Summary of the safety profileType 2 diabetes mellitusA total of 15 582 patients with type 2 diabetes were included in clinical studies to evaluate the safetyof empagliflozin, of which 10 004 patients received empagliflozin, either alone or in combination withmetformin, a sulphonylurea, pioglitazone, DPP-4 inhibitors, or insulin.
In 6 placebo-controlled trials of 18 to 24 weeks duration, 3 534 patients were included of which 1 183were treated with placebo and 2 351 with empagliflozin. The overall incidence of adverse events inpatients treated with empagliflozin was similar to placebo. The most frequently reported adversereaction was hypoglycaemia when used with sulphonylurea or insulin (see description of selectedadverse reactions).
Heart failureThe EMPEROR studies included patients with heart failure and either reduced ejection fraction(N=3 726) or preserved ejection fraction (N=5 985) treated with empagliflozin 10 mg or placebo.
Approximately half of the patients had type 2 diabetes mellitus. The most frequent adverse reaction ofthe pooled EMPEROR-Reduced and EMPEROR-Preserved studies was volume depletion(empagliflozin 10 mg: 11.4%. placebo: 9.7%).
Chronic kidney diseaseThe EMPA-KIDNEY study included patients with chronic kidney disease (N = 6 609) treated with10 mg empagliflozin or placebo. About 44% of the patients had type 2 diabetes mellitus. The mostfrequent adverse events in the EMPA-KIDNEY study were gout (empagliflozin 7.0% vs placebo8.0%), and acute kidney injury (empagliflozin 2.8% vs placebo 3.5%) which were more frequentlyreported in patients on placebo.
The overall safety profile of empagliflozin was generally consistent across the studied indications.

Description of selected adverse reactionsHypoglycaemiaThe frequency of hypoglycaemia depended on the background therapy in the respective studies andwas similar for empagliflozin and placebo as monotherapy, add-on to metformin, add-on topioglitazone with or without metformin, as add-on to linagliptin and metformin, and as adjunct tostandard care therapy and for the combination of empagliflozin with metformin in drug-naïve patientscompared to those treated with empagliflozin and metformin as individual components. An increasedfrequency was noted when given as add-on to metformin and a sulphonylurea (empagliflozin 10 mg:
16.1%, empagliflozin 25 mg: 11.5%, placebo: 8.4%), add-on to basal insulin with or withoutmetformin and with or without a sulphonylurea (empagliflozin 10 mg: 19.5%, empagliflozin 25 mg:
28.4%, placebo: 20.6% during initial 18 weeks treatment when insulin could not be adjusted;empagliflozin 10 mg and 25 mg: 36.1%, placebo 35.3% over the 78-week trial), and add-on to MDIinsulin with or without metformin (empagliflozin 10 mg: 39.8%, empagliflozin 25 mg: 41.3%,placebo: 37.2% during initial 18 weeks treatment when insulin could not be adjusted; empagliflozin10 mg: 51.1%, empagliflozin 25 mg: 57.7%, placebo: 58% over the 52-week trial).
In the EMPEROR heart failure studies, similar frequency of hypoglycaemia was noted when used add-on to sulphonylurea or insulin (empagliflozin 10 mg: 6.5%, placebo: 6.7%).
Major hypoglycaemia (events requiring assistance)No increase in major hypoglycaemia was observed with empagliflozin compared to placebo asmonotherapy, add-on to metformin, add-on to metformin and a sulphonylurea, add-on to pioglitazonewith or without metformin, add-on to linagliptin and metformin, as adjunct to standard care therapyand for the combination of empagliflozin with metformin in drug-naïve patients compared to thosetreated with empagliflozin and metformin as individual components. An increased frequency wasnoted when given as add-on to basal insulin with or without metformin and with or without asulphonylurea (empagliflozin 10 mg: 0%, empagliflozin 25 mg: 1.3%, placebo: 0% during initial18 weeks treatment when insulin could not be adjusted; empagliflozin 10 mg: 0%, empagliflozin25 mg: 1.3%, placebo 0% over the 78-week trial), and add-on to MDI insulin with or withoutmetformin (empagliflozin 10 mg: 0.5%, empagliflozin 25 mg: 0.5%, placebo: 0.5% during initial18 weeks treatment when insulin could not be adjusted; empagliflozin 10 mg: 1.6%, empagliflozin25 mg: 0.5%, placebo: 1.6% over the 52-week trial).
