 mg to 90 mg strengths were well tolerated in a 
Japanese population with few adverse events reported. 
Detailed information of bexagliflozin clinical experience and potential risks for study 
subjects are provided in the Investigator’s Brochure.

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 a high-fat meal on the PK of orally administered bexagliflozin tablets. Eighteen eligible 
healthy subjects will be randomized into two groups such that an equal number (n=9) of 
subjects will receive a single oral dose of a bexagliflozin tablets, 20 mg, with or without a 
meal on treatment day 1. Subjects randomized to receive bexagliflozin tablets with a high-fat 
meal on day 1 will receive a second dose of bexagliflozin tablets without a meal on treatment 
day 8 after an overnight fast. Subjects randomized to receive bexagliflozin tablets without a 
meal on treatment day 1 after an overnight fast will receive a second dose of bexagliflozin 
tablets with a high-fat meal on treatment day 8. 
Bexagliflozin will be taken orally with 240 mL of water in the morning (approximately 8 
a.m. to 10 a.m.). The time of dosing for a given subject will be the same (as far as 
practicalities permit) in both treatment periods. 
The high-fat meal will follow the FDA guidance (Food Drug Administration 2002) on high-
fat (50% of total caloric content of the meal) and high-caloric (800 to 1000 cal) content. An 
example of the high-fat meal would be two eggs fried in butter, two strips of bacon, two 
slices of toast with butter, four ounces of hash brown potatoes and eight ounces of whole 
milk. Substitutions in this meal can be made as long as the meal provides a similar amount of 
calories from protein, carbohydrate, and fat and has comparable meal volume and viscosity. 
Subjects dosed in the fed state will receive an oral bexagliflozin tablets, 20 mg, 30 min after 
starting to consume a high-fat meal after an overnight fast. No additional food should be 
allowed for at least 4 h post-dose. Water will be allowed as desired except for one hour 
before and after drug administration. The meal will be ingested in its entirety over an 
approximate 25-minute period, such that it is completed at least 5 minutes prior to the 
scheduled time of bexagliflozin dosing for the fed state treatment. If a portion of the meal is 
not consumed, the reason and the amount of remaining food will be recorded. Subjects 
should receive standard meals scheduled at the same time in each period of the study. 
Subjects dosed in the fasting state will receive an oral bexagliflozin tablets, 20 mg, after an 
overnight fast. No food should be allowed for at least 4 h post-dose. Water will be allowed as 
desired except for one hour before and after drug administration. Subjects should receive 
standard meals scheduled at the same time in each period of the study. 
Subjects will be admitted to the clinic on day 0 and day 7, the day before dosing in each 
treatment period, and will stay in the clinic until 48-h post-dose. Standard meals will be 
served at the clinic during the stay. Blood samples (2 mL) for bexagliflozin plasma 
concentrations will be collected at 0 h (pre-dose), and at, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, 
and 48 h post-dose (days 1-3 in treatment period 1 and days 8-10 in treatment period 2 
respectively). Urine collection in 12 h batches will be performed at pre-dose (-12 to 0 h on 
day 0 and day 7), and at post-dose at 0 to 12 h, 12 to 24 h, 24 to 36 h, and 36 to 48 h.

