RESUMEN
AIMS: To apply the diabetes staging system (DSS), a novel disease staging system similar to what is used in oncology but designed to improve diabetes management, to three large type 2 diabetes (T2D) cardiovascular (CV) outcome trials to assess whether increasing DSS stage was associated with higher rates of all-cause mortality (ACM) and/or CV death. MATERIALS AND METHODS: The DSS uses discrete CV events (none to ≥3: Stage 1 to 4), end-stage kidney disease (Stage 5) and microvascular complications (none to 3: A to D) to determine disease stage in individuals with T2D. The DSS stage for patients from the CAROLINA, EMPA-REG OUTCOME and CARMELINA trials was determined. Incidence rates for ACM/CV death were calculated across DSS stages and Cox regression analyses were performed. RESULTS: The risk of ACM or CV death increased with increasing DSS (Stage 1 to 5; P for trend <0.0001) in all trials. In CAROLINA, the risk of ACM and CV death increased with increasing number of microvascular complications (A to D; both P for trend <0.0001), similar in CARMELINA (P for trend = 0.0020 and 0.0005, respectively). In EMPA-REG OUTCOME, having all three microvascular complications (Stage D), versus none, increased the risk of ACM and CV death (P = 0.0015 and 0.0010, respectively). CONCLUSIONS: Applying the DSS across T2D clinical trial populations with different CV risk revealed a significantly increased risk of ACM and CV death with higher DSS stage. The DSS may merit assessment in other T2D populations and evaluation of the impact of additional outcomes, such as heart failure, could also be worthwhile.

BACKGROUND: Patients with type 2 diabetes and atherosclerotic cardiovascular disease are at high clinical risk. We assessed the effect of the sodium-glucose co-transporter-2 inhibitor, empagliflozin, on total cardiovascular events and admissions to hospital in the EMPA-REG OUTCOME trial. METHODS: The EMPA-REG OUTCOME trial was a randomised, double-blind, non-inferiority trial of patients (aged ≥18 years) with type 2 diabetes and atherosclerotic cardiovascular disease done between August, 2010, and April, 2015. Participants were randomly assigned (1:1:1) to empagliflozin 10 mg or 25 mg, or placebo. The primary outcome was major adverse cardiovascular events: a composite of cardiovascular death, non-fatal stroke, or non-fatal myocardial infarction. As prespecified, the effects of pooled empagliflozin versus placebo were assessed on total (first plus recurrent) events of major adverse cardiovascular events, fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, and admission to hospital for heart failure. We also did post-hoc analyses on additional cardiovascular and admission to hospital outcomes. We used statistical models that preserve randomisation and account for correlation of recurrent events, including negative binomial regression, as prespecified for the primary analyses. The EMPA-REG OUTCOME trial is registered with ClinicalTrials.gov, NCT01131676, and is closed to accrual. FINDINGS: In the EMPA-REG OUTCOME trial, 7020 patients were randomly assigned and treated with empagliflozin 10 mg (n=2345), empagliflozin 25 mg (n=2342), or placebo (n=2333) and followed up for a median of 3·2 years (IQR 2·2 to 3·6) in the pooled empagliflozin group and 3·1 years (2·2 to 3·5) in the placebo group. Analysing total (first plus recurrent) events, empagliflozin versus placebo reduced the risk of major adverse cardiovascular events (rate ratio [RR] 0·78 [95% CI 0·67 to 0·91]; p=0·0020; 12·88 [95% CI 3·74 to 22·02] events prevented per 1000 patient-years); fatal or non-fatal myocardial infarction (0·79 [0·62 to 0·998]; p=0·049; 4·97 [-0·68 to 10·61] events prevented per 1000 patient-years); the composite of fatal or non-fatal myocardial infarction, or coronary revascularisation (0·80 [0·67 to 0·95]; p=0·012; 11·65 [1·25 to 22·05] events prevented per 1000 patient-years); admission to hospital for heart failure (0·58 [0·42 to 0·81]; p=0·0012; 9·67 [3·07 to 16·28] events prevented per 1000 patient-years); and all-cause admission to hospital (0·83 [0·76 to 0·91]; p<0·0001; 50·41 [26·20 to 74·63] events prevented per 1000 patient-years). For outcomes significantly reduced with empagliflozin, risk reductions were numerically larger for total events than for first events. Total fatal or non-fatal stroke was not significantly different between treatment groups (RR 1·10 [95% CI 0·82 to 1·49]; p=0·52). INTERPRETATION: Empagliflozin reduced the total burden of cardiovascular complications and all-cause admission to hospital in patients with type 2 diabetes and atherosclerotic cardiovascular disease.