In the EMPEROR heart failure studies, major hypoglycaemia was observed at similar frequencies inpatients with diabetes mellitus when treated with empagliflozin and placebo as add-on tosulphonylurea or insulin (empagliflozin 10 mg: 2.2%, placebo: 1.9%).
Vaginal moniliasis, vulvovaginitis, balanitis and other genital infectionVaginal moniliasis, vulvovaginitis, balanitis and other genital infections were reported morefrequently in patients treated with empagliflozin (empagliflozin 10 mg: 4.0%, empagliflozin 25 mg:
3.9%) compared to placebo (1.0%). These infections were reported more frequently in females treatedwith empagliflozin compared to placebo, and the difference in frequency was less pronounced inmales. The genital tract infections were mild or moderate in intensity.
In the EMPEROR heart failure studies, the frequency of these infections was more pronounced inpatients with diabetes mellitus (empagliflozin 10 mg: 2.3%; placebo: 0.8%) than in patients withoutdiabetes mellitus (empagliflozin 10 mg: 1.7%; placebo: 0.7%) when treated with empagliflozincompared to placebo.
Cases of phimosis/acquired phimosis have been reported concurrent with genital infections and insome cases, circumcision was required.
Increased urinationIncreased urination (including the predefined terms pollakiuria, polyuria, and nocturia) was observedat higher frequencies in patients treated with empagliflozin (empagliflozin 10 mg: 3.5%, empagliflozin25 mg: 3.3%) compared to placebo (1.4%). Increased urination was mostly mild or moderate inintensity. The frequency of reported nocturia was similar for placebo and empagliflozin (<1%).
In the EMPEROR heart failure studies, increased urination was observed at similar frequencies inpatients treated with empagliflozin and placebo (empagliflozin 10 mg: 0.9%, placebo 0.5%).
Urinary tract infectionThe overall frequency of urinary tract infection reported as adverse event was similar in patientstreated with empagliflozin 25 mg and placebo (7.0% and 7.2%) and higher in empagliflozin 10 mg(8.8%). Similar to placebo, urinary tract infection was reported more frequently for empagliflozin inpatients with a history of chronic or recurrent urinary tract infections. The intensity (mild, moderate,severe) of urinary tract infection was similar in patients treated with empagliflozin and placebo.
Urinary tract infection was reported more frequently in females treated with empagliflozin comparedto placebo; there was no difference in males.
Volume depletionThe overall frequency of volume depletion (including the predefined terms blood pressure(ambulatory) decreased, blood pressure systolic decreased, dehydration, hypotension, hypovolaemia,orthostatic hypotension, and syncope) was similar in patients treated with empagliflozin(empagliflozin 10 mg: 0.6%, empagliflozin 25 mg: 0.4%) and placebo (0.3%). The frequency ofvolume depletion events was increased in patients 75 years and older treated with empagliflozin 10 mg(2.3%) or empagliflozin 25 mg (4.3%) compared to placebo (2.1%).
Blood creatinine increased/Glomerular filtration rate decreasedThe overall frequency of patients with increased blood creatinine and decreased glomerular filtrationrate were similar between empagliflozin and placebo (blood creatinine increased: empagliflozin 10 mg0.6%, empagliflozin 25 mg 0.1%, placebo 0.5%; glomerular filtration rate decreased: empagliflozin10 mg 0.1%, empagliflozin 25 mg 0%, placebo 0.3%).
Initial increases in creatinine and initial decreases in estimated glomerular filtration rates in patientstreated with empagliflozin were generally transient during continuous treatment or reversible afterdrug discontinuation of treatment.
