1. INTRODUCTION AND RATIONALE 
Sodium-dependent glucose cotransporter 2 (SGLT2) is mainly expressed in human kidneys and small intestinal cells. 
In the proximal tubule of the nephron SGLT2 is responsible for the reabsorption of approximately 90% of the filtrated 
glucose. Inhibition of SGLT2 was shown to increase renal glucose excretion and to lower glucose. Subsequently, a 
number of SGLT-2 inhibitors were developed and are currently approved for the treatment of type 2 diabetes. CV 
outcome trials, required by the European Medicines Agency (EMA) and Federal Drug Administration (FDA) have 
proven additional beneficial effects on cardiovascular outcome in various compounds of that class. Empagliflozin 
could even show significant positive effects on mortality(1). More consistent and most pronounced was the effect of 
reducing heart failure hospitalisation. Most recently, data of dapagliflozin was published (DAPA-HF)(2) extending 
these beneficial effects to non-diabetic heart failure patients, significantly reducing the primary endpoint of CV death 
and worsening heart failure as well as CV-mortality alone and even all course mortality.  
As dose-response modelling indicates that ertugliflozin 5 mg and 15 mg result in near maximal urinary glucose 
excretion (UGE) in patients with type 2 diabetes mellitus, providing 87% and 96% of maximal inhibition, respectively 
(product information Steglatro), the lower dose can be expected to be comparably efficient and will therefore be 
used in this study. This is also confirmed by the data of a recent pooled analysis of previous phase III trials with 
ertugliflozin showing a reduction in HbA1c of only 0.1% (3). 
Ventricular arrhythmias are a typical feature of advanced heart failure with reduced ejection fraction (HFrEF) or heart 
failure with mid-range ejection fraction (HFmrEF), and account for a large proportion of cardiac death in this 
population. Implantation of an ICD is a class IA recommendation in the ESC heart failure guidelines both in secondary 
prevention and primary prevention (IB for DCM patients)(4). Additional CRT function is a class IA recommendation in 
all of these patients with QRS duration >150ms in sinus rhythm(4). Since arrhythmias occur independent of the type 
of cardiomyopathy (ischemic, dilative, idiopathic) the unifying phenotype of altered contractility and elevated 
diastolic pressure and potentially increased systemic inflammation itself must be regarded as the trigger of these 
arrhythmias(5).  
Therefore, every improvement of heart failure should result in a reduction of ventricular arrhythmias. This has been 
shown extensively for beta-blockers(6), aldosterone-antagonists(7; 8), and ARNIs(9; 10). Large outcome studies with 
ACE inhibitors did only give limited insight in the type of arrhythmic events, their causes, and the effect of the 
treatments(11; 12), while studies analysing the rate of ventricular arrhythmias did show a significant reduction in 
these events(13). 
Previous data showed that SGLT-2 inhibitor dapagliflozin (DAPA-HF) improved primary outcome in a HFrEF 
population comparable to sacubitril/valsartan in the PARADIGM trial(9) (both trials with a NNT of 21). Therefore, a 
comparable impact on heart failure morbidity and ventricular arrhythmias can be assumed for both drugs. Moreover, 
Martens et al. reported on a highly significant reduction of ventricular arrhythmias after initiation of 
sacubitril/valsartan in a retrospective analysis of 151 patients with an observation period of 6 months. The number 
of VT/VF episodes declined by more than two thirds(10).  
Mortality in patients on ICD therapy is high despite optimal medical treatment. The study by Martens is a 
retrospective analysis of data of patients that were followed throughout the observation period of 364 days.