BACKGROUND: Glucose variability has been associated with cardiovascular outcomes in type 2 diabetes, however, the interplay between glucose variability, empagliflozin and cardiovascular death has not been explored. In the EMPA-REG OUTCOME trial, empagliflozin reduced the risk of cardiovascular death by 38%. We explore post-hoc the association between HbA1c variability and cardiovascular death, and the potential mediating effects of HbA1c variability on empagliflozin's cardiovascular death reductions. METHODS: In total, 7,020 patients with type 2 diabetes and established cardiovascular disease received placebo, empagliflozin 10 mg or 25 mg. We defined within-patient HbA1c variability as standard deviation, coefficient of variation and range of HbA1c measurements (%) post-baseline. First, we compared HbA1c variability until week 28 and 52 by Wilcoxon tests. We explored the association between cardiovascular death and HbA1c variability in placebo and pooled empagliflozin arms separately with landmark analyses at week 28 and 52, and additionally with HbA1c variability as a time-dependent co-variate. We used Cox regression models adjusted for baseline risk factors including changes in HbA1c from baseline to week 12, and the interaction term HbA1c variability* treatment. RESULTS: HbA1c variability was lower with empagliflozin compared to placebo. In all Cox analyses, high HbA1c variability increased the risk for cardiovascular death in both treatment arms with no interaction with treatment: e.g. an increase in HbA1c variability of one unit for the standard deviation at week 28 was associated with a subsequent increased risk of CV death with HRs of 1.97 (95% CI 1.36, 2.84) and 1.53 (1.01, 2.31) in the placebo and empagliflozin groups, separately, interaction p-value 0.3615. CONCLUSIONS: HbA1c variability was reduced by empagliflozin and high values of HbA1c variability were associated with an increased risk of cardiovascular death. Empagliflozin's reduction in cardiovascular death did not appear to be mediated by reductions in HbA1c variability. ClinicalTrials.gov number, NCT01131676.

AIMS: Heart failure (HF) and type 2 diabetes (T2D), common co-morbidities, translate into worse patient prognoses and higher direct costs than for either condition alone. Empagliflozin has been shown to markedly reduce cardiovascular (CV) deaths and HF hospitalizations (HHF) in HF patients with T2D. This study evaluated the lifetime cost-effectiveness of supplementing standard of care (SoC) with empagliflozin, relative to SoC alone, in HF patients with T2D from the UK payer perspective. METHODS AND RESULTS: An existing discrete-event simulation model was adapted for the economic evaluation. Risk equations developed from time-dependent parametric survival analyses using patient-level HF subpopulation data from the EMPA-REG OUTCOME trial were employed to predict CV and renal events. Non-CV death, utility weights, and costs were drawn from UK sources. Quality-adjusted life years (QALYs) and costs were discounted at 3.5% per annum. Relative to SoC, empagliflozin with SoC yielded fewer first HHF, recurrent HHF, CV death, and non-fatal myocardial infarction but more non-fatal stroke events. Empagliflozin with SoC vs. SoC alone was associated with increased average life expectancy (10.80 vs. 9.59 LYs) and quality of life (6.27 vs. 5.62 QALYs), though at higher lifetime cost (£18 197 vs. £16 829) per person, resulting in an incremental cost-effectiveness ratio of £2093 per QALY. The probability of empagliflozin being cost-effective in the HF subpopulation at a £20 000 per QALY willingness-to-pay threshold was 91%. CONCLUSIONS: This analysis suggests that adding empagliflozin to SoC in HF patients with T2D constitutes a cost-effective use of UK healthcare resources and may provide long-term health benefits to patients.
RESUMEN
BACKGROUND: The sodium-glucose co-transporter 2 (SGLT2) inhibitor empagliflozin reduced cardiovascular death or heart failure hospitalizations in type 2 diabetes (T2D) in addition to a reduction of SBP. As heart failure patients often present with low SBP, which can challenge treatment initiation, we explored if empagliflozin's effect on SBP was independent of baseline SBP and heart failure status, and if the effect on cardiovascular and heart failure outcomes was influenced by updated mean SBP or by an early change in SBP after drug initiation. METHODS AND RESULTS: A total of 7020 patients were treated with empagliflozin 10âmg, 25âmg or placebo and followed for a median of 3.1 years. All of them had BP measurement at baseline. We evaluated changes in SBP in the context of heart failure status at baseline and according to baseline SBP categories (<120, 120--<130, 130--<140, 140--<160, ≥160âmmHg). The updated mean SBP during the trial was calculated as a time-dependent variable. We then assessed the association of baseline and updated mean SBP with three-point major adverse cardiovascular events (3P-MACE), hospitalization for heart failure, cardiovascular death, hospitalization for heart failure or cardiovascular death, all-cause death, and incident/worsening nephropathy, and whether treatment effect of empagliflozin vs. placebo on these outcomes differed if adjusted for updated mean SBP. Finally, we evaluated the impact of early decline in SBP (≥5âmmHg at week 4) on the treatment effect of empagliflozin vs. placebo on these outcomes. Analyses were performed via Cox regression adjusting for baseline risk factors including a term for treatment subgroup interaction, and by landmark analyses starting at week 4. The difference in SBP reduction at week 12 between empagliflozin and placebo was 3--5âmmHg and similar regardless of baseline SBP category or HF status at baseline. Baseline SBP and updated mean SBP categories showed no association with cardiovascular outcomes, but was associated with new/worsening nephropathy. The treatment effects of empagliflozin on all explored outcomes were independent of updated mean SBP as well of the early drop in SBP on treatment. CONCLUSION: In addition to decreasing SBP, empagliflozin reduced cardiovascular, heart failure and renal outcomes independently of updated mean SBP during the trial, and of the early SBP drop. These results suggest a BP-independent effect of empagliflozin on cardiovascular and heart failure outcomes. CLINICALTRIALS. GOV IDENTIFIER: NCT01131676.