3.2 
Rationale for Study Design 
The PK profile of bexagliflozin formulated as an extended release product at 10 and 30 mg 
has been evaluated in an early clinical trial (THR-1442-C-445). The effects of dose 
administration in the fasted and fed states were assessed in healthy Japanese subjects for 
absorption, distribution, metabolism and excretion of bexagliflozin. Twelve subjects were 
randomized evenly to two dose groups (10 and 30 mg). Each group received first dose of 
bexagliflozin tablets under fed state on day 1, then after 7-day washout, subjects received 
second dose under fasted state. The administration of bexagliflozin at 10 and 30 mg with a 
standard meal resulted in increased average Cmax (range 39% to 59% for bexagliflozin and 
19% to 28% for bexagliflozin 3-O-glucuronide) and decreased half-life (range 23-40% for 
bexagliflozin and 10% to 21% for bexagliflozin 3-O-glucuronide). However, no meaningful 
change in the Tmax of either analyte was observed. No effect of food on the overall systemic 
exposure [area under the plasma concentration-time curve (AUC)] of bexagliflozin and 
bexagliflozin 3-O-glucuronide was observed.  
In general, meals that are high in total calories and fat content are more likely to affect the 
gastrointestinal physiology and thereby result in a maximal effect on the bioavailability of a 
drug substance. Therefore, a high-fat meal will be used in this study to evaluate the potential 
maximum effect of food on the PK of bexagliflozin tablets, 20 mg, which is the intended 
commercial product. The planned sample size in this crossover study will be powered to 
provide sufficient data for a statistical testing of food effect on the PK of bexagliflozin. The 
results will provide a guide for the timing of dosing relative to meals for this bexagliflozin 
product. 
3.3 
Study Duration and Dates 
This is a phase 1, two-period, two-treatment, crossover study. Subjects will be screened 
within 28 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 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 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. The scheduled visits and procedures for each visit are provided in Appendix 1.

STUDY TREATMENTS 
5.1 
Study Drug 
Bexagliflozin tablets, 20 mg, are blue caplet-shaped, film-coated tablets that are intended for 
use in investigational studies in humans. The tablets contain excipients designed to promote 
extended release through a gastroretentive mechanism. The active tablets exhibit a greater 
than 75% release of drug substance by 8 hours in simulated gastric fluid in vitro. 
5.2 
Treatments Administered 
Subjects who consent to be in the study will be randomly assigned to 1 of 2 treatment groups. 
Each group will be dosed with bexagliflozin under a fasted state in one period and under a 
fed state (high fat, high calorie) in the other period. A single oral dose of bexagliflozin 
tablets, 20 mg, will be provided to subjects in each treatment period. 
The detailed dosing schedule is shown in Table 1.

5.3 
Selection and Timing of Dose for Each Subject 
Dosing order with bexagliflozin alone or in combination with food will be based on 
randomized assignment. Results from previous clinical trials indicate that doses of 1.7 mg to 
100 mg of bexagliflozin are well tolerated and the planned dose of bexagliflozin tablets, 20 
mg, produced significant glucosuria and is not expected to produce serious drug-related 
adverse events. 
• 
Bexagliflozin alone: After an overnight fast of at least 10 h, a bexagliflozin tablets, 20 
mg, will be administered 4 h prior to the first meal of the day with 240 mL of water. 
• 
Co-administration of bexagliflozin with food: After an overnight fast of at least 10 h, a 
bexagliflozin tablets, 20 mg, will be administered 30 min after starting to consume a 
high-fat meal with 240 mL water.

If for some reason, a portion of the water is not consumed, the reason and the amount of 
remaining water will be recorded.  
5.4 
Method of Assigning Subjects to Treatment Groups 
A sufficient number of subjects will be screened to ensure that up to 18 subjects will be 
randomized. 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-label 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.  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, date(s) of administration and reason for administration must be recorded.  
This documentation should continue until 1 week from the end of the last study product 
dosing.  Medications that a subject receives after entering the study and prior to 
randomization must be recorded in the CRF. 
5.7 
Restrictions 
5.7.1 
Prior Therapy 
No study subject shall have been dosed with any SGLT2 inhibitor within 3 months prior to 
the screening, nor an investigational drug within 30 days or 7 half-lives, or used any 
prescription medication or herbal supplements within 14 days prior to the first dose of study 
medication. 
5.7.2 
Fluid and Food Intake 
An overnight fast of at least 10 h prior to dosing is required. For the fasting state treatment 
group, oral intake of food (standard meals) will be restricted for 4 h following administration 
of bexagliflozin.

