Title of trial:
A double-blind, randomised, placebo-controlled, parallel group trial 
to evaluate the efficacy and safety of empagliflozin and linagliptin 
over 26 weeks, with a double-blind active treatment safety extension 
period up to 52 weeks, in children and adolescents with type 2 
diabetes mellitus
Coordinating
Investigator:
Trial site(s):
Multi-centre trial conducted in approximately 15-20 countries
Clinical phase:
III
Rationale:
DINAMOTM (main study)
The trial is planned to be conducted in children and adolescents 
treated with diet and exercise and metformin and/or insulin 
background. Patients not tolerating metformin and treated with diet 
and exercise only have an unmet medical need for oral antidiabetic 
drugs beside metformin and are expected to highly benefit from 
inclusion into this trial.
DINAMOTM Mono:
The TODAY study has shown that the majority of youth with 
T2DM can be effectively treated with metformin monotherapy 
during the first 12 months of the disease. However, the TODAY 
study also demonstrated that metformin monotherapy fails to 
maintain HbA1c < 8.0% in most adolescents during the second year 
of treatment, even in the face of substantial residual endogenous 
insulin. Therefore, studies are warranted to assess whether oral 
antidiabetic medications can either replace metformin as initial 
therapy or whether a patients can switch from metformin

monotherapy in case of metformin failure to another oral 
antidiabetic medication instead of initiation of insulin therapy. 
Objective(s):
DINAMOTM (main study)
The objective of this study is to assess the efficacy and safety of an 
empagliflozin dosing regimen and one dose of linagliptin versus 
placebo after 26 weeks of treatment in children and adolescents with 
type 2 diabetes mellitus treated with metformin and/or insulin or 
who are not tolerating metformin. In addition, this study will assess 
long term safety of empagliflozin and linagliptin after 52 weeks of 
treatment.
DINAMOTM Mono (ancillary study)
The objective of this study is to explore the effect of an 
empagliflozin dosing regimen and one dose of linagliptin as 
Monotherapy in children and adolescents with type 2 diabetes 
mellitus.
Methodology:
Multicentre, randomised, double-blind, placebo-controlled and 
parallel group design of 3 treatment arms (placebo, linagliptin 5 mg, 
empagliflozin 10 mg) over 26 weeks with a possible dose increase 
of empagliflozin 10 mg to 25 mg at Week 14 in patients not 
achieving HbA1c < 7.0% at Week 12 and a double-blind active 
treatment safety extension period up to 52 weeks. 
Patients on placebo will be re-randomised at Week 26 to receive 
either linagliptin or one of the empagliflozin doses (empagliflozin 
10 mg or 25 mg). Since patients and investigators will stay blinded, 
investigators will have to perform an IRT call for all patients at 
Week 14 and Week 26 in order to get new trial medication kits 
assigned.

Statistical methods:
DINAMOTM:
The primary endpoint will be analysed using an effectiveness
“wash-out” approach.
The “wash-out” approach will be based on an analysis of covariance 
(ANCOVA) model with baseline HbA1c as a continuous covariate, 
and with categorical covariates for treatment and age. The effect of 
linagliptin and of empagliflozin will be compared to placebo at the 
overall alpha level of 5% using the Hochberg method to account for 
multiple testing. The analysis will be based on all randomised
patients who are treated with at least one dose of study drug and 
have a baseline HbA1c value. All available HbA1c measurements 
up to Week 26 will be included regardless of adherence to treatment 
or the use of rescue medication. Patients will be assigned to the 
treatment they were randomised to at the initial randomisation.
After achieving statistically significant results for both comparisons 
in the “wash-out” approach, a secondary family of hypotheses 
comparing the individual empagliflozin doses versus placebo will be 
tested using “ inverse probability weighting” approach. The first 
analysis is the comparison of empagliflozin versus placebo in a 
regimen starting on empagliflozin 10 mg and either having a dose 
increase in patients who are not at glycaemic target at Week 12 to 
empagliflozin 25 mg, or continue with empagliflozin 10 mg who are 
at glycaemic target at Week 12 and the second analysis is the 
comparison of empagliflozin versus placebo using only 
empagliflozin 10 mg regardless whether the patients are responder 
or non-responder at Week 12. These analyses will be hierarchically
tested in a confirmatory setting.

The secondary endpoint of change in FPG from baseline to the end 
of 26 weeks will be analysed using an ANCOVA model including 
treatment as a fixed classification effect, baseline FPG as a linear 
covariate, and age as a categorical covariate.
The other secondary endpoints will be analysed based on a restricted 
maximum likelihood (REML) approach using mixed effects model 
for repeated measurements (MMRM). The analyses will include the 
fixed categorical effects of treatment, visit, and treatment by visit 
interaction, as well as the categorical covariate age and the 
continuous, fixed covariates of baseline and baseline by visit 
interaction. An unstructured covariance structure will be used to 
model the within-patient measurements. The analysis will be based 
on all randomised patients who are treated with at least one dose of 
study drug and have a baseline HbA1c value. 
The proportion of patients who achieve HbA1c < 7.0% and < 6.5% 
at the end of 26 weeks will be determined per treatment group and 
the risk difference of active treatments versus placebo will be 
determined and assessed by an exact 2-sided 95% confidence 
interval.
DINAMOTM Mono:
The primary endpoint analysis will be a comparison of the treatment 
failure rates of linagliptin 5 mg, pooled empagliflozin and placebo. 
The risk difference of active treatments versus placebo will be 
determined and assessed by an exact 2-sided 90% confidence 
interval based on the method of Chan and Zhang. Patients will be 
assigned to the treatment they were randomised to at the initial 
randomisation.
The secondary endpoint of time to treatment failure will be analysed 
and graphically described by Kaplan-Meier estimates up to the

planned end of the study. A descriptive Log-rank test will compare 
the linagliptin group and the empagliflozin group versus the placebo 
group individually up to Week 26.
The change in HbA1c from baseline to the end of 26 week will be 
analysed based on a REML approach using MMRM to access the 
effectiveness and efficacy.
The change in HbA1c from baseline to the end of 26 week will also 
be analysed using an ANCOVA model including treatment as a 
fixed classification effect, baseline HbA1c as a linear covariate, and 
age as a categorical covariate. The secondary endpoints of change in
FPG, body weight, SBP and DBP from baseline to the end of 26 
week will be analysed in the same way as DINAMOTM with the 
DINAMOTM Mono data.
The proportion of patients who achieve HbA1c < 7.0% and < 6.5%
at the end of 26 week will be determined per treatment group and 
the risk difference of active treatments versus placebo will be 
determined and assessed by an exact 2-sided 90% confidence 
interval.

2
Visits to be performed in a fasted state (overnight fast for at least 8 hours).
3
This visit could be either on-site visit or ambulatory visit (nurse/health care professional/validated courier to be assigned for delivering the trial medications at home and retrieving the 
previous ones dispensed at Visit 4A) as per the investigator’s decision. In case of ambulatory visit not performed by a site representative, a phone contact by the investigator or a site staff 
representative is required to check any new adverse event or concomitant therapy. 
4
Additional interactions (phone contact, text messaging or emails, as deemed appropriate) with the patient will be performed a day or two after randomised treatment started and then after 
2, 8, 18, 22, 34, 38, 46 and 50 weeks of treatment. Visits 3, 4A, 6, 7, 9 can be done remotely/by telephone/telemedicine under exceptional circumstances due to the Corona Virus Disease-
year 2019 (COVID-19) pandemic. Reasons a remote/telephone/telemedicine visit may be performed may include confirmed or suspected COVID-19 infection or unwillingness to return 
to the investigator site due to concerns of COVID-19 exposure.
5
If a patient discontinues treatment early, an immediate End of Treatment (EOT) visit would be conducted. 
6
For patients with Tanner stage V at Visit 2, further assessment is not required at the subsequent visits.
7
Laboratory tests at Visit 1A include TSH, liver enzymes, alkaline phosphatase, serum creatinine, cystatine C, haemoglobin and haematocrit only in addition to HbA1c and C-peptide and 
do not need to be collected in a fasted state.
8
Blood samples for pharmacokinetic analysis will be collected within 30 minutes prior to drug administration at site (and preferably approximately 24 hours after drug administration on 
the previous day) and 1.5h ± 15 min after drug administration.
9
IGF-1 and IGF-BP3 will not be measured at this Visit.
10
Blood sample for DPP-4 activity measurement will be collected within 30 minutes prior to trial drug administration.
11
Daily blood ketone measurements in the first 4 weeks of treatment and the 4 subsequent weeks after Visit 5; otherwise at least 3 times per week and in case of intercurrent illness/stress or 
if deemed necessary by the investigator. In addition, blood ketone levels will be checked by using the meter at clinic visits.
12
Patients who complete an early End of Treatment visit and do not accept to attend all remaining planned visits will be contacted for vital status collection at Week 55. This can be done by 
phone.
13
Patients who discontinue treatment early should attend Visit 9 at Week 55 in person or by telephone if agreed. At minimum, data on adverse events, concomitant therapies, and vital status 
should be collected at Visit 9 at Week 55. 
14
Vital signs, weight, and local laboratory testing is allowed for Visits 3, 4A, 6, 7, 9 under exceptional circumstances due to the COVID-19 pandemic.
15
Study procedure for Visits 3, 4A, 6, 7, 9  can be done remotely/by telephone/telemedicine/in-home visits under exceptional circumstances due to the COVID-19 pandemic.
16
Shipment/dispensing/administration of study medication to/at the patient’s home is allowed for Visits 3, 4A, 6, 7 under exceptional circumstances due to the COVID-19 pandemic and
requires discussion with the sponsor first using a sponsor-approved shipment provider. Prior to shipment of study medication to the patient’s home, the investigator should first conduct a 
remote/telephone/telemedicine/in-home visit to discuss adverse events, concomitant therapies, glucose/ketone monitoring, and study medication compliance. The review of local 
laboratory results can occur after shipment of study medication but within the protocol defined window of the visit. Reasons for shipment of study medication to a patient’s home may 
include unwillingness to return to the investigator site due to concerns of COVID-19 exposure or suspected COVID-19 infection.
(*)
All patients’ legal representative(s) must sign an informed consent consistent with ICH-GCP guidelines prior to participation in the trial. Re-consenting may become necessary when 
new relevant information becomes available and should be conducted according to the sponsor’s instructions. Re-consent can be done remotely/by telephone/telemedicine/in-home 
visit under exceptional circumstances due to the COVID-19 pandemic. The initial informed consent and assent at Visit 1A must be done in the clinic.
(**)
Day of Randomisation / Day of first intake of randomised medication.
(***)
Completion of patient participation also needs to be completed if the patient withdraws prematurely following randomisation (see Section 3.3.4).

INTRODUCTION
1.1
MEDICAL BACKGROUND
Diabetes is an in prevalence increasing disease with an estimated 415 million affected people 
worldwide. In high-income countries, up to 91% of adults with the disease have type 2 
diabetes mellitus (T2DM) [R16-4703]. Complications associated with chronic
hyperglycaemia are currently one of the most frequent causes of adult-onset loss of vision, 
renal failure, and amputation in the industrialized world. Type 2 diabetes mellitus is 
associated with macrovascular complications with a 2- to 4-fold increase in cardiovascular 
disease risk. The high frequency of complications leads to a significant reduction of life 
expectancy.
T2DM in children and adolescents (youth-onset T2DM) has also become an increasingly 
important public health concern throughout the world with unique characteristics and 
demographics in many countries. Youth-onset T2DM occurs most often during the second 
decade of life and coincides with the peak of physiologic pubertal insulin resistance. T2DM
in children and adolescents occurs in all races but at a much greater prevalence in those of 
non-White European descent, e.g. those of Black African descent, native North American, 
Hispanic (especially Mexican)-American, Asian, South Asian, and Native Pacific islanders. 
In the USA and Europe, nearly all youth with T2DM have a body mass index (BMI) above 
the 85th percentile for age and sex. [P15-01571]. In the USA and Europe, youth-onset T2DM
is predominately found in populations characterised by low socioeconomic and educational 
status whereas in emerging countries like China and India, more affluent children are more 
likely to develop T2DM than poorer children [P15-01571].
Prevention and reversal of disease progression with diet and exercise is presently the 
preferred therapeutic approach but is rarely sufficient. Only 10% of children and adolescents 
with T2DM achieve glycaemic goals through diet and exercise alone. Although several 
antidiabetic compounds have been developed to improve glucose control in adults, metformin 
is the only oral agent recommended and approved as the initial pharmacologic treatment for 
T2DM in youth [P12-09397]. However, metformin is not suitable for all patients, as 
insufficient efficacy over time has been observed in several paediatric studies [R07-4400; 
R10-0796]. Insulin can also be used to lower plasma glucose levels but is often unacceptable 
to patients in the paediatric population due to the injectable route of delivery and the higher 
rates of hypoglycaemia and weight gain. Therefore there is a medical need for new 
antidiabetic drugs for children and adolescents for whom lifestyle change is not sufficient.
Empagliflozin is a reversible, highly potent (IC50 1.3 nM) and selective competitive inhibitor 
of sodium-glucose co-transporter 2 (SGLT-2), a member of a larger group of sodium 
substrate co-transporters, the sodium-glucose co-transport 5 (SLC5) gene family [R05-0939].
Under normoglycaemia, glucose is completely reabsorbed by SGLTs in the kidney, whereas 
the reuptake capacity of the kidney is saturated at plasma glucose concentrations higher than 
approximately 10-11 mmol/L, resulting in glycosuria. This threshold concentration can be 
decreased by SGLT-2 inhibition [c01678844-17]; an approximately 5000-fold selectivity 
over human SGLT-1 (IC50 6278 nM), responsible for glucose absorption in the gut, was 
calculated for empagliflozin [U06-1742].

Linagliptin is a potent inhibitor of DPP-4 activity and prolongs the half-life of GLP-1. This 
has been shown in vitro, in various animal models, and in clinical trials [c018916941-04].
Both compounds are approved for use as adjunct to diet and exercise as monotherapy and 
combined with other antidiabetic drugs including insulin. Empagliflozin and linagliptin are 
expected to show efficacy in terms of glucose control when used alone, as adjunct to diet and 
exercise and in combination with metformin and/or insulin in children and adolescents with 
T2DM.

DRUG PROFILE
1.2.1
Empagliflozin
Empagliflozin is an orally available, potent, and selective inhibitor of the SGLT-2. Its 
selective inhibition reduces renal reabsorption of glucose and promotes increased urinary
glucose excretion (UGE) resulting in reduction of blood glucose levels.
Empagliflozin for the treatment of T2DM is approved in over 100 countries including the 
European Union and the USA where it is marketed under the brand name Jardiance®.
Non-clinical assessment of safety
Empagliflozin has been extensively tested as part of the adult T2DM program as described in 
the Investigator’s Brochure [c01678844-17].
Clinical pharmacokinetics (PK), pharmacodynamics and safety in children and adolescents
The primary objective of the paediatric empagliflozin trial 1245.87 [c09087100] was to 
assess the pharmacokinetics of a single dose of empagliflozin (5 mg, 10 mg, and 25 mg) in 
paediatric patients with T2DM. The secondary objective of this study was to investigate the 
pharmacodynamics of a single dose of empagliflozin in the same population. 
Twenty seven patients with T2DM who were in the age range of 10 to less than 18 years and 
who had insufficient glycaemic control despite treatment with diet and exercise and/or stable 
metformin and/or stable basal or multiple dose injection (MDI) insulin therapy were
randomised and treated in this paediatric PK single dose trial. Following single dose 
administration of 5 mg or 10 mg or 25 mg, empagliflozin was rapidly absorbed in paediatric 
patients with T2DM with median values ranging from 1.25 h to 1.78 h. Empagliflozin 
exposure (both with respect to AUC and Cmax) increased with increasing dose. Mean terminal 
half-life (t1/2) was 7 to 8 h for all dose groups. The pharmacokinetic parameters of 10 mg and 
25 mg empagliflozin in paediatric patients with T2DM were compared with the results from a 
previous trial in adults [U09-1970] and with the results from population pharmacokinetic 
modelling in adult patients with T2DM [c02090424]. The pharmacokinetic exposure was 
generally comparable between paediatric and adult patients with T2DM, with a slightly lower 
exposure (with respect to AUC and Cmax) in paediatric patients in the 10 mg dose group 
compared with the adult patients. For the 2 doses (10 mg and 25 mg), median tmax and mean 
t1/2 were similar in adult and paediatric populations. The slightly lower exposure of paediatric

patients in the 10 mg dose group compared with adult patients may be related to the higher 
body weight of the paediatric population [c09087100].
In the paediatric patients included in this trial, a dose-dependent increase of UGE in the 24 h 
following empagliflozin administration was observed, with mean (standard error (SE)) 
changes from baseline (adjusted for baseline UGE and baseline FPG) of 53.1 (10.2) g/24 h in 
the 5 mg dose group, 73.0 (10.1) g/24 h in the 10 mg dose group, and 87.4 (9.4) g/24 h in the 
25 mg dose group. The effect on UGE in paediatric patients was comparable with the 
increase seen in a previous trial with adult patients with T2DM [U09-1970].
An exposure-response model, linking AUC0-24 to UGE at baseline and to UGE during the first 
24 h following empagliflozin administration (UGE0-24,1), was developed based on data from 3 
clinical trials in adult patients with T2DM [U09-1271; U09-1970; U10-2326] and the data 
from the 1245.87 trial with paediatric patients. After accounting for all significant covariates, 
adult and paediatric patients with T2DM had similar exposure-response relationships, 
following a single oral dose of empagliflozin.
All 3 single doses of empagliflozin were well tolerated in the 1245.87 trial. No new safety 
signals were observed. The safety results of this trial were consistent with those observed in 
previous empagliflozin trials in adults [c01678844-17].
Clinical efficacy and safety in adults
Empagliflozin has been studied as part of a global development program with more than 
20000 patients with T2DM treated in clinical studies of which more than 13000 were treated 
with empagliflozin, either alone or in combination with metformin, a sulphonylurea, a 
PPARγ agonist, dipeptidyl peptidase-4 inhibitors, or insulin.
The Phase III studies in T2DM showed that treatment with empagliflozin 10 mg or 25 mg 
once daily for up to 24 weeks results in a reduction of HbA1c up to 0.85%, body weight up to 
2.2 kg and systolic blood pressure (SBP) up to 4.8 mmHg compared with placebo. This was 
consistently observed with empagliflozin as monotherapy, add on to metformin, to the 
combination of metformin and sulphonylurea, to pioglitazone with or without metformin, and
to basal insulin with metformin and/or sulphonylurea. One Phase III study up to 204 weeks in 
T2DM supports the sustained effect of empagliflozin.
In clinical studies, empagliflozin was well tolerated in both healthy volunteers and patients 
with T2DM up to maximal treatment duration of 208 weeks in completed studies. The 
frequency of overall adverse events (AEs), AEs leading to discontinuation and serious AE 
(SAEs) were comparable to that with placebo. There was no significant increase in frequency 
of hypoglycaemia with empagliflozin compared to placebo except when used in combination 
with a sulphonylurea or basal insulin. There was an increase in frequency of genital 
infections with the use of empagliflozin. Empagliflozin treatment also increased urination and 
thirst. There was a small increase in total cholesterol, low-density lipoprotein (LDL) 
cholesterol and high-density lipoprotein (HDL) cholesterol and no significant changes of 
LDL/HDL cholesterol ratio and in triglycerides. In addition, increases in haematocrit, 
haemoglobin and red blood cell were observed with empagliflozin.  No clinically relevant 
changes in electrolytes were observed with empagliflozin.