INTRODUCTION: The aim of this analysis was to characterize the safety and tolerability of empagliflozin in patients with type 2 diabetes mellitus (T2DM) who were randomized to empagliflozin (10/25 mg) or placebo in clinical trials. METHODS: Pooled data from 20 trials were analyzed for patients with T2DM treated with empagliflozin 10 mg (n = 4858), empagliflozin 25 mg (n = 5057), or placebo (n = 4904). The dataset comprised 15 randomized phase I-III trials, an extension trial and dose escalation studies. Adverse events (AEs) were assessed descriptively in participants who took ≥ 1 dose of study drug. AE incidence rates per 100 patient-years were calculated to adjust for differences in drug exposure between trials. RESULTS: Total exposure was 16,480 and 7857 patient-years in the pooled empagliflozin 10/25 mg and placebo groups, respectively. The incidence of any AEs, AEs leading to treatment discontinuation, severe AEs, and serious AEs was similar across groups. The frequency of serious AEs requiring hospitalization was 18.6% for the empagliflozin 10/25 mg group and 21.3% for the placebo group. The empagliflozin 10/25 mg group was not associated with a higher rate of confirmed hypoglycemia versus placebo, except in patients co-administered insulin and/or a sulfonylurea (31.5% vs. 30.2%, respectively). The incidence of events consistent with urinary tract infections (UTI) was also similar for the empagliflozin 10/25 mg group versus placebo (9.27 vs. 9.70/100 patient-years, respectively). History of UTI was identified as a risk factor for UTI during treatment. Events consistent with genital infections occurred more frequently with empagliflozin 10/25 mg than placebo (3.54 vs. 0.95/100 patient-years, respectively). The frequency of AEs consistent with volume depletion was similar across groups, but higher with empagliflozin 10/25 mg than placebo in patients aged 75 to < 85 years and those on loop diuretics at baseline. CONCLUSION: This comprehensive analysis confirms that both empagliflozin 10 mg and 25 mg are well tolerated in patients with T2DM, reinforcing the established clinical safety profile of empagliflozin.
Empagliflozin is approved to treat adults with type 2 diabetes mellitus (T2DM) insufficiently controlled by diet and exercise. It lowers blood glucose levels by inhibiting sodium-glucose co-transporter-2 (SGLT2), a protein involved in glucose reabsorption by the kidneys. By blocking SGLT2, glucose is removed in urine instead of being reabsorbed into the bloodstream. Numerous clinical studies have shown the effectiveness and safety of empagliflozin, but recent reports of two types of serious side effects [fractures and lower limb amputations (LLAs)] associated with another drug in the class, canagliflozin, has triggered a review of the risk associated with taking SGLT2 inhibitors. To examine the safety and tolerability of empagliflozin we pooled data from 20 clinical trials involving over 15,000 patients with T2DM who received either empagliflozin or placebo (control). We found that the risk of side effects was similar whether patients received empagliflozin or placebo. This included side effects that led to treatment being stopped as well as severe and serious side effects, including fractures and LLAs. Empagliflozin was not associated with a higher rate of hypoglycemia (low blood sugar) versus placebo, except in patients also treated with insulin and/or a sulfonylurea (31.5% vs. 30.2%, respectively). The risk of urinary tract infections was also similar for empagliflozin versus placebo (9.27 vs. 9.70/100 patient-years, respectively). However, genital infections, as anticipated, occurred more frequently in patients treated with empagliflozin than placebo (3.54 vs. 0.95/100 patient-years, respectively). Overall, this analysis confirms the results of previous studies showing that empagliflozin is well tolerated in patients with T2DM.