Therefore, severely ill patients and at least those who died within these 12 months were not analysed. Obviously, 
these patients tend to have the highest burden of ventricular arrhythmias. Therefore, event rate in the Martens study 
is underestimated.  
More reliable data on event rates derive from prospective randomized trials such as the RAFT study. They report a 
rate of VTs of ~2 per year (11278 appropriate ICD detections in 5953.6 patient-years of follow-up) in a cohort of 
patients with severely reduced left ventricular ejection fraction (<30%).  
Within another increased-risk population treated in the SHIELD trial 58% of the placebo-group experienced “all-cause 
shocks plus symptomatic tachyarrhythmias terminated by ATP”. The overall number of episodes was 1595 in 214 
patients (average of ~7.5/patient and year).  
1.1 Aim of the study 
The aim of this mechanistic study is to investigate the impact of ertugliflozin on the ventricular arrhythmic burden, 
physical function, quality of life and biomarkers in heart failure in patients with ICD±CRT therapy.  
1.2 Study hypothesis 
Treatment with the SGLT-2 inhibitor ertugliflozin will reduce sVT/VF episodes more effectively than placebo within 
12 months. 
2. OBJECTIVES AND OUTCOMES

3. STUDY DESCRIPTION 
3.1 Design  
This is a randomized, double-blind (patients and physicians), placebo controlled multi-center study to evaluate the 
effect of ertugliflozin 5mg once daily (p.o.) for 52 weeks on the ventricular arrhythmic burden and markers of physical 
and mental well-being as well as biomarker for heart failure in HFrEF and HFmrEF patients with ICD±CRT therapy. 
The study will be conducted in 8 experienced sites in Austria with an aim to enrol 402 patients (Figure 1) to evaluate 
the overall study hypothesis.

▪ 
Pregnancy or intention of becoming pregnant 
▪ 
Intolerable adverse effects 
▪ 
Major violation of the study protocol 
▪ 
Occurrence of an exclusion criterion 
▪ 
Other circumstances that would endanger the health of the subject if he/she were to continue his/her 
participation in the trial. 
Reasons for withdrawals and discontinuation of any subject from the protocol have to be recorded. 
4.4 Termination of the entire trial 
Premature termination of the clinical trial will be considered when the risk-benefit ratio changes markedly for the 
patient, the use of the study medication is no longer justifiable, the sponsor believes it is necessary to terminate the 
clinical trial for safety reasons, when early evidence of the superiority or inferiority of a treatment group is obtained 
by an interim analysis after 25 and 50% of patients completed the trial, or by other research results, or when the 
clinical trial proves to be impracticable. 
4.5 Unblinding 
In the case of a requirement to unblind study medication, one of the chief investigators needs to be informed to 
discuss the unblinding. The unblinding list is held by the Institute of Medical Informatics, Statistics and 
Documentation (IMI), Medical University of Graz, which is not involved in study investigations. 
5. VISIT PROCEDURES, MEASUREMENTS AND ASSESSMENTS  
5.1 Recruitment and screening 
Sites will recruit competitively and sites will receive compensation for their work based on a per-patient fee. The 
clinic staff of the EP/arrhythmia service informs patients about the possibility of being enrolled in this study. No 
study-related procedures are undertaken before obtaining informed consent. The study team in detail explains the 
study procedures and asks the participant about their willingness to participate in this research study. After informed 
consent is signed and obtained, participants are given a signed copy of the informed consent document and are 
assigned a screening identification number.  
After obtaining informed consent at the screening visit, subject´s eligibility will be further assessed and documented 
by using a source data form with a list of inclusion and exclusion criteria, medical history (including all medications 
past and current) will be acquired and the following measurements will be performed: body weight, height, blood 
pressure, ECG and blood parameters (see Table 2). Laboratory results up to 14 days before screening can be used to 
test eligibility for the trial. 
Subjects unable to provide written informed consent will not be included in the study.

5.2 Randomisation 
After screening, all eligible patients for the trial will be randomised into one of the two arms of the study via 
Randomiser Software (Institute for Medical Informatics, Statistics and Documentation, Medical University of Graz, 
http://www.randomizer.at), which will be programmed with a randomisation schedule provided by an independent 
statistician. The randomisation will be stratified by site, by type 2 diabetes and by eGFR < 60 vs ≥ 60. 
Only the subject number will be recorded in the case report form (CRF). The investigator will maintain a personal 
subject identification list (subject numbers with the corresponding subject names) to enable records to be identified. 
 