The safety profile of empagliflozin in patients with renal impairment and decreased eGFR 
down to 15 mL/min/1.73m2 was consistent with that reported in patients with normal renal 
function; there is no experience in patients with endstage renal disease and in patients on 
dialysis. In the EMPA-REG OUTCOME® study, the overall safety profile of empagliflozin 
was comparable to the known safety profile of this agent.
In a phase III randomised, double-blind cardiovascular outcome trial (the EMPA-REG 
OUTCOME® study [c01678844-17]), empagliflozin was shown to be superior in reducing 
the primary endpoint 3 point Major Adverse Cardiac Events (MACE), a composite of 
cardiovascular death, non-fatal myocardial infarction (MI), or non-fatal stroke compared to 
placebo on top of standard of care in patient with T2DM and established cardiovascular 
disease. Empagliflozin treatment showed a nominally significant reduction in cardiovascular 
death with no significant change in non-fatal MI or non-fatal stroke. An improved overall 
survival driven by a reduction in cardiovascular death was also observed. Empagliflozin 
reduced the risk of hospitalization for heart failure and the composite of cardiovascular death 
or hospitalization for heart failure compared with placebo. The risk of new or worsening 
nephropathy (including onset of macroalbuminuria, doubling of serum creatinine and 
initiation of renal replacement therapy (i.e. haemodialysis)) was reduced in empagliflozin 
group compared to placebo. Empagliflozin showed a higher occurrence of sustained normo-
or microalbuminuria in patients with baseline macroalbuminuria compared with placebo. 
After an initial drop in eGFR, treatment with empagliflozin slowed progression of renal 
disease and eGFR returned to baseline 4 weeks after drug discontinuation while the placebo 
group showed a gradual decline in eGFR during the course of the study with no further 
change during the 4-week follow-up.

Linagliptin
Linagliptin is a potent inhibitor of DPP-4 activity and prolongs the half-life of GLP-1. This
has been shown in vitro, in various animal models, and in clinical trials. Linagliptin is an
orally available compound with a low risk for hypoglycaemic episodes [c018916941-04].
Linagliptin for the treatment of T2DM is approved in over 90 countries including the 
European Union (Trajenta®), the USA (Tradjenta®), and Japan (Trazenta®).
Non-clinical assessment of safety
Linagliptin has been extensively tested as part of the adult T2DM program as described in the

Clinical pharmacokinetics, pharmacodynamics, efficacy and safety in children and 
adolescents
The primary objective of trial 1218.56 [c09060697] was to identify the appropriate dose of 
linagliptin in paediatric patients with T2DM. Two doses of linagliptin (1 mg and 5 mg) were 
compared with placebo. A protocol-defined interim analysis was performed, which showed 
superiority of the linagliptin 5 mg dose over the linagliptin 1 mg dose regarding DPP-4 
inhibition at trough at steady state and a plasma DPP-4 inhibition by linagliptin 1 mg of less

than 80%. These results demonstrated inferior DPP-4 inhibition of linagliptin 1 mg and 
allowed early termination of the trial.
Thirty-eight treated patients between 10 and 17 years were randomised and included in the 
interim analysis. At final database lock (DBL), 39 patients had been randomised to and 
treated with placebo (15 patients), linagliptin 1 mg (10 patients) or linagliptin 5 mg (14 
patients). Patients had a documented diagnosis of T2DM obtained at least 3 months prior to 
randomisation and had insufficient glycaemic control despite treatment with diet and exercise 
and/or metformin with or without concomitant stable basal insulin therapy. 
The primary endpoint of the final analysis was the change from baseline in HbA1c (%) after 
12 weeks of treatment. Because of the early termination of the study, the trial had limited 
statistical power. After 12 weeks of treatment, the adjusted mean treatment difference 
between linagliptin 5 mg and placebo was −0.63 (95% CI: −1.50, 0.23; p = 0.1447). The 
adjusted mean treatment difference between linagliptin 1 mg and placebo was −0.48 (95% 
CI: −1.47, 0.51; p = 0.3295). As expected because of the limited power of the trial, a 
statistically significant difference to placebo could be demonstrated neither for the linagliptin 
1 mg dose nor for the linagliptin 5 mg dose. The reduction of −0.63 with linagliptin 5 mg is 
considered clinically meaningful. The results were in accordance with data from adult 
patients after 12 weeks of treatment with linagliptin 5 mg. The median change from baseline 
in HbA1c (%) was +0.50 in the placebo group, -0.05 in the linagliptin 1 mg group, and -0.30 
in the linagliptin 5 mg group. The difference to placebo was -0.80 in the linagliptin 5 mg 
group compared with -0.55 in the linagliptin 1 mg group. The results were consistent with 
data from adult patients after 12 weeks of treatment with linagliptin 5 mg. In the linagliptin 5 
mg group, a reduction in HbA1c compared with baseline was seen over the entire randomised 
treatment period. In contrast, HbA1c had returned almost to baseline in the linagliptin 1 mg 
group and had increased beyond baseline HbA1c in the placebo group at Week 12. The 
percentage of patients with a relative efficacy response (HbA1c lowering by at least 0.5%) 
was greater in the linagliptin 5 mg group (30.8%) than in the linagliptin 1 mg group (20.0%) 
or placebo group (14.3%). Furthermore, the proportion of patients who had a baseline HbA1c 
≥7% and reached target HbA1c <7% (absolute efficacy response) was greater with linagliptin 
5 mg (36.4%) than with placebo (18.2%), whereas it was 10.0% with linagliptin 1 mg. A 
target HbA1c <7% is more difficult to achieve for patients with a higher baseline HbA1c 
value than for patients with a lower baseline HbA1c value.
For this trial, DPP-4 inhibition was defined as key secondary endpoint. Baseline DPP-4 
activity was similar across treatment groups. DPP-4 inhibition at trough at steady-state was 
clearly more pronounced for the linagliptin 5 mg dose group than for the 1 mg dose group, 
with median values of 79% and 38%, respectively. Median DPP-4 inhibition by linagliptin 5 
mg in the paediatric patients of trial 1218.56 was similar to the median DPP-4 inhibition 
obtained with linagliptin 5 mg in adults after 12 weeks of treatment (study 1218.6 [U08-
1056]: 85.0%; study 1218.5 [U08-3761]: 82.5%).
Fasting plasma glucose (FPG) was analysed as secondary endpoint. The placebo-corrected
adjusted mean change from baseline in the linagliptin 5 mg group was −34.2 mg/dL (95% CI: 
−77.7, 9.3; p = 0.1189). The placebo-corrected adjusted mean change from baseline in the 
linagliptin 1 mg group was considerably lower with −5.6 mg/dL (95% CI: −55.5, 44.4; p =

0.8216). The reduction in FPG with linagliptin 5 mg was similar to that in adult patients 
treated with linagliptin 5 mg. The median change from baseline in FPG was +19.5 mg/dL 
with placebo, +29.5 mg/dL with linagliptin 1 mg, and -5.0 mg/dL with linagliptin 5 mg. The 
placebo-corrected median FPG change from baseline at Week 12 was -24.5 mg/dL in the 
linagliptin 5 mg group and +10.0 mg/dL in the linagliptin 1 mg group. The placebo-corrected 
median FPG change from baseline of -24.5 mg/dL with linagliptin 5 mg is considered 
clinically meaningful and was comparable with that in adults receiving linagliptin 5 mg over 
12 weeks [U08-1056].
Systemic exposure was assessed based on linagliptin plasma levels. Linagliptin trough levels
in the 5 mg dose group were higher than in the 1 mg dose group, with geometric mean 
(gMean) values of 7.42 and 3.80 nmol/L, respectively.
Linagliptin was well tolerated. No new safety signals were detected in paediatric patients who
received linagliptin. The safety profile of linagliptin in paediatric patients was consistent with
that in adults [c018916941-04].
Clinical efficacy and safety in adults
Treatment with linagliptin 5 mg q.d. has resulted in clinically meaningful and statistically 
significant reductions in HbA1c, FPG, and postprandial glucose. There is a consistent pattern 
in the improvement in HbA1c levels when linagliptin was used in patients with different 
background therapies. These findings demonstrate efficacy for up to 18 to 24 weeks duration 
for different background therapies and are further supported by trials of longer duration up to 
104 weeks.
The treatment difference to placebo in the HbA1c change from baseline after 24 weeks of 
treatment was -0.69% (95% CI: -0.85, -0.32) for linagliptin 5 mg monotherapy (trial 
1218.16), -0.64% (95% CI: -0.78, -0.50) for linagliptin 5 mg with metformin background
therapy (trial 1218.17) and -0.65% (95% CI: -0.74, -0.55) for linagliptin 5 mg with basal 
insulin background therapy (trial 1218.36) [c018916941-04].
In the phase III studies the overall incidence of AEs, drug related AEs, AEs of severe
intensity, AEs leading to discontinuation, and serious adverse events (SAEs) were very
similar across studies, with linagliptin being mostly comparable to placebo. 
For monotherapy with linagliptin, nasopharyngitis, cough, hypersensitivity, lipase increase
and pancreatitis have been identified as adverse drug reactions. In addition, based on post-
marketing data, angioedema, urticaria, rash, mouth ulceration and bullous pemphigoid, are 
other ADRs listed for linagliptin.
Studies in patients on metformin background showed that the percentages of patients with 
adverse events were comparable between treatments (54.3% placebo plus metformin, 49.0% 
linagliptin 5 mg plus metformin). The number of patients with SAEs was low in both 
treatment groups (2.5% placebo plus metformin, 3.0% linagliptin 5 mg plus metformin).
The combination of linagliptin and insulin has been tested in clinical trials in different 
populations. Studies in patients on insulin background (with or without other oral antidiabetic 
drugs) had the highest reported frequency of investigator reported hypoglycaemic adverse 
events in both treatment arms, with comparable rates between the placebo group and

linagliptin. Overall, it has been shown that linagliptin is an effective and safe add-on therapy 
to insulin in patients with T2DM. This combination therapy was also shown to be safe and 
effective in vulnerable, elderly T2DM patients and in T2DM patients with renal impairment 
[P13-14398, c018916941-04].
The growing safety evidence base for linagliptin, including completed Phase III and IV 
clinical trials, comprises patients treated with background therapies of metformin, 
sulphonylurea, empagliflozin, and insulin. To date, in Phase III trials in patients with T2DM, 
linagliptin elicited meaningful glucose-lowering effects and was well tolerated with little 
intrinsic risk for hypoglycaemia [P10-14001, P11-02847, P11-06845, P11-09378, P11-12477, 
c018916941-04].
In summary, linagliptin has been shown to be effective and safe as an add-on therapy that can 
help patients on basal insulin to improve their blood sugar control without weight gain or 
additional risk of hypoglycaemia.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
Empagliflozin (10 mg and 25 mg) and linagliptin (5 mg) are approved for the treatment of 
adult patients with T2DM.
The paediatric T2DM prevalence is growing and positively correlated with obesity. 
Prevention and reversal of disease progression with diet and exercise is presently the 
preferred initial therapy when hyperglycaemia is not considered as severe. However, lifestyle 
modifications are difficult to implement and require intensive follow-up to be effective. 
Overall, less than 10% of paediatric patients diagnosed with T2DM can achieve glycaemic 
targets (HbA1c < 7.0% and FPG < 126 mg/dl) by following lifestyle interventions alone 
[R07-4402]. As a result, pharmacotherapy is often required and although there are many 
agents available to improve the metabolic abnormalities, there are little data concerning their 
use in children and adolescents.
Based on the results from two dose-finding studies in paediatric patients with T2DM with 
each of the compounds [c09087100 ; c09060697], this phase III trial is planned to confirm 
the efficacy and safety of empagliflozin and linagliptin in children and adolescents with 
T2DM.
There is a medical need for new antidiabetic drugs for children and adolescents for whom 
lifestyle change is not sufficient and as add-on to metformin and/or insulin therapy. In 
addition, this trial is being conducted to satisfy both the empagliflozin and linagliptin 
Paediatric Investigation Plans (PIPs) approved by the European Medicines Agency as well as 
the Post-Marketing Requirements (PMRs) agreed with FDA.
Rationale for background therapies
The trial is planned to be conducted in children and adolescents treated with diet and exercise 
and metformin and/or insulin background, reflecting the current standard of care. Patients not 
tolerating metformin (as defined in Section 3.3.2) and treated with diet and exercise only will 
also be eligible. This subgroup of pediatric patients has a high unmet medical need for oral 
antidiabetic drugs beside metformin and is expected to highly benefit from inclusion into this 
trial. Recent data from the Pediatric Diabetes Consortium (PDC) showed that 35% of children 
and adolescents with T2DM were treated with metformin alone, 19% with insulin alone, 31% 
with both metformin and insulin, 13% with lifestyle modification alone, and only 3% were 
treated with other glucose-lowering medications with/without metformin or insulin. Overall, 
51% of included patients were on insulin therapy [R16-2240].
Metformin is approved and largely used in youth but insufficient efficacy in terms of durable 
glycaemic control has been confirmed in a recent paediatric study [R07-4397]. Moreover, 
metformin is not suitable for all patients, as insufficient efficacy over time has been observed 
in several paediatric studies [R07-4400; R10-0796]. The alternative option for paediatric 
patients is the administration of insulin by injection as the only other approved medication for

treating their T2DM. Insulin is often unacceptable in the paediatric population due to the 
subcutaneous route of delivery and the higher rates of hypoglycaemia and weight gain.
DINAMOTM Mono
The TODAY study has shown that the majority of youth with T2D can be effectively treated 
with metformin monotherapy during the first 12 months of the disease [R12-3961]. However, 
the TODAY study also demonstrated that metformin monotherapy fails to maintain HbA1c <
8.0% in most adolescents during the second year of treatment [R18-2686], even in the face of 
substantial residual endogenous insulin [R18-2687]. Therefore, studies are warranted to 
assess whether oral antidiabetic medications can either replace metformin as initial therapy or 
whether a patients can switch from metformin monotherapy in case of metformin failure to 
another oral antidiabetic medication instead of initiation of insulin therapy. 
Therefore, in order to assess the efficacy and safety of empagliflozin and linagliptin as 
monotherapy, the ancillary study DINAMOTM Mono will be conducted in children and 
adolescents who are drug-naïve patients or patients not on active treatment (including 
discontinuation of metformin due to intolerance [or previous discontinuation for other 
reasons] and/or discontinuation of insulin [insulin use must be 8 weeks or less] at 
investigator’s discretion) prior to or at Visit 1A.
2.2
TRIAL OBJECTIVES
DINAMOTM (main study)
The objective of this study is to assess the efficacy and safety of an empagliflozin dosing 
regimen and one dose of linagliptin versus placebo after 26 weeks of treatment in children 
and adolescents with type 2 diabetes mellitus treated with metformin and/or insulin or who 
are not tolerating metformin.
DINAMOTM Mono (ancillary study)
The objective of this study is to explore the effect of an empagliflozin dosing regimen and 
one dose of linagliptin as Monotherapy in children and adolescents with type 2 diabetes 
mellitus.
In addition, the trial will assess the long term safety of empagliflozin and linagliptin after 52 
weeks of treatment.
2.3
BENEFIT - RISK ASSESSMENT
The clinical development programs in adults showed a favourable benefit-risk ratio for the 
use of linagliptin and empagliflozin in patients with T2DM. Besides, the linagliptin paediatric 
dose-finding trial as well as the empagliflozin paediatric PK single dose trial allowed 
identifying the appropriate dose(s) of each compounds for the paediatric population. Since
the paediatric population is considered as a vulnerable population, this combined phase III 
trial was therefore designed to conduct one confirmatory trial to assess efficacy and the long 
term safety of empagliflozin and linagliptin in children and adolescents with T2DM.

