5.1.1 Endpoint reporting overview
5.1.3 Potential renal endpoints
Removing the requirement of adjudicating potential endpoints 
related to estimated glomerular filtration rate (eGFR) decline.  
The rational for this change is that the endpoint criteria are not 
justifying adjudication of these events. 
6.3 Recording of adverse events
6.3.2.2 Renal events
Clarification added based on feedback that the criteria was too 
vague, regarding what is considered an adverse event (AE) of 
interest in terms renal events. 
6.3 Recording of adverse events
6.3.7 Adverse events based on 
examination and tests
Limiting the recording of AEs to not include potential renal 
endpoints that are based on examination and tests, i.e., 
laboratory results only, unless fulfilling the serious adverse 
event (SAE) criteria or Discontinuation of investigational 
product due to adverse event (DAE) criteria. The reason not to 
record these endpoints related to laboratory findings is that 
protocol mandated laboratory values will be systematically 
analysed.  
6.4.1 Reporting of SAEs 
considered to be potential 
endpoints
Limiting the event types that are being withheld from reporting 
to health authorities to include only heart failure endpoints and 
fatal AE. i.e., AEs related to renal endpoints will not be 
withheld. The rationale for this limitation is to simplify the SAE 
reporting and to minimise the risk for withholding renal AEs of 
interest, which should be reported, and which could be confused 
for being a primary or secondary renal endpoint. 
6.9 Medication Error
Adding information about Medication Error definition and 
reporting.
7.7.2 Prohibited medication
Clarifying that open label treatment with Sodium glucose co-
transporter 2 (SGLT2) in combination with IP is not allowed and 
that open label treatment with SGLT2 inhibitors should be 
avoided during the course of the study, i.e., clarifying that usage 
of open label treatment with SGLT2 inhibitors are not prohibited 
if the patient is not taking study medication but should be 
avoided. The rational for this update is to clarify that it is 
administration of an open label SGLT2 inhibition in 
combination with IP that is a protocol deviation and not if the 
patient is off IP. 
7.7.3 Recording of concomitant 
medication
Including cardiovascular (CV) medications to be recorded in 
detail in the electronic case report form (eCRF) during the 
course of the study.

Objectives
Primary Objective:
Outcome Measure:
To determine if dapagliflozin is superior to 
placebo in reducing the incidence of the primary 
composite endpoint of ≥50% sustained decline in 
estimated glomerular filtration rate (eGFR), 
reaching end stage renal disease (ESRD), CV or 
renal death when added to current background 
therapy in patients with eGFR ≥25 and 
≤75 mL/min/1.73m2 and albuminuria (urine 
albumin creatinine ratio [UACR] ≥200 and 
≤5000 mg/g).

or hospitalisation for heart failure.  
Time to the first occurrence of either of the 
components of this composite: 
1.
CV death

Safety Objective:
Outcome Measure:
To evaluate the safety and tolerability of 
dapagliflozin in this patient population.  
1.
Serious adverse event (SAE)
2.
Discontinuation of investigational 
product (IP) due to adverse event 
(DAE)s
3.
Changes in clinical 
chemistry/haematology parameters
4.
Adverse events (AEs) of interest 
(volume depletion, renal events, major 
hypoglycaemic events, fractures, 
diabetic ketoacidosis (DKA), Adverse 
events (AEs) leading to amputation 
and AEs leading to a risk for lower 
limb amputations [“preceding 
events”])
Target patient population
The target population will have CKD (eGFR ≥25 and ≤75 mL/min/1.73m2) with albuminuria 
(urine albumin creatinine ratio [UACR] ≥200 and ≤5000 mg/g) with or without type 2 
diabetes (T2D).  However, patients with known polycystic kidney disease, glomerulonephritis 
with flares (lupus or anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitis) or 
ongoing active renal inflammation will be excluded.
Duration of treatment
This study is event-driven.  The anticipated duration of the study is approximately 45 months 
with an estimated mean treatment period for a patient of 33 months.  The study closure 
procedures will be initiated when the predetermined number of primary endpoints are 
predicted to have occurred (n=681), i.e., the study end date (SED).  The study duration may be 
changed if the event rate or randomisation rate is different than anticipated.  The study may be 
terminated early if either a clear beneficial or harmful effect of the study treatment is detected 
during the Data Monitoring Committee (DMC) review.  
Investigational product (IP), dosage and mode of administration
Patients will be randomised 1:1 to either dapagliflozin 10 mg or placebo.  Every attempt 
should be made to maintain patients on dapagliflozin 10 mg or matching placebo during the 
course of the study.  In addition to the preferred 10 mg dose, the 5 mg dose of dapagliflozin

can be used in the study when clinically indicated.  If the dose has been decreased to 5 mg, the 
dose should be increased back to dapagliflozin 10 mg or matching placebo as soon as, in the 
opinion of the investigator, the patient’s condition is stable.
Statistical methods
The primary objective of the study is to determine the superiority of dapagliflozin versus 
placebo in reducing the incidence of the primary composite endpoint.  Assuming a true hazard 
ratio of 0.78 between dapagliflozin and placebo, using a one-sided alpha of 2.5%, 681 primary 
endpoint events will provide a statistical power of 90% for the test of the primary composite 
endpoint.  This is based on an overall 1:1 allocation between dapagliflozin and placebo.  The 
study is event-driven.
With an annual event rate of 7.5% in the placebo treatment group, 4000 patients are estimated 
to provide the required number of primary events, based on an anticipated recruitment period 
of 24 months and an average follow-up period of approximately 33 months.
All patients who have been randomised to study treatment will be included in the full analysis 
set (FAS) irrespective of their protocol adherence and continued participation in the study.  
The primary variable is the time to first event included in the primary composite endpoint.  
The primary analysis will be based on the intention to treat (ITT) principle using the FAS.  In 
the analysis of the primary composite endpoint, dapagliflozin versus placebo will be compared 
using a Cox proportional hazards model with a factor for treatment group, stratified by 
randomisation stratification factors (T2D, UACR), and adjusting for eGFR.  
A closed testing procedure including a pre-specified hierarchical ordering of the primary and 
secondary endpoints will be utilized.  No multiplicity control is placed on the exploratory 
endpoints.

INTRODUCTION
1.1
Background and rationale for conducting this study
Chronic kidney disease (CKD) affects approximately 10% of the adult population worldwide 
(Eckart et al 2013).  The most common causes of CKD are diabetes, hypertension and chronic 
glomerulonephritis.  Treatment for CKD encompasses angiotensin converting enzyme inhibitor 
(ACE-I) and angiotensin II receptor blockers (ARBs), lipid and blood pressure (BP) control as 
well as a tight glucose control in diabetic patients.  
Dapagliflozin (Forxiga™/Farxiga™) is a highly selective and reversible inhibitor of the sodium 
glucose co-transporter 2 (SGLT2), the major transporter responsible for glucose reabsorption in 
the kidney.  Dapagliflozin’s mechanism of action results in a direct and insulin independent 
elimination of glucose by the kidneys, which results in reduced blood glucose levels in 
type 2 diabetes (T2D) patients.  In addition, dapagliflozin has a mild diuretic and natriuretic 
effect.  The persistent loss of glucose with associated calories in the urine, results in a 
consistent and maintained reduction of the total body weight, predominantly a result of a 
reduction in fat mass including both visceral and subcutaneous adipose tissue.  Moreover, 
dapagliflozin has also been shown to reduce BP and albuminuria, two essential prognostic risk 
factors for progression of CKD.  
There is a growing body of evidence indicating that SGLT2 inhibition is nephroprotective.  
This effect is thought to be achieved partly by mechanisms independent of blood glucose 
reductions (Rajasekeran et al 2016, Heerspink at al 2016b), such as reduced intra-glomerular 
pressure through an enhanced tubuloglomerular feedback mechanism (De Nicola et al 2014, 
Thomas 2014), reduced glucose and sodium transport over the proximal tubule cells (Komala et 
al 2013, Pollock et al 1991), increased natriuresis (Heerspink et al 2013) and reduced systemic 
BP (Baker et al 2015, Sjöström et al 2015a).  Interestingly, there is a theoretical rationale for an 
improved oxygen availability in the impaired kidney during dapagliflozin treatment.  This 
could potentially be achieved via two mechanisms.  Firstly, an improved oxygen delivery due 
to a small but consistently observed haemo-concentration and secondly through a reduced renal 
oxygen consumption due to a reduced energy requirement from the potassium sodium pump 
situated on the basal-lateral membrane striving to retain the sodium gradient over the tubular 
cells (Gilbert RE 2016, Korner et al 1994).  Finally, there are emerging theories around 
metabolic benefits connected to a mild ketosis induced by SGLT2 inhibition (Mudaliar et al 
2016).
Notably, the total amount of glucose excreted in the urine following dapagliflozin 
administration, declines with decreasing kidney function and clinically important reduction in 
glycated haemoglobin (HbA1c) has not been demonstrated in T2D patients with estimated 
glomerular filtration rate (eGFR) <45 ml/min (Kohan et al 2014).  However, similar reductions 
of non-glycaemic variables such as BP, body weight and albuminuria have been observed with 


Clinical Study Protocol

dapagliflozin (Kohan et al 2014) and other SGLT2 inhibitors (Barnett et al 2014, Yale et al 
2013) in patients with impaired renal function as in patients with normal renal function.  
Furthermore, post-hoc analyses of data from the dapagliflozin phase II and phase III 
programme have shown in T2D patients with moderate renal impairment on renin-angiotensin-
aldosterone system (RAAS) blockade a reduction of around 40% in albuminuria and 
stabilization of eGFR decline for up to one year (Sjöström et al 2015b) and two years  (Fioretto 
et al 2016).  The EMPA-REG outcome trial, examining the cardiovascular (CV) effect of 
empagliflozin in T2D patients has further indicated beneficial renal effects of SGLT2 
inhibition.  After an initial drop in eGFR, kidney function was stable over time while a 
progressive decrease in eGFR was seen in the placebo group.  The trial also suggested 
substantial risk reductions for new onset of macroalbuminuria, doubling of serum creatinine 
and initiation of dialysis treatment (Wanner et al 2016).  
Nephroprotective effects not related to glucose excretion, rationale for use in non-T2D
As indicated above many of the effects from SGLT2 inhibition thought to contribute to a 
nephroprotective effect seem to be largely unrelated to glucose control per se.  Accordingly, 
regression analyses on data from the dapagliflozin phase III program indicate that the 
albuminuria lowering effect is not dependent on the glucose lowering actions seen during 
SGLT2 inhibition (Heerspink et al 2016, Fioretto et al 2016).  Furthermore, pooled data from 
the phase III program does not indicate a reduced effect on volume constriction (as measured 
by changes in haematocrit), systolic BP, pulse pressure, albuminuria and body weight in 
subjects with low glucose excretion due to renal impairment as compared with subjects 
excreting larger amounts of glucose in the urine (Sjöström et al 2016, EASD 2016).
Data on the effect of SGLT2 inhibition in patients without diabetes is limited.  However, 
dapagliflozin has safely been administered in healthy volunteers over a broad dose range (up to 
500 mg given as single dose) (Kasichayanula et al 2014).  Dapagliflozin effectively inhibited 
SGLT2 also in healthy volunteers without any observed events of hypoglycaemia.  
Furthermore, a clinical trial with canagliflozin, showed clinically relevant BP and weight 
reductions in obese non-diabetic patients without an increased incidence of hypoglycaemia 
(Bays et al 2013).  
Overall, the available data strongly indicate that non-diabetic CKD patients would also benefit 
from SGLT2 inhibition induced changes in variables important for nephroprotection.  As a 
consequence, this study will include CKD patients with and without T2D.
1.2
Rationale for study design, doses and control groups
1.2.1
Rationale for study design and study population
This is a randomised, double-blind, parallel-group study.  Randomisation and double blinding 
will minimize potential bias.  Parallel group design was chosen because a crossover study 
cannot assess major renal outcome events.  The study will be multicentre in numerous 
geographic regions to provide a wide applicability of results.

The study population chosen for this study is a broad population of patients with impaired 
kidney function.  Patients with CKD are at high risk of CV events, terminal renal failure and 
death (Go et al 2004).  Albuminuria adds to this risk, hence, the target population will have 
CKD (eGFR ≥25 and ≤75 mL/min/1.73m2) with albuminuria (urine albumin creatinine ratio 
[UACR] ≥200 and ≤5000 mg/g).  However, patients with known polycystic kidney disease, 
glomerulonephritis with flares (lupus or anti-neutrophil cytoplasmic antibodies [ANCA] 
associated vasculitis) or ongoing active renal inflammation will be excluded.
There is scientific rationale for beneficial effects of SGLT2 inhibition also in patients with 
CKD but without diabetes.  Patients with CKD have similar clinical picture with increased 
intra-glomerular pressure, hypertension, proteinuria and fluid/sodium overload regardless of 
underlying disease.  SGLT2 inhibition can improve on all these abnormalities through 
metabolic-independent mechanisms.  Moreover, the reduction on CV and renal events with 
empagliflozin cannot be explained by the glucose lowering effect alone (Rajasekeran et al 
2016, Mudaliar et al 2016, Gilbert RE 2016).
1.2.2
Rationale for primary outcome measure
The primary outcome measure is based on the requirements as outlined in the European 
Medicines Agency (EMA)’s draft guideline, which states that a composite endpoint of ≥50% 
sustained decline in eGFR, end stage renal disease (ESRD) and renal death (death due to ESRD 
when dialysis is not given) are acceptable outcome measures (EMA 2016).  This endpoint has 
also been used in a number of previous outcome studies.  
CV mortality is added as a component of the composite endpoint since CV mortality in the 
population being studied is high and the risk for CV death correlates with the risk of developing 
ESRD.  Thus, CV mortality is a competitive risk component and dapagliflozin is expected to 
have a beneficial effect on both CV death and renal outcome (Wanner et al 2016).
1.2.3
Rationale for secondary outcome measure 
It is of importance to separately look at the effect on composite renal endpoints and the 
composite heart failure endpoints (hospitalisation for heart failure and CV death).  Heart failure 
is particularly common in patients with CKD.  SGLT2 inhibition has previously shown to have 
beneficial effects on heart failure outcomes in patients with T2D and established CV disease 
(Zinman et al 2015).  All-cause mortality will be assessed as a secondary endpoint because it is 
important to evaluate the effect of dapagliflozin on non-CV, as well as CV, mortality and hence 
overall mortality.
1.2.4
Rationale for dose selection
The marketed dose, 10 mg, of dapagliflozin has been demonstrated to be well tolerated and 
effective for the treatment of T2D and post hoc analyses in patients with CKD and albuminuria 
have shown that this dose effectively reduces renal surrogate markers, i.e., BP and albuminuria, 
independent of the glucose lowering effect.  In a dedicated CKD 3 study (eGFR 30 to 60 
mL/min/1.73m2) this dose was found to be well tolerated (Kohan et al 2014).  From a 
pharmacokinetics (PK) and pharmacodynamics perspective, dapagliflozin 10 mg is appropriate 