Consistently, in the EMPA-REG OUTCOME study, patients treated with empagliflozin experiencedan initial fall in eGFR (mean: 3 ml/min/1.73 m2). Thereafter, eGFR was maintained during continuedtreatment. Mean eGFR returned to baseline after treatment discontinuation suggesting acutehaemodynamic changes may play a role in these renal function changes. This phenomenon is alsoobserved in the EMPEROR heart failure studies and the EMPA-KIDNEY study.
Serum lipids increasedMean percent increases from baseline for empagliflozin 10 mg and 25 mg versus placebo,respectively, were total cholesterol 4.9% and 5.7% versus 3.5%; HDL-cholesterol 3.3% and 3.6%versus 0.4 %; LDL-cholesterol 9.5% and 10.0% versus 7.5%; triglycerides 9.2% and 9.9% versus10.5%.
Haematocrit increasedMean changes from baseline in haematocrit were 3.4% and 3.6% for empagliflozin 10 mg and 25 mg,respectively, compared to 0.1% for placebo. In the EMPA-REG Outcome study, haematocrit valuesreturned towards baseline values after a follow-up period of 30 days after treatment stop.
Paediatric populationIn the DINAMO trial 157 children aged 10 years and above with type 2 diabetes were treated, inwhich 52 patients received empagliflozin, 52 linagliptin and 53 placebo (see section 5.1).
During the placebo-controlled phase, the most frequent adverse drug reaction was hypoglycaemia withhigher overall rates for patients in the empagliflozin pooled group compared with placebo(empagliflozin 10 mg and 25 mg, pooled: 23.1%, placebo: 9.4%). None of these events was severe orrequired assistance.
Overall, the safety profile in children was similar to the safety profile in adults with type 2 diabetesmellitus.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
Pharmacotherapeutic group: Drugs used in diabetes, Sodium-glucose co-transporter 2 (SGLT2)inhibitors, ATC code: A10BK03
Mechanism of actionEmpagliflozin is a reversible, highly potent (IC50 of 1.3 nmol) and selective competitive inhibitor ofsodium-glucose co-transporter 2 (SGLT2). Empagliflozin does not inhibit other glucose transportersimportant for glucose transport into peripheral tissues and is 5 000 times more selective for SGLT2versus SGLT1, the major transporter responsible for glucose absorption in the gut. SGLT2 is highlyexpressed in the kidney, whereas expression in other tissues is absent or very low. It is responsible, asthe predominant transporter, for the reabsorption of glucose from the glomerular filtrate back into thecirculation. In patients with type 2 diabetes and hyperglycaemia a higher amount of glucose is filteredand reabsorbed.
Empagliflozin improves glycaemic control in patients with type 2 diabetes by reducing renal glucosereabsorption. The amount of glucose removed by the kidney through this glucuretic mechanism isdependent on blood glucose concentration and GFR. Inhibition of SGLT2 in patients with type 2diabetes and hyperglycaemia leads to excess glucose excretion in the urine. In addition, initiation ofempagliflozin increases excretion of sodium resulting in osmotic diuresis and reduced intravascularvolume.
In patients with type 2 diabetes, urinary glucose excretion increased immediately following the firstdose of empagliflozin and is continuous over the 24 hour dosing interval. Increased urinary glucoseexcretion was maintained at the end of the 4-week treatment period, averaging approximately78 g/day. Increased urinary glucose excretion resulted in an immediate reduction in plasma glucoselevels in patients with type 2 diabetes.
Empagliflozin improves both fasting and post-prandial plasma glucose levels. The mechanism ofaction of empagliflozin is independent of beta cell function and insulin pathway and this contributes toa low risk of hypoglycaemia. Improvement of surrogate markers of beta cell function including
Homeostasis Model Assessment-β (HOMA-β) was noted. In addition, urinary glucose excretiontriggers calorie loss, associated with body fat loss and body weight reduction. The glucosuria observedwith empagliflozin is accompanied by diuresis which may contribute to sustained and moderatereduction of blood pressure.