According to the drug assignment planned in this trial, 67% of the patients will be treated 
with either linagliptin or empagliflozin up to 52 weeks. These patients might benefit from 
positive glycaemic effects since they will receive an investigational medication that has 
already demonstrated favourable HbA1c and fasting plasma glucose changes in adults. 
Patients initially randomised to placebo treatment will continue treatment with diet and 
exercise alone or with metformin and/or insulin, reflecting the current standard of care. Due 
to the study procedures, such as regular visits, it is expected that patients will also benefit 
during the placebo treatment phase. In case of deterioration of glycaemic control, criteria for 
initiation of rescue therapy are in place (see Section 4.2.1). However, after 26 weeks of 
treatment, patients who were initially randomised to placebo will be re-randomised to either 
linagliptin 5 mg or empagliflozin 10 mg or 25 mg, to ensure a minimum of 26 weeks active 
treatment for all patients included into this trial. 
Patients in the placebo group may have a higher probability of treatment failure, i.e. of 
increased FPG and HbA1c values. However, the trial eligibility criteria (see Section 3.3.2 and 
Section 3.3.3) will ensure that unstable patients in terms of glycaemic control are excluded 
from being randomised. Following randomisation, appropriate criteria (based on HbA1c and 
blood ketone levels) have been defined for the initiation of rescue medication (please refer to 
Section 4.2.1 for further details). In addition, the patient safety will be monitored and a 
number of discontinuation criteria have been defined (see Section 3.3.4 for further details). 
The trial design with a two-week placebo run-in phase is a well-established design for T2DM
trials [P10-14001]. In this trial, daily monitoring of blood glucose will be performed by 
patients with a self-blood glucose monitoring (SBGM) device. Thus the risk of the two-week 
placebo treatment will be minimal.
Blood volumes drawn for safety analysis and efficacy endpoints analysis have been reduced 
since this trial is conducted in the paediatric population. Furthermore, to minimise pain and 
distress, local anaesthetic product will be offered to all patients as pain relief for 
venepuncture. Attempts to draw blood will be limited to three. Children with needle phobia 
will be excluded from the study.
Due to the mechanism of action of empagliflozin and linagliptin, the risk of hypoglycaemic 
episodes is considered to be very low. Add-on of empagliflozin and linagliptin to a stable 
dose of insulin/metformin therapy is deemed acceptable as there are no relevant drug-drug 
interactions and no potentiated effects are expected. In a study of adult patients receiving 
linagliptin as add-on therapy to a stable dose of insulin, no significant difference was 
observed in the incidence of hypoglycaemia between the linagliptin and placebo treated 
groups. Hypoglycaemia was seen more frequently compared to placebo in adult patients 
treated with linagliptin on background of metformin+sulfonylurea. Also, the risk of severe 
hypoglycaemic episodes is considered to be low for empagliflozin (<1%) and similar for 
empagliflozin and placebo as monotherapy and as add-on to metformin. Compared to placebo 
when empagliflozin is given as add-on to insulin the number of major hypoglycaemic events 
may be increased.
However, in order to closely monitor hypoglycaemic events, all patients will be required to 
perform regular blood glucose measurements (self-blood glucose monitoring – SBGM)

throughout the duration of the trial. Minimum requirements have been defined in the protocol 
(See Section 5.3.5.2 for further details).
For linagliptin, pancreatitis is an important but uncommon risk. Other important known risks 
of linagliptin include hypersensitivity and angioedema/urticaria. 
Cases of diabetic ketoacidosis (DKA), a serious life-threatening condition requiring urgent 
hospitalization, have been reported in patients treated with SGLT-2 inhibitors, including 
empagliflozin. It needs to be taken into account that, due to the insulin independent mode of 
action, empagliflozin may potentially modify the clinical presentation of DKA. In some of 
reported cases, the presentation of the condition was atypical with only moderately increased 
blood glucose values, below 14 mmol/L (250 mg/dL). The risk of DKA must be considered 
in the event of non-specific symptoms such as nausea, vomiting, anorexia, abdominal pain, 
excessive thirst, difficulty in breathing, confusion, unusual fatigue or sleepiness. Patients 
should be assessed for ketoacidosis immediately if these symptoms occur, regardless of blood 
glucose level. In patients treated with empagliflozin consider monitoring for ketoacidosis and 
temporarily discontinuing empagliflozin in clinical situations known to predispose to 
ketoacidosis (i.e. prolonged fasting due to acute illness or surgery). In these situations, 
consider monitoring of ketones, even if empagliflozin treatment has been interrupted.
Patients receiving empagliflozin may be at risk to underestimate their need for insulin if 
blood sugar levels are within individual target ranges or only slightly elevated. Insulin 
deficiency might lead to ketoacidosis which could be life-threatening if not recognized and 
appropriately treated. All patients receiving insulin will be made aware of this risk and be 
instructed not to reduce their insulin dose below investigator recommendations. 
In addition to blood glucose monitoring, patients will be equipped with an electronic device 
to determine their ketone concentration (i.e. a blood glucose monitoring device/meter that is 
also capable of measuring blood ketones) (for further details see Section 5.3.5.3). Patients 
will be reminded how to determine ketones in case of any symptoms of DKA, e.g. nausea, 
vomiting, abdominal pain etc. They will be instructed to do this irrespective of the glucose 
value in the event of DKA symptoms occurring. More frequent ketone testing (e.g. once 
daily) will be recommended during the first 4 weeks of the treatment period and during 4 
weeks after Visit 5; this will allow patients and investigators to understand baseline ketosis 
rates and compare them, as appropriate, to the incidence of ketosis following the initiation of 
study medication. As stated above, a meter will be provided to the patient for this purpose; as 
an additional safeguard, the meter will also be used to check ketone levels at most clinic 
visits (see Flow Chart). Patients will be reminded of the interpretation of ketone values 
measured by the meter, and on appropriate action to be taken in the event of increased ketone 
levels (see Section 5.3.5.3). In addition, patients with insulin background therapy will be 
reminded about insulin adjustment during “sick days” and about the importance of keeping 
themselves hydrated.
Investigators should also differentiate deteriorating ketosis/DKA from any mild to moderate
increase of ketones which may be seen due to the mechanism of action of empagliflozin,
especially in the fasted state (e.g. in the morning).

Cases of necrotizing fasciitis of the perineum (Fournier’s gangrene), a rare, but serious and 
life-threatening necrotizing infection, have been reported in patients with diabetes mellitus 
treated with SGLT-2 inhibitors, including empagliflozin. Patients who present with 
suggestive symptoms are instructed to seek medical attention immediately and should be 
evaluated for necrotizing fasciitis. 
Patients will be carefully selected for the trial in line with the eligibility criteria, to ensure, in
the investigator’s judgment, that they have a good understanding of their disease and how to
manage it. They should also be selected in terms of their ability to be compliant with the
demands of the trial.
In the embryo-foetal and fertility studies in rats and rabbits, no effects on early embryonic 
development, mating, male and female fertility, and bearing live young were observed up to a 
linagliptin dose of 240 mg/kg and up to a dose of 300 mg/kg with empagliflozin. Therefore, 
female patients who have reached menarche (i.e. those who have had any vaginal bleeding, 
however scant or irregular) and are of child-bearing potential will be included in this study 
provided that they are using adequate contraceptive methods. In addition, regular pregnancy 
tests will be performed throughout their trial participation.
As with all drugs, the potential for hypersensitivity and allergic reactions have to be taken 
into consideration when empagliflozin or linagliptin is administered. Other risks to the 
patients are the risks inherent to any investigational medicinal product used in a clinical trial 
setting, such as unexpected adverse clinical or laboratory events. 
Hence, for sites taking part in this trial, the investigator and designated site personnel must be 
trained in paediatric emergencies. Patient discomfort will be minimised as far as possible, and 
all sites selected to take part in this trial will be knowledgeable and skilled in dealing with the 
paediatric population and its age-appropriate needs. Furthermore, sites will be assessed for a 
child-friendly infrastructure (e.g. familiar environment, appropriate physical setting, 
parent(s)/legal guardian allowed to accompany patient during procedures).
Individual patient safety/risks will be minimised by close observation throughout the trial, 
and by monitoring the patients for adverse events both clinically and by laboratory testing.
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure patients´ 
safety, see also Section 5.3.6.1.
To continue the assessment of the long-term safety of empagliflozin and linagliptin, an 
adjudication of cardiovascular, DKA and certain hepatic events will be performed. The 
progress of the trial will also be assessed at regular intervals by an independent Data 
Monitoring Committee (DMC). For further details please refer to Section 3.1.1.
Given the safety profile derived from toxicology studies, the good tolerability seen in 
previous studies in adult and paediatric patients and the monitoring activities including the 
blood glucose and ketone monitoring described above, the sponsor is of the opinion that the

risks for participating patients are minimised and justified when compared to the potential 
benefits of a successful development of empagliflozin and linagliptin for children and 
adolescents with T2DM.
COVID-19 Pandemic
Due to the COVID-19 pandemic, the enrollment of new patients and the initiation of new 
sites were temporarily put on hold on 17 March 2020 and resumed on a per country level in 
April 2020. Potential risks with regard to COVID-19 exposure and treatment for patients 
already enrolled in the trial have been evaluated and described in a specific Benefit-Risk 
assessment document [c32537051-02 ; c32537611-02].
Based on the pharmacological mechanism of empagliflozin and linagliptin and review of data 
derived from clinical and post-marketing databases, there is no indication that these 
investigational drugs could increase the risk of severe viral infections. Moreover, no relevant 
Drug-Drug Interactions between empagliflozin and linagliptin and the medications currently 
used for treatment of COVID-19 are expected based on the information in their product 
labels, nor have they been described in the literature. Please refer to the respective current 
Investigator Brochures (IB). 
As with any acute illness, a Severe Acute Respiratory Syndrome (SARS) CoV-2 infection 
may increase the risk of DKA. The risk of ketoacidosis in case of acute illness during 
empagliflozin intake is adequately addressed in the IB. Consistent with the guidance on 
illness-related treatment discontinuation, the study drug should be discontinued in case of 
severe COVID-19 disease and re-introduced once the patient has recovered, as described in 
Section 3.3.4.1.
Patients with diabetes are in general at higher risk of infections and might be at higher risk 
for severe illness from COVID-19. The majority of patients in the DINAMO trial are 
randomized to active treatment due to the trial design and would, therefore, be expected to be 
in a better blood glucose control. Nevertheless, in order to minimize the risk of exposure to 
COVID-19, physical visits should be avoided depending on the COVID-19 pandemic status 
of the site. The use of phone visits and local laboratory services for safety and efficacy 
parameters measurements should be considered when necessary. Furthermore, study drug 
shipment to patient’s homes should also be considered. Investigators should complete study 
procedures according to the protocol to the extent possible. If protocol-mandated visits, safety 
laboratory schedules, and/or study drug availability cannot be accomplished, patients should 
temporarily discontinue study medication.
Based on the above considerations, the Benefit-Risk assessment for trial participants remains 
positive.

increasing the dose of empagliflozin is beneficial to paediatric patients with T2DM. Since 
patients and investigators will stay blinded, investigators will have to perform an IRT call for 
all patients at Week 14 in order to get new trial medication kits assigned (see Section 4.1.4
for further details). The re-randomisation will be stratified by age at baseline (< 15 years; ≥ 
15 and < 18 years) as described in Section 7.6.
Re-randomisation at Week 26
After the 26-week treatment period, all patients will enter a double-blind safety extension 
period up to 52 weeks. Patients who received placebo during the 26-week treatment period 
will be re-randomised to receive either linagliptin 5 mg or empagliflozin 10 mg or 
empagliflozin 25 mg. Since patients and investigators will stay blinded, investigators will 
have to perform an IRT call for all patients at Week 26 in order to get new trial medication 
kits assigned (see Section 4.1.4 for further details). The re-randomisation will be stratified by 
age at baseline (< 15 years; ≥ 15 and < 18 years) as described in Section 7.6.
After the 52-week extension period, all patients will enter a 3-week follow-up period during 
which they will not be treated with study medication. The patient’s participation is concluded 
when he has undergone the last planned visit (i.e. Trial Completion Visit); last-patient-last-
visit-primary-endpoint will occur when all patients have completed 26 weeks of treatment. 
The end of the trial is defined as “last patient out” (i.e. last Trial Completion Visit completed 
by the last patient in the trial). 
Except for patients who would discontinue the trial treatment for safety reasons, every effort 
should be made to re-introduce trial treatment after a temporary trial drug discontinuation. 
For the analysis of this trial it is very important that assessments for each planned visit are 
still performed in accordance with the Flow Chart even if patients discontinue trial treatment.
Patients who discontinue study drug prematurely should continue study visits until study end. 
Study assessments may be omitted if a patient is willing to return to the pre-defined study 
visits, with exception of blood drawing for safety lab tests, HbA1c and FPG, body weight, 
blood pressure and collection of adverse events and concomitant therapy. Refer to Section 
6.2.3 for premature discontinuation of treatment guidance.
Every attempt will be made by the investigator to ensure patients continue participating in the 
study during interruptions in trial drug intake and after permanent discontinuation of trial 
drug. The modified Intention-to-Treat (mITT) analysis requires that all trial patients be 
followed until study end even if the trial drug was temporarily interrupted or discontinued.

(including myocardial infarction), cardiovascular death and other relevant events (e.g. 
hospitalisation for heart failure) based on the FDA guideline [R09-2151]. Such adjudication 
is performed in all Phase 2 and 3 clinical trials with empagliflozin and linagliptin. The CEC 
will evaluate whether pre-specified criteria for adjudication endpoints are met.
For any events that qualify for adjudication, study sites will be asked to provide clinical 
documentation such as electrocardiograms (ECGs), laboratory values, angiography, 
echocardiography reports, CT and/or MRI scans, discharge summaries, and autopsy reports to 
support the external event adjudication.

DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP(S)
This trial will investigate the efficacy and safety of an empagliflozin dosing regimen and one 
dose of linagliptin on top of standard treatment in children and adolescents with T2DM.
HbA1c as the primary endpoint has been demonstrated to be a reflection of the glycaemic 
control over the preceding 12 weeks and maintenance data over a period of approximately 6 
months are requested by the different regulatory agencies. Therefore the primary endpoint for 
DINAMOTM is the change in HbA1c from baseline to the end of 26 weeks of randomised 
treatment. 
For DINAMOTM Mono, the endpoint “occurrence of treatment failure” is selected to evaluate 
whether an early initial monotherapy is beneficial in children and adolescents with T2DM. A 
major component of the endpoint is “use of rescue medication”. Virtually all patients in 
DINAMOTM Mono who will not achieve the glycemic goals defined in guidelines will

require rescue medication and will be classified as failure. Therefore, the study will inform 
whether the initial monotherapy can bring patients to glycemic target. Comparison with a 
placebo group is needed to better understand the failure rate of an “untreated population” in 
order to bring the results for empagliflozin and linagliptin into perspective. A similar 
endpoint was used in the TODAY study [R12-3961]. Since strict rescue criteria are defined 
for DINAMOTM Mono, the commonly used endpoint “HbA1c change from baseline” would 
not be informative. In the placebo group a high rate of rescue medication is expected, i.e. 
most patients randomised to placebo will benefit from metformin or insulin therapy. Since 
metformin and insulin are very effective especially in newly diagnosed patients, it  is 
expected to observe no difference in HbA1c after 26 weeks in patients randomised to 
empagliflozin or linagliptin and placebo (on rescue treatment).
The randomised period is planned for 52 weeks in order to collect one year safety and 
efficacy data for empagliflozin and linagliptin in patients with T2DM aged 10-17 years
(inclusive).
For the linagliptin treatment arm, one dose (i.e. linagliptin 5 mg) will be evaluated for safety 
over 52 weeks. For empagliflozin, two doses (i.e. empagliflozin 10 mg and 25 mg) will be 
evaluated as well as whether increasing the dose of empagliflozin 10 mg to 25 mg is 
beneficial to paediatric patients. So that, patients initially randomised to the empagliflozin 10 
mg group who will not achieve an HbA1c target < 7.0% at Week 12 will be re-randomised at 
Week 14 to receive either empagliflozin 10 mg or empagliflozin 25 mg. 
The rationale for the empagliflozin and linagliptin dose selection is described in section 4.1.2.
Patients who were randomised to placebo will be re-randomised after 26 weeks to either 
linagliptin 5 mg or empagliflozin 10 mg or empagliflozin 25 mg. This reduces the duration of 
the placebo period in this trial to the requested minimum (26 weeks) and will ensure that all 
patients will receive active treatment for at least 26 weeks. Moreover, this will generate 
additional safety and efficacy data over 26 weeks of treatment for both empagliflozin doses 
and one linagliptin dose.
The design of this trial includes a 2-week open-label placebo run-in period; the intention of 
this period is to familiarise the patient with the procedures for study medication intake prior 
to randomisation, giving an opportunity for assessing the patient ability to be compliant with 
the study medication intake. This is of particular importance within the paediatric population 
where adherence to medical regimens is often less than desired. The run-in period will 
therefore ensure that only patients who are likely to be compliant are exposed to the study 
drugs.
The 3-week follow-up period is considered to be sufficient, as previous studies with 
empagliflozin and linagliptin have shown that its’ PD effect only extends to about 3 and 7
days after the last dose. Furthermore, it will allow for the assessment of reversibility of 
unexpected long-term side effects.

