Study objectives
The primary objective of this study is to:

Demonstrate whether, in addition to standard of care (SoC), 
finerenone is superior to placebo in delaying the progression of 
kidney disease, as measured by the composite endpoint of time to first 
occurrence of kidney failure, a sustained decrease of eGFR ≥ 40% from 
baseline over at least 4 weeks or renal death 
The secondary objectives of this study are to determine whether, in addition 
to SoC, finerenone compared to placebo:

Delays the time to first occurrence of the following composite endpoint: 
cardiovascular (CV) death or non-fatal CV events 
(i.e. non-fatal myocardial infarction, non-fatal stroke, hospitalization for 
heart failure [HF])

Delays the time to all-cause mortality

Delays the time to all-cause hospitalizations

Change in UACR from baseline to Month 4

Delays the time to first occurrence of the following composite endpoint:
onset of kidney failure, a sustained decrease in eGFR of ≥57% from 
baseline over at least 4 weeks or renal death.

Study design
Randomized, double-blind, placebo-controlled, parallel-group, multicenter, 
event-driven
Methodology
Randomized subjects will be treated with finerenone or placebo OD in a 
blinded fashion.  The starting dose of study drug will depend on the subject’s 
eGFR level at the Screening Visit: a lower dose of 10 mg OD if eGFR was 
                                                
1
High albuminuria (previously known as ‘micro-albuminuria’) is defined as 300 mg/g > UACR  ≥ 30mg/g in 2 out of 3 first 
morning void samples.
2
Very high albuminuria (previously known as ‘macro-albuminuria’) is defined as UACR  ≥ 300mg/g in 2 out of 3 first 
morning void samples.

between 25 to < 60 mL/min/1.73m², or the higher (target) dose of 20 mg OD if 
eGFR was ≥60 mL/min/1.73m².  Study drug may be up-titrated from Visit 2 
(Month1) onwards provided potassium is ≤4.8 mmol/L and eGFR decrease is 
less than 30% below the value last measured.  Down-titration or interruption of 
study drug is permitted at any time during the study for safety reasons.
Type of control
Placebo
Data Monitoring Committee
Yes
Number of subjects
Planned 9600 subjects screened, 4800 subjects randomized to achieve 
approximately 1068 primary efficacy events
Primary variable
Time to first occurrence of the composite endpoint of onset of kidney failure, 
a sustained decrease of eGFR ≥ 40% from baseline over at least 4 weeks,
or renal death
Time point/frame of 
measurement for 
primary variables
Events for inclusion in the primary variable (above) will be counted from the 
day of randomization (Visit 1) onwards until the End-of-Study (EOS) visit 
following the study termination decision.  In the case of premature termination 
from the study with no subsequent follow-up information, events will be 
counted up to the day of premature termination
Plan for statistical analysis
The log-rank test for the difference of the survival function of finerenone 
compared to placebo, stratified by the stratification factors region, type of 
albuminuria and eGFR category will be used, an overall two-sided significance 
level of 5.0% or 3.333% if the CV composite endpoint is not statistically 
significant according to the weighted Bonferoni-Holm procedure, with a small 
adjustment for an interim analysis

Protocol amendment summary of changes
Amendment 4 (26 FEB 2019)
This amendment is considered to be nonsubstantial based on the criteria set forth in Article 
10(a) of Directive 2001/20/EC of the European Parliament and the Council of the European 
Union because it neither significantly impacts the safety or physical/mental integrity of 
participants nor the scientific value of the study.
Overall Rationale for the Amendment:
This amendment summarizes minor changes in the conduct of the study and planned analyses. 
The main change is that the PT Visit will be performed as a telephone contact for all patients 
except those participating in the iohexol clearance sub-study. The PT Visit is to be performed 
within 4 weeks + 5 days after last study drug intake for those patients still on treatment at the 
EOS Visit (Sections 9.1, 9.2.10, and 9.2.11). The rationale for the change is that a telephone 
call is considered adequate to inquire about possible AEs and concomitant medication usage. 
This change neither compromises patient safety nor scientific value. The performance as a 
telephone contact will minimize the burden on patients, sites, and the sponsor. Procedures that 
would require the presence of the patient at the study site have been adapted accordingly. The 
following activities will no longer be performed: physical examination, ECG, recording of 
body weight and vital signs, and laboratory sampling.
All other minor changes with their brief rationale are summarized in the table below.

Section number 
and name
Description of change
Brief rationale
10.1 General 
considerations
10.3.2 Treatment 
duration, extent 
of exposure, up-
titration status 
and compliance
Specification of baseline values.
This was added to clarify the handling of 
subjects who did not immediately start 
with study drug treatment at 
randomization, because all analyses 
follow the intent-to-treat principle.
10.1 General 
considerations
10.3.3.2 Primary 
efficacy variable: 
supportive
For on-treatment efficacy 
analyses, the time window after 
last study drug administration is 
increased from 3 to 30 days.
The time window was increased to better 
reflect the more protracted nature of the 
development and diagnosis of clinical 
outcome events of interest in relation to 
treatment exposure.

Section number 
and name
Description of change
Brief rationale
10.3.4
Provision of more precise 
wording about the type of 
discontinuation.
Considering the nature of the underlying 
disease and the long duration of the 
study, it is the impact of permanent 
discontinuation of the study drug that is of 
particular interest.
10.3.4.1 Adverse 
events
New definition of treatment-
emergent AEs.
The definition of TEAEs was specified to 
account for permitted study drug 
interruptions (i.e. temporary 
discontinuations) which may occur over 
extended periods.
10.3.4.2 Laboratory 
data
Specification regarding 
interruption of study treatment.
This was updated to consider treatment 
interruptions in a similar manner as done 
for the AE presentation.
10.3.3.5.2 
Decrease in 
eGFR
10.3.4.2 Laboratory 
data
Deletion of the following 
analyses:

Absolute value of serum 
potassium >5.0 mmol/L

Relative decrease from 
baseline in eGFR of ≥25%

Increase from baseline in 
serum creatinine >0.3 mg/dL 
and >0.5 mg/dL
Patients remain on study drug treatment
with potassium values up to 5.5 mmol/L. 
Safety specific information will be 
obtained by analyzing the remaining 
thresholds of >5.5 mmol/L (moderate 
hyperkalemia) and >6.0 mmol/L (severe 
hyperkalemia) for serum potassium.
In this long-term trial relative eGFR 
decrease from baseline ≥25% does not 
provide clinically relevant information. The 
same applies to analyses of change in 
serum creatinine, which is already 
incorporated in the currently planned 
analyses of change in eGFR.
Throughout Section 
10 Statistical 
methods and 
determination of 
sample size
More precise wording.
Specifications changed for correctness.
Where applicable
Minor editorial and typographical 
errors, updated information on 
responsible persons.
Unsubstantial changes for correctness.
Abbreviations: AE = adverse event; eGFR = estimated glomerular filtration rate; TEAE = treatment-emergent
adverse event

Introduction
3.1
Background
Diabetic kidney disease (DKD) is the most frequent cause of end-stage renal disease (ESRD) 
in western countries (1). In addition, the risk of cardiovascular (CV) disease and death 
increases in patients with DKD with decreasing glomerular filtration rate (GFR) and 
increasing albuminuria levels (2, 3).
As the type 2 diabetes mellitus (T2DM) population rapidly grows throughout the world within 
the next years (4), and with it the DKD population, there is an increasing need for new 
therapeutic agents that effectively target underlying disease mechanisms and slow or halt the 
progression of kidney disease, whilst also addressing the high CV morbidity and mortality in 
this population.
DKD is a clinical syndrome affecting individuals with diabetes that is characterized by 
albuminuria on at least 2 occasions separated by 3 to 6 months (5). DKD is usually 
accompanied by hypertension, progressive rise in proteinuria, and decline in renal function (3). 
DKD is categorized based on the level of urinary albumin excretion (UAE), either 
high albuminuria (formerly micro-albuminuria, urinary albumin-to-creatinine ratio [UACR] 
30 to < 300 mg/g) or very high albuminuria (formerly macro-albuminuria, UACR ≥ 300 mg/g).
As indicated in Figure 3–1, increased UAE and decreased GFR are both associated with a 
worse prognosis, with an increase in all-cause and CV mortality. Additionally, increased UAE 
and decreased GFR are also risk factors for ESRD, acute kidney injury and progressive CKD, 
independent of each other and of other cardiovascular disease (CVD) risk factors in general as 
well as in high-risk populations (2, 6, 7).
Figure 3–1
Prognosis of CKD by GFR and albuminuria category (3)
Interventions to improve outcomes related to DKD focus on reducing risk (Figure 3–2), 
including counseling on lifestyle modifications (i.e. smoking cessation and dietary 
GFR = glomerular filtration rate.

modifications to reduce proteinuria and aid in weight loss) and interventions aimed at 
glycemic control, dyslipidemia, and hypertension (8).
Figure 3–2
Approaches to improving outcomes related to DKD (8)
Treatment with renin-angiotensin system (RAS) inhibitors has been of particular interest 
given the ability of these drugs to reduce the rate of progression of renal disease, 
independently and in addition to their antihypertensive effects, as evidenced in the Heart 
Outcomes Prevention Evaluation (HOPE) trial (9), the Reduction of Endpoints in NIDDM 
with the Angiotensin II Antagonist Losartan (RENAAL) trial (10), and the Irbesartan DN 
Trial (IDNT) (11). 
Therefore, angiotensin-converting-enzyme inhibitors (ACEIs) and angiotensin-receptor 
blockers (ARBs) can be considered as standard of care (SoC) therapy in patients with DKD 
and are often prescribed to patients with DKD at early stages (8). However, they slow but 
neither halt nor reverse kidney disease progression (12). 
In addition, in placebo controlled studies in patients with early DKD (i.e. patients with high 
albuminuria at baseline), only ACEIs were found to significantly reduce the risk of all-cause 
and CV mortality and morbidity (9). In patients with advanced DKD (i.e. patients with 
decreased kidney function and very high albuminuria at baseline) an impact on overall 
survival has not yet been demonstrated with ARBs (10, 11). ACEIs have not been 
investigated in outcome studies in the advanced DKD population yet. 
Animal studies have shown that aldosterone has an independent role in the development of 
hypertensive kidney disease and vascular injury resulting in myocardial and renal fibrosis 
(Figure 3–3) and its blockade reduces proteinuria (13-16). Long-term RAS blockade with 
ACEIs and ARBs results in incomplete suppression of serum aldosterone levels and is known 
as the ‘aldosterone escape’ phenomenon (17). Exploratory clinical studies in adults have 
shown that in adults with CKD exhibiting the ‘aldosterone escape’ phenomenon, treatment 
with mineralocorticoid-receptor antagonists (MRAs) improves kidney outcomes such as 
proteinuria (18). However, there is also evidence for possible therapeutic utility of 
CVD = cardiovascular disease; ESRD = end-stage renal disease;
RAAS = renin-angiotensin-aldosterone system.

mineralocorticoid receptor (MR) blockade in conditions of tissue and organ damage with 
normal aldosterone levels (19).
Figure 3–3
Mechanisms of cardiac and renal damage induced by aldosterone 
excess (20)
The results of several short-term studies support the proposal of Shavit et al. that aldosterone 
should be considered a novel therapeutic renal target in CKD patients with the added potential 
‘off-target’ effects on heart and vasculature (21). Nevertheless, large-scale, long-term 
outcome trials examining whether MRAs can slow progression of kidney disease or prevent 
CV events in this population are missing.
Moreover, the use of currently available steroidal MRAs is known to increase the risk of 
hyperkalemia, particularly in patients with T2DM and decreased kidney function (20, 22).
Finerenone (BAY 94-8862) is a next-generation, oral, selective, non-steroidal MRA. In 
animal models, finerenone reduced cardiac and renal hypertrophy, plasma prohormone of 
brain natriuretic peptide (BNP) and proteinuria more efficiently than in those treated with the 
steroidal MRA eplerenone, when comparing equi-natriuretic doses.  Finerenone’s tissue 
distribution pattern in rats was found to differ from the steroidal MRAs, i.e. spironolactone 
and eplerenone, which showed a higher accumulation of the drug equivalent concentration in 
kidney than in heart tissue, in contrast to finerenone which was found to be equally distributed 
in both the kidney and heart tissue (23).  Steroidal MRAs are known to interfere with the 
steroid hormone receptor, which can cause sexual side effects such as gynecomastia in men.  
However, finerenone is a non-steroidal and selective MRA in vitro, without any detectable 
affinity for the related androgen receptor; sexual side effects are therefore not expected to 
occur with finerenone at therapeutic dose levels.  These characteristics may translate to a drug 
with a positive benefit-risk ratio in patients with DKD.
In a Phase IIa study, finerenone was studied in individuals with stable HFrEF and mild (eGFR 
60 to < 90 mL/min/1.73 m2) -to-moderate (30–60 mL/min/ 1.73 m2) CKD. In this

minerAlocorticoid Receptor Antagonist Tolerability Study (ARTS; IMPACT No. 14563, 
NCT01345656), finerenone doses of 2.5 to 10 mg/day safely reduced albuminuria and doses 
of 5.0–10.0 mg/day reduced plasma natriuretic peptides levels to the same magnitude as 
spironolactone 25–50 mg/day. All doses of finerenone were associated with a statistically 
significantly smaller mean increase in serum potassium concentration and clinically 
significantly smaller decreases in eGFR compared to spironolactone (24). 
The MinerAlocorticoid Receptor Antagonist Tolerability Study-Diabetic Nephropathy 
(ARTS-DN; IMPACT No. 16243; NCT01874431) was a multicentre, randomized, 
double-blind, placebo-controlled, parallel-group, Phase IIb study investigating the safety and 
efficacy of several oral doses of finerenone in patients with T2DM and a clinical diagnosis of 
DKD, based on either high albuminuria (UACR 30 to 299 mg/g) or very high albuminuria 
(UACR 300 to 3000 mg/g), and with an estimated glomerular filtration rate (eGFR) of 
30 mL/min/1.73 m2 or more. Finerenone doses of 1.25 mg up to 20 mg once daily (OD) were 
investigated in 823 randomized patients over 90 days of treatment compared to placebo in 
addition to SoC, including a RAS-inhibitor. Finerenone statistically significantly reduced 
albuminuria by 21 to 38%, compared to placebo, at doses of 7.5 mg to 20 mg OD when added 
to RAS blockade. All doses of finerenone were safe and well-tolerated. Incidences of 
treatment-emergent adverse events (TEAEs) were similar between placebo and all finerenone 
dose groups.
Based on the aforementioned properties and initial results of finerenone in Phase II clinical 
trials, finerenone has the potential to address the unmet medical needs in patients with the 
clinical diagnosis of DKD. When added to SoC therapy including a RAS blocker, 10 or 20mg 
finerenone given OD might demonstrate a reduction of CV mortality and morbidity and also 
delay the progression of renal disease compared to placebo in addition to SoC. 
Further details can be found in the latest available version of the Investigator’s Brochure (IB), 
which contains comprehensive information on the study drug.
In this study (16244), finerenone will be investigated in patients at high risk of progressing to 
kidney failure and at high risk of CV events.  A second study of the Phase III program of 
finerenone in DKD, Study 17530, will investigate finerenone in patients at lower risk of 
progressing to kidney failure but still at a high-risk of developing a first or recurrent CV 
event.  Accordingly, in Study 16244, the primary endpoint will focus on renal outcomes 
whereas in Study 17530, the primary endpoint will focus on CV outcomes.

Rationale of the study
Study 16244 will be the first large-scale, long-term outcome trial examining whether the 
non-steroidal MRA finerenone can slow the progression of kidney disease in patients with the 
clinical diagnosis of DKD.  Secondary endpoints will focus on CV outcomes, all-cause 
mortality, all-cause hospitalizations and change in UACR.
The risk for CKD progression and ESRD is elevated in this population of patients with 
advanced DKD, with lower eGFR and higher levels of albuminuria being independent risk 
factors (6).
Together with Study 17530, which will be the first large-scale, long-term outcome trial 
examining whether the non-steroidal MRA finerenone can decrease CV mortality and 
morbidity in patients with the clinical diagnosis of DKD, Study 16244 is part of the Phase III 
trial program to evaluate if finerenone in addition to SoC can reduce the incidence of 
important clinical outcomes in patients with the clinical diagnosis of DKD. 
An inappropriate release of aldosterone contributes to target organ damage found in heart 
failure, myocardial infarction, chronic renal failure and hypertension. The extensive 
expression of the MR in the CV system including the heart, endothelial cells, vascular smooth 
muscle cells and kidney mesangial cells gives further evidence for the role of aldosterone in 
CV and renal injury.
Blockade of the action of aldosterone and potentially other MR ligands such as cortisol has 
been demonstrated to be of benefit in different forms of CVD (25-27).  Results from several 
short-term studies show that treatment with MRAs in addition to RAS blockade with an ACEI 
or ARB improves albuminuria; however, long-term outcome trials examining whether MRAs 
can prevent CV events or slow progression of kidney disease in a diabetic or non-diabetic 
CKD population are still lacking. The Phase III program with finerenone in DKD will be the 
first program addressing both questions: Study 16244 will investigate the effects of the 
non-steroidal MRA finerenone on renal outcomes and Study 17530 will investigate the effects 
of finerenone on CV outcomes. 
The actual mechanisms behind the pathological effects of aldosterone in DKD have not yet 
been fully elucidated; however, aldosterone seems to be a key player in the progression of 
kidney disease, and also contributes to the accompanying high CV morbidity and mortality of 
these patients. Potent and selective MR blockade with finerenone may therefore provide 
protection against the burden of CVD and also slow or halt the progression of kidney disease 
in the targeted DKD population. 
3.3
Benefit-risk assessment
Among patients with diabetes, those with kidney disease are consistently observed to have 
substantially elevated mortality rates. Much of this mortality is due to CVD, although non-CV 
mortality is also increased. Albuminuria and eGFR are independently and additively associated 
with increased risks of CV events, CV mortality, and all-cause mortality (28). There is a high 
unmet medical need for treatments that can reduce the extensive burden of CV mortality and 
morbidity and the progression of kidney disease in patients with DKD.

