Study Design:  
THR-1442-C-450 is a phase 3, multi-center, randomized, double-blind, placebo-controlled, 
parallel-group study to evaluate the efficacy and safety of once daily oral administration of 
bexagliflozin tablets, 20 mg versus placebo, in subjects with T2DM who are treatment-naïve 
or previously treated with one oral hypoglycemic agent (OHA). 
The study will enroll male or female subjects with T2DM. If treatment naïve, they must have 
an HbA1c at the screening visit of between 7% and 10.5%. Alternatively, prospective 
subjects may be eligible if at the time of the screening visit they are being treated with one 
OHA, have an HbA1c of between 6.5% and 10.0% and are willing to complete a 6-week 
washout. Individuals taking thiazolidinediones are not eligible for the study. A candidate will 
be considered treatment-naïve if he or she has received no more than 14 days of prescription 
medication for diabetes in the 12 weeks prior to screening.  
All eligible subjects will start a 2 week placebo run-in period.  Subjects who miss no more 
than one dose of the run-in medication, have fasting blood glucose values ≥ 250 mg/dL on no 
more than two consecutive days, and who, at the baseline visit (Visit V5), have an HbA1c 
level between 7 and 10.5% and a fasting glucose level < 250 mg/dL will be eligible for 
randomization. 
Approximately 210 subjects will be randomly assigned to receive oral bexagliflozin tablets, 
20 mg or placebo, in a 2:1 ratio once daily for 24 weeks in an out-patient setting.  Subjects 
with uncontrolled hyperglycemia based on blood glucose levels may receive additional 
approved anti-diabetic medications.  Treatment group assignment at the start of the treatment 
period will be stratified by baseline (Visit V5) HbA1c level (7.0 to 8.5% or 8.6 to 10.5%) and 
background anti-diabetes treatment status (treatment naïve or not).  
Each subject will be contacted by telephone at week 2 (Visit V7) for safety monitoring and 
will be instructed to return to the clinic at weeks 6, 12, 18, and 24 (Visits V8, V9, V10, V11, 
respectively) for efficacy assessment and safety monitoring. Subjects will return to the clinic 
for a follow-up visit at week 26 or two weeks after the last dose of investigational product if 
the subject terminates prior to week 24 (Visit V12). 
Study Population and main eligibility criteria: 
Approximately 210 subjects are planned for this study. The study will enroll: 
1. Male or female adult subjects ≥ 18 years of age at screening.  
2. Subjects with T2DM who are treatment naïve or receiving one OHA in combination with 
diet and exercise. Subjects taking thiazolidinediones are not eligible. 
3. Subjects with HbA1c levels at screening (Visit V1) between 7.0% and 10.5% (inclusive) 
if treatment-naïve or with HbA1c levels between 6.5 and 10.0% (inclusive) if on one 
OHA 
4. Subjects with a body mass index (BMI) ≤ 45 kg/m2 
5. Subjects with a fasting plasma glucose < 250 mg/dL (13.9 mmol/L) at baseline (Visit V5) 
Test Product, Dose, and Mode of Administration:  
Bexagliflozin tablets, 20 mg or placebo, administered orally once daily

Duration of Treatment:  
24 weeks 
Efficacy Assessments:  
The primary efficacy measure will be the change in HbA1c from baseline to week 24. 
The key secondary measures will be the changes from baseline to week 24 of systolic blood 
pressure and body weight. The exploratory secondary measures will be the change from 
baseline of the fasting plasma glucose concentration over time, the change from baseline of 
HbA1c over time, and the proportion of subjects who achieve an HbA1c < 7% over time. 
Safety Assessments:  
The safety of bexagliflozin will be assessed over the 24-week treatment phase. Adverse 
events (AEs) of special interest include genital and urinary tract infections, diuretic effects, 
hepatotoxicity, MACE, hypoglycemia, fractures, malignancy, hypersensitivity reactions, 
hypotensive episodes, acid-base disorders, renal failure events, and amputations.  
Statistical Methods:  
Data summaries will report descriptive statistics (number of subjects [n], mean, standard 
deviation [SD], Q1, median, Q3, minimum, and maximum for continuous variables, and 
frequency and percentage for categorical and ordinal variables.  If there are missing values, 
the number missing will be presented, but without a percentage.  All data collected will be 
included in by-subject data listings.  
The primary efficacy hypothesis is that bexagliflozin reduces HbA1c after 24 weeks of 
treatment when compared to placebo. The analysis of the change in HbA1c at week 24 will 
be based on ITT Analysis Set using all observed data and a mixed model repeated measures 
(MMRM) approach that will include terms for treatment, visit, treatment-by-visit interaction 
and randomization stratification factors as fixed effects and the baseline HbA1c value as a 
fixed effect covariate. Least squares mean treatment differences between the bexagliflozin 
group and the placebo group at week 24 will be estimated from the model with the 
corresponding p-values and their two-sided 95% CI presented. An unstructured covariance 
will be used to model the within-subject correlation. If the model with the unstructured 
covariance structure does not converge, an autoregressive(1) covariance structure will be 
used. HbA1c values obtained after the start of rescue medication will not be excluded from 
the analysis. 
The MMRM model is one approach to obtain treatment effect estimates in the presence of 
missing data. As sensitivity analyses for missing data, the following will be performed on the 
ITT analysis set: 
1. Missing HbA1c data will be imputed via multiple imputations, following which the 
MMRM will be repeated on the complete datasets with results combined across complete 
datasets using standard MI techniques; HbA1c values collected after the start of rescue 
medication will not be excluded from the analysis. 
2. HbA1c values collected after the start of rescue medication will be excluded (considered 
missing), and the MMRM analyses will be re-performed. 
3. A last observation carried forward (LOCF) method will then be used to impute the 
missing observations prior to carrying out the MMRM model. 
The effect of bexagliflozin on body weight and systolic blood pressure will be tested as key

secondary efficacy endpoints and will be analyzed in a hierarchical testing strategy only if 
the primary objective is met. ANCOVA models will also be used for the continuous 
secondary endpoints analyses.  Longitudinal data will be evaluated through repeated 
measures tests. A hierarchical testing in the following order will be applied to preserve 
experiment-wide alpha at 0.05 in the case each successive determination meets significance: 
1. To test the hypothesis that bexagliflozin reduces systolic blood pressure from baseline to 
week 24 compared with placebo 
2. To test the hypothesis that bexagliflozin reduces body weight from baseline to week 24 
compared with placebo in subjects with a BMI ≥ 25 kg/m2 
The effect of bexagliflozin on fasting plasma glucose, on the proportion of subjects reaching 
< 7.0% HbA1c, and on the change in HbA1c over time will be analyzed as exploratory 
efficacy endpoints and will not be adjusted for multiplicity.  
Safety data will include AEs, physical exam results, vital signs, ECG results, and clinical lab 
results including serum chemistry, hematology, serum lipids, glycemic control parameters 
and urinalysis. The general safety of bexagliflozin in subjects with type 2 diabetes mellitus 
will be analyzed as well as the contribution of bexagliflozin to AEs of special interest. 
For the primary efficacy endpoint, a power calculation was performed for significance 
calculated by a two group t-test with a two-sided α of 0.05. Taking the standard deviation for 
the change in HbA1c to be 1%, a sample size of 128 in the bexagliflozin group and 64 in the 
placebo group is predicted to have 90% power to detect a difference between groups of 0.5% 
in mean HbA1c change. To account for an estimated drop-out rate of approximately 10%, a 
study design was adopted in which 140 subjects are planned to be randomized to the 
bexagliflozin group and 70 subjects to the placebo group.  Statistical analyses and summaries 
will be performed using SAS® software (SAS Institute, Cary, NC).

INTRODUCTION 
T2DM is the predominant form of diabetes and accounts for at least 90% of all diabetes 
cases, which is characterized by insulin resistance and relative or absolute insulin 
insufficiency. Despite the availability of several classes of therapeutics, the number of people 
with diabetes is projected to increase by nearly 55% to over 642 million adults by 2040 (IDF 
2015).  Among the debilitating consequences of T2DM are peripheral neuropathy, 
retinopathy, renal failure, peripheral ischemia and exacerbations of cardiovascular disease, 
which result in blindness, amputation, dialysis and death. 
T2DM is a disease strongly linked to increased body fat mass in the majority of cases 
(Schwartz, Fabricatore et al. 2012). Weight loss has been shown to improve glycemic control 
and to reduce the severity of diabetes-associated comorbidities, supporting the view that anti-
diabetic agents that promote weight loss may be particularly beneficial for the treatment of 
the disease (Look, Wing et al. 2013; Scheen and Van Gaal 2014).Several classes of agents 
are available for treating T2DM, including insulin and its secretagogues, PPARγ agonists, 
biguanides, alpha glucosidase inhibitors, glucagon-like peptide 1 (GLP-1) receptor agonists, 
sulfonylureas, meglitinides and dipeptidyl peptidase 4 (DPP4) inhibitors.  However, the 
increasing incidence of T2DM has led to an increasing recognition that additional 
therapeutics are needed to provide safe and effective reductions of elevated plasma glucose 
levels.  New agents to treat T2DM would ideally treat hyperglycemia and avoid common 
side effects of currently available agents, such as weight gain, gastrointestinal disturbance, 
and hypoglycemia. 
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 (van den Heuvel, Assink et al. 2002; 
Santer, Kinner et al. 2003).  The excretion of glucose in the urine of diabetic subjects in 
amounts comparable to or greater than that seen in individuals harboring loss of functions 
mutations in SLC5A2 has the potential to improve fasting and postprandial hyperglycemia 
without increasing insulin secretion, causing weight gain, or inducing hypoglycemia. Several 
SGLT2 inhibitors have demonstrated these clinical benefits as well as sustained weight loss 
when used as a mono-therapy or in combination with other oral anti-diabetic medications 
including insulin (Nauck 2014; Seufert 2015). 
1.1 
Bexagliflozin for the treatment of type 2 diabetes mellitus 
Bexagliflozin is a candidate oral antidiabetic agent that is a potent and highly specific 
inhibitor of SGLT2. It was identified following a synthetic program aimed at creating 
molecules with high selectivity and potency for SGLT2 (Zhang, Welihinda et al. 2011). 
Bexagliflozin has been shown to cause dose-dependent increases in urinary glucose excretion 
(UGE) in humans, rats, dogs and monkeys and to reduce HbA1c in animal models of T2DM 
as well as in diabetic subjects. The safety and efficacy of bexagliflozin capsules, 20 mg, were 
evaluated in a 96-week study that measured reduction in hemoglobin A1c as the primary 
endpoint. Adverse event incidences, particularly for urinary tract infection (UTI) and genital 
mycotic infection (GMI), were similar between placebo and active agent cohorts. Details of