SELECTION OF TRIAL POPULATION
A sufficient number of patients with T2DM will be screened to ensure the randomisation of 
at least 150 and approximately 20 patients from approximately 110 trial sites in DINAMOTM
and DINAMOTM Mono respectively. The planned number of patients randomized at each site 
is at least one patient in DINAMOTM and at least one patient in those sites that participate in 
DINAMOTM Mono.
If enrolment is delayed, additional sites may be recruited. 
At least 30% and not more than 70% of patients should be below 15 year of age. In addition
for DINAMOTM only, between 30% and 70% of randomised patients must be girls.
Screening of patients for this trial is competitive across all countries within the trial, i.e. 
screening for the trial will stop at all sites when the desired number of patients to be 
randomised in this trial is reached. Investigators will be notified when sufficient patients have 
been randomised and when screening is complete and will not be allowed to recruit additional 
patients for the study. Patients who have completed Visit 1A procedures prior to notification 
of the termination of recruitment will be allowed to continue in the study if they meet all 
entry criteria and they are able to follow the visit schedule in this Clinical Trial Protocol.
Re-screening and/or re-testing (of assessments) are permitted.
Whilst the information provided below is not an exhaustive list, it provides some guidance as 
to when such re-screening and/or re-testing would be considered appropriate.
Re-testing:
Re-testing for eligibility criteria is only to be performed for a laboratory test that has been 
cancelled by the central laboratory (e.g. for specimen not received or received beyond 
stability) or for a laboratory result thought to be a spurious result based on previously 
available laboratory results. The re-test should be carried out as soon as possible so the 
laboratory test results will be received within the next planned visit windows in order to 
avoid protocol window deviations.
Re-screening:
For patients failing screening due to modifiable exclusion criteria, like HbA1c level too low 
or too high, unrecognized hypothyroidism (high TSH), re-screening may be considered up to 
5 times with at least 8 weeks between screening visits.
The patient should be declared as a screening failure in the eCRF and IRT with their original 
patient number.
Upon re-screening, a new patient number will be assigned by the IRT. The old patient 
number, with which the patient failed screening, will be recorded in the eCRF.
The patients’ legal representative(s) must be re-consented using the current approved version 
of the information sheet and consent form. The patient should give again his/her assent.

Removal of patients from therapy or assessments
Patients may be withdrawn from trial treatment or from the trial as a whole (“withdrawal of 
consent”) with very different implications, please see sections 3.3.4.1 and 3.3.4.2 below.
Every effort should be made to keep the randomised patients in the trial, if possible on 
treatment or at least to collect important trial data.
Measures to control the withdrawal rate include but is not limited to careful patient selection, 
appropriate explanation of the trial requirements and procedures prior to randomisation, 
investigator’s training to clearly explain the consequences of consent withdrawal, regular 
oversight of retention rates by the SC and the sponsor-based clinical monitors, reimbursement 
of travel costs, offers for snack or breakfast during clinic visits, option for an ambulatory visit 
as detailed in the Flow Chart, telephone calls to the patient or the patient’s family. 
The decision to withdraw from trial treatment or to withdraw consent as well as the reason 
must be documented in the patient files and CRF.
3.3.4.1
Withdrawal from trial treatment
An individual patient is to be withdrawn from trial treatment if:
∀
The patient or parent(s) (or legal guardian) wants to withdraw from trial treatment, 
without the need to justify the decision.
∀
The patient needs to start a restricted concomitant therapy that, in the investigator’s 
opinion, poses a safety risk if taken as add-on to the trial medication (see section 
4.2.2.1).
∀
The patient can no longer be treated with trial medication for other medical reasons 
(such as surgery, adverse events, other diseases, or pregnancy).
∀
The patient has repeatedly shown to be non-compliant with important trial procedures 
and, in the opinion of both, the investigator and sponsor representative, is not willing 
or able to stick to the trial requirements in the future.
∀
Pancreatitis, bullous pemphigoid, ketoacidosis, arthralgia, or Fournier’s gangrene is 
suspected.
Given the patient’s agreement, the patient will undergo the procedures for early treatment 
discontinuation and all subsequent planned visits up to the follow up visit as outlined in 
section 6.2.3.

For all patients the reason for withdrawal from trial treatment (e.g. adverse events) must be 
recorded in the eCRF. These data will be included in the trial database and reported.
Except for patients who would discontinue the trial treatment for safety reasons, every effort 
should be made to re-introduce trial treatment after a temporary trial drug discontinuation. 
For the analysis of this trial it is very important that assessments for each planned visit are 
still performed in accordance with the Flow Chart even if patients discontinue trial treatment. 
Patients who discontinue treatment prematurely will be followed up until the end of the 
study, unless they withdraw their consent for this to happen. All assessments related to the 
primary and secondary endpoints (i.e., blood drawing for HbA1c and FPG, body weight, 
blood pressure and collection of adverse events and concomitant therapy) and safety lab tests 
still have to be performed as if the patient had remained on trial treatment.
Patients who withdraw from the trial treatment after randomisation will not be replaced.
However, one exception is patients who discontinue due to the COVID-19 pandemic (i.e. 
missed visits, SARS CoV-2 infection, withdrawal of consent) may be replaced based on 
blinded assessment of the number of premature treatment or trial discontinuation.
3.3.4.2
Withdrawal of consent for trial participation
Patients or parent(s) (or legal guardian) may withdraw their consent/assent for trial 
participation at any time without the need to justify the decision.
This will however mean that no further information may be collected for the purpose of the 
trial and negative implications for the scientific value may be the consequence. Furthermore 
it may mean that further patient follow-up on safety cannot occur.
If a patient or parent(s) (or legal guardian) wants to withdraw consent/assent, the investigator 
should explain the difference between treatment withdrawal and withdrawal of consent for 
trial participation and explain the scientific relevance of their data even if he/she discontinue 
the trial treatment.
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for the following reasons:
∀
Failure to meet expected enrolment goals overall or at a particular trial site
∀
Emergence of any efficacy/safety information invalidating the earlier positive 
benefit-risk assessment that could significantly affect the continuation of the trial
∀
Violation of GCP, the trial protocol, or the contract impairing the appropriate 
conduct of the trial
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).

4.1.2
Selection of doses in the trial
Empagliflozin will be administered as 10 mg and 25 mg tablets once daily, linagliptin as 5 
mg tablet once daily. These doses were selected based on the results from previous dose 
finding studies in paediatric patients with T2DM (see below) and are the same doses that are 
approved in adult patients with T2DM. 
Empagliflozin
The empagliflozin paediatric PK/PD trial 1245.87 [c09087100] showed that, following a 
single oral dose of empagliflozin, adult and paediatric patients with T2DM had similar 
exposure-response relationships after accounting for significant covariates. Therefore, the 
paediatric dose finding trial results support the use of empagliflozin 10 mg and 25 mg in this 
phase III trial (the same doses that are approved/used for adult patients with T2DM). See 
sections 1.2 and 3.2 for further details.
Linagliptin
The linagliptin paediatric dose finding trial 1218.56 [c09060697] interim analysis showed 
superiority of the linagliptin 5 mg dose over the linagliptin 1 mg dose regarding DPP-4 
inhibition at trough at steady state. Besides, the results were consistent with clinical efficacy 
and safety data for linagliptin in adults. As a consequence, the paediatric dose finding trial 
findings support the evaluation of the long-term safety and efficacy of linagliptin 5 mg in this 
phase III trial in children and adolescents (the same dose that is approved/used in adult 
patients with T2DM). See sections 1.2 and 3.2 for further details.
4.1.3
Method of assigning patients to treatment groups
During Visit 2, eligible patients will be randomised to receive either linagliptin 5 mg or 
empagliflozin 10 mg or placebo in a 1:1:1 ratio according to a randomisation plan. The 
assignment will occur in a blinded fashion via Interactive Response Technology (IRT).

At Visit 4B, patients assigned to the empagliflozin group who do not achieve an HbA1c value 
< 7% at Week 12 will be re-randomised to receive either empagliflozin 10 mg or 
empagliflozin 25 mg in a 1:1 ratio. The assignment will occur in a blinded fashion via 
Interactive Response Technology (IRT).
At Visit 5, patients assigned to the placebo group will be re-randomised to receive either 
linagliptin 5 mg or empagliflozin 10 mg or empagliflozin 25 mg in a 1:1:1 ratio according to 
a randomisation plan. The assignment will occur in a blinded fashion via IRT.
To ensure double-blind conduct, investigators will have to perform an IRT call for all patients 
at Week 14 (Visit 4B) and Week 26 (Visit 5).
Access to the codes will be controlled and documented. Technical and statistical features of 
the process of treatment allocation are described in Section 7.6.

All eligible patients will be assigned an open-label placebo run-in kit by the IRT at Visit 1B. 
As mentioned in Table 4.1.4:1 during the placebo run-in period, patients will take 3 placebo 
tablets once daily in the morning. 
Patients who qualify for randomisation will be randomly assigned by the IRT to one of the 
treatment groups listed above. Patients will take 3 tablets once daily in the morning up to 52 
weeks as detailed in Table 4.1.4: 1 Dispensation of kits by the IRT will begin at Visit 2 for 
the randomised period (double-blind, double-dummy). Dispensations will occur on 7 
occasions over 52 weeks.

Patients initially randomised to empagliflozin 10 mg and who do not achieve an HbA1c value 
< 7.0% at Week 12 will be re-randomised by the IRT to receive either empagliflozin 10 mg 
or 25 mg at Visit 4B.
For patients randomised in the placebo group, they will be re-randomised by the IRT to 
receive either linagliptin 5 mg or one of the empagliflozin doses at Visit 5.
Since patients and investigators will stay blinded, investigators will have to perform an IRT 
call for all patients at Week 14 and Week 26 in order to get new trial medication kits 
assigned.
From the start of the placebo run-in period (Visit 1B), patients should be instructed to take 
their trial medication once daily with approximately 150 ml of water. To ensure a dose 
interval of 24 hours, the study medication should be taken at the same time every day in the 
morning. If a dose is missed by more than 12 hours, that dose should be skipped and the next 
dose should be taken as scheduled. No double doses should be taken and dose reductions are 
not permitted. Study medication can be taken with or without food.
Patients should be instructed not to take their trial medication as well as metformin 
background therapy in the morning of visit days as they will be dosed whilst in the clinic. For 
visits with PK assessments (as detailed in the Flow Chart), patients who fail to do so should 
have the visit rescheduled as soon as possible, ideally on the following day. Insulin 
administration (basal and/or bolus) in the morning of clinic visits will be left to the discretion 
of the patient and/or investigator and may be dependent on planned meal intake etc. For visits 
to be performed in a fasted state, visits should be scheduled in the morning, at approximately 
the same time of day (e.g. 7am to 11am). 
Specific requirement before the visits with PK assessments (Visit 5 and 8): 
Patients will be asked to record the actual administration date and time of the last 3 doses of 
trial medication before Visit 5 and 8 on the patient diary. If a dose was missed, the date/time 
field should be left empty. These data will be transferred to the eCRF. Patients (or their 
parent(s) or legal guardian, if more appropriate) should be contacted by phone several days 
before the visit, to remind them to complete the patient diary as requested and to attend for 
the visit as arranged.
Each medication kit dispensed will include some reserve medications to allow flexibility for 
the trial visit schedule.
Site personnel will enter the medication numbers dispensed to each patient in the eCRF.

The randomisation code for DINAMOTM and DINAMOTM Mono will be kept secret by 
Clinical Trial Support up to the corresponding database lock. The bioanalytical lab will 
remain blinded during the course of the corresponding study. However, in an exceptional 
case, the bioanalytical lab may receive access to the randomisation code. In that case, 
bioanalytics will not disclose the randomisation code or the results of their measurements 
until the corresponding study is officially unblinded.
4.1.5.2
Unblinding and breaking the code
Emergency unblinding will be available to the investigator via IRT. It must only be used in
an emergency situation when the identity of the trial drug must be known to the investigator 
in order to provide appropriate medical treatment or otherwise assure safety of trial 
participants. The reason for unblinding must be documented in the source documents and/or 
appropriate eCRF page along with the date and the initials of the person who broke the code.
Due to the requirements to report Suspected Unexpected Serious Adverse Reactions 
(SUSARs), it may be necessary for a representative from Boehringer Ingelheim’ s
Pharmacovigilance group to access the randomisation code for individual patients during trial 
conduct. The access to the code will only be given to authorised Pharmacovigilance 
representatives and not be shared further.
4.1.6
Packaging, labelling, and re-supply
The investigational products will be provided by BI or a designated CRO. They will be
packaged and labelled in accordance with the principles of Good Manufacturing Practice 
(GMP). Re-supply to the sites will be managed via an IRT system, which will also monitor 
expiry dates of supplies available at the sites.
For details of packaging and the description of the label, refer to the ISF.
4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area according to the recommended storage conditions on the medication label. A
temperature log must be maintained for documentation.
If the storage conditions are found to be outside the specified range and are considered as 
unacceptable, the sponsor must be contacted immediately. Please refer to the ISF for further 
details.
4.1.8
Drug accountability
The investigator and/or pharmacist and/or investigational drug storage manager will receive 
the investigational drugs delivered by the sponsor when the following requirements are 
fulfilled:
∀
Approval of the trial protocol by the IRB / ethics committee

Investigational drugs are not allowed to be used outside the context of this protocol. They 
must not be forwarded to other investigators or clinics. Patients and legal representative(s) 
should be instructed to return unused investigational drug.
The investigator and/or pharmacist and/or investigational drug storage manager must 
maintain records of the product’s delivery to the trial site, the inventory at the site, the use by 
each patient, and the return to the sponsor or warehouse / drug distribution centre or 
alternative disposal of unused products. If applicable, the sponsor or warehouse / drug 
distribution centre will maintain records of the disposal. 
These records will include dates, quantities, batch / serial numbers, expiry (‘use- by’) dates, 
and the unique code numbers assigned to the investigational product and trial patients. The 
investigator / pharmacist / investigational drug storage manager will maintain records that 
document adequately that the patients were provided the doses specified by the CTP and 
reconcile all investigational products received from the sponsor. At the time of return to the 
sponsor and/or appointed CRO, the investigator / pharmacist / investigational drug storage 
manager must verify that all unused or partially used drug supplies have been returned by the 
clinical trial patient and that no remaining supplies are in the investigator’s possession.

OTHER TREATMENTS, EMERGENCY PROCEDURES, 
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
Background therapy
Throughout the duration of the trial, patients should continue to take their background 
therapy (metformin and/or insulin). The dose of background therapy at the time of screening 
will be recorded in the source documentation and on the appropriate pages of the eCRF. If 
medically appropriate, the dose and dosing frequency should then remain unchanged. For 
patients on insulin, the weekly average variation of the basal insulin dose should remain ≤ 0.1
IU/kg.
Background therapies will not be provided by BI as part of the clinical trial supplies, unless 
required by local laws and regulations.
For patients on insulin, investigators are advised to adjust the patient’s total insulin dose 
based on need as assessed by frequent SBGM and close patient follow-up upon initiation of 
randomised trial medication. In all cases, the actual reduction will be dependent upon 
individual glucose values. Thereafter and until the end of the trial, further adjustments to 
insulin therapy (both basal and, MDI insulin) may be implemented as necessary to avoid 
hypoglycaemia and also hyperglycaemia to ensure that, in the investigator’s opinion, the 
patient is achieving the best standard of care in accordance with local guidelines. In addition,

transfers to another type or brand of insulin as well as changes of the type of insulin pen 
should be avoided.
For patients on metformin, in case a vascular administration of iodine containing contrast 
agent is required, metformin should be temporarily discontinued as specified in the SmPC.
Rescue medication
The use of rescue medication will be permitted in this trial and will be metformin and/or 
insulin. The use of rescue medication will be permitted from the first day of treatment (after 
randomisation) until the end of the trial. 
DINAMOTM
Rescue medication (insulin or increased doses of insulin) should be initiated:
1. from the first day of treatment (after randomisation) until Week 52 in case of acute 
metabolic decompensation accompanied by significant symptoms (e.g., vomiting, 
dehydration, lethargy) and/or repeatedly elevated blood ketone (beta hydroxybutyrate) 
values > 1.5 mmol/L measured with the provided electronic device (meter), irrespective 
of the glucose value (due to its mechanism of action, empagliflozin may potentially 
modify the clinical presentation of acute metabolic decompensation, e.g. with lower blood 
glucose values than expected).
However, in case of sustained hyperglycaemia during SBGM (80% of blood glucose tests 
are > 300mg/dL (16.6 mmol/L) (non-fasting) or > 200 mg/dL (11.1 mmol/L) (fasting) for 
1 week) initiation of rescue therapy should also be considered.
2. from Week 12 (Visit 4A) until Week 52 (Visit 8) if on two successive occasions
(separated by at least 4 weeks) HbA1c is ≥9.0% and an absolute increase of HbA1c ≥ 1% 
compared with the baseline value is observed (even in the absence of symptoms related to 
hyperglycaemia and ketoacidosis). 
The type of insulin and its dosage will be left at the investigator’s discretion. 
If new insulin treatment or insulin treatment at increased doses (i.e. dose increase of basal 
insulin of more than 0.1 IU/kg above the baseline prescribed dose) continues for more than 
21 consecutive days (including the weaning phase) then the patient will be classified as 
requiring rescue therapy.
DINAMOTM Mono
Rescue medication (metformin and/or insulin) should be initiated:
-
at anytime in case of acute metabolic decompensation;
-
if HbA1c > 7.0% AND
o
there is no HbA1c decrease at Week 12
o
the HbA1c decrease is less than 0.5% at Week 26 and later
In addition, rescue medication could be initiated at any time as per the investigator’s 
judgement. The type of insulin and its dosage as well as the dosage of metformin will be left 
at the investigator’s discretion.