AIMS: In the EMPA-REG OUTCOME® trial, the sodium-glucose cotransporter 2 inhibitor empagliflozin when given in addition to standard care improved cardiovascular (CV) and renal outcomes, and reduced mortality. Trial participants were on a variety of glucose-lowering therapies at baseline, some of which could potentially affect CV risk. This analysis investigated whether the use of background diabetes therapy affected the risk of CV death, hospitalizations for heart failure, and progression of chronic kidney disease, among patients treated with empagliflozin. MATERIALS AND METHODS: Patients meeting inclusion and exclusion criteria were randomized to placebo, empagliflozin 10 mg or empagliflozin 25 mg; glucose-lowering therapy was to remain unchanged for 12 weeks and then adjusted to achieve glycaemic control according to local guidelines. Differences in risk of cardio-renal outcomes between empagliflozin and placebo by baseline use of metformin, sulphonylurea (SU) and insulin were assessed using a Cox proportional hazards model. RESULTS: Of 7020 eligible patients, 74% were receiving metformin, 43% SU and 48% insulin at baseline (each alone or in combination); the most common regimens were metformin plus SU (20%) and metformin plus insulin (20%). Empagliflozin reduced the risk of CV death irrespective of the use of: metformin [with: hazard ratio (HR) 0.71 (95% confidence interval, CI, 0.54-0.94); without: 0.46 (0.32-0.68); Pinteraction = 0.07]; SU [with: HR 0.64 (0.44-0.92); without: 0.61 (0.46-0.81); Pinteraction = 0.85]; or insulin [with: HR 0.63 (0.46-0.85); without: 0.61 (0.44-0.85); Pinteraction = 0.92]. Reductions in three-point major adverse CV events, hospitalizations for heart failure, and all-cause mortality were consistent across subgroups of baseline therapies. Empagliflozin reduced the risks of incident or worsening nephropathy versus placebo irrespective of the use of SU or insulin at baseline (Pinteraction > 0.05), but there was a greater reduction in this risk for patients not using metformin [HR 0.47 (95% CI 0.37-0.59)] versus those using metformin [HR 0.68 (95% CI 0.58-0.79)] at baseline (Pinteraction = 0.01). CONCLUSIONS: The addition of empagliflozin to antihyperglycaemic regimens of patients with type 2 diabetes and CV disease consistently reduced their risks of adverse CV outcomes and mortality irrespective of baseline use of metformin, SU or insulin. For chronic kidney disease progression, there may be a larger benefit from empagliflozin in those patients who are not using metformin.

OBJECTIVE: The risks of cardio-renal complications of diabetes increase with age. In the EMPA-REG OUTCOME® trial, empagliflozin reduced cardiovascular (CV) mortality by 38% in patients with type 2 diabetes (T2D) and CV disease. Here we compare outcomes with empagliflozin in older patients in EMPA-REG OUTCOME. METHODS: Patients with T2D and CV disease were randomised to empagliflozin 10 or 25 mg, or placebo plus standard of care. In post hoc analyses, risks of 3-point major adverse CV events (3P-MACE: composite of CV death, non-fatal myocardial infarction (MI) or non-fatal stroke), CV death, hospitalisation for heart failure, all-cause mortality, all-cause hospitalisation and incident/worsening nephropathy were evaluated for empagliflozin versus placebo by baseline age (<65, 65 to <75, ≥75 years). Adverse events (AEs) were analysed descriptively. RESULTS: Effect of empagliflozin on all outcomes was consistent across age categories (P ≥ 0.05 for interactions) except 3P-MACE. The 3P-MACE hazard ratios (HRs) were 1.04 (95% confidence interval [CI] 0.84, 1.29), 0.74 (0.58, 0.93) and 0.68 (0.46, 1.00) in patients aged <65, 65 to <75, and ≥75 years, respectively (P = 0.047 for treatment-by-age group interaction). Corresponding CV death HRs were 0.72 (95% CI 0.52, 1.01), 0.54 (0.37, 0.79) and 0.55 (0.32, 0.94), respectively (P = 0.484 for treatment-by-age group interaction). Across age categories, empagliflozin AEs reflected its known safety profile. Rates of bone fractures, renal AEs and diabetic ketoacidosis were similar between empagliflozin and placebo across age categories. CONCLUSIONS: In the EMPA-REG OUTCOME trial, empagliflozin reduced risks of CV mortality, heart failure and renal outcomes, supporting its cardio-renal benefits in older patients.