A summary of all visits and procedures has been outlined below (Table 1). A more detailed description of each visit 
and accompanying procedures can be found later in the protocol (5.4 - 5.5)

5.5 Description of procedures and measurements 
5.5.1 Medical history and physical examination 
A medical history will be performed at the screening visit to record illnesses, disorders and medications. This 
information needs to be updated on all follow-up visits. 
Physical examination will be performed at the Screening visit (study visit 1) according to local procedure. During this 
visit the physician will perform a physical examination with the focus on cardiac, lung and abdominal examination. 
Any abnormal, clinical significant findings must be recorded in the SDF (Source Data Form) as well as in the eCRF 
(HybridForms®). Any changes in subsequent visits as compared to the screening visit which fulfils the criteria of an 
AE must be recorded as an AE. Any changes in concomitant illness will be recorded as changes in medical history. 
Any changes in medications will be recorded in the eCRF. 
5.5.2 ECG, echocardiography, ICD interrogation 
An ECG, echocardiography, and ICD interrogation will be performed at the screening visit. In our study, ICDs are 
interrogated both with telemedicine (home-monitoring) and during on-site ICD follow-ups. 
Patients will be offered to be included in our home-monitoring program. Currently, already 80% of patients have a 
home-monitoring device and routinely (every 4 months) transmit their data. In case of an alarm (sustained VT/VF) 
the data is transmitted automatically. In addition, all patients, regardless if they have a home-monitoring device or 
not, will be checked in the outpatient clinic on a yearly basis. 
All arrhythmic events are recorded in the patient database. For this study, the number of episodes recorded during 
the study period will be tallied up. 
All tests will be interpreted, signed and dated by the investigator before randomisation. 
5.5.3 Vital signs 
Pulse should be recorded at all visits after resting for five minutes in a sitting position. Systolic and diastolic blood 
pressure will be measured in sitting position at all visits. 
5.5.4 Body weight and height 
Weight should be measured at all visits. The same and calibrated pair of scales should preferably be used throughout 
the trial. Height will be recorded at the screening visit. BMI (body mass index) will be calculated as follows: BMI = 
weight (kg)/height2 (m2). 
5.5.5 Routine biochemistry  
Blood samples will be obtained at all visits and processed by the local laboratory using standard methods’ for routine 
tests. Patients can take their regular morning medications but are asked that they do not take any of their diabetes 
medications on the morning of their study visit. Patients should bring their regular medication along to their study 
visits to be further advised by the doctor. See table 2 below for a detailed description of blood collection at each 
visit:

5.5.6 Blood sample collection and plasma extraction for biobanking 
Blood will be collected via venous puncture into 16ml serum and 10ml EDTA vacutainers and centrifuged within 30 
min of collection. Plasma should be transferred into Eppendorf tubes and stored at -80°C locally. In regular intervals 
these samples will be shipped on dry ice to the Biobank of the Medical University of Graz, where they will be stored 
at -80°C for future biomarker analyses. Additional biomarkers will be measured in batches from these stored 
biomarker samples. 
 
5.6 Benefit-Risk Assessment 
Ertugliflozin has been studied in subjects with type 2 diabetes as monotherapy as well as in combination with DDP-
inhibitors as well as metformin. A cardiovascular safety study is ongoing(14). However, it has not been studied with 
respect to cardiac arrhythmias, yet. Other SGLT-2 inhibitors already finished the cardiovascular outcome trials(1; 15-
17) demonstrating cardiovascular safety and beneficial effects, most prominent with respect to heart failure. A class 
effect can be assumed. Moreover, first data is published, demonstrating beneficial cardiovascular effects in non-
diabetic patients with heart failure, too. As heart failure per se is a trigger for ventricular arrhythmias, every 
improvement in heart failure is likely to reduce ventricular arrhythmias, too. 