The population for Study 16244 has been chosen to adequately define a study population at high 
risk of developing renal events.  Meta-analyses have shown that very high albuminuria is 
associated with a 3- to 5-fold increased risk for the development of ESRD compared with those 
with normal levels of albuminuria (29, 30).  Another analysis of > 10000 individuals with T2DM 
have shown that patients with very high albuminuria and an eGFR < 60 mL/min/1.73 m2 had a 
16-fold higher risk for renal events compared to patients with neither of these risk factors (31).  
Patients with very high albuminuria and reduced eGFR have a substantially increased risk of 
subsequent renal events and rapidly progress to ESRD (6).  In patients with high albuminuria, the 
presence of diabetic retinopathy may indicate rapid loss of renal function and thus may be an 
additional predictive prognostic factor for the progression of CKD secondary to diabetes (32).
Therefore, Study 16244 will include a majority of patients with very high albuminuria and an 
eGFR< 60 mL/min/1.73 m2.  However, there are patients with advanced renal disease with 
very high albuminuria and an eGFR up to 75 mL/min/1.73m2 who may also benefit.  Patients 
with high albuminuria and a history of diabetic retinopathy have a higher risk within the 
patient population of high albuminuric patients to progress to ESRD and have therefore also 
been chosen as part of the target population for this study.
The presence of albuminuria in an individual is highly predictive of CV events and 
progression of kidney disease. In ARTS-DN (study 16243) in patients with T2DM and DKD 
treated with finerenone in combination with SoC therapy using a RAS inhibitor, a 
dose-dependent reduction in UACR from baseline to Day 90 was demonstrated.  Statistically 
significant reductions in UACR of 21%, 25%, 33% and 38% at Day 90 compared to baseline 
were observed for the 4 highest doses of finerenone (7.5, 10 mg, 15 mg, and 20 mg od, 
respectively) compared to placebo.  In a post hoc analysis, UACR decreases of ≥ 30% from 
baseline to Day 90 in the placebo, 7.5 mg, 10 mg, 15 mg and 20 mg groups were seen for 
23.9%, 40.2%, 46.0%, 51.3% and 62.5% of subjects, respectively, and UACR decreases of 
≥50% in the same groups were seen for 13.6%, 17.2%, 17.2%, 33.6% and 40.2% of subjects, 
respectively. Post-hoc analyses of randomized clinical trials (33, 34) suggest that a meaningful 
reduction in albuminuria may translate to protection from CV events and declining renal 
function in patients with diabetic and non-diabetic renal disease with albuminuria.  For every 
30% reduction in albuminuria, the risk of ESRD decreased by 23.7% (95% confidence interval, 
11.4% to 34.2%; p=0.001) (33); there was an 18% reduction in CV risk and 27% reduction in 
HF risk for every 50% reduction in albuminuria (34).
Due to finerenone’s mode of action, hyperkalemia is an important identified risk which was 
also identified from previous studies with finerenone. Patients with pre-existing impairment 
of their renal function are likely to have a greater risk of experiencing clinically significant 
hyperkalemia. A greater risk for hyperkalemia may also occur if drugs which raise the 
potassium concentration (e.g. ACEI, ARBs or potassium-sparing diuretics) are used 
concomitantly. 
Worsening of renal function has been shown to occur with the steroidal MRAs, i.e.
spironolactone and eplerenone, as well as RAS blocker in general.
The risk for such adverse events with finerenone is not ruled out.  However, in ARTS-DN, 
the incidence of hyperkalemia was low, and the incidence of eGFR decline ≥30% relative to

baseline was similar between placebo and finerenone groups, with no imbalance in reported 
AEs related to the MedDRA primary system organ class ‘Renal and urinary disorders’. In 
ARTS (study 14563), all doses of finerenone resulted in significantly lower potassium 
increase and less eGFR reduction compared to spironolactone.
Thus, potassium levels and renal function will be closely monitored in this study. 
To minimize safety risks to the patient, starting doses of study medication will be chosen 
according to baseline renal function, and subsequent dose up-titration will be performed on 
the basis of measured potassium and eGFR values.  A 2-step up-titration is consistent with 
current clinical practice to initiate treatment with a RAS blocker at a low dose, and 
to up-titrate the drug only if tolerated in order to avoid adverse effects on potassium and renal 
parameters. Stopping rules for temporary and permanent discontinuation or dose reduction of 
study drug based on potassium values will minimize the risk of hyperkalemia. At any time 
during the study, the investigator has the option to also down-titrate the study drug, depending 
on serum potassium and the progression of the underlying disease.  
All protocol-related procedures, including vital signs measurements, 12-lead electrocardiograms 
(ECGs), echocardiography and blood and urine sampling, are non-invasive or established 
routine assessments in the management of patients with DKD with or without CVD. 
The high risk for progression of kidney disease and fatal and non-fatal CV events in the study 
population of Study 16244, taken together with the beneficial results of MRAs on CVD in 
previous clinical trials and the results of finerenone in the Phase II studies all point towards a 
positive risk-benefit assessment that is in favor of the participation of subjects in this study.

Study objectives
The primary objective of this study is to:

Demonstrate whether, in addition to standard of care (SoC), finerenone is superior to 
placebo in delaying the progression of kidney disease, as measured by the 
composite endpoint of time to first occurrence of kidney failure, a sustained decrease 
of eGFR ≥ 40% from baseline over at least 4 weeks, or renal death. 
The secondary objectives of this study are to determine whether, in addition to SoC, 
finerenone compared to placebo:

Delays the time to first occurrence of the following composite endpoint:
CV death or non-fatal CV events (i.e. non-fatal myocardial infarction, non-fatal stroke, 
hospitalization for heart failure [HF])

Delays the time to all-cause mortality

Delays the time to all-cause hospitalization 

Change in UACR from baseline to Month 4

Delays the time to first occurrence of the following composite endpoint: onset of 
kidney failure, a sustained decrease of eGFR ≥57% from baseline over at least 
4 weeks, or renal death.

Study design - amended
This section was changed in Amendment 3, see Section 15.1.2.3.
Design overview
Study 16244 is a randomized, double-blind, placebo-controlled, parallel-group, multicenter, 
event-driven Phase III study. Figure 5–1 displays the overall study design.
Patients from approximately 900 study centers worldwide will be randomized in a 1:1 ratio to 
either finerenone or placebo in addition to SoC therapy. Assuming a screening failure rate of 
approximately 50%, 9600 patients will have to be screened to randomize approximately 
4800 patients. 
The anticipated duration of the study is approximately 4 years: this includes an anticipated 
recruitment period of 2.75 years followed by a study drug treatment period of 1 year after the 
enrolment of the last patient into the trial and a maximum of 4.5 months for the run-in and 
screening period and 1 month for the follow-up period. However, as an event-driven trial, the 
actual length of the trial will depend on the observed event rates, the patient recruitment rate, 
and length of the recruitment period. 
Since all randomized subjects belong to the Full Analysis Set (FAS) on which the efficacy 
analyses are based, it is important to avoid randomization of non-eligible subjects into the study. 
Run-in Period (4 up to 16 weeks)
Subjects with written informed consent who complete the Run-in Visit and meet all
eligibility3 criteria will be enrolled into a mandatory Run-in Period, the purpose of which is to 
ensure that the subject’s SoC therapy including treatment with ACEIs or ARBs is optimized 
and that all inclusion and exclusion criteria are met at the Screening Visit.  The Run-in Period 
will last for a minimum of 4 weeks and a maximum of 16 weeks.
In the absence of documentation of diagnosis of high or very high albuminuria (see Section 3.1
for definition), the subject may still be enrolled into the study as albuminuria will be 
measured at the Run-in Visit; in this case, the Run-in Period must last for a minimum of 
12 weeks and a maximum of 16 weeks.
Screening Period (up to 2 weeks)
At the end of the Run-in Period, a Screening Visit to confirm the subject’s eligibility will take 
place within ≤ 2 weeks prior to the planned randomization. At this visit, it will be assessed 
whether the subject still meets all the inclusion and none of the exclusion criteria.3
For those subjects without a prior documented diagnosis of high or very high albuminuria, the 
Screening Visit must be performed at least 12 weeks after the Run-in Visit, and albuminuria 
should then be re-evaluated. If the subject still suffers from high or very high albuminuria 
                                                
3 Eligibility criteria related to central laboratory evaluation will be assessed once results are available.

Treatment Period
Eligible subjects will be randomized to receive once daily (OD) oral doses of finerenone 
(10 mg or 20 mg) or placebo in addition to their SoC therapy.
There will be up to 4 planned visits (including randomization at Visit 1) in the first 4 months; 
thereafter visits will take place every 4 months until the end of the study. Study drug dose can 
be up-titrated from Visit 2 (Month 1) onwards or down-titrated at any point (even between 
scheduled visits); guidance on dose adjustment is provided in Section 7.4. Subjects may be 
seen at any time throughout the study, in addition to scheduled visits, at the discretion of the 
investigator.
It is planned that all randomized subjects will remain in the trial until either: 
a.
the projected number of primary endpoints (see Sections 9.4.1 and 10.4) is reached, or 
b. the trial is terminated prematurely at the recommendation of the independent Data 
Monitoring Committee (DMC) (see Section 13.1.3). 
All randomized subjects, including any subject who experienced a health event considered for 
the pre-specified primary or secondary endpoints, should continue to receive study drug until 
the trial is completed (see definition for end of study below) provided there are no safety 
grounds for discontinuing treatment.
Discontinuation of study drug (for any reason) does not constitute the subject’s withdrawal 
from the study, except if the investigator believes that it is in the best interest of the subject or 
if the subject withdraws consent (see Section 6.4.1 for details).  
Details on procedures that are important to ensure the safety of the individual study subject 
are provided in the relevant sections of this protocol (i.e. medical management, control of 
blood pressure and use of potassium supplements/lowering agents in Section 8.1, and 
monitoring blood potassium in Section 9.7.1). 
Follow-up Period
The period between the subject’s last intake of study drug and last visit in the study is referred 
to as the ‘Follow-up Period’. If a subject withdraws from study drug permanently but does 
not withdraw from the study, this would apply to the period between the Premature 
Discontinuation (PD) Visit, which should take place as soon as possible following permanent 
discontinuation of study drug, and the EOS Visit. In the case where a subject discontinues 
treatment at the EOS Visit, the Follow-up Period applies to the period between the EOS visit 
and PT visit.
All subjects who had withdrawn consent can be followed up for vital status if they do not sign 
the ‘Declaration of Objection’ form. In addition, vital status can be obtained by the 
investigator from publicly available data sources. The collection of vital status must be 
obtained within the timelines provided by Bayer.

End of study
The end of the study as a whole will be reached as soon as the last visit of the last subject of 
Study 16244 has been reached in all centers in all participating countries (EU and non-EU).
The study will terminate either when:
(1) the targeted number of primary efficacy endpoint events have been positively adjudicated
OR
(2) at a recommendation of the DMC, whichever is earlier.
After notification of study termination, for all subjects still participating in the study, 
an End-of-Study (EOS) Visit should be scheduled as soon as possible (within 4 weeks of 
notification at the latest) to determine whether the subject had an event for inclusion in the 
primary or secondary endpoints.
Subjects who are still on treatment will discontinue study drug treatment at the EOS Visit and 
must perform the Post-Treatment (PT) Visit (4 weeks + 5 days) after their last dose of study 
drug.
The primary completion event for this study is the last visit for the last subject.
The primary completion date for this study according to the FDA Amendment Act is specified 
in a separate document (not part of this study protocol).

Study population
Subjects with T2DM and a clinical diagnosis of DKD treated with the individual maximum 
tolerated labeled dose of either an ACEI or an ARB (but not both), who meet all the inclusion 
criteria and none of the exclusion criteria will be eligible for enrollment in this study. Subjects 
switching over from Study 17530 to this study at the Screening Visit must only meet all the 
inclusion criteria and none of the exclusion criteria at the Screening Visit to be eligible for 
enrollment in this study (16244).

Inclusion criteria
Subjects must meet all of the following inclusion criteria to be included in the study:
1. Written informed consent signed before any study-specific procedure
2. Men or women aged 18 years and older. The lower age limit may be higher if legally 
required in the participating country.
3. Women of childbearing potential can only be included in the study if a pregnancy test is 
negative at the Screening Visit and if they agree to use adequate contraception. Adequate 
contraception is defined as any combination of at least 2 effective methods of birth 
control, of which at least one is a physical barrier (e.g. condoms with hormonal 
contraception or implants or combined oral contraceptives, certain intrauterine devices). 
Women are considered post-menopausal and not of child-bearing potential if they have 
had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile 
(e.g. age appropriate) or 6 months of spontaneous amenorrhea with serum FSH levels 
> 40 mIU/mL [for US only: FSH levels > 40 mIU/mL and estradiol < 20 pg/mL] or have 
had surgical treatment such as bilateral tubal ligation, bilateral ovarectomy, or 
hysterectomy.
4. Subjects with type 2 diabetes mellitus as defined by the American Diabetes Association (35)
5. Subjects with a clinical diagnosis of DKD based on either of the following criteria at the 
Run-in and Screening Visit:

Persistent high albuminuria defined as UACR of 30 mg/g (3.4 mg/mmol) 
but < 300 mg/g (< 33.9 mg/mmol) in 2 out of 3 first morning void samples and 
eGFR 25 but < 60 mL/min/1.73 m2 (CKD-EPI) (36, 37) and presence of 
diabetic retinopathy in the medical history 4

in 2 out of 3 first morning void samples and eGFR ≥25 but < 75 mL/min/1.73 m2
(CKD-EPI) (36, 37) 5
Note: One re-assessment of eGFR and UACR is allowed at the Run-in Visit and the 
Screening Visit. If one of the 3 UACR measurements is missing but the other 
2 are valid, these values can be used to assess subject’s eligibility for this study.
                                                
4
Note: The number of subjects with high albuminuria and presence of diabetic retinopathy in the medical 
history will be capped at approximately 10% of the total population at screening.
5
Note: The number of subjects with eGFR ≥60 to 75 mL/min/1.73m2 and very high albuminuria will be capped 
at approximately 10% of the total population with very high albuminuria at screening.

Justification of selection criteria
The selection criteria were chosen to adequately define a DKD study population at high risk 
of progressing with their CKD towards ESRD or developing CV events, and to exclude 
subjects from the study who may potentially be exposed to particular risks after study drug 
administration and subjects with conditions that may have an impact on the aims of the study.

Withdrawal of subjects from study
6.4.1
Withdrawal
6.4.1.1
Discontinuation of study drug - amended
This section was changed in Amendment 3, see Section 15.1.2.6.
After randomization, discontinuation of study drug (for any reason) does not constitute the 
subject’s withdrawal from the study (see also Section 6.4.1.2).
Study drug must be permanently discontinued if any of the following occurs:

Pregnancy of the study subject (see also Section 9.6.2)

The investigator is of the opinion that continuation of treatment with study drug is 
harmful to the subject’s well-being

The randomization code is broken by the investigator, or other responsible person, 
when knowledge of the subject’s treatment is required

Any investigational drug other than the study drug is used.
Study drug may be permanently discontinued if any of the following occurs:

Any suspected drug-related AE or SAE

If any exclusion criterion applies during treatment

If a significant violation of the protocol occurs, as defined by the sponsor and the 
coordinating investigator.
In general, subjects who permanently discontinue study drug are expected to continue in the 
follow-up period and to attend all protocol-specified study visits, and should be encouraged to 
perform all assessments described in the visit schedule (see Section 9.2).
If a subject no longer on study drug is unable to attend the clinic for a study visit, a 
telephone consultation may be performed to determine if relevant health events /endpoints 
(e.g. development of CV or renal complications) have occurred. Ideally, a face-to-face visit 
should be performed at least once a year. Expected frequency of telephone contacts should be 
in line with the standard visit schedule, and therefore performed every 4 months. Ad hoc 
additional telephone contacts may also be requested (e.g. prior to the interim analysis) and 
made to the subject themselves or to other contact as provided by the patient, e.g. a next of 
kin, primary physician (or local equivalent).
Note that study drug may be temporarily discontinued (i.e. interrupted), as described in 
Section 7.4.

