Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors exert hypoglycemic and diuretic effects by inhibiting the absorption of sodium and glucose from the proximal tubule. Currently available data indicate that SGLT2 inhibitors transiently enhance urinary sodium excretion and urinary volume. When combined with loop diuretics, SGLT2 inhibitors exert a synergistic natriuretic effect. The favorable diuretic profile of SGLT2 inhibitors may confer benefits to volume management in patients with heart failure but this natriuretic effect may not be the dominant mechanism for the superior long-term outcomes observed with these agents in patients with heart failure. The first part of this review explores the causes of transient natriuresis and the diuretic mechanisms of SGLT2 inhibitors. The second part provides an overview of the synergistic effects of combining SGLT2 inhibitors with loop diuretics, and the third part summarizes the mechanisms of cardiovascular protection associated with the diuretic effects of SGLT2 inhibitors.

Glucose-lowering Drugs and Hospitalization for Heart Failure: A Systematic Review and Additive-effects Network Meta-analysis With More Than 500 000 Patient-years. J Clin Endocrinol Metab 2021; 106:3060-3067.

Abstract
BACKGROUND Sodium glucose co-transporter 2 inhibitors (SGLT2is) prevent hospitalization resulting from heart failure (HHF). However, patients with type 2 diabetes mellitus use multiple antihyperglycemic drugs to achieve glycosylated hemoglobin (HbA1c) targets. In these drug combinations, the risk of HHF is unpredictable and so is the parallel effect of glucose-lowering. PURPOSE To examine the impact of antihyperglycemic drugs and their association on HHF. DATA SOURCES Forty randomized controlled trials (RCTs) reporting HHF. STUDY SELECTION Published RCTs were the data source. DATA EXTRACTION Incidence rates of HHF. DATA SYNTHESIS Random additive-effects network meta-analysis showed that metformin (P = 0.55), sulfonylureas (P = 0.51), glucagon-like peptide-1 receptor-agonist (P = 0.16), and dipeptidyl peptidase 4 inhibitors (DPP4is; P = 0.54) were neutral on the risk of HHF. SGLT2is and SGLT2is + DPP4is reduced the risk of HHF with a hazard ratio (HR) of 0.68 (95% CI, 0.60-0.76; P < 0.0001) and 0.70 (95% CI, 0.60-0.81; P < 0.0001), respectively. Increased risk of HHF was associated with thiazolidinediones (TZDs) as monotherapy or in combination with DPP4is (HR: 1.45; 95% CI, 1.18-1.78; P = 0.0004) and 1.49 (95% CI, 1.18-1.88; P = 0.0008), respectively. Regardless of the therapy, a 1% reduction in HbA1c reduced the risk of HHF by 31.3% (95% CI, 9-48; P = 0.009). LIMITATIONS There are no data to verify drug combinations available for clinical use and to discriminate the effect of drugs within each of the therapeutic classes. CONCLUSIONS The risk of HHF is reduced by SGLT2is as monotherapy or in combination with DPP4is and increased by TZDs as monotherapy or in combination. Glucose-lowering provides an additive effect of reducing HHF.

Obesity and effects of dapagliflozin on cardiovascular and renal outcomes in patients with type 2 diabetes mellitus in the DECLARE-TIMI 58 trial. Eur Heart J 2021; 43:2958-2967. [PMID: 34427295 DOI: 10.1093/eurheartj/ehab530] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 03/11/2021] [Accepted: 08/02/2021] [Indexed: 01/03/2023] Open
Abstract
AIMS We investigated the associations between obesity, cardiorenal events, and benefits of dapagliflozin in patients with type 2 diabetes mellitus (T2DM). METHODS AND RESULTS DECLARE-TIMI 58 randomized patients with T2DM and either atherosclerotic cardiovascular (CV) disease or multiple risk factors to dapagliflozin vs. placebo. Patients were stratified by body mass index (BMI, kg/m2): normal (18.5 to <25), overweight (25 to <30), moderately obese (30 to <35), severely obese (35 to <40), and very-severely obese (≥40). Outcomes analysed were CV death, hospitalization for heart failure (HHF), renal-specific composite outcome, and atrial fibrillation or flutter (AF/AFL). Of 17 134 patients, 9.0% had a normal BMI, 31.5% were overweight, 32.4% were moderately, 17.2% severely, and 9.8% were very-severely obese. Higher BMI was associated with a higher adjusted risk of HHF and AF/AFL (hazard ratio 1.30 and 1.28, respectively, per 5 kg/m2; P < 0.001 for all). Dapagliflozin reduced body weight by similar relative amounts consistently across BMI categories (percent difference: -1.9 to -2.4%). Although relative risk reductions in CV and renal-specific composite outcomes with dapagliflozin did not significantly differ across the range of BMI (P for interaction ≥0.20 for all outcomes), obese patients (BMI ≥ 30 kg/m2) tended to derive greater absolute risk reduction in HHF and AF/AFL (P for interaction 0.02 and 0.09, respectively) than non-obese patients. CONCLUSIONS In DECLARE-TIMI 58, patients with T2DM and higher BMI were more likely to have HHF and AF/AFL. Whereas relative risk reductions in CV and renal outcomes with dapagliflozin were generally consistent across the range of BMI, absolute risk reduction in obesity-related outcomes including HHF and AF/AFL tended to be larger in obese patients with T2DM.