 
 
Title: 
ERASe–TRIAL 
 
Protocol No: 
Version 1.20 
 
22 December 2021 
 
 
23  
 
With respect to diabetes it can to be taken as given that the drug is not causing hypoglycaemic events per se, 
hypoglycaemia appears not to be a major issue in subjects without diabetes, that are studied in this trial as well. 
When ertugliflozin is used together with sulfonylurea or insulin, hypoglycaemia might occur and therefore 
participants will be instructed to reduce concomitant antihyperglycemic medication accordingly.  
Fungal genital infections are the most common side effect of ertugliflozin and participants will be informed about 
this and instructed on prevention measures.  
6. ADVERSE EVENTS (AE) 
An AE is any untoward medical occurrence in a patient or clinical trial subject administered a medicinal product and 
which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavourable 
and unintended sign (including an abnormal laboratory finding), symptom, including an exacerbation of a pre-existing 
condition, or disease temporally associated with the use of the trial device/procedure, whether or not considered 
related to the treatment. 
All adverse events that occur during this study will be recorded on the adverse event case report forms. 
6.1 Adverse Event description 
For the purposes of the study, AEs will be followed up according to local practice until the event has stabilised or 
resolved, or the Follow-up Visit, whichever is the sooner. AEs will be recorded throughout the study. 
6.2 Severity of Adverse Events 
Mild: Awareness of event(s) or sign(s) but easily tolerated 
Moderate: Discomfort enough to cause some interference with usual activity 
Severe: Incapacitating or causing inability to carry out usual activity 
6.3 Causality of Adverse Events 
Medical judgment should be used to determine the relationship, considering all relevant factors, including pattern 
of reaction, temporal relationship, de-challenge or re-challenge, confounding factors such as concomitant 
medication, concomitant diseases and relevant history. Assessment of causal relationship should be recorded in the 
case report forms.  
Yes: 
There is a reasonable causal relationship between the investigational product  administered and the AE.  
No: 
There is no reasonable causal relationship between the investigational product administered and the AE. 
6.4 Abnormal Laboratory Test Results 
All clinically significant abnormal laboratory test results besides creatinkinase and NT-proBNP occurring during the 
study will be recorded as adverse events.

6.5 Adverse events of Special Interest (AESIs) 
The term AESI relates to any specific AE that has been identified at the project level as being of particular concern 
for prospective safety monitoring and safety assessment within this trial, e.g. the potential for AEs based on 
knowledge from other compounds in the same class. AESIs need to be reported to the Pharmacovigilance 
Department of MSD within the same timeframe that applies to SAEs. 
Patients with AESIs need to be followed up appropriately, regardless of the origin of the laboratory data (e.g. central, 
local etc.). The Investigator should consider which, if any, concomitant therapies should not be taken during 
evaluation. Discontinued treatments can be reintroduced per Investigator discretion. 
The following are considered as AESIs: 
6.5.1 Hepatic injury 
A hepatic injury is defined by the following alterations of hepatic laboratory parameters after randomisation:  
- 
an elevation of AST and/or ALT ≥ 3 fold ULN combined with an elevation of total bilirubin ≥ 2 fold ULN 
measured in the same blood sample 
- 
an isolated elevation of ALT and/or AST ≥ 5 fold ULN 
 
These laboratory findings constitute a hepatic injury alert and the patients showing these abnormalities need to be 
followed up according to medical judgement.  
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, unexplained coagulopathy, right 
upper quadrant abdominal pain, etc.) without laboratory results (ALT, AST, total bilirubin) available, the Investigator 
should make sure these parameters are analysed, if necessary in an unscheduled blood test. 
6.5.2 Decreased renal function 
Decreased renal function is defined by a creatinine value showing a ≥ 2 fold increase from baseline and is above the 
ULN. 
For the AESI “decreased renal function” the Investigator shall collect an unscheduled laboratory sample for creatinine 
as soon as possible and initiate follow-up laboratory tests of creatinine according to medical judgement. 
6.5.3 Metabolic acidosis, ketoacidosis and diabetic ketoacidosis (DKA) 
In case of metabolic acidosis, ketoacidosis and DKA further investigations should be done according to the medical 
judgment and the clinical course until a diagnosis is made and/or the patient is recovered. 
DKA is defined by the diagnostic criteria in the table below, and as defined by the American Diabetes Association 
(ADA). 
Investigators should note that not all criteria in the table below need to apply for the diagnosis of DKA, and clinical 
judgment should also be taken into consideration. Due to its mechanism of action, ertugliflozin may potentially 
modify the clinical presentation of DKA which may occur at lower plasma glucose levels than stated in the table 
below.