STUDY OBJECTIVES 
2.1 
Primary Efficacy Objective 
The primary efficacy objective of this trial is to determine the placebo-adjusted treatment 
effect of bexagliflozin tablets, 20 mg on the change in HbA1c from baseline to week 24 in 
subjects with T2DM and inadequate glycemic control. 
2.2 
Secondary Efficacy Objectives 
The key secondary efficacy objectives of this study are: 
• To compare the effect of bexagliflozin to effect of placebo on the change in systolic 
blood pressure (SBP) from baseline to week 24  
• To compare the effect of bexagliflozin to the effect of placebo on the change in body 
weight from baseline to week 24 in subjects with a BMI ≥ 25 kg/m2  
 
The other exploratory secondary efficacy objectives are: 
• To compare the effect of bexagliflozin to the effect of placebo on the proportion of 
subjects with HbA1c of < 7%  
• To compare the effect of bexagliflozin to the effect of placebo on change in HbA1c over 
time  
• To compare the effect of bexagliflozin to the effect of placebo on FPG over time 
 
2.3 
Safety Objectives 
• To compare the safety of bexagliflozin to the safety of placebo in subjects with T2DM 
• To compare the effect of bexagliflozin to the effect of placebo on the incidence of 
adverse events (AE) of special interest. AEs of special interest include either upper or 
lower UTIs, GMI, hepatic toxicity, hypoglycemia, falls and fractures, cardiovascular 
events, malignancies, hypersensitivity reactions, hypotensive episodes, acid-base 
disorders, renal failure events and amputations. 
• To contribute major adverse cardiovascular events (MACE+) to an eventual meta-
analysis that is intended to exclude a hazard ratio of 1.8 or greater for subjects exposed to 
bexagliflozin compared to subjects exposed to placebo. MACE+ is defined as 
cardiovascular death, non-fatal myocardial infarction (MI), non-fatal stroke, or 
hospitalization for unstable angina.

INVESTIGATIONAL PLAN 
3.1 
Overall Study Design and Plan 
THR-1442-C-450 is a multi-center, randomized, double-blind, placebo-controlled, parallel-
group study. It is designed to compare the efficacy and safety of once daily oral 
administration of bexagliflozin tablets, 20 mg to bexagliflozin tablets, placebo in treatment-
naïve type 2 diabetic subjects or subjects previously treated with no more than one oral 
hypoglycemic agent (OHA). 
The study will enroll both male and female subjects with T2DM. If treatment naïve, they 
must have an HbA1c at the screening visit of between 7% and 10.5%. Alternatively, 
prospective subjects may be eligible if at the time of the screening visit they are being treated 
with one OHA, have an HbA1c of between 6.5% and 10.0% and are willing to complete a 6-
week washout. Individuals taking thiazolidinediones are not eligible for the study. A 
candidate will be considered treatment-naïve if he or she has received no more than 14 days 
of prescription medication for diabetes in the 12 weeks prior to screening.  
All eligible subjects will start a 2 week placebo run-in period.  Subjects who miss no more 
than one dose of the run-in medication, have fasting blood glucose values ≥ 250 mg/dL on no 
more than two consecutive days, and who, at the baseline visit (Visit V5), have an HbA1c 
level between 7 and 10.5% and a fasting glucose level < 250 mg/dL will be eligible for 
randomization. 
Approximately 210 subjects will be randomly assigned to receive oral bexagliflozin tablets, 
20 mg or placebo, in a 2:1 ratio once daily for 24 weeks in an out-patient setting.  Subjects 
with uncontrolled hyperglycemia based on blood glucose levels may receive additional 
approved anti-diabetic medications.  Treatment group assignment at the start of the treatment 
period will be stratified by HbA1c level at the start of the run-in period (7.0 to 8.5% or 8.6 to 
10.5%) and background anti-diabetes treatment status (treatment naïve or not).  
Each subject will be contacted by telephone at week 2 (Visit V7) for safety monitoring and 
will be instructed to return to the clinic at weeks 6, 12, 18, and 24 (Visits V8, V9, V10, V11) 
for efficacy assessment and safety monitoring. Subjects will return to the clinic for a follow-
up visit at week 26 or two weeks after the last dose of investigational product if the subject 
terminates prior to week 24 (Visit V12). 
3.2 
Research Methods and Procedures 
3.2.1 
Wash-out and Run-in Period 
Eligible subjects who are not treatment naïve will discontinue their current OHA and enter a 
6 week wash-out period. At the start of the wash-out (Visit V2), each subject will be 
provided with diet and exercise counseling, a glucometer, a glycemic control diary in which 
to record symptoms related to any hyper- or hypoglycemic events, and instructions as to 
when to call the clinic for hyperglycemia (see Glycemic Control Monitoring, below). Two 
weeks after the start of the wash-out period (Visit V3), each subject will participate in a 

Bexagliflozin Tablets

phone interview visit with study staff for self-monitored blood glucose (SMBG) data review 
and general safety evaluation. Subjects who remain eligible at the end of the wash-out period 
will proceed to a 2-week placebo run-in period. Subjects who have fasting blood glucose 
values ≥ 250 mg/dl on two consecutive days during the washout will not be eligible for the 
run-in period. 
Eligible subjects who are treatment naïve will not require a wash-out period and will proceed 
to the run-in period. These subjects will be provided with diet and exercise counseling, a 
glucometer, and a glycemic control diary in which to record symptoms related to any hyper- 
or hypoglycemic events at the start of the placebo run-in period (Visit V4). 
Treatment naïve subjects and subjects on background anti-diabetic therapy who complete the 
6-week wash-out will enter the 2-week single-blind placebo run-in period. At the start of the 
run-in period, each subject will be provided with placebo drug, dosing instructions, and 
instructions as to when to call the clinic should hyperglycemia develop (see Glycemic 
Control Monitoring, below). During the run-in, placebo will be taken daily in the morning 
with 250 mL of water prior to eating or drinking. 
Subjects will not be eligible for randomization if, during the run-in period, they: 1) have 
fasting blood glucose values ≥ 250 mg/dL on two consecutive days, 2) miss more than 1 dose 
of placebo, 3) are deemed inappropriate for the study by the investigator or 4) at the base line 
visit (Visit V5), have HbA1c value < 7.0% or >10.5%. At the baseline visit, subjects must 
have a fasting glucose level < 250 mg/dL (13.9 mmol/L) to be eligible for randomization.   
Approximately 210 subjects will be randomly assigned in 2:1 ratio to receive bexagliflozin 
tablets, 20 mg or bexagliflozin tablets, placebo once daily for 24 weeks.  Randomization at 
the start of the treatment period will be stratified by HbA1c level at the final assessment prior 
to randomization (Visit V5) (7.0 to 8.5% or 8.6 to 10.5%) and by background anti-diabetes 
treatment status (treatment naïve or not). 
3.2.2 
Treatment Period 
The treatment period will start at randomization (Visit V6) and end after 24 weeks. At the 
start of the treatment period, each subject will be provided investigational product, dosing 
instructions, and glycemic control diary in which to record symptoms related to any hyper- or 
hypoglycemic events as well as information related to the occurrence of such events. 
Subjects with uncontrolled hyperglycemia based on blood glucose levels may receive 
additional approved anti-diabetic rescue medications (see Prescription of Rescue Medication 
below).  Bexagliflozin tablets will be orally administered in the morning with 250 mL of 
water prior to eating or drinking. 
Each subject will participate in a telephone consultation at week 2 (Visit V7) for safety 
monitoring. Each subject will be instructed to return to the clinic at weeks 6, 12, 18, and 24 
(Visits V8, V9, V10, V11, respectively) for efficacy assessment and safety monitoring, 
including review of adverse events and concomitant medication, evaluation of vital signs, 
electrocardiogram (ECG), and a physical examination, and for a blood draw and urine

collection for clinical laboratory. On the day of the clinic visit, a fasting time of 
approximately 10 hours must be confirmed prior to blood draw. 
To minimize the effect of missing values on data analysis and study outcome interpretation, 
considerable effort will be made to prevent missing data, to train site staff to encourage study 
subject participation and to remain vigilant to signs of non-compliance, to remain in contact 
with study subjects who have withdrawn from the study to collect as nearly complete a data 
set as is feasible, and to determine all reasons for missing data. 
Subjects will return to the clinic for a follow-up exit visit at week 26 (Visit V12) or two 
weeks after the last dose of investigational product if the subject terminates prior to week 24. 
Following the exit visit, subjects will be advised to see their primary physician and resume 
treatment to control their diabetes. The duration of participation for each subject can be up to 
37 weeks depending on prior treatment status. 
3.2.3 
Glycemic Control Monitoring 
3.2.3.1 
Washout Period 
During the wash-out period, subjects will be instructed to determine SMBG daily after an 
overnight fast of approximately 10 hour duration. If the fasting blood glucose is ≥ 250 mg/dL 
(13.9 mmol/L) during the wash-out period, the subject should contact the clinic within 24 
hours, and the investigator will determine whether the participant should attempt to improve 
diet and exercise to maintain glycemic control or if the participant must withdraw from the 
study and initiate a more intense pharmacological regimen for glucose control. If fasting 
blood glucose is ≥ 250 mg/dL (13.9 mmol/dL) on two consecutive days during the washout, 
the subject should contact the clinic staff and will be excluded from participation in the study 
Subjects with SMBG readings ≥ 250 mg/dL (13.9 mmol/L) and severe clinical signs or 
symptoms of hyperglycemia during the wash-out period, including weight loss, blurred 
vision, increased thirst, increased urination, or fatigue will be excluded from participation in 
the study. 
3.2.3.2 
Placebo Run-in Period 
During the placebo run-in period, subjects will be instructed to determine SMBG daily after 
an overnight fast of approximately 10 hour duration. If the fasting blood glucose is ≥ 250 
mg/dL (13.9 mmol/L) during the run-in period, the subject should contact the clinic within 24 
hours, and the investigator will determine whether the participant should attempt to improve 
diet and exercise to maintain glycemic control or if the participant must withdraw from the 
study and initiate a more intense pharmacological regimen for glucose control. If fasting 
blood glucose is ≥ 250 mg/dL (13.9 mmol/dL) on two consecutive days during the run-in, the 
subject should contact the clinic staff and will be excluded from participation in the study.  
The investigator or designee will review the glucometer data and glycemic control diary at 
the end of the run-in period. Subjects with fasting blood glucose ≥ 250 mg/dL (13.9 
mmol/dL) on two consecutive days during the run-in period will excluded from participation. 
In addition, subjects with SMBG readings  ≥ 250 mg/dl (13.9 mmol/L) and clinical signs or