6.4.1.2
Discontinuation of study
Subjects must be withdrawn from the study if the following occurs:

At their own request or at the request of their legally acceptable representative. 
At any time during the study and without giving reasons, a subject may decline to 
participate further. The subject will not suffer any disadvantage as a result (see also 
Section 13.4).
Subjects may be withdrawn from the study if either of the following occurs:

If, in the investigator's opinion, continuation of the study would be harmful to the 
subject’s well-being 

At the specific request of the sponsor and in liaison with the investigator.
Should a subject withdraw consent to participate in the study, he/she may either:

Agree to continue releasing information for the study (for details, see Section 9.1),
or

Refuse to allow further release of information.
Depending on the time point of withdrawal: 

A subject who discontinues study participation prematurely for any reason is defined 
as ‘dropout’ if the subject has already been randomized

A subject who, for any reason (e.g. failure to satisfy the selection criteria), terminates 
the study before randomization is regarded as a ‘screening failure’.
General procedures
In all cases, the reason for withdrawal of study drug and/or of study participation must be 
recorded in the eCRF and in the subject’s medical records.
As specified in Section 13.4, the subject may object to the generation and processing of 
post-withdrawal data.
Details for the premature termination of the study as a whole (or components thereof) are 
provided in Section 12.
6.4.2
Replacement
Randomized subjects who withdraw prematurely will not be replaced.
If applicable, a subject who is not eligible at the Run-in or Screening Visit may be re-screened 
at a later time (see Section 6.4.2.1) or switch over to Study 17530 (see Section 6.4.2.2) 
provided the pre-requisites are met.

Re-screening - amended
This section was changed in Amendment 3, see Section 15.1.2.7.
If a subject is not eligible at the Run-in or Screening Visit for either this study (16244) or 
Study 17530, the subject may be re-screened at a later time.
The following conditions are pre-requisites of re-screening:

Before re-screening, new written informed consent must be obtained

Allocation of a new subject identification number 

All assessments for the study must be repeated

A minimum of 3 months between the initial Run-in Visit and re-screening.
A subject may be re-screened only once and after being declared as a screening failure.  
During re-screening, a switch over between studies is allowed (see Section 6.4.2.2).
6.4.2.2
Switch over between studies
DKD is a disease continuum characterized by 2 highly variable parameters, eGFR and UACR. 
The thresholds of these parameters for these studies (16244 and 17530) were chosen in order 
to define a high risk population.  It should be noted these parameters may vary in daily life 
making the patient eligible for one or the other study.  Nevertheless, these variations still reflect 
the disease continuum and do not alter the high risk. The reason for allowing switch over is to 
account for these intrinsic variations.  In addition, it also serves the purpose of reducing the 
burden on the subjects due to not needing to repeat the run-in and screening assessments.  
Subjects are permitted to switch from Study 16244 to Study 17530, or vice versa. 
A switch over from either study is permitted only once and should take place during the 
respective Run-in and Screening periods.
An example is as follows:
If a subject initially enrolled in Study 16244 is found to be not eligible during the Run-in 
or Screening Period of Study 16244, the investigator may consider enrolling this subject 
into Study 17530 if the subject meets the eligibility criteria at run-in or screening for 
Study 17530. Prior to the subject being enrolled in Study 17530, the subject must provide 
written informed consent.
The subject will be transferred to Study 17530 in the IxRS system as outlined in the 
Investigator Guide. The subject will continue with their originally assigned subject 
identification (SID) into Study 17530. Within the SID, the study identifier will indicate 
the subject has switched from Study 16244 to Study 17530 (see Section 6.5). The 
procedures and assessments from the Run-in and/or Screening Visit(s) of Study 16244 do 
not have to be repeated for Study 17530; the data, including laboratory data, will be 
transferred from Study 16244 to Study 17530.

If a subject switches from Study 16244 to Study 17530 in the Run-in period but is found 
not to meet the in- and exclusion criteria of Study 17530 at the end of the Screening Period,

this subject is not permitted to switch back into Study 16244 and must be registered as a 
screening failure of study 17530. If this is the case, the subject may still be re-screened for 
either of the studies if he or she fulfills the criteria mentioned in Section 6.4.2.1.
6.5
Subject identification
Upon signing the informed consent form and registering the subject in IxRS, each subject will 
automatically be assigned a unique 9 digit subject identification (SID) number by the IxRS for 
unambiguous identification throughout the study.  The SID number is constructed as follows:
Digits 1 - 2:
Unique country number
Digits 3 - 5:
Study center number, unique within any country
Digit 6:
Study-specific identifier
Digits 7 - 9:
Subject number, unique within any study center of a given country for the study.

Treatment(s)
7.1
Treatments to be administered
Finerenone immediate-release (IR) tablets are light orange film-coated tablets, oval 
(modified oblong), containing 10 mg or 20 mg finerenone (Table 7–1). Matching placebo 
tablets will be supplied.
Following a Screening Visit, eligible subjects will be randomized 1:1 to either finerenone or 
placebo, and study drug will be dispensed according to the visit schedule (see Section 9.1).
The subject will receive the following:

Finerenone
−
10 mg finerenone tablet once daily (OD)
(starting dose for subjects with an eGFR between 25 to < 60 mL/min/1.73m² 
at the Screening Visit) 
−
20 mg finerenone tablet OD
(starting dose for subjects with an eGFR ≥60 mL/min/1.73m² 
at the Screening Visit) 
or

Placebo tablet OD. 
Following randomization of the subject, the IxRS will determine the bottle number for the 
study site investigator or designee to select for the subject. The investigator at the study site is 
to instruct subjects to take 1 tablet OD, preferably in the morning. The first dose of study drug 
should be taken at the site on the same day as Visit 1 (Day 1), preferably in the morning.

Treatment assignment
Eligible subjects will be randomized within ≤2 weeks after the Screening Visit. The 
randomization will be stratified by region (North America, Europe, Asia, Latin America and 
others), type of albuminuria at screening (high or very high albuminuria) and eGFR at 
screening (25 to <45, 45 to <60, ≥60 mL/min/1.73m²). The eGFR will be calculated by the 
Central Laboratory applying the CKD-EPI formula (36).
The number of subjects with eGFR ≥60 to <75 mL/min/1.73 m2 and very high albuminuria 
will be capped at approximately 10% of the total population with very high albuminuria at 
screening. The number of subjects with high albuminuria and presence of diabetic retinopathy 
in the medical history will be capped at approximately 10% of the total population at screening.

Dosage and administration - amended
This section was changed in Amendment 3, see Section 15.1.2.8.
As shown in Table 7–2, the starting dose of finerenone will depend on the eGFR value at the 
Screening Visit.
Thus, at randomization, subjects with an eGFR between 25 to < 60 mL/min/1.73m² at the 
Screening Visit (central laboratory results) will be assigned to the lower dose of finerenone 
(10 mg) or placebo in addition to SoC, whilst subjects with an eGFR ≥60 mL/min/1.73m² will 
be assigned to the higher dose of finerenone (20 mg) or placebo in addition to SoC.

Missed intake of study drug
If the subject misses his/her scheduled daily intake of study drug, he/she should consider the 
following 2 options before continuing study drug intake:
(1) If intake of the missed tablet is discovered >8 hours before the next scheduled dose, the 
subject should take the study drug as soon as possible
(2) If the missed intake is discovered within 8 hours of the next scheduled dose, 
the subject should wait and take the next tablet at the usual time.
Up- and down-titration of study drug
The investigator is encouraged to up-titrate the dose of study drug at any time once the patient 
has been on a stable dose for 4 weeks (± 7 days) (e.g. from Visit 2 onwards for patient starting 
study drug on the lower dose) either at a regular visit or an Up-titration Visit.  Up-titration can 
be performed provided:

the potassium concentration (local laboratory value) is ≤4.8 mmol/L,
AND

eGFR decrease (local laboratory value) is less than 30% below the value measured at 
the last regular visit. 
Subjects who started with or were up-titrated to the target dose (20 mg OD) of the study drug 
but who do not tolerate this dose may be down-titrated at any point during the study, 
including between-scheduled visits if required for safety reasons. These subjects may be 
up-titrated again based on the rules provided above. If the subject is already at the lower dose, 
the study drug can be interrupted at the investigator’s discretion (refer to Section 9.7.1 for 
guidance). If the study drug is interrupted for more than 7 days, the study drug should be re-
started at the lower dose (10 mg OD).
Subsequent to an up-titration or re-start of study drug after interruption of study drug intake
for more than 7 days, the investigator should perform an Up-titration Visit 4 weeks (±7 days) 
after titration or restart, in order to monitor potassium levels and renal function (see
Table 9–1). If a regular study visit will be scheduled to take place 4 weeks (± 7 days) after up-
titration, the monitoring of potassium and renal function is assured and no Up-titration Visit 
has to be performed in addition.  With down-titrations, the unscheduled safety visit may need 
a smaller time window and should be performed at the investigator’s discretion.
At any point during study drug treatment, if blood potassium is found to be elevated, 
study drug treatment should be adjusted according to guidance provided in Section 9.7.1.
Both up- and down-titrations will be at the investigator’s discretion and will depend on the 
general clinical condition of the individual subject. The investigator should attempt to reach 
the maximum (target) dose of study drug as long as safety is not compromised.
All titrations, including the reasons for down-titration or for not dispensing the 20 mg dose, 
must be documented in the eCRF.

Blinding
7.5.1
Blinding measures
Finerenone IR tablets (10 mg and 20 mg) and placebo tablets will be identical in appearance 
(size, shape, color). The packaging and labeling will be designed to maintain the blinding of 
the investigator’s team and the subjects. The study data will remain blinded until database 
lock and authorization of data release according to standard operating procedures.
Appropriate measures will be taken to maintain blinding while bioanalysis is ongoing.
7.5.2
Unblinding - amended
This section was changed in Amendment 3, see Section 15.1.2.9.
In compliance with applicable regulations, in the event of a SUSAR (see Section 9.6.1.4) 
related to the blinded treatment, the subject’s treatment code will usually be unblinded before 
reporting to the health authorities and ethic committees.
In order to maintain the integrity of the study, SUSARs will be waived from unblinding and 
expedited safety reporting if it represents one of the pre-specified disease-related efficacy 
endpoints (see also Section 9.6.1.4).
7.5.3
Emergency unblinding by the investigator
In the event of an emergency or any finding that requires unblinding, the investigator may 
break the blind for an individual subject via the IxRS according to the unblinding procedure 
outlined in the Investigator’s Guide. This system allows the investigator, or other responsible 
person, to identify the study drug if there is an emergency, without jeopardizing the 
double-blind integrity of the remainder of the study.
The code can be broken by the investigator, or other responsible person, when knowledge of 
the subject’s treatment is required for the clinical management of the subject. If it becomes 
necessary to know the individual treatment during the study and thus to break the code for 
that subject, the date and reason for unblinding are to be recorded on the relevant eCRF page. 
The investigator is required to promptly document and explain to the sponsor any premature 
unblinding (e.g. unblinding due to a serious adverse event [SAE]) of the study drug), 
and study drug must be discontinued permanently.
7.6
Drug logistics and accountability
All study drugs will be stored at the investigational site in accordance with GCP and GMP 
requirements and the instructions given by the clinical supplies department of the sponsor (or 
its affiliate/CRO), and will be inaccessible to unauthorized personnel. Special storage 
conditions and a complete record of batch numbers and expiry dates can be found in the 
sponsor’s study file; the site-relevant elements of this information will be available in the 
investigator site file. On the day of receipt, the responsible site personnel will confirm receipt of 
study drug via IxRS. The personnel will use the study drug only within the framework of this 
clinical study and in accordance with this protocol. Receipt, distribution, return and destruction

(if any) of the study drug must be properly documented according to the sponsor’s agreed and 
specified procedures.
Written instructions on study drug destruction will be made available to affected parties as 
applicable.
7.7
Treatment compliance
To monitor compliance, the investigator will be required to complete a drug dispensing log 
for each subject. The date of dispensing the study drug to the subject will be documented.
Study drug will be dispensed at each scheduled visit starting from Visit 1 (Day 1), as applicable.
Subjects will be instructed to return all of the study drug packaging including unused study 
drug and empty packaging.  Accountability must be performed at each visit (if applicable). 
Any discrepancies between actual and expected amount of returned study medication must be 
discussed with the subject at the time of the visit, and any explanation must be documented in 
the source records.

General considerations for prior and concomitant therapy
Figure 8–1 depicts the conditions of prior therapy on ACEIs and ARBs during the time 
leading up to the Screening Visit.  

For at least 4 weeks prior to the Run-in Visit, all subjects must be treated with  
either an ACEI or ARB, or both

Starting with the Run-in Visit, subjects should be treated with only an ACEI or ARB

For at least 4 weeks prior to the Screening Visit, subjects should be treated with the 
maximum tolerated labeled dose (but not below the minimal labeled dose) of 
only an ACEI or an ARB (not both), preferably without any adjustments to dose or 
choice of agent or to any other antihypertensive or antiglycemic treatment.

During the maintenance phase, there should preferably be no adjustments to dose of ACEI or ARB or to any other 
antihypertensive or antiglycemic treatment
The maximum tolerated labeled dose for ACEIs or ARBs should be the highest dose within
the ranges shown in Table 8–1 or according to local labels, as applicable, which the subject 
can safely tolerate. This dose should not be below the minimum labeled dose in order to 
maximize therapeutic benefit of background SoC.

Variations to these recommended dose ranges may exist in local clinical guidelines or labels. 
If the maximum labeled dose cannot be reached, the reason(s) should be documented in the 
eCRF. Antihypertensive therapy for renal and CVD protection will be administered according 
to local guidelines (see also Section 8.1.2 on medical management).
Depending on blood pressure, serum creatinine or eGFR, subjects may need to have their study 
drug dose or the dose of another concomitant medication reduced or discontinued. The dosage 
of SoC therapies should not be reduced in order to solely facilitate maintenance of study drug.
Prior medication that was discontinued to comply with the eligibility criteria of the study 
should also be recorded in the eCRF.
All concomitant medication including therapy for T2DM and DKD until the PT Visit will be 
recorded in the eCRF.
The following therapies are NOT permitted:

Concomitant therapy with eplerenone, spironolactone, any renin inhibitor, or 
potassium-sparing diuretic which cannot be discontinued at least 4 weeks prior to the 
Screening Visit and during study drug treatment

Concomitant therapy with both an ACEI and an ARB during the Run-in and Screening
periods, and during study drug treatment

Concomitant therapy with potent cytochrome P450 isoenzyme 3A4 (CYP3A4) 
inhibitors or inducers must be stopped at least 7 days before randomization and
is not allowed to be started during study drug treatment
A list of the most common medication regarded as potent CYP3A4 inhibitors or inducers is 
provided in Section 16.1.
Caution: Increases in finerenone exposure in combination with the following moderate 
CYP3A4 inhibitors cannot be excluded: amiodarone, aprepitant, bicalutamide, 
chloramphenicol, imatinib, mifepristone, norfloxacine, tacrolimus, verapamil, 
lapatinib, dasatinib, and nilotinib. Caution should also be exercised with 
concomitant use of high-dose acetylsalicylic acid (>500 mg/day), non-steroidal 
anti-inflammatory agents or trimethoprim or trimethoprim / sulfamethoxazole.
8.1.2
Medical management
ACEs and ARBs are considered as SoC therapy in patients with DKD and often prescribed to 
patients with DKD at early stages (8).
It is advisable to follow the recommendations of local guidelines for the management of 
CVD and CKD, the use of statins, anti-platelets and beta-blockers, and for glycemic control.

8.1.3
Control of blood pressure - amended
This section was changed in Amendment 3, see Section 15.1.2.10.
According to international guidelines, the recommended target blood pressure for subjects 
with T2DM and albuminuria, who are at increased risk of CVD and CKD progression, is 
<130/80 mmHg (39-41). However, this value may vary for the individual subject depending 
on concomitant diseases and well-being.
If blood pressure is considered uncontrolled by the investigator during the study period, 
non-potassium-sparing diuretics may be added as first choice to the treatment regimen if this 
was not already done. Thereafter, the addition of antihypertensive medication can be 
performed according to local guideline recommendations.
All concomitant medication added to the treatment regimen during the course of the study 
must be recorded in the eCRF.
8.1.4
Use of potassium supplements and lowering agents
If needed, potassium supplementation can be prescribed during the course of the study. 
Investigators are advised to monitor potassium carefully at each visit and to adapt the dose of 
any potassium supplementation in accordance with the potassium value measured at each visit 
or discontinue potassium supplementation once the potassium is within the normal range.
Potassium-lowering agents (e.g. sodium polystyrene sulfonate, calcium polystyrene sulfonate) 
are allowed to be started during treatment with study drug.
Any use of potassium supplementation and potassium-lowering agents must be documented 
in the eCRF.
8.2
Post-study therapy
The investigator will decide in consultation with the individual subject if additional treatment 
is required and choose from existing treatment options.
The investigator must provide follow-up medical care for all subjects who complete the study 
or who are prematurely withdrawn from the study, or must refer them for appropriate ongoing 
care as required.

Procedures and variables
9.1
Tabular schedule of evaluations - amended
This section was changed in Amendment 3, see Section 15.1.2.11 and Section 15.1.2.12.
Table 9–1 depicts the schedule of activities and evaluations for this study (16244).
An overview of the procedures for sub-studies of 16244 is provided in Table 9–2.
All randomized subjects will remain in the study until its termination, either:
(1) after positive adjudication of the targeted number of primary efficacy endpoint events, 
or
(2) at a recommendation of the DMC.
Thus, all subjects, including those who stopped taking study drug, should be asked to attend 
all the protocol-specified study visits in order to perform all assessments as stipulated in the 
visit schedule (Table 9–1).
If any subject refuses to return for the defined assessments or is unable to do so, every effort 
should be made to contact him/her or a knowledgeable informant by telephone to ask if any of 
the primary, secondary, or other endpoints have been reached at the scheduled visits for the
remaining duration of the study (see Section 6.4.1.1 for details).  Attempts to contact the 
subject should be documented in the subject’s records. If any subject refuses to be contacted 
by telephone (e.g. the subject withdrew consent to release further information), every effort 
should be made to obtain vital status (alive or dead) information through consultation of 
public databases, wherever allowed by local regulations.

