Treatment patterns and glycated haemoglobin levels over 36 months in individuals with type 2 diabetes initiating second-line glucose-lowering therapy: The global DISCOVER study.

AIMS: To describe glucose-lowering treatment regimens and glycated haemoglobin (HbA1c) trajectories in individuals with type 2 diabetes (T2D) over 36 months of follow-up from the start of second-line therapy. MATERIALS AND METHODS: This data analysis from the 3-year, observational DISCOVER study programme included 14 687 participants from 37 countries with T2D initiating second-line glucose-lowering therapy. Treatment and HbA1c data were collected at baseline (start of second-line therapy) and at 6, 12, 24 and 36 months. Treatment regimen changes over follow-up were analysed using the McNemar test, with carry-forward imputation for intermediate missing values. RESULTS: A total of 11 592 participants had treatment data at baseline and 36 months, and 11 882 had HbA1c data at baseline. At baseline and 36 months, respectively, rates of oral monotherapy use were 12.1% and 12.4% (P = 0.22), rates of dual oral therapy use were 63.4% and 47.6% (P < 0.0001), rates of ≥ triple oral therapy use were 17.5% and 25.4% (P < 0.0001), and rates of injectable treatment use were 7.0% and 13.7% (P < 0.0001). Use of injectable drugs was most common among participants with an HbA1c level ≥64 mmol/mol (≥8.0%). Overall, 42.9% of participants changed treatment during follow-up. Mean HbA1c levels at baseline and 6 months were 67 mmol/mol (8.3%) and 55 mmol/mol (7.2%), respectively, remaining stable thereafter. CONCLUSIONS: Dual oral therapy was the most common treatment regimen at the start of second-line treatment, and over half of the participants remained on the same treatment during follow-up.

Inappropriate intensification of glucose-lowering treatment in older patients with type 2 diabetes: the global DISCOVER study.

INTRODUCTION: Although individualized target glycated hemoglobin (HbA1c) levels are recommended in older people with type 2 diabetes, studies report high levels of potential overtreatment. We aimed to investigate the proportion of older patients (aged ≥65 years) who potentially received an inappropriately intensive treatment (HbA1c level <7.0% (53.0 mmol/mol)) in a global study. Factors associated with intensive glycemic management and using glucose-lowering medications associated with a high risk of hypoglycemia (high-risk medications (insulin, sulfonylureas, and meglitinides)) were also assessed. RESEARCH DESIGN AND METHODS: DISCOVER is a 3-year observational study program of 15 992 people with type 2 diabetes initiating second-line glucose-lowering therapy in 38 countries. Data were collected at baseline (initiation of second-line therapy) and at 6, 12, and 24 months. Factors associated with an inappropriately intensive treatment or using high-risk medications were assessed using a hierarchical regression model. RESULTS: Of the 3344 older patients with baseline HbA1c data in our analytic cohort, 23.5% received inappropriate treatment intensification. Among those who had follow-up HbA1c data, 55.2%, 54.2%, and 53.5% were inappropriately tightly controlled at 6, 12, and 24 months, respectively, with higher proportions in high-income than in middle-income countries. The proportion of patients receiving high-risk medications was higher in middle-income countries than in high-income countries. Gross national income (per US$5000 increment) was associated with increased odds of inappropriately intensive treatment but with decreased odds of receiving high-risk medications. CONCLUSIONS: A large proportion of older DISCOVER patients received an inappropriately intensive glucose-lowering treatment across the 2 years of follow-up, with substantial regional variation. The use of high-risk medications in these patients is particularly concerning.

Prevalence and progression of chronic kidney disease among patients with type 2 diabetes: Insights from the DISCOVER study.

We report the prevalence and change in severity of chronic kidney disease (CKD) in DISCOVER, a global, 3-year, prospective, observational study of patients with type 2 diabetes (T2D) initiating second-line glucose-lowering therapy. CKD stages were defined according to estimated glomerular filtration rate (eGFR). Overall, 7843 patients from 35 countries had a baseline serum creatinine measurement. Of these (56.7% male; mean age: 58.1 years; mean eGFR: 87.5 mL/min/1.73 m2 ), baseline prevalence estimates for stage 0-1, 2, 3 and 4-5 CKD were 51.4%, 37.7%, 9.4% and 1.4%, respectively. A total of 5819 patients (74.2%) also had at least one follow-up serum creatinine measurement (median time between measurements: 2.9 years, interquartile range: 1.9-3.0 years). Mean eGFR decreased slightly to 85.7 mL/min/1.73 m2 over follow-up. CKD progression (increase of ≥1 stage) occurred in 15.7% of patients, and regression (decrease of ≥1 stage) in 12.0%. In summary, a substantial proportion of patients with T2D developed CKD or had CKD progression after the initiation of second-line therapy. Renal function should be regularly monitored in these patients, to ensure early CKD diagnosis and treatment.