Clinical Study Protocol

Study Code D169AC00001
Version 4.0

for use in patients with renal impairment.  The marketed 5 mg dose of dapagliflozin may be 
used in the study, but it is expected to provide less inhibition of SGLT2 and thus exert less 
pharmacodynamics effects (for details on when 5 mg or matching placebo can be used, see 
Section 3.9.1).
1.3
Benefit/risk and ethical assessment 
Dapagliflozin has global market approval and based on global cumulative sale figures up to
March 2016 it is estimated that dapagliflozin has been administered for >1 000 000 patient 
years.
1.3.1
Potential risks
The potential risks of treatment with dapagliflozin are described in the Investigator’s Brochure 
(IB).  Additional considerations relevant for the target population are described below.  
Dapagliflozin has not been shown to induce hypoglycaemia in non-diabetes patients.  In 
clinical pharmacology studies, healthy subjects have been treated with single oral doses up to 
500 mg and multiple oral doses of 100 mg up to 14 days without any hypoglycaemic event.
Events related to volume depletion (including reports of dehydration, hypovolemia, or 
hypotension) and events related to changes in renal function have been thoroughly evaluated in 
the dapagliflozin phase III program.  In a large pool consisting of 21 active- and placebo-
controlled studies, serious adverse events (SAEs) of volume depletion were infrequently 
reported and the proportion was even lower for subjects treated with dapagliflozin than control 
(0.1% versus 0.2%).  SAEs of renal impairment/failure were also rarely reported and balanced 
between treatment groups in the clinical trial program.  In total, 9 (0.2%) SAEs were reported 
in the dapagliflozin group and 5 (0.1%) SAEs in the control group.  
Although the phase III data in patients with CKD 3 show an increased frequency of overall 
renal events in patients treated with dapagliflozin as compared with placebo, most of these 
events have been related to laboratory detected transient increases in creatinine.  
In an analysis using pooled data on a subset of patients with CKD 3, micro or macro 
albuminuria and treatment with ACE-I or ARB there was no meaningful difference between 
dapagliflozin and placebo in terms of SAEs of renal impairment/failure or SAEs of volume 
depletion (Sjöström et al 2015b).  
Similarly, in a recent analysis of patients with pre-existing heart failure (HF) using pooled data 
from previous dapagliflozin studies (Kosiborod et al 2016), the rate of hypovolemic events was 
similar between patients treated with dapagliflozin and patients treated with placebo.  
Loop-diuretics are widely used in the target patient population and are also allowed in this 
study.  In the dapagliflozin phase III program, patients using loop diuretics were more likely to 
have an event related to volume depletion regardless of whether they were treated with 
dapagliflozin or placebo.  A pooled analysis of the short-term treatment periods showed 
6 (2.5%) subjects with events in patients on dapagliflozin 10 mg and 4 (1.5%) in patients on

placebo.  When including the long-term extension periods of the phase III trials in the analysis, 
the corresponding values were 7 (3.0%) versus 7 (2.7%) for dapagliflozin and placebo, 
respectively.  
Furthermore, other post hoc safety analyses of importance to the current target population have 
not identified any indication of an increased risk of marked abnormalities in potassium levels 
(≥6 mmol/L) in either patients with CKD 3 and ACE-I/ARB treatment (Sjöström et al 2015b)
or in patients on concomitant treatment with potassium sparing agents (Kosiborod et al 2016). 
1.3.1.1
Protection against risks
This study has been designed with appropriate measures in place to monitor and minimize any 
potential health risks to participating patients.  In order to ensure the safety of all patients 
participating in AstraZeneca (AZ) sponsored studies, reviews of all safety information from all 
ongoing clinical dapagliflozin studies are conducted as they become available.  In addition, an 
independent Data Monitoring Committee (DMC) will be responsible for safeguarding the 
interests of the patients by reviewing safety data throughout the study.
1.3.2
Potential benefits to patients
In this study, the dose of dapagliflozin 10 mg was chosen based on previous clinical 
experience.  Dapagliflozin is believed to be nephroprotective through non-glycaemic 
mechanisms and the hypothesis is that patients treated with dapagliflozin will have delayed 
progression of CKD and reduction in CV mortality.  Dapagliflozin has been shown to reduce 
UACR, HbA1c, BP and body weight in patients with T2D.  
Patients, irrespective of treatment, in clinical studies may receive greater medical care/attention 
than in ordinary clinical practice.
1.3.3
Conclusion
At the time of writing this clinical study protocol, no available SGLT2 inhibitors are indicated 
for treatment of CKD in patients with and without T2D.  Considering the non-clinical and 
clinical experience with dapagliflozin and the precautions included in the study protocol, 
participation in this study should present a minimal and thus acceptable risk to patients who 
meet the inclusion/exclusion criteria and consent to take part in the study.
1.4
Study design 
This is an international, multicentre, event-driven, randomised, double-blind, parallel-group, 
placebo-controlled study, evaluating the effect of dapagliflozin 10 mg versus placebo, given 
once daily in addition to standard of care, to prevent the progression of CKD or CV/renal death.  
It is estimated that approximately 10 000 patients at approximately 450 study sites in 
approximately 20 countries will be enrolled to reach the target of approximately 
4000 randomised patients.

10.
Active malignancy requiring treatment at the time of visit 1 (with the exception of 
successfully treated basal cell or treated squamous cell carcinoma).  
11.
Hepatic impairment (aspartate transaminase [AST] or alanine transaminase [ALT] 
>3x the upper limit of normal [ULN]; or total bilirubin >2x ULN at time of 
enrolment).  An isolated increase in bilirubin in patients with known Gilbert’s 
syndrome is not a reason for exclusion.
12.
Known blood-borne diseases such as specified in Appendix B (category A and B).
13.
Women of child-bearing potential (i.e., those who are not chemically or surgically 
sterilised or who are not post-menopausal) who are not willing to use a medically 
accepted method of contraception that is considered reliable in the judgment of the 
investigator, from the time of signing the informed consent throughout the study 
and 4 weeks thereafter, OR women who have a positive pregnancy test at enrolment 
or randomisation OR women who are breast-feeding.
14.
Involvement in the planning and/or conduct of the study (applies to both AZ 
personnel and/or site personnel).
15.
Previous randomisation in the present study.
16.
Participation in another clinical study with an IP during the last month prior to 
enrolment.
17.
Inability of the patient, in the opinion of the investigator, to understand and/or 
comply with IP, procedures and/or follow-up OR any conditions that, in the opinion 
of the investigator, may render the patient unable to complete the study.  

Patients who cannot complete the patient reported outcome (PRO) 
assessments can still participate in the study (see Section 5.1.8.3 for 
details regarding the patient exclusion from the PRO assessments during 
certain circumstances).  
Procedures for withdrawal of incorrectly enrolled patients see Section 3.4.
3.3
Patient enrolment and randomisation
Investigator(s) should keep a record, the patient screening log, of patients who entered pre-
study screening.  
The Investigator(s) will:
1.
Obtain signed informed consent from the patient or their guardian/legal 
representative before any study specific procedures are performed.


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020

2.
Assign the patient a unique enrolment number (E-code), beginning with ‘E#’, which 
will be used to identify the patient throughout the study.  The E-code to be assigned 
in the Interactive Voice/Web Response System (IxRS). 
3.
Determine patient eligibility.  See Section 3.
4.
At visit 2, perform the randomisation transaction in the IxRS.
Re-enrolment is allowed one single time considering that the patient was not randomised.  The 
same E-code that the patient received at the first enrolment will be used.  All enrolment 
assessments and procedures (see Section 4.1.1), including re-signing the informed consent 
form (ICF), should be performed again.  
3.4
Procedures for handling incorrectly enrolled or randomised 
patients
Patients who fail to meet the eligibility criteria should not, under any circumstances, be 
enrolled or receive IP.  There can be no exceptions to this rule.  Patients who are enrolled, but 
subsequently found not to meet all the eligibility criteria must not be randomised or initiated 
on treatment, and must be withdrawn from the study. 
Where a patient does not meet all the eligibility criteria but is randomised in error, or 
incorrectly started on treatment, the Investigator should inform the AZ study physician 
immediately, and a discussion should occur between the AZ study physician and the 
investigator regarding whether to continue or discontinue the patient from treatment. Study 
treatment must be discontinued in all cases where continued treatment is deemed to pose a 
safety risk to the patient. In those cases where continuation of study therapy is judged not to 
present a concern related to safety and disease management, the rationale for continuing study 
therapy must be clearly documented. Regardless of what is decided about IP all randomised 
patients should remain in the study and the patients should continue to be followed up in 
accordance with defined study procedures. 
3.5
Methods for assigning treatment groups
Randomisation to IP will be performed via IxRS at visit 2 in balanced blocks to ensure 
approximate balance between the treatment groups (1:1).
The IxRS will allocate the IP through a randomisation scheme and provide the randomisation 
number and the appropriate Kit IDs from IP available at the study site.  The randomisation
codes will be computer generated and loaded into the IxRS database.  
At all visits where IP is dispensed, site personnel will do a kit verification in IxRS before
providing the IP bottle to the patient.  
Detailed instruction on use of the IxRS system will be provided to study sites.

3.5.1
Stratification and capping
The recruitment will be continuously monitored in order to achieve adequate proportions of 
patient sub-populations.
Randomisation of patients based on geographic region will be monitored to ensure a global 
representation.  Also, the proportion of patients not on ACE-I or ARB at randomisation, due 
to intolerance, will be monitored to ensure that the target population is reflected in regards to 
background therapy.
3.5.1.1
Stratification
Randomisation will be stratified in IxRS based on patients with and without T2D at the time 
of randomisation in order to ensure approximate balance between treatment groups within 
each sub-population.  T2D at the time of randomisation is based on:

Established diagnosis of T2D 
OR 

HbA1c more or equal to 6.5% (48 mmol/mol) shown at central laboratory 
test at enrolment (visit 1) 
Randomisation will also be stratified in IxRS for patients with UACR >1000 mg/g to ensure 
an equal proportion of patients in each treatment group.
3.5.1.2
Capping
The number of randomised patients with and without T2D will be monitored in order to 
ensure a minimum of 30% in each sub-population.  Randomisation may be capped in IxRS 
(i.e., no more patients in a specific sub-population can be randomised) if the pre-determined 
limit is reached.
The number of patients with eGFR 60 to 75 mL/min/1.73m2 at the time of randomisation, 
shown with a laboratory test at enrolment (visit 1), will be monitored and randomisation in 
IxRS may be capped to ensure that the number of patients in this sub-population does not 
exceed approximately 10%.  
3.6
Methods for ensuring blinding
The blinding of treatment is ensured by using a double-blind technique.  The dapagliflozin 
tablets and the respective placebo tablets will be identical in size, colour, smell, and taste.  The 
bottles with IP will be labelled with unique identification numbers.  
No member of the extended AZ study team, site personnel, or any clinical research 
organization (CRO) handling study data will have access to the randomisation scheme during 
the study.  The AZ personnel or delegate generating the randomisation scheme and the Supply 
Chain Study Management may be able to access the randomisation scheme as appropriate.

Version 4.0

3.7
Methods for unblinding 
Individual treatment codes, indicating the randomised treatment for each patient, will be 
available to the Investigator(s) or pharmacists from the IxRS.  Instructions for code breaking/ 
unblinding will be described in the IxRS user manual that will be provided to each site.  
The treatment code should not be broken except in medical emergencies when the appropriate 
management of the patient requires knowledge of the treatment randomisation.  The 
Investigator documents and reports the action to AZ, without revealing the treatment given to 
patient to the AZ personnel.  It is always the investigator who decides when to unblind but it is 
recommended that the investigator first contacts the AZ study physician for consultation 
regarding the need for unblinding.  If unblinding is deemed necessary, the investigator will 
perform the unblinding in IxRS and must document all actions taken.  The number of 
individuals at the study site who become aware of treatment status should be kept to the 
absolute minimum (including keeping the patient blinded if possible).  Treatment with study 
medication should be continued if possible.  
AZ retains the right to break the code for SAEs that are unexpected and are suspected to be 
causally related to an IP and that potentially require expedited reporting to regulatory 
authorities.  Treatment codes will not be broken for the planned analyses of data until all 
decisions on the evaluability of the data from each individual patient have been made and 
documented.  
3.7.1
Unblinding for bioanalytical laboratory personnel 
PK samples will be analysed at the bioanalytical laboratory only for patients on active IP.  The 
bioanalytical laboratory will therefore have access to the treatment codes but will not share the 
codes with the sponsor or others involved in the study until the blinding is broken for the 
study after closure.
3.8
Restrictions
There are no specific dietary or activity restrictions.  For restricted concomitant medications 
see Section 7.7.  
3.9
Discontinuation of investigational product
If the patient temporarily or permanently discontinues from IP, it is important that the 
scheduled study visits, data collection and procedures continue according to the study protocol 
until study closure (see Section 3.9.3).  
Patients may be discontinued from IP in the following situations:
1.
Patient decision.  The patient is at any time free to discontinue treatment, without 
prejudice to further treatment.