PURPOSE: The goal of this study was to assess the cost-effectiveness of empagliflozin in Japan based on the Asian subpopulation in the EMPA-REG OUTCOME trial. METHODS: The trial has shown a reduction in the risk for cardiovascular (CV) and renal events with empagliflozin in patients with type 2 diabetes mellitus and established CV disease. A cost-effectiveness analysis based on the overall population of the EMPA-REG OUTCOME trial was reported previously by using a lifetime discrete event simulation model. The same modeling frame was adapted to evaluate the cost-effectiveness of treatment with empagliflozin added to standard of care (SoC) compared with SoC alone in Japan. The time to relevant clinical events and the hazard ratios were derived from an Asian subpopulation in the EMPA-REG OUTCOME trial. The costs for each event were estimated from a Japanese medical claims database. Direct medical costs, life expectancy, and quality-adjusted life years (QALYs) were calculated from the public health care perspective. FINDINGS: Treatment with empagliflozin was estimated to increase life expectancy by 6.2 years and 2.7 QALYs, whereas total cost increased by 1,115,475 yen compared with treatment with SoC alone. The incremental cost-effectiveness ratio was 415,849 yen/QALY. In the sensitivity analysis, there was no case that was in excess of the reference value of the incremental cost-effectiveness ratio in the pilot introduction for price revision in Japan (ie, 5 million yen/QALY). IMPLICATIONS: Based on the Asian subpopulation in the EMPA-REG OUTCOME trial, our results suggest that empagliflozin added to SoC is highly cost-effective compared with SoC alone in Japan.

INTRODUCTION: We report a randomized, double-blind, placebo-controlled, 4-week study to investigate the effect of empagliflozin on free fatty acids and blood ketone bodies in Japanese patients with type 2 diabetes mellitus. METHODS: Patients (baseline mean [standard deviation] glycated hemoglobin 7.91% [0.80%]; body mass index 24.3 [3.2] kg/m2) were randomized to empagliflozin 10 mg (n = 20), empagliflozin 25 mg (n = 19), or placebo (n = 21) daily as monotherapy for 28 days. Meal tolerance tests (MTTs; breakfast, lunch, dinner) were performed on day - 1, day 1 (first day of treatment), and day 28. On day 1 and day 28, study drug was administered 1 h before breakfast. Free fatty acids and blood ketone bodies were measured before and 1, 2, and 3 h after each MTT, and the next morning (overnight fast). RESULTS: Empagliflozin significantly reduced plasma glucose and insulin and reduced body weight vs. placebo. Empagliflozin increased free fatty acids and total ketones bodies at day 1 and day 28. At day 28, the adjusted mean (95% confidence interval) difference vs. placebo in the time-corrected area under curve over 24 h for total ketone bodies was 67.1 (12.3, 121.8) µmol·h/L·h (P = 0.017) with empagliflozin 10 mg and 178.1 (123.9, 232.2) µmol·h/L·h (P < 0.001) with empagliflozin 25 mg. Increases in ketones with empagliflozin vs. placebo peaked just before and declined after meals, with the highest peak before breakfast. Changes in total ketone bodies appeared to be associated with changes in plasma glucose, insulin, and free fatty acids. CONCLUSION: Empagliflozin modestly increased free fatty acids and blood ketone bodies after a single dose and 28 days' treatment. Increases in ketones appeared to be related to the duration of fasting and were most pronounced before breakfast. Increases in ketones appeared to be associated with changes in well-known metabolic determinants of ketone production. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01947855.