6.5.4 Events involving lower limb amputation 
This definition includes amputation (i.e. resection of a limb through a bone), disarticulation (i.e. resection of a limb 
through a joint) and auto-amputations (i.e. spontaneous separation of non-viable portion of the lower limb). 
Not included in this definition are debridement (removal of callus or dead tissue), procedures on a stump (like stump 
revision, drainage of an abscess, wound revision etc.) and other procedures (e.g., nail resection or removal) without 
a concomitant resection of a limb (amputation or disarticulation). 
Each lower limb amputation, disarticulation, or auto-amputation should be reported separately. The SAE report 
should include the date of the procedure, the level of amputation or disarticulation, the medical condition(s) leading 
to the procedure and if the patient had some of the known risk factor(s) for lower limb amputation. 
 
6.6 Serious Adverse Events (SAE) 
An SAE is defined as any event that 
- 
Results in death; 
- 
Is immediately life-threatening*; 
- 
Requires hospitalisation or prolongation of existing inpatient’s hospitalisation**  
- 
Results in persistent or significant disability or incapacity; 
- 
Is a congenital abnormality or birth defect; 
* “Life-threatening” in the definition of “serious” 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. 
** “Hospitalisation” means any unexpected admission to a hospital department. It does not usually apply to scheduled admissions that were 
planned before study inclusion or visits to casualty (without admission). 
 

 
 
Title: 
ERASe–TRIAL 
 
Protocol No: 
Version 1.20 
 
22 December 2021 
 
 
26  
 
Medical judgement should be exercised in deciding whether an adverse event/reaction is serious in other situations. 
Important adverse events/reactions that are not immediately life-threatening, or do not result in death or 
hospitalisation but may jeopardise a subject, or may require intervention to prevent one of the other outcomes listed 
in the definition above should also be considered serious. 
 
Patients may be hospitalised for administrative or social reasons during the study (e.g. days on which infusion takes 
place, long distance from home to site,). These and other hospitalisations planned at the beginning of the study do 
not need to be reported as a SAE in case they have been reported at screening visit in the source data and have been 
performed as planned. 
 
Worsening of the underlying disease or other pre-existing conditions 
Worsening of the underlying disease or of other pre-existing conditions will be recorded as an (S)AE in the (e)CRF. 
 
Changes in vital signs, ECG, physical examination, and laboratory test results 
Changes in vital signs, ECG, physical examination and laboratory test results will be recorded as an (S)AE in the (e)CRF,   
if they are judged clinically relevant by the investigator. 
 
6.6.1 Reporting of SAEs 
The study sites shall report (i.e., from signing the informed consent onwards through the trial defined follow-up 
period) all SAEs and non-serious AEs which are relevant for a reported SAE and Adverse Events of Special Interest 
(AESI) by fax or other secure method using the FDA Safety Information Form to the MSD Unique Entry Point 
immediately (within twenty four (24) hours or next business day whichever is shorter) 
Merck Sharp & Dohme Ges.m.b.H 
The ICON Vienna 
Wiedner Gürtel 9-13 
Fax: 0800 809 802 
The sponsor will report the SAE to the ethics committee and the local authorities. 
A suspected unexpected serious adverse reaction (SUSAR) is designated as such according to Guideline 2001/20/EG. 
A serious adverse reaction is deemed unexpected when it is not listed in the corresponding basic document 
(Summary of Product Characteristics, IB, IMPD). 
7. STATISTICAL ANALYSES 
The sample size calculations and the primary statistical method are based on the primary endpoint, which is the 
number of VT/VF episodes from randomization to week 52. The primary objective is to compare the rate of VT/VF 
episodes across the two experimental arms. The number of VT/VF episodes within 52 weeks can be considered as a 
discrete variable with relatively few possible values (0, 1, 2, 3 …) per patient. This fact prevent us from using the most 
common statistical methods in clinical trials that assume normality, such as Student’s t-test, linear regression or