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020
35 (98)
2.
AE or other safety reasons that, in the opinion of the investigator contraindicates 
further dosing with IP.
3.
Severe non-compliance with the study protocol.
4.
DKA, consider to temporary interrupt IP if DKA is suspected.  If DKA is 
confirmed, IP should be discontinued permanently.  
5.
Positive pregnancy test (discontinue IP and notify AZ representative).
3.9.1
Evaluation of volume status and investigational product (IP) dose 
reduction/interruption
Dapagliflozin is a SGLT2 inhibitor which by its mechanism of action reduces the reabsorption 
of glucose and sodium in the proximal tubules in the kidney.  SGLT2 inhibition has a mild 
diuretic effect and an initial haemodynamic change with an initial increase in creatinine may 
occur.
Unexpected acute declines in eGFR 
If an unexpected, acute decline in kidney function is observed, the patient should be evaluated.  
Volume depletion, hypotension, inter-current medical problems and concomitant drugs may 
cause increases in blood creatinine.  Urinary tract infection and urinary obstruction should be 
considered (the latter especially in men).  Several drugs may cause a decline in kidney 
function, especially non-steroidal anti-inflammatory drugs (NSAID) and certain antibiotics 
such as trimethoprim.  If any drug is suspected of causing or contributing to worsening kidney 
function, their use should be re-considered.  
Volume depletion/hypotension
Patients with clinically relevant symptoms/signs of suspected volume depletion and/or 
hypotension, should have their regular medication reviewed, and consideration given to 
reducing the dose of, or stopping concomitant non-essential medications, as assessed on an 
individual basis, including diuretics and drugs that lower BP (except essential treatments – see 
below).  The need for conventional diuretics (or the dose of diuretic used) should be re-
evaluated in light of the patient’s symptoms and signs.  In patients with heart failure, 
discontinuation of diuretic should only be undertaken cautiously.  Hypotension may also occur 
with other BP lowering drugs and once again the need for (and dose of) non-essential agents 
of this type (e.g., calcium channel blockers, alpha adrenoceptor antagonists and nitrates) 
should also be re-considered.
Essential treatments
Essential disease modifying/evidence based treatments such as ACE-I/ARBs, for patients with 
proteinuric CKD and ACE-I/ARBs, sacubitril/valsartan, mineralocorticoid receptor 
antagonists and beta-blockers for patients with heart failure, should NOT be reduced in dose 
or discontinued unless all other measures fail to improve the patient’s situation. In the setting 
of acute worsening of HF or other acute situations it may be acceptable to interrupt treatment 


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020
36 (98)
on a temporary basis in certain circumstances (e.g., an ACE-I/ARB if the patient has 
experienced a significant deterioration in renal function, a beta-blocker if the patient is unduly 
bradycardic or hypotensive, a mineralocorticoid receptor antagonist (MRA) if the patient has 
hyperkalaemia).
IP dose reduction 
If the above mentioned measures do not lead to a resolution of clinically relevant volume 
depletion, hypotension and/or unexpected worsening of kidney function, a dose reduction of 
IP to dapagliflozin 5 mg or matching placebo may be considered and the patient’s condition 
re-evaluated.
Patients at risk of volume depletion
Temporary interruption of IP may be considered in patients thought to be at risk of volume 
depletion/hypotension, such as patients with an acute medical illness potentially causing 
volume depletion because of inadequate fluid intake or fluid/blood loss (e.g., gastroenteritis, 
gastrointestinal haemorrhage), or those undergoing major surgery.  
3.9.2
Investigational product (IP) restart or dose increase from dapagliflozin 5 mg to
10 mg or matching placebo
Restart of randomised IP is always encouraged.  Even if a premature treatment discontinuation 
visit (PTDV) was completed due to the discontinuation of IP, this should not prevent the 
patient to return to randomised treatment if deemed appropriate.  
Every attempt should be made to maintain patients on dapagliflozin 10 mg or matching 
placebo during the course of the study.  If the dose has been decreased to 5 mg or interrupted, 
the dose should be increased back to dapagliflozin 10 mg or matching placebo or 
re-introduced as soon as, in the opinion of the investigator, the patient’s condition is stable.  
3.9.3
Procedures for discontinuation of a patient from investigational product (IP)
At any time, patients are free to discontinue IP.  A patient that decides to discontinue will 
always be asked about the reason(s) and the presence of any AEs.  If possible, the patient will 
be seen and assessed by an investigator.  Adverse events will be followed up, see Section 6, 
and all IP should be returned by the patient.
Generally, AEs, SAEs and potential endpoint events should not lead to IP discontinuation, 
unless there is a clear clinical rationale to do so.
Discontinuation from IP is not the same as complete withdrawal from the study.  If a patient is 
completely withdrawn from study, see Section 3.10.2.
It is essential to collect data for all patients throughout the study.  Optimally, a patient who 
discontinue from IP should for that reason attend all study visits according to plan until study 
closure.  Alternatively, if the patient does not agree to this approach, modified follow-up 
should be arranged.  Patients who agree to some kind of modified follow up are still 


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0

37 (98)
participating in the study.  The modified visits and procedures that are done will be recorded 
in the electronic Case Report Form (eCRF).
If a patient for some reason cannot be reached during the study, every attempt should be made 
to retrieve as much information regarding this patient as possible.  The site should 
continuously try to reach the patient, the patient’s family or pre-identified appropriate contact 
person(s) and, search for information regarding the patient’s status in applicable sources to 
protect the validity of data.  The attempts should be registered in the medical records.
3.9.3.1
Patient undergoes the premature treatment discontinuation visit (PTDV) and 
continues according to plan
The preferred follow-up approach for all patients who prematurely and permanently 
discontinue IP is that the patient undergoes the PTDV and then continues study visits 
according to plan (Table 1).  The PTDV should be done as soon as possible after last IP dose.
3.9.3.2
Patient agrees to undergo modified follow-up
If the patient does not agree to continue study visits according to plan, but agrees to undergo 
modified follow up, a PTDV should be done (Table 1).  The subsequent visits until the study 
closure will be done as modified follow-up (e.g., less frequent visits, regular telephone 
contacts, a contact at study closure, or other means) in order to ascertain whether any 
endpoints or safety events have occurred.
3.10
Criteria for withdrawal 
3.10.1
Screen failures 
Screen failures are enrolled patients who do not fulfil the eligibility criteria for the study, and 
therefore must not be randomised.  These patients should have the reason for study withdrawal 
recorded as ‘Screen failure’ (i.e., patient does not meet the required inclusion/exclusion 
criteria) in the eCRF.  This reason for study withdrawal is only valid for screen failures (not 
randomised patients).  
3.10.2
Withdrawal of informed consent
Patients are free to withdraw from the study at any time (IP and assessments), without 
prejudice to further treatment.  Withdrawal of consent should only occur if the patient does 
not agree to any kind of further assessments or contact whatsoever.  If agreed by the patient, a 
PTDV should be performed.  Discontinuation of IP in itself is not considered withdrawal of 
consent.  
Withdrawal of consent must be ascertained and documented in writing by the investigator who 
must inform the AZ representative and document the withdrawal of consent in the eCRF and 
medical records. 
A patient who withdraws consent will always be asked about the reason(s) and the presence of 
any AE.  The investigator will follow up AEs reported outside of the clinical study.


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020
38 (98)
If a patient withdraws from participation in the study, then his/her enrolment and 
randomisation codes cannot be reused.  Withdrawn patients will not be replaced.  Data 
generated to the time of complete withdrawal from the study will not be destroyed.
To ensure validity of study data, it is very important to collect as much data as possible 
throughout the study and especially vital status (dead or alive) at study closure (also for 
patients who have withdrawn their informed consent).  The investigator will therefore attempt 
to collect information on all patients’ vital status from publicly available sources at study 
closure, even if informed consent has been withdrawn completely, in compliance with local 
privacy laws/practices.  
3.11
Discontinuation of the study
The study may be stopped if, in the judgment of AZ, patients are placed at undue risk because 
of clinically relevant findings. The judgment may be based on recommendations from the 
DMC, see DMC Charter for details.  
In terminating the study, the Sponsor will ensure that adequate consideration is given to the 
protection of the patients’ interests.

a
Local laboratory assessment is optional and may be used to assess eligibility (according to local routine) of eGFR and/or albuminuria. If used, the ICF needs to be signed 
before the optional assessment starts. 
b
Central laboratory assessments include alkaline phosphatase (ALP), ALT, AST, bilirubin, blood urea nitrogen (BUN), creatinine (including eGFR assessment), 
haematocrit, haemoglobin (Hb), HbA1c, phosphate, potassium, and sodium will be analysed as specified in Table 2.
c
Blood and urine samples for future biomarker and/or genetic research is optional.  The biomarker and/or genetic sampling is subject to separate consent by the patient.  
Biomarker samples will be collected at visit 2 and 7, and genetic samples will be collected at visit 2.
d
PK samples will be collected at visit 7.
e
SAEs will be collected from the time of informed consent throughout the study until and including the patient’s last visit.  Potential endpoints, DAEs, AEs leading to dose 
reduction and temporary interruptions and AEs of interest will be collected from randomisation throughout the study until and including the patient’s last visit.
f
The PRO questionnaires will be completed as specified until visit 7 and thereafter every 12 months, and at PTDV and study closure visit (SCV).

4.1
Enrolment period
4.1.1
Visit 1, enrolment (day -14 ±7)
During enrolment period the following assessments and procedures will be completed:

Patient signs the ICF before any study procedures.

Patients who agree to the optional sampling of blood and urine for 
potential future biomarker and/or genetic research will provide their 
consent.  

Patient will be enrolled and assigned an E-code in IxRS.

Optional local laboratory assessment 
Failure to meet the criteria for eGFR and/or albuminuria is expected to be 
the main reason for screen failure in this study.  Therefore, sites will be 
allowed to perform an optional assessment, which will include local 
laboratory assessments of eGFR and/or albuminuria.  Investigators will 
only assess patients who are potentially eligible for the study based on 
their medical conditions and existing therapies, and only those who are 
expected to meet all other entry criteria.  
Local laboratory assessments of eGFR and/or albuminuria will be done 
according to local routine.
When the local results of eGFR are available and indicate that the patient 
may be eligible based on the clinical judgement of the investigator, the 
patient may proceed to further enrolment procedures.

The investigator reviews the inclusion and exclusion criteria.  Patients 
who do not meet these criteria must not be randomised in the study.  

Demography (date of birth, sex, race, ethnic group) and relevant medical 
and surgical history, including smoking history, will be recorded.  

Vital signs (BP, pulse and body weight) and height will be assessed and 
recorded.

Laboratory samples will be collected and sent to the central laboratory as 
specified in Table 2.


Due to high day to day variability of creatinine (eGFR) and UACR, one 
central laboratory retest is allowed, if in the opinion of the investigator 
values are close to the inclusion criteria.

Pregnancy test for women of child-bearing potential will be done locally 
with a dipstick provided by central laboratory.
4.2
Treatment period
4.2.1
Visit 2, randomisation (day 0)
Prior to visit 2, the investigator assesses eligibility based on the laboratory results received from 
central laboratory from visit 1.  Patients not eligible will be considered screen failures and 
should not continue to visit 2.  
At randomisation, the following assessments and procedures will be done:

KDQOL™-36 and EQ-5D-5L will be completed by the patient prior to 
any other site activities and before the patient meets the investigator.

The investigator will re-assess the inclusion and exclusion criteria.

The investigator will perform a general physical examination.  

Vital signs will be assessed and recorded. 

Electrocardiogram (ECG) will be done.

Randomisation to IP will be done in IxRS.

For stratification/capping purposes (see Section 3.5.1), information 
about eGFR and UACR (based on results received from central
laboratory), and whether patient has T2D or not will be recorded in 
IxRS.  

Concomitant medication will be recorded.

Laboratory samples will be collected and sent to the central laboratory as 
specified in Table 2.

DKA (not considered an efficacy variable but will be adjudicated as a 
safety variable)
In addition, eGFR declines ≥50% from baseline, eGFR values <15 mL/min/1.73m2 and new 
diagnosis of T2D will be recorded in the eCRF but will not be adjudicated.  
For each potential endpoint, the investigator or delegate will record the endpoint specific 
information the eCRF.  If the event is subject to adjudication, relevant source documents will 
be assembled.  The source documents and relevant eCRF data will be sent for central 
adjudication.  
Detailed instructions regarding endpoint reporting will be provided to the study sites.  
Additional details about the evaluations of potential endpoints will be described in the Clinical 
Event Adjudication (CEA) charter.  
5.1.2
Classification of death
The CEA committee members will adjudicate and classify all deaths based on definitions 
described in the CEA charter.  For the purpose of the efficacy analysis, deaths will be sub-
classified into CV and non- CV as well as renal primary cause (death due to ESRD when 
dialysis is not given).  The investigator will record the classification of death as CV or non-CV 
death in the eCRF.  
5.1.3
Potential renal endpoints
5.1.3.1
Endpoints related to eGFR decline
eGFR baseline is defined as the mean central laboratory value from visit 1 and visit 2. 
Laboratory values related to eGFR decline will trigger an action by site in the following 
situations: 

Local laboratory values indicate that eGFR value has declined ≥50% 
compared with baseline, or is below 15 mL/min/1.73m2.

As soon as possible, patient should come to the study site for 
confirmation by a central laboratory testing. 
OR

Central laboratory values, collected during a study visit, indicating that 
eGFR value has declined ≥50% compared with baseline, or is below 
15 mL/min/1.73m2.  
The central laboratory will notify site if eGFR is <15 mL/min/1.73m2 or if there is ≥50% 
decline in eGFR compared to baseline. A re-sampling should be done at an unscheduled visit 
after at least 4 weeks, and preferably no later than 6 weeks after the first sampling.  When a

central laboratory value is <15 mL/min/1.73m2 or if there is ≥50% decline in eGFR compared 
to baseline it should be recorded as a potential endpoint in the eCRF. 
The central laboratory will calculate eGFR using CKD-EPI equation (Levey at al 2009).
5.1.3.2
Dialysis and renal transplantation  
If a patient starts dialysis and or go through a renal transplantation this will be recorded in the 
eCRF and submitted for adjudication.  
5.1.3.3
Doubling of serum creatinine
Doubling of serum creatinine (compared to the most recent central laboratory measurement) 
will be recorded in the eCRF and submitted for adjudication.  
Recording of doubling of serum creatinine compared to the most recent central laboratory result 
can be triggered by a local laboratory result OR a central laboratory result.
5.1.4
Hospitalisation for heart failure 
All potential hospitalizations for heart failure should be recorded in the eCRF and submitted to 
adjudication.  The CEA committee members will adjudicate the events as specified in the CEA 
Charter.
5.1.5
New diagnosis of type 2 diabetes (T2D)
New onset of T2D, post randomisation, is defined according to the following criteria:

Reporting of new onset of T2D necessitating initiation of anti-diabetic 
medication 
OR

HbA1c >6.5% (48 mmol/mol) measured by central lab at two consecutive 
study visits
New onset of T2D will be recorded as an AE and on a separate eCRF page.  
5.1.6
Cardiac ischaemic events 
Sites should record potential acute coronary syndromes such as MIs and unstable angina in the 
eCRF and submit for adjudication.  The CEA committee members will adjudicate all potential 
cardiac ischaemic events to decide if they qualify as MIs according to the criteria defined in the 
CEA charter.

Patient reported outcomes (PROs)
PROs is an umbrella term referring to all outcomes and symptoms that are directly reported by 
the patient.  PROs have become important endpoints for regulatory and reimbursement 
authorities when evaluating effectiveness of treatments in clinical trials.  The following PROs 
will be administered in the study: KDQOL™-36 and EQ-5D-5L (see Appendix D).  Patients 
will be asked to complete the EQ-5D-5L and the KDQOL™-36 at the visits as specified in 
Table 1.
5.1.8.1
The Kidney Disease Quality of Life-36 (KDQOL™-36)
The KDQOL™-36 is an abbreviated form of the KDQOL, which is a self-reported 
questionnaire that combines generic and disease-specific components for assessing the health-
related quality of life of patients with CKD, see Appendix D.  
5.1.8.2
EuroQol five-dimensional five-level questionnaire (EQ-5D-5L)
The EQ-5D-5L is a self-reported questionnaire that is used to derive a standardized measure of 
health status, also referred to as a utility score, see Appendix D.  EQ-5D-5L utility scores are 
widely accepted by reimbursement authorities and will be used to support health economic 
evaluations.  
5.1.8.3
Administration of patient reported outcomes (PROs)
All PROs will be administered electronically.  Randomised patients will complete the PRO 
assessments at site using the same handheld electronic device (ePRO).  Each site must allocate 
the responsibility for the administration of the ePROs to a specific individual and, if possible, 
assign a backup person to cover if that individual is absent.  
All assessments should be completed as follows:

Patient must not receive help from relatives, friends, or site personnel to 
answer or clarify the PRO questionnaires, in order to avoid bias.  If a 
patient uses visual aids (e.g., spectacles or contact lenses) for reading and 
does not have them at hand, the patient will be exempted from completing 
the PROs questionnaires on that visit.

Before any other study procedures are conducted at a given visit.

Before being seen by the investigator.

PRO questionnaires must be completed by the patient in private.