Efficacy- amended
This section was changed in Amendment 3, see Section 15.1.2.25.
The parameters in Section 9.4.1 (primary), Section 9.4.2 (secondary) and Section 9.4.3
(exploratory) will be used to assess the efficacy of the study drug.
Efficacy endpoints will be evaluated by a Clinical Event Committee (CEC) (see Section 13.1.2).
Kidney failure is defined as either the occurrence of ESRD or an eGFR of less than 15 
mL/min/1.73 m², confirmed by a second measurement at the earliest 4 weeks after the initial 
measurement. ESRD is defined as the initiation of chronic dialysis (haemo- or peritoneal-
dialysis) for at least 90 days or renal transplantation. In addition, the eGFR threshold of 15 
mL/min/1.73 m² is consistent with the definition of kidney failure from KDIGO (Kidney 
Disease: Improving Global Outcomes)(3) and was chosen in order to include an objective 
component to the endpoint because the decision to initiate dialysis therapy or kidney 
transplantation may be affected by factors other than the eGFR. All other definitions of 
individual endpoints (e.g. CV death) will be provided in the Endpoint Manual.
9.4.1
Primary efficacy variable
The primary efficacy variable will be the time to the first occurrence of the composite endpoint
of onset of kidney failure, a sustained decrease of eGFR ≥ 40% from baseline over at least 
4 weeks, or renal death.
9.4.2
Secondary efficacy variables
Secondary efficacy variables will be as follows:

Time to first occurrence of the following composite endpoint:  cardiovascular (CV) 
death or non-fatal CV events (i.e. non-fatal myocardial infarction, non-fatal stroke, or 
hospitalization for HF)

Time to all-cause mortality

Time to all-cause hospitalization

For the investigation of systemic exposure to finerenone and its relationship with treatment 
effects, the plasma concentrations of finerenone will be determined at different time points 
using a sparse sampling approach in all participating subjects.  Details about the collection, 
processing, storage and shipment of samples will be provided separately (Laboratory Manual).
The plasma concentration versus time data of Visit 3 (Month 4) and at subsequent yearly 
visits will be evaluated descriptively, separated by dose. Plots will be prepared of all 
individual plasma concentrations vs. actual relative study times (time of sample collection 
after time of study drug administration). 
The PK data will be evaluated using non-linear mixed effect modeling (NONMEM). In 
addition, attempts will be made to identify whether the PK of finerenone is influenced by 
covariates and to explore exposure-response relationships. This evaluation will be described 
in a separate analysis plan and will be reported separately.
At Visit 3 (Month 4), a trough sample for the determination of finerenone plasma 
concentrations will be drawn before intake of study drug (if the sample could not be obtained 
at Visit 3, it can be drawn at Visit 4). At this visit, study drug will be administered at the study 
center by study personnel and the exact time of study drug intake on the day before the visit 
and on the day of the visit and the exact sampling time will be recorded in the eCRF. Ideally, 
the study personnel should contact the subject prior to Visit 3 to remind them not to take the 
study drug as usual in the morning at home.
At each of the yearly visits, one blood sample for the determination of finerenone plasma 
concentrations will be drawn during the visit after intake of study drug at home. The subjects 
should be advised to take their drug as usual in the morning at home and recall the time of 
drug intake. The exact time of study drug intake and the exact sampling times will be 
recorded in the eCRF.
PK sampling is not necessary if the study treatment was temporarily interrupted or 
permanently discontinued at the time of the visit.
The PK bioanalysis will be performed under the responsibility of Bayer Bioanalytics 
Laboratory, Bayer AG, 
, 42096 Wuppertal, Germany. Study 
responsible bioanalytical personnel will remain unblinded during the study.

Adverse events
9.6.1.1
Definitions - amended
This section was changed in Amendment 3, see Section 15.1.2.28.
Definition of adverse event (AE)
An AE is any untoward medical occurrence (i.e. any unfavorable and unintended sign 
[including abnormal laboratory findings], symptom or disease) in a patient or clinical 
investigation subject. Therefore, an AE may or may not be temporally or causally 
associated with the use of a medicinal (investigational) product.
All diagnoses, symptom(s), sign(s) or finding(s) with a start date from randomization 
onwards must be recorded as (S)AEs, except those related to study procedure. The latter have 
to be recorded as (S)AEs after informed consent has been obtained (see also end of this 
section for definition of SAE).
A surgical procedure that was planned prior to randomization by any physician treating the 
subject should not be recorded as an AE (however, the condition for which the surgery is 
required may be an AE).
In the following differentiation between medical history and AEs, the term 
‘condition’ may include abnormal physical examination findings, symptoms, diseases, 
laboratory or ECG findings:

Conditions that were present before randomization and for which 
no symptoms or treatment are present until randomization are recorded as medical 
history (e.g. seasonal allergy without acute complaints)

Conditions that started before randomization and for which symptoms or treatment are 
present after randomization, at unchanged intensity, are recorded as medical history 
(e.g. allergic pollinosis)

Conditions that started or deteriorated after randomization will be documented as 
(S)AEs

Conditions assessed as related to study procedure (such as invasive procedures 
and adjustment of SoC therapy [see Section 8.1.1 for guidance]) that 
start or deteriorate after signed informed consent must be documented as (S)AEs.

Definition of serious adverse event (SAE)
An SAE is classified as any untoward medical occurrence that, at any dose, meets any of the 
following criteria (a – f):
a.
Results in death
b.
Is life-threatening
The term ‘life-threatening’ in the definition refers to an event in which the subject was 
at risk of death at the time of the event, it does not refer to an event which 
hypothetically might have caused death if it were more severe.
c.
Requires inpatient hospitalization or prolongation of existing hospitalization
A hospitalization or prolongation of hospitalization will not be regarded as an SAE if 
at least one of the following exceptions is met:

The admission results in a hospital stay of less than 12 hours

The admission is pre-planned
(e.g. elective or scheduled surgery arranged prior to the first dose of study drug; 
admission is part of the study procedures as described in Section 9.2)

The admission is not associated with an AE
(e.g. social hospitalization for purposes of respite care).
However, it should be noted that invasive treatment during any hospitalization may 
fulfill the criterion of ‘medically important’ and as such may be reportable as an SAE 
dependent on clinical judgment. In addition, where local regulatory authorities 
specifically require a more stringent definition, the local regulation takes precedence.
d.
Results in persistent or significant disability / incapacity
Disability means a substantial disruption of a person’s ability to conduct normal life’s 
functions.
e.
Is a congenital anomaly / birth defect
f.
Is another serious or important medical event as judged by the investigator.
9.6.1.2
Classifications for adverse event assessment
All AEs will be assessed and documented by the investigator according to the categories 
detailed below.
9.6.1.2.1
Seriousness
For each AE, the seriousness must be determined according to the criteria given in 
Section 9.6.1.2.

9.6.1.2.2
Intensity
The intensity of an AE is classified according to the following categories:
Mild: usually transient in nature and generally not interfering with normal activities
Moderate: sufficiently discomforting to interfere with normal activities
Severe: prevents normal activities.
9.6.1.2.3
Causal relationship 
The assessment of the causal relationship between an AE and the administration of treatment 
is a decision to be made by the investigator, who is a qualified physician, based on all 
information available at the time of the completion of the eCRF.
The assessment is based on the question whether there was a ‘reasonable causal relationship’ 
to the study treatment in question.
Possible answers are ‘yes’ or ‘no’.
An assessment of ‘no’ would include:
1.
The existence of a highly likely alternative explanation, e.g. mechanical bleeding at 
surgical site.
or
2.
Non-plausibility, e.g. the subject is struck by an automobile when there is no 
indication that the drug caused disorientation that may have caused the event; cancer 
developing a few days after the first drug administration.
An assessment of ‘yes’ indicates that that the AE is reasonably associated with the use of the 
study treatment.
Important factors to be considered in assessing the relationship of the AE to study treatment 
include the following:
–
The temporal sequence from drug administration:
The event should occur after the drug is given. The length of time from drug exposure 
to event should be evaluated in the clinical context of the event.
–
Recovery on drug discontinuation (de-challenge), recurrence on drug re-introduction 
(re-challenge):
Subject’s response after de-challenge or re-challenge should be considered in view of 
the usual clinical course of the event in question.
–
Underlying, concomitant, intercurrent diseases:
Each event should be evaluated in the context of the natural history and course of the 
disease being treated and any other disease the subject may have.
–
Concomitant medication or treatment:
The other drugs the subject is taking or the treatment the subject receives should be 
examined to determine whether any of them might have caused the event in question.

–
The pharmacology and pharmacokinetics of the study treatment:
The pharmacokinetic properties (absorption, distribution, metabolism and excretion) 
of the study treatment, coupled with the individual subject’s pharmacodynamics 
should be considered.
–
The assessment is not possible.
Causal relationship to protocol-required procedure(s)
The assessment of a possible causal relationship between the AE and protocol-required 
procedure(s) is based on the question whether there was a ‘reasonable causal relationship’ to 
protocol-required procedure(s). 
Possible answers are ‘yes’ or ‘no’.
9.6.1.2.4
Action taken with study treatment 
Any action on study treatment to resolve the AE is to be documented using the categories 
listed below as follows:
Drug withdrawn
Drug interrupted
Dose reduced
Dose not changed
Dose increased
Not applicable
Unknown.
9.6.1.2.5
Other specific treatment(s) of adverse events
Specific treatment of AE(s), if given, is to be documented follows:
None
Remedial drug therapy
Other.

9.6.1.3
Assessments and documentation of adverse events (AEs) - amended
This section was changed in Amendment 3, see Section 15.1.2.29.
Attention is to be paid to the time of occurrence of AEs at all stages of the examination. Thus, 
the subject should be closely observed by the investigator.
AEs observed, mentioned upon open questioning by a member of the investigator’s team or 
spontaneously reported by the patient will be documented. The observation period for AEs will 
start with randomization and will end with the last visit of follow-up except for AEs related to 
study procedures; the observation period for the latter AEs will start with signed informed 
consent and will end with the last visit of follow-up. In the event of ongoing study-related 
AEs and medically relevant AEs at the end of the study, the investigator is urged to monitor 
the subject and document the outcome on the subject’s source document. After the end of the 
follow-up phase, there is no requirement to actively collect AEs including deaths. The type of 
information that should be assessed and recorded by the investigator for each AE is listed in 
Section 9.6.1.2.
See also Section 9.6.1.1 above for the differentiation between medical history and AEs.
The investigator is responsible for the grading of each category mentioned. An assessment of 
the seriousness of the event will be made by the investigator.  SAEs will be recorded on the 
AE page of the eCRF.
Emerging AEs will be allocated to the period in which they have started, e.g. a symptom 
starting in the treatment period and continuing in the follow-up period without deterioration 
will only be documented for that treatment period.
When assigning its cause, ‘death’ should not be recorded as an AE on the AE page.  
Instead, ‘death’ is the outcome of underlying AE(s).
For all serious adverse events (SAEs), the sponsor has to carry out a separate assessment for 
expectedness, seriousness and causal relationship to study drug.

The efficacy and pre-defined disease-related outcome events specified in Figure 9–1 will 
not be documented as (S)AEs.  Instead, these events will be documented only on the 
Outcome Event pages of the eCRF. In addition, they will not be reported as SAEs and will 
neither be unblinded, nor reported to regulatory authorities, IECs, or investigators (see also 
Section 9.6.1.4 for details). 
However, they will be collected in the eCRF, monitored by the DMC during the study and 
analyzed in the clinical report after study termination. If unexpected safety issues are 
identified, specific amendments will be implemented.

resolution or stabilization by submission of updated reports to the designated recipient.
The pre-defined disease-related efficacy events (see Table 13–1) will not be subject to AE 
documentation and expedited reporting as SAE because they are not unexpected in this study 
population. Thus, they will not be recorded as SAEs on the AE page and will not be sent to

Sponsor’s Pharmacovigilance department.  Instead, these events will be recorded on the eCRF 
as outcome events. Consequently, they will neither be unblinded, nor reported to regulatory 
authorities, IECs or investigators. However, they will be collected in the eCRF, evaluated by 
the CEC, monitored by the independent DMC during the study and analyzed in the clinical 
study report after termination of the study. The independent DMC will periodically review 
and assess all safety data for imbalances in safety outcomes. It is believed that in this way, 
patient safety can continue to be monitored throughout the duration of the trial, without 
affecting the integrity of the study.  Should unexpected safety issues be identified, specific 
amendments will be implemented.
All other SAEs that fulfill the seriousness criteria provided in Section 9.6.1.1 must be 
collected on the AE page of the eCRF and reported as SAEs to the Sponsor’s 
Pharmacovigilance department. All SAEs that fulfill SUSAR criteria as defined by the 
ICH E2A Guideline will be reported to the concerned authorities by expedited means (see 
details below).
The investigator is responsible for continuing to follow-up on all SAE reports (whether or not 
the event is related to study drug) until resolution of the event, or until the event is considered 
chronic and/or stable by the investigator and/or other physician who is responsible for the 
subject’s medical care. Follow-up SAE reports will be reported according to the same 
timelines as initial reports, as soon as new significant information becomes available.
Investigator’s notification of the sponsor
All investigators will be thoroughly instructed and trained on all relevant aspects of the 
investigator’s reporting obligations for SAEs. This information, including all relevant contact 
details, will be summarized in the investigator site file and updated as needed.
The investigator must report immediately (within 24 hours of the investigator’s awareness) 
all SAEs that are not exempted from SAE reporting occurring during the observation period 
defined in Section 9.6.1.3 to the recipient detailed in the instructions for SAE reporting 
included in the Investigator File.
Each SAE must be followed up until resolution or stabilization by submission of updated 
reports to the designated recipient.
SAEs occurring after the protocol-defined observation period will be processed by the 
sponsor according to all applicable regulations.
The efficacy and pre-defined disease-related outcome events as described in Section 9.6.1.3.1
will not be subject to AE documentation. Thus they will neither be unblinded, nor reported to 
regulatory authorities, IECs, or investigators in the event of fulfilling criteria for a SUSAR.
Notification of the IECs / IRBs
Notification of the IECs / IRBs about all relevant events (e.g. SAEs, suspected, unexpected, 
serious adverse reactions [SUSARs]) will be performed by the sponsor and/or by the 
investigator according to all applicable regulations.

In compliance with applicable regulations, in the event of a SUSAR, the subject’s treatment 
code will usually be unblinded before reporting to the competent authorities, IECs/IRBs. For 
reporting to investigators the treatment blind will be kept.
Notification of the authorities
The processing and reporting of all relevant events (e.g. SAEs, SUSARs) to the authorities 
will be done by the sponsor according to all applicable regulations.
Sponsor’s notification of the investigational site
The sponsor will inform all investigational sites about reported relevant events (e.g. SUSARs) 
according to all applicable regulations.
9.6.1.5
Expected adverse events
For this study, the applicable reference document is the most current version of the IB for 
finerenone.
Overview listings of frequent events that have occurred so far in the clinical development are 
shown in the current IB. If relevant new safety information is identified, the information will 
be integrated into an update of the IB and distributed to all participating sites.
The expectedness of AEs will be determined by the sponsor according to the applicable 
reference document and according to all local regulations.
9.6.2
Pregnancies
Female subjects of childbearing potential must have a negative serum or urine pregnancy test 
at screening and at yearly-intervals during study participation. If required by 
national/institutional regulations, a serological or urine pregnancy test in subjects of 
childbearing potential should be performed more often (e.g. at every visit). 
The investigator must report to the sponsor any pregnancy occurring in a female study subject 
during her participation in this study. The outcome of the pregnancy should be followed up 
carefully, and any outcome of the mother and the child at delivery should be reported.
The child’s health should be followed up until birth.
For a pregnancy in the partner of a male study subject, all efforts should be made to obtain 
similar information on course and outcome of the pregnancy and the health of the child, 
subject to the partner’s consent.
For all reports, the forms provided are to be used. The investigator should submit them within 
the same timelines as an SAE, i.e. within 24 hours of his/her awareness.

Other procedures and variables
9.7.1
Monitoring of potassium - amended
This section was changed in Amendment 3, see Section 15.1.2.31.
Hyperkalemia is a frequent event in subjects with DKD progressing to ESRD and one of the 
main risks identified from previous studies with MRAs including finerenone. Potassium will 
be monitored closely during this study, with assessments of potassium concentration 
scheduled at all visits (see Table 9–1 for schedule).
During treatment with study drug, all assessments of potassium, including re-tests, will be 
performed at both local and central laboratories.  Due to sample handling and extended 
transportation time to the central laboratory, falsely elevated serum potassium values in 
centrally (but not locally) analyzed samples have been observed in previous studies with 
finerenone.  Since the value of potassium in the local sample is usually not affected by this 
and results from the local laboratory are available earlier, local samples will be taken not only 
for safety purposes but also for dose adjustments.
Re-checking of potassium values must be done at the latest within 72 hours of the investigator 
being aware of results that need confirmation.  The investigator can perform a re-test at any 
time if they consider it necessary to confirm the potassium concentration of the local or the 
central sample.
Adjustment of dose after start of study drug intake based on blood potassium levels is 
provided in Table 9–3.