analysis of variance.  We, instead, will use the negative binomial regression model, which is most appropriate in the 
case of recurrent events (the current situation), allows investigation of the treatment effect and confounding 
variables, and adjusts for variable follow-up times by using time at risk as the offset. For more details on the 
arguments to use the negative binomial models in this kind of research, please see: (18). Furthermore, the negative 
binomial will be used instead of the Poisson distribution (also used for modelling count data) due to expected over-
dispersion in the data.    
7.1 Sample size and power considerations 
Previous data showed that VT/VF episodes are decrease by two thirds within 6 months after initiation of 
sacubitril/valsartan in ICD±CRT patients (10). sVT/VF Episodes declined by 62.5% whereas nsVTs rate dropped by 
~70%.  Based on comparable effects on heart failure morbidity with either SGLT-2 inhibition or sacubitril/valsartan 
treatment we expect a profound reduction in sVT/VF in the treatment arm. Since data of the large SGLT2 outcome 
trials which did not focus on arrhythmias and their detection but only counted cases of sudden cardiac death have a 
signal of smaller effects we calculate with a decrease in the event rate of 30%. Moreover, the retrospective analysis 
by Martens et al provides a rather low event rate in their population. However, as pointed out in the Introduction 
other prospective randomized trials have considerably higher event rates. The sample size calculation is based on 
the mathematical formula provided by Zhu and Lakkis for comparing event rates of two negative binomial 
distributions (19). We used the function power.nb.test of the package MKmisc in R that implements the results of 
the paper cited above. According to that formula, the parameters needed to calculate the sample size are: The 
expected yearly rate of VT/VF episodes in the control group (r0),  The minimal clinical relevant effect (RR) defined 
here as the ratio of expected VT/VF episodes rates (RR = expected rate in treated/expected rate in control = r1/r0), 
the average follow-up or treatment duration (duration), the negative binomial dispersion parameter (k), the Type I 
error probability (α) and the power (1 - β).  To detect a 30% reduction in VT/VF episodes rate in the ertugliflozin 
group as compared to the placebo group (i.e. using RR =  0.70), with a power of 80% and an alpha-level of 0.05%, a 
sample size of 191  patients in each group is needed. In this sample size calculation, we assumed the dispersion 
parameter k to be 1.0, the expected yearly rate of VT/VF episodes in the control group (i.e. r0) to be 1.0 and an 
average follow-up of 11.4 months. To account for a dropout rate of about 5% in each group, we will need of 402 
patients in each arm. 
Out of the > 1000 patients with ICD±CRT being seen at our out-patients clinic >50% have experienced episodes of 
non-sustained VT within the last 12 months. In order to enrich the study population with higher risk patients at least 
on additional inclusion criterion has to be met (either nt-proBNP > 500pg/mL or LV-EF < 35% or hospitalization for 
heart failure within the last 12 months or >100nsVTs or > 1sVT/VF episode within the last 12 months). 
About 5-10% of our patients are currently treated with ARNI. Expecting similar numbers in the other participating 
centers we feel confident to recruit patients for this trial within 18 months. Moreover, the recent DAPA-HF trial with 
11% of patients on ARNI therapy revealed an unaltered benefit of SGLT-2 inhibition in these patients(2).