symptoms of severe hyperglycemia, including weight loss, blurred vision, increased thirst, 
increased urination, or fatigue will be excluded from participation in the study. 
3.2.3.3 
Main Treatment  
During the 24-week treatment period, subjects will be advised to continue daily fasting 
SMBG measurements. Subjects should contact the clinic if any fasting SMBG is ≥ 270 
mg/dL (15 mmol/L) from week 1 to week 6, ≥ 240 mg/dL (13.3 mmol/L) after week 6 to 
week 12, or ≥ 200 mg/dL (11.1 mmol/L) after week 12 to week 24. Blood glucose values 
collected via SMBG will be evaluated at study visits by the investigator. In addition, 
hyperglycemia will be monitored by fasting plasma glucose (FPG) measurement at each 
study visit. 
If hyperglycemia is identified through SMBG or FPG measurements, the investigator will 
first determine whether the subject had fasted for approximately 10 hour prior to the blood 
draw to ensure that the FPG value is truly a fasting sample. If proper fasting had not 
occurred, the subject should be asked to return for a repeat blood test within a week.  
During the treatment period, hyperglycemia should be managed first with diet and exercise 
counseling and should be managed with changes in the medical therapy only if the 
investigator feels it is necessary for the well-being of the subject (see below, Prescription of 
Rescue Medication). After the treatment period, changes to the medical therapy for 
hyperglycemia should occur at the discretion of the investigator based on SMBG, FPG, and 
HbA1c information using local standards of care for subjects with T2DM.  
If a concomitant medication for hyperglycemia is to be prescribed, a blood sample must be 
drawn prior to the administration of the rescue medication so that a final HbA1c value can be 
determined. 
3.2.3.4 
Prescription of Rescue Medication 
Rescue medication for hyperglycemia should be prescribed by the investigator at any time it 
is deemed necessary for the well-being of the subject. During the 24 week treatment period, a 
review of diet and exercise counseling is suggested prior to prescription of rescue medication 
in the absence of specific medical indications for rescue medication. Rescue medication is 
suggested during the treatment period if, after a review of diet and exercise counseling:  
1. more than 3 consecutive, daily, fasting SMBG measures are ≥ 270 mg/dL (15 mmol/L) 
from week 1 to week 6, ≥ 240 mg/dL (13.3 mmol/L) from week 6 to week 12, or 
≥ 200 mg/dL (11.1 mmol/L) from week 12 to week 24 
2. persistent clinical signs or symptoms of hyperglycemia are present (e.g. weight loss, 
blurred vision, increased thirst, or increased urination, or fatigue) 
 
The investigator may provide rescue treatment with any approved medication for diabetes 
that is not otherwise contraindicated, with the exception of an SGLT2 inhibitor.

Subjects who receive rescue medication due to poor glycemic control will continue to receive 
investigational product and standard of care per investigator decision, according to current 
treatment guidelines, during the treatment period. Following the exit visit, subjects will be 
advised to see their primary care physician and resume standard treatment to control their 
diabetes. 
If hypoglycemia occurs in any subject prescribed rescue medication for hyperglycemia 
during the study, the total daily dose of the rescue medication should be reduced 50% or 
more at the discretion of the investigator. 
3.2.4 
OTHER SAFETY MONITORING ACTIVITIES  
The safety monitoring activities will include assessment of vital signs, physical 
examinations, urinalysis, blood chemistry, hematology, AEs, and concomitant medication 
(ConMed) use.  The occurrence of blood, liver, or skin disorders will be monitored through 
laboratory testing and evaluation of adverse event documentation.  Adverse events of special 
interest as defined in the statistical analysis plan will include any clinical signs and symptoms 
that indicate either upper or lower UTI, GMI, hepatic toxicity, hypoglycemia, falls and 
fractures, MACE+, malignancies, hypersensitivity reactions, hypotension episodes, acid-base 
disorders, and renal failure events.  All such events must be appropriately documented within 
source documentation. 
DATA AND SAFETY MONITORING BOARD (DSMB)  
An independent DSMB will review unblinded safety information during the bexagliflozin 
development program. The safety review activities and potential risk benefit assessments 
utilized by the DSMB are defined in its charter. 
MAJOR ADVERSE CARDIOVASCULAR EVENT ADJUDICATION 
An independent cardiovascular endpoint committee (CEC) has been established to review, 
under blind, all potential cardiovascular events occurring during the study.  The events of 
interest include cardiovascular mortality, myocardial infarction, stroke, hospitalization for 
acute coronary syndromes, urgent revascularization procedures, and other possible serious 
cardiovascular events.  The adjudicated events will be documented and archived to allow a 
meta-analysis to be performed at a later time.  Events occurring in this study will be 
classified as belonging to MACE+ or not. MACE+ is defined as cardiovascular death, non-
fatal MI, non-fatal stroke, or hospitalization for unstable angina. No separate cardiovascular 
risk assessment will be performed based on events in the study population of the current 
protocol. 
3.3 
Rationale for Study Design and Dose Selection 
3.3.1 
Rational for Study Design and Control Group 
This study is designed to evaluate the efficacy and safety of bexagliflozin for the treatment of 
subjects with T2DM. A randomized, double-blind study design reduces bias and confounding 
by unmeasured factors and is the most suitable design to evaluate a new agent as a

monotherapy in diabetic subjects. Under the close monitoring detailed in this protocol, 
placebo is the appropriate control for the subject population studied during the treatment 
period (24 weeks). In order to reduce the possibility that the change in HbA1c level from 
baseline to 24 weeks is determined by medications taken prior to the study, an up to 8 week 
washout and run-in period will be implemented prior to randomization of subjects on prior 
OHAs.  All subjects will receive a placebo in the 2 weeks immediately prior to 
randomization to allow compliance with the dosing regimen to be monitored.  Subjects with 
FPG levels ≥ 250 mg/dL at the visit prior to randomization (Visit V5) will be excluded as a 
safety measure. Diet and exercise counseling will be provided to all participating subjects to 
reduce risks of worsening diabetic conditions. A monitoring plan based on the measurements 
of SMBG, FPG, and HbA1c, as well as criteria to initiate rescue medications, is included in 
the protocol to prevent prolonged hyperglycemia.  
Results from studies of individuals with genetic mutations in the gene encoding SGLT2, of 
subjects that have been treated with other SGLT2 inhibitors, and of previous clinical studies 
in healthy or diabetic subjects treated with bexagliflozin, indicate that the risk of 
hypoglycemia caused by inhibition of SGLT2 activity is likely to be minimal.  
Reduction in HbA1c is considered a well validated surrogate for the long-term microvascular 
complications of diabetes mellitus. HbA1c levels reflect mean glycemic control over 2 to 3 
months, and therefore the primary endpoint of HbA1c measurement at 24 weeks will assess 
the effect of bexagliflozin compared to placebo over a sustained period.  
3.3.2 
 Rational for Dose Selection 
Bexagliflozin produces a dose-dependent, saturable increase in UGE in healthy volunteers 
and diabetic subjects. Near-maximal UGE is produced by 20 mg of bexagliflozin, whether 
delivered as an immediate release or an extended release formulation. Population 
pharmacodynamic modeling has indicated that bexagliflozin doses of 20 mg result in 90% of 
the maximal UGE. In a long term treatment study, daily administration of 20 mg 
bexagliflozin in an immediate release formulation was found to reduce HbA1c by 0.79% 
compared to placebo at week 24. The treatment benefit was observed to improve to 1.02% at 
week 96. FPG reduction, weight loss, and decreased systolic and diastolic blood pressure 
were also observed following 96 weeks of treatment. In addition, AEs, particularly those 
involving UTI and GMI, were found to be similar between placebo and active agent cohorts. 
To evaluate the safety and efficacy of bexagliflozin for the treatment of subjects with T2DM, 
bexagliflozin tablets, 20 mg will be administered in this trial. 
3.4 
Study Duration and Dates 
Potential subjects will be screened within 3 weeks of the start of wash-out or run-in period. 
Eligible subjects who are taking a background OHA and sign the informed consent will start 
a 6-week wash-out period, followed by a 2-week single-blind placebo run-in period. Eligible 
subjects who are treatment naïve and sign the informed consent form will immediately start 
the 2-week single blind placebo run-in period. Subjects who remain eligible at the end of the 
run-in period will receive 24 weeks of treatment. All subjects who are randomized will be 
followed for 2 weeks after the last dose of investigational product.