Associations between second-line glucose-lowering combination therapies with metformin and HbA1c, body weight, quality of life, hypoglycaemic events and glucose-lowering treatment intensification: The DISCOVER study.

AIM: To explore the effects of second-line combination therapies with metformin on body weight, HbA1c and health-related quality of life, as well as the risks of hypoglycaemia and further treatment intensification in the DISCOVER study, a 3-year, prospective, global observational study of patients with type 2 diabetes initiating second-line glucose-lowering therapy. MATERIALS AND METHODS: Adjusted changes from baseline in weight, HbA1c and 36-item Short Form Health Survey version 2 (SF-36v2) summary scores at 6, 12, 24 and 36 months were assessed using linear mixed models. Risk of hypoglycaemia and further intensification were assessed using interval censored analyses. RESULTS: At baseline, 7613 patients received metformin in combination with a sulphonylurea (SU; 40.9%), a dipeptidyl peptidase-4 (DPP-4) inhibitor (48.3%), a sodium-glucose co-transporter-2 (SGLT-2) inhibitor (8.3%) or a glucagon-like peptide-1 (GLP-1) receptor agonist (2.4%). After 36 months, all combinations showed similar reductions in HbA1c (0.8%-1.0%), however, metformin plus a DPP-4 inhibitor, an SGLT-2 inhibitor or a GLP-1 receptor agonist was associated with greater weight loss (1.9, 2.9 and 5.0 kg, respectively) than metformin plus an SU (1.3 kg, P < .0001). Proportions of further treatment intensification were similar across combinations (19.9%-26.2%). Patients prescribed metformin plus an SU more often reported one or more hypoglycaemic events (11.9%) than other combinations (3.9%-6.4%, P < .0001). SF-36v2 summary scores were typically lowest among patients prescribed metformin and an SU. CONCLUSIONS: Combinations of metformin with an SU were associated with the lowest weight reduction, highest risk of hypoglycaemia and lower SF-36v2 scores.

Effects of ertugliflozin on kidney composite outcomes, renal function and albuminuria in patients with type 2 diabetes mellitus: an analysis from the randomised VERTIS CV trial.

AIMS/HYPOTHESIS: In previous work, we reported the HR for the risk (95% CI) of the secondary kidney composite endpoint (time to first event of doubling of serum creatinine from baseline, renal dialysis/transplant or renal death) with ertugliflozin compared with placebo as 0.81 (0.63, 1.04). The effect of ertugliflozin on exploratory kidney-related outcomes was evaluated using data from the eValuation of ERTugliflozin effIcacy and Safety CardioVascular outcomes (VERTIS CV) trial (NCT01986881). METHODS: Individuals with type 2 diabetes mellitus and established atherosclerotic CVD were randomised to receive ertugliflozin 5 mg or 15 mg (observations from both doses were pooled), or matching placebo, added on to existing treatment. The kidney composite outcome in VERTIS CV (reported previously) was time to first event of doubling of serum creatinine from baseline, renal dialysis/transplant or renal death. The pre-specified exploratory composite outcome replaced doubling of serum creatinine with sustained 40% decrease from baseline in eGFR. In addition, the impact of ertugliflozin on urinary albumin/creatinine ratio (UACR) and eGFR over time was assessed. RESULTS: A total of 8246 individuals were randomised and followed for a mean of 3.5 years. The exploratory kidney composite outcome of sustained 40% reduction from baseline in eGFR, chronic kidney dialysis/transplant or renal death occurred at a lower event rate (events per 1000 person-years) in the ertugliflozin group than with the placebo group (6.0 vs 9.0); the HR (95% CI) was 0.66 (0.50, 0.88). At 60 months, in the ertugliflozin group, placebo-corrected changes from baseline (95% CIs) in UACR and eGFR were -16.2% (-23.9, -7.6) and 2.6 ml min-1 [1.73 m]-2 (1.5, 3.6), respectively. Ertugliflozin was associated with a consistent decrease in UACR and attenuation of eGFR decline across subgroups, with a suggested larger effect observed in the macroalbuminuria and Kidney Disease: Improving Global Outcomes in Chronic Kidney Disease (KDIGO CKD) high/very high-risk subgroups. CONCLUSIONS/INTERPRETATION: Among individuals with type 2 diabetes and atherosclerotic CVD, ertugliflozin reduced the risk for the pre-specified exploratory composite renal endpoint and was associated with preservation of eGFR and reduced UACR.