The appointed site personnel should explain to patient the value and 
relevance of ePRO assessments and inform that these questions are being 
asked to find out, directly from patients, how he/she feels.  The appointed 
site personnel should also stress that the information is confidential.

recorded in the eCRF.  
Samples will be collected, labelled stored and shipped as detailed in the Laboratory Manual.
5.4.2
Determination of drug concentration
Samples for determination of dapagliflozin concentration in plasma will be analysed by the 
bioanalytical laboratory on behalf of AZ, using an appropriate validated bioanalytical method.  
Full details of the analytical method used will be described in a separate bioanalytical report.  
5.4.3
Storage and destruction of pharmacokinetics (PK) samples
PK samples will be analysed during the course of the study and disposed of after the 
Bioanalytical Report finalization or six months after issuance of the draft Bioanalytical Report 
(whichever is earlier).  The results of the PK analyses will be kept at the laboratory until the 
end of the study to prevent unblinding.  
PK samples may be disposed of or destroyed and anonymised by pooling.  Additional analyses 
may be conducted on the anonymised, pooled PK samples to further evaluate and validate the 
analytical method.  Any results from such analyses may be reported separately from the clinical 
study report (CSR).

exploratory biomarkers to assess correlations with disease activity, effects of dapagliflozin, 
clinical outcomes and toxicity.  Biomarker samples will be collected, handled and shipped as 
detailed in the laboratory manual.  
It is mandatory to obtain the patient’s consent to the donation and use of biological samples.  
The consent date will be recorded in the eCRF.  Patient not consenting to donate biological 
samples for future biomarker analysis are still able to participate in the study, but without 
providing samples for biomarker analysis.  
The biomarkers to be studied will be selected on possible relevance on pathophysiology of the 
studied diseases.
5.7.1
Storage, re-use and destruction of biological samples
Samples will be stored in AZ biobank for a maximum of 15 years from the date of the last 
patient’s last visit, after which they will be destroyed.  The results of this biomarker research 
will be reported either in the CSR itself or as an addendum, or separately in a scientific report 
or publication.  The results of this biomarker research may be pooled with biomarker data from 
other studies with dapagliflozin to generate hypotheses to be tested in future research.  
5.7.2
Labelling and shipment of biological samples
The Principal Investigator (PI) ensures that samples are labelled and shipped in accordance 
with the Laboratory Manual and the Biological Substance, Category B Regulations (materials 
containing or suspected to contain infectious substances that do not meet Category A criteria), 
see Appendix B.  
Any samples identified as Infectious Category A materials are not shipped and no further 
samples will be taken from the patient unless agreed with AZ and appropriate labelling, 
shipment and containment provisions are approved.  Samples can be shipped to specialist labs 
around the world and analysed by academic collaborators or commercial partners.

while in storage at the study site until shipment or disposal (where appropriate) and keeps 
documentation of receipt of arrival.  
The sample receiver keeps full traceability of the samples while in storage and during use until 
used or disposed of or until further shipment and keeps documentation of receipt of arrival.  
AZ keeps oversight of the entire life cycle through internal procedures, monitoring of study 
sites and auditing of external laboratory providers.  
Samples retained for further use are registered in the AZ biobank during the entire life cycle.  
5.7.4
Withdrawal of informed consent for donated biological samples 
If a patient withdraws consent to the use of donated biological samples, the samples will be 
disposed of/destroyed, and the action documented.  If samples are already analysed, AZ is not 
obliged to destroy the results of this research.  
As collection of donated biological samples is an optional part of the study, the patient may 
continue in the study.
The PI:

Ensures patients’ withdrawal of informed consent to the use of donated 
samples is notified as soon as possible to AZ.

Ensures that biological samples from that patient, if stored at the study site, 
are identified as soon as possible, disposed of /destroyed, and the action 
documented.

SAFETY REPORTING AND MEDICAL MANAGEMENT
The PI is responsible for ensuring that all personnel involved in the study are familiar with the 
content of this section.  
6.1
Definition of adverse events
An AE is the development of an undesirable medical condition or the deterioration of a pre-
existing medical condition following or during exposure to a pharmaceutical product, whether 
or not considered causally related to the product.  An undesirable medical condition can be 
symptoms (e.g., nausea chest pain), signs (e.g., tachycardia, enlarged liver) or the abnormal 
results of an investigation (e.g., laboratory findings, ECG).  In clinical studies, an AE can 
include an undesirable medical condition occurring at any time, including run-in or washout 
periods, even if no study treatment has been administered.  
The term AE is used to include both serious and non-serious AEs.  The term AE in this 
document refers only to the categories of events described in Section 6.3.  
6.2
Definitions of serious adverse event (SAE)
An SAE is an AE occurring during any study phase (i.e., run-in, treatment, washout and follow-
up), that fulfils one or more of the following criteria:

Results in death

Is immediately life-threatening

Requires in-patient hospitalisation or prolongation of existing
hospitalisation

Results in persistent or significant disability/incapacity or substantial 
disruption of the ability to conduct normal life functions

Is a congenital abnormality or birth defect

Is an important medical event that may jeopardize the patient or may 
require medical intervention to prevent one of the outcomes listed above
For further guidance on the definition of a SAE, see Appendix A to the Clinical Study Protocol.  
6.3
Recording of adverse events
6.3.1
Time period for collection of adverse events
AEs will be collected from randomisation (visit 2) throughout the treatment period until and

and including the patient's last visit.  
AEs should be recorded in the eCRF only if:

It qualifies as an SAE (as defined in Section 6.2)

The AE is the reason for permanent discontinuation from IP (DAE)

The AE is the reason for IP interruption or dose reduction

It qualifies as an AE of interest

Volume depletion 

Renal events 

Major hypoglycaemic events

Fractures

Potential DKAs

AEs leading to amputation and AEs leading to a risk for lower limb 
amputations (“preceding events”)

A potential endpoint (see Section 5.1) fulfils the AE criteria. NB: not all 
potential endpoints are per definition an AE e.g., a potential endpoint 
solely related to laboratory findings (see Section 6.3.7) should not be 
recorded unless any of the above mentioned criteria is met. 
An AE/SAE could be associated with more than one potential endpoint. In such scenario, only 
one AE/SAE should be recorded but all potential endpoints should be recorded individually.
6.3.2
Adverse events of interest
6.3.2.1
Volume depletion
Events of volume depletion (e.g., dehydration, hypovolemia, or hypotension) will be recorded 
in the eCRF as AEs.  
6.3.2.2
Renal events
Renal events, such as an acute clinically relevant decline in kidney function as judged by the 
investigator, will be recorded in the eCRF as AEs. If the event also qualifies as a potential 
endpoint as defined in Section 5.1.3.2, a separate eCRF will be completed.

6.3.2.3
Major hypoglycaemic events
A major hypoglycaemic event is defined as an event that requires assistance of another person 
to actively administer carbohydrates, glucagon, or take other corrective actions.
Plasma glucose concentrations may not be available during an event, but neurological recovery 
following the corrective actions is considered sufficient evidence that the event was induced by 
a low plasma glucose concentration.  Major hypoglycaemic episodes will be recorded in the 
eCRF as an AE and on an additional eCRF page.  
6.3.2.4
Fractures
All fractures will be recorded in the eCRF as AEs.
6.3.2.5
Diabetic ketoacidosis (DKA)
All potential events of DKA will be recorded in the eCRF and submitted to an independent 
DKA Adjudication Committee (see Section 6.8.5).
6.3.2.6
Adverse events (AEs) leading to amputation and AEs leading to a risk for lower 
limb amputations (“preceding events”)
To ensure that data on amputations is systematically collected, amputations and underlying 
conditions relevant to amputation will be recorded on a specific eCRF page. The adverse event 
leading to amputation should be recorded in the eCRF as AE/SAE.
In addition, non-serious and serious events potentially placing the patient at risk for a lower 
limb amputation (“preceding events”) should also be recorded in the eCRF as AE/SAE, 
whether or not an amputation has taken place. The lower limb “preceding events” of interest 
include diabetic foot related conditions, vascular, wounds/injury/trauma, infection and 
neuropathy. If any of these or other potentially relevant event have occurred, relevant 
information must be provided (this will be collected on a dedicated eCRF page - for details see 
eCRF instruction).
6.3.3
Follow-up of unresolved adverse events
Any AEs that are unresolved at the patient’s last study visit in the study are followed up by the 
investigator for as long as medically indicated, but without further recording in the CRF.  AZ 
retains the right to request additional information for any patient with ongoing AE(s)/SAE(s) at 
the end of the study, if judged necessary.  
6.3.4
Variables 
The following variables will be collect for each AE:

AE (verbatim)

The date when the AE started and stopped


Clinical Study Protocol


Maximum intensity (mild/moderate/severe)

Whether the AE is serious or not

Investigator causality rating against the IP (yes or no)

Action taken with regard to IP

Outcome
In addition, the following variables will be collected for SAEs:

Date AE met criteria for serious AE

Date investigator became aware of serious AE

AE is serious due to

Date of hospitalisation

Date of discharge

Probable cause of death

medication

Description of AE
It is important to distinguish between serious and severe AEs.  Severity is a measure of 
intensity whereas seriousness is defined by the criteria described in Section 6.2. An AE of 
severe intensity need not necessarily be considered serious. For example, nausea that persists 
for several hours may be considered severe nausea, but not a SAE unless it meets the criteria 
shown in Section 6.2. On the other hand, a stroke that results in only a limited degree of 
disability may be considered a mild stroke but would be a SAE when it satisfies the criteria 
shown in Section 6.2.  
6.3.5
Causality collection
The investigator will assess causal relationship between IP and each AE, and answer ‘yes’ or 
‘no’ to the question ‘Do you consider that there is a reasonable possibility that the event may 
have been caused by the IP?’


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020
62 (98)
For SAEs causal relationship will also be assessed for other medication and study procedures.  
Note that for SAEs that could be associated with any study procedure the causal relationship is 
implied as ‘yes’.  
A guide to the interpretation of the causality question is found in Appendix A.
6.3.6
Adverse events based on signs and symptoms
All AEs spontaneously reported by the patient, or reported in response to the open question 
from the site personnel: ‘Have you had any health problems since the previous visit/you were 
last asked?’, or revealed by observation, will be collected and recorded in the eCRF (if 
fulfilling the criteria for recording as specified in Section 6.3.1). When collecting AEs, the 
recording of diagnoses is preferred (when possible) to recording a list of signs and symptoms.  
However, if a diagnosis is known and there are other signs or symptoms that are not generally 
part of the diagnosis, the diagnosis and each sign or symptom will be recorded separately.  
6.3.7
Adverse events based on examinations and tests
The results from protocol mandated laboratory tests and vital signs will be summarised in the 
CSR. Deterioration as compared with baseline in protocol-mandated laboratory values or vital 
signs should therefore only be reported as AEs if they fulfil any of the SAE criteria or are the 
reason for discontinuation of treatment with the investigational product. 
If deterioration in a laboratory value/vital sign is associated with clinical signs and symptoms, 
the sign or symptom will be reported as an AE and the associated laboratory result/vital sign 
will be considered as additional information.  Wherever possible the reporting investigator uses 
the clinical, rather than the laboratory term (e.g., anaemia versus low Hb value).  In the absence 
of clinical signs or symptoms, clinically relevant deteriorations in non-mandated parameters 
should be reported as AE(s).  
6.4
Reporting of serious adverse events (SAEs)
All SAEs have to be reported, whether or not considered causally related to the IP, or to the 
study procedure(s).  All SAEs will be recorded in the eCRF.  
If any SAE occurs in the course of the study, then Investigators or other site personnel inform 
the appropriate AZ representatives within one day i.e., immediately but no later than 24 hours 
of when he or she becomes aware of it.  
The designated AZ representative works with the investigator to ensure that all the necessary 
information is provided to the AZ Patient Safety data entry site within 1 calendar day of initial 
receipt for fatal and life threatening events and within 5 calendar days of initial receipt for all 
other SAEs.  
For fatal or life-threatening AEs where important or relevant information is missing, active 
follow-up is undertaken immediately.  Investigators or other site personnel inform AZ 


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020
63 (98)
representatives of any follow-up information on a previously reported SAE within one calendar 
day i.e., immediately but no later than 24 hours of when he or she becomes aware of it.  
Once the Investigators or other site personnel indicate an AE is serious in the WBDC system, 
an automated email alert is sent to the designated AZ representative.  
If the WBDC system is not available, then the investigator or other site personnel reports a SAE 
to the appropriate AZ representative by telephone in accordance with SAE reporting timelines.  
The AZ representative will advise the investigator/site personnel how to proceed. 
6.4.1
Reporting of serious adverse events (SAEs) considered to be potential endpoints
In order to avoid unnecessary unblinding of efficacy endpoint events, certain SAEs which are 
also potential endpoints (i.e., fatal events and heart failure events) will not be reported to health 
authorities.  Clinical data for the above mentioned events will be recorded as AEs/SAEs as well 
as on separate event forms in the eCRF.  Recording of a suspected endpoint should be done 
within the same timeframes as defined for SAEs (see Section 6.4).  
In addition, fatal AEs and potential heart failure endpoints will be centrally adjudicated by an 
independent CEA committee (see Section 5.1.1 and 6.8.4). If adjudication confirms the 
endpoint, the SAE will not be reported to health authorities. However, if it is determined by the 
CEA committee that a potential endpoint in the above mentioned categories does not meet the 
endpoint criteria, the event will be reported (according to the timelines specified in Section
6.3.1) to AZ patient safety data entry site and if applicable to the health authorities (note that 
the clock starts when the adjudication results are available).
6.5
Overdose
Dapagliflozin has been well tolerated at doses of up to 500 mg/day in single dose testing in 
healthy volunteers and up to 100 mg/day in repeat dose testing for 14 days in healthy 
volunteers and patients with T2D.  Suspected single intake of more than 50 tablets of 10 mg 
dapagliflozin tablets or repeated intake of more than 10 tablets of 10 mg dapagliflozin tablets 
should be recorded in the eCRF.  If an overdose is suspected, monitoring of vital functions as 
well as treatment should be performed as appropriate.  
For further information regarding overdose, refer to the IB.

An overdose with associated AEs is recorded as the AE 
diagnosis/symptoms on the relevant AE modules in the eCRF and on the 
Overdose eCRF module.  

An overdose without associated symptoms is only recorded in the 
Overdose eCRF module.  