On top of the HbA1c measurements performed at the time points defined in the Flowchart, 
additional HbA1c measurements can be performed at any time if deemed necessary by the 
investigator. Besides, additional interactions (e.g. phone calls, text messaging or emails, as 
deemed appropriate by the investigator and the patient) must be planned every 4 weeks 
between 2 visits where the interval exceeds 4 weeks.
Furthermore, some patients may require use of insulin due to temporary medical conditions 
such as hospitalisation or intercurrent illness. Any type or dose of insulin can be used at the 
discretion of the investigator. In such cases, an attempt is made to withdraw insulin once the 
acute event has resolved. In the case of a temporary medical condition such as hospitalisation 
or intercurrent illness, weaning occurs within 2 weeks if the event lasted 2 weeks or less; if 
the event lasted more than 2 weeks, weaning occurs within 1 month. Withdrawal of insulin 
occurs regardless of blood glucose values; if metabolic decompensation occurs, appropriate 
safety procedures are followed as detailed in Section 5.3.5.3.
In the case of hypoglycaemia that may put patient on risk (e.g. repeated symptomatic 
hypoglycaemia or severe hypoglycaemia), appropriate adjustment of oral antidiabetic therapy
and/or insulin therapy such as a dose reduction / discontinuation of ongoing rescue 
medication or existing background therapy should be initiated. Reduction or discontinuation 
of ongoing rescue medication should be considered before a reduction in the dose of existing 
background therapy.
Any rescue medication or dose change in background therapy will be recorded in the source 
documents and on the appropriate pages of the eCRF.
Any additional treatment that does not qualify as a rescue medication and is considered as 
deemed necessary for the patient’s welfare may be given at the investigator’s discretion. 
Exceptions to this are the restrictions described in section 4.2.2.1.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
With the exception of metformin and insulin used as background therapy, in any other 
situation than rescue condition, the use of any other antidiabetic agents will be prohibited 
during the course of the trial. As described in section 4.2.1, insulin is also allowed as rescue 
medication.
Additionally, weight reduction medications and long-term use of systemic corticosteroids
(more than 1 week) are prohibited due to their influence on glucose metabolism. However, 
therapy with non-systemic corticosteroids such as inhaled or local use will be permitted.
Furthermore, for patients taking thyroids hormones, any dose change should be avoided. If 
such dose change does occur, it should be recorded in the source documents and onto the 
appropriate eCRF page.

4.2.2.2
Restrictions on diet and life style
All patients and their families must be encouraged to make dietary changes consistent with 
healthy eating recommendation, including counselling for weight reduction, reduced 
carbohydrate and total and saturated fat intake, increased fiber intake and increased physical 
activity along with decreased sedentary behaviors.
Smoking is not permitted prior to or during any of the visits (from the start of the overnight 
fast that precedes visits). Any alcohol intake should be avoided within 2 days prior to each 
visit.
4.2.2.3
Restrictions regarding women of childbearing potential
Women of childbearing potential must use the contraception methods described in the 
patient’s legal representative information sheet. 
In the unexpected and rare cases where women are not of childbearing potential because they 
are permanently sterilised, they do not need to use contraception to be eligible for the trial. 
All other female patients are considered to have childbearing potential and must use adequate 
contraception throughout the trial (from screening until 3 weeks after the last dose of trial 
medication). 
Adequate contraception is defined per ICH M3 (R2) as highly effective or acceptable 
methods. Highly effective methods of birth control which should be used by women of 
childbearing potential are those, which alone or in combination, result in a low failure rate 
(i.e., less than 1% per year) when used consistently and correctly, and must be in accordance 
with local regulations where applicable. 
Based on the recommendations of the European Union Heads of Medicines Agency related to 
contraception and pregnancy testing in clinical trials (CTFG, 2014), the following 
contraception methods can achieve a failure rate of less than 1% per year when used 
consistently and correctly: 
1. Use of hormonal methods of contraception associated with inhibition of ovulation 
a. Combined (estrogen and progestogen containing) hormonal contraception: 
• Oral 
• Intravaginal 
• Transdermal 
b. Progestogen-only hormonal contraception: 
• Oral 
• Injectable 
• Implantable 
2. Placement of intrauterine device or intrauterine system. 
3. Bilateral tubal occlusion 
4. Male sterilization (with the appropriate post-vasectomy documentation of the absence of 
sperm in the ejaculate) 
5. Complete sexual abstinence

TREATMENT COMPLIANCE
Patients are requested to bring all remaining trial medication including empty package 
material with them when attending visits.
Based on counts, treatment compliance will be calculated as shown in the formula below.
Compliance will be verified by CRA authorised by the sponsor.
Treatment compliance (%) =
Number of actually taken # 100
     Number of which should have been taken
Compliance during the open-label placebo run-in period must be between 75% and 125%. If 
compliance is outside this range, the patient should not be randomised as described in section 
3.3.2.
Compliance during the randomised period should also be between 75% and 125%. 
Patients who are not compliant with their medication should be carefully interviewed and 
informed about the purpose and the conduct of the trial. This discussion should be 
documented.

ASSESSMENT OF EFFICACY
5.2.1
HbA1c and fasting plasma glucose (FPG)
HbA1c and FPG will be analysed by the central laboratory at the time points indicated in the 
Flow Chart. However, due to the COVID-19 pandemic, HbA1c and FPG may be analysed by
the local laboratory.
The samples will be analysed at a central laboratory or its affiliates having a National 
Glycohemoglobin Standardisation Program (NGSP) Level I certificate. HbA1c results will be 
reported in both NGSP (%) and International Federation of Clinical Chemistry, IFCC 
(mmol/mol) units. The relationship between HbA1c results from the NGSP network (% 
HbA1c) and the IFCC network (mmol/mol) has been evaluated and a master equation has 
been developed (NGSP = [0.09148*IFCC] + 2.152). This relationship is continuously 
monitored and any changes are investigated. The NGSP certification process and test results 
for NGSP-certified methods do not change as a result of the IFCC standardisation of HbA1c, 
and will continue to be directly traceable to the Diabetes Control and Complications Trial 
(DCCT) reference and now also the IFCC reference. If a centrally analyzed, NGSP-certified 
hemoglobin A1c assay is unavailable (e.g. due to the COVID-19 pandemic), an HbA1c assay 
performed at a local laboratory is acceptable.
Further details about HbA1c sample handling, shipment, and assay procedures can be found 
in the laboratory manual in the ISF.
Blood samples for the determination of FPG at the central laboratory will be taken after an
overnight fast (no food or drinks except for water for at least 8 hours). The samples should be 
taken before trial medication administration. The samples will be measured at a central
laboratory using validated assays. Plasma glucose results will be reported in mmol/l and 
mg/dl.
Further details about FPG sample handling and shipment can be found in the laboratory 
manual in the ISF.
5.2.2
Body weight
Body weight measurements should always be done on the same calibrated scales for an 
individual patient at the time points indicated in the Flow Chart.  However, due to the 
COVID-19 pandemic, body weight measurements may be done at the local laboratory.
In order to get comparable body weight values, it should ideally be performed in the 
following way:
∀
fasting (at visits to which a patient has to come fasted, see Flow Chart)
∀
after bladder voiding
∀
shoes and coat/jackets should be taken off
∀
pockets should be emptied of heavy objects (i.e. keys, coins etc.)

5.2.3
Systolic/diastolic blood pressure (SBP and DBP) and heart rate (vital signs)
SBP and DBP as well as heart rate (electronically or by palpation, count for 1 minute) will be 
measured at the time points indicated in the Flow Chart with a calibrated electronic 
sphygmomanometer. The BP measurement should be performed three times at each time 
point and the mean value of the measurements will be analysed.  However, due to the 
COVID-19 pandemic, vital signs may be done at the local laboratory.  
Initially, BP should be taken 3 times in both arms. The arm with the higher average pressure 
(systolic or – if equal – diastolic) should be used for subsequent measurements; if 
measurements for both arms are equal, the non-dominant arm should be chosen.
BP measurements should always be performed on the same arm and, if possible, by the same
person and using the same device. The same method must be used throughout the trial for a
given patient i.e. if a patient receives the first BP measurement for example with an electronic
device, the same method and device should be used throughout the study for this patient.
After patients have rested quietly, in the seated position for at least 5 minutes, 3 BP
measurements will be taken approximately 2 minutes apart. The seated pulse rate should be
from the second BP reading.
BP measurements should be recorded to the nearest 1 mmHg. BP should always be measured 
before any blood samples are taken.

ASSESSMENT OF SAFETY
5.3.1
Physical examination
A complete physical examination will be performed at the time points specified in the Flow 
Chart. It includes at a minimum general appearance, neck, lungs, cardiovascular system, 
abdomen, extremities, and skin. 
The results must be included in the source documents available at the site. 
Throughout the physical examination, the privacy of the patient will be respected and local 
culture/requirements will be taken into consideration (e.g. same sex chaperone or same sex 
doctor performing the examinations).
For patients on insulin, injection sites should be checked regularly.
5.3.2
Vital signs
Please refer to Section 5.2.3.
5.3.3
Safety laboratory parameters
Safety laboratory parameters to be assessed are listed in Table 5.3.3: 1 and Table 5.3.3: 2. For 
the sampling time points please see the Flow Chart.

All analyses will be performed by a central laboratory, or at a local laboratory at designated 
visits per the Flow Chart under exceptional circumstances due to the COVID-19 pandemic, 
the respective reference ranges will be provided in the ISF. 
For Visit 2, Visit 5 and Visit 8, all safety laboratory samples will be collected from the 
patient after an overnight fast (i.e. nothing to eat or drink except water for at least 8 hours). 
When applicable, laboratory samples should be collected before trial medication is taken.
To minimise pain and distress, local anaesthetic product will be offered to all patients before 
any venepuncture is carried out. 
For female patients, pregnancy testing will be performed locally using the urine pregnancy 
test kits supplied by the central laboratory or local laboratory under exceptional 
circumstances due to the COVID-19 pandemic. Immediately after the result of a pregnancy 
test is known, the pregnancy test kit will be discarded at the site. In case of positive result, a 
serum pregnancy test will be performed by the central laboratory, or at a local laboratory 
under exceptional circumstances due to the COVID-19 pandemic. The results of the test must 
therefore be documented in the source documents available at the site for future verification 
by the CRA.
Instructions regarding sample collection, sample handling/ processing and sample shipping 
are provided in the Laboratory Manual in the ISF. 
Laboratory reports will be provided through the central laboratory web-based system. It is the 
responsibility of the investigator to retrieve and evaluate the laboratory reports. Clinically 
relevant abnormal findings as judged by the investigator will be reported as adverse events 
(please refer to Section 5.3.6.2).
In case the criteria for hepatic injury are fulfilled, a number of additional measures will be 
performed (please see Section 5.3.6.2 and the DILI Checklist provided in the eDC system). 
The amount of blood taken from the patient concerned will be increased due to this additional 
sampling. The central laboratory will transfer the results of the analysis to the sponsor.

Follow-up on suspicion for urinary tract infection (UTI) and genital infection
Patients having a history of chronic/recurrent UTI or genital infection or an acute episode of 
UTI or genital infection at screening will be identified and this condition must be documented 
as medical history or as a baseline condition in the eCRF, respectively.
Throughout the trial, patients should be closely observed for symptoms of UTI or genital 
infection. In case these symptoms occur, symptomatic relief and anti-infectives should be 
provided as appropriate [c01678844-17].
For documentation of acute UTI during trial conduct, the following measures have to be 
taken. In any case of suspected UTI (symptomatic or asymptomatic), a dipstick test 
(leukocyte esterase [for WBC] and nitrite) will be performed at the site at the time points 
indicated in the Flow Chart. In case of a positive result at site, a urine culture sample must be

IGF-1, IGF-BP3 and markers of bone turnover
IGF-1, IGF-BP3 and bone metabolism biomarkers will be measured by the central lab at the 
time points indicated in the Flow Chart. 
The following markers of bone turnover will be measured:
∀
Calcium
∀
Phosphate
∀

IGF-1 and IGF-BP3 will be measured in samples collected from the patient after an overnight 
fast (i.e. nothing to eat or drink except water for at least 8 hours).
5.3.4
Electrocardiogram
The 12-lead ECGs will be recorded as scheduled in the Flow Chart. The investigator or a 
designee will evaluate whether the ECG is normal or abnormal and whether it is clinically 
relevant, if abnormal. ECGs may be repeated for quality reasons and the repeated recording 
used for analysis. 
Additional ECGs may be recorded for safety reasons. Dated and signed printouts of ECG 
with findings should be documented in patient’s medical record.
Clinically relevant abnormal findings will be reported either as baseline condition (if 
identified at the screening visit) or otherwise as adverse events and will be followed up 
and/or treated as medically appropriate.

at home during the study for self-measurement of blood glucose. Instructions on the proper 
use of the SBGM equipment will be provided by the site staff. The patient or his/her 
parent(s)/legal guardian will be asked to enter data from the device to a patient diary. The 
investigator or delegated site personnel should also print out the record list and include it in 
the patient medical records. To avoid additional finger pricks for blood glucose measurement, 
patients with a continuous glucose monitoring (CGM) device can use relevant readings from 
the device following the minimum testing requirements below. It is the PI discretion to report 
clinically relevant readings as adverse events. It is also the PI discretion regarding patient 
diary management entry as long as the minimum testing requirements below are met.
Only in case of linked adverse events, the single value from the glucometer will be recorded 
in the eCRF.
SBGM should be performed regularly and ideally its frequency should be individualised as 
per local clinical guidelines. Especially for patients on insulin, more frequent SBGM may be 
performed. Nevertheless, minimum requirements are defined by this clinical trial protocol 
and are as follows:
∀
Placebo run-in period
Daily SBGM in a fasted state is recommended.
∀
Randomised treatment period
SBGM at least 3 times per week in a fasted state is recommended.
∀
Follow-up period
At least one SBGM per week in a fasted state is recommended. 
Throughout the trial, additional blood glucose measurements may be performed any time the 
patient is symptomatic, i.e. experiences signs/symptoms of hyper- or hypoglycaemia.
5.3.5.3
Self-blood ketone monitoring
Patients will be equipped with an electronic device to determine their ketone concentration 
(i.e. the electronic blood glucose monitoring device/meter that is also capable of measuring 
blood ketones). The patient or his/her parent(s)/legal guardian will be asked to enter data 
from the device to a patient diary. The investigator or delegated site personnel should also 
print out the record list and include it in the patient medical records. 
Patients should be instructed to test their ketones in case of any symptoms of DKA, e.g. 
nausea, vomiting, abdominal pain etc., irrespective of the glucose value. Patients must be 
reminded about the signs and symptoms of DKA, on the interpretation of ketone values 
measured via the meter, and on appropriate action to take in the event of increased ketone 
levels (see below). 
Daily measurements before breakfast are recommended during the first 4 weeks of the 
treatment period and during the 4 subsequent weeks after Visit 5. Otherwise, measurements 
should be performed at least 3 times per week. In addition, blood ketone levels will be 
checked by using the meter at most clinic visits (see Flow Chart).

Daily blood ketone monitoring should also be performed in case of concomitant illness/stress 
or if deemed necessary by the investigator. In the event of increased ketones (> 0.6 mmol/l), 
patients should contact their trial site. In case of deteriorating ketosis, blood glucose and 
ketone levels should be checked every 1-2 hours until they are back in a range considered to 
be normal for the patient. Patients should be instructed to immediately refer themselves to 
hospital and/or the investigator, or to contact an emergency physician, in case of a blood 
ketone concentration > 1.5 mmol/L (as indicated in the meter manual). Blood ketone 
concentration > 1.5 mmol/L should be reported as AE by the investigator and the blood 
ketone values should be recorded in the eCRF. 
In case of a suspected DKA, the investigator should ensure that appropriate tests are 
performed at the earliest opportunity according to local guidelines, such as a blood gas test 
(pH, bicarbonate). The results will be collected on the relevant page of the eCRF.
Investigators should also differentiate deteriorating ketosis/DKA from any mild to moderate 
increase of ketones which may be seen due to the mechanism of action of empagliflozin, 
especially in the fasted state (e.g. in the morning). In accordance with Section 3.3.2, 
investigators should carefully select patients for the study in terms of their ability to comply 
with ketone measurement requirements. Patients not adhering to the instructions given by the 
investigator should be retrained at the earliest possible opportunity.
5.3.5.4
C-peptide
Laboratory samples for C-peptide will be collected at the time points indicated in the Flow 
Chart.
Except for the screening visit, samples will be collected from the patient after an overnight 
fast (i.e. nothing to eat or drink except water for at least 8 hours). When applicable, samples 
should be collected before trial medication is taken.
The analysis will be performed by a central laboratory. Non-fasting serum C-peptide at Visit 
1A will be used to check the patient eligibility as described in Section 3.3.1. The respective 
reference ranges and details about sample handling and shipment will be provided in the 
laboratory manual in the ISF.
5.3.5.5
Tanner staging (modified)
Tanner staging is a scale of pubertal development in children, adolescents and adults which is 
routinely used for defining physical measures of development based on external primary and 
secondary sex characteristics, such as the size of the breasts, genitalia and development of 
pubic hair. Due to natural variation, individuals pass through the Tanner stages at different 
rates depending on the timing of puberty.
To assess the stage of puberty of each patient throughout the trial, a modified version of this 
scale will be used at the time points indicated in the Flow Chart. For patients with Tanner 
stage V at Visit 2, further assessment is not required at the subsequent visits. For details 
regarding the modified Tanner staging, please refer to Appendix 10.1.