Glycaemic control and hypoglycaemia risk with insulin glargine 300 U/mL and insulin degludec 100 U/mL in older participants in the BRIGHT trial.

AIM: To evaluate the efficacy and safety of insulin glargine 300 U/mL (Gla-300) versus insulin degludec 100 U/mL (IDeg-100) in predefined (

Type 2 diabetes and heart failure: insights from the global DISCOVER study.

AIMS: Heart failure (HF) is increasingly recognized as a major cause of morbidity and mortality in patients with type 2 diabetes (T2D), but the global epidemiology and treatment of HF in T2D are not well defined. This study aimed to examine the global prevalence of HF and the incidence of HF over 3 years of follow-up in patients with T2D [by presence and absence of co-existing coronary artery disease (CAD)]. METHODS AND RESULTS: DISCOVER was a 3 year, prospective, observational study of T2D patients enrolled at initiation of second-line glucose-lowering therapy. Among 14 057 patients with T2D from 36 countries, 289 (2.1%) had a diagnosis of HF at enrolment; median prevalence across countries was 2.0% (inter-quartile range 1.0-3.1%). Patients with HF at baseline were more likely to be older [HF vs. no HF: 67 ± 12 vs. 57 ± 12 years, standardized difference (StDiff) = 84%] and have longer duration of T2D (8.1 ± 7.2 vs. 5.6 ± 5.2 years, StDiff = 40%), CAD (44% vs. 6%, StDiff = 97%), atrial fibrillation (21% vs. 1%, StDiff = 66%), and kidney disease (23% vs. 4%, StDiff = 55%). Patients with HF were less likely to be on metformin (66% vs. 79%, StDiff = 28%) and thiazolidinediones (5.5% vs. 10.6%, StDiff = 19%) but had similar use of other glucose-lowering medications. Among 9313 patients with follow-up data, there were 70 incident cases of HF, which translates to an incidence of 2.6 cases per 1000 person years. Of these incident HF cases, 60% occurred in the absence of pre-existing or concomitant CAD, and 73% were diagnosed in the outpatient setting. CONCLUSIONS: In a large, global cohort of patients with T2D, the majority of incident cases of HF occurred in outpatients and in the absence of known CAD. These findings highlight the need for greater awareness of HF risk in patients with T2D.

Global patterns of comprehensive cardiovascular risk factor control in patients with type 2 diabetes mellitus: Insights from the DISCOVER study.

AIM: To investigate global patterns of cardiovascular risk factor control in patients with type 2 diabetes mellitus (T2D). METHODS: DISCOVER is an international, observational cohort study of patients with T2D beginning second-line glucose-lowering therapy. Risk factor management was examined among eligible patients (ie, those with the risk factor) at study baseline. Inter-country variability was estimated using median odds ratios (MORs). RESULTS: Among 14 343 patients with T2D from 34 countries, the mean age was 57.4 ± 12.0 years and the median (interquartile range) duration of T2D was 4.2 (2.0-8.0) years; 11.8% had documented atherosclerotic cardiovascular disease (ASCVD). Among eligible patients, blood pressure was controlled in 67.5% (9284/13756), statins were prescribed in 43.7% (5775/13208), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers were prescribed in 55.6% (5292/9512), aspirin was prescribed in 53.3% of those with established ASCVD (876/1645), and 84.4% (12 102/14343) were non-smoking. Only 21.5% of patients (3088/14343) had optimal risk factor management (defined as control of all eligible measures), with wide inter-country variability (10%-44%), even after adjusting for patient and site differences (MOR 1.47, 95% confidence interval 1.24-1.66). CONCLUSION: Globally, comprehensive control of ASCVD risk factors is not being achieved in most patients, with wide variability among countries unaccounted for by patient and site differences. Better country-specific strategies are needed to implement comprehensive cardiovascular risk factor control consistently in patients with T2D to improve long-term outcomes.