Clinical Study Protocol

If an overdose on an AZ study drug occurs in the course of the study, then the investigator or 
other site personnel inform appropriate AZ representatives immediately, or no later than 
24 hours of when he or she becomes aware of it.  
The designated AZ representative works with the investigator to ensure that all relevant 
information is provided to the AZ Patient Safety data entry site.  
For overdoses associated with a SAE, the standard reporting timelines apply (see Section 6.4).  
For other overdoses, reporting must occur within 30 days.  
6.6
Pregnancy
All pregnancies and outcomes of pregnancy should be reported to AZ.  
6.6.1
Maternal exposure
If a patient becomes pregnant during the course of the study IP should be discontinued 
immediately.  
Pregnancy itself is not regarded as an AE unless there is a suspicion that the IP under study 
may have interfered with the effectiveness of a contraceptive medication. Congenital 
abnormalities/birth defects and spontaneous miscarriages should be reported and handled as 
SAEs. Elective abortions without complications should not be handled as AEs.  The outcome of 
all pregnancies (spontaneous miscarriage, elective termination, ectopic pregnancy, normal birth 
or congenital abnormality) should be followed up and documented even if the patient was 
discontinued from the study.  
If any pregnancy occurs during the course of the study, then the investigator or other site 
personnel informs the appropriate AZ representatives within 1 day i.e., immediately but no 
later than 24 hours of when he or she becomes aware of it.  
The designated AZ representative works with the investigator to ensure that all relevant 
information is provided to the AZ Patient Safety data entry site within 1 or 5 calendar days for 
SAEs (see Section 6.4) and within 30 days for all other pregnancies.  
The same timelines apply when outcome information is available.  
The PREGREP module in the eCRF is used to report the pregnancy and the PREGOUT paper 
CRF form is used to report the outcome of the pregnancy.

amendments, supervision of the study conduct and progress, development of any protocol 
amendments needed during the study, liaison with the CEA Committee and DMC, as needed, 
development of the statistical analysis plan (SAP), interpretation of the final data and reporting 
(presentations at international congresses and publications in peer reviewed journals) of the 
study.  
The Executive Committee will make recommendations to AZ with regard to early stopping or 
modifications of the study based on the information received from the DMC.  The Executive 
Committee will be comprised of designated international academic leaders and non-voting 
members of the Sponsor, and will operate under an Executive Committee charter.  
6.8.2
National Lead Investigator (NLI) Committee
The National Lead Investigator (NLI) Committee will be comprised of NLIs from each country 
where the study is conducted and supervised by the Executive Committee.  Members of the 
committee will be responsible for providing clinical guidance on study implementation, 
recruitment and study conduct in their respective country.  
6.8.3
Data Monitoring Committee (DMC)
An independent DMC will be appointed and will report to the Executive Committee.  The 
DMC will be responsible for safeguarding the interests of the patients in the study by assessing 
the safety of the IP during the study, and for reviewing the overall conduct of the study.  The 
DMC will have access to the individual treatment codes and be able to merge these with the 
collected study data while the study is ongoing.  A DMC charter will be prepared to detail 
precise roles and responsibilities and procedures to ensure maintenance of the blinding and 
integrity of the study in the review of accumulating data and interactions with the Executive 
Committee.  
6.8.4
Clinical Event Adjudication (CEA) Committee
The role of the CEA committee is to independently review, interpret and adjudicate potential 
endpoints that are experienced by the patients.  Endpoints will be identified preliminary by the 
Investigators, and also by AZ personnel or in the CEA process as specified in the CEA charter.  
The CEA committee members will not have access to individual treatment codes for any 
patient or clinical efficacy endpoint and safety event.  The precise responsibilities and 
procedures applicable for CEA will be detailed in the CEA charter.  
6.8.5
Diabetic Ketoacidosis Adjudication Committee T2D
All potential events of DKA will be submitted to an independent DKA Adjudication 
Committee.  The committee will be kept blinded to the treatment codes.  A separate DKA 
Adjudication Manual will define and describe the procedures for the collection of DKA 
information, handling, adjudication criteria and reporting of these events.

Medication Error
For the purposes of this clinical study a medication error is an unintended failure or mistake in 
the treatment process for an AstraZeneca study drug that either causes harm to the subject or 
has the potential to cause harm to the subject. 
A medication error is not lack of efficacy of the drug, but rather a human or process related 
failure while the drug is in control of the study site staff or subject.
Medication error includes situations where an error 

occurred

was identified and intercepted before the subject received the drug

did not occur, but circumstances were recognized that could have led to an error
Examples of events to be reported in clinical studies as medication errors:

Drug name confusion

Dispensing error e.g. medication prepared incorrectly, even if it was not actually given 
to the subject

Drug not administered as indicated, for example, wrong route or wrong site of 
administration

Drug not taken as indicated e.g. tablet dissolved in water when it should be taken as a 
solid tablet 

Drug not stored as instructed e.g. kept in the fridge when it should be at room 
temperature 

Wrong subject received the medication (excluding IVRS/IWRS errors)

Wrong drug administered to subject (excluding IVRS/IWRS errors)
Examples of events that do not require reporting as medication errors in clinical studies:

Errors related to or resulting from IVRS/IWRS - including those which lead to one of 
the above listed events that would otherwise have been a medication error 

Subject accidentally missed drug dose(s) e.g. forgot to take medication

Accidental overdose (will be captured as an overdose)

Subject failed to return unused medication or empty packaging

Errors related to background and rescue medication, or standard of care medication in 
open label studies, even if an AZ product 
Medication errors are not regarded as AEs but AEs may occur as a consequence of the 
medication error.

If a medication error occurs in the course of the study, then the Investigator or other site 
personnel informs the appropriate AstraZeneca representatives within 1 day i.e., immediately 
but no later than 24 hours of when he or she becomes aware of it.
The designated AstraZeneca representative works with the Investigator to ensure that all 
relevant information is completed within 1 or 5 calendar days if there is an SAE associated with 
the medication error (see Section 6.4) and within 30 days for all other medication errors.

7.2
Dose and treatment regimens
At randomisation, visit 2 (day 0), eligible patients will be randomly assigned to 1 of 2 
treatments:

Dapagliflozin 10 mg, given once daily per oral use

Placebo – one placebo tablet to match dapagliflozin 10 mg, given once 
daily per oral use
Randomisation and treatment pack assignment will be managed via an IxRS at visit 2.  The IP 
should be taken per oral once daily in the morning and at approximately the same time every 
day, during the study period.  If the patient, for any reason prefers not to administer the IP in 
the morning, any other time point during the day may be applied, provided the patient routinely 
administer the IP in approximate 24 hours intervals.  The IP should not be altered (e.g., 
crushed, put in another vehicle) and should not be given by nasogastric tube or other routes.

If the dose is adjusted (i.e., lowered to 5 mg or increased back to 10 mg) during the study (see 
Section 3.9.1 and 3.9.2), this will be handled in IxRS and the dose change will be recorded in 
the eCRF.
Missed doses of dapagliflozin or placebo blinded study medication should not be compensated 
for (i.e., if a dose is missed, the next regularly scheduled dose should be taken and should not 
be doubled).
7.3
Labelling
Labels will be prepared in accordance with Good Manufacturing Practice (GMP) and local 
regulatory guidelines.  The labels will fulfil GMP Annex 13 requirements for labelling.  Label 
text will be translated into local language.  
7.4
Storage
All IPs should be kept in a secure place under appropriate storage conditions.  The IP label on 
the bottle specifies the appropriate storage.  
7.5
Compliance
The administration of all IPs should be recorded in the appropriate sections of the eCRF.
7.6
Accountability
The study drug provided for this study will be used only as directed.  
The study personnel will account for all study drugs dispensed to and returned from the patient.  
Patients will be asked to bring all unused IP and empty packages to the study site at all visits.  
The investigator or delegate will record the amount of returned tablets in the eCRF.  Any 
patient found to be noncompliant would be counselled on the importance of taking their IP as 
prescribed.
Any IP deliberately or accidentally destroyed must be recorded.  Any discrepancy between 
dispensed and returned IP should be explained.
The investigator will retain the returned medication until the AZ representative or delegate 
collects it, along with any medication not dispensed.  The AZ representative or delegate is 
responsible for confirming that the investigator or delegate has recorded the quantities of 
returned and unused tablets at a patient level before medication is destroyed.  The AZ 
representative or delegate will advise on the appropriate method for destruction of unused IP.
7.7
Concomitant and other treatments 
All patients should be treated according to regional standards of care for CV risk factors (e.g., 
BP, lipids, and antithrombotic treatment), diabetes and CKD complications (e.g., 
hyperphosphatemia, hyperparathyroidism, hyperkalaemia, acidosis and renal anaemia).

7.7.1
Restricted medication
Treatment with non-steroidal anti-inflammatory drugs (NSAID) should, if possible, be avoided 
during the study.
7.7.2
Prohibited medication
Concomitant treatment (i.e., treatment in combination with IP) with open label SGLT2 
inhibitors e.g., dapagliflozin, empagliflozin, canagliflozin, ertugliflozin, tofogliflozin and 
luseogliflozin and fix dose combinations containing these drugs is prohibited.  Also in 
situations when the patient is not on IP, treatment with open label SGLT2 inhibitors during the 
study, could interfere with the interpretation of study results and should therefore not be given 
unless all other possibilities to treat the patient properly has been considered.  
7.7.3
Recording of concomitant treatment
Detailed recording of medications related to CKD (see Section 7.7.4), diabetes (see Section 
7.7.5) as well as other relevant cardiovascular medications (e.g., statins, antihypertensive and 
antithrombotic agents) will be made throughout the study. In addition, concomitant medications 
will be recorded at the time of any SAEs, potential endpoints and AEs of interest (as defined in
Section 6.3). Recording of other concomitant medications will be made at randomisation 
(visit 2) and at SCV.
7.7.4
Chronic kidney disease (CKD) medications
To be eligible, the patient needs to be on stable and for the patient maximum tolerated labelled 
daily dose of ACE-I or ARB for at least 4 weeks before visit 1, if not medically 
contraindicated.  If the patient is not on an ACE-I or ARB at the time of enrolment the reason 
will be recorded in the eCRF.
Details regarding the following CKD related treatments will be recorded in the eCRF 
throughout the study:

RAAS inhibition: ACE-I/ARBs, renin inhibitors, mineralocorticoid 
antagonists

Diuretics: Loop diuretics, thiazide diuretics and other diuretics

Treatment of underlying kidney disease: cytotoxic agents, 
immunosuppressive agents, other immunotherapy

Phosphate binders

Potassium binders

Anti-diabetes treatment of patients with established diagnosis of type 2 diabetes 
(T2D)
Patients with T2D at randomisation in this study will continue their T2D treatment.  Treatment 
should be based on established guidelines and according to local laboratory values.  Patients are 
eligible for adjustments in their anti-diabetes treatment at the discretion of their diabetes health 
care provider.  Diabetes medications at baseline and any changes throughout the study, will be 
recorded in the eCRF.  
7.7.5.1
Use of medications known to cause hypoglycaemia in type 2 diabetes (T2D) 
patients 
Insulin and insulin secretagogues are known to cause hypoglycaemia.  Therefore, patients 
treated with insulin or sulfonylurea (SU) have a higher risk of experiencing hypoglycaemic
events compared with those treated with other antidiabetic agents.  Therefore a lower dose of 
insulin or insulin secretagogues may be required to minimize the risk of hypoglycaemia when 
used in combination with study medication.
Reduction of insulin by 10 to 20% (total daily dose) and SU by 25 to 50% and increased 
frequency of blood glucose monitoring may be considered in patients receiving insulin and/or 
SU and with baseline HbA1c ≤7% at randomisation.
7.7.6
Other concomitant treatment
Medications other than described above, which is considered necessary for the patient’s safety 
and wellbeing, may be given at the discretion of the investigator and recorded in the 
appropriate sections of the eCRF, as applicable.

STATISTICAL ANALYSES BY ASTRAZENECA (AZ)
8.1
Statistical considerations
All personnel involved with the analysis of the study will remain blinded until database lock 
and protocol violations have been identified and documented.  
A comprehensive SAP will be developed prior to first randomised patient and any subsequent 
amendments will be documented, with final amendments completed prior to unblinding of the 
data.
The results of the key study outcome will be independently validated by an external statistical 
team.

Sample size estimate
The primary objective of the study is to determine the superiority of dapagliflozin versus 
placebo in reducing the incidence of the primary composite endpoint.  Assuming a true hazard 
ratio of 0.78 between dapagliflozin and placebo, using a one-sided alpha of 2.5%, 681 primary 
endpoints will provide a statistical power of 90% for the test of the primary composite 
endpoint.  This is based on an overall 1:1 allocation between dapagliflozin and placebo.  The 
study is event-driven.  The assumed hazard ratio of 0.78 is considered as clinically relevant and 
has taken into account the renal outcomes in the EMPA-REG trial.  
With an annual event rate of 7.5% in the placebo treatment group, 4000 patients are estimated 
to provide the required number of primary events, based on an anticipated recruitment period of 
24 months and an average follow-up period of approximately 33 months.  The assumed placebo 
event rate of 7.5% is based on a review of published data in the CKD population. In addition, 
the expected number of patients who will be lost to follow-up is expected to be small; hence, 
they are not considered in the determination of the sample size.  
8.3
Definitions of analysis sets
8.3.1
Full analysis set (FAS)
All patients who have been randomised to study treatment will be included in the full analysis 
set (FAS) irrespective of their protocol adherence and continued participation in the study.  
Patients will be analysed according to their randomised IP assignment, irrespective of the 
treatment actually received.  The FAS will be considered the primary analysis set for the 
primary and secondary variables and for the exploratory efficacy variables.  
8.3.2
Safety analysis set
All patients who receive at least one dose of randomised treatment will be included in the 
safety population.  Patients will be analysed according to the treatment actually received.  The 
Safety analysis set will be considered the primary analysis set for all safety variables.

Closed testing procedure
A closed testing procedure including a pre-specified hierarchical ordering of the primary and 
secondary endpoints will be utilized.  The Type I error will be controlled at a one-sided 
0.025 level for multiplicity across primary and secondary endpoints.  Statistical significance 
will be assessed in the pre-specified order of the endpoints as specified in Section 2.1 and 2.2.  
The testing procedure will continue down the hierarchy if the preceding endpoint is rejected at 
a one-sided 0.025 level and will stop if the preceding endpoint is not rejected at a one-sided 
0.025 level.  Exploratory endpoints will be tested at a one-sided 0.025 level without adjustment 
for multiplicity.
8.5.3
Analysis of the primary variable (s)
The primary variable is the time to first event included in the primary composite endpoint.  The 
primary analysis will be based on the intention to treat (ITT) principle using the FAS.  
In the analysis of the primary composite endpoint, treatments (dapagliflozin versus placebo) 
will be compared using a Cox proportional hazards model with a factor for treatment group, 
stratified by randomisation stratification factors (T2D, UACR), and adjusting for eGFR. In 
general, the analysis will use each patient's last contact as the censoring date for patients 
without any primary events.  The p-value, hazard ratio (HR) and 95% confidence interval will 
be reported.
The contribution of each component of the primary composite endpoint to the overall treatment 
effect will be examined.  Methods similar to those described for the primary analysis will be 
used to separately analyse the time from randomisation to the first occurrence of each 
component of the primary composite endpoint.  Last contact will be treated as the censoring 
date for patients without the endpoint of interest.  Hazard ratios (HR) and 95% confidence 
intervals will be reported.
Kaplan-Meier estimates of the cumulative incidence to the first occurrence of any event in the 
primary endpoint will be calculated and plotted, for overall analysis and for the individual 
components.