STUDY TREATMENT(S) 
5.1 
Description of Treatment(s) 
5.1.1 
Investigational Product 
Bexagliflozin tablets, 20 mg or placebo, 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 hour in simulated gastric fluid in vitro.  
The following investigational products will be used for oral administration: 
• Bexagliflozin tablets, 20 mg: tablets containing 20 mg of bexagliflozin 
• Bexagliflozin tablets, placebo: tablets containing no bexagliflozin 
 
5.2 
Treatments Administered 
Bexagliflozin tablets, 20 mg or placebo, should be taken with 250 mL of water in the 
morning prior to eating or drinking. 
5.3 
Selection and Timing of Dose for Each Subject 
Dosing with bexagliflozin tablets, 20 mg or placebo, will be based on randomized 
assignment.  All study subjects will be instructed to self-administer tablets once daily with 
250 mL of water in the morning prior to eating or drinking.  There will be no change of dose 
during the 24-week treatment period.  
On the day of each scheduled clinic visit, subjects must fast for approximately 10 hours prior 
to the collection of blood samples. On the day of each scheduled clinic visit, bexagliflozin 
tablets should be taken with water in the morning prior to eating or drinking (as above) and 
prior to the collection of blood samples. During the fasting period, only water will be 
permitted. 
5.4 
Method of Assigning Subjects to Treatment Groups 
Eligible subjects who complete the run-in period and meet all study inclusion/exclusion 
requirements will be randomized in a 2:1 ratio to receive once daily bexagliflozin tablets, 20 
mg or bexagliflozin tablets, placebo during the 24-week treatment period. Subjects will be 
assigned to treatment groups in sequential order as they qualify for the study, using a 
centrally located and managed Interactive Web Response System (IWRS). Randomization 
will be stratified according to HbA1c measured at the last assessment prior to randomization 
(Visit V5) (HbA1c at 7.0 to 8.5% or 8.6 to 10.5%) and background anti-diabetic treatment 
status (treatment-naïve or on treatment).  
The study will be conducted at multiple investigative sites and will likely involve a variable 
numbers of subjects at each site. Enrollment will be on a competitive basis but each site will

be capped at 21 randomized subjects. However, when a site reaches 21 randomized subjects, 
if a potential subject at that site is in washout or run in already and wishes to continue with 
the study, the subject will be allowed to continue and, if eligible, to be randomized. Subject 
randomization will be deactivated for all sites when the planned number of subjects has been 
enrolled.  However, if a potential subject is in washout or run in already and wishes to 
continue with the study, the subject will be allowed to continue and, if eligible, to be 
randomized. 
5.5 
Blinding 
This is a double-blind placebo-controlled study.  The sponsor, investigators, study 
coordinators, pharmacists, study subjects, and the CEC members will be blinded to the study 
medication.  Upon randomization, each subject will receive a subject randomization number 
and a drug kit assigned to the subject.  To maintain blinding of the individual treatment 
assignments, central laboratory glucose urinalysis data will not be made available to any 
study personnel or subjects. 
If knowledge of the test substance is needed to manage the subject’s condition, the 
investigator will contact the IWRS to obtain the treatment assignment.  If unblinding occurs 
for any reason, the time and reason for breaking the blind will be recorded in the case report 
form (CRF) and the sponsor must be notified within 24 hours.  
A designated statistician who is not involved with the study operation will hold the treatment 
codes.  The unblinded treatment information can be provided to the DSMB to facilitate the 
evaluation of any clinically important increase in the rate of a serious suspected adverse 
reaction or to the designated safety contact when the treatment information is required to 
determine if an expedited safety report must be submitted to regulatory agencies.   
The treatment assignment will continue to be withheld from the CEC members at the 
conclusion of the study until all global investigational studies are completed and a meta-
analysis to assess cardiovascular risk is conducted. 
5.6 
 Concomitant Therapy 
Subjects will be allowed to take medications or medicinal supplements prescribed to manage 
non-diabetic medical conditions during the study. Any concurrent medication or supplement 
treatment of non-diabetic medical conditions should be continued at a stable dose and 
frequency for the entire study duration unless there is clinical reason to change the dose or 
frequency.  
During the run-in period, blood pressure medications can be altered to optimize blood 
pressure control at the discretion of the investigator, although adjustment of blood pressure 
medications during the first 12 weeks of the treatment period should be avoided unless it is 
medically necessary to do so. If it is medically necessary to alter blood pressure medications 
during the first 12 weeks of the treatment period, new diuretic medications should not be 
initiated and the dose and frequency of existing diuretic medications should not be altered.

Subjects who do not meet protocol-specified glycemic targets at specified time points during 
the study will review diet and exercise counseling and/or receive rescue medication at the 
discretion of the investigator during the study. Anti-diabetic therapies prescribed to subjects 
for the purpose of treating hyperglycemia will be considered rescue medications if they are 
continued for at least 2 weeks (see Prescribing Rescue Medication, above). A blood sample 
will be collected for the measurement of the last HbA1c value prior to administration of any 
rescue medications. The rescue medications must be recorded as concomitant medications in 
the CRF. 
To minimize the effect of missing values on data analysis and study outcome interpretation, 
considerable effort will be made to prevent missing data, to train site staff to encourage study 
subject participation and to remain vigilant to signs of non-compliance, to remain in contact 
with study subjects who have withdrawn from the study to collect as nearly complete a data 
set as is feasible, and to determine all reasons for missing data. 
Subjects may receive any medications for AEs that are necessary in the investigators’ 
judgment. Concomitant medications prescribed at the time of the run-in period and during the 
study are to be recorded in 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 through the treatment period and the follow up period.  
Any medication prescribed to a subject after enrollment and prior to randomization, 
including contraceptives, must be recorded in the CRF. 
5.7 
Restrictions 
5.7.1 
Prior Therapy 
All subjects will continue regimens for medical conditions other than diabetes during the 
study as indicated above.  No subject shall have been treated with an investigational drug 
within 30 days of screening or within a period equal to less than 7 half-lives of the 
investigational drug, whichever is longer. No subject shall have been treated with an SGLT2 
inhibitor within 3 months of screening. Subjects taking insulin or GLP-1 receptor agonists or 
members of the thiazolidinedione class of drugs are not eligible for this study. 
5.7.2 
Fluid and Food Intake  
During the study, subjects will be counseled to remain well hydrated at all times. In addition, 
subjects will receive counseling regarding an appropriate diet to achieve glycemic control 
based on standards of medical care in diabetes. The diet should be low in saturated fat, high 
in fiber, and low in simple carbohydrates and should contain appropriate caloric content to 
maintain weight.  Subjects will fast for approximately 10 hours prior to the scheduled blood 
sample draws. During fasting, only water will be permitted. 
5.7.3 
 Subject Activity Restrictions 
Throughout the study period, subjects are counseled and encouraged to engage in a level of 
physical activity that is appropriate for their physical condition. For those without specific

restrictions or limitations, at least 150 min/week of moderate activity is advised by the 
American Diabetes Association (ADA, 2013).  Alternatively, local guidelines may be 
followed. 
5.8 
Treatment Compliance 
Subjects will be provided with dosing instructions each time that study medication is 
dispensed.  Subjects will also be instructed to bring their medication with them at every visit.  
During the run-in period, subjects will be considered compliant in investigational product 
administration by missing no more than one dose of run-in medication. Subjects who are not 
compliant during the run-in period will be excluded from randomization. 
At each visit the study staff will review the SMBG control diary, glucometer data and 
medication use with the subject and record the drug consumption in the CRF. Reasons for 
non-adherence will also be recorded in the protocol deviation log if applicable. 
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. Bottles of 15 placebo tablets will be 
provided for the 2-week run-in portion of the study. All investigational product supplies will 
be prepared and labeled according to the requirements of local laws and regulations and will 
be kept in a secure storage facility at controlled room temperature, 15 to 30 °C (59 to 86°F).  
The pharmacist or designated site personnel will dispense the investigational products for 
each subject according to randomization assignment made in the Interactive Web Response 
System (IWRS). During the treatment period, subjects will be provided with an 
investigational product kit at randomization (Visit V6) and a new investigational product kit 
at 12 weeks (Visit V9). There will be no intra-subject dose escalation or back-titration. 
Subjects who require rescue medication due to hyperglycemia will receive standard care for 
T2DM in addition to the investigational product. 
There are two types of investigational product kits: 
RUN-IN KIT 
One run-in kit contains a bottle of 15 bexagliflozin tablets, placebo.  
The label attached to each run-in kit will contain the protocol number, product identification, 
lot number, subject number, storage condition, sponsor’s name and address, and the 
investigational drug caution statement. 
INVESTIGATIONAL PRODUCT KIT 
One investigational product kit contains a bottle of 90 bexagliflozin tablets, 20 mg or 
bexagliflozin tablets, placebo.

The label attached to each investigational product kit will contain the following information: 
the kit number, protocol number, product identification, blinded batch number, subject 
number, storage conditions, sponsor’s name and address, investigator’s name, and the 
investigational drug caution statement. 
5.10 Storage and Accountability 
Bexagliflozin tablets will be stored at controlled room temperatures of 15 °C to 30 °C (59 °F 
to 86 °F). The rescue medications will be stored in conditions specified in the manufacturers’ 
prescription information. The sponsor will notify the sites of the process for returning unused 
drug. 
5.11 Investigational Product Retention at Study Site 
The investigational products should be stored in a secure area with limited access.  The drug 
storage facility must comply with the medication storage instructions.  Bexagliflozin tablets 
should be stored at controlled room temperature until ready for dispensing to study subjects. 
The trial staff must record the amount of investigational product dispensed to each subject on 
the dosing record.  To ensure adequate recordkeeping, subjects must bring all investigational 
products to each visit.  The remaining tablets will be accounted for in the CRF and drug 
consumption forms.  The procedures for obtaining drug resupply will be provided by the 
sponsor.  At the completion of the trial, all unused drug must be returned to a sponsor-
designated depot after drug accounting is verified by Theracos 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 patient according to the regulatory and legal requirements of the 
participating country.  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 or designee 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 ICH guidelines.   
The informed consent document must be signed and dated; one copy will be given to the 
patient, 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 
Screening or Confirmation for I/E Criteria  
At the initial screening, the investigator should review the inclusion and exclusion criteria 
based on the information collected at the screening visit. He or she should evaluate any 
change to status affecting conformance to inclusion and exclusion criteria at subsequent visits 
prior to randomization.  At randomization, the investigator should confirm the run-in drug 
compliance. 
6.3 
Medical History  
The following information will be collected at the screening visit: 
6.3.1 
General Demographics and Characteristics  
1. Date of birth, age, sex, and race, and whether a female subject is of childbearing potential 
or not. 
2. Significant medical (including alcohol/illicit drug abuse within the last 2 years) and 
surgical history, including dates of diagnoses and procedures and whether the condition is 
ongoing, if applicable. 
 
6.3.2 
Diabetes History  
1. History of all medications used to treat diabetes (to be recorded in the concomitant 
medication form), including start date, duration of use, and stop date, if applicable.

2. History of complications due to diabetes, including nephropathy, retinopathy, 
neuropathy, non-traumatic amputations, and diabetic ketoacidosis, including date of 
diagnosis 
3. Frequency of hypoglycemic events (per week) that are symptomatic or require assistance. 
  