Association of SGLT2 Inhibitors With Cardiovascular and Kidney Outcomes in Patients With Type 2 Diabetes: A Meta-analysis.

Importance: Sodium-glucose cotransporter 2 (SGLT2) inhibitors favorably affect cardiovascular (CV) and kidney outcomes; however, the consistency of outcomes across the class remains uncertain. Objective: To perform meta-analyses that assess the CV and kidney outcomes of all 4 available SGLT2 inhibitors in patients with type 2 diabetes. Data Sources: A systematic literature search was conducted in PubMed from January 1, 2015, to January 31, 2020. Study Selection: One hundred forty-five records were initially identified; 137 were excluded because of study design or topic of interest. As a result, a total of 6 randomized, placebo-controlled CV and kidney outcomes trials of SGLT2 inhibitors in patients with type 2 diabetes were identified, with contributory data from 9 publications. All analyses were conducted on the total patient population of these trials. Data Extraction and Synthesis: Standardized data search and abstraction were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Statement. Data were analyzed using a fixed-effect model. Main Outcomes and Measures: Outcomes included time to the first event of (1) the composite of major adverse CV events of myocardial infarction, stroke, or CV death, and each component, (2) the composite of hospitalization for heart failure (HHF) or CV death (HHF/CV death) and each component, and (3) kidney composite outcomes. For outcomes in the overall trial populations and in selected subgroups, hazard ratios (HRs) and 95% CIs were pooled and meta-analyzed across trials. Results: Data from 6 trials comprised 46 969 unique patients with type 2 diabetes, including 31 116 (66.2%) with atherosclerotic CV disease. The mean (SD) age of all trial participants was 63.7 (7.9) years; 30 939 (65.9%) were men, and 36 849 (78.5%) were White. The median number of participants per trial was 8246 (range, 4401-17 160). Overall, SGLT2 inhibitors were associated with a reduced risk of major adverse CV events (HR, 0.90; 95% CI, 0.85-0.95; Q statistic, P = .27), HHF/CV death (HR, 0.78; 95% CI, 0.73-0.84; Q statistic, P = .09), and kidney outcomes (HR, 0.62; 95% CI, 0.56-0.70; Q statistic, P = .09), with no significant heterogeneity of associations with outcome. Associated risk reduction for HHF was consistent across the trials (HR, 0.68; 95% CI, 0.61-0.76; I2 = 0.0%), whereas significant heterogeneity of associations with outcome was observed for CV death (HR, 0.85; 95% CI, 0.78-0.93; Q statistic, P = .02; I2 = 64.3%). The presence or absence of atherosclerotic CV disease did not modify the association with outcomes for major adverse CV events (HR, 0.89; 95% CI, 0.84-0.95 and HR, 0.94; 95% CI, 0.83-1.07, respectively; P = .63 for interaction), with similar absence of associations with outcome modification by prevalent atherosclerotic CV disease for HHF/CV death (P = .62 for interaction), HHF (P = .26 for interaction), or kidney outcomes (P = .73 for interaction). Conclusions and Relevance: In this meta-analysis, SGLT2 inhibitors were associated with a reduced risk of major adverse CV events; in addition, results suggest significant heterogeneity in associations with CV death. The largest benefit across the class was for an associated reduction in risk for HHF and kidney outcomes, with benefits for HHF risk being the most consistent observation across the trials.

Efficacy of Ertugliflozin on Heart Failure-Related Events in Patients With Type 2 Diabetes Mellitus and Established Atherosclerotic Cardiovascular Disease: Results of the VERTIS CV Trial.