Continue on the same dose.
>5.5
Withhold study drug and re-check potassium within 72 hours.
Second and subsequent samples:
≤5.0
Re-start study drug at lower dose.
>5.0
Continue to withhold study drug; continue to monitor potassium and restart 
study drug at the lower dose only if potassium is ≤5.0
NOTE: lower dose = 10 mg once daily; higher dose = 20 mg once daily.

The following aspects have also to be taken into consideration:

Blood potassium should be measured 4 weeks (± 7 days) after re-starting treatment or 
dose adjustment, especially after up-titration

If central laboratory results for blood potassium differ from local laboratory results to 
such an extent that the investigator is uncomfortable with the dose adjustment guidance 
shown in Table 9–3 , blood sampling may be repeated at the investigator’s discretion

If the subject is already on the lower dose of study drug but hyperkalemia recurs soon 
after a previous event of hyperkalemia with interruption of study drug, and there is 
no explanation for the recurring hyperkalemia event other than intake of study drug, 
permanent discontinuation of study drug is recommended

If blood potassium is > 6.5 mmol/L, an ECG should be obtained

Subjects will maintain their normal diet throughout the study and will not be given any 
specific advice on dietary potassium restrictions.

considered for statistical analysis, unless otherwise specified. Details of the collections, 
shipment of samples and reporting of results by the central laboratory will be provided to the 
investigators in the Laboratory Manual.
Laboratory evaluations (hematology, HbA1c, clinical chemistry and urinalysis parameters) 
are shown in Table 9–4. Hematology, HbA1c and (full) clinical chemistry are considered as 
‘Full central laboratory’ assessments.
Laboratory evaluations will be performed according to the visit schedule (see Table 9–1).

Local laboratory - amended
This section was changed in Amendment 3, see Section 15.1.2.32.
In addition to samples for the central laboratory, other blood safety samples will be taken 
from Visit 1 (Day 1; baseline) onwards (see Table 9–1) for analysis at the local laboratory. 
These samples may be obtained up to 72 hours before a scheduled visit.
The following clinical chemistry parameters must be measured for as long as subject is not 
prematurely discontinued from the study drug:

Blood potassium

Blood creatinine (eGFR will be calculated automatically in the eCRF using the 
CKD-EPI formula (36)).
Up-titration of the study drug will be based on local potassium and eGFR values and must be 
documented in the eCRF. Down-titration of the study drug will occur for safety reasons only 
(for guidance, see Section 9.7.1 and Table 7–2).
Potassium values should be recorded using a single decimal point (e.g. 4.5 mmol/L or mEq/L).
In the event of hyperkalemia, please see Section 9.7.1 for guidance on treatment.
In women of childbearing potential, a pregnancy test will be performed locally, at the 
Screening Visit and following randomization at yearly visits as long as the subject is not 
permanently discontinued from the study drug (since more than 7 days). However, pregnancy 
tests in subjects of childbearing potential should be performed more frequently (e.g. at every 
visit) if this is required by national / institutional regulations. Both serological and urine tests are 
acceptable.

Physical examination
Abnormal physical examination findings are recorded either as medical history or as an AE 
(see Section 9.6.1.1).
A complete physical examination will be performed at the Run-In and Screening Visits, at the 
yearly visits and again at the PD and EOS Visits (see Table 9–1).  
9.7.4
Weight and height
Body weight (to the nearest 0.1 kg in indoor clothing without shoes) will be measured at 
all scheduled visits except the PT Visit (see Table 9–1). Height as well as hip and waist 
circumference in centimeters will be only measured at the Run-in Visit.
9.7.5
Measurement of vital signs
Vital signs will be assessed at all scheduled visits except the PT Visit (see Table 9–1). This 
will include blood pressure (BP) and pulse measurements.
BP will be measured by using a standard sphygmomanometer with an appropriate size cuff in 
the sitting position after 5 minutes of rest.
There must be 3 consecutive BP readings with at least a 1-minute interval between each reading
(all 3 readings should be obtained within a maximum of 20 minutes).
The same arm and the appropriate size cuff should be used for measurements at each visit. 
9.7.6
Electrocardiogram (ECG) - amended
This section was changed in Amendment 3, see Section 15.1.2.33.
A standard 12-lead ECG will be performed locally at the Run-In Visit, Screening Visit, at 
Visit 1 (Day 1; baseline), at the yearly visits, and again at the PD and EOS Visits (see Table 
9–1). If there is any clinical indication, unscheduled 12-lead ECGs can be performed at any 
point during the study.
In addition, an ECG should be obtained if potassium >6.5 mmol/L.
The interpretation of the tracing must be made locally by a qualified physician.
The date of the recording must be documented on the ECG section of the eCRF. Each ECG 
tracing should be labeled with the study number, subject number, and date and kept in the 
source documents at the study site.
Clinically significant abnormalities should be reported as AEs or outcome event as appropriate
(e.g. new onset atrial fibrillation) when not already reported in the medical history or in one of 
the previous recordings and in case of worsening of previous findings.

questionnaires is provided in Section 16.3.
The subject will be instructed to fill in the questionnaires himself / herself before any other 
procedure of each visit. Subsequently, a member of the site investigator’s team will enter the 
responses into the eCRF.

Sub-studies
The results of the sub-studies for Study 16244 will not be presented in its main clinical study 
report (CSR) but will be provided as separate reports.
9.7.8.1.1
Echocardiography sub-study - amended
This section was changed in Amendment 3, see Section 15.1.2.34.
At selected centers, approximately 500 subjects per study consenting to participate in 
Studies 16244 and 17530 will be invited to take part in an echocardiography sub-study. 
Subjects will be asked to sign a separate informed consent to participate in this sub-study. 
Diabetes mellitus, hypertension and dyslipidemia are CV risk factors which contribute to the 
CVD continuum and potentially results in a sequence of CV events. The development of HF in 
subjects with DKD is the most common CV complication and imposes significant morbidity 
and mortality (42, 43). Patients with symptomatic HFrEF are excluded from the Phase III 
program of finerenone in DKD. However, before becoming symptomatic, sub-clinical cardiac 
dysfunction and abnormal leftventricular structure including leftventricular hypertrophy can 
be demonstrated in the majority of subjects with moderate CKD. Imaging plays a central role 
in the diagnosis of structural heart disease. Of the various imaging modalities available, for 
reasons of accuracy, availability, safety and cost, echocardiography is the method of choice in 
subjects with suspected or the beginnings of structural heart disease.
In all participating sites, echocardiography will be performed according to a study-specific 
protocol at Visit 1 (Day 1; baseline), at yearly visits and at the end of the study (either at the 
PD Visit or the EOS Visit). If a baseline assessment is not available or analysable, the subject 
will not continue in to undergo echocardiography assessments due to inability to perform a 
comparison against baseline.
Echocardiography examinations, data collection and procedures for central blinded adjudication 
in the echo core laboratory are given in the Echocardiography Manual. In addition, each time an 
echocardiography is performed, one blood sample should be drawn to assess the following 
biomarkers shown in Table 9–5.

Biomarker
Mechanism
Rationale for assessing this biomarker
NT-proBNP
myocardial 
pressure-volume 
overload
NT-proBNP is typically increased in patients with asymptomatic or 
symptomatic left ventricular dysfunction and is associated with coronary 
artery disease and myocardial ischemia.
Galectin-3
(Cardiac) fibroblast / 
cardiomyocyte stress
Gal-3 is barely detectable in cardiomyocytes but cardiac fibroblasts 
express high levels of this protein Serum Gal-3 predicts short-, mid- and 
long-term mortality and HF-associated hospitalization in early and late 
stage HFpEF and HFrEF
sST2
Myocardial stress
In HF, ST2 mRNA and protein are upregulated and protein becomes 
detectable in serum. In severe chronic HF, change in serum sST2 
independently predicts mortality or transplant.
PIIINP 
Tissue remodeling / 
collagen synthesis
PIIINP is produced and secreted into the circulation upon collagen 
synthesis Increased baseline PIIINP levels are associated with increased 
risk of death in CHF patients and decreased in response to 
spironolactone or eplerenone
OPN
Inflammation / tissue 
remodelling
OPN mRNA and protein are hardly detectable in healthy myocardium, but 
becomes detectable upon cardiomyocyte and fibroblast injury. 
Abbreviations: CHF = chronic heart failure;  CRT = cardiac resynchronization therapy;  HFp/rEF = heart failure 
with preserved/reduced ejection fraction; NT-proBNP = N-terminal pro-peptide of brain 
natriuretic peptide; OPN = osteopontin;  PIIINP = N-terminal pro-peptide of collagen III
Local echocardiography examinations will be performed to capture at least all of the variables 
listed in Table 9–6. The recordings of echocardiography examinations will be digitally 
transferred to the vendor / echo core laboratory (ECL) for centralized interpretation and 
reporting. Echocardiography from videotape will be digitized, and analyses will be performed 
on an offline analysis workstation. Quantitative measures on all study echocardiographies will 
be performed by dedicated analysts at the core laboratory, who will be blinded to clinical 
information and randomized treatment assignment. The echocardiography results will not be 
provided to sites.

Biomarker sub-study 
At selected centers, the first approximately 500 subjects per study who consent to participate 
in Studies 16244 and 17530 will be invited to take part in a biomarker sub-study. Subject will 
be asked to sign a separate informed consent to participate in this sub-study.
For participating sites, samples for biomarkers will be drawn at Visit 1 (Day 1; baseline), at 
Visit 3 (Month 4), at yearly visits and at the end of the study (either at the PD Visit or the 
EOS Visit). The selected biomarkers studied are the ones believed to be relevant to the 
pathophysiology of the disease processes of CV and renal disease progression. The 
biomarkers studied are shown in Table 9–7.

Iohexol clearance sub-study - amended
This section was changed in Amendment 3, see Section 15.1.2.35.
At selected centers in Italy, at least 50 subjects per study consenting to participate in 
Studies 16244 and 17530 will be invited to take part in an iohexol clearance sub-study. 
Subjects will be asked to sign a separate informed consent to participate in this sub-study. 
Subjects who are included in this sub-study will have their GFR directly measured by the 
iohexol plasma clearance technique (44).
Iohexol plasma clearance will be assessed at Visit 1 (Day 1, baseline), at Visit 3 (Month 4) 
and thereafter at every other visit (i.e. every 8 months) until the end of the study (either at the 
PD Visit or the EOS Visit) plus an additional assessment at the PT Visit (recovery). The 
Iohexol results will not be provided to the sites.

The variables for evaluation in this sub-study are as follows:

Primary variable:
Chronic GFR slope, i.e. the rate of GFR decline from Visit 3 (Month 4) after 
randomization to the end of the treatment period.
As previously addressed in the AASK trial, this approach is needed to address the 
biphasic change in GFR decline that is expected after exposure to the study drug. 
The GFR slope will be determined separately during the first 4 months following 
randomization (acute slope) and after 4 months (chronic slope). The acute and chronic 
phases are differentiated because the study treatment might have acute effects on 
GFR that may differ from its long term effects on disease progression (45, 46)
(an approach approved by the U.S. National Institute of Diabetes and Digestive and 
Kidney Diseases (47)).

Exploratory variable:
o
Change in GFR from Visit 1 (baseline) and at the PT Visit (recovery)
o
Acute GFR changes from baseline to Visit 3 (Month 4)
o
Acute GFR changes from the end of the treatment period until the end of the 
recovery period
o
Correlation analyses between short term GFR changes between Visit 1 (baseline) 
and Visit 3 (Month 4) after randomization, and long term GFR decline (chronic 
slope).
An ANCOVA model will be fitted to the GFR efficacy variables including the factors 
treatment group, the stratification factors (type of albuminuria, eGFR category) and the 
baseline GFR as covariate.  Corresponding two-sided 95% confidence intervals will be 
computed. In addition, correlation analyses between short term GFR changes between 
Visit 1 (baseline) and Visit 3 (Month 4) after randomization, and long term GFR decline 
(chronic slope).

Statistical methods and determination of sample size
10.1
General considerations
Statistical analysis will be performed using SAS; the version used will be specified in the 
statistical analysis plan (SAP).
A log-normal distribution is assumed for serum creatinine and UACR. For all other metric 
variables, a normal distribution is assumed. The distributional assumptions will be 
investigated and if necessary, nonparametric methods or transformation of the data will be 
considered. 
All variables will be analyzed by descriptive statistical methods. The number of data 
available, mean, standard deviation (SDv), minimum, median, and maximum will be 
calculated for metric data. The geometric mean and SDv will be provided instead of the 
arithmetic mean and SDv for the variables where lognormal distributions are assumed. 
Frequency tables will be generated for categorical data.
Baseline values will be defined as the last non-missing measurement before randomization
(Visit 1). If the last observation available prior to randomization is the measurement from the 
Screening Visit, this would be used as the baseline value. This also includes assessments from 
a local laboratory, in case that prior to randomization, no assessment from the central 
laboratory is available. Otherwise baseline will be missing. The measurement from the Run-in 
Visit will not be used as a baseline value. If more than one measurement was planned for a 
scheduled time point, for example blood pressure measurements and heart rate, the mean 
value of the last set of measurements per time point prior to randomization will be used as the 
baseline value.
Only the data provided by the central laboratory will be used for analysis, values from local 
laboratories will not be used in the statistical analysis and listed only. 
In the event of repeated measurements for Pre-treatment Visits and the Visit 1 (Day 1; baseline),
the closest measurement prior to randomization will be used for analysis instead of the 
scheduled measurements. At all visits post-randomization and unless stated otherwise, only 
the values at scheduled measurements will be used for analysis.
The derived visit ‘Any time post baseline’ (applicable for efficacy) will include any measurement 
after randomization, including unscheduled assessments. For the derived visit ‘Any time on 
treatment’, only assessments up to 30 days after last study drug administration, including 
unscheduled assessments, will be considered (applicable for efficacy; for safety assessments 
within 3 days after last study drug administration will be considered).
Further details on the statistical analyses will be provided in the SAP that will be approved 
before database release.

10.2
Analysis sets - amended
This section was changed in Amendment 3, see Section 15.1.2.36.
Safety analysis set (SAF): 
All randomized subjects who have taken at least 1 dose 
of study drug 
Full analysis set (FAS): 
All randomized subjects 
Per-protocol analysis set (PPS): 
All subjects of the FAS without any validity findings
Pharmacokinetic analysis set (PKS): All finerenone-treated subjects with at least 1 valid 
finerenone plasma concentration and without protocol 
deviation, which would interfere with the evaluation of 
the PK data.
Listing only set (LOS):
All other subjects screened who did not receive any 
dose of study drug or for whom no data after beginning 
of treatment are available will be classified as LOS.  
Their data will be presented in the individual subject 
data listings but will not be included in any statistical 
analysis.
All subjects will be analyzed according to the planned treatment in FAS (the intent-to-treat or 
ITT principle). All subjects will be analyzed according to the actual treatment in SAF and 
PPS. If a subject receives both treatments due to a bottle error, the treatment actually received 
for the majority of the time in the study will be used in SAF and PPS.
The stratum variable type of albuminuria and eGFR category used in the statistical analysis 
will be derived based on the screening UACR and eGFR assessment, respectively. All 
subjects will be analyzed according to their correct stratification category. In the event of 
stratification errors, the primary analysis will also be repeated based on the stratification 
category used in the randomization as a sensitivity analysis.

subjects discontinuing the treatment and follow-up epochs, together with the primary reason 
for discontinuation will be presented by treatment group and overall in separate tables. In 
addition, the number of subjects with important deviations and validity findings will be 
presented overall, by investigator and country for each treatment group, and in total. The 
frequencies of each important deviation and validity finding will be presented by treatment 
group and in total.

Demography and other baseline characteristics - amended
This section was changed in Amendment 3, see Section 15.1.2.38.
Demography includes age, sex, race, ethnicity, region (North America, Europe, Asia, Latin 
America and others), body weight, body height, BMI, hip and waist circumference, smoking 
history (never, former, current smoker) and alcohol consumption. Other baseline 
characteristics include baseline UACR, serum potassium, categories for serum potassium 
(≤4.5 mmol and > 4.5 mmol), eGFR (calculated by CKD-EPI formula), serum creatinine, 
HbA1c, values for vital signs parameters (i.e. systolic blood pressure, diastolic blood pressure 
and heart rate).
All demographic data and baseline characteristics will be tabulated by treatment group and 
overall. The demographic and other baseline characteristics table will also be presented, 
separated by each level of the stratification factors type of albuminuria, region and eGFR 
category.
The non-stratified demographic and other baseline characteristics table will be repeated for all 
other analysis sets if they differ in sample size from the FAS.
Demographics and other baseline characteristics will be presented for the FAS separately for 
the subjects belonging to PPS or not (only overall, not by treatment group).
10.3.1.4
Medical history
Medical history will be coded using the MedDRA dictionary. Medical history will be 
presented for each MedDRA Primary System Organ Class and Preferred Term by treatment 
group and overall in a summary table. Additional medical history terms by Standardized 
MedDRA Queries (SMQ) will also be presented.
10.3.1.5
Concomitant medication
Concomitant medication will be coded using the WHO Drug Dictionary (WHO-DD). The 
number of subjects who took at least one concomitant medication, the number of subjects 
who took at least one medication that started and ended before administration of study drug 
and the number of subjects who took at least one concomitant medication that started after 
start of study drug will be presented by treatment group and overall using ATC classes and 
subclasses. These tables will be repeated, summarizing the number of subjects with 
medication in the Bayer drug groups of interest (including ACEI, ARBs, beta-blocker, 
diuretics, potassium supplements, potassium lowering agents, alpha blocking agents, calcium 
channel blockers, centrally acting antihypertensives and strong, moderate and weak CYP3A4 
inhibitors and CYP3A4 inducers). A subject will be counted only once within each ATC 
class / subclass or Bayer drug group, respectively.