Taking into account that compared to the Martens-trial the expected reduction in the applied study is much lower, 
the observation period twice as long and the populations risk is enriched due to the inclusion criteria the calculation 
can be rated conservative. 
7.2 Data analysis 
Intention-to-treat (ITT) analyses will be applied as the primary analysis. Analysis of the primary endpoint is 
comparison of the number of sVT/VF episodes between treatment groups from randomization to week 52. The 
primary endpoint will be analysed using analysis of covariance (ANCOVA), with treatment as a fixed factor, the 
baseline number of sVT/VF episodes as a covariate and with adjustment for history of T2D and eGFR and site of 
randomization. 
Normally distributed variables will be presented as mean ± standard deviation (SD) and skewed distributed variables 
as median and interquartile range [IQR]. Comparisons between treatment and placebo group will be performed by 
an unpaired two sample t-test, Mann–Whitney test, or χ2 test as appropriate. 
A two-tailed p-value ≤0.05 will be considered statistically significant. A detailed statistical analysis plan including pre-
specified subgroup analyses will be finalized ahead of database lock. 
8. DATA MANAGEMENT 
Data Management is the responsibility of the Medical University of Graz, Department of Cardiology and the study 
Monitor. The subject and the biological material obtained from the subject will be identified by subject number, trial 
site and trial identification number. Appropriate measures such as encryption or deletion will be enforced to protect 
the identity of human subjects in all presentations and publications as required by local/regional and national 
requirements. 
This study will capture and process data using an electronic Case Report Form. . Data and reports will be extracted 
from the database throughout the study to monitor progress and training will be provided to all study staff on use of 
the database. The study will be monitored by qualified employees of the research group of cardiovascular 
Diabetology based on a specific monitoring plan.  
9. TREATMENT 
9.1 Study medication 
Ertugliflozin is a sodium-glucose cotransporter 2 (SGLT2)-inhibitor. It works by increasing the amount of sugar that 
leaves the body in the urine. The study dose is 5mg once daily in the morning, taken with or without food. Each tablet 
contains 5mg Ertugliflozin or Placebo. The pharmaceutical form is a 6.4 x 6.6 mm large triangular tablet debossed 
„701“ on one side Ertugliflozin has minor influence on the ability to drive and use machines. Patients should be 
advised to take precautions to avoid hypoglycaemia while driving and using machines, in particular when Ertugliflozin 
is used in combination with a sulfonylurea and/or insulin. Pharmacy (Anstaltsapotheke) at the University Hospital of 
Graz, Austria will pack the medication as 52 weeks supplies for study participants and label study medication 
according to current regulatory requirements.

10.6 Subject Confidentiality 
The investigator must ensure that the subject’s privacy is maintained. On the CRF or other documents submitted to 
the Sponsors, subjects will be identified by a subject ID number only. Documents that are not submitted to the 
Sponsor (e.g., signed informed consent form) should be kept in a strictly confidential file by the investigator. The 
investigator shall permit direct access to subjects’ records and source document for the purposes of monitoring, 
auditing, or inspection by the Sponsor, authorised representatives of the Sponsor, Regulatory Authorities and Ethic 
Committees. 
10.7 End of Trial 
The trial will end after the last subject has completed the follow-up telephone assessment (Study visit 3). All patients 
will be reviewed by a clinician at their last study visit in order to arrange return to appropriate routine clinical care 
pathways. 
10.8 Study Documentation and Data Storage 
The investigator must retain essential documents until notified by the Sponsor, and at least for 15 years after study 
completion, as per the Sponsor’s requirements. Subject files and other source data (including copies of protocols, 
CRFs, original reports of test results, correspondence, records of informed consent, and other documents pertaining 
to the conduct of the study) must be kept for the maximum period of time permitted by the institution. Documents 
should be stored in such a way that they can be accessed/data retrieved at a later date, either in paper or 
electronically. Consideration should be given to security and environmental risks. 
No study document will be destroyed without prior written agreement between the Sponsor and the investigator.  
11. ADMINISTRATIVE MATTERS