PURPOSE: To develop and validate algorithms to classify diabetes type in newly diagnosed pediatric patients with DM. METHOD: Data from the United States Department of Defense health system were used to identify patients aged 10 to 18 years with incident DM. Two independent sets of 200 children were randomly sampled for algorithm development and validation. Algorithms were developed based on clinical insight, published literature, and quantitative approaches. The actual DM type was ascertained via chart review. Finally, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were evaluated. RESULTS: Among the 400 patients, mean age was 14.2 (±2.5 years), and 50% were female. The best performing algorithms were based on data available in claims. They consisted of several logical expressions based on one predictor or more, which classified patients by use of glucose-lowering drugs or testing, DM ICD-9 diagnosis codes, and comorbidities. The best performing T2DM and T1DM algorithms achieved 90% and 98% sensitivity, 95% and 95% specificity, 87% and 98% PPV, and 96% and 96% NPV, respectively. CONCLUSIONS: Our results suggest that claims algorithms can accurately identify newly diagnosed T1DM and T2DM pediatric patients, which can facilitate large database studies in children with T1DM and T2DM. However, external validation in other data sources is needed.

BACKGROUND: In the EMPA-REG OUTCOME trial (BI 10773 [Empagliflozin] Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) in patients with type 2 diabetes mellitus and atherosclerotic cardiovascular disease, in comparison with placebo, empagliflozin reduced the risks of 3-point major adverse cardiovascular events (3-point MACE), cardiovascular and all-cause death, and hospitalization for heart failure. We investigated whether these effects varied across the spectrum of baseline cardiovascular risk. METHODS: Cardiovascular death, all-cause mortality, 3-point MACE, and hospitalization for heart failure in the pooled empagliflozin and placebo groups were analyzed in subgroups by prior myocardial infarction and stroke at baseline, and by estimated baseline cardiovascular risk based on the 10-point TIMI (Thrombolysis In Myocardial Infarction) Risk Score for Secondary Prevention. RESULTS: Of 7020 patients who received the study drug, 65% had a prior myocardial infarction or stroke, and 12%, 40%, 30%, and 18% were at low, intermediate, high, and highest estimated cardiovascular risk according to TIMI Risk Score for Secondary Prevention (≤2, 3, 4, and ≥5 points, respectively). In the placebo group, 3-point MACE occurred during the trial in 7.3%, 9.4%, 12.6%, and 20.6% of patients at low, intermediate, high, and highest estimated baseline risk, respectively. Relative reductions in risk of cardiovascular death, all-cause mortality, 3-point MACE and hospitalization for heart failure with empagliflozin versus placebo were consistent in patients with and without prior myocardial infarction and/or stroke and across subgroups by TIMI Risk Score for Secondary Prevention at baseline ( P>0.05 for randomized group-by-subgroup interactions). CONCLUSIONS: Despite all patients having atherosclerotic cardiovascular disease, patients in EMPA-REG OUTCOME demonstrated a broad risk spectrum for cardiovascular events. Reductions in key cardiovascular outcomes and mortality with empagliflozin versus placebo were consistent across the range of cardiovascular risk.

AIMS/INTRODUCTION: We investigated the safety and tolerability of empagliflozin (EMPA) in East Asian patients with type 2 diabetes. MATERIALS AND METHODS: Data were pooled from participants with type 2 diabetes evenly randomized to a placebo, EMPA 10 mg or EMPA 25 mg in 15 phase I-III trials. Adverse events (AEs) were analyzed in the subgroup of trial participants from East Asian countries/regions. RESULTS: In total, 709, 724 and 708 East Asian trial participants with type 2 diabetes received a placebo, EMPA 10 mg and EMPA 25 mg, respectively; total exposure was 953, 1,072, and 1,033 patient-years in these groups, respectively. The EMPA and placebo groups had similar incidences of severe AEs, serious AEs and AEs leading to discontinuation. Incidences of hypoglycemia differed according to anti-diabetes medication used at baseline. Higher rates of events consistent with genital infection were observed with EMPA (EMPA 1.5-1.7/100, placebo 0.2/100 patient-years). Rates of AEs consistent with volume depletion were comparable among treatment groups (0.8-1.4/100 patient-years), but in trial participants aged ≥65 years, the rate was greater with EMPA 25 mg (EMPA 25 mg 3.5/100, placebo 2.0/100 patient-years). Incidences of events consistent with urinary tract infection, thromboembolic events, renal events, hepatic AEs, diabetic ketoacidosis, fractures and lower limb amputation were similar between EMPA and the placebo. CONCLUSIONS: In the present pooled analysis, EMPA was well tolerated in East Asian type 2 diabetes patients based on >2,100 patient-years' exposure, consistent with results from the overall analysis population.