8.5.4
Analysis of the secondary variables
The secondary variables will be analysed in the similar manner as the primary variable.  
8.5.5
Subgroup analysis
Subgroup variables for the primary efficacy endpoint and secondary efficacy endpoints include 
demography, baseline disease characteristics, baseline concomitant medications and others.
Cox proportional hazards models will be performed to examine treatment effects within 
relevant subgroups separately.  The p-values for the subgroup analyses will not be adjusted for 
multiple comparisons as the tests are exploratory and will be interpreted descriptively.  Event 
rates by treatment and HRs with 95% confidence intervals will be reported for each subgroup.  
HRs and CIs for overall analysis and subgroups will be presented with forest plots.  Further 
details of the subgroup analysis, including the list of subgroup variables, will be provided in the 
SAP.

Interim analysis
Not applicable.
8.5.7
Sensitivity analysis
Details of the sensitivity analysis will be provided in the SAP.  
8.5.8
Analysis of safety variables
The number and percent of patients with SAEs, DAEs, AEs leading to dose reductions and 
temporary interruptions, AEs of interest, will be summarized by treatment group.  Changes in 
clinical chemistry/haematology parameters will be summarized over time by treatment group.  
In addition, the number and percent of patients with a marked abnormality in clinical laboratory 
tests will be summarized over time by treatment group.  For safety analyses, summaries will be 
provided using both on treatment observations and using all observations regardless of whether 
patients are on or off study treatment.  
8.5.9
Exploratory analysis
The exploratory variables (excluding PK and biomarkers for future exploratory research) will 
be analysed as specified in the SAP.

The PI will ensure that appropriate training relevant to the study is given to all site personnel, 
and that any new information relevant to the performance of this study is forwarded to the 
personnel involved.  
The PI will maintain a record of all individuals involved in the study (medical, nursing and 
other personnel).  
9.2
Monitoring of the study
During the study, an AZ representative will have regular contacts with the study site, including 
visits to:

Provide information and support to the investigator(s) and site personnel.

Confirm that facilities remain acceptable.

Confirm that the investigational team is adhering to the protocol; that data 
are being accurately and timely recorded in the eCRFs; that biological 
samples are handled in accordance with the Laboratory Manual and that 
study drug accountability checks are being performed.

Perform source data verification (a comparison of the data in the eCRFs 
with the patient’s medical records at the hospital or practice, and other 
records relevant to the study) including verification of informed consent of 
participating patients.  This will require direct access to all original records 
for each patient (e.g., medical records).

Perform source data review, i.e., review of source documentation to check 
quality of source, review protocol compliance, ensure critical processes 
and source documentation are adequate.

Ensure withdrawal of informed consent to the use of the patient’s 
biological samples is reported and biological samples are identified and 
disposed of/destroyed accordingly, and the action is documented, and 
reported to the patient.
The AZ representative will be available between visits if the investigator(s) or other personnel 
at the study site needs information and advice about the study conduct.
9.2.1
Risk based quality management
Quality by design will be implemented, including a focus on identifying key risks to patient 
safety, data quality, and Good Clinical Practice (GCP)/regulatory compliance, to build quality 
into the design, conduct, analysis and reporting of the study.  
A risk based monitoring approach will be applied for this study.  This includes a mix of 
monitoring strategies: on-site monitoring, remote monitoring (site level monitoring activities

Appendix A
Additional Safety Information
Further Guidance on the Definition of a Serious Adverse Event (SAE)
Life threatening
‘Life-threatening’ means that the patient was at immediate risk of death from the AE as it 
occurred or it is suspected that use or continued use of the product would result in the subject’s 
death.  ‘Life-threatening’ does not mean that had an AE occurred in a more severe form it 
might have caused death (e.g., hepatitis that resolved without hepatic failure).  
Hospitalisation
Outpatient treatment in an emergency room is not in itself a serious AE, although the reasons 
for it may be (e.g., bronchospasm, laryngeal oedema).  Hospital admissions and/or surgical 
operations planned before or during a study are not considered AEs if the illness or disease 
existed before the patient was enrolled in the study, provided that it did not deteriorate in an 
unexpected way during the study.  
Important medical event or medical intervention
Medical and scientific judgement should be exercised in deciding whether a case is serious in 
situations where important medical events may not be immediately life threatening or result in 
death, hospitalisation, disability or incapacity but may jeopardize the patient or may require 
medical intervention to prevent one or more outcomes listed in the definition of serious.  These 
should usually be considered as serious.  
Simply stopping the suspect drug does not mean that it is an important medical event; medical 
judgement must be used.  

Angioedema not severe enough to require intubation but requiring iv 
hydrocortisone treatment

Hepatotoxicity caused by paracetamol (acetaminophen) overdose requiring 
treatment with N-acetylcysteine

Intensive treatment in an emergency room or at home for allergic 
bronchospasm

Blood dyscrasias (e.g., neutropenia or anaemia requiring blood transfusion, 
etc.) or convulsions that do not result in hospitalisation

Development of drug dependency or drug abuse
A Guide to Interpreting the Causality Question
When making an assessment of causality consider the following factors when deciding if there 
is a ‘reasonable possibility’ that an AE may have been caused by the drug.  


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0
Date 17 March 2020
83 (98)

Time Course.  Exposure to suspect drug.  Has the patient actually received 
the suspect drug?  Did the AE occur in a reasonable temporal relationship 
to the administration of the suspect drug?

Consistency with known drug profile.  Was the AE consistent with the 
previous knowledge of the suspect drug (pharmacology and toxicology) or 
drugs of the same pharmacological class? Or could the AE be anticipated 
from its pharmacological properties?

De-challenge experience.  Did the AE resolve or improve on stopping or 
reducing the dose of the suspect drug?

No alternative cause.  The AE cannot be reasonably explained by another
aetiology such as the underlying disease, other drugs, other host or 
environmental factors.  

Re-challenge experience.  Did the AE reoccur if the suspected drug was 
reintroduced after having been stopped? AZ would not normally 
recommend or support a re-challenge.  

Laboratory tests.  A specific laboratory investigation (if performed) has 
confirmed the relationship.  
In difficult cases, other factors could be considered such as:

Is this a recognized feature of overdose of the drug?

Is there a known mechanism?
Causality of ‘related’ is made if following a review of the relevant data, there is evidence for a 
‘reasonable possibility’ of a causal relationship for the individual case.  The expression 
‘reasonable possibility’ of a causal relationship is meant to convey, in general, that there are 
facts (evidence) or arguments to suggest a causal relationship.  
The causality assessment is performed based on the available data including enough 
information to make an informed judgment.  With limited or insufficient information in the 
case, it is likely that the event(s) will be assessed as ‘not related’.  
Causal relationship in cases where the disease under study has deteriorated due to lack of effect 
should be classified as no reasonable possibility.

International Airline Transportation Association (IATA) 6.2 
Guidance Document
Labelling and shipment of biohazard samples
International Airline Transportation Association (IATA) classifies biohazardous agents into 
3 categories.  For transport purposes the classification of infectious substances according to risk 
groups was removed from the Dangerous Goods Regulations (DGR) in the 46th edition (2005).  
Infectious substances are now classified either as Category A, Category B or Exempt.  There is 
no direct relationship between Risk Groups and categories A and B.  
Category A Infectious Substances are infectious substances in a form that, when exposure to 
it occurs, is capable of causing permanent disability, life-threatening or fatal disease in 
otherwise healthy humans or animals.  Category A pathogens are e.g., Ebola, Lassa fever virus:

Are to be packed and shipped in accordance with IATA Instruction 602 
Category B Infectious Substances are infectious Substances that do not meet the criteria for 
inclusion in Category A.  Category B pathogens are e.g., Hepatitis A, B, C, D, and E viruses, 
Human immunodeficiency virus (HIV) types 1 and 2.  They are assigned the following UN 
number and proper shipping name:

UN 3373 – Biological Substance, Category B

Are to be packed in accordance with UN3373 and IATA 650
Exempt - all other materials with minimal risk of containing pathogens

Clinical trial samples will fall into Category B or exempt under IATA 
regulations.

Clinical trial samples will routinely be packed and transported at ambient 
temperature in IATA 650 compliant packaging.

Biological samples transported in dry ice require additional dangerous 
goods specification for the dry-ice content.

IATA compliant courier and packaging materials should be used for 
packing and transportation and packing should be done by an IATA 
certified person, as applicable.

Samples routinely transported by road or rail are subject to local 
regulations which require that they are also packed and transported in a 
safe and appropriate way to contain any risk of infection or contamination 
by using approved couriers and packaging / containment materials at all 
times.  The IATA 650 biological sample containment standards are 
encouraged wherever possible when road or rail transport is used.

Comfortable at rest.  Ordinary physical activity 
results in fatigue, palpitation, dyspnoea (shortness 
of breath).  
III
Marked limitation of physical activity.  
Comfortable at rest.  Less than ordinary activity 
causes fatigue, palpitation, or dyspnoea.  
IV
Unable to carry on any physical activity without 
discomfort.  Symptoms of heart failure at rest.  If 
any physical activity is undertaken, discomfort 
increases.

Genetic Research
Rationale and Objectives
AstraZeneca intends to collect and store DNA for genetic research to explore how genetic 
variations may affect clinical parameters, risk and prognosis of diseases, and the response to 
medications.  Genetic research may lead to better understanding of diseases, better diagnosis 
of diseases or other improvements in health care and to the discovery of new diagnostics, 
treatments or medications.
In addition, collection of DNA samples from populations with well described clinical 
characteristics may lead to improvements in the design and interpretation of clinical trials and, 
possibly, to genetically guided treatment strategies.
Genetic Research Plan and Procedures 
Selection of genetic research population
Study selection record
All subjects will be asked to participate in this genetic research.  Participation is voluntary and 
if a subject declines to participate there will be no penalty or loss of benefit.  The subject will 
not be excluded from any aspect of the main study.
Inclusion criteria
For inclusion in this genetic research, subjects must fulfil all of the inclusion criteria described 
in section 3.1 of the main body of the Clinical Study Protocol and:

Provide informed consent for the genetic sampling and analyses.
Exclusion criteria
Exclusion from this genetic research may be for any of the exclusion criteria specified in 
section 3.2 of the Clinical Study Protocol or any of the following:

Previous allogeneic bone marrow transplant

Non-leukocyte depleted whole blood transfusion in 120 days of genetic 
sample collection
Discontinuation of subjects from this genetic research
Specific reasons for discontinuing a subject from this genetic research are:
Withdrawal of consent for genetic research: Subjects may withdraw from this genetic 
research at any time, independent of any decision concerning participation in other aspects of 
the main study.  Voluntary discontinuation will not prejudice further treatment.  Procedures 
for discontinuation are outlined in Section 5.6 of the main Clinical Study Protocol.


Clinical Study Protocol
Drug Substance Dapagliflozin
Study Code D169AC00001
Version 4.0

Collection of samples for genetic research
The blood sample for genetic research will be obtained from the subjects at Visit 2 at
randomisation.  Although DNA is stable, early sample collection is preferred to avoid 
introducing bias through excluding subjects who may withdraw due to an adverse event (AE), 
such subjects would be important to include in any genetic analysis. If for any reason the 
sample is not drawn at Visit 2, it may be taken at any visit until the last study visit. Only one 
sample should be collected per subject for genetics during the study.  Samples will be 
collected, labelled, stored and shipped as detailed in the Laboratory Manual.
Coding and storage of DNA samples
The processes adopted for the coding and storage of samples for genetic analysis are important 
to maintain subject confidentiality.  Samples will be stored for a maximum of 15 years, from 
the date of last subject last visit, after which they will be destroyed.  DNA is a finite resource 
that is used up during analyses.  Samples will be stored and used until no further analyses are 
possible or the maximum storage time has been reached.
An additional second code will be assigned to the blood sample either before or at the time of 
DNA extraction replacing the information on the sample tube.  Thereafter, the sample will be 
identifiable by the second, unique number only.  This number is used to identify the sample 
and corresponding data at the AstraZeneca genetics laboratories, or at the designated 
organization. No personal details identifying the individual will be available to any person 
(AstraZeneca employee or designated organizations working with the DNA).
The link between the subject enrolment/randomisation code and the second number will be 
maintained and stored in a secure environment, with restricted access at AstraZeneca or 
designated organizations.  The link will be used to identify the relevant DNA samples for 
analysis, facilitate correlation of genotypic results with clinical data, allow regulatory audit 
and to trace samples for destruction in the case of withdrawal of consent.
Ethical and Regulatory Requirements
The principles for ethical and regulatory requirements for the study, including this genetics 
research component, are outlined in Section 10 of the main Clinical Study Protocol.
Informed consent
The genetic component of this study is optional and the subject may participate in other 
components of the main study without participating in the genetic component.  To participate 
in the genetic component of the study the subject must sign and date both the consent form for 
the main study and the genetic component of the study.  Copies of both signed and dated 
consent forms must be given to the subject and the original filed at the study centre.  The 
Principal Investigator(s) is responsible for ensuring that consent is given freely and that the 
subject understands that they may freely discontinue from the genetic aspect of the study at 
any time.
Subject data protection
AstraZeneca will not provide individual genotype results to subjects, any insurance company, 
any employer, their family members, general physician unless required to do so by law.

Study Code D169AC00001
Version 4.0

Extra precautions are taken to preserve confidentiality and prevent genetic data being linked to 
the identity of the subject. In exceptional circumstances, however, certain individuals might 
see both the genetic data and the personal identifiers of a subject. For example, in the case of 
a medical emergency, an AstraZeneca Physician or an investigator might know a subject’s 
identity and also have access to his or her genetic data.  Also Regulatory authorities may 
require access to the relevant files, though the subject’s medical information and the genetic 
files would remain physically separate.
Data management
Any genotype data generated in this study will be stored at a secure system at AstraZeneca 
and/or designated organizations to analyse the samples.
The results from this genetic research may be reported in a separate report from the CSR or 
published in scientific journals.
AstraZeneca and its designated organisations may share summary results (such as genetic 
differences from groups of individuals with a disease) from this genetic research with other 
researchers, such as Hospitals, Academic Organization or Health Insurance Companies. This 
can be done by placing the results in scientific databases, where they can be combined with 
the results of similar studies to learn even more about health and disease. The researchers can 
only use this information for health related research purposes. Researchers may see summary 
results but they will not be able to see individual subject data or any personal identifiers.
Some or all of the clinical datasets from the main study may be merged with the genetic data 
in a suitable secure environment separate from the clinical database.
Statistical Methods and Determination of Sample Size
The number of subjects that will agree to participate in the genetic research is unknown.  It is 
therefore not possible to establish whether sufficient data will be collected to allow a formal 
statistical evaluation or whether only descriptive statistics will be generated.  A Statistical 
Analysis Plan will be prepared where appropriate.