11.2 Language 
CRFs will be in German. Generic names for concomitant medications should be recorded in the CRF wherever 
possible. All written material to be used by subjects must use vocabulary that is clearly understood, and be in the 
language appropriate for the study site. 
11.3 Data Collection 
All data collected will be documented in the source documents and eCRF (HybridForms®). 
11.4 Electronic Recording of data 
This study will capture and process data using HybridForms® (electronic data capture) which will be built by Kapsch 
Business Com AG, Graz, Austria. HybridForms® is a fully validated high quality electronic data capture system, which 
has a full audit trail and controlled level of access. Data and reports will be extracted from the database throughout 
the study to monitor progress and training will be provided to all study staff on use of the database. The Investigator 
must ensure that the data is recorded in the eCRFs as soon as possible after the visit preferably within 7 working 
days. 
11.5 Study Management Structure 
11.5.1 Trial Steering Committee (TSC) 
A Trial Steering committee (TSC) comprised by all principal investigators and chaired be the Chief investigator will be 
responsible for overseeing the progress of the trial. A TSC Charter will be devised to list the roles and responsibilities 
of the TSC members. TSC will be convened at least biannually either in person or by teleconference. 
11.6 Monitoring 
A monitoring plan will be devised based on risk analysis and described in detail in the monitoring manual. During the 
course of the trial the Monitor will visit the trial sites to ensure that the protocol is adhered to, that all issues have 
been recorded and to perform source data verification. The study will be monitored periodically by a Clinical Trial 
Monitor responsible for this study. 
Initiation visits will be completed at all trial centres prior to the recruitment of participants, and will consist of review 
of protocol and trial documents, training with respect to trial procedures (informed consent, SAE reporting, inclusion 
and exclusion criteria), review of recruitment strategy, review of site facilities and equipment, review of GCP 
principles, essential document receipt, collection and filing, and archiving and inspection. Copies of the trial specific 
procedure manuals and related documents will be given to the investigators. The approved version of the protocol 
should be followed at all times, and any significant protocol deviations will be documented in a Protocol Deviation 
Form and any significant deviations will be recorded on a Protocol Violation Form submitted to the study 
coordination centre and Sponsor as soon as possible. The investigators will allow the monitors to: 
- 
inspect the site, the facilities, device management and materials used for the trial 
- 
meet all members of the team involved in the trial, and ensure all staff working on the trial are experienced 
and appropriately trained, and have access to review all of the documents relevant to the trial 
- 
have access to the electronic case record forms and source data

- 
discuss with the investigator and site staff trial progress and any issues on a regular basis 
The monitor will ensure that: 
- 
A percentage of records will be inspected for confirmation of existence, eligibility based on the results of 
the Risk Assessment 
- 
100 % of consent forms will be reviewed along with all SAE’s. 
- 
there is adherence to the protocol, including consistency with inclusion/exclusion criteria 
- 
there is GCP and regulatory compliance 
- 
trial documentation is complete and up to date (e.g. correct versions of documents being used, source data 
captured) and relevant documents are collected for the Trial Master File (TMF) 
- 
the monitored eCRFs have been completed correctly and accurately, and all entries correspond to data 
captured in source documents 
The Monitor must be given direct access to the source documents (original documents, data and records). Direct 
access includes permission to examine, analyse, verify and reproduce and record reports that are important to 
evaluation of the clinical trial. 
All information dealt with during such visits will be treated as strictly confidential. At the end of the trial, close out 
visits will be performed by the monitor after the final participant visit has been completed and prior to database lock. 
During this visit the monitor will verify that all trial close out activities are completed – all queries resolved, missing 
data completed, monitoring completed, archiving arrangements in place, ISF completed and TMF documents 
collected, and end of trial notification. Each investigator will also be notified that an audit or inspection may be 
carried out - by the sponsor, sponsor's representatives or the host institution, or regulatory authorities - at any time, 
before, during or after the end of the trial. The investigator must allow the representatives of the audit or inspection 
team: 
- 
to inspect the site, facilities and material used for the trial, 
- 
to meet all members of his/her team involved in the trial, 
- 
to have direct access to trial data and source documents, to consult all of the documents relevant to the 
trial. If an Investigator is informed of an impending audit or inspection, the trial coordination centre should 
be notified immediately. 
 
11.7 Disclosure of data and publication 
Information concerning the study, patent applications, processes, scientific data or other pertinent information is 
confidential and remains the property of the Sponsor. The investigator may use this information for the purposes of 
the study only. Verbal or written discussion of results prior to study completion and full reporting should only be 
undertaken with written consent from the Sponsor. Therefore all information obtained as a result of the study will 
be regarded as CONFIDENTIAL, at least until appropriate analysis and review by the investigators is completed. 
Permission from the Trial Steering Committee is necessary prior to disclosing any information relative to this study 
outside of the Steering Committee.