6.3.3 
Cardiovascular Disease History  
History of cardiovascular disease including presence of angina, congestive heart failure 
(including NYHA classification), known atherosclerotic cardiovascular disease, prior MI, 
transient ischemic attack or stroke, and prior cardiac or peripheral re-vascularization 
procedures. The history should include date of diagnosis and current status of diagnosis 
(resolved or ongoing). 
6.3.4 
Medication History  
1. Use of prescribed or non-prescribed medications, including name of medication, 
indications for usage, start and stop dates, dose, and frequency 
2. Use of supplements, including over the counter drugs, vitamins, herbal preparations, and 
dietary supplements within the past 30 days prior to screening. Each medication history 
will include the agent used, indication for usage, start and stop dates, dose, and 
frequency. 
 
6.4 
Diet and Exercise Counseling  
Subjects will receive counseling regarding an appropriate diet and exercise to aid in glycemic 
control based on standards of medical care in diabetes throughout the study. In addition, all 
subjects are encouraged to consume enough liquid to maintain adequate hydration. 
6.5 
Physical Examination  
A complete physical examination will be performed by the investigator at the time points 
indicated in the Schedule of Events (Appendix 1). The examination will include 
measurement of body weight, and a general assessment of all body systems including the 
skin, head, eyes, ears, nose, throat, neck, heart, lungs, abdomen, lymph nodes, and 
extremities. 
The body weight must be determined using a scale that is calibrated. Every effort should be 
made to use the same scale throughout the study duration. 
6.6 
Abbreviated Physical Examination  
An abbreviated physical examination will include body weight and height (height will be 
measured only at screening), and general assessment of the skin, heart, lungs and abdomen. 
Abbreviated physical examinations will be performed by the investigator at the time points 
indicated in the Schedule of Events (Appendix 1), unless clinically indicated. 

Bexagliflozin Tablets

The body weight must be determined using a scale that is calibrated. Every effort should be 
made to use the same scale throughout the study duration. 
6.7 
Vital Signs  
Vital signs will be measured at the time points indicated in the Schedule of Events 
(Appendix 1) and will include supine, sitting and standing blood pressure (BP) 
measurements, and heart rate. Only the BP measured in the sitting position will be used to 
determine eligibility. 
Devices designed to measure BP from the finger or wrist may not be used. The left arm and 
same cuff sizes should be used for each measurement at all visits. If the left arm cannot be 
used at the screening visit or during the study for BP measurements, the reason should be 
documented, and the right arm should be used for BP measurements for all subsequent visits. 
At each visit, BP measurements will be obtained using a calibrated sphygmomanometer 
while the subject is in sitting, supine, and standing positions. A single heart rate measurement 
should be taken just prior to the BP evaluation in the sitting, supine, and standing positions.  
All readings are to be entered into the source document and CRF for all subjects. The date 
and time of BP measurements should be captured in the source document and CRF. BP will 
be assessed first in the sitting position. Sitting BP and heart rate will be measured after the 
subject has been sitting for at least 5 minutes with feet on the floor and arm supported at 
heart level.  
After sitting BP measurement has been completed, supine and standing BP will be measured 
to evaluate orthostatic vital signs. Supine and standing blood pressure measures will not be 
used to determine eligibility for the study. First, the subject will lie flat for 5 minutes and 
have heart rate and supine blood pressure measured using the same equipment and arm as 
described for sitting BP. Once the supine BP measurement is complete, the subject will 
stand. Standing BP and heart rate will be measured after 2 minutes of standing. For standing 
BP measurements, the arm should be supported and extended such that the cuff is at heart 
level.  
6.8 
Electrocardiography  
A 12-lead electrocardiogram (ECG) will be conducted at the time points indicated in the 
Schedule of Events in Appendix 1 and whenever clinically indicated. This procedure should 
be performed in the supine position after at least 10 minutes of rest. ECG parameters 
measured will be the RR interval, PR interval, QRS duration, and QT interval. Each ECG 
should also be assessed by the investigator for signs of ischemia, clinically significant 
hypertrophy, and clinically significant T-wave abnormalities or arrhythmia.  
It is the investigator’s responsibility to review the results of the ECG as they become 
available. For each abnormal ECG result, the investigator shall ascertain if the observation 
represents 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 

Bexagliflozin Tablets

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, it is considered to reflect an AE. 
6.9 
Clinical Laboratory Tests  
6.9.1 
Laboratory Parameters 
Clinical laboratory tests are listed in Table 1. 
6.9.2 
Sample Collection, Storage, and Shipping 
6.9.2.1 
Hematology, Blood Chemistry, Serum Lipids, and Glycemic Control 
Assessments  
Blood samples for hematology, chemistry, serum lipids and glycemic control assessments 
will be collected.  Subjects will be in a seated or supine position during blood collection. 
Samples will be collected at the time points indicated in the schedule of events in Appendix 1 
and Appendix 2. 
The study staff will contact each subject prior to a scheduled clinic visit to confirm the time 
of the visit and to remind the subject of proper fasting practice. A subject must be queried to 
assess compliance with an approximately 10 hours fast prior to blood draw to ensure the FPG 
and triglycerides values can be accurately determined. If a subject has not fasted for 
approximately 10 hours, the subject must return as soon as can be arranged (within 1 week) 
to provide a specimen after proper fasting. Blood samples will be transported to the central 
lab for analysis. Samples should be stored and shipped as detailed in the Laboratory Manual. 
LDL-C will be calculated by the Friedewald equation. If triglycerides are > 400 mg/dL, the 
calculated LDL-C value is invalid by this equation and will be set as missing. Direct LDL-C 
will be determined in subjects whose triglycerides are > 350 mg/dL at screening visit. All 
subsequent LDL-C of these subjects will be determined by the same direct LDL-C 
measurements only. 
6.9.2.2 
Urinalysis  
Urine samples will be collected routinely at designated clinic visits from a clean catch 
sample. Urinalysis will be performed at the time points indicated in the schedule of events 
(Appendix 1 and Appendix 2). Investigator or staff should document if pre-menopausal 
female subjects are menstruating and note it in the source documents since hematuria is 
likely to be identified on dipstick urinalysis. 
Urine samples will be transported to the central laboratory for urinalysis. Samples should be 
stored and shipped as detailed in the Laboratory Manual. Microscopy will be conducted if the 
subject has a positive result on the leukocyte esterase or nitrite dipstick tests to clarify the 
significance of the finding.  Results of glucose measurement in the urinalysis must be 
suppressed from the laboratory reports so the sponsor, investigators, study coordinators,

pharmacists, study subjects, and the CEC members will remain blinded to the dosing 
assignment. 
In addition, strips to assess leukocyte esterase and nitrite but not glucose will be provided for 
immediate assessment at the clinical sites.  If more than traces of positive results are shown 
in the leukocyte esterase and /or nitrite testing, a urine culture should be performed in a 
designated laboratory regardless of patient reported signs or symptoms.  Results of the 
urinalysis and possible urine culture will be documented in the CRFs. 
Renal functional testing by UACR will be determined at time points specified in the schedule 
of events (Appendix 1 and Appendix 2).  
6.9.2.3 
Urine Pregnancy Test (UPT) 
UPT will be performed for all women, including surgically sterile or post-menopausal 
women, at the screening visit.  Additionally, women of child bearing potential (WOCBP) 
will receive a UPT at the clinical visits indicated in Appendix 2.

6.10 Diary and Glucometer Dispensation and Review 
A glucometer, testing strips, and a glycemic control diary will be provided to each subject at 
the start of OHA washout or when a potential subject starts taking run-in medications for 
SMBG.  Subjects will be trained to use the glucometer and record any events in the glycemic 
control diary.  The SMBG record from the glucometer and diary entries must be reviewed by 
the investigator at all subsequent visits including both phone interview and clinic visits. The 
SMBG record for all subjects should be sent to the site monitor once per month or as directed 
by the sponsor.  
During the SMBG training, symptoms that may indicate hypoglycemia, hyperglycemia, or 
ketoacidosis will be reviewed with study subjects.  Instructions to contact the clinic when the 
subjects experience potential hypoglycemia or diabetic ketoacidosis must be provided. 
6.11 Dispensing Run-in Drug  
Each eligible study subject will receive one bottle of run-in drug based on the scheduled visit 
outlined in Appendix 1.  
Patients should self-administer first dose of run-in drug with 250 mL of water under 
observation during the scheduled visit. 
6.12 Dispensing Investigational Product  
At randomization and at every 12 weeks of treatment thereafter, each study subject will 
receive one bottle of the investigational product based on the kit number assigned to the 
subject by the IWRS. One bottle of the investigational product will provide daily dosing for 
12 weeks. 
Patients should self-administer first dose of investigational product with 250 mL of water 
under observation during the scheduled visits, if they have not already taken investigational 
product that day. 
 
6.13 Adverse Events Assessments  
6.13.1 
Definition of Adverse Events  
Adverse event (AE): Any untoward medical occurrence in a subject administered a 
pharmaceutical product that does not necessarily have a causal relationship with the 
treatment.  
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not it is considered related to the medicinal product use.

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 this context refers to an event in which the subject 
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, 
• is a congenital anomaly/birth defect, or  
• is a medically important event or reaction.  
Medical and scientific judgment should be exercised in deciding whether other situations 
should be considered serious such as important medical events that might not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the 
subject or may require intervention to prevent one of the other outcomes listed in the 
definition above. These should also usually be considered serious. 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.  
Adverse Reaction: An adverse reaction means any adverse event caused by a drug. Adverse 
reactions are a subset of all suspected adverse events in which there is a reason to conclude 
that the drug caused the event. 
Unexpected Adverse Drug Reaction (UADR): An adverse reaction, the nature or severity 
of which is not consistent with the applicable product information (e.g., Investigator’s 
Brochure for an unapproved investigational medicinal product). 
Serious and Unexpected Suspected Adverse Reaction (SUSAR): The sponsor must report 
in an IND safety report any suspected adverse reaction to study treatment (i.e., including 
active comparators) that is both serious and unexpected (21 CFR 312.32(c)(1)(i)). Before 
submitting an IND safety report, the sponsor needs to ensure that the event meets all three of 
the definitions:  
• Suspected adverse reaction  
• Serious  
• Unexpected  
 
Severity: AEs will be graded on a 3-point scale and reported as indicated in the CRF. The 
intensity of an adverse experience is defined as follows: 
1 = Mild: event is medically significant but produces no disruption to daily activity; 
2 = Moderate: event is medically significant and reduces or affects normal daily activity;

Page 38 of 65 
 
3 = Severe: event is medically significant and results in inability to work or perform 
normal daily activity. 
 