The fed state treatment will consist of a bexagliflozin tablet, 20 mg, taken 30 min after 
subjects start to consume a high-fat (approximately 50% of total caloric content of the meal), 
high-calorie (approximately 800–1000 cal) meal after an overnight fast.  
Each dose will be administered with 240 mL tap water. Food intake will be forbidden during 
the first 4 h post dosing. Water can be allowed as desired except for one hour before and after 
drug administration 
Subjects are expected to consume 100% of the high-fat meal and 240 mL of water provided. 
If a portion of the meal and water is not consumed, the reason and the amount of remaining 
meal and water will be recorded.  
Subjects should receive standard meals scheduled at the same time in each period of the 
study. 
5.7.3 
Subject Activity Restrictions 
Light physical activity is permitted. Subjects should not perform strenuous activity during the 
clinical stay and during the washout period as this could result in elevations of muscle 
creatinine kinase (CK) levels. Smoking during the study is prohibited. 
5.8 
Treatment Compliance 
To ensure compliance, all medication dosing will be supervised by the Investigator or 
qualified staff in the clinic. The exact times of medication dosing will be recorded in the 
CRFs, including a record of checks followed by hand mouth inspection. 
5.9 
Packaging and Labeling 
Investigational product will be provided to the pharmacist or designated site personnel in 
bottles of 90 tablets enclosed with a child-resistant cap. The pharmacist or designated site 
personnel will dispense the investigational products for each subject according to 
randomization assignment. 
5.10 Storage and Accountability 
Bexagliflozin tablets should be stored at controlled room temperature, 15 to 30°C (59 to 
86°F) in a secure area with access limited to authorized personnel. The drug storage facility 
must comply with the medication storage instructions. The trial staff must record the amount 
of investigational product dispensed to each subject in the dosing record. 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 Drug Accountability Form. All unused drug must be returned to a 
sponsor-designated depot after drug accounting is verified by the sponsor or its designee.

STUDY PROCEDURES 
6.1 
Informed Consent 
Before each subject is enrolled in the clinical study, written informed consent will be 
obtained from the subjects according to the regulatory and legal requirements. As part of this 
procedure, the investigator or designee must explain orally and in writing the nature, duration, 
and purpose of the study, and the action of the drug in such a manner that the study subject is 
aware of the potential risks, inconveniences, or AEs that may occur. The investigator should 
educate potential subjects about the scientific importance of their data and the vital role that 
their participation has for the outcome of the entire study. The subject must be informed that 
he/she is free to withdraw from the study at any time. He/She will receive all information that 
is required by federal regulations and International Conference on Harmonisation (ICH) 
guidelines. 
The informed consent document must be signed and dated; one copy will be given to the 
subjects, and the investigator will retain a copy as part of the clinical study records. The 
investigator will not undertake any investigation specifically required for the clinical study 
until written consent has been obtained. The terms of the consent and when it was obtained 
must also be documented. 
6.2 
Medical History 
The following information will be collected at the screening visit: 
• 
Demographic information including age, sex, and race and whether childbearing potential 
if female. 
• 
Significant medical, surgical history and timeframe of the history relative to study 
screening, if applicable. 
• 
Clinically significant history of allergy including drugs and latex. 
• 
History of smoking, alcohol or drug dependence, or abuse in the last 12 months. 
• 
Any blood donation or blood component donation within 4 months. 
• 
Use of any medications including over the counter drugs, vitamins, or dietary 
supplements within 14 days. 
• 
History of vaccination within 30 days prior to the first dose of study medication. 
•

6.3 
Physical Examination 
The investigator or designated qualified individual will perform the physical examinations 
(PEs). A complete physical examination will be performed at screening and at the 
termination visit. Partial physical examinations will be performed at scheduled visits. 
A complete physical examination will include measurement of body weight and height 
(height will be measured only at screening), general assessment of all body systems including 
the skin, head, eyes, ears, nose, throat, neck, lungs, heart, abdomen, lymph nodes, and 
extremities. A partial physical examination will include body weight and an update of the 
general assessment of the skin, heart, lungs and abdomen. 
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. 
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 and Continuous Telemetry Monitoring 
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.