Empagliflozin also reduces sodium reabsorption and increases the delivery of sodium to the distaltubule. This may influence several physiological functions including, but not restricted to: increasingtubuloglomerular feedback and reducing intraglomerular pressure, lowering both pre- and afterload ofthe heart, downregulating of sympathetic activity and reducing left ventricular wall stress as evidencedby lower NT-proBNP values which may have beneficial effects on cardiac remodeling, fillingpressures and diastolic function as well as preserving kidney structure and function. Other effects suchas an increase in haematocrit, a reduction in body weight and blood pressure may further contribute tothe beneficial cardiac and renal effects.
Clinical efficacy and safetyType 2 diabetes mellitusBoth improvement of glycaemic control and reduction of cardiovascular morbidity and mortality arean integral part of the treatment of type 2 diabetes.
Glycaemic efficacy and cardiovascular outcomes have been assessed in a total of 14 663 patients withtype 2 diabetes who were treated in 12 double-blind, placebo- and active-controlled clinical studies, ofwhich 9 295 received empagliflozin (empagliflozin 10 mg: 4 165 patients; empagliflozin 25 mg: 5 130patients). Five studies had treatment durations of 24 weeks; extensions of those and other studies hadpatients exposed to empagliflozin for up to 102 weeks.
Treatment with empagliflozin as monotherapy and in combination with metformin, pioglitazone, asulphonylurea, DPP-4 inhibitors, and insulin lead to clinically relevant improvements in HbA1c,fasting plasma glucose (FPG), body weight, and systolic and diastolic blood pressure. Administrationof empagliflozin 25 mg resulted in a higher proportion of patients achieving HbA1c goal of less than7% and fewer patients needing glycaemic rescue compared to empagliflozin 10 mg and placebo.
Higher baseline HbA1c was associated with a greater reduction in HbA1c. In addition, empagliflozinas adjunct to standard care therapy reduced cardiovascular mortality in patients with type 2 diabetesand established cardiovascular disease.
MonotherapyThe efficacy and safety of empagliflozin as monotherapy was evaluated in a double-blind,placebo- and active-controlled study of 24 weeks duration in treatment-naïve patients. Treatment withempagliflozin resulted in a statistically significant (p<0.0001) reduction in HbA1c compared toplacebo (Table 2) and a clinically meaningful decrease in FPG.
In a pre-specified analysis of patients (N=201) with a baseline HbA1c ≥8.5%, treatment resulted in areduction in HbA1c from baseline of -1.44% for empagliflozin 10 mg, -1.43% for empagliflozin25 mg, -1.04% for sitagliptin, and an increase of 0.01% for placebo.
In the double-blind placebo-controlled extension of this study, reductions of HbA1c, body weight andblood pressure were sustained up to Week 76.

In a pre-specified subgroup of patients with baseline HbA1c greater or equal than 8.5% the reductionfrom baseline in HbA1c was -1.3% with empagliflozin 10 mg or 25 mg at 24 weeks (p<0.0001)compared to placebo.
Empagliflozin 24 months data, as add-on to metformin in comparison to glimepirideIn a study comparing the efficacy and safety of empagliflozin 25 mg versus glimepiride (up to 4 mgper day) in patients with inadequate glycaemic control on metformin alone, treatment withempagliflozin daily resulted in superior reduction in HbA1c (Table 6), and a clinically meaningfulreduction in FPG, compared to glimepiride. Empagliflozin daily resulted in a statistically significantreduction in body weight, systolic and diastolic blood pressure and a statistically significantly lowerproportion of patients with hypoglycaemic events compared to glimepiride (2.5% for empagliflozin,24.2% for glimepiride, p<0.0001).