BACKGROUND: In patients with type 2 diabetes mellitus, sodium-glucose cotransporter 2 inhibitors reduce the risk of hospitalization for heart failure (HHF). We assessed the effect of ertugliflozin on HHF and related outcomes. METHODS: VERTIS CV (Evaluation of Ertugliflozin Efficacy and Safety Cardiovascular Outcomes Trial), a double-blind, placebo-controlled trial, randomly assigned patients with type 2 diabetes mellitus and atherosclerotic cardiovascular (CV) disease to once-daily ertugliflozin 5 mg, 15 mg, or placebo. Prespecified secondary analyses compared ertugliflozin (pooled doses) versus placebo on time to first event of HHF and composite of HHF/CV death, overall and stratified by prespecified characteristics. Cox proportional hazards modeling was used with the Fine and Gray method to account for competing mortality risk, and Andersen-Gill modeling to analyze total (first+recurrent) HHF and total HHF/CV death events. RESULTS: A total of 8246 patients were randomly assigned to ertugliflozin (n=5499) or placebo (n=2747); n=1958 (23.7%) had a history of heart failure (HF) and n=5006 (60.7%) had pretrial ejection fraction (EF) available, including n=959 with EF ≤45%. Ertugliflozin did not significantly reduce first HHF/CV death (hazard ratio [HR], 0.88 [95% CI, 0.75-1.03]). Overall, ertugliflozin reduced risk for first HHF (HR, 0.70 [95% CI, 0.54-0.90]; P=0.006). Previous HF did not modify this effect (HF: HR, 0.63 [95% CI, 0.44-0.90]; no HF: HR, 0.79 [95% CI, 0.54-1.15]; P interaction=0.40). In patients with HF, the risk reduction for first HHF was similar for those with reduced EF ≤45% versus preserved EF >45% or unknown. However, in the overall population, the risk reduction tended to be greater for those with EF ≤45% (HR, 0.48 [95% CI, 0.30-0.76]) versus EF >45% (HR, 0.86 [95% CI, 0.58-1.29]). Effect on risk for first HHF was consistent across most subgroups, but greater benefit of ertugliflozin was observed in 3 populations: baseline estimated glomerular filtration rate <60 mL·min-1·1.73 m-2, albuminuria, and diuretic use (each P interaction <0.05). Ertugliflozin reduced total events of HHF (rate ratio, 0.70 [95% CI, 0.56-0.87]) and total HHF/CV death (rate ratio, 0.83 [95% CI, 0.72-0.96]). CONCLUSIONS: In patients with type 2 diabetes mellitus, ertugliflozin reduced the risk for first and total HHF and total HHF/CV death, adding further support for the use of sodium-glucose cotransporter 2 inhibitors in primary and secondary prevention of HHF.

Cardiovascular Outcomes with Ertugliflozin in Type 2 Diabetes.

BACKGROUND: The cardiovascular effects of ertugliflozin, an inhibitor of sodium-glucose cotransporter 2, have not been established. METHODS: In a multicenter, double-blind trial, we randomly assigned patients with type 2 diabetes and atherosclerotic cardiovascular disease to receive 5 mg or 15 mg of ertugliflozin or placebo once daily. With the data from the two ertugliflozin dose groups pooled for analysis, the primary objective was to show the noninferiority of ertugliflozin to placebo with respect to the primary outcome, major adverse cardiovascular events (a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke). The noninferiority margin was 1.3 (upper boundary of a 95.6% confidence interval for the hazard ratio [ertugliflozin vs. placebo] for major adverse cardiovascular events). The first key secondary outcome was a composite of death from cardiovascular causes or hospitalization for heart failure. RESULTS: A total of 8246 patients underwent randomization and were followed for a mean of 3.5 years. Among 8238 patients who received at least one dose of ertugliflozin or placebo, a major adverse cardiovascular event occurred in 653 of 5493 patients (11.9%) in the ertugliflozin group and in 327 of 2745 patients (11.9%) in the placebo group (hazard ratio, 0.97; 95.6% confidence interval [CI], 0.85 to 1.11; P<0.001 for noninferiority). Death from cardiovascular causes or hospitalization for heart failure occurred in 444 of 5499 patients (8.1%) in the ertugliflozin group and in 250 of 2747 patients (9.1%) in the placebo group (hazard ratio, 0.88; 95.8% CI, 0.75 to 1.03; P = 0.11 for superiority). The hazard ratio for death from cardiovascular causes was 0.92 (95.8% CI, 0.77 to 1.11), and the hazard ratio for death from renal causes, renal replacement therapy, or doubling of the serum creatinine level was 0.81 (95.8% CI, 0.63 to 1.04). Amputations were performed in 54 patients (2.0%) who received the 5-mg dose of ertugliflozin and in 57 patients (2.1%) who received the 15-mg dose, as compared with 45 patients (1.6%) who received placebo. CONCLUSIONS: Among patients with type 2 diabetes and atherosclerotic cardiovascular disease, ertugliflozin was noninferior to placebo with respect to major adverse cardiovascular events.