Investigational Product Causality: An assignment made by the investigator based on the 
circumstances of the event and its analysis. Cases with causal relationship classified as 
possible, probable or definite are defined as related. Cases with causal relationship 
categorized as not likely or unrelated are defined as not related. Relationship of an AE to 
dosing will be assessed as follows: 
• Definite: The event responds to withdrawal of the investigational product (dechallenge), 
and recurs with rechallenge by administration of the investigational product. 
• 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 dechallenge response is 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 not a temporal or causal relationship to investigational product 
administration. 
 
6.13.2 
Eliciting and Reporting AEs  
The investigator will periodically assess subjects for the occurrence of AEs after subject 
consents to participation in the study. To avoid bias in collecting information about AEs, the 
investigator should ask subjects the following question: "How have you felt since you were 
last checked?" All AEs (serious and non-serious) reported by the subject must be recorded in 
the source documents and CRFs provided by the sponsor. 
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 the laboratory value is determined to 
be a clinically significant and abnormal change from baseline for that subject, this is 
considered a laboratory AE. 
Hypoglycemia is defined as any FPG or SMBG value ≤ 70 mg/dL and should be documented 
based on the ADA hypoglycemia categories. 
Any increase in liver function tests (AST, ALT, or bilirubin) greater than 3 times the ULN 
for the laboratory utilized will be considered a laboratory AE. 
In addition, the sponsor’s Medical Monitor and designated personnel must be notified 
immediately by telephone, email, or fax of any immediately reportable AEs (IRAE) 

Bexagliflozin Tablets 
 
Theracos Sub, LLC 
Clinical Trial Protocol:

Page 39 of 65 
 
according to the procedure outlined below. Special attention should be paid to recording 
hospitalization and concomitant medications. 
6.13.3 
Immediately Reportable AEs  
The investigator must report any SAE to the sponsor or its representative immediately after 
the investigator becomes aware of the event. An SAE form should be completed and sent to 
the sponsor within 24 hours of knowledge of the event. 
Non-serious events that require discontinuation of investigational product (including 
laboratory abnormalities) should be reported to the sponsor within 3 working days. The CRF 
AE form should be completed and sent to the sponsor. 
Subjects experiencing an SAE should be followed clinically until their health has returned to 
baseline status or no further improvement in condition can be expected with further care. It is 
expected that the investigator will provide or arrange appropriate supportive care for the 
subject. 
6.13.4 
Pregnancy  
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 be enrolled or remain in the study. If 
pregnancy is suspected while the subject is receiving study treatment, the investigational 
product must be withheld immediately until the result of the pregnancy test is known. If 
pregnancy is confirmed, the investigational product will be permanently discontinued and the

subject will be withdrawn from the trial. (Exceptions to study discontinuation may be 
considered for life-threatening conditions only after consultations with a sponsor Medical 
Monitor or designated personnel.) The investigator must notify the Medical Monitor within 3 
working days of any female subject who becomes 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 
sponsor’s clinical or designated personnel. 
Protocol required procedures for study discontinuation and follow-up must be performed on 
the subject unless contraindicated by pregnancy (e.g., x-ray studies). Other appropriate 
pregnancy follow-up procedures should be considered if indicated. In addition, the 
investigator must report to the sponsor, on the appropriate Pregnancy Surveillance Form, 
follow-up information regarding the course of the pregnancy, including perinatal and 
neonatal outcome. Infants will be followed for a minimum of six months. 
6.13.5 
Procedure for Breaking the Blind  
As indicated in Section 5.5 above, the sponsor, medical monitor, study coordinators, 
pharmacists, study subjects, and the CEC members will be blinded to the treatment 
assignment during the study period. The investigator should also remain blinded to the 
subject treatment during the entire study unless knowledge of the subject’s treatment is 
required for clinical care and safety. The Emergency Code Break module in the IWRS is 
used for such situations. The investigator must confirm the intention to unblind the subject’s 
treatment to obtain the dose information in IWRS. Upon completion of the unblinding, the 
system will send an alert to designated study team members that an unblinding event has 
occurred. Documentation of breaking the blind should be recorded in the subject’s medical 
record with the date and time the blind was broken, and the names of the personnel 
requesting and authorizing unblinding. The treatment assignment will continue to be 
withheld from the CEC members until all phase 3 studies are completed. 
6.13.6 
Follow-up of Non-Serious AEs  
Non-serious AEs that are identified on the last scheduled contact must be recorded in the AE 
CRF with the current status noted. All non-serious events that are ongoing at the time will be 
recorded as ongoing in the CRF. 
6.13.7 
Follow-up of Post-Study SAEs  
SAEs that are identified on the last scheduled contact must be recorded on the AE CRF page 
and reported to the sponsor according to the reporting procedures outlined in Section 6.13.3. 
These may include unresolved previously reported SAEs, or new SAEs. The investigator 
should follow these SAEs 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 the sponsor 
until the event has been resolved.  

Bexagliflozin Tablets 
 
Theracos Sub, LLC 
Clinical Trial Protocol:

Confidential 
Page 41 of 65 
 
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 sponsor or designated personnel. This 
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 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 4 weeks after the last treatment. 
6.13.8 
Urinary Tract Infections (UTIs)  
Events potentially representing UTIs, including cystitis, urethritis, pyelonephritis, or 
urosepsis, should be carefully evaluated and documentation of signs, symptoms, culture 
results for infectious agent, and treatment should be undertaken when appropriate.  
The investigator should query the subject at every clinical visit for symptoms that may be 
related to a UTI and, if appropriate, document these events as symptomatic UTI in the CRF 
unless an alternative diagnosis is present. In addition, a clean catch urine sample will be 
obtained at all clinical visits and a urinalysis will be performed on that sample at every 
clinical visit. A positive urinalysis will be defined as one with detectable leukocyte esterase 
and/or nitrites (1+ or greater). If the subject reports symptoms consistent with a UTI or the 
urinalysis at the clinical site is positive, a urine culture will be performed in a designated 
laboratory. A positive urine culture will be defined as one with ≥ 105 CFU of any species. 
The investigator may also perform a urine culture using local resources if necessary for 
clinical care.  
6.13.9 
Genital Mycotic Infections (GMIs)  
The investigator will query the subjects for signs or symptoms that may represent a GMI at 
all clinic visits. GMIs will be diagnosed based on symptoms and, if appropriate, physical 
exam and laboratory findings. Investigators must exclude the possibility of sexually 
transmitted infections before diagnosing GMI. Diagnosis of GMIs must be documented in 
the CRF. 
6.13.10 Hepatotoxicity  
If plasma AST and/or ALT concentrations > 3 x ULN are detected, the investigator will 
record in the source documents the date corresponding to the date of the laboratory 
abnormality; the type, frequency, and dose of any concurrent medications or supplements 
taken by the subject within the 14 days of the detected abnormality; and any symptoms or 
change in physical exam that have occurred since the prior assessment. The investigator 
should perform additional laboratory and imaging tests to attempt to establish the cause of 
the AST and ALT elevations, including ruling out any potential contribution from bone or 
muscle etiologies. 
Any clinically significant increase in hepatic enzymes and specifically any ALT or AST 
> 3 x ULN requires immediate repeat test within 48 to 72 hour to confirm the hepatic enzyme 

Bexagliflozin Tablets

Page 42 of 65 
 
elevation and should be repeated based on the clinical situation at least every 96 hour (4 
days) until ALT and AST return to < 2.5 x ULN. Study medication should be stopped and the 
event should be reported as a laboratory AE within the CRF if the enzyme elevation is 
confirmed or worsening.  
Hepatotoxicity will be diagnosed and entered as an AE should any of the following occur: 
• ALT or AST > 8 x ULN; 
• ALT or AST > 3 x ULN and total bilirubin > 2 x ULN or INR > 1.5 
• ALT or AST > 3 x ULN with the appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (> 5%). 
 
In the event of hepatotoxicity, investigational product should be permanently discontinued. 
The investigator is encouraged to consult with the Medical Monitor regarding diagnostic 
evaluation for the hepatic enzyme elevations. Consultation with a hepatologist may also be 
appropriate in some circumstances. 
6.13.11 Hypoglycemia  
Events of hypoglycemia or potentially representing hypoglycemia should be carefully 
evaluated.  
All subjects will be provided with a glucometer and glycemic control diary in which to 
record symptoms related to any hyper- or hypoglycemic events. During the study the subject 
is expected to record all signs and symptoms that may potentially reflect hypoglycemia. In 
the event of such signs or symptoms, the subject is expected to check the blood glucose if it 
is reasonably safe to do so, and consume carbohydrates, if appropriate, to treat 
hypoglycemia.  
The subject will be expected to record in the glycemic control diary the following 
information for each hypoglycemic event: 
1. Signs and symptoms attributed to hypoglycemia and the time and date on which they 
occurred  
2. SMBG reading at the time of the signs and symptoms attributed to hypoglycemia 
3. Time elapsed from the most recent meal to the onset of signs and symptoms 
4. Duration, intensity, and type of any exercise within the 24 hour prior to the signs and 
symptoms 
5. Type of treatment used (e.g., juice, crackers) for the signs and symptoms and whether 
assistance was required from another person to administer the treatment 
6. SMBG reading 15 minutes after treatment with carbohydrate and the time at which 
this was measured 
7. Whether or not the signs and symptoms attributed to hypoglycemia resolved after 
blood glucose returned to normal. 
 