1.2
Definitions
1.2.1
Primary analysis censoring date
The executive committee and AstraZeneca will monitor the accrual of endpoint events and 
when appropriate define the primary analysis censoring date (PACD) at which time at least
the pre-defined target number of 681 events for the primary composite endpoint is expected to 
have occurred. The study sites will be instructed to plan for study closure visits to be 
performed after PACD.
The analyses of the endpoint events will include events with onset on or prior to PACD. Event 
free patients who have not been prematurely censored due to incomplete information (see 
Sections 3.1 and 3.2) will be censored at PACD. Endpoint events with onset after PACD will 
also be adjudicated and reported descriptively.
1.2.2
Withdrawal of informed consent
Withdrawal of consent (WoC) means withdrawal from study and should only occur if the 
patient does not agree to any kind of further assessment at all.
No data after date of WoC should be collected, with the exception of vital status (dead or 
alive) at the end of the study collected from public sources, which will be included in the 
analysis of death from any cause as a sole outcome and in patient disposition summaries. Data 
collected on or prior to date of WoC will be included in analyses. 
1.2.3
Discontinuation from study drug
Discontinuation from study drug does not mean WoC. Optimally, patients who discontinue 
from study drug should continue study visits according to plan until study closure.
Alternatively, if the patient does not agree to this approach, modified follow-up should be 
arranged. Data from patients who did not withdraw consent will be included in the ITT

CONFIDENTIAL AND PROPRIETARY
12 of 29
analyses irrespective of whether the event occurred before or following discontinuation of 
study drug. 
1.2.4
Vital status
Known vital status at the end of the study will be defined when the patient is dead or has date 
last know alive on or after the PACD.
For patients who have withdrawn consent, the investigator will attempt to collect vital status 
from publicly available sources at study closure in compliance with local privacy 
laws/practices.
1.2.5
Lost to follow-up
The term lost to follow-up (LTFU) will be limited to patients with unknown vital status at the 
end of the study as defined in Section 1.2.4. Other measures will be used to describe 
incomplete follow-up of the primary endpoint (Section 4.1.5).
1.3
Study design
This is an international, multicentre, event-driven, randomized, double-blind, parallel-group,
placebo-controlled study, evaluating the effect of dapagliflozin 10 mg versus placebo, given
once daily in addition to standard of care, to prevent the progression of CKD or CV/renal
death.
It is estimated that approximately 10000 patients at approximately 450 study sites in
approximately 20 countries will be enrolled to reach the target of approximately 4000 
randomized patients.
The anticipated duration of the study is approximately 45 months. The study closure
procedures will be initiated when the predetermined number of confirmed primary endpoints
is predicted to have occurred (n=681), ie, the study end date (SED) (see Figure 1). This date, 
which in the CSP is termed study end date (SED), will be the common censoring date for 
efficacy time-to-event analyses. Thus, it will in this SAP be termed the primary analysis 
censoring date (PACD).

Study flow chart
1.3.1
Randomization
Patients will be randomized 1:1 to either dapagliflozin 10 mg or placebo. Randomization will 
be stratified by:

T2D status (with or without) at visit 1

UACR  [200,1000] or [1001,5000] mg/g  at visit 1
T2D is defined as established diagnosis of T2D or HbA1c more or equal to 6.5% (48 
mmol/mol) shown at central laboratory test at enrolment (visit 1).
Randomization will be performed in balanced blocks of fixed size. The randomization codes 
will be computer generated and loaded into the IxRS database. 
Capping
Randomization of patients based on geographic region will be monitored to ensure a global
representation. Also, the proportion of patients not on ACE-I or ARB at randomization, due to 
intolerance, will be monitored to ensure that the target population is reflected in regard to
background therapy.
The number of randomized patients with and without T2D will be monitored in order to
ensure a minimum of 30% in each sub-population. Randomization may be capped in IxRS
(ie, no more patients in a specific sub-population can be randomized) if the pre-determined
limit is reached.
The number of patients with eGFR 60 to 75 mL/min/1.73m2at the time of randomization,
shown with a laboratory test at enrolment (visit 1), will be monitored and randomization in

Study Code D169AC00001

IxRS may be capped to ensure that the number of patients in this sub-population does not
exceed approximately 10%.
1.4
Number of patients
The primary objective of the study is to determine the superiority of dapagliflozin versus
placebo in reducing the incidence of the primary composite endpoint. 
Assuming a true hazard ratio of 0.78 between dapagliflozin and placebo, using a one-sided 
alpha of 2.5%, 681 primary endpoints will provide a statistical power of 90% for the test of
the primary composite endpoint. This is based on an overall 1:1 allocation between 
dapagliflozin and placebo. The assumed hazard ratio of 0.78 is considered as clinically 
relevant and has taken into account the renal outcomes in the EMPA-REG Outcome trial.
With an annual event rate of 7.5% in the placebo treatment group, 4000 patients are estimated
to provide the required number of primary events, based on an anticipated recruitment period
of 24 months and an average follow-up period of approximately 33 months. The assumed 
placebo event rate of 7.5% is based on a review of published data in the CKD population. The 
number of patients with incomplete follow-up of endpoints is expected to be small; hence, 
these are not considered in the determination of the sample size.
2.
ANALYSIS SETS
2.1
Definition of analysis sets
2.1.1
Full analysis set 
All patients who have been randomized to study treatment will be included in the full analysis
set (FAS) irrespective of their protocol adherence and continued participation in the study.
Patients will be analysed according to their randomized IP assignment, irrespective of the
treatment actually received. The FAS will be considered the primary analysis set for the
primary and secondary variables and for the exploratory efficacy variables. 
2.1.2
Safety analysis set
All randomized patients who receive at least one dose of randomized treatment will be 
included in the safety population. Patients will be analyzed according to the treatment actually 
received. For any patients given incorrect treatment, ie randomized to one of the treatment 
groups but actually given the other treatment, the treatment group will be allocated as follows:
Patients who got both incorrect and correct treatment will be analyzed according to their 
randomized treatment. Patients who got only the incorrect treatment will be analyzed 
according to that treatment.
The Safety analysis set will be considered the primary analysis set for all safety variables.

2.2
Violations and deviations
The important protocol deviations listed below will be summarised by randomized treatment 
group

Patients who were randomized but did not meet inclusion and exclusion criteria

Patients who received the wrong study treatment at any time during the study.

Patients who received prohibited concomitant medication
As the primary analysis is intention-to-treat analysis, protocol deviation will not imply 
exclusion from analysis.
3.
PRIMARY AND SECONDARY VARIABLES
Potential endpoint events and event dates will be adjudicated by an independent clinical event 
adjudication (CEA) committee. The eGFR events will not be adjudicated. The committee 
members will not have access to the treatment codes for any patient. The CEA procedures and 
event definitions will be described in the CEA charter.
The primary and secondary efficacy variables will only include confirmed or adjudicated
events (referred to collectively as ‘confirmed events’ hereafter). Death after WoC which will 
be based on eCRF data.
All confirmed events from randomization until WoC or PACD will be included in the analysis 
of primary and secondary endpoints, except for the analysis of all-cause death as a sole 
outcome, which also will include deaths (not adjudicated) after WoC, but on or before PACD.
For analysis of time to first event, data will be expressed as two variables:

A binary variable indicating if the event in question occurred or the patient was 
censored.

An integer variable for the number of days from randomization to the first occurrence 
of an event (start date of the event – randomization date + 1), or for event free patients, 
from randomization to censoring (censoring date – randomization date + 1).
Event free patients will be censored as described below for each respective endpoint.
3.1
Primary variable
The primary efficacy variable is time from randomization to the first occurrence of any event
in the composite of  ≥50% sustained decline in eGFR from baseline, reaching end stage renal
disease (ESRD), renal death or an CV death. 
ESRD is defined as any of the following components:


Statistical Analysis Plan 
Study Code D169AC00001
Edition Number 2.0
Date 15 April 2020
CONFIDENTIAL AND PROPRIETARY
16 of 29

Sustained eGFR<15mL/min/1.72m2

Chronic dialysis

Receiving a renal transplant
Sustained eGFR decline of ≥50% from baseline and sustained eGFR <15 ml/min/1.73m2 will 
be based on two consecutive central laboratory values at least 28 days apart below the 
respective limit. The start date of the event is the date of the first of the two qualifying 
consecutive central laboratory values. Thus, the analysis will include eGFR events with onset 
prior to PACD that are confirmed after PACD, in addition to those eGFR events confirmed 
prior to PACD. These two types of eGFR events will be derived programmatically.
Chronic dialysis will be adjudicated as dialysis treatment ongoing for at least 28 days, or when
the ESRD is deemed irreversible and the dialysis treatment was stopped before day 28.
Similar to the eGFR events, the onset date of chronic dialysis will be the date when the 
qualifying dialysis treatment started.
Receiving a renal transplant and renal death will be independently adjudicated as defined in 
the CEA charter. 
Deaths adjudicated as ‘cause undetermined’ with regard to CV death or non-CV death will be 
included in the analyses as CV deaths but will not be considered as renal deaths.
Patients who do not have an endpoint event will be censored at the earliest of date of WoC or
non-CV death or non-renal death when applicable, and otherwise at the earliest of date of last 
clinical event assessment and PACD. Clinical event assessment will be captured by the 
question for potential renal events on the eCRF event assessment page. The earliest 
assessment date among components will be used as the censoring date. For example, for the 
last clinical event assessment, if the central laboratory eGFR assessment is not done in 
conjunction with the assessment of dialysis and renal transplant, the date of last available 
central laboratory eGFR measurement will be used as the censoring date.
3.2
Secondary variables
The secondary endpoints are included in a hierarchical testing sequence following the primary 
endpoint as ordered in Section 3.2.1–3.2.3
3.2.1
The composite of ≥50% sustained decline in eGFR, end stage renal disease and 
renal death
The efficacy variable is time from randomization to the first occurrence of any event in the 
composite of  ≥50% sustained decline in eGFR, reaching end stage renal disease (ESRD) and 
renal death (as defined in 3.1).

CONFIDENTIAL AND PROPRIETARY
17 of 29
All components of the composite endpoint will be defined in the same way as the primary
endpoint (see Section 3.1 for more details).
Deaths adjudicated with ‘undetermined’ cause will not be considered as renal death.
Patients who do not have an endpoint event will be censored at the earliest of date of WoC
and non-renal death when applicable, and otherwise at the earliest of date of last clinical event 
assessment and PACD. Clinical event assessment will be captured by the questions for 
potential renal events on the eCRF event assessment page. Full assessment of the composite 
endpoint requires a central laboratory eGFR value taken on the visit.
3.2.2
The composite of CV death and hospitalisation of heart failure
The efficacy variable is time from randomization to the first occurrence of any event in the 
composite of CV Death and hospitalization for HF.
Definition of CV death and hospitalisation of heart failure is described in CEA charter. Deaths 
adjudicated as ‘cause undetermined’ with regard to CV death or non-CV death will be 
included in the analyses as CV deaths. 
Patients who do not have an endpoint event will be censored at the earliest of date of WoC
and non-CV death when applicable, and otherwise at the earliest of date of last clinical event 
assessment and PACD.
Deaths adjudicated as ‘cause undetermined’ with regard to CV death or non-CV death will be 
included in the analyses as CV deaths. Last clinical event assessment is defined as the last date 
when the event assessment question for a potential heart failure event was completed on the 
eCRF event assessment page.
3.2.3
All cause mortaility
The efficacy variable is time to from randomization to death from any cause. All deaths on or 
prior to PACD, including death after WoC will be included. Patients who are alive will be 
censored at the earliest of date last known alive and PACD.
Deaths occurring after WoC will not be adjudicated. For such events, the date of death will be 
collected only in eCRF.
3.3
Safety variables
The safety and tolerability of dapagliflozin will be evaluated from serious adverse events 
(SAEs), adverse events leading discontinuation (DAEs) of study drug, changes in 
clinical/haematology parameter and adverse events (AEs) of interest (volume depletion, renal 
events, major hypoglycaemic events, fractures, diabetic ketoacidosis AEs leading to 
amputation and AEs leading for a risk for lower limb amputations [“preceding events”]).
SAEs will be collected from time of informed consent until and including the patient’s last 
visit.

Non-serious AEs will be collected from randomization until and including the patient’s last 
visit, only if it is a DAE, an AE of interest, an AE leading to a potential endpoint or the AE is
the reason for interruption of study drug or dose reduction.
Endpoint such as deaths and HF events will not be reported to health authorities to avoid 
unnecessary unblinding of efficacy endpoints that are fulfilling the SAE criteria. If it is 
determined by the CEA committee that a potential endpoint does not meet the endpoint 
criteria, then the event will be recorded as an SAE and reported to AZ patient safety data entry
site and, if applicable, sent to health authorities.

ANALYSIS METHODS
4.1
General principles
No multiplicity adjustment will be made to confidence intervals as they will be interpreted 
descriptively and used as a measure of precision. All p-values will be unadjusted. P-values for 
variables not included in the confirmatory testing sequence, or following a non-significant test 
in the sequence will be regarded as nominal.
The primary and secondary analyses include confirmed events occurring on or prior to PACD.  
Events with onset after PACD will be tabulated.
Stratification of analyses for T2D and UACR status will be performed using the stratification 
values as entered in IxRS to determine the randomization assignment. 
T2D at baseline will be defined as established diagnosis of T2D (recorded in eCRF medical
history) or central laboratory HbA1c ≥6.5% at both visit 1 (enrollment) and visit 2
(randomization).
No hazard ratio estimates with confidence interval and p-values will be given when less than
15 events in total, both treatment groups combined.
Incomplete dates
All efforts should be made to obtain complete dates of clinical assessments and events. For 
analyses requiring complete dates, partially missing dates will be imputed based on available 
corroborating information. Absent of any additional corroborating information, partially 
missing dates will be imputed as follows: if only the year part of a date is available (YY), then 
the date will be set to YY0701. If only the year and month is available (YYMM), then the date 
will be set to YYMM15. Additional imputation rules will be defined as appropriate to ensure 
that eg, dates will not be imputed as prior to randomization, after death or end date after start 
date.
Baseline value
Baseline value is defined as the last value on or prior to date of randomization.