Efficacy and safety of ertugliflozin in older patients with type 2 diabetes: A pooled analysis of phase III studies.

AIM: To assess the efficacy and safety of ertugliflozin in older patients with type 2 diabetes (T2D). MATERIALS AND METHODS: This is a post hoc analysis of patients with T2D aged less than 65 years and those aged 65 years or older who participated in randomized, double-blind, phase III studies of ertugliflozin. Efficacy was evaluated in a pooled analysis of three placebo-controlled studies (ertugliflozin monotherapy and add-on therapy). Safety was evaluated in a pooled analysis of seven placebo- and active-controlled studies (including those used for efficacy). Least-squares mean change from baseline was calculated for HbA1c, fasting plasma glucose (FPG), body weight (BW) and systolic blood pressure (SBP). Safety evaluation included overall and prespecified adverse events (AEs). RESULTS: In participants aged less than 65 years, the placebo-adjusted mean changes from baseline in HbA1c, BW and SBP with ertugliflozin 5 and 15 mg at week 26 were -0.9% and -1.0%, -1.9 and -1.8 kg, and -3.7 and -3.6 mmHg, respectively; in participants aged 65 years or older they were -0.6% and -0.8%, -1.9 and -2.2 kg, and -2.7 and -3.4 mmHg, respectively. The incidences of AEs, serious AEs, discontinuations and deaths in participants aged less than 65 years and those aged 65 years or older were generally similar across the treatment groups. In patients aged 65 years or older the incidences of volume depletion AEs and genital mycotic infection were higher with ertugliflozin than with non-ertugliflozin. CONCLUSIONS: Ertugliflozin improved glycaemic control, BW and SBP in younger and older individuals with T2D and was generally well tolerated in both groups.

Persistence with Basal Insulin and Frequency of Hypoglycemia Requiring Hospitalization in Patients with Type 2 Diabetes.

INTRODUCTION: A second-generation basal insulin analogue insulin glargine 300 U/mL (Gla-300) has been marketed in France since June 2016. This real-world study was designed to assess persistence with Gla-300 and the prevalence of related hypoglycemia requiring hospitalization as compared to first-generation basal insulins, in patients with type 2 diabetes mellitus (T2DM). METHODS: A retrospective study was conducted using data in the large French comprehensive national healthcare system claims databases. Patients with T2DM newly treated with insulin in 2016 and 2017 (2-year period) were included. Three basal insulins [Gla-300, glargine 100 U/mL (Gla-100; both branded and biosimilar) and insulin detemir (IDet)] were compared for (1) persistence until treatment discontinuation using adjusted Cox models and (2) hypoglycemia requiring hospitalization over the period of insulin exposure. RESULTS: During the 2-year study period, in France, 181,263 patients initiated basal insulin therapy (in a basal scheme or a more complex insulin scheme), of whom 74% initiated Gla-100, 14.2% initiated IDet and 11.8% initiated Gla-300. Patient characteristics varied according to the insulin regimen in terms of age, gender, social coverage, insulin scheme, and Charlson Comorbidity Index. Overall, 72% of patients were still treated with any basal insulin after 1 year (75% in basal scheme). In all insulin treatment regimens, patients were less likely to discontinue Gla-300 as compared to Gla-100 [adjusted odds ratio (OR) 0.39, 95% confidence interval (CI) 0.37-0.41], with similar results when only the basal scheme was considered (adjusted OR 0.38, 95% CI 0.35-0.40). Persistence with IDet was similar to that with Gla-100. Patients treated with Gla-100 had higher crude hospitalization rates for hypoglycemia than those receiving Gla-300 (1.4 for 100 patients-years; OR 0.67, 95% CI 0.55-0.81); however, this difference was not statistically significant after adjustment for patient characteristics. Emergency Room (ER) visits were less frequent in patients treated with Gla-300 versus Gla-100 with or without adjustment for patient characteristics (p < 0.0001). CONCLUSION: Real-world persistence for basal insulin therapy in patients with T2DM was significantly better in those on Gla-300 compared with those on Gla-100 and IDet. A trend to a lower frequency of hospitalization for hypoglycemia and ER visits, whatever the cause, was also observed in patients on Gla-300.

Socioeconomic factors associated with hypoglycaemia in patients starting second-line glucose-lowering therapy: The DISCOVER study.