Bexagliflozin Tablets 
 
Theracos Sub, LLC 
Clinical Trial Protocol:

Page 43 of 65 
 
Subjects are encouraged to call the study clinic should signs and symptoms potentially 
related to hypoglycemia occur. 
At each study visit, the investigator is expected to review the glucometer and glycemic 
control diary with particular attention to any SMBG value ≤ 70 mg/dL and any recorded 
signs or symptoms potentially related to hypoglycemia. In addition, the investigator should 
query the subject with regard to the occurrence of signs and symptoms potentially related to 
hypoglycemia even if none are recorded in the diary.  
In the event of a blood glucose value ≤ 70 mg/dL or signs and symptoms potentially related 
to hypoglycemia, the investigator should complete the supplemental CRF which will include 
data from the glucometer, and glycemic control diary as well as action items to reduce future 
hypoglycemia episodes.  
Hypoglycemia events will be recorded in the hypoglycemia log under 5 categories: 
1. Severe hypoglycemia: an event requiring assistance by another person to actively 
administer carbohydrate, glucagon, 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 SAEs in the CRF. 
2. 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).  
3. Asymptomatic hypoglycemia: an event not accompanied by typical symptoms of 
hypoglycemia but with a measured blood glucose concentration ≤ 70 mg/dL 
(3.9 mmol/L).  
4. Probable symptomatic hypoglycemia: an event during which symptoms of 
hypoglycemia are not accompanied by a blood glucose determination but that is 
presumably caused by a blood glucose concentration ≤ 70 mg/dL (3.9 mmol/L). 
5. 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). 
 
While each event meeting the criteria above will be entered into the hypoglycemia log, only 
severe hypoglycemia, documented symptomatic hypoglycemia, asymptomatic hypoglycemia, 
and probable hypoglycemia will be entered as AEs.  
In the event of asymptomatic hypoglycemia, the investigator should review the signs and 
symptoms of hypoglycemia with the subject to elicit a complete description and should 
review proper glucometer technique to ensure that the low glucose value is not due to 
improper use of the glucometer. 

Bexagliflozin Tablets

The investigator should be alerted to the likelihood of improper glucose measurement 
technique if a study subject reports an SMBG value ≤ 55 mg/dL (3.1 mmol/L) that is not 
associated with any signs or symptoms of hypoglycemia and is not treated by some form of 
glucose administration.  
In the event of probable symptomatic hypoglycemia, the investigator should encourage the 
subject to obtain glucose values, when possible, in the context of signs and symptoms of 
hypoglycemia, even if the glucose value is measured after treatment for the symptoms is 
administered. 
If hypoglycemia occurs in any subject prescribed rescue medication for hyperglycemia 
during the study, the total daily dose of the rescue medication should be reduced 50% or 
more at the discretion of the investigator. 
6.13.12 Diabetic Ketoacidosis (DKA) 
DKA is a serious, acute complication of diabetes and can be life-threatening.  Subjects will 
be educated on the signs and symptoms of DKA and are required to call the study clinic and 
seek treatment should such signs and symptoms occur. 
During the clinical trial period, potential DKA will be monitored by the routine measurement 
of urinary ketones and assessment for signs or symptoms of acidosis at every clinic visit. 
Clinical presentations, such as difficulty breathing, abdominal pain, nausea, vomiting, 
lethargy, or a fruity smell in the breath, or laboratory values that suggest clinically-significant 
acidosis should be documented; treatment of DKA should be provided when appropriate.  
If ongoing symptoms or signs suggest a possible DKA, the investigator should perform 
relevant laboratory testing while directing appropriate medical care for the subject. If DKA is 
suspected, regardless of the blood glucose level, the following assessments should be done 
immediately: physical exam and serum glucose, bicarbonate, electrolytes, and serum ketones 
measured STAT at a local laboratory. If ketoacidosis is likely, investigational product 
administration should be discontinued and immediate appropriate medical therapy, including 
insulin, should be initiated.  A glucose infusion may be provided if necessary to avoid 
hypoglycemia during insulin therapy. Insulin treatment should continue until resolution of 
the ketoacidosis and stabilization of the subject’s clinical condition. Investigational product 
administration may be resumed following stabilization of the subject’s condition. 
Investigator should collect the data necessary for the completion of the DKA CRF. 
If symptoms suggestive of DKA may have occurred but are not ongoing, investigator should 
review available data in order to complete the DKA CRF.  The investigator may also perform 
laboratory assessment using local resources if necessary for clinical care. 
6.13.13 Major Adverse Cardiovascular Event (MACE) 
Evaluation of MACE will be undertaken across the development program for bexagliflozin. 
All MACE reports should also be captured as SAEs and every effort will be made to ensure 
that events recorded as MACE are coded in a similar manner within the safety database. The 
SAE listing will also be reviewed periodically by the CEC members to identify potential 

Bexagliflozin Tablets

Page 45 of 65 
 
MACE that may not have been reported by the site investigators. All subjects will be 
followed by investigators for MACE for the duration of the study even if study medication 
has been permanently withdrawn. 
The independent CEC will receive and adjudicate the following events.  
• 
All deaths 
• 
Suspected non-fatal myocardial infarction (MI) 
• 
Suspected hospitalization for unstable angina (HUA) 
• 
Suspected transient ischemic attack (TIA) and stroke  
• 
Suspected hospitalization for heart failure (HF) 
• 
Reported coronary revascularization procedure 
 
6.13.14 Amputation 
Amputation and related adverse events will be recorded in a dedicated case report form. 
During each study visit, the investigator should query the subject for any amputation and 
related adverse events and procedures. Investigators are reminded to counsel appropriate foot 
care to avoid cuts or sores and to treat even minor cuts or sores to prevent infection and 
ulceration. Patients who have had a previous amputation should be closely monitored. 
Special attention may be appropriate for patients who are also receiving thiazide diuretics as 
these have been shown to increase the risk of amputation in diabetics.  
6.14 Concomitant Medication Assessments  
A concomitant medication is any medication that the subject has been taking prior to 
enrollment and that the subject is expected to continue to take 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.  
The medications or treatment for controlling hypoglycemia must be recorded as concomitant 
medications in the CRF. Any medication given to treat hyperglycemia and continued for 
more than 2 weeks is considered a rescue therapy and should be recorded in the concomitant 
medication log. 
Changes from baseline anti-hypertensive therapy and their rationale must be recorded in the 
CRF. 
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 complete the study.  
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.

7.13 Early Termination Procedures 
Subjects removed from the study due to drug related toxicity will be followed until resolution 
or stabilization of the adverse event. The sponsor must be notified in the event that a subject 
withdraws or is withdrawn from the study.  
To minimize the effect of missing values on data analysis and study outcome interpretation, 
every effort should be made to prevent missing data.  Site staff should explain that 
withdrawing consent is the study subjects’ decision and emphasize to the subjects the 
importance of continued participation to complete the full study. If study subjects express 
dissatisfaction with the trial conduct and have not withdrawn yet, the investigator shall make 
efforts to address the subjects’ concerns, explain the impact of withdrawal on the study 
outcomes, and retain subjects in the study to the best of her or his ability. In doing so, the 
investigator must be careful to avoid coercion. 
Subjects who withdraw consent and have received investigational product will have a follow-
up examination, including a complete physical examination, vital signs, ECG, and clinical 
laboratory tests (hematology, serum chemistry, and glycemic control). Study investigators 
shall understand the value of data collection after early termination and make effort to 
collecting data after a subject discontinues the study treatment.

PLANNED STATISTICAL METHODS 
9.1 
General Considerations 
The following sections provide a summary of the planned analysis of the trial but a complete 
statistical analysis plan will be developed as a separate document and will become the final 
plan. All statistical analyses will be performed using SAS Version 9.4 or higher.   
Data summaries will use descriptive statistics (number of subjects [N], mean, standard 
deviation [SD], Q1, median, Q3, minimum and maximum) for continuous variables, and 
frequency and percentage of subjects for categorical and ordinal variables.  If there are 
missing values, the number missing will be presented, but without a percentage. 
Unless otherwise specified, all statistical tests will be two-tailed using a 0.05 level of 
significance.  All confidence intervals (CIs) will be two-sided 95% confidence intervals. 
9.1.1 
Multiple Comparisons / Multiplicity 
A sequential testing procedure will be used to control familywise error rate for the primary 
efficacy endpoint and key secondary efficacy endpoints at a two-sided 5% significant level. 
The key secondary efficacy endpoints will be tested only if the primary efficacy measure 
achieves significance. 
9.2 
Determination of Sample Size 
Approximately 210 subjects will be randomized 2:1 to bexagliflozin tablets, 20 mg or 
bexagliflozin tablets, placebo.   
The sample size calculation for this study was based on a two group t-test with a two-sided 
significance test at the 5% level and the following assumptions:  
1. The difference in mean change from baseline to week 24 in HbA1c in the bexagliflozin 
group compared to that of the placebo group will be -0.5%.   
2. The standard deviation for the difference in mean change from baseline to week 24 in 
HbA1c between the bexagliflozin group and the placebo group will be 1.0%. 
 
Under the above assumptions, an estimated sample size of 128 and 64 evaluable subjects in 
the bexagliflozin and placebo arms, respectively, yielded a 90% power that bexagliflozin 
treatment will be found to be significantly different from placebo. To account for an 
estimated drop-out rate of approximately 10%, the study design anticipates randomizing 140 
and 70 subjects in the bexagliflozin or placebo arm, respectively. 
This study will be conducted at multiple investigative sites and will likely randomize 
different numbers of subjects at each site.  Enrollment will be on a competitive basis but will 
be capped at 21 subjects from any one site.