5.3.5.6
Criteria for hypoglycaemic event
Every episode of plasma glucose equal to or below 70 mg/dl (3.9 mmol/l) should be 
documented in the eCRF with the respective time and date of occurrence. Any 
hypoglycaemia with glucose values < 54 mg/dl (< 3.0 mmol/l) as well as all symptomatic and 
severe hypoglycaemic event (requiring active assistance by another person to administer 
carbohydrate) should be documented with the respective time and date of occurrence as an 
AE "hypoglycaemic event".
For the analysis, all hypoglycaemias will be classified according to the following criteria:
∀
Documented symptomatic hypoglycaemia AE with glucose concentration < 70 mg/dL 
(< 3.9 mmol/L), as well as asymptomatic hypoglycaemia event < 70 mg/dL  (< 3.9 
mmol/L)
∀
Documented any hypoglycaemia AE with glucose concentration < 54 mg/dL (< 3.0 
mmol/L)
∀
Severe hypoglycaemia AE: event requiring the assistance of another person to 
actively administer carbohydrates, glucagon or take other corrective actions. Plasma 
glucose concentrations may not be available during an event, but neurological 
recovery following the return of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration 
[R17-0216].
5.3.6
Assessment of adverse events
5.3.6.1
Definitions of AEs 
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:
∀
results in death,
∀
is life-threatening, which refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe.
∀
requires inpatient hospitalisation or 
∀
requires prolongation of existing hospitalisation,
∀
results in persistent or significant disability or incapacity, or
∀
is a congenital anomaly / birth defect, or

∀
is deemed serious for any other reason if it is an important medical event when based 
on appropriate medical judgement which may jeopardise the patient and may require 
medical or surgical intervention to prevent one of the other outcomes listed in the 
above definitions.
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in 
hospitalisation or development of dependency or abuse. 
AEs considered “Always Serious”
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the drug and must be reported as 
described in Section 5.3.6.2, subsections “AE Collection” and “AE reporting to sponsor and 
timelines”.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which by their nature, can always be 
considered to be “serious” even though they may not have met the criteria of an SAE as 
defined above.
The latest list of “Always Serious AEs” can be found in the eDC system. These events should 
always be reported as SAEs as described above.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. 
AESIs need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAEs.
Protocol-specified AESIs (as identified by the investigator based on the below list for adverse 
events of special interest) can be classified as serious or non-serious but all these AESIs once 
identified by the investigator must be reported on an SAE form in an expedited manner 
similar to SAEs, even if they do not meet any of the SAE seriousness criteria (i.e. non serious 
AESI should be reported as a non-serious event on the SAE form for reporting).
The following events are considered as protocol-specified adverse events of special interest 
(AESI):
∀
Hypersensitivity reactions such as angioedema, angioedema-like events, and 
anaphylaxis (an identified risk with DPP-4 inhibitors)
∀
Skin lesions such as exfoliative rash, skin necrosis, or bullous dermatitis (a potential 
risk with DPP-4 inhibitors)
∀
Pancreatitis (an identified risk with DPP-4 inhibitors)
∀
Pancreatic cancer (a potential risk with DPP-4 inhibitors)
∀
Hepatic injury (of potential interest for all investigational drugs)
∀
Decreased renal function (of potential interest for all investigational drugs)
∀
Diabetic Ketoacidosis (DKA) (an identified risk with SGLT-2 inhibitors)

Events involving lower limb amputation (a potential risk with SGLT-2 inhibitors)
Details on hepatic injury, decreased renal function, DKA and events involving lower limb 
amputation are provided below.
Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory parameters after 
randomisation: 
∀
an elevation of AST and/or ALT ≥3 fold ULN combined with an elevation of total 
bilirubin > 2 fold ULN measured in the same blood draw sample, and/or
∀
isolated elevation of ALT and/or AST ≥ 5 fold ULN
These laboratory findings constitute a hepatic injury alert and the patients showing these 
laboratory abnormalities need to be followed up according to the “DILI checklist” provided 
in the eDC system. 
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, 
unexplained coagulopathy, right upper quadrant abdominal pain, etc.) without lab results 
(ALT, AST, total bilirubin) available, the investigator should make sure these parameters are 
analysed, if necessary in an unscheduled blood test. Should the results meet the criteria of 
hepatic injury alert, the procedures described in the “DILI checklist” should be followed.
Decreased renal function
Decreased renal function diagnosed as acute kidney injury or defined by a creatinine value 
showing a ≥ 2 fold increase from baseline and is above the ULN.
For the AESI “decreased renal function” the investigator shall collect an unscheduled 
laboratory sample for creatinine as soon as possible and initiate follow-up laboratory tests of 
creatinine according to medical judgement.
Diabetic ketoacidosis (DKA)
DKA is defined by the diagnostic criteria in Table 5.3.6.1: 1 below, and as defined by the 
American Diabetes Association (ADA) [R14-5435].
Investigators should note that not all criteria in the table below need to apply for the diagnosis 
of DKA, and clinical judgement should also be taken into consideration. Due to its 
mechanism of action, empagliflozin may potentially modify the clinical presentation of DKA 
which may occur at lower plasma glucose levels than stated in Table 5.3.6.1: 1 below 
(see Sections 1.2.1 and 2.3 for further details).

Events involving lower limb amputation
This definition includes amputation (i.e. resection of a limb through a bone), disarticulation 
(i.e. resection of a limb through a joint) and auto-amputations (i.e. spontaneous separation of 
non-viable portion of the lower limb).
Not included in this definition are debridement (removal of callus or dead tissue), procedures 
on a stump (like stump revision, drainage of an abscess, wound revision etc.) and other 
procedures (e.g. nail resection or removal) without a concomitant resection of a limb 
(amputation or disarticulation).
Each lower limb amputation, disarticulation, or auto-amputation should be reported 
separately. The SAE report should include the date of the procedure, the level of amputation 
or disarticulation, the medical condition(s) leading to the procedure and if the patient had 
some of the known risk factor(s) for lower limb amputation.
In addition to the safety topics defined as AESI above, the following safety topics will be 
monitored during the trial and assessed:  Arthralgia, bullous pemphigoid, genital infections 
(including mycotic infections, such as vulvovaginal or balanitis), bone fracture, urinary tract 
infections (including urosepsis or pyelonephritis), AEs related to reduced intravascular 
volume and osmotic diuresis (including symptomatic hypotension).
Intensity of AEs
The intensity of the AE should be judged based on the following:

Mild:
Awareness of sign(s) or symptom(s) that is/are 
easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual 
activities
Causal relationship of AEs
Medical judgement should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history. 
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:
∀
The event is consistent with the known pharmacology of the drug.
∀
The event is known to be caused by or attributed to the drug class.
∀
A plausible time to onset of the event relative to the time of drug exposure.
∀
Evidence that the event is reproducible when the drug is re-introduced.
∀
No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).
∀
The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).
∀
An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:
∀
No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned).
∀
Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives).
Of note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.
∀
Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).
∀
Disappearance of the event even though the trial drug treatment continues or remains 
unchanged.

The following must be collected and documented on the appropriate eCRF page(s) by the 
investigator:
∀
From signing the informed consent onwards until individual patient’s end of trial: 
-all AEs (serious and non-serious) and all AESIs.
∀
After the individual patient’s end of trial: 
the investigator does not need to actively monitor the patient for AEs but should only 
report related SAEs and related AESIs of which the investigator may become aware of 
by any means of communication, e.g. phone call. Those AEs should however, not be 
reported in the eCRF.
Figure 5.3.6.2: 1
Trial periods for collection of AEs
Patients who discontinue trial medication prematurely and agree to be contacted further, but 
do not agree to physical visits should be followed up as described in section 3.3.4.1. From the 
individual patient’s end of the trial the investigator must report all deaths/fatal AEs regardless 
of relationship, related SAEs and related AESIs the investigator becomes aware of.
AE reporting to sponsor and timelines
The investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form immediately (within 24 hours) to the sponsor’s 
unique entry point (country specific reporting process will be provided in the ISF). The same 
timeline applies if follow-up information becomes available. On specific occasions the 
investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and send the BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the investigator should provide the information requested on the appropriate 
eCRF pages and the BI SAE form, if applicable. The investigator should determine the causal 
relationship to the trial medication and any possible interactions between the trial medication 
and a Non-Investigational Medicinal Product (NIMP) / Auxiliary Medicinal Product (AMP).

The following should also be recorded as an (S)AE in the CRF and BI SAE form (if 
applicable):
∀
Worsening of the underlying disease or of other pre-existing conditions 
∀
Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the investigator.
If such abnormalities already pre-exist prior to trial inclusion they will be considered as 
baseline conditions and should be collected in the eCRF only. All (S)AEs, including those 
persisting after individual patient’s end of trial must be followed up until they have resolved, 
have been assessed as “chronic” or “stable”, or no further information can be obtained.
Pregnancy
In rare cases pregnancy might occur in a clinical trial. Once a patient has been enrolled in the 
clinical trial and has taken trial medication, the investigator must report any drug exposure 
during pregnancy in a trial participant immediately (within 24 hours) by means of Part A of 
the Pregnancy Monitoring Form to the sponsor’s unique entry point. 
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form 
is to be completed. If there is an SAE and/or AESI associated with the pregnancy an SAE 
form must be completed in addition.

drug administrations on the 3 days prior to Visit 5 and 8 have to be recorded as well (see 
Section 4.1.4).
5.4.2
Methods of sample collection
The planned PK analyses will require blood sampling at the time points indicated in the 
Flowchart. Correct, complete and legible documentation of drug administrations and blood 
sampling times as well as adequate handling and identification of PK samples are mandatory 
to obtain data of adequate quality for the PK analysis.
In order to allow the sample identification, the sample tube labels should list at a minimum 
the following information: BI trial number, patient number, visit number and planned 
sampling time. Two x 2 plasma aliquots will be obtained from blood samples (two aliquots 
for empagliflozin analysis, and two aliquots for linagliptin analysis). Each aliquot should 
contain at least 0.5 mL plasma. All aliquots will be stored at about -20°C or below and be 
shipped on dry ice. 
Further details on sample collection, preparation of plasma aliquots, sample handling, and 
shipping are provided in the ISF and/or lab manual.
5.4.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of analyte plasma concentrations, blood will be taken from an antecubital 
or forearm vein into a blood drawing tube that contains potassium EDTA–anticoagulant at 
the time points indicated in the Flowchart. Blood will be withdrawn by means of either an 
indwelling venous catheter or by venipuncture with a metal needle. If a forearm vein cannot 
be used for any reason, then the most easily found vein can be used instead. It is 
recommended to use local anesthetics for the skin to avoid pain upon blood withdrawal. 
Attempts to draw blood are limited to three.
During the whole trial, a maximum of approximately 16 mL of blood will be drawn for PK 
purposes. Plasma samples will be obtained by centrifugation. Sample aliquots will be stored 
at the trial site and at the logistics central laboratory until shipment and at the analytical 
laboratory until analysis. First and second sample aliquots are to be shipped separately. For 
further details please refer to the ISF and/or lab manual. 
The trial samples will be discarded after completion upon the final study report has been 
signed.

OTHER ASSESSMENTS
5.6.1
Auto-antibodies for diabetes
Auto-antibodies can be detected early in the development of type 1 diabetes and are 
considered as markers of autoimmune beta cell destruction. In conjunction with the 
measurement of C-peptide levels, the presence of T2DM will be confirmed at Visit 1A in all 
trial patients by measuring auto-antibodies to IA-2 and glutamic acid decarboxylase auto-
antibodies (GADA).
The analysis will be performed by a central laboratory. The details about sample handling 
and shipment will be provided in the laboratory manual in the ISF.
5.7
APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are considered standard measurements in the 
clinical development of non-insulin products such as empagliflozin and linagliptin, and/or 
standard as part of routine care for T2DM [P12-09397]. All defined measurements will be 
performed in order to monitor safety and tolerability aspects and to determine efficacy in an 
appropriate way.
A surrogate endpoint (i.e. the laboratory parameter HbA1c) is used as the primary efficacy 
endpoint, since for the purposes of drug approval and labelling, which will support an 
indication of glycaemic control, regulatory authorities state that this endpoint, albeit 
surrogate, is the primary endpoint of choice [R08-2669].

INVESTIGATIONAL PLAN
Visits should take place at a location within the clinical site that has a child-friendly 
infrastructure (e.g. an environment that is familiar to the patients, the setting is physically 
appropriate, if desired by the patient, parent(s)/legal guardian are allowed to stay with them 
during the trial procedures). Furthermore, site-personnel should be knowledgeable and skilled 
in dealing with the paediatric population and its age-appropriate needs. However, Visits 3, 
4A, 6, 7, 9 can be done remotely/by telephone/telemedicine under exceptional circumstances 
due to the COVID-19 pandemic. Reasons a remote/telephone/telemedicine visit may be 
performed may include a confirmed or suspected COVID-19 infection or unwillingness to 
return to the investigator site due to concerns of COVID-19 exposure.
6.1
VISIT SCHEDULE
Trial visits should start between 7.00 AM and 11.00 AM and ideally should be scheduled as 
early as possible when overnight fast is required (at least 8 hours with no food or drink and 
water only).
Smoking is not permitted prior to or during any of the visits (this includes from the start of 
the overnight fast that precedes all visits). Excessive food and alcohol intake should be 
avoided in the 2 days prior to each visit.
All patients are to adhere to the visit schedule as specified in the Flow Chart. Some flexibility 
is allowed in scheduling the visits according to the visit time windows as specified. The trial 
medication kits will contain sufficient medication to allow for these protocol-permitted visit 
windows. All deviations from the planned visit schedule will be documented. If any visit has 
to be re-scheduled, subsequent visits should follow the original visit schedule (calculated 
from Visit 2).
If a patient mistakenly takes trial medication in the morning of a visit where blood samples 
are drawn for PK assessment or comes in non-fasted where a fasting condition is required, the 
visit should be re-scheduled to the next day reminding the patient about the expected 
conditions. 
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
Study procedures to be performed at each visit are listed in the Flow Chart. Study procedures 
should be performed in the same order as in the Flow Chart. Blood pressure and pulse rate as 
well as 12-lead ECG should always be measured before any blood samples are drawn. 
Weight should be measured after urine sampling.
Additional details regarding visit procedures are provided below. 
6.2.1
Screening and run-in period(s)
No trial procedure is allowed unless the appropriate consent and assent are in place. Consent 
and assent must be obtained prior to the screening visit procedures.

Screening Period (Visit 1A to 1B)
Visit 1A is the beginning of the screening period. The patient should be recorded on the
enrolment log and be registered in the IRT as a screened patient when Visit 1A is performed.
Once Visit 1A procedures are complete and laboratory results are received, 
inclusion/exclusion criteria must be reviewed. If the patient meets inclusion/exclusion
criteria, he/she should be contacted to schedule the next visit.
If the patient does not meet inclusion/exclusion criteria, the patient must be recorded in eCRF 
as a screen failure. Patient must be registered as a screen failure in IRT.
Run-in Period (Visits 1B to 2)
Visit 1B is the beginning of the run-in period. This visit can be performed on the same day as 
Visit 1A.
Following completion of Visit 1B procedures, eligible patients will be dispensed a placebo 
run-in kit for the 2 week run-in period which will be assigned via the IRT system. 
The SBGM/SBKM device is delivered to the patient at Visit 1B. Only blood glucose 
measurements are expected during the run-in period. The measures have to be captured by 
the patient or his/her legal representative in a paper diary every day during run in period.
Medical History
Any pre-existing medical conditions considered as relevant by the investigator, excluding the 
indication of the trial, are recorded into the eCRF in the appropriate page. This concern all 
active pathology, chronic disease or recurrent event.
6.2.2
Treatment period(s)
For patients eligible to be randomised, assessments should be performed as mentioned in the 
Flow Chart and the respective protocol sections.
Visits 2, 5 and 8 have to be performed in a fasted state (overnight fast for at least 8 hours, no
food intake, only water allowed).
Initial randomisation at Visit 2
Eligible patients will be randomised by using the IRT system; all visit assessments should 
have been completed prior to this, and before the first intake of study medication. First dose 
of trial drugs will be administered in the clinic (Day 1).
Starting from Visit 2, the SBGM/CGM/SBKM device will also be used by the patient to 
measure his/her blood glucose concentration and blood ketone concentration before 
breakfast. He/she or his/her parents/legal guardian should enter the values in the patient diary.
Those values will then be reviewed by the investigator or delegated site personnel at each 
clinic visit. In order to make sure those measurements are well performed, the investigator or 
a delegated site staff representative should contact the patient or the parent/legal guardian by 
phone/text message/email a day or two after randomised treatment is started and then after 2, 
8, 18, 22, 34, 38, 46 and 50 weeks of treatment.