AIMS: Using data from DISCOVER (NCT02322762; NCT02226822), a 3-year, global, observational study programme of patients with type 2 diabetes initiating second-line glucose-lowering therapy, we assessed socioeconomic factors associated with hypoglycaemic events and fear of hypoglycaemia. METHODS: Data were collected at baseline (second-line therapy initiation) and 6, 12 and 24 months. Factors associated with experiencing a hypoglycaemic event at baseline or during follow-up were determined using a hierarchical logistic regression model and an interval-censored survival analysis, respectively. Fear of hypoglycaemia was assessed using the hypoglycaemia fear survey-II (HFS-II). RESULTS: The overall proportion of patients reporting hypoglycaemic events during follow-up was 7.3%; this was higher in middle-income countries than in high-income countries (8.4% vs 5.8%, p < 0.001). Factors associated with an increased risk of hypoglycaemia during follow-up included living in a country with a low gross national income, use of glucose-monitoring equipment and second-line treatment with insulin, meglitinides or sulphonylureas (versus metformin). Experiencing hypoglycaemia was associated with increased HFS-II worry and overall scores. CONCLUSIONS: Our results highlight the global inequity in the treatment of type 2 diabetes. Increased risk of hypoglycaemia in middle-income countries may be explained by limited treatment options and may be underestimated because of limited access to glucose-monitoring equipment.

Treatment patterns and associated factors in 14 668 people with type 2 diabetes initiating a second-line therapy: Results from the global DISCOVER study programme.

AIM: To evaluate treatment data from DISCOVER (NCT02322762 and NCT02226822), a global, prospective, observational study programme of patients with type 2 diabetes initiating a second-line glucose-lowering therapy. MATERIALS AND METHODS: Data were collected using a standardized case report form. First- and second-line treatments were assessed in 14 668 patients from 37 countries across six regions. Among patients prescribed first-line metformin monotherapy, Firth logistic regression models were used to assess factors associated with second-line treatment choices. RESULTS: The most common first-line therapies were metformin monotherapy (57.9%) and combinations of metformin with a sulphonylurea (14.6%). The most common second-line therapies were combinations of metformin with other agents (72.2%), including dipeptidyl peptidase-4 (DPP-4) inhibitors (25.1%) or sulphonylureas (21.3%). Among patients prescribed first-line metformin monotherapy, the most common second-line therapies were combinations of metformin with a DPP-4 inhibitor [32.8%; across-region range (ARR): 2.4%-51.3%] or a sulphonylurea (30.0%; ARR: 18.3%-63.6%); only a few patients received combinations of metformin with sodium-glucose co-transporter-2 inhibitors (6.7%; ARR: 0.0%-10.8%) or glucagon-like peptide-1 receptor agonists (1.9%; ARR: 0.1%-4.5%). Both clinical and non-medical factors were associated with choice of second-line therapy after metformin monotherapy. CONCLUSIONS: Fewer patients than expected received metformin monotherapy at first line, and the use of newer therapies at second line was uncommon in some regions of the world. Patients' socioeconomic status was associated with treatment patterns, suggesting that therapy choices are influenced by cost and access.

Treatment of type 2 diabetes mellitus worldwide: Baseline patient characteristics in the global DISCOVER study.

AIMS: To describe the characteristics and treatment of patients with type 2 diabetes mellitus initiating a second-line glucose-lowering therapy in the global DISCOVER study programme. METHODS: DISCOVER comprises two similar 3-year prospective observational studies (NCT02322762 and NCT02226822), involving 15,992 patients initiating a second-line glucose-lowering therapy in 38 countries across six regions (Africa, Americas, South-East Asia, Eastern Mediterranean, Europe and Western Pacific). RESULTS: Overall, 54.2% of patients were male (across region range [ARR]: 37.7-58.6%). At baseline, mean age and time since diagnosis of type 2 diabetes mellitus were 57.2 (ARR: 53.1-61.9)and 5.6 (ARR: 4.6-6.9) years, respectively. Median glycated haemoglobin (HbA1c) was 63.9 mmol/mol (8.0%; ARR: 7.6-8.3%). Microvascular and macrovascular complications were reported in 18.9% (ARR: 14.5-23.5%) and 12.7% (ARR: 5.0-26.6%) of patients, respectively. First-line treatments were mostly metformin monotherapy (55.6%; ARR: 42.5-83.6%) and combinations of metformin with a sulfonylurea (14.4%; ARR: 5.8-31.1%). The most commonly prescribed second-line therapies were combinations of metformin with a dipeptidyl peptidase-4 inhibitor (23.5%; ARR: 2.2-29.6%) or a sulfonylurea (20.9%; ARR: 13.6-57.1%). CONCLUSIONS: DISCOVER demonstrates considerable global variation in the treatment of type 2 diabetes mellitus, and a need for more aggressive risk factor control.