Treatment duration, extent of exposure, up-titration status and 
compliance - amended
This section was changed in Amendment 3, see Section 15.1.2.39.
The analyses described in this section will be repeated for the SAF and PPS if they differ in 
sample size from the FAS.
Treatment duration (number of months with study drug intake) will be summarized using 
descriptive statistics by treatment group and overall. In addition, treatment duration will be 
categorized and presented with the corresponding number and percentage of subjects by 
treatment group and overall. Further specification of the categories will be provided in the 
SAP.
A table will be presented with the absolute and relative frequencies of subjects still in the 
study at each visit. Kaplan-Meier plots for ‘Time to end of study treatment’ will be provided. 
The extent of exposure to study drug (total amount of intake in grams) will be summarized 
using descriptive statistics by treatment group. 
The up-titration status (yes/no), regardless of actual or sham up-titration, will be summarized 
with absolute and relative frequencies per treatment group for each visit as well as subjects 
never up-titrated, up-titrated once, and up-titrated more than once. Compliance (as a percentage)
will be calculated as follows: 
100 * Number of taken tablets / Number of planned tablets.
The number of planned tablets will be calculated as follows:
(Days from randomization to last intake of study drug + 1) * Number of planned tablets per 
day.
All tablets, including the dummy placebo tablets, will be counted. For subjects who withdraw 
prematurely from the study drug, compliance will be calculated up to the time of last dose.
The compliance will be summarized descriptively by treatment group and overall. In addition, 
percent of compliance will be categorized into three groups, <80%, ≥80 to ≤120% and 
>120%, and the categories will be summarized by treatment group and overall.

Randomized subjects without an event of the primary composite endpoint at the time of 
analysis will be censored at the date of their last visit or date of non-renal death. Subjects 
without information about the primary composite endpoint after baseline will be censored at 
Day 1.
The weighted Bonferroni-Holm procedure will be used for the hierarchical testing of the 
primary and secondary efficacy endpoints. 

If the primary renal composite endpoint achieves statistical significance at a two-sided 
p-value ≤0.03333 (z0.9833 = 2.128), the secondary CV endpoint will be tested at the 
two-sided 0.05 level. 

Alternatively, if the secondary CV endpoint achieves statistical significance at a 
two-sided p-value ≤ 0.01667 (z0.99167 = 2.394), the primary renal composite endpoint 
will be tested at the two-sided 0.05 level.

Only if both the renal and CV endpoints achieve formal statistical significance, 
can further secondary endpoints be tested.
In order to evaluate whether finerenone is superior to placebo in prolonging the time to the 
first event of the primary composite endpoint, the following null hypothesis will be tested 
using the log-rank test at the significance level given above:
H0: Sfinerenone(t) = Splacebo (t) for all time points t ≥ 0
The alternative hypothesis will be:
H1: Sfinerenone (t) > Splacebo (t) for at least one time point t ≥ 0 and 
Sfinerenone (t) ≥Splacebo (t) for all time points t ≥ 0,
where Sfinerenone denotes the ‘survival’ function of the finerenone treatment group and 
Splacebo denotes the ‘survival’ function of the placebo treatment group. ‘Survival’ means 
‘no event of the primary composite endpoint’ in this context. 
The following decision rule to test the null hypothesis will be applied:
According to the size of this study it is justified to assume under H0 a sufficiently close 
approximation of the log-rank test (48) to the normal distribution. If the z-value from the 
log-rank test (for the difference Sfinerenone – Splacebo), stratified by the stratification factors 
(type of albuminuria, region, eGFR category) is larger than the critical quantile from the 
normal distribution (z0.975 = 1.960 or z0.9833 = 2.128), the null hypothesis will be rejected in 
favor of the alternative hypothesis.
The nominal significance levels and the critical values at the final analysis will be adjusted to 
account for the interim analysis, see Section 10.5 for more details.
In order to provide a point estimate of the hazard ratio and a corresponding 
two-sided 95% or 96.67% confidence interval, a stratified Cox proportional regression model 
will be used. Kaplan-Meier curves will be provided for the cumulative proportions of events 
by treatment groups.

10.3.3.2
Primary efficacy variable: supportive analyses
The primary analysis of the primary efficacy variable will be repeated in the PPS as a 
supportive analysis. Further supportive analyses of the primary efficacy variable will be 
performed in the FAS and PPS.
The absolute and relative frequency of subjects with an event of the primary composite 
endpoint until 6, 12, 18, 24, 30 and 36 months will be displayed overall and by treatment 
group. The number of individual events of the primary composite endpoint until 6, 12, 18, 24, 
30 and 36 months will be displayed overall and by treatment group. Frequencies will be 
calculated for the number of individual events of the primary composite endpoint per subject 
until 6, 12, 18, 24, 30 and 36 months overall and by treatment group.
Kaplan-Meier estimates (the 25th, 50th and 75th percentile) of the time to the first event of the 
primary composite endpoint (including 95% or 96.67% confidence interval), overall 
‘survival’ rates at 6, 12, 18, 24, 30 and 36 months and Kaplan-Meier curves will be presented 
for each treatment group. These analyses will be presented in total and for each level of the 
stratification factors (type of albuminuria, region, eGFR category). 
The censoring mechanism of subjects without an event of the primary composite endpoint at 
the time of analysis is assumed to be non-informative for the primary efficacy analysis. 
Sensitivity analyses will be performed, assessing the impact of potential informative 
censoring of such subjects. These will include the use of different imputation rules for 
considering subjects without an event of the primary composite endpoint as having an event 
or being censored, and will be further outlined in the SAP. 
For the individual events of the primary composite endpoint, the number of events per patient 
year will be presented overall and by treatment group. The frequency of events per patient 
year for a treatment group will be calculated as the number of events observed for a treatment 
group (counting all events, not only the first one) divided by the sum of the days from first 
intake of study drug for all subjects within a treatment group and multiplied by 365.25.
An ‘on-treatment’ analysis will be performed, including only events occurring while taking 
study drug or until 30 days after stop of study drug. This analysis will be performed in the 
FAS.
10.3.3.3
Secondary efficacy variables: primary analysis
The primary analysis of the secondary efficacy variables will be analyzed in FAS.
The testing procedure for the secondary CV composite endpoint is described in 
Section 10.3.3.1. If the null hypothesis of both the primary renal composite endpoint analysis 
and the secondary CV composite endpoint analysis are rejected using the Bonferroni-Holm 
procedure as described in Section 10.3.3.1, the further secondary efficacy variables will be 
tested hierarchically in the order as they are listed in Section 9.4.2, while keeping the 
two-sided significance level of 5.0%. Otherwise, the testing of the secondary efficacy 
variables will be performed in an explorative manner only. 
The primary analysis of the secondary time-to-event endpoints will be analyzed analogously 
to the primary analysis of the primary composite endpoint.

All other efficacy variables will be analyzed in FAS and PPS in an explorative manner. 
10.3.3.5.1 UACR and albuminuria - amended
This section was changed in Amendment 3, see Section 15.1.2.40.
UACR during the study will be summarized descriptively by treatment group and visit 
including ratios to baseline. These analyses will be performed overall and separated by the 
stratification factors (type of albuminuria, region and eGFR category). 
The log-transformed ratio of UACR to baseline at each visit up to Month 24 will be analyzed 
by a mixed model with the factors treatment group, visit, treatment by visit interaction, 
factors for the stratification levels (type of albuminuria, region and eGFR category), 
log-transformed baseline value as covariate nested within type of albuminuria and 
log-transformed baseline value by visit interaction. Pairwise ratios between the finerenone 
and the placebo treatment group will be calculated and corresponding two-sided 95% 
confidence intervals will be computed.
Frequency tables will be generated for the number of subjects with a relative decrease and 
increase in UACR of ≥30%, ≥40% and ≥50% from baseline UACR. The analysis will be 
performed for each visit and for any time post baseline. The analysis will also be performed 
stratified for each level of the stratification factors (type of albuminuria, region and eGFR 
category).
A shift table will be provided displaying the number of subjects who changed from baseline 
to each visit from very high albuminuria to high albuminuria, from very high albuminuria to 
UACR < 30mg/g, from high albuminuria to UACR < 30mg/g, from high albuminuria to very 
high albuminuria and from UACR < 30mg/g to high and very high albuminuria by treatment 
group and overall. The albuminuria category changes will only be considered as shifts, if they 
are accompanied by a UACR decrease of at least 30% from baseline to each visit.
The additional categorical UACR efficacy variables listed in Section 9.4.3 will be summarized 
for presence or absence of the event using logistic regression with the factors treatment group

and stratification levels (type of albuminuria, region and eGFR category). Pairwise differences 
between the finerenone and the placebo treatment group will be calculated and corresponding 
two-sided 95% confidence intervals will be computed.
10.3.3.5.2 Decrease in eGFR
eGFR will be summarized descriptively by treatment group and visit including absolute and 
relative changes to baseline. These analyses will be performed overall and separated by the 
stratification factors (type of albuminuria, region and eGFR category). 
The absolute change of eGFR to baseline at each visit until Month 24 will be analyzed by a 
mixed model with the factors treatment group, visit, treatment by visit interaction, factors for 
the stratification levels (type of albuminuria, region and eGFR category), baseline value as 
covariate nested within eGFR category and baseline by visit interaction. Pairwise differences 
between the finerenone and the placebo treatment group will be calculated and corresponding 
two-sided 95% confidence intervals will be computed.
Frequency tables will be generated for the number of subjects with a relative decrease in 
eGFR of ≥30%, ≥40%, ≥50% and ≥57% from baseline eGFR. The analysis will be performed 
for each visit and for any time post baseline. In addition, for each patient, the annual change 
in eGFR will be calculated by fitting the patient’s eGFR assessments into a linear regression 
model with time as the independent variable. The derived annual change will be analyzed 
using an ANCOVA model including baseline, treatment group and stratification factors as 
fixed-effects.
10.3.3.5.3 Health-related quality of life (HR-QoL)
Domain scores for each of the 5 domains (PCS, MCS, Burden of Kidney Disease, Symptoms / 
Problems, and Effects of Kidney Disease) will be calculated according to the KDQOL scoring 
instruction (http://www.rand.org/health/surveys_tools/kdqol.html [6th September 2013]). The 
KDQOL-36 domain scores will be presented by visit and treatment group by means of 
number of observations, number of missing values, minimum, first quartile, mean, SDv, 
median, third quartile, and maximum, including the changes from baseline. 
Summary scores will be calculated out of the 5 dimensions according to the scoring 
instructions from Europe and the US [refer to the EQ-5D-5L User Guide (49) and to the 
EQ-5D Value Sets (50)]. The values and the changes from baseline of the summary scores 
and the EQ Visual Analogue scale (VAS) will be summarized by treatment group and visit 
using the same descriptive statistics as for KDQOL. 
For details on HR-QoL questionnaires, see Section 16.3.
10.3.3.5.4 New diagnosis of atrial fibrillation, new diagnosis of heart failure and 
regression of albuminuria
These other exploratory efficacy variables will be summarized for presence or absence of the 
event using logistic regression with the factors treatment group and stratification levels (type 
of albuminuria, region and eGFR category). Pairwise differences between the finerenone and 
the placebo treatment group will be calculated and corresponding two-sided 95% confidence 
intervals will be computed.

10.3.3.6
Subgroup analyses
Exploratory subgroup analyses are planned for the primary efficacy variable, also the 
secondary efficacy variables.  This will include descriptive statistics and a statistical test for 
interaction.
The following subgroups will be considered for exploratory subgroup analyses:

Region (North America, Latin America, Europe, Asia, Others)

eGFR category at screening and baseline (eGFR 25 to < 45, 45 to < 60 and 
≥60 mL/min/1.73m2)

Type of albuminuria at screening and baseline (high albuminuria vs very high 
albuminuria) 

History of CVD (present, absent)

Baseline serum potassium (≤ 4.5 vs. > 4.5 mmol/L)

Systolic blood pressure at baseline (90 to <130 , 130 to <160 and ≥ 160 mmHg).
It is anticipated that in these proposed subgroups for analysis, differences in treatment effects 
may be observed according to the screening or baseline characteristics defined, due in part to 
the differences in the risk of clinical events expected in the different subgroups.
Furthermore, subgroup analysis usually required will be performed, including the following 
subgroups:

Race

Gender

Age group.
10.3.4
Safety variables
All analyses on safety and tolerability data will be performed in the SAF.
The following safety variables will be assessed during the study:

SAEs and AEs leading to discontinuation of treatment with study drug

Change in body weight

Change in serum potassium from baseline

Number of subjects with hyperkalemia (serum potassium > 5.5 mmol/L)

Number of subjects with severe hyperkalemia (serum potassium > 6.0 mmol/L)

Number of subjects with hospitalization for hyperkalemia

Number of subjects discontinuing study drug permanently due to hyperkalemia

Change in vital signs from baseline


Change in renal function measured by eGFR (CKD-EPI) change from baseline

Number of subjects with hospitalization for worsening of renal function

Number of subjects discontinuing study drug permanently due to worsening of 
renal function

Changes in laboratory values.
10.3.4.1
Adverse events
Adverse events (AEs) will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA, latest version available prior to data base freeze). A listing will be provided 
linking the original investigator terms and the coded terms. AEs will also be presented 
grouped by SMQs. 
AEs that started or worsened after the first dose of study drug up to 3 days after any 
temporary or permanent interruption of study drug will be considered as treatment emergent 
AEs (TEAEs).
An overall summary of all AEs and TEAEs will be generated by treatment group. 
The number of subjects with TEAEs, post-treatment AEs occurring more than 3 days after 
stop of study drug, treatment-emergent SAEs, treatment-emergent study drug-related AEs, 
treatment-emergent study drug-related SAEs, TEAEs causing permanent discontinuation of 
study drug, treatment-emergent non-serious AEs, non-serious AEs, TEAEs by maximum 
intensity, treatment-emergent SAEs by maximum intensity, drug-related TEAEs by maximum 
intensity, TEAEs by worst outcome and treatment-emergent SAEs by worst outcome will be 
summarized by treatment group using MedDRA terms grouped by Primary System Organ 
Class and Preferred Term. 
In case of events with different intensity within a subject, the maximum reported intensity 
will be used. If intensity is missing, the event will be considered as severe. If the same event 
is reported as both unrelated and related to the study drug within a subject, the event will be 
reported as related to study drug. If the drug relationship is missing, the event will be 
considered as being related to the study drug.
Separate tables summarizing TEAEs, treatment-emergent study drug-related AEs, and SAEs
that occurred in more than 5% of the subjects will be provided.
Deaths, SAEs and AEs leading to permanent study drug discontinuation will be listed 
separately.
10.3.4.2
Laboratory data
The number of subjects with treatment emergent (until 3 days after any temporary or 
permanent interruption of study drug) abnormal laboratory values above or below the normal 
range will be tabulated by the laboratory parameter and treatment group. 
Summary statistics including changes to baseline will be calculated by treatment group and 
visit for all quantitative laboratory parameters, e.g. for hematology, HbA1c, clinical chemistry 
and urinalysis. Geometric statistics and ratios to baseline will be presented for creatinine

instead of arithmetic statistics with changes from baseline. For eGFR the relative change will 
be displayed in addition to the absolute change from baseline.
Summary statistics for serum potassium, eGFR and serum creatinine will also be repeated by 
treatment group and visit separately for each level of the stratification factors (type of 
albuminuria, region and eGFR category). 
The following special safety parameters will be further assessed by displaying the number of 
subjects with safety events as described below by treatment group, visit and for any time on 
treatment (including unscheduled assessments) and up to 3 days after last study drug 
administration. This will also be performed by stratification factors. The summaries will be 
performed for the number of subjects with

Absolute value of serum potassium >5.5 mmol/L and >6 mmol/L 

Relative decrease from baseline in eGFR of ≥30%, ≥40%, ≥50% and ≥57%, also 
sustained decrease over 4 weeks

Absolute value of eGFR < 30 mL/min/1.73m² 
The percentage of subjects with the respective events (non-stratified) at any time 
post-baseline (including unscheduled assessments) and within 3 days after last study drug 
administration will be compared between the finerenone and the placebo treatment group by 
applying separate explorative χ² tests with continuity correction. If the expected number of 
subjects in at least 1 cell of the 2x2 contingency table is <5 (51), Fisher’s exact test will be 
applied instead of the ² test. Estimates and two-sided 95% confidence intervals will be 
provided for each treatment group and the treatment differences. Clopper Pearson confidence 
intervals will be calculated for each treatment group, while for treatment differences the exact 
unconditional confidence limits will be calculated.
10.3.4.3
Vital signs
At the corresponding visits, 3 measurements of vital signs parameters will be taken in sitting 
position with at least a 1-minute interval between each reading. Averages of 
non-missing values of these three measurements will be calculated and used for the statistical 
analysis. If only one of the planned measurements is available, this value will be used.
Vital signs values will be summarized by treatment group and visit using descriptive statistics 
including absolute changes from baseline. The analysis will be repeated for SBP stratified by 
baseline SBP >90 to <130 mmHg, 130 to <160 mmHg and ≥160 mmHg.
10.3.4.4
Weight and BMI
The values and the changes from baseline will be summarized by treatment group and visit 
using descriptive statistics for weight and BMI. 
10.3.4.5
Further safety variables
All safety variables are listed at the start of this section.  Not covered in the above sections is 
the presence or absence of events associated with hyperkalemia and renal failure. These will 
be summarized by treatment group using frequency counts.