without preservative in four (4) batches: 0 to 12 h, 12 to 24 h, 24 to 36 h, and 36 to 48 h 
collections.  Urine must be refrigerated at 2-8oC during collection.  After collection, the total 
volume of each batch and collection time will be recorded.  A 20 mL aliquot will be prepared 
from well mixed urine collections. The samples will be analyzed for urinary glucose (PD), 
uric acid, creatinine, and electrolytes. 
6.6.2.4 
Plasma Sample Collection for PK  
Whole venous blood samples of 2 mL will be collected from a peripheral vein in each period 
at pre-dose and at 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose. 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 3 aliquots of 200 L 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.

Pharmacokinetic Assessments 
A non-compartmental analysis (NCA) will be used to calculate the PK parameters of 
bexagliflozin using the software Phoenix® WinNonlin® 6.4 (Certara, USA). From the plasma 
bexagliflozin concentration-time data, the following PK parameters will be estimated for 
each subject where feasible. 
Cmax 
Maximum observed plasma concentration 
Tmax 
Time of maximum observed plasma concentration 
z      Terminal elimination phase rate constant 
T½     Apparent terminal elimination half life 
CL/F  Apparent oral clearance 
Vz/F  Apparent volume of distribution 
AUC0-t      Area under the plasma concentration-time curve from Time 0 to Time t (time of 
last quantifiable plasma concentration) 
AUC0-∞ 
Area under the plasma concentration-time curve from Time 0 to infinity 
Cmax and Tmax will be obtained directly from experimental observations. If multiple maxima 
occur at equal concentrations, the first temporal value will be taken. 
The apparent terminal elimination 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 linear interpolation 
method, using actual elapsed time values. If the actual collection time is unknown the 
nominal collection time may be used for the purposes of PK 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 corresponding to Tlast. 
The proportion of AUC0-∞ due to extrapolation (AUCextr) will be calculated and expressed as 
a percentage. AUC0-∞ values will be considered unreliable estimates if the AUCextr is greater 
than 20%. 
CL/F will be calculated as Dose/AUC0-∞. 
Vz/F will be calculated as Dose/(λz × AUC0-∞). 
T½ will be calculated as 0.693/λz. 
Descriptive statistics for the plasma concentrations of bexagliflozin by Treatment and 
Timepoint will be provided. A listing of plasma concentrations by SubjectID, Treatment 
Period and Timepoint will also be provided. 
6.8 
Pharmacodynamic Assessment 
Urinary glucose excretion will be determined as the pharmacodynamic (PD) parameter at 
baseline (day 0 and day 7), and up to 48 h postdose (days 1-3 and 8-10). The effect of high-
fat meal will be evaluated by comparing the mean cumulative urinary glucose excretion 
(UGE) between subjects under fasted and fed conditions. Potential effects on urinary 
creatinine, uric acid, sodium, potassium, and calcium will also be analyzed. 
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. 
 
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding, for example), symptom, or disease temporally associated with the use of a 
medicinal product, whether or not considered related to the medicinal product. 
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; it 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, or 
• 
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 study drug. 
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 FPG (fasting plasma glucose) value < 70 mg/dL and 
documented as described in Section 6.9.4.4. 
Any increase in liver function tests (AST, aspartate aminotransferase (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 not iced, 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. 
 