Long-term efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus inadequately controlled with metformin monotherapy: 104-week VERTIS MET trial.

AIM: To evaluate the long-term efficacy and safety of ertugliflozin in adults with type 2 diabetes mellitus inadequately controlled on metformin. MATERIALS AND METHODS: A 104-week Phase III, randomized double-blind study with a 26-week placebo-controlled period (Phase A) and a 78-week period (Phase B) where blinded glimepiride was added to non-rescued placebo participants with fasting fingerstick glucose ≥6.1 mmol/L. Results through week 104 are reported. RESULTS: Mean (standard error) change in HbA1c from baseline was -0.7% (0.07) and -1.0% (0.07) at week 52; -0.6% (0.08) and -0.9% (0.08) at week 104 for ertugliflozin 5 and 15 mg. At week 52, 34.8% and 36.6% participants had HbA1c <7.0%, and 24.6% and 33.7% at week 104, for ertugliflozin 5 and 15 mg. Ertugliflozin reduced fasting plasma glucose (FPG), body weight and systolic blood pressure (SBP) from baseline through week 104. The incidence of female genital mycotic infections (GMIs) was higher with ertugliflozin, and symptomatic hypoglycaemia was lower for ertugliflozin versus placebo/glimepiride. Minimal bone mineral density (BMD) changes were observed, similar to placebo/glimepiride, except at total hip where reduction in BMD was greater with ertugliflozin 15 mg versus placebo/glimepiride: difference in least squares means (95% CI) -0.50% (-0.95, -0.04) at week 52 and -0.84% (-1.44, -0.24) at week 104. CONCLUSIONS: Ertugliflozin maintained improvements from baseline in HbA1c, FPG, body weight and SBP through week 104. Ertugliflozin was well tolerated, with non-clinically relevant changes in BMD. Compared with placebo/glimepiride, ertugliflozin increased female GMIs, but reduced the incidence of symptomatic hypoglycaemia. ClinicalTrials.gov Identifier: NCT02033889.

Design and baseline characteristics of the eValuation of ERTugliflozin effIcacy and Safety CardioVascular outcomes trial (VERTIS-CV).

BACKGROUND: Ertugliflozin is an inhibitor of sodium-glucose co-transporter-2 (SGLT2), approved in the United States and European Union to improve glycemic control in adults with type 2 diabetes mellitus (T2DM). The VERTIS cardiovascular (CV) outcomes trial (NCT01986881) has a primary objective to demonstrate non-inferiority of ertugliflozin versus placebo on major adverse CV events: time to the first event of CV death, nonfatal myocardial infarction, or nonfatal stroke. Secondary objectives are to demonstrate superiority of ertugliflozin versus placebo on time to: 1) the composite outcome of CV death or hospitalization for heart failure (HF); 2) CV death; and 3) the composite outcome of renal death, dialysis/transplant, or doubling of serum creatinine from baseline. METHODS: Patients ≥40 years old with T2DM (HbA1c 7.0-10.5%) and established atherosclerotic cardiovascular disease (ASCVD) of the coronary, cerebral, and/or peripheral arterial systems, were randomized 1:1:1 to once daily double-blind placebo, ertugliflozin 5 mg or 15 mg added to existing therapy. RESULTS: 8246 patients were randomized and 8238 received at least 1 dose of investigational product. Mean age was 64.4 years, 11.0% were ≥75 years old, and mean diabetes duration was 12.9 years with screening HbA1c of 8.3%. At entry, coronary artery disease, cerebrovascular disease, and peripheral arterial disease were present in 76.3%, 23.1%, and 18.8% of patients, respectively. HF was present in 23.1%, and Stage 3 kidney disease in 21.6% of patients. CONCLUSION: The results from the VERTIS-CV trial will define the CV and renal safety and efficacy of ertugliflozin in patients with T2DM and ASCVD.