Add-on to insulin therapyEmpagliflozin as add-on to multiple daily insulinThe efficacy and safety of empagliflozin as add-on to multiple daily insulin with or withoutconcomitant metformin therapy was evaluated in a double-blind, placebo-controlled trial of 52 weeksduration. During the initial 18 weeks and the last 12 weeks, the insulin dose was kept stable, but wasadjusted to achieve pre-prandial glucose levels <100 mg/dl [5.5 mmol/l], and post-prandial glucoselevels <140 mg/dl [7.8 mmol/l] between Weeks 19 and 40.
At Week 18, empagliflozin provided statistically significant improvement in HbA1c compared withplacebo (Table 7).
At Week 52, treatment with empagliflozin resulted in a statistically significant decrease in HbA1c andinsulin sparing compared with placebo and a reduction in FPG and body weight.

Cardiovascular outcomeThe double-blind, placebo-controlled EMPA-REG OUTCOME study compared pooled doses ofempagliflozin 10 mg and 25 mg with placebo as adjunct to standard care therapy in patients withtype 2 diabetes and established cardiovascular disease. A total of 7 020 patients were treated(empagliflozin 10 mg: 2 345, empagliflozin 25 mg: 2 342, placebo: 2 333) and followed for a medianof 3.1 years. The mean age was 63 years, the mean HbA1c was 8.1%, and 71.5% were male. Atbaseline, 74% of patients were being treated with metformin, 48% with insulin, and 43% with asulphonylurea. About half of the patients (52.2%) had an eGFR of 60-90 ml/min/1.73 m2, 17.8% of45-60 ml/min/1.73 m2 and 7.7% of 30-45 ml/min/1.73 m2.
At week 12, an adjusted mean (SE) improvement in HbA1c when compared to baseline of 0.11%(0.02) in the placebo group, 0.65% (0.02) and 0.71% (0.02) in the empagliflozin 10 and 25 mg groupswas observed. After the first 12 weeks glycaemic control was optimized independent of investigativetreatment. Therefore the effect was attenuated at week 94, with an adjusted mean (SE) improvement in
HbA1c of 0.08% (0.02) in the placebo group, 0.50% (0.02) and 0.55% (0.02) in the empagliflozin10 and 25 mg groups.
Empagliflozin was superior in preventing the primary combined endpoint of cardiovascular death,non-fatal myocardial infarction, or non-fatal stroke, as compared with placebo. The treatment effectwas driven by a significant reduction in cardiovascular death with no significant change in non-fatalmyocardial infarction, or non-fatal stroke. The reduction of cardiovascular death was comparable forempagliflozin 10 mg and 25 mg (Figure 1) and confirmed by an improved overall survival (Table 10).
The effect of empagliflozin on the primary combined endpoint of CV death, non-fatal MI, or non-fatalstroke was largely independent of glycaemic control or renal function (eGFR) and generally consistentacross eGFR categories down to an eGFR of 30 ml/min/1.73 m2 in the EMPA-REG OUTCOMEstudy.
The efficacy for preventing cardiovascular mortality has not been conclusively established in patientsusing empagliflozin concomitantly with DPP-4 inhibitors or in Black patients because therepresentation of these groups in the EMPA-REG OUTCOME study was limited.

Heart failure requiring hospitalisation
In the EMPA-REG OUTCOME study, empagliflozin reduced the risk of heart failure requiringhospitalisation compared with placebo (empagliflozin 2.7 %; placebo 4.1 %; HR 0.65, 95 % CI 0.50,0.85).
NephropathyIn the EMPA-REG OUTCOME study, for time to first nephropathy event, the HR was 0.61 (95 % CI0.53, 0.70) for empagliflozin (12.7 %) vs placebo (18.8 %).
In addition, empagliflozin showed a higher (HR 1.82, 95 % CI 1.40, 2.37) occurrence of sustainednormo- or micro-albuminuria (49.7 %) in patients with baseline macro-albuminuria compared withplacebo (28.8 %).