These measurements should be performed as described in the Flow Chart and in Section 
5.3.5.2 and 5.3.5.3.
Next clinic visits will be scheduled after 4, 12, 14, 26, 30, 42 and 52 weeks of treatment 
(Visit 3 to 8). For detailed description of the trial procedures at each visit and dispensing 
schedule, please refer to the Flow Chart.
Re-randomisation at Visit 4B (Week 14)
Patients not achieving an HbA1c value < 7.0% at Visit 4A (as measured by the central 
laboratory) and initially randomised to empagliflozin 10 mg will be re-randomised to receive 
either empagliflozin 10 mg or empagliflozin 25 mg. In order to maintain the blinding, an IRT 
call will be performed for all patients. Medication numbers will be assigned through the IRT 
system based on the HbA1c value at Visit 4A and the age at baseline.
Visit 4B could be a site visit or medication kits could be delivered at the patient’s home by a 
dedicated study nurse/study site staff/delegated courier at the investigator’s discretion and as 
per the local regulations. In case the medication kits would be delivered at the patient’s home, 
a phone contact should be performed by a site staff representative. Following completion of 
the visit procedures, eligible patients will be re-randomised and the first dose of re-
randomised trial drugs should be administered on the same day.
Re-randomisation at Visit 5 (Week 26)
After the 26-week treatment period, all patients will enter a double-blind safety extension 
period up to 52 weeks. 
Patients who received placebo during the 26-week treatment period will be re-randomised to 
receive either linagliptin 5 mg or empagliflozin 10 mg or empagliflozin 25 mg. The re-
randomisation will be stratified by age at baseline. At Visit 5, in order to preserve the trial 
blinding, the investigator will assign medication kits for all patients through the IRT system.
Following completion of the visit procedures, eligible patients will be re-randomised and the 
first dose of re-randomised trial drugs should be administered on the same day
6.2.3
Follow Up Period and Trial Completion
For patients who complete treatment as planned, a follow-up (FUP) visit should be planned 3 
weeks after last trial drug administration. For detailed description of the trial procedures at 
the FUP visit, please refer to the Flow Chart.
Trial completion
The trial completion eCRF end-of-study page has to be filled-in when the patient has 
terminated the trial.

treatment as planned;
•
After the early unscheduled end of treatment (EOT) visit, if a patient did not agree to 
come to the remaining planned study visits and also disagrees to be contacted at all;

agree to be contacted/allow access to medical records.
Patients who prematurely discontinued trial medication
Patients who prematurely discontinue study drug (refer to section 3.3.4) before the planned 
end of treatment at Visit 8, should come to the clinic as soon as possible after last drug intake 
for an immediate unscheduled early EOT visit. The reason for premature trial drug 
discontinuation must be documented in the eCRF. For detailed description of the trial 
procedures at this visit, please refer to the Flow Chart.
In addition patients will be encouraged to attend all subsequent planned visits despite not 
being under treatment anymore and perform all study procedures except pharmacokinetic 
sampling.
Study assessments may be omitted if a patient is willing to return to the pre-defined study 
visits, with exception of blood drawing for safety lab tests, HbA1c and FPG, body weight, 
blood pressure and collection of adverse events, and concomitant therapy.
The need for coming to future visits in case of premature discontinuation of trial medication
will be explained to patients prior to their participation in the trial.
Vital status information
In case of early discontinuation of trial medication, if the patient does not agree to come to
future visits as planned,every attempt will be made to get information on vital status at Week
55 after his/her randomisation.
Patients and parents/legal guardian will be asked to agree to be contacted by the site 
personnel, which could be by telephone calls, to allow collection of this information.
If death occurs, the investigator will review the circumstances, including the relevant medical
records to ascertain the most likely primary and secondary causes of death.
Collection of vital status will be performed in accordance with national ethical and regulatory
guidelines. The need for vital status information will be explained to patients prior to their
participation in the trial.

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
This is a multinational, randomised, placebo-controlled, double-blind trial to assess the 
efficacy and safety of pooled empagliflozin (empagliflozin 10 mg and empagliflozin 25 mg)
and linagliptin 5 mg versus placebo after 26 weeks of treatment in children and adolescents
with T2DM.
7.1.1
DINAMO
The primary endpoint is the change in HbA1c (%) from baseline to the end of 26 weeks. This 
endpoint will be analysed in a confirmatory way. For the primary analyses, treatment 
comparisons will be made between the randomised pooled empagliflozin (empagliflozin 10
mg and empagliflozin 25 mg, i.e. independent of patients achieving the glycaemic target at 
Week 12 and re-randomisation at Week 14) versus placebo and between the randomised 
linagliptin 5 mg versus placebo according to the initial randomisation.  The change in HbA1c 
(%) from baseline to the end of 26 weeks will be analysed using a “wash-out” approach.
7.1.2
DINAMO Mono
The primary endpoint is the occurrence of treatment failure up to or at Week 26 as a binary 
endpoint. This endpoint will be analysed in an exploratory way. The primary analysis will be 
a comparison of the treatment failure rate of linagliptin 5 mg, pooled empagliflozin and 
placebo. The risk difference of active treatments versus placebo will be determined and 
assessed by an exact 2 sided 90% confidence interval based on the method of Chan and 
Zhang [R15-1346]. Patients will be assigned to the treatment they were randomised to at the 
initial randomisation. Non-completers who prematurely discontinue intake of study drug will 
be considered treatment failures.
7.2
NULL AND ALTERNATIVE HYPOTHESES
7.2.1
DINAMO
7.2.1.1
Primary family of hypotheses
The following two hypotheses are the set of primary hypotheses in this trial.
For empagliflozin, the following null hypothesis will be tested:
H0,1: 
Mean change in HbA1c (%) from baseline to the end of 26 weeks in the pooled 
empagliflozin group
= Mean change in HbA1c (%) from baseline to the end of 26 weeks in the placebo 
group
For linagliptin, the following null hypothesis will be tested:
H0,2: 
Mean change in HbA1c (%) from baseline to the end of 26 weeks in the linagliptin 5
mg group

= Mean change in HbA1c (%) from baseline to the end of 26 weeks in the placebo 
group
The hypotheses will be tested simultaneously at the study-wise level of α = 0.05 (two-sided). 
The Hochberg-procedure will account for multiple testing within the primary family of 
hypotheses.
7.2.1.2
Secondary family of hypotheses
After having obtained statistically significant results for both hypotheses H0,1 and H0,2 of the 
primary family of hypotheses, the following two hypotheses will be tested in a hierarchical 
order at the significance level α = 0.05 (two-sided) for the comparison of empagliflozin 
versus placebo:
H’0,1: Mean change in HbA1c (%) from baseline to the end of 26 weeks in regimen starting 
on empagliflozin 10 mg and either having a dose increase to empagliflozin 25 mg in 
patients who were non-responders (i.e. patients that did not achieve HbA1c < 7.0%) at 
Week 12, or who were responders (i.e. patients that did achieve HbA1c < 7.0%) at 
Week 12 and continue with empagliflozin 10 mg
= Mean change in HbA1c (%) from baseline to the end of 26 weeks in the placebo 
group.
followed by:
H’0,2: Mean change in HbA1c (%) from baseline to the end of 26 weeks in regimen starting 
on empagliflozin 10 mg and either were responders or were non-responders at Week 
12, and continue with empagliflozin 10 mg
= Mean change in HbA1c (%) from baseline to the end of 26 weeks in the placebo 
group.
7.2.2
DINAMO Mono
It is not planned to test specific hypotheses because of the exploratory nature of DINAMOTM 
Mono.  
7.3
PLANNED ANALYSES
The statistical analysis will be based on the following populations.
Treated set
The treated set (TS) will include all patients who are treated with at least one dose of 
randomised study medication. The TS is the basis for safety analyses.

Modified intention-to-treat set
The modified intention-to-treat set (mITT) will include all randomised patients who are 
treated with at least one dose of study medication and have a baseline HbA1c measurement. 
The mITT is the basis for the primary analyses.
Per protocol set
The per protocol set (PPS) will include all patients in the mITT set who do not have any 
important protocol deviations (IPD) which can be expected to have a distorting influence on 
the assessment of the primary endpoint. Details regarding the definitions of IPDs will be 
provided in the Trial Statistical Analysis Plan (TSAP) and the decision to exclude patients 
from the PPS will be made prior to database lock.
The term “baseline” refers to the following definitions according to the individual analysis 
period.
∀
Study baseline: Last observed measurement prior to administration of any initially 
randomised study medication at Day 1.
∀
Titration baseline: Last observed measurement prior to administration of the re-
randomised study medication for the initial empagliflozin patients at Week 14.
∀
Safety baseline: Last observed measurement prior to administration of the re-
randomised study medication for the initial placebo patients at Week 26.
For analyses up to Week 26, data collected after the first intake of study medication in the 
extension period will be censored.
Analyses up to Week 12 and Week 52 will be considered exploratory in nature. The study is 
not powered to compare empagliflozin with linagliptin at Week 12, Week 26 and Week 52, 
or to compare empagliflozin 10 mg with empagliflozin 25 mg at Week 52. No hypothesis 
testing is planned, and only descriptive statistics will be provided.
The anticipation for the patients who would have taken the wrong study medication is low. 
Therefore all analyses will be based on the randomised treatments. All patients with wrong 
study medication will be listed.
For HbA1c analyses, both NGSP certified and non-NGSP certified HbA1c values will be 
used in HbA1c endpoints analyses, given that they are in the same unit. The order of 
preference for the laboratory values are: (1) NGSP certified central laboratory values, (2) 
NGSP certified local laboratory values, and (3) non-NGSP certified local laboratory values. If 
a visit window includes a NGSP certified local laboratory value as well as a non-NGSP 
certified local laboratory value (either both being on- or post-treatment), then the NGSP 
certified value will be selected rather than the non-NGSP certified value.  For study baseline, 
if none of these preference HbA1c values are available at Visit 2, then Screening data will be 
used.

The primary endpoint of DINAMOTM is defined in Section 5.1.1.
7.3.1.1.1
Analysis of the primary family of hypotheses
These confirmatory primary analyses will be performed using an effectiveness “wash-out” 
approach based on the mITT set with multiplicity adjustment for simultaneous testing of 
linagliptin and empagliflozin using the Hochberg-procedure. Patients will be assigned to the 
treatment they were randomised to at the initial randomisation, i.e. linagliptin 5 mg, pooled 
empagliflozin or placebo. HbA1c values measured after premature discontinuation of study 
drug or after rescue therapy was initiated will be included in the analyses. All available on-
and off-treatment data up to the Week 26 time point will be included.
There will be different types of missing data to be considered for the imputation.

For the placebo group, missing HbA1c data, regardless on- or off-treatment, will be imputed 
for all scheduled visits up to Week 26.
The non-monotone missing data will be imputed using Markov Chain Monte Carlo (MCMC) 
simulation and standard techniques; multiple imputation (MI) will be performed on a data set 
including on- and off-treatment HbA1c data in the placebo group at baseline, Week 4, Week 
12 and Week 26 with baseline HbA1c as a continuous covariate and age as a set of binary 
covariates corresponding to its class categorisation levels (age <15 years or age ≥15 to <18 
years). 500 imputations will be performed to ensure adequate efficiency and stability of the 
estimation for missing data. This step will be referred to as “MCMC-MI”.
For the monotone missing data, a sequential linear regression MI approach will be used and 
referred to as ‘SLR-MI’. The MI will be performed on a data set including on- and off-
treatment data and once per imputation from the previous step. This procedure will impute 
values for all missing time points both on- and off-treatment. The regression models will be 
fitted with baseline HbA1c as a continuous covariate and age as a binary covariate (age < 15 
years and age ≥15 to <18 years). 500 imputations for the placebo group will be completed.
For the active treatment groups (linagliptin 5 mg and empagliflozin pooled, regardless of the 
dose level), missing HbA1c data will be imputed for Week 26 only separately for missing on-
treatment data and missing off-treatment data. 
To impute the missing on-treatment data, the MI will be performed on a data set including 
on-treatment HbA1c data in the respective treatment group at baseline and Week 26 only.  
The regression models will be fitted separately by active treatment group with baseline 
HbA1c as a continuous covariate and age as a binary covariate (age <15 years or age ≥15 to 
<18 years). 500 imputations for each active treatment group on-treatment data will be 
completed.
To impute the missing off-treatment data, the MI will be performed on a data set including
patients with missing off-treatment HbA1c data at Week 26 in the active treatment groups 
and available on- and off-treatment HbA1c data in the placebo group at baseline and Week 
26.  The regression models will be fitted separately by active treatment group with baseline 
HbA1c as a continuous covariate and age as a binary covariate (age <15 years or age ≥15 to 
<18 years). 500 imputations for each active treatment group off-treatment data will be 
completed.
The effectiveness analyses will be performed on these imputed data sets plus the retrieved 
HbA1c data at Week 26 from the off-treatment patients, using an ANCOVA model with 
baseline HbA1c as a continuous model term, and with categorical terms for treatment and 
age. Rubin’s rules will be used to combine treatment estimates across the 500 completed
imputations.
The implicit assumption underlying the imputations and analyses is that unobserved off-
treatment patient measurements will lose any treatment effect immediately post-treatment 
discontinuation.

7.3.1.1.2
Analysis of the secondary family of hypotheses 
If the “wash-out” approach analysis for both hypotheses in the primary family of hypotheses 
shows a statistically significant result, the secondary family of hypotheses will be tested as 
ordered hypotheses at the significance level α = 0.05 (two-sided), i.e., the hypotheses H’0,1
will be tested first and if this hypothesis can be rejected at the level α = 0.05, the hypotheses 
H’0,2 will be tested at the same level.
In using two sets of hypotheses families in a hierarchical order and using all hypotheses in the 
primary family as a gatekeeper for the secondary family, the experimentwise Type I error rate 
across both families is controlled by the significance level α = 0.05.
These secondary family of hypotheses for the primary endpoint will be tested using the
“wash-out” approach described in Section 7.3.1.1 but the ANCOVA used for analysis of the 
completely imputed set will apply an “inverse probability weighting” approach based on the 
mITT set.  
The ANCOVA model will utilise a weight variable having a value of 0 for the patients who 
are not in the hypothesis test of interest; a value of 2 for re-randomised patients who are in 
the hypothesis test of interest and a value of 1 otherwise. The model terms will include 
baseline HbA1c as a continuous variable, and treatment and age as categorical variables. 
Rubin’s rules will be used to combine treatment estimates across the 500 imputations.
Patients will be assigned to the treatment they were randomised to at the initial randomisation 
together with the treatment allocation at Week 14 randomisation. HbA1c values measured 
after premature discontinuation of study drug or after rescue therapy was initiated will be 
included in the analyses. All data up to the Week 26 time point will be included.
The treatment comparisons for H’0,1 and H’0,2 according to Section 7.2.2 are as follows:
For H’0,1, this is a contrast between patients who started empagliflozin 10 mg and either 
having a dose increase in patients who were non-responder at Week 12, or who were 
responders at Week 12 and continue with empagliflozin 10 mg, and placebo.
For H’0,2, this is a contrast between patients who started empagliflozin 10 mg and either were 
responders or were non-responders at Week 12 and continue with empagliflozin 10 mg, and 
placebo.

Secondary endpoint analyses
7.3.2.1
DINAMO
Secondary endpoints of DINAMOTM are defined in Section 5.1.2.
For the secondary endpoints, the patients initially randomised to empagliflozin 
(empagliflozin 10 mg and empagliflozin 25 mg pooled) and linagliptin 5 mg will be
compared versus placebo. Analyses will be performed on the mITT set and will apply two 
approaches. 
  
The first approach will use all observed data including data after premature discontinuation 
of study drug or post rescue medication data up to Week 26.
The change in FPG from baseline to the end of 26 weeks will be analysed using an 
ANCOVA model. The statistical model will be:
FPG change from baseline to the end of 26 weeks =
overall mean + treatment + baseline FPG + age + random error
Treatment is a fixed classification effect. Baseline FPG is a linear covariate and age a 
categorical covariate. The random error is assumed to be normally distributed with mean 0 
and unknown variance σ².
The other continuous secondary endpoints will be analysed based on a restricted maximum 
likelihood (REML) approach using a mixed model for repeated measurements (MMRM). The 
analyses will include the fixed categorical effects of treatment, visit, and treatment by visit
interaction, as well as the categorical covariate age and the continuous, fixed covariates of 
baseline of the response variable and baseline of the response variable by visit interaction. 
The covariate visit will be treated as the repeated measure with an unstructured covariance 
structure used to model the within-patient measurements.
The Kenward-Roger approximation will be used to estimate denominator degrees of freedom 
and adjust standard errors. The residuals are assumed to have a multivariate normal 
distribution with zero means and covariance matrix as specified above.
The second approach will include only on-treatment values measured prior to the start of any 
rescue medication up to Week 26.
The change in FPG from baseline to the end of 26 weeks will be analysed using the 
ANCOVA model, which is described in the first approach, but using the second approach 
data.