9.3 
Analysis Populations  
9.3.1 
Intention to Treat Analysis Set 
All subjects who are randomized will be included in the Intention to Treat (ITT) Analysis 
Set. All analyses of the ITT Analysis Set will be based on the randomization schedule. The 
ITT analysis set will serve as the primary set for the efficacy analyses.  
9.3.2 
Safety Analysis Set 
All subjects who are randomized and take at least one dose of double-blind study medication 
will be included in the Safety Analysis Set (SAS). Safety analyses will be based on the 
medication that each subject has taken. The SAS is the primary analysis set for safety 
evaluation.  
9.3.3 
Per Protocol Analysis Set 
The Per Protocol (PP) Analysis Set will include all subjects in the ITT who meet the study 
eligibility requirements and have no major protocol deviations that affect the validity of the 
efficacy measurements. Protocol deviations that may result in subject exclusion from the PP 
Analysis Set will be detailed in the Statistical Analysis Plan. The PP analysis set will serve as 
the secondary set for efficacy assessment. 
9.4 
Demographics and Baseline Characteristics 
Subjects must meet all of the inclusion criteria and none of the exclusion criteria in order to 
participate in the study. Demographic characteristics include age, gender, race, ethnicity and 
country of investigational site. Baseline characteristics will be determined at Visit 5 and 
include HbA1c, blood pressure, body weight, BMI, FPG, duration of diabetes from diagnosis 
to V1, and stratification factors including HbA1c values at V5 and background anti-diabetic 
treatment status (treatment naïve or not). Summary descriptive statistics by treatment will 
include counts and percentages for discrete variables and estimation of means, standard 
deviations, medians, inter-quartile range, minimum, and maximum for continuous variables. 
Baseline is defined as the last non-missing value before randomization date. 
9.5 
Primary Efficacy Analysis 
Efficacy data include HbA1c, FPG, body weight, and blood pressure. All changes from 
baseline will be calculated as the post-treatment value minus the last non-missing assessment 
before randomization (Visit V5).   
9.5.1 
Primary Efficacy Endpoint 
The primary efficacy hypothesis is that bexagliflozin reduces HbA1c after 24 weeks of 
treatment when compared to placebo. The analysis of the change in HbA1c at week 24 will 
be based on ITT Analysis Set using all observed data and a mixed model repeated measures 
(MMRM) approach that will include terms for treatment, visit, treatment-by-visit interaction 
and randomization stratification factors as fixed effects and the baseline HbA1c value as a

fixed effect covariate. Least squares mean treatment differences between the bexagliflozin 
group and the placebo group at week 24 will be estimated from the model with the 
corresponding p-values and their two-sided 95 % CI presented. An unstructured covariance 
will be used to model the within-subject correlation. If the model with the unstructured 
covariance structure does not converge, an autoregressive(1) covariance structure will be 
used. HbA1c values obtained after the start of rescue medication will not be excluded from 
the analysis. 
Sensitivity analyses will be performed as: 
1. A multiple imputation method will be used to impute missing observations (including 
observations obtained after rescue medication) in the ITT Analysis Set prior to carrying 
out the MMRM analysis. 
2. A multiple imputation method will be used to impute missing observations (not including 
observations obtained after rescue medication) in the ITT Analysis Set prior to carrying 
out the MMRM analysis.  
3. A last observation carried forward (LOCF) method will be used to impute the missing 
observations in the ITT Analysis Set prior to carrying out the MMRM model. 
 
For supportive analyses, the primary efficacy endpoint will be analyzed with observed 
available data using the PP analysis set in a similar manner as above. 
9.5.2 
Handling Dropouts and Missing Data 
Randomized subjects who withdraw consent to participate in the study will not be replaced. 
The early termination rate is estimated to be 10%. To the extent possible, attempts will be 
made to minimize the amount of missing data through measures planned in the study 
conduct. But if data are missing for the primary endpoints, they will be handled as follows: 
1. Only available data will be analyzed and data obtained after rescue will not be excluded. 
This will be considered the primary analysis. 
2. Missing endpoint information will be imputed by a multiple imputation linear regression 
approach for continuous variables. Adequate imputed datasets will be generated, and the 
corresponding primary analyses will be carried out on each imputed dataset; the results 
will be combined across the datasets using the standard techniques for multiple imputed 
data sets in order to yield overall treatment comparison results using the imputed data. 
 
The number, timing, pattern, reason for and possible implications of missing values in 
efficacy assessments will be investigated. The dropout patterns will be assessed by Kaplan-
Meier plots if applicable to assess whether they differ between treatment groups. 
For all other endpoints, the missing data will not be imputed and only the observed data will 
be used in the analyses.

9.6 
Secondary Efficacy Endpoints 
9.6.1 
 Key secondary Efficacy Endpoints 
The key secondary efficacy endpoints include: 
• Change in SBP from baseline to week 24  
• Change in body weight from baseline to week 24 in subjects with a BMI ≥ 25 kg/m2 
 
A hierarchical testing procedure will be applied to these endpoints in the sequence provided 
above. These key secondary endpoints will only be tested sequentially when significant 
treatment differences are established for the primary efficacy endpoint in the comparisons 
between the bexagliflozin and placebo groups. 
The comparison between randomized treatments at week 24 in SBP will be carried out using 
the MMRM ANCOVA model with unstructured covariance assumption. The model will 
include terms for treatment, visit, treatment-by-visit interaction, and randomization 
stratification factors as fixed effects and the corresponding baseline SBP value as an 
additional fixed effect covariate. Treatment comparison p-values and the least square mean 
difference at week 24 will be estimated from the model, with the two-sided 95 % CIs of the 
difference also presented. If the model does not converge with the unstructured correlation 
assumption, an autoregressive(1) model will be used. 
Change from baseline in body weight at week 24 will be analyzed using ANCOVA method. 
9.6.2 
Exploratory Efficacy Endpoints 
The exploratory secondary efficacy endpoints include: 
• Change from baseline in HbA1c over time 
• Proportion of subjects reaching HbA1c < 7% over time 
• Change from baseline in FPG over time 
 
For changes from baseline in HbA1c, FPG over time, a similar MMRM ANCOVA model 
will be used as for the key secondary efficacy endpoint of change in SBP at week 24 in 
subjects with baseline SBP ≥ 130 mmHg (the treatment-by-visit interaction term will be 
removed if not significant). Of interest in the MMRM ANCOVA model is the difference 
between treatments on these endpoints across all post-baseline time points. Also, changes 
from baseline for each endpoint will be estimated and analyzed at each study visit using this 
MMRM model. Specifically, for each endpoint, treatment difference in least squares means 
will be estimated by visit from the model with the corresponding p-values and the two-sided 
95% CIs of the difference between treatments. 
Endpoints measuring proportions over time will be analyzed using generalized estimating 
equation logistic regression using similar independent variables as the MMRM ANCOVA 
models above (the treatment-by-visit interaction term will be removed if not significant), and 
using an unstructured correlation structure (or autoregressive(1) if the model with the

unstructured structure does not converge). Of interest is the difference between treatments 
across all post-baseline time points. Also, odds ratios will be estimated from the model with 
the corresponding p-values and their two-sided 95% CIs presented at each visit. 
9.7 
Analysis of Safety 
Safety data include AEs, physical exam results, vital signs, ECG results, and clinical lab 
results including serum chemistry, hematology, serum lipids, glycemic control parameters 
and urinalysis. Observed data will be summarized by treatment group as counts and 
percentages for discrete variables and means, standard deviations, medians, inter-quartile 
range, minimum, and maximum for continuous variables. All subjects who are randomized 
and receive at least one dose of double-blind study medication will be included in the safety 
analysis. All safety data will be presented in by-subject listings and included in the clinical 
trial report. 
9.7.1 
Adverse Events 
AEs will be mapped to preferred term and body system using the Medical Dictionary for 
Regulatory Activities (MedDRA) dictionary. AEs that begin after the first administration of 
double-blind study medication or existing AEs that worsen after the first dose of double-
blind study medication are considered treatment emergent AEs (TEAE). The number and 
percentage of subjects reporting TEAEs will be summarized for each treatment group by 
MedDRA system organ class and preferred term, then by severity, and by relationship to 
study treatment. Drug-related adverse events will be considered those to be at least possibly 
related to bexagliflozin administration based on the investigators assessment.  
The number and percentage of subjects reporting serious AEs, and the number and 
percentage of subjects reporting AEs leading to treatment discontinuation will also be 
summarized for each treatment group by MedDRA system organ class and preferred term.  
Adverse event listings will be provided for the following subsets: 
1. TEAEs 
2. All TEAEs at least possibly related to bexagliflozin 
3. Serious AEs  
4. AEs leading to treatment discontinuation  
5. AEs leading to death  
 
9.7.2 
Adverse Events of Special Interest  
AE of special interest include UTI, GMI, diuretic effects, hepatotoxicity, cardiovascular 
events, hypoglycemia, fracture, malignancy, hypersensitivity reactions, hypotensive 
episodes, acid-base disorders, renal failure events, and amputations. These AEs of special 
interest will be prospectively identified based on the MedDRA preferred terms in the adverse 
event log by a medical expert prior to the data base lock and unblinding of the individual 
subject treatment assignment.  The list of adverse events of special interest will be confirmed 
in a peer review process.

The number and percentage of subjects experienced TEAE of special interest will be 
summarized for each treatment group by types of events. The incidence rate of AE of special 
interest per 100 patient years will also be summarized.  Additional analyses will be specified 
in the statistical analysis plan to evaluate other event associated safety parameters and 
potential risks in subpopulations based on age, gender, or other baseline characteristics. 
9.7.3 
Clinical and Laboratory Events and Analyses 
Clinical and laboratory metrics will be measured at the time points indicated in the Schedule 
of Events (Appendix 1). These measurements include vital signs, clinical laboratory (see 
Section 6 for a complete list) and ECGs. These data will be summarized as actual values and 
changes from baseline by treatment for each visit for selected parameters. 
Laboratory data will be classified as low, normal or high relative to the parameter’s reference 
range.  Laboratory abnormalities for each treatment will also be summarized with shift tables 
for selected parameters. 
All clinical laboratory, ECG and vital sign data will be listed. 
9.7.4 
Physical Examination 
Physical examination findings will be presented in a by subject listing.  
9.7.5 
Concomitant Medications 
Concomitant medications will be coded using the World Health Organization Drug 
Dictionary (WHO-DD).  A by-subject listing of concomitant medications will include all 
medications taken during the study regardless of the timing for the start of the medication.  
All medications started prior to the administration of the investigational product will be listed 
and flagged as prior in the listing. Only the concomitant medications will be summarized by 
ATC term and treatment. 
9.8 
Interim Analysis 
No interim analysis will be performed during this study.  
9.9 
Final Analysis 
After all subjects have completed the planned 24 weeks of blinded study treatment and the 
subsequent follow-up period, the final analysis of the clinical study will be completed.  At 
this time, the database will be cleaned and locked, and the treatment codes will be unblinded.

development program. The safety review activity and potential risk benefit assessments 
utilized by the DSMB will be defined in its charter. 
10.9 Protocol Violations/Deviations 
It is important to conduct the study according to the protocol. Protocol deviation waivers will 
not be prospectively granted by the sponsor. If minor protocol deviations occur, the 
investigator must decide the most appropriate way to proceed with study activities and 
should consult the study representative for assistance. If major protocol deviations occur, the 
sponsor’s medical monitor must be notified immediately 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 can there be 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 investigator must 
notify the Sponsor. 
Protocol violations/deviations must be reported in the final study report.