Fasting plasma glucoseIn four placebo-controlled studies, treatment with empagliflozin as monotherapy or add-on therapy tometformin, pioglitazone, or metformin plus a sulphonylurea resulted in mean changes from baseline in
FPG of -20.5 mg/dl [-1.14 mmol/l] for empagliflozin 10 mg and -23.2 mg/dl [-1.29 mmol/l] forempagliflozin 25 mg compared to placebo (7.4 mg/dl [0.41 mmol/l]). This effect was observed after24 weeks and maintained for 76 weeks.
2-hour post-prandial glucoseTreatment with empagliflozin as add-on to metformin or metformin and a sulphonylurea resulted in aclinically meaningful reduction of 2-hour post-prandial glucose (meal tolerance test) at 24 weeks(add-on to metformin: placebo +5.9 mg/dl, empagliflozin 10 mg: -46.0 mg/dl, empagliflozin25 mg: -44.6 mg/dl, add-on to metformin and a sulphonylurea: placebo -2.3 mg/dl, empagliflozin10 mg: -35.7 mg/dl, empagliflozin 25 mg: -36.6 mg/dl).
Patients with high baseline HbA1c >10%
In a pre-specified pooled analysis of three phase 3 studies, treatment with open-label empagliflozin25 mg in patients with severe hyperglycaemia (N=184, mean baseline HbA1c 11.15%) resulted in aclinically meaningful reduction in HbA1c from baseline of 3.27% at week 24; no placebo orempagliflozin 10 mg arms were included in these studies.
Body weightIn a pre-specified pooled analysis of 4 placebo-controlled studies, treatment with empagliflozinresulted in body weight reduction (-0.24 kg for placebo, -2.04 kg for empagliflozin 10 mgand -2.26 kg for empagliflozin 25 mg) at week 24 that was maintained up to week 52 (-0.16 kg forplacebo, -1.96 kg for empagliflozin 10 mg and -2.25 kg for empagliflozin 25 mg).
Blood pressureThe efficacy and safety of empagliflozin was evaluated in a double-blind, placebo-controlled study of12 weeks duration in patients with type 2 diabetes and high blood pressure on different antidiabeticand up to 2 antihypertensive therapies. Treatment with empagliflozin once daily resulted instatistically significant improvement in HbA1c, and 24 hour mean systolic and diastolic blood pressureas determined by ambulatory blood pressure monitoring (Table 11). Treatment with empagliflozinprovided reductions in seated SBP and DBP.

In a pre-specified pooled analysis of 4 placebo-controlled studies, treatment with empagliflozinresulted in a reduction in systolic blood pressure (empagliflozin 10 mg: -3.9 mmHg; empagliflozin25 mg: -4.3 mmHg) compared with placebo (-0.5 mmHg) and in diastolic blood pressure(empagliflozin 10 mg: -1.8 mmHg; empagliflozin 25 mg: -2.0 mmHg) compared with placebo(-0.5 mmHg) at week 24 that were maintained up to week 52.
Heart failureEmpagliflozin in patients with heart failure and reduced ejection fractionA randomised, double-blind, placebo-controlled study (EMPEROR-Reduced) was conducted in 3 730patients with chronic heart failure (New York Heart Association [NYHA] II-IV) and reduced ejectionfraction (LVEF ≤40%) to evaluate the efficacy and safety of empagliflozin 10 mg once daily asadjunct to standard of care heart failure therapy. The primary endpoint was the time to adjudicatedfirst event of either cardiovascular (CV) death or hospitalisation for heart failure (HHF). Occurrenceof adjudicated HHF (first and recurrent) and eGFR (CKD-EPI)cr slope of change from baseline wereincluded in the confirmatory testing. Heart Failure therapy at baseline included ACEinhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitor (88.3%), betablockers (94.7%), mineralocorticoid receptor antagonists (71.3%) and diuretics (95.0%).