Missing data / drop outs
A subject who has been randomized and discontinues study participation prematurely for any 
reason, either from study treatment or from follow-up, is defined as a ‘dropout’, even if 
no study drug has been taken. Dropouts will not be replaced. 
Data from subjects who prematurely terminated the study will be used to the maximum extent 
possible.
All missing or partial data will be presented in the subject data listing as they are recorded on 
the electronic eCRF.
Sensitivity analyses using other imputation methods will be performed for the primary 
endpoint.
For further information on missing data, please refer to Section 11.4.
10.4
Determination of sample size - amended
This section was changed in Amendment 3, see Section 15.1.2.41.
This is an event-driven study. A total of 1068 primary efficacy endpoint events will have a 
minimum 90% power to demonstrate superiority of finerenone to placebo using a logrank test at 
a two-sided significance level of 3.3333%, assuming a 20% relative risk reduction, i.e. a true 
hazard ratio of 0.80 (the hazard ratio that will be observed in the study will be different, i.e. 
closer to 1 due to treatment discontinuations). The study will stop when at least 1068 primary 
efficacy endpoints accrue across both treatment arms.
With an assumed treatment duration of 44 months (duration of recruitment period: 33 months, 
equal recruitment pattern during the accrual period, maximum treatment period of the last 
subject recruited: 11 months), the planned total number of subjects to be randomized is 
estimated to be 4690 subjects, assuming an annual placebo event rate of 12%, a common 
annual lost-to-follow-up rate of 0.7% in both treatment groups, an annual finerenone 
discontinuation rate of 5% and assuming that placebo discontinuation will not change the 
hazard. 4800 subjects are planned to be randomized taking a certain ramp-up during 
recruitment into account. Assuming a screening failure rate of 50%, 9600 subjects are planned 
to be screened. 
Due to the minimal effect of the interim analysis on the overall power of the study, an 
adjustment of sample size would be negligible.
The assumption of the annual placebo event rate of 12% is based on a recent analysis of the 
results from the IDNT and RENAAL trials using alternative endpoints defined by smaller 
declines in eGFR, similar to those proposed in Study 16244. Event rates were obtained from 
the respective studies in the arms where treatment would more closely resemble that in the 
placebo population of study 16244 who will be on standard of care treatment for DKD. 
Annual event rates for the composite renal endpoint range from 11-16% for these studies. The 
planned population of study 16244 will have some differences compared to IDNT and 
RENAAL, with a likely lower median UACR value but comparable mean eGFR. The 
comorbidity of diabetic retinopathy in subjects with high albuminuria may predict a higher

rate of renal events. Consequently, the assumed annual placebo event rate of 12% is assumed 
to be appropriate for this Phase III setting (10, 11). 
The calculations of the required total number of events and subjects to be randomized were 
performed using PASS 11 (52).
10.5
Planned interim analyses - amended
This section was changed in Amendment 3, see Section 15.1.2.42.
One formal interim analysis is planned when 2/3 of the required total number of primary 
efficacy endpoint events have been observed. Based on the assumptions from sample size 
determination the interim analysis will take place about 34 months after start of study 
treatment. As an event-driven trial, the actual timing of the interim analysis will depend on the 
observed event rate, the patient recruitment rate, and length of the recruitment period.
If the interim analysis shows clear and consistent benefit in the finerenone treatment group, 
the DMC may recommend early study termination. The Haybittle-Peto rule will be used to 
guide the decision regarding early stopping of the study for success: a reduction of 3 standard 
deviations in the analysis of the primary efficacy endpoint and the secondary CV composite 
endpoint at the interim analysis (two-sided p-value < 0.00270). 
If the decision will be to stop the study early for success, the final primary analyses, both for 
the primary and secondary efficacy endpoints, will be performed at an overall two-sided 
significance level of 0.270%. A group sequential design with a single interim analysis when 
2/3 of the information is available with a stopping rule of two-sided p < 0.00270 would 
require a final p < 0.04967 (p < 0.03283, p < 0.01576) to maintain the overall significance 
level at 5% (3.333%, 1.667%). Consequently, if the decision will be to continue the study 
without stopping early for success, the following testing procedure at the final analysis will 
control the overall familywise error rate at 5% according to Tang and Geller (1999) (53).

If the primary renal composite endpoint achieves statistical significance at a two-sided 
p value ≤ 0.03283 (z0.9836 = 2.134), the secondary CV endpoint will be tested at the 
two sided level of 0.04967 (z0.9752 = 1.963)

Alternatively, if the secondary CV endpoint achieves statistical significance at a two 
sided p value ≤ 0.01576 (z0.9921 = 2.414), the primary renal composite endpoint will be 
tested at the two-sided level of 0.04967 (z0.9752 = 1.963)

Only if both the renal and CV endpoints achieve formal statistical significance, the 
remaining secondary endpoints will be tested hierarchically at a two-sided level of 
0.04967 (z0.9752 = 1.963).
For a lack of efficacy, a non-binding futility approach will be utilized at the time of the 
planned interim analysis. If the conditional probability of rejecting the null hypothesis for the 
primary comparison, given the assumed and current event rates, falls to an unacceptably low 
level (as will be specified in the DMC Charter), the DMC may consider recommending early 
termination of the study.

The Executive Committee will oversee overall blinded event rates to ensure that they meet 
protocol projections. If overall event rates are lower than expected, consideration will be 
given to altering the trial design, such as increasing the sample size or extending the study 
duration without knowledge of any treatment effect.

Data handling and quality assurance
11.1
Data recording
The data collection tool for this study will be a validated electronic data capture system called 
RAVE. Subject data necessary for analysis and reporting will be entered/transmitted into a 
validated database or data system. 
Data required according to this protocol will be recorded by investigational site personnel via 
data entry into the internet based EDC software system RAVE, which Bayer has licensed 
from Medidata Solutions Worldwide. RAVE has been validated by Medidata Solutions 
Worldwide and Bayer for use in its clinical studies. RAVE allows for the application of 
software logic to set-up data entry screens and data checks to ensure the completeness and 
accuracy of the data entered by the site personnel. Bayer extensively applies the logic to 
ensure data are complete and reflect the clinical data requirements of the study. Data queries 
resulting from the application of the software logic are resolved by the site personnel. The 
data are stored at a secure host facility maintained by Medidata Solutions Worldwide and 
transferred on a periodic basis to Bayer's internal computer system via a secure Virtual Private 
Network.
All access to the RAVE system is through a password-protected security system that is part of 
the RAVE software. All internal Bayer and external investigator site personnel seeking access 
must go through a thorough RAVE training process before they are granted access to RAVE 
for use in Bayer's clinical studies. Training records are maintained.
All personnel with access to the RAVE system are supported by a Service Desk staffed with 
trained personnel to answer questions and ensure access is maintained such that data entry can 
proceed in a timely manner.
The RAVE System contains a system-generated audit trail that captures any changes made to 
a data field, including who made the change, why the change was made and the date and time 
it was made. This information is available both at the investigator’s site and at Bayer. Data 
entries made in the RAVE EDC screens are supported by source documents maintained for all 
subjects enrolled in this study.
Source documentation
It is the expectation of the sponsor that key data entered into the eCRF has source 
documentation available at the site.
Study-specific data (race and ethnic group) may be entered directly into the CRF, without 
availability of corresponding source documentation.  For all other data, source documentation 
must be available at the site.

The site must implement processes to ensure availability of all required source 
documentation. A source document checklist (not part of this protocol) will be used at the site 
to identify the source data for key data points collected and the monitor will work with the site 
to complete this.
Data recorded from screening failures
Data of ‘only screened subjects’ will be recorded at least as source data, as far as the reason 
for the premature discontinuation is identifiable. At minimum, the following data should be 
recorded in the eCRF:
Demographic information (subject number; year of birth / age; sex; if applicable race / 
ethnicity)
Date of informed consent
Reason for premature discontinuation
Date of last visit.
These data will be transferred to the respective database.
11.2
Monitoring
In accordance with applicable regulations, GCP, and sponsor’s/CRO’s procedures, monitors 
will contact the site prior to the start of the study to review with the site staff the protocol, 
study requirements, and their responsibilities to satisfy regulatory, ethical, and sponsor’s 
requirements. When reviewing data collection procedures, the discussion will also include 
identification and documentation of source data items.
The sponsor/designee will monitor the site activity to verify that the:

Data are authentic, accurate and complete. 

Safety and rights of subjects are being protected

Study is conducted in accordance with the currently approved protocol 
(including study treatment being used in accordance with the protocol)

Any other study agreements, GCP, and all applicable regulatory requirements are met.
The investigator and the head of the medical institution (where applicable) agrees to allow the 
monitor direct access to all relevant documents.
11.3
Data processing
Data will be collected as described in Section 11.1. Clinical data management will be 
performed in accordance with applicable sponsor’s/CRO’s standards and data cleaning 
procedures. This is applicable for data recorded on eCRF as well as for data from other 
sources (e.g. IxRS, laboratory, adjudication committees).

11.4
Missing data 
All efforts will be made to collect complete data for all subjects randomized in this study. 
Subjects will be followed until the end of the study, and all required data will be collected, 
regardless of their compliance with study medication use or visit schedule.
After randomization, study drug discontinuation for any reason does not constitute withdrawal 
from the study and should not lead to the subject being withdrawn from the study. On the 
contrary, even subjects who have stopped taking study drug are expected to attend all the 
protocol specified study visits and will be encouraged to perform all assessments as stipulated 
in the visit schedule.
If it is not possible for a subject who has withdrawn from study drug to attend any visit(s) in 
person, the site staff will keep in touch with the subject by means of phone contact to the 
subject himself/herself, or to a person pre-designated by the subject, in accordance with the 
subject’s study visit schedule. Data will continue to be collected about the subject’s health 
status, including information on developing of renal or CV complications and vital status. 
This information may be provided either by the subject himself/herself, his/her general 
practitioner or a family relative (if allowed in the respective country). Data, such as 
information on survival and potential protocol-specified endpoints, might be also collected 
from a healthcare provider, from public or medical records, or other sources as available 
according to local guidelines and as allowed by local regulations. These data will be collected 
until the study is concluded, even if the subject no longer attends study visits in person, 
unless the subject withdrew consent and did not agree to release further information.
When an event date is not known, the site investigator will be asked to provide a best-estimate 
as to when the event occurred. Even though the exact date of an event is unknown, the 
investigator often has some information that would give an approximate date (e.g. the 
first week of a month, the fall of a year, or the middle of a particular year) or at least the 
date when the subject was last seen or contacted. This information can be meaningfully 
incorporated into the estimated date recorded, as this is likely to be closer to the true date than 
any produced by an uninformed computer algorithm. This estimated date should be the 
middle date within the period that the event is known to have occurred. If the event is known 
to have occurred in the first week of a month, then the date in the middle of that week should 
be recorded as the estimate. If it occurred in the fall of a year, then the middle date in the fall 
is the appropriate estimate. If no information is known, then the date in the middle of the 
plausible time period should be given, based on the last contact with the subject prior to the 
event and the date of contact when information about the event was known.
Data from subjects who prematurely terminate the study will be used to the maximum extent 
possible. All missing or partial data will be presented in the subject data listing as they are 
recorded on the eCRF. Data are collected primarily through an EDC system, which allows 
ongoing data entry and monitoring.

For those subjects who withdraw consent, sensitivity analyses will be performed to assess the 
impact of potential informative censoring of such subjects. These will include the use of 
different imputation rules for considering subjects without an event of the primary composite 
endpoint as having an event or being censored.
11.5
Audit and inspection
To ensure compliance with GCP and regulatory requirements, a member of the sponsor’s (or a 
designated CRO’s) quality assurance unit may arrange to conduct an audit to assess the 
performance of the study at the study site and of the study documents originating there. The 
investigator/institution will be informed of the audit outcome.
In addition, inspections by regulatory health authority representatives and IEC(s)/IRB(s) are 
possible. The investigator should notify the sponsor immediately of any such inspection.
The investigator/institution agrees to allow the auditor or inspector direct access to all relevant 
documents and allocate his/her time and the time of his/her staff to the auditor/inspector to 
discuss findings and any issues. Audits and inspections may occur at any time during or after 
completion of the study.
11.6
Archiving
Essential documents shall be archived safely and securely in such a way that ensures that they 
are readily available upon authorities’ request.
Patient (hospital) files will be archived according to local regulations and in accordance with 
the maximum period of time permitted by the hospital, institution or private practice. Where 
the archiving procedures do not meet the minimum timelines required by the sponsor, 
alternative arrangements must be made to ensure the availability of the source documents for 
the required period.
The investigator/institution notifies the sponsor if the archival arrangements change (e.g. 
relocation or transfer of ownership).
The investigator site file is not to be destroyed without the sponsor’s approval.
The contract with the investigator/institution will contain all regulations relevant for the study site.

Premature termination of the study
The sponsor has the right to close this study (or, if applicable, individual segments thereof 
[e.g. centers]) at any time, which may be due but not limited to the following reasons: 
If risk-benefit ratio becomes unacceptable owing to, for example,
Safety findings from this study (e.g. SAEs)
Results of any interim analysis
Results of parallel clinical studies
Results of parallel animal studies 
(on e.g. toxicity, teratogenicity, carcinogenicity or reproduction toxicity).
If the study conduct (e.g. recruitment rate; drop-out rate; data quality; protocol compliance) 
does not suggest a proper completion of the trial within a reasonable time frame.
The investigator has the right to close his/her center at any time.
For any of the above closures, the following applies:
Closures should occur only after consultation between involved parties. Final decision

13.1.1
Executive Committee
The Executive Committee, which consists of external experts in the area of nephrology, 
diabetology and cardiology, will ensure the overarching integrity of the study. 
The Executive Committee will be established for Study 16244 and Study 17530. The 
committee’s responsibilities include the following: 

Review feedback from the independent DMC

Input into the Clinical Event Committee (CEC) charter

Provision of recommendations regarding sub-studies and amendments to the protocol

Contribution to and oversight of publications and communication of study results

Projecting study termination, and other study-related activities as appropriate

Overseeing overall blinded event rates to ensure that they meet protocol projections.
Decisions will be made by consensus; in the absence of consensus, the co-Chairs of the 
Executive Committee will provide their recommendation to the Sponsor for final determination.
13.1.2
Clinical Event Committee (CEC)
A Clinical Event Committee (CEC), blinded to study treatment assignment, will adjudicate all 
events that could potentially fulfill the criteria for the primary, secondary or other endpoints 
during the study.

Page:  99 of 139
The CEC Charter will describe the roles and responsibilities of the CEC and define the events to 
be adjudicated and the manner in which they will be adjudicated. The CEC will judge whether 
an event meets the predetermined definitions. The co-Chairs of the CEC will be members of the 
Executive Committee established for Study 16244 and Study 17530.
All of the endpoint events shown in Table 13–1 will be reported to the CEC.
Table 13–1
Endpoint events to be reported to the Clinical Event Committee (CEC)
●  Kidney failure
●  Decrease of eGFR of ≥40% from baseline, confirmed by at least one additional standardized 
measurement at least 4 weeks after the initial measurement
●  Decrease of eGFR of ≥57% from baseline, confirmed by at least one additional standardized 
measurement at least 4 weeks after the initial measurement
●  Decrease of eGFR to less than 15 mL/min/1.73m², confirmed by at least one additional 
standardized measurement at least 4 weeks after the initial measurement
●  CV and renal death events
●  Non-fatal myocardial infarction
●  Non-fatal stroke
●  Hospitalization for heart failure
●  Other CV hospitalization
●  New onset of atrial fibrillation or atrial flutter
Note:
Other endpoints of interest may be added. These will be specified in the CEC Charter.
The CEC will be responsible for classifying all death and hospitalization events and for 
determining whether pre-specified endpoint criteria were met for CV, renal or other fatal and 
non-fatal events. Sites are instructed to take a conservative approach when reporting 
endpoints; if the investigator suspects an endpoint may have occurred, it is best to report the 
event to the CEC for a final determination.
Reporting guidelines for AEs and SAEs as outlined in Sections 9.6.1.1 and 9.6.1.4 must 
be followed if the event is not a defined endpoint (see Table 13–1).

13.1.3
Data Monitoring Committee (DMC)
Ongoing safety monitoring during the conduct of the study will be performed by an external 
and independent DMC. An independent statistical analysis center (SAC) will be involved in 
processing unblinded safety data for the DMC. Analysis periods and procedures will be 
defined in an operational charter (DMC charter) filed in the study file. 
Outcome events as defined in Section 9.6.1.3.1 will not be reported as AEs or SAEs by the 
investigators; however, they will be collected in the eCRF. The independent DMC will 
periodically review and assess all outcome events as well as safety data from the study for 
imbalances in safety outcomes in an unblinded manner. It is believed that in this way, patient 
safety can continue to be monitored throughout the duration of the trial, and the integrity of the 
study maintained. If unexpected safety issues are identified, specific amendments will be 
implemented based on the recommendation of the DMC.
Following data review, the DMC will provide written recommendations that will be 
transferred to the chairmen of the Executive Committee and Bayer. DMC opinions and 
recommendations will be notified by Bayer as soon as possible to the competent authorities 
and the IECs where they qualify for expedited reporting.
13.1.4
Steering Committee 
The Steering Committee will consist of country representative(s) and will be led by the 
Executive Committee. The Steering Committee will be blinded to the study data while the 
trial is ongoing. Their main responsibilities are as follows: 

Provide input to protocol-related issues and protocol amendments that may arise 
during the course of the study

Oversee study progress and provide recommendations to Executive Committee in 
regards to any necessary modifications that may be required in study conduct or study 
monitoring

Transmission of information to individual investigators

Serve as resource for scientific review of sub-studies, publications, presentations
and/or educational material as applicable.
13.2
Funding and financial disclosure
Funding
This study will be funded by its sponsor.