eGFR and UACR
Baseline eGFR and UACR will be calculate as mean of visit 1 and visit 2, in case of re-
screening and retake the mean of latest value at each of visit 1 and visit 2 on or prior to
randomization will be used.
The eGFR values will be calculated using central laboratory S-Creatinine value and take
precedence over central laboratory eGFR if any discrepancies.
The formula used for calculating eGFR in (in mL/min/1.73 m2) will be the CKD-EPI equation
(Levey at al 2009).
Study drug compliance
The percentage of study drug compliance for the overall treatment period will be derived for 
each patient based on pill counts as the number of pills taken (dispensed – returned), relative 
to the expected number of pills taken. The expected number of pills taken is defined as:
1*(date of last dose – data of first dose +1), excluding days of interruption.
Study drug compliance will be presented descriptively, including mean, median, quartiles and 
5% and 95% percentiles.
4.1.1
Estimand for primary and secondary outcomes
The primary and secondary objectives will be evaluated under the treatment policy estimand 
to reflect the effect of the initially assigned randomized study drug, irrespective of adherence 
to randomized study treatment. Specifically, the analysis will be performed for the full 
analysis set including all events that occurred on or prior to PACD, including events following 
premature discontinuation of study drug. 
4.1.2
Hypotheses
To control the overall type I error rate at 2.5% one-sided.  For the primary endpoint the 
following null hypothesis will be tested at the 2.5% one-sided significance level
H0: HR [dapagliflozin:placebo] ≥1
versus the alternative hypothesis
H1: HR [dapagliflozin:placebo] <1
The secondary endpoints included in confirmatory statistical testing using a closed testing 
procedure (Section 4.1.3) will be based one similar one-sided alternative hypothesis for the 
respective treatment difference.
4.1.3
Confirmatory testing procedure
A closed testing procedure including a pre-specified hierarchical order of the primary and 
secondary endpoints will be utilized. The Type I error will be controlled at a one-sided 0.025
level for multiplicity across primary and secondary endpoints. Statistical significance will be

assessed in the pre-specified order of the endpoints as specified in Section 1.1.1 and 1.1.2. The 
testing procedure will continue down the hierarchy if the preceding endpoint is rejected at a 
one-sided 0.025 level and will stop if the null hypothesis for the preceding endpoint is not 
rejected at a one-sided 0.025 level.
4.1.4
Presentation of time-to-event analyses
In general, summary tables of time-to-event analyses will include the number and percent of 
patients with event per treatment group, event rate, hazard ratio with 95% confidence interval 
and p-value. The event rate will be derived as the number of patients with event divided by the 
total duration of follow-up across all patients in a given group.
Kaplan-Meier (KM) estimates of the cumulative proportion of patients with events will be 
calculated and plotted per treatment group, with the number of patients at risk indicated below 
the plot at specific time points. The KM plots will be presented for all time to event analyses, 
including the individual components of the composite endpoints.
4.1.5
Vital status and follow-up of endpoints
Potential endpoints will be collected and confirmed from randomization throughout the study 
until and including the patient’s last visit. The investigator will attempt to collect vital status 
(dead or alive) at the end of the study for all patients, including vital status from publicly 
available sources for patients who have withdrawn consent, in compliance with local privacy 
laws/practices.
Known vital status at the end of the study will be defined when the patient is dead or has date 
last know alive (entered on the eCRF final status form) on or after the PACD. In patient 
disposition the number of patients who are dead, alive or with unknown vital status will be 
reported separately for patients who did/did not withdraw consent. The term lost to follow-up 
(LTFU) will be limited to only patients with unknown vital status.
Follow-up of the primary endpoint will be defined in terms of assessment as described for 
censoring in Section 3.1. Thus, a patient that is not LTFU, i.e. with known vital status, may 
have incomplete follow-up of endpoints.
Complete follow up of the primary endpoint will be defined as the patient had a primary 
endpoint event, died from non-CV death or non-renal death or had complete event assessment 
on or after the PACD.
In addition to the number and percent of patients with complete follow-up, the proportion of 
total patient time with complete follow-up will be reported per treatment group.
Patient time with complete follow-up will be defined as time from randomization until the 
earliest of first primary endpoint event, death, WoC, censoring due to incomplete event 
assessment or PACD. The denominator, representing maximum complete follow-up, will be 
the time to first primary endpoint event, death or PACD.

Analysis methods
4.2.1
Demographics and baseline characteristics
Demographic and baseline characteristics will be summarized, using frequency distributions
and summary statistics based on the FAS data set, for each treatment group as well as for all
patients combined.  No statistical test will be performed for comparison of any baseline 
measurement among treatment groups.
4.2.2
Concomitant and baseline medication
Baseline medication is defined as medication with at least one dose taken before date of 
randomization and with no stop date before date of randomization. 
Concomitant medication is defined as medications taken post randomization, irrespective of 
study drug.
The frequency of baseline and concomitant medication will be presented for the FAS per ATC 
class and treatment group.
Summaries of prohibited medication (as defined in CSP Section 7.7.2) will be presented.
4.2.3
Analysis of the primary efficacy variable
The primary variable is the time to first event included in the primary composite endpoint.  
The primary analysis will be based on the ITT principle using the FAS, including confirmed
events with onset on or prior to PACD.
In the analysis of the primary composite endpoint, treatments (dapagliflozin versus placebo) 
will be compared using a Cox proportional hazards model with a factor for treatment group, 
stratified by randomization stratification factors (T2D, UACR), and adjusting for baseline
eGFR.  The analysis will use censoring of patients without any primary event as described in 
Section 3.1 .  The Efron method for ties and p-value based on the score statistic will be used. 
The event rates, p-value, HR and 95% confidence interval will be reported.  
The contribution of each component of the primary composite endpoint to the overall 
treatment effect will be examined.  In the analysis of the components, all first event of the 
given type will be included irrespective of any preceding non-fatal composite event of a 
different type. Methods similar to those described for the primary analysis will be used to 
separately analyze the time from randomization to the first occurrence of each component in 
the composite endpoint.
Kaplan-Meier estimates of the cumulative proportion of patients with event will be calculated 
and plotted, for the composite endpoint and for the individual components.

4.2.3.1
Sensitivity analyses of the primary endpoint
Chronic dialysis
A sensitivity analysis of the primary endpoint excluding chronic dialysis events ongoing less 
than 90 days will be performed. 
Undetermined cause of death
A sensitivity analysis of the primary endpoint where deaths adjudicated as ‘undetermined’ 
cause are not included as CV deaths, but treated as censoring events, will be performed.
Missing data and informative censoring
The time-to-event analysis using the Cox regression depends on the assumption of non-
informative or ignorable censoring, corresponding to the missing-at –random assumption.
The missing data in this context are patients who are prematurely censored due to WoC, 
LTFU or otherwise incomplete follow-up of endpoints. The amount of missing data will be 
described e.g., in terms of the number of patients and patient time with incomplete follow-up 
as described in Section 4.1.5.
Patient retention and follow-up are at the forefront of study planning and conduct, and the 
amount of incomplete follow-up is expected to be small. To assess the impact of missing data 
and the robustness of the results with regard to the assumption of non-informative censoring, 
sensitivity analysis will be planned based on the evaluation of the missing follow-up and 
discussed in relation to the observed efficacy signal. This may include analysis where 
scenarios in terms of increased risk in censored patients are explored to identify a ‘tipping 
point’ where statistical significance would be lost.
4.2.3.2
Subgroup analysis of the primary endpoint
Exploratory subgroup analyses of the primary composite endpoint will be performed for the 
characteristics listed in Table 1. The Cox proportional hazards models for subgroup analyses 
will include a factor for treatment group, stratified by randomization stratification factors 
(T2D, UACR), adjusting for baseline eGFR, and include the relevant subgroup variable and 
the interaction between treatment and the subgroup variable. In the subgroup analysis by T2D 
status (or UACR status), the variable for the specific randomization stratification factor will
be replaced by a variable based on CRF information.    
In addition to the number and percent of patients with event, event rate estimate, HR with 
95% confidence interval and p-value for each subgroup, the interaction p-value will be 
presented. HRs with confidence interval will be presented in a forest plot, also including the 
event rate and interaction p-value. The p-values for the subgroup analyses and interaction will 
not be adjusted for multiple comparisons as the tests are exploratory and will be interpreted 
descriptively.

Analysis of the secondary efficacy variables
The time-to-event secondary variables will be analysed in the similar manner as the primary 
variable.  That is, using a Cox proportional hazards model with a factor for treatment group, 
stratified by randomization stratification factors (T2D, UACR), and adjusting for baseline
eGFR. Censoring is described in Section 3.2 for each endpoint.
Subgroup analysis for the secondary endpoints will be conducted in the same way as the 
subgroup analysis for the primary endpoint (Section 4.2.3.2).
4.2.5
Analysis of safety variables
For safety analyses, all summaries will be based on the safety analysis set (see Section 2.1.2).
The total exposure to study drug will be defined as the length of period on study drug, 
calculated for each patient as date of last dose – data of first dose +1.

An alternative measure where days of interruption are removed will be calculated and termed 
actual exposure.
Total and actual exposure will be presented descriptively.
The on-treatment period will include events with an onset date on or after first dose of 
randomized study drug and on or before 30 days after last dose of study drug.
Additional presentations will include all events with onset on or after first dose of study drug
regardless of whether patients are on or off study treatment at the time of the event (the ‘on 
+off ‘ treatment period.). For fractures and amputations on+off treatment periods will be
considered the primary approach, while the on-treatment period will be used as primary
approach for other AEs of interest.
4.2.5.1
Adverse events 
Summaries of AEs will primarily be based on the on-treatment period. 
In addition to SAEs, the collection of AEs that are not serious is limited to DAEs, AEs leading 
to interruption of IP or dose reduction and AEs of interest (see CSP 6.3.2). Thus, summaries 
of AEs will be limited to these categories and general summaries of all AEs are not planned.
AEs will be classified according to MedDRA by the medical coding team at AstraZeneca data 
management centre, using the most current version of MedDRA possible.
Summary table of the total number and percent and patients in AE categories per treatment 
group will be provided as well as summaries by SOC and PT levels on relevant AE category.
No statistical tests to compare crude AE frequencies between treatment groups will be 
performed.
4.2.5.2
Serious adverse events
SAEs will be presented as described below both on treatment and on+off treatment.
The number and percent of patients with SAEs will be presented by SOC, PT and treatment 
group. The most common SAEs will also be presented by PT only. 
AEs with outcome death will be presented separately by SOC and PT.
4.2.5.3
Adverse events leading to discontinuation, interruption or dose reduction 
The number and percent of patients will be presented by SOC and PT for AEs leading 
discontinuation, AEs leading to temporary interruption and dose reduction (separately for each 
of the three categories based action taken “Drug Permanently Discontinued”, “Drug 
Interrupted” and “Drug Reduced” respectively).

4.2.5.4
Adverse events of interest
Each category of AEs of interest will be presented separately. AEs of interest fall in the 
categories volume depletion, renal events, major hypoglycaemic events, fractures, diabetic 
ketoacidosis and AEs leading to amputation. 
For each AE of interest a summary table including the number of percent of patients with any 
event in the AE category, SAE, DAE, AE leading to interruption and dose reduction. Each AE 
of interest category will also be tabulated with frequency by SOC and PT. 
In addition to presentations of the number of patients with event, the total number of events 
counting multiple events per patient will be presented for AE of special interest, where 
relevant eg for major hypoglycaemic events.
4.2.5.5
Laboratory Evaluation
All summaries of clinical chemistry/haematology parameters will be based on samples 
analyzed at the central laboratory, and presented in SI units.
The result and the change from baseline of each clinical chemistry/haematology tests, 
including eGFR and creatinine clearance, will be summarized by treatment group at each 
scheduled visit using descriptive statistics, including n, mean, SD, median and quartiles.
Doubling of serum creatinine
Serum creatinine will be collected and change from last value will be calculated from lab and 
adjudicated when potential doubling. Doubling of serum creatinine will be summarized by 
treatment group.
4.2.5.6
Marked laboratory abnormalities
The number and percent of patients with a marked abnormality in clinical laboratory tests will 
be summarized over time by treatment group.
Laboratory abnormalities will be evaluated based on marked abnormality (MA) criteria. The
list of MAs is provided in Appendix A. 
An on-treatment value will be considered an MA if either

the on-treatment value is beyond an MA limit AND the baseline value is not beyond 
the same limit,
OR

both the baseline and on-treatment value are beyond the same MA limit AND the on-
treatment values is more extreme (farther from the limit) than was the baseline
Laboratory MAs occurring during the on-treatment period will be summarized by treatment 
group. The directions of changes (high or low) in MAs will be indicated in the tables. 
Additionally, for each patient with a MA for a parameter, all the patient’s values of that 
parameter over the treatment period will be listed.

Vital signs
Vital signs will be presented descriptively by treatment group.
4.2.6
Analysis of exploratory objectives
The analysis of the exploratory variables will in the same fashion as the primary and 
secondary efficacy variables be based on the ITT principle, including data irrespective of 
whether the patient has discontinued study drug.
The following time to event endpoints will be analysed with the same methods as the primary 
endpoint:

Sustained eGFR decline from baseline (≥30% and ≥40%), as described in Section 3.1

Composite of chronic dialysis, renal transplant and renal death MI

Stroke

First occurrences of serum potassium falling above/below defined thresholds

Doubling of S-Creatinine
Change in eGFR over time
Change in eGFR from baseline to end of treatment will be analyzed as eGFR total slope while 
change in eGFR from day 14, i.e., the first on treatment measurement, to end of treatment will 
be analyzed as eGFR chronic slope.    
The changes in eGFR will be analyzed using a two-slope mixed effects linear spline model 
based on restricted maximum likelihood (REML) estimation, with day 14 visit defined as the 
‘knot’ in the model. The model will include fixed, categorical effects of treatment and 
stratification factors and fixed continuous covariates of baseline eGFR, time, and treatment-
by-time interaction. The intercept, acute slope (baseline to day 14 visit), and chronic slope 
(day 14 visit to end of treatment) will be included as random effects to account for variation in 
progression rates over time. An unstructured covariance will be used to model the within-
patient errors. The time variable represents the duration from baseline to each eGFR 
assessment during acute and chronic phases. This model will include all observed on-
treatment eGFR measurements (Vonesh et al 2019). 
Linear contrasts will be constructed to estimate the acute, chronic and total slope in eGFR. LS 
means of the treatment different with 95% confidence interval and corresponding two-sided p-
value will be presented. The total slope will be estimated at 30 months after baseline, in 
consideration of the anticipated data availability and duration of treatment.

The adjusted LS mean of eGFR change from baseline at each visit, based on a repeated 
measures model, will be plotted over time by treatment group to depict the pattern of eGFR 
over time.
Analysis of repeated measures
Changes from baseline over time for eGFR, UACR, HbA1c, body weight, systolic BP,
KDQOL-36 and EQ-5D-5L will be analysed with a repeated measures method. The model 
will include terms for treatment group, visit, visit*treatment group and baseline measurement 
as a covariate. All non-missing visit data will be used, including measurements after 
discontinuation of study drug. The analysis of HbA1c will be limited to patients with T2D at 
baseline.  The analysis of UACR will use log transformed values. The model will be used to 
derive a least squares estimate of the treatment difference with 95% confidence interval and 
corresponding two-sided p-value. Missing data will not be imputed.
Analysis of proportions
The proportion of patients with new T2D diagnosis during study will be analyzed by a logistic 
regression with treatment group and baseline HbA1c.  The proportion of patients entering 
CKD4 during study will be analyzed by a logistic regression with treatment group and 
baseline eGFR.  The odds ratio between treatment groups and its 95% confidence interval and 
corresponding two-sided p-value will be presented.

APPENDIX
Appendix A
Laboratory Abnormality Criteria
Table 2 provides the criteria for assessing marked abnormalities in safety laboratory 
parameters.  When there is more than one limit for a variable in Table 2, summaries will be 
provided for each limit.
If both the baseline and on-treatment values of a parameter are beyond the same MA limit for 
that parameter, then the on-treatment value will be considered a MA only if it is more extreme 
(farther from the limit) than was the baseline value. 
The following three criteria will also be summarized by treatment group in examination of the 
elevated AT (ALT and/or AST) and total bilirubin:

(AST or ALT > 3XULN) and (Total Bilirubin > 1.5XULN within 14 days on or 
after AT elevation)

(AST or ALT > 3XULN) and (Total Bilirubin > 2XULN within 14 days on or after
AT elevation)

(AST or ALT > 3XULN) and {(Total Bilirubin > 2XULN and no ALP ≥2XULN) 
within 14 days on or after AT elevation}