A total of 1 863 patients were randomised to empagliflozin 10 mg (placebo: 1 867) and followed for amedian of 15.7 months. The study population consisted of 76.1% men and 23.9% women with a meanage of 66.8 years (range: 25-94 years), 26.8% were 75 years of age or older. 70.5% of the studypopulation were White, 18.0% Asian and 6.9% Black/African American. At randomisation, 75.1% ofpatients were NYHA class II, 24.4% were class III and 0.5% were class IV. The mean LVEF was27.5%. At baseline, the mean eGFR was 62.0 ml/min/1.73 m2 and the median urinary albumin tocreatinine ratio (UACR) was 22 mg/g. About half of the patients (51.7%) had an eGFR of≥60 ml/min/1.73 m2, 24.1% of 45 to <60 ml/min/1.73 m2, 18.6% of 30 to <45 ml/min/1.73 m2 and5.3% 20 to <30 ml/min/1.73 m2.
Empagliflozin was superior in reducing the risk of the primary composite endpoint of cardiovasculardeath or hospitalisation for heart failure compared with placebo. Additionally, empagliflozinsignificantly reduced the risk of occurrence of HHF (first and recurrent), and significantly reduced therate of eGFR decline (Table 12; Figure 2).

The results of the primary composite endpoint were generally consistent with a hazard ratio (HR)below 1 across the pre-specified subgroups, including patients with heart failure, with or without type2 diabetes mellitus and with or without renal impairment (down to an eGFR of 20 ml/min/1.73 m2).
Empagliflozin in patients with heart failure and preserved ejection fractionA randomised, double-blind, placebo-controlled study (EMPEROR-Preserved) was conducted in5 988 patients with chronic heart failure (NYHA II-IV) and preserved ejection fraction (LVEF >40%)to evaluate the efficacy and safety of empagliflozin 10 mg once daily as adjunct to standard of caretherapy. The primary endpoint was the time to adjudicated first event of either cardiovascular (CV)death or hospitalisation for heart failure (HHF). Occurrence of adjudicated HHF (first and recurrent),and eGFR (CKD-EPI)cr slope of change from baseline were included in the confirmatory testing.
Baseline therapy included ACE inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitor (80.7%), beta blockers (86.3%), mineralocorticoid receptor antagonists (37.5%)and diuretics (86.2%).
A total of 2 997 patients were randomised to empagliflozin 10 mg (placebo: 2 991) and followed for amedian of 26.2 months. The study population consisted of 55.3% men and 44.7% women with a meanage of 71.9 years (range: 22-100 years), 43.0% were 75 years of age or older. 75.9% of the studypopulation were White, 13.8% Asian and 4.3% Black/African American. At randomisation, 81.5% ofpatients were NYHA class II, 18.1% were class III and 0.3% were class IV. The EMPEROR-
Preserved study population included patients with a LVEF <50% (33.1%), with a LVEF 50 to <60%(34.4%) and a LVEF ≥60% (32.5%). At baseline, the mean eGFR was 60.6 ml/min/1.73 m2 and themedian urinary albumin to creatinine ratio (UACR) was 21 mg/g. About half of the patients (50.1%)had an eGFR of ≥60 ml/min/1.73 m2, 26.1% of 45 to <60 ml/min/1.73 m2, 18.6% of 30 to <45ml/min/1.73 m2 and 4.9% 20 to <30 ml/min/1.73 m2.
Empagliflozin was superior in reducing the risk of the primary composite endpoint of cardiovasculardeath or hospitalisation for heart failure compared with placebo. Additionally, empagliflozinsignificantly reduced the risk of occurrence of HHF (first and recurrent), and significantly reduced therate of eGFR decline (Table 13; Figure 3).

The results of the primary composite endpoint were consistent across each of the pre-specifiedsubgroups categorized by e.g., LVEF, diabetes status or renal function (down to an eGFR of20 ml/min/1.73 m2).