OBJECTIVE: To evaluate the safety and efficacy of empagliflozin 10- and 25-mg doses plus a unique lower dose (2.5 mg) as adjunct to intensified insulin in patients with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS: The EASE (Empagliflozin as Adjunctive to inSulin thErapy) program (N = 1,707) included two double-blind, placebo-controlled phase 3 trials: EASE-2 with empagliflozin 10 mg (n = 243), 25 mg (n = 244), and placebo (n = 243), 52-week treatment; and EASE-3 with empagliflozin 2.5 mg (n = 241), 10 mg (n = 248), 25 mg (n = 245), and placebo (n = 241), 26-week treatment. Together they evaluated empagliflozin 10 mg and 25 mg, doses currently approved in treatment of type 2 diabetes, and additionally 2.5 mg on 26-week change in glycated hemoglobin (primary end point) and weight, glucose time-in-range (>70 to ≤180 mg/dL), insulin dose, blood pressure, and hypoglycemia. RESULTS: The observed largest mean placebo-subtracted glycated hemoglobin reductions were -0.28% (95% CI -0.42, -0.15) for 2.5 mg, -0.54% (-0.65, -0.42) for 10 mg, and -0.53% (-0.65, -0.42) for 25 mg (all P < 0.0001). Empagliflozin 2.5/10/25 mg doses, respectively, reduced mean weight by -1.8/-3.0/-3.4 kg (all P < 0.0001); increased glucose time-in-range by +1.0/+2.9/+3.1 h/day (P < 0.0001 for 10 and 25 mg); lowered total daily insulin dose by -6.4/-13.3/-12.7% (all P < 0.0001); and decreased systolic blood pressure by -2.1/-3.9/-3.7 mmHg (all P < 0.05). Genital infections occurred more frequently on empagliflozin. Adjudicated diabetic ketoacidosis occurred more with empagliflozin 10 mg (4.3%) and 25 mg (3.3%) but was comparable between empagliflozin 2.5 mg (0.8%) and placebo (1.2%). Severe hypoglycemia was rare and frequency was similar between empagliflozin and placebo. CONCLUSIONS: Empagliflozin improved glycemic control and weight in T1D without increasing hypoglycemia. Ketoacidosis rate was comparable between empagliflozin 2.5 mg and placebo but increased with 10 mg and 25 mg. Ketone monitoring for early ketoacidosis detection and intervention and lower empagliflozin doses may help to reduce this risk.

OBJECTIVE: To assess the effect of empagliflozin on bone fractures and bone mineral density in patients with type 2 diabetes in pooled placebo-controlled trial data and a head-to-head study versus glimepiride. RESEARCH DESIGN AND METHODS: Pooled data were analyzed from patients who were randomized 1:1:1 to empagliflozin 10 mg, empagliflozin 25 mg, or placebo in phase I-III clinical trials. Data were also analyzed from the EMPA-REG H2H-SU trial in which patients received empagliflozin 25 mg or glimepiride as an add-on to metformin for 104 weeks with a 104-week extension. Bone fracture adverse events (AEs) were evaluated through a search of investigator-reported (nonadjudicated) events. RESULTS: In the pooled analysis, bone fracture AEs were reported in 119 of 4,221 (2.8%), 105 of 4,196 (2.5%), and 123 of 4,203 (2.9%) patients in the empagliflozin 10 mg, empagliflozin 25 mg, and placebo groups, respectively (rates of 1.55, 1.36, and 1.69/100 patient-years, respectively). In the EMPA-REG H2H-SU trial, bone fracture AEs were reported in 31 of 765 (4.1%) patients receiving empagliflozin 25 mg and in 33 of 780 (4.2%) patients receiving glimepiride (rates of 1.28 and 1.40/100 patient-years, respectively). CONCLUSIONS: Empagliflozin did not increase the risk of bone fracture compared with placebo in a pooled analysis of >12,000 patients or compared with glimepiride in a 4-year head-to-head study.