For the other continuous secondary endpoints analyses, values measured after rescue therapy 
was initiated or after premature discontinuation of study drug will be set to missing. The 
missing data will not be imputed. The MMRM model will handle missing data based on a 
likelihood method under the "missing at random” assumption.
The proportion of patients who achieve HbA1c < 7.0% and < 6.5% at the end of 26 weeks
will be determined per treatment group and the risk difference of active treatments versus 
placebo will be determined and assessed by an exact 2-sided 95% confidence interval.
7.3.2.2
DINAMO Mono
Secondary endpoints of DINAMOTM Mono are defined in Section 5.1.2.
The secondary endpoint of time to treatment failure will be analysed and graphically 
described by Kaplan-Meier estimates up to the planned end of the study. A descriptive Log-
rank test will compare linagliptin 5 mg and pooled empagliflozin versus placebo individually
up to Week 26. Patients in the placebo group will be censored after 26 weeks unless a prior 
treatment failure is observed. Data obtained after re-randomisation in the placebo group will 
not be utilised for the determination of time to treatment failure. 
The change in HbA1c from baseline to the end of 26 weeks will be analysed based on a 
REML approach using MMRM to access the effectiveness and efficacy, using the same 
sensitivity methods as described in Section 7.3.4.1.1 and Section 7.3.4.1.3 respectively.
It is expected that a large group of drug naïve patients will require early intervention of 
rescue medication as early as first on-treatment visit, therefore the change in HbA1c from 
baseline to the end of 26 weeks will also be analysed using an ANCOVA model including 
treatment as a fixed classification effect, baseline HbA1c as a linear covariate, and age as a 
categorical covariate. The missing data will be imputed by the last on-treatment observation 
without rescue medication carried forwards. In case, there is no on-treatment observation 
without rescue medication, baseline value will be carried forward.
The following secondary endpoints will be analysed using the same methods described in 
section 7.3.2.1.
∀
Change in FPG (mg/dl) from baseline to the end of 26 weeks
∀
Change in body weight (kg) from baseline to the end of 26 weeks
∀
Change in SBP (mmHg) from baseline to the end of 26 weeks
∀
Change in DBP (mmHg) from baseline to the end of 26 weeks
The change in FPG (mg/dl) from baseline to the end of 26 weeks will also be analysed using 
an ANCOVA model including treatment as a fixed classification effect, baseline FPG as a 
linear covariate, and age as a categorical covariate. The third approach will have any post-
baseline missing values, off-treatment values and values after rescue medication imputed by 
BOCF since FPG is measured only at baseline and Week 26.

Safety analyses
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) coding dictionary. Standard BI summary tables and listings will be produced. In 
general, safety analyses will be descriptive in nature and will be based on BI standards. No 
hypothesis testing is planned.
Statistical analyses and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and end 
of the residual effect period will be considered ‘treatment-emergent’. The residual effect
period is defined as 7 days after the date of the last dose of trial medication. Adverse events 
that start before first drug intake and deteriorate under treatment will also be considered as 
‘treatment-emergent’. All AEs occurring before first study medication intake will be assigned 
to ‘pre-treatment’ and all AEs occurring after last study medication intake plus 7 days will be 
assigned to ‘post-treatment’.
Frequency, severity, and causal relationship of adverse events will be tabulated by system 
organ class and preferred term after coding according to the current version of MedDRA.
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will 
be done via comparison of laboratory data to their reference ranges. Values outside the 
reference range as well as values defined as clinically relevant will be highlighted in the 
listings. Treatment groups will be compared descriptively with regard to distribution 
parameters as well as with regard to frequency and percentage of patients with abnormal 
values or clinically relevant abnormal values.
Vital signs, physical examinations, or other safety-relevant data observed at screening, 
baseline, during the course of the trial and at the end-of-trial evaluation will be assessed with 
regard to possible changes compared to findings before start of treatment.
The safety analyses will be performed using the following population set and randomised 
study treatment combinations according to the defined period, separately for DINAMOTM and 
DINAMOTM Mono.
∀
Comparison vs. placebo: All patients in the TS will be included in the safety 
analyses up to Week 26 presented by placebo, linagliptin 5 mg and empagliflozin 
pooled.
∀
Safety during active treatment periods: All patients on active treatment at anytime 
in the TS will be included in the safety analyses up to Week 52 presented by 
linagliptin pooled and empagliflozin pooled. For patients on active treatment and 
initially randomised to placebo at the start of the study, analyses will be restricted to 
data collected after Week 26.

7.3.7
Pharmacokinetic and pharmacodynamics analyses
In order to complement the pharmacokinetic characterisations of linagliptin and 
empagliflozin in paediatric patients with T2DM, in a first step, a descriptive analysis of the 
plasma concentrations will be performed to allow for a comparison to adults. In a second 
step, a population PK analysis may be conducted if the descriptive analysis suggests 
meaningful differences in the PK of adolescents compared to adults. 
No pharmacodynamics analyses are planned.
PK analyses will be performed in the treated patients. Further information regarding the 
statistical analysis will be documented in the TSAP.
7.4
INTERIM ANALYSES
No interim analysis is planned, but the conduct of the trial will be monitored by a DMC.
7.5
HANDLING OF MISSING DATA
The handling of missing data in the primary and secondary analyses is described in Section 
7.3.1 and Section 7.3.2 respectively. 
Details regarding the imputation rule for further endpoints will be specified in the TSAP.
Missing or incomplete AE data will be imputed according to BI standards. Other missing 
safety data will not be imputed.
7.6
RANDOMISATION
At visit 2, patients will be randomised in blocks to double-blind treatment. Approximately 
equal numbers of patients will be randomised to each treatment group. The randomisation 
will be stratified by age (<15 years; ≥15 to <18 years). It will be monitored and capped so 
that at least 30% but no more than 70% of the randomised patients are < 15 years. For 
DINAMOTM only, the randomisation system will also include caps for gender so that at least 
30% but no more than 70% of the randomised patients are girls.
At visit 4B, patients from the empagliflozin 10 mg arm who do not achieve an HbA1c < 7.0% 
at Week 12 will be re-randomised in blocks to double-blind treatment with either 
empagliflozin 10 mg or empagliflozin 25 mg. This re-randomisation will be stratified by age 
at baseline (< 15 years; ≥ 15 to <18 years). Practically, an IRT call will be performed for all 
patients to maintain double-blind conditions but only patients on empagliflozin 10 mg with 
HbA1c ≥ 7.0% at Week 12 may get new trial treatment re-assigned.

At visit 5, patients from the placebo arm will be re-randomised in blocks to double-blind 
treatment. Approximately equal numbers of patients will be re-randomised to empagliflozin 
10 mg, empagliflozin 25 mg, or linagliptin 5 mg. The re-randomisation will be stratified by 
age at baseline (<15 years; ≥15 to <18 years). Practically, an IRT call will be performed for 
all patients to maintain double-blind conditions but only patients on placebo may get new 
trial treatment re-assigned.
BI will arrange for the randomisation and the packaging and labelling of trial medication. The 
randomisation list will be generated using a validated system, which involves a pseudo-
random number generator so that the resulting treatment will be both reproducible and non-
predictable. The block size will be documented in the Clinical Trial Report (CTR). Access to 
the codes will be controlled and documented. The method of assigning patients to treatment 
groups is described in Section 4.1.3.
7.7
DETERMINATION OF SAMPLE SIZE
7.7.1
DINAMO
To support the sample size determination various sample size scenarios were considered. The 
underlying assumptions and the power estimates for the final sample size are described in 
details in this section for the “wash out” effectiveness analysis. These estimates are based on 
available study data in adults with T2DM treated with placebo, linagliptin or empagliflozin. 
Sample size calculation for the “wash out” effectiveness analyses
Based on the “wash out” analysis, the superiority of pooled empagliflozin doses 
(empagliflozin 10 mg, empagliflozin 25 mg) and the superiority of linagliptin 5 mg compared 
to placebo will be tested simultaneously using the Hochberg procedure at the study-wise 
alpha level of 0.05 (see section 7.2.1).
For the corresponding power considerations post-rescue data will be included, and it will be 
assumed that there is no treatment difference for off-treatment patients. Average treatment 
effects including HbA1c values after the start of rescue therapy can be obtained from the 
studies quoted below and are summarised in Table 7.7.1: 1. The corrected treatment 
difference in this table was calculated assuming patients discontinuing active treatment show 
the same HbA1c change from baseline as the average placebo patient. 
In Table 7.7.1: 1 HbA1c results are summarised as a basis for the efficacy analysis. Where 
available data for Week 24 are quoted, otherwise for Week 18:

baseline to Week 18. For all calculations raw means and standard deviations for the primary 
endpoint were considered as initial basis for further calculations.

Based on these results a mean treatment difference in HbA1c change from baseline of -0.55% 
with a SD of 0.9% between active drugs and placebo can be assumed. For the effectiveness 
analysis a covariate adjusted standard deviation of 0.9% can be regarded as the expected 
scenario, while 0.8% will probably be optimistic. A conservative scenario of 1.0% is added 
because of the potential of increased variability through the multiple imputations performed 
for the “wash out”. Power estimates in Table 7.7.1: 2 are based on a two-sided t-test at alpha-
level of 0.05. Additionally the power is given for the alpha-level of 0.025 to provide a lower 
bound of the expected power due to the Hochberg correction for multiplicity.

Summary
The final sample size of 50 randomised patients per group was chosen as a balance of 
clinical, regulatory, ethical, feasibility and statistical considerations. The objective is to 
minimise exposure of children, given that the available paediatric population is also limited in 
number, while maintaining acceptable statistical properties.
Calculations were performed using nQuery Advisor® 7.0 statistical package by
7.7.2
DINAMO Mono
Data from the empagliflozin Phase III study 1245.20 in adult patients with Type 2 Diabetes 
were analysed to derive estimates for the treatment failure rate based on the definition in 
DINAMOTM Mono. Restricted to a study population with a baseline HbA1c from 6.5% to 
9.0% the treatment failure rates as in Table 7.7.2:1 were determined.

A treatment failure rate between 65% and 85% is expected in the placebo group in 
DINAMOTM Mono. The initial minimum sample size of 12 patients per group was chosen so 
that the upper limit of the 90% confidence interval for the risk difference would not include 0 
for an approximate risk difference of 40% (see Table 7.7.2: 2).

regulation 536/2014 and other relevant regulations.
Standard medical care (prophylactic, diagnostic and therapeutic procedures) remains in the 
responsibility of the treating physician of the patient.
The Investigator will inform the sponsor immediately of any urgent safety measures taken to 
protect the trial subjects against any immediate hazard, and also of any serious breaches of 
the protocol or of ICH GCP*.
The Boehringer Ingelheim transparency and publication policy can be found on the following 
web page: trials.boehringer-ingelheim.com. The rights of the Investigator and of the sponsor 
with regard to publication of the results of this trial are described in the Investigator contract. 
As a rule, no trial results should be published prior to finalization of the Clinical Trial 
Report.
The certificate of insurance cover is made available to the Investigator and the patients, and is 
stored in the ISF (Investigator Site File).
8.1
TRIAL APPROVAL, PATIENT INFORMATION, INFORMED CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB) / Independent Ethics Committee 
(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to patient participation in the trial, written informed consent must be obtained from one 
or both parents of the patient (or the patient’s legally accepted representative) according to 
ICH GCP and to the local regulatory and legal requirements of the participating country. 
Each signature must be personally dated by each signatory and the informed consent and any 
additional patient/parent(s)-information form retained by the investigator as part of the trial 
records. A signed copy of the informed consent and any additional parent(s) information must 
be given to each parent or the patient’s legally accepted representative. 
In addition to this document, the patient will be provided with an information sheet adapted 
to his/her age group (two groups: from 10 to 14 years; from 15 to 17 years included). The 
version prepared for the younger patient should be used for the older patient if judged more 
appropriate by the investigator) where his/her assent will be collected according to the 
regulatory and legal requirements of the participating country. Except if the patient is unable 
to do it, he/she will have to sign or write his/her name on this document and to date it in the 
day she/he assents to participate.

It is important that the investigator ensure at each visit that the patient still assents to 
participate in the study. In addition, the refusal of the patient to participate must be accepted 
independently of the consent of his/her parent(s)/legal guardian.
The patient and his/her parent(s)/legal guardian must be informed that his/her personal trial-
related data will be used by Boehringer Ingelheim in accordance with the local data 
protection law. The level of disclosure must also be explained to the patient and his/her 
parent(s)/legal guardian.
The patient and his/her parent(s)/legal guardian must be informed that the patient’s medical 
records may be examined by authorized monitors (CTM/CRA) or Clinical Quality Assurance 
auditors appointed by Boehringer Ingelheim, by appropriate IRB / IEC members, and by 
inspectors from regulatory authorities.
Re-consenting may become necessary when new relevant information becomes available and 
should be conducted according to the sponsor’s instructions. Re-consent can be done 
remotely/by telephone/telemedicine/in-home visit under exceptional circumstances due to the 
COVID-19 pandemic. The initial informed consent and assent at Visit 1A must be done in the 
clinic.
The consent and re-consenting process should be properly documented in the source 
documentation.
8.2
DATA QUALITY ASSURANCE
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial.
8.3
RECORDS
Case Report Forms (CRF) for individual patients will be provided by the sponsor. See 
Section 4.1.5.2 for rules about emergency code breaks. For drug accountability, refer to 
Section 4.1.8.
8.3.1
Source documents
In accordance with regulatory requirements the investigator should prepare and maintain 
adequate and accurate source documents and trial records that include all observations and 
other data pertinent to the investigation on each trial patient. Source data as well as reported 
data should follow good documentation practices and be attributable, legible, 
contemporaneous, original and accurate. Changes to the data should be traceable (audit trail).
Data reported on the eCRF must be consistent with the source data or the discrepancies must 
be explained. The current medical history of the patient may not be sufficient to confirm 
eligibility for the trial and the investigator may need to request previous medical histories and 
evidence of any diagnostic tests. In this case the investigator must make three documented 
attempts to retrieve previous medical records. If this fails a verbal history from the patient, 
documented in their medical records, would be acceptable.

Before providing any copy of patients’ source documents to the sponsor the investigator must 
ensure that all patient identifiers (e.g. patient’s name, initials, address, phone number, social 
security number) have properly been removed or redacted to ensure patient confidentiality.
If the patient is not compliant with the protocol, any corrective action e.g. re-training must be 
documented in the patient file. For the eCRF, data must be derived from source documents, 
for example:
∀
Patient identification: gender, date or year of birth (in accordance with local laws and 
regulations)
∀
Patient participation in the trial (substance, trial number, patient number, date patient 
and parent(s)/legal guardian was informed)
∀
Dates of patient’s visits, including dispensing of trial medication
∀
Medical history (including trial indication and concomitant diseases, if applicable)
∀
Medication history
∀
Adverse events and outcome events (onset date (mandatory), and end date (if 
available))
∀
Serious adverse events (onset date (mandatory), and end date (if available))
∀
Concomitant therapy (start date, changes)
∀
Originals or copies of laboratory results and other imaging or testing results, with 
proper documented medical evaluation (in validated electronic format, if available)
∀
Completion of “Patient’s Participation in the trial” (end date; in case of premature 
discontinuation document the reason for it).
∀
Prior to allocation of a patient to a treatment into a clinical trial, there must be 
documented evidence in the source data (e.g. medical records) that the trial participant 
meets all inclusion criteria and does not meet any exclusion criteria. The absence of 
records (either medical records, verbal documented feedback of the patient or testing 
conducted specific for a protocol) to support inclusion/exclusion criteria does not 
make the patient eligible for the clinical trial.

The sponsor will monitor the conduct of the trial by regular on-site monitoring visits and in-
house data quality review. The frequency of on-site monitoring will be determined by 
assessing all characteristics of the trial, including its nature, objective, methodology and the 
degree of any deviations of the intervention from normal clinical practice.
The investigator /institution will allow on-site trial-related monitoring, audits, IRB / IEC 
review and regulatory inspections. Direct access must be provided to the eCRF and all source 
documents/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the CRA, auditor and regulatory inspector (e.g.
FDA). The CRA and auditor may review all eCRFs and informed consents. The accuracy of 
the data will be verified by direct comparison with the source documents described in section 
8.3.1. The sponsor will also monitor compliance with the protocol and ICH GCP.
Remote source data verification in exceptional cases at the time of restricted on-site 
monitoring visits due to a COVID-19 pandemic, when such decision has been taken centrally

APPENDICES
10.1
TANNER STAGING MODIFIED
The evaluation of the Tanner stage will be performed during the physical examination at the 
time points defined in the Flow Chart to assess the patient’s pubertal stage.
To determine the Tanner stage, the investigator should perform a brief check of external 
primary and secondary sex characteristics during the physical examination. The investigator 
will then score against the scale after the child has left the examination room. The most 
advanced pubertal stage will be documented.
Age appropriate explanations will be given, with emphasis that their privacy will be respected 
at all times. They will be reassured that their research records will be anonymised and only 
authorized trusted persons will monitor their notes to ensure the research is being conducted 
properly.
Here is a representation of the Tanner staging scale for both female and male children.