13.3
Ethical and legal conduct of the study
The procedures set out in this protocol, pertaining to the conduct, evaluation, and 
documentation of this study, are designed to ensure that the sponsor and investigator abide by 
Good Clinical Practice (GCP) guidelines and the guiding principles detailed in the 
Declaration of Helsinki. The study will also be carried out in keeping with applicable local 
law(s) and regulation(s).
Documented approval from appropriate IEC(s)/IRBs will be obtained for all participating 
centers/countries before start of the study, according to GCP, local laws, regulations and 
organizations. When necessary, an extension, amendment or renewal of the IEC/IRB approval 
must be obtained and also forwarded to the sponsor. The responsible unit (e.g. IEC/IRB, head 
of the study center/medical institution) must supply to the sponsor, upon request, a list of the 
EC/IRB members involved in the vote and a statement to confirm that the IEC/IRB is 
organized and operates according to GCP and applicable laws and regulations.
Strict adherence to all specifications laid down in this protocol is required for all aspects of 
study conduct; the investigator may not modify or alter the procedures described in this 
protocol. 
Modifications to the study protocol will not be implemented by either the sponsor or the 
investigator without agreement by both parties. However, the investigator or the sponsor may 
implement a deviation from, or a change of, the protocol to eliminate an immediate hazard(s) 
to the trial subjects without prior IEC/IRB/sponsor approval/favorable opinion. As soon as 
possible, the implemented deviation or change, the reasons for it and if appropriate the 
proposed protocol amendment should be submitted to the IEC/IRB/head of medical 
institution/sponsor. Any deviations from the protocol must be explained and documented by 
the investigator.
Details on discontinuation of the entire study or parts thereof can be found in Section 12.
13.4
Subject information and consent
All relevant information on the study will be summarized in an integrated subject information 
sheet and informed consent form provided by the sponsor or the study center. A sample 
subject information and informed consent form will be provided as a document separate to 
this protocol.
Based on this subject information sheet, the investigator or designee will explain all relevant 
aspects of the study to each subject / legal representative or proxy consenter (if the subject is 
under legal protection), prior to his/her entry into the study (i.e. before any examinations and 
procedures associated with the selection for the study are performed or any study-specific data 
is recorded on study-specific forms).
The investigator will also mention that written approval of the IRB/IEC has been obtained.

Each subject / legal representative or proxy consenter will be informed about the following 
aspects of premature withdrawal:

Each subject has the right to withdraw from the study at any time without any 
disadvantage and without having to provide reasons for this decision. 

The subject’s consent covers end-of-study examinations as specified in the visit 
description described in Section 9.2 to be conducted after withdrawal of consent. 

The subject’s data that have been collected until the time of withdrawal will be 
retained and statistically analyzed in accordance with the statistical analysis plan. 

Subject-specific data on the basis of material obtained before withdrawal may be 
generated after withdrawal (e.g. image reading, analysis of biological specimen such 
as blood, urine or tissues); these data would also be retained and statistically analyzed 
in accordance with the statistical analysis plan. The subject has the right to object to 
the generation and processing of this post-withdrawal data. For this, he/she needs to 
sign a corresponding declaration of objection; alternatively, the subject’s oral 
objection may be documented in the subject’s source data.
Each subject / legal representative or proxy consenter will have ample time and opportunity to 
ask questions.
Only if the subject / legal representative or proxy consenter voluntarily agrees to sign the 
informed consent form and has done so, may he/she enter the study. Additionally, the 
investigator will personally sign and date the form. The subject / legal representative or proxy 
consenter will receive a copy of the signed and dated form.
The signed informed consent statement is to remain in the investigator site file or, if locally 
required, in the subject’s note/file of the medical institution.
In the event that informed consent is obtained on the date that baseline study procedures are 
performed, the study record or subject’s clinical record must clearly show that informed 
consent was obtained prior to these procedures.

If the subject is not capable of providing a signature, a verbal statement of consent can 
also be given in the presence of an impartial witness (independent of the sponsor and 
the investigator). This is to be documented by a signature from the informing 
physician as well as by a signature from the witness.

For adults under legal protection, consent shall be given by the legal guardian(s). The 
consent of an adult under legal protection shall also be requested where such a person 
is able to express his/her own will. His/her refusal or the withdrawal of his/her consent 
may not be disregarded.
The informed consent form and any other written information provided to subjects / legal 
representatives or proxy consenters will be revised whenever important new information 
becomes available that may be relevant to the subject’s consent, or there is an amendment to 
the protocol that necessitates a change to the content of the subject information and / or the 
written informed consent form. The investigator will inform the subject / legal representative

or proxy consenter of changes in a timely manner and will ask the subject to confirm his/her 
participation in the study by signing the revised informed consent form. Any revised written 
informed consent form and written information must receive the IEC/IRB`s approval / 
favorable opinion in advance of use.
13.5
Publication policy and use of data
The sponsor has made the information regarding the study protocol publicly available on the 
internet at www.clinicaltrials.gov. 
All data and results and all intellectual property rights in the data and results derived from the 
study will be the property of the sponsor who may utilize them in various ways, such as for 
submission to government regulatory authorities or disclosure to other investigators.
Regarding public disclosure of study results, the sponsor will fulfill its obligations according 
to all applicable laws and regulations. The sponsor is interested in the publication of the 
results of every study it performs. 
The sponsor recognizes the right of the investigator to publish the results upon completion of 
the study. However, the investigator, whilst free to utilize study data derived from his/her 
center for scientific purposes, must obtain written consent of the sponsor on the intended 
publication manuscript before its submission. To this end, the investigator must send a draft 
of the publication manuscript to the sponsor within a time period specified in the contract. 
The sponsor will review the manuscript promptly and will discuss its content with the 
investigator to reach a mutually agreeable final manuscript. 
13.6
Compensation for health damage of subjects / insurance
The sponsor maintains clinical trial insurance coverage for this study in accordance with the 
laws and regulations of the country in which the study is performed.
13.7
Confidentiality
All records identifying the subject will be kept confidential and, to the extent permitted by the 
applicable laws and/or regulations, will not be made publicly available.
Subject names will not be supplied to the sponsor. Only the subject number will be recorded 
in the eCRF, and if the subject name appears on any other document (e.g. pathologist report), 
it must be obliterated before a copy of the document is supplied to the sponsor. Study findings 
stored on a computer will be stored in accordance with local data protection laws. As part of 
the informed consent process, the subjects will be informed in writing that representatives of 
the sponsor, IEC/IRB, or regulatory authorities may inspect their medical records to verify the 
information collected, and that all personal information made available for inspection will be 
handled in strictest confidence and in accordance with local data protection laws.

15. Protocol amendments
15.1
Amendment 3
Amendment 3 is the first global amendment dated 02 MAY 2017.  The following is an 
overview of the changes made to the original Protocol Version 1.0.
15.1.1
Overview of changes to the study
The original protocol for this study was amended for the following reasons:
1) To account for the lower than expected recruitment rate, the duration of study and the 
number of sites required worldwide were increased.
2) To allow re-screening at an earlier stage and even if the reason for initial screen failure 
was an elevated blood potassium value, the re-screening rules were amended.
3) To allow randomization of patients with a recent CVD episode (i.e. those suffering 
from stroke, transient ischemic cerebral attack, acute coronary syndrome or 
hospitalization for worsening heart failure in the last 30 days prior to the Screening 
visit), the respective Exclusion criterion (#7) was modified.
4) In order to allow up-titration of study drug at any time during the study (from Visit 2 
onwards), the instructions for up-titration were modified. Additionally, a requirement 
to specify the reason for not dispensing the 20 mg dose in the eCRF was added.
5) The recommended blood pressure targets after randomization were updated according 
to the most recent literature.
6) The definition of the endpoint “kidney failure” was added.
7) Administrative changes: 
Sponsor name was updated (Bayer AG became the sponsor for ongoing Bayer 
HealthCare AG sponsored studies on 1st July 2016), Sponsor for US territory was 
added, contact details for Sponsor’s medical expert were updated, and terminology 
changes due to updated Operating Instructions (“protocol deviation” was replaced by 
“validity finding”) were made. 
8) To improve clarity and correct typographical errors or inconsistencies.

Changes to the protocol text
In the sections on changes to the protocol text, all protocol sections affected by the respective 
amendment are detailed; the sequence of the sections follows the structure of the most recent 
previous protocol version. As applicable, changes to the protocol text are highlighted as 
follows:
Addition of a whole new portion
Brief identification of the new portion
Removal of a whole portion
Complete display of the removed portion, formatted 
as crossed out
Editing of an existing portion
Comparative presentation of “old text” versus “new 
text”, with “old text” referring to the most recent 
previous protocol version. Deletions are crossed out
in the “old text”. Additions are underlined in the 
“new text”. 
Tables / figures
The term “amended” is added to the caption.
Terminological changes
Brief specification of the terminological change
Thus, in this section, a terminological change (e.g. 
“period” versus “epoch”) is defined only once, 
without displaying “old text” versus “new text” for 
each appearance.

Patients from approximately 650 study centers worldwide will be randomized in a 1:1 ratio to 
either finerenone or placebo in addition to SoC therapy. Assuming a screening failure rate of 
approximately 50%, 9600 patients will have to be screened to randomize approximately 
4800 patients. 
The anticipated duration of the study is approximately 3.25 years: this includes an anticipated 
recruitment period of 2 years followed by a study drug treatment period of 1.25 years after the 
enrolment of the last patient into the trial. However, as an event-driven trial, the actual length

Subjects with written informed consent who complete the Run-in Visit and meet all eligibility
criteria will be enrolled into a mandatory Run-in Period, the purpose of which is to ensure that 
the subject’s SoC therapy including treatment with ACEIs or ARBs is optimized and that all 
inclusion and exclusion criteria are met at the Screening Visit. 
[…]
Screening Period (up to 2 weeks)
At the end of the Run-in Period, a Screening Visit to confirm the subject’s eligibility will take 
place within ≤ 2 weeks prior to the planned randomization. At this visit, it will be assessed 
whether the subject still meets all the inclusion and none of the exclusion criteria.
[…]
Treatment Period
[…]
There will be up to 4 planned visits (including randomization at Visit 1) in the first 4 months; 
thereafter visits will take place every 4 months until the end of the study. Study drug dose can 
be up-titrated at scheduled visits starting from Visit 2 (Month 1) onwards or down-titrated at 
any point (even between scheduled visits); guidance on dose adjustment is provided in 
Section 7.4. Subjects may be seen at any time throughout the study, in addition to scheduled 
visits, at the discretion of the investigator.
[…]
End of study
[…]
All subjects who had withdrawn consent can be followed up for vital status if they do not sign 
the ‘Declaration of Objection’ form. In addition, vital status can be obtained by the 
investigator from publicly available data sources. The collection of vital status must be 
obtained within the timelines provided by Bayer.

Up- and down-titration of study drug
The investigator is encouraged to up-titrate the dose of study drug at any time once the patient 
has been on a stable dose for 4 weeks (± 7 days) (e.g. from Visit 2 onwards for patient starting 
study drug on the lower dose) either at a regular visit or an Up-titration Visit. Up-titration can

up-titrated again based on the rules provided above. […]
Subsequent to an up-titration or re-start of study drug after interruption of study drug intake 
for more than 7 days, the investigator should perform an Up-titration Visit 4 weeks (±7 days) 
after titration or restart, in order to monitor potassium levels and renal function (see Table 9-
1). If a regular study visit will be scheduled to take place 4 weeks 
(± 7 days) after up-titration, the monitoring of potassium and renal function is assured and no 
Up-titration Visit has to be performed in addition. […]

Kidney failure is defined as either the occurrence of ESRD or an eGFR of less than 15 
mL/min/1.73 m², confirmed by a second measurement at the earliest 4 weeks after the initial 
measurement.  ESRD is defined as the initiation of chronic dialysis (haemo- or peritoneal-
dialysis) for at least 90 days or renal transplantation. In addition, the eGFR threshold of 15 
mL/min/1.73 m² is consistent with the definition of kidney failure from KDIGO (Kidney 
Disease: Improving Global Outcomes)(3) and was chosen in order to include an objective 
component to the endpoint because the decision to initiate dialysis therapy or kidney 
transplantation may be affected by factors other than the eGFR. All other definitions of 
individual endpoints (e.g. CV death) will be provided in the Endpoint Manual.

15.1.2.41 Section 10.4 Determination of sample size
Old text:
This is an event-driven study. A total of 1061 primary efficacy endpoint events will have 
90% power to demonstrate superiority of finerenone to placebo using a logrank test at a two-
sided significance level of 3.3333%, assuming a 20% relative risk reduction, i.e. a true hazard 
ratio of 0.80 (the hazard ratio that will be observed in the study will be different, i.e. closer to 1 
due to treatment discontinuations). The study will stop when at least 1061 primary efficacy 
endpoints accrue across both treatment arms.
With an assumed study duration of 39 months (duration of recruitment period: 24 months, 
equal recruitment pattern during the accrual period, maximum treatment period of the last 
subject recruited: 15 months), the planned total number of subjects to be randomized is 
estimated to be 4701 subjects, assuming an annual placebo event rate of 12%, a common 
annual lost-to-follow-up rate of 0.7% in both treatment groups, an annual finerenone 
discontinuation rate of 5% and assuming that placebo discontinuation will not change the 
hazard. [...]
The assumption of the annual placebo event rate of 12% is based on the results from the 
MICRO-HOPE, RENAAL, IDNT, ALTITUDE and SAVOR-TIMI 53 trials. The latter 2 are 
more recent studies. Event rates were obtained from the respective studies in the arms where 
treatment would more closely resemble that in the placebo population of the CV-DKD study 
who will be on standard of care treatment for DKD. Annual event rates for the composite CV
endpoint range from 7-10% for older studies and 5-6% for more recent studies. As the 
anticipated population of Study 16244 will be more enriched for CV outcomes than 
ALTITUDE and SAVOR-TIMI 53 with regard to the requirement for CV history or CV risk 
factors for subjects with high albuminuria, a likely lower mean eGFR and higher median 
UACR value, the assumed annual placebo event rate of 12% is assumed to be appropriate for 
this Phase III setting.

The assumption of the annual placebo event rate of 12% is based on a recent analysis of the 
results from the IDNT and RENAAL trials using alternative endpoints defined by smaller 
declines in eGFR, similar to those proposed in Study 16244. Event rates were obtained from 
the respective studies in the arms where treatment would more closely resemble that in the 
placebo population of study 16244 who will be on standard of care treatment for DKD. 
Annual event rates for the composite renal endpoint range from 11-16% for these studies. The 
planned population of study 16244 will have some differences compared to IDNT and 
RENAAL, with a likely lower median UACR value but comparable mean eGFR. The 
comorbidity of diabetic retinopathy in subjects with high albuminuria may predict a higher 
rate of renal events. Consequently, the assumed annual placebo event rate of 12% is assumed 
to be appropriate for this Phase III setting
15.1.2.42 Section 10.5 Planned interim analyses
Old text:
One formal interim analysis is planned when 2/3 (707) of the required total number of 
primary efficacy endpoint events have been observed. Based on the assumptions from sample 
size determination the interim analysis will take place about 30 months after study initiation.
New text:
One formal interim analysis is planned when 2/3 of the required total number of primary 
efficacy endpoint events have been observed. Based on the assumptions from sample size 
determination the interim analysis will take place about 34 months after start of study 
treatment. As an event-driven trial, the actual timing of the interim analysis will depend on the 
observed event rate, the patient recruitment rate, and length of the recruitment period.

HR-QoL questionnaires
KDQOL-36 is a specific measure of health-related quality of life for CKD that includes 
effects and burden of kidney disease as well as physical and mental health scores. 
Two forms of the KDQOL exist: the KDQOL-SF and the KDQOL-36. Both were developed
by the Kidney Disease Quality of Life Working Group at RAND Corporation. The 
KDQOL-SF is based on the SF-36 with additional questions specific to kidney disease 
concerning symptoms and problems, effects of kidney disease on daily life, burden of 
kidney disease, cognitive function, work status, sexual function, quality of social interaction, 
and sleep (55). It was developed for use with a dialysis patient population but it has also been 
found to be valid and reliable in a kidney transplant patient population (56). Studies using the 
KDQOL revealed that psychological factors, including depression, were a much stronger 
determinant of quality of life than biological measures like dialysis adequacy (57). While the 
KDQOL-SF has 134 questions the shorter form KDQOL-36 consists of 36 questions and 
contains the SF-12. The items of the KDQOL-36 are grouped as shown in Table 16–4.
The EQ-5D-5L was introduced in 2005. The EQ-5D-5L still consists of 2 pages: the 
EQ-5D-5L descriptive system and the EQ Visual Analogue scale (EQ VAS). 
The descriptive system comprises the same 5 dimensions as the EQ- 5D-3L (mobility, 
self-care, usual activities, pain/discomfort, anxiety/depression). However, each dimension 
now has 5 levels: no problems, slight problems, moderate problems, severe problems, and 
extreme problems.