INTRODUCTION: Empagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, ameliorates hyperglycemia in patients with type 2 diabetes (T2D) by inducing sustained glucosuria. Empagliflozin treatment was previously associated with a transient increase in 24-h urine volume in Caucasian patients with T2D, however comparable evidence in Japanese T2D individuals is scarce. We therefore assessed acute and chronic changes in 24-h urine volume and fluid intake with empagliflozin in Japanese patients with T2D. METHODS: In this randomized, double-blind, placebo-controlled, parallel-group, multiple-dose, 4-week trial, 100 Japanese patients with T2D were randomized to receive either 1, 5, 10, or 25 mg empagliflozin or placebo once-daily. Changes from baseline in 24-h urine volume and fluid intake were assessed at days 1, 27, and 28 after the initiation of empagliflozin. RESULTS: The 24-h urine volume and fluid intake were comparable across all treatment groups at baseline. Patients treated with either 10 or 25 mg empagliflozin (i.e., the licensed doses in Japan) showed a significant increase in 24-h urine volume compared to placebo at day 1 (mean change from baseline: + 0.83, + 1.08, and + 0.29 L/day in the empagliflozin 10 and 25 mg groups and the placebo group, respectively; both p < 0.001 vs. placebo). However, 24-h urine volume levels in the empagliflozin groups were comparable to placebo at day 27 and 28 (differences vs placebo < 0.1 L/day; p > 0.05). The 24-h fluid intake was comparable across all study groups throughout the entire study period. No events consistent with dehydration were reported during empagliflozin treatment. CONCLUSION: Treatment initiation with empagliflozin in Japanese patients with T2D was associated with transient diuresis; however, overall urine volume returned towards baseline levels within 4 weeks of treatment. These findings are consistent with a physiological, adaptive mechanism of the kidney to maintain overall body fluid balance in response to treatment initiation with a SGLT2 inhibitor.

RESUMEN
Sodium glucose cotransporter 2 inhibitors increase urinary glucose excretion (UGE) by lowering the renal threshold for glucose (RTG ). We aimed to quantify the effect of the sodium glucose cotransporter inhibitor empagliflozin on renal glucose reabsorption in patients with type 1 diabetes mellitus (T1DM) using a mechanistic population pharmacokinetic-pharmacodynamic (PK-PD) model and to compare results with analyses in patients with type 2 diabetes mellitus (T2DM). The PK-PD model was developed using data from a randomized phase 2 study in which patients with T1DM received oral once-daily empagliflozin 2.5 mg, empagliflozin 10 mg, empagliflozin 25 mg, or placebo as an adjunct to insulin. The model assumed that UGE was dependent on plasma glucose and renal function and that empagliflozin lowered RTG . The final model was evaluated using visual predictive checks and found to be consistent with observed data. Calculated RTG with placebo was 181 mg/dL, and with empagliflozin (steady state) 1 mg and 2.5 mg was 53.4 mg/dL and 12.5 mg/dL, respectively. Empagliflozin 10 mg and 25 mg yielded negative RTG values, implying RTG was reduced to a negligible value. Although estimated PK-PD parameters were generally comparable between patients with T1DM and patients with T2DM, slight differences were evident, leading to lower RTG and higher UGE in patients with T1DM compared with patients with T2DM. In conclusion, the model provided a reasonable description of UGE in response to administration of empagliflozin and placebo in patients with T1DM.

OBJECTIVE: To identify the dose of the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin in pediatric patients with type 2 diabetes (T2D). METHODS: Double-blind, randomized, controlled parallel group study comparing linagliptin 1 and 5 mg once daily, with placebo in 39 patients with T2D aged 10 to below 18 years. The primary efficacy endpoint was the change from baseline in glycated hemoglobin (HbA1c) after 12 weeks of treatment. The key pharmacodynamic endpoint was DPP-4 inhibition during steady-state. RESULTS: Compared to placebo, there was a dose-dependent reduction in mean HbA1c of 0.48% and 0.63% with linagliptin 1 and 5 mg, respectively, associated with corresponding declines in mean fasting plasma glucose (FPG) of 5.6 and 34.2 mg/dL. Median DPP-4 inhibition was 38% with linagliptin 1 mg and 79% with linagliptin 5 mg. Geometric mean trough levels of linagliptin were 3.80 and 7.42 nmol/L in the 1 and 5 mg groups, respectively; levels that were slightly higher than in adult patients with T2D that were most likely caused by higher plasma DPP-4 concentrations in the study population. There were no drug-related adverse events during treatment with either dose of linagliptin. CONCLUSIONS: Linagliptin was well tolerated and induced dose-dependent DPP-4 inhibition that was accompanied by corresponding reductions in HbA1c and FPG levels in young people with T2D. The results are consistent with the clinical efficacy and safety profile that have been reported for linagliptin in adult patients with T2D, favoring linagliptin 5 mg over 1 mg.