Chronic kidney diseaseA randomised, double-blind, placebo-controlled study of empagliflozin 10 mg once daily (EMPA-
KIDNEY) was conducted in 6 609 patients with chronic kidney disease (eGFR ≥20 -<45 ml/min/1.73 m2; or eGFR ≥45 - <90 ml/min/1.73 m2 with urinary albumin to creatinine ratio(UACR) ≥200 mg/g) to assess cardio-renal outcomes as adjunct to standard of care therapy. Theprimary endpoint was the time to first occurrence of kidney disease progression (sustained ≥40%eGFR decline from randomisation, sustained eGFR <10 ml/min/1.73 m², end-stage kidney disease, orrenal death) or CV death. First occurrence of hospitalisation for heart failure or CV death, all-causehospitalisation (first and recurrent), and all-cause mortality were included in the confirmatory testing.
Baseline therapy included an appropriate use of a RAS-inhibitor (85.2% ACE inhibitor or angiotensinreceptor blocker).
A total of 3 304 patients were randomised to empagliflozin 10 mg (placebo: 3 305) and followed for amedian of 24.3 months. The study population consisted of 66.8% men and 33.2% women with a meanage of 63.3 years (range: 18-94 years), 23.0% were 75 years of age or older. 58.4% of the studypopulation were White, 36.2% Asian and 4.0% Black/African American.
At baseline, the mean eGFR was 37.3 ml/min/1.73 m2, 21.2% patients had an eGFR of≥45 ml/min/1.73 m2, 44.3% of 30 to <45 ml/min/1.73 m2 and 34.5% <30 ml/min/1.73 m2 including254 patients with an eGFR <20 ml/min /1.73 m2. The median UACR was 329 mg/g, 20.1% patientshad an UACR <30 mg/g, 28.2% had an UACR 30 to ≤300 mg/g and 51.7% had an UACR >300 mg/g;41.1% of patients had an UACR <200 mg/g. Primary causes of CKD were diabeticnephropathy/diabetic kidney disease (31%), glomerular disease (25%), hypertensive/renovasculardisease (22%) and other/unknown (22%).
Empagliflozin was superior in reducing the risk of the primary composite endpoint of kidney diseaseprogression or CV death compared with placebo (see Table 14). Additionally, empagliflozinsignificantly reduced the risk of all-cause hospitalisation (first and recurrent).

The results of the primary composite endpoint were generally consistent across the pre-specifiedsubgroups, including eGFR categories, underlying cause of renal disease, diabetes status, orbackground use of RAS inhibitors. Treatment benefits were more clearly evident in patients withhigher levels of albuminuria.
During treatment, eGFR decline over time was slower in the empagliflozin group compared to theplacebo group (Figure 5). Empagliflozin slowed the annual rate of eGFR decline compared to placeboby 1.37 ml/min/1.73 m2/year (95% CI 1.16, 1.59), based on a pre-specified analysis of all eGFRmeasurements taken from the 2-month visit to the final follow-up visit. Patients treated withempagliflozin experienced an initial drop in eGFR which returned towards baseline after treatmentdiscontinuation as demonstrated in several of the empagliflozin studies, supporting thathaemodynamic changes play a role in the acute effects of empagliflozin on eGFR.

Paediatric populationType 2 diabetes mellitusThe clinical efficacy and safety of empagliflozin (10 mg with a possible dose-increase to 25 mg) andlinagliptin (5 mg) once daily has been studied in children and adolescents from 10 to 17 years of agewith type 2 diabetes mellitus in a placebo-controlled study (DINAMO) over 26 weeks, with a safetyextension period up to 52 weeks. Background therapies as adjunct to diet and exercise includedmetformin (51%), a combination of metformin and insulin (40.1%), insulin (3.2%), or none (5.7%).
The adjusted mean change in HbA1c at week 26 between empagliflozin (N=52) and placebo (N=53)of -0.84% was clinically meaningful and statistically significant (95% CI -1.50, -0.19; p=0.0116). Inaddition, treatment with empagliflozin versus placebo resulted in a clinically meaningful adjustedmean change in FPG of -35.2 mg/dl (95% CI -58.6, -11.7) [-1.95 mmol/l (-3.25, -0.65)].