Study Drug 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 study drug and the AE when 
the event responds to withdrawal of the study drug (dechallenge), and recurs with rechallenge 
by administration of the study drug. 
Probable: There is a reasonable causal relationship between the study drug and the AE. The 
event responds to dechallenge. Rechallenge is not required. 
Possible: There is a reasonable causal relationship between the study drug and the AE. 
Dechallenge is lacking or unclear. 
Not Likely: There is a temporal relationship to study drug administration, but there is not a 
reasonable causal relationship between the study drug and the event. 
Unrelated: There is not a temporal or causal relationship to study-drug administration. 
6.9.1 
Collecting and Reporting Adverse Events 
The investigator will periodically assess subjects for the occurrence of adverse events. To 
avoid bias in collecting information about adverse events, the investigator 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 must report any serious adverse event (SAE), by telephone, email, or fax, to 
Theracos or its representative immediately after the investigator 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 study drug (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 immediately if 
they suspect they might be pregnant (e.g., missed or late menstrual cycle). 
If a subject or investigator 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 must notify the Medical Monitor within 3 working days of the receipt of 
information that any female subject who has become pregnant. This reporting requirement 
will continue until 4 weeks after the last investigational product exposure. 
The investigator 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.

Page 30 of 48 
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 
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 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 study drug, 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 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 should continue 
to report any significant follow-up information to the Sponsor until the event has been 
resolved. This study requires that subjects be actively monitored for SAEs for at least 14 days 
after discharge from the study. 
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. 
Study drug should be permanently discontinued if any of the following criteria is met: 
• 
ALT or AST > 8xULN; 
• 
ALT or AST > 3xULN and (TBL > 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 person with diabetes reports 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). 
 
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 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. 
Concomitant medications will be coded using the World Health Organization Drug 
Dictionary (WHO-DD). A table of concomitant medications based on the anatomic 
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 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 
study drug 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 THR-1442-C-481 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. 
6.12 Appropriateness of Measurements 
PK and safety parameters in this protocol are standard assessments and are widely used and 
generally recognized as reliable, accurate, and relevant measurements. 
Determination of urinary glucose is a non-invasive and quantitative method that allows 
immediate assessment of the pharmacodynamic effects of an SGLT2 inhibitor.  The excreted 
glucose is dose dependent, saturable, and correlates with lowering of fasting plasma glucose 
and of hemoglobin A1c based on data from bexagliflozin studies and other SGLT2 inhibitors.

PLANNED STATISTICAL METHODS 
9.1 
General Considerations 
The statistical evaluation of PK 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 for Windows® 
(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 food-
drug interactions, and to provide safety and tolerability data on bexagliflozin when 
administered with food (Food and Drug Administration 2002). 
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. 
9.4 
Demographics and Baseline Characteristics 
Baseline characteristics including demographics, physical examination, ECG parameters, and 
safety laboratory values will be summarized for all subjects in the Safety and the PK 
Populations. Descriptive statistics will be performed. 
9.5 
Statistical Analysis of Pharmacokinetic Variables 
To assess the effect of a high-fat meal on the PK of bexagliflozin, an 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 fed: 
fasted ratio of the least squares (LS) geometric means of PK parameters (Cmax, AUC0-t and 
AUC0-∞), with 80-125% defined as the lack of interaction boundaries.

Page 39 of 48 
Descriptive statistics for the PK parameters Cmax, Tmax, AUC0-∞ , AUC0-t , 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 SubjectID and Treatment Period will 
be provided.  
Descriptive statistics on the PD parameters will be also performed. The effect of high-fat 
meal on the cumulative UGE between subjects under fasted and fed conditions will be 
compared.   
9.6 
Safety Analysis 
Safety data will 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. 
9.6.1 
Adverse Events 
Adverse events will be mapped to preferred term and body system using the Medical 
Dictionary for Regulatory Activities (MedDRA). The number and percentage of subjects 
reporting adverse events will be determined by relationship to treatment and by severity of 
the event. Drug-related adverse events will be considered those to be possibly related to 
bexagliflozin administration. 
Adverse event listings will be provided for the following subsets: 
• 
all treatment emergent AEs (TEAEs). 
• 
all TEAEs at least possibly related to bexagliflozin. 
• 
serious TEAEs (if any). 
• 
TEAEs leading to study discontinuation (if any). 
 
AEs are dosing emergent if they occur on or after bexagliflozin administration. TEAEs will 
be considered at least possibly related to bexagliflozin 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.