Abstract
Patients with type 2 diabetes mellitus are at a higher risk of developing heart failure compared with the healthy population. In recent landmark clinical trials, sodium-glucose co-transporter 2 (SGLT2) inhibitor therapies improve blood glucose control and also reduce cardiovascular events and heart failure hospitalisations in patients with type 2 diabetes. Intriguingly, such clinical benefits have also been seen in patients with heart failure in the absence of type 2 diabetes although the underlying mechanisms are not clearly understood. Potential pathways include improved glycaemic control, diuresis, weight reduction and reduction in blood pressure, but none fully explain the observed improvements in clinical outcomes. More recently, novel mechanisms have been proposed to explain these benefits that include improved cardiomyocyte calcium handling, enhanced myocardial energetics, induced autophagy and reduced epicardial fat. We provide an up-to-date review of cardiac-specific SGLT2 inhibitor-mediated mechanisms and highlight studies currently underway investigating some of the proposed mechanisms of action in cardiovascular health and disease.

Abstract
AIM To evaluate the efficacy and safety of adjunct dapagliflozin therapy in patients with type 1 diabetes (T1D). MATERIALS AND METHODS DEPICT-1 and -2 were randomized, double-blind, parallel-group, 24-week studies, with 28-week extension periods. Adults with T1D and HbA1c 7.5%-10.5% were randomized (1:1:1) to receive dapagliflozin 5 mg, 10 mg or placebo. The short- and long-term efficacy and safety of dapagliflozin were examined in an exploratory pooled analysis of both studies. RESULTS Efficacy analyses included 530, 529 and 532 and safety analysis included 548, 566 and 532 patients in the dapagliflozin 5 mg, 10 mg and placebo groups, respectively. Baseline characteristics were similar between treatment groups. At week 24, reductions were seen with dapagliflozin 5 and 10 mg compared with placebo in HbA1c (-0.40%, -0.43% vs. 0.00%) and body weight (-2.45, -2.91 vs. 0.11 kg). HbA1c and body weight reductions versus placebo were also seen after 52 weeks of treatment. There was no imbalance in occurrence of severe hypoglycaemic events between groups. The proportion of patients experiencing definite diabetic ketoacidosis (DKA) was higher with dapagliflozin 5 mg (4.0%) and 10 mg (3.5%) compared with placebo (1.1%) over 52 weeks; most events were of mild or moderate severity, and all resolved with treatment. CONCLUSIONS Over 52 weeks, dapagliflozin provided glycaemic and weight benefits, with no increased frequency of severe hypoglycaemia compared with placebo. More DKA events were reported with dapagliflozin than placebo, highlighting the importance of appropriate patient selection, education and risk-mitigation strategies.

Abstract
AIMS/INTRODUCTION Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. METHODS This was an investigator-initiated multicenter prospective intervention study in which ipragliflozin (50 mg) was administered once daily, and glycemic control, estimated glomerular filtration rate (eGFR) and adverse events were evaluated until 104 weeks after starting research. RESULTS There were 407 patients analyzed. In the eGFR ≥90 group and eGFR ≥60 to <90 group, eGFR had significantly decreased compared with baseline at all time points from 4 to 104 weeks. There were significant increases in the eGFR ≥45 to <60 groups compared with baseline at 36 weeks (2.3 ± 1.0) and 52 weeks (2.6 ± 1.2). Comparison between the eGFR <60, urine albumin-to-creatinine ratio >300 group and the eGFR <60, urine albumin-to-creatinine ratio <300 group showed a greater reduction in eGFR in the former (-5.4 ± 2.4 vs 3.3 ± 1.1) at 12 weeks and was maintained to 104 weeks. In any group, eGFR did not significantly decrease until 104 weeks compared with 4 weeks. The urine albumin-to-creatinine ratio after 52 weeks and after 104 weeks was significantly decreased compared with baseline in the eGFR ≥90 group. CONCLUSIONS Ipragliflozin lowers eGFR and corrects hyperfiltration in patients with high eGFR (eGFR ≥60). In patients with low eGFR (eGFR ≥30 to <60), ipragliflozin has the possibility of increasing eGFR and exerting a renoprotective effect.

Abstract
AIMS Sodium glucose co-transporter 2 (SGLT2) inhibitors reduce several cardiovascular risk factors, including plasma glucose, blood pressure, albuminuria and body weight. Long-term treatment lowers risks of cardiovascular and renal events. The objective of this post hoc analysis was to determine the effects of canagliflozin treatment versus placebo on clinical outcomes in relation to body mass index (BMI). MATERIALS AND METHODS The CANVAS Program randomized 10 142 participants with type 2 diabetes to canagliflozin or placebo. These analyses tested the consistency of canagliflozin treatment effects across BMI levels for cardiovascular, renal, safety and body weight outcomes in three groups defined by baseline BMI: <25, 25-<30 and ≥30 kg/m2 . RESULTS In total, 10 128 participants with baseline BMI measurements were included. There were 966 participants with BMI <25 kg/m2 , 3153 with BMI 25-<30 kg/m2 and 6009 with BMI ≥30 kg/m2 . Mean percent body weight reduction with canagliflozin compared with placebo was greater at 12 months [-2.77% (95% confidence interval (CI): -2.95, -2.59)] than at 3 months [-1.72% (95% CI: -1.83, -1.62)]. The hazard ratios (HRs) for canagliflozin compared with placebo control for the composite outcome of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke were 1.03 (95% CI: 0.66, 1.59) in participants with BMI <25 kg/m2 , 0.97 (0.76, 1.23) with BMI 25-<30 kg/m2 and 0.79 (0.67, 0.93) with BMI ≥30 kg/m2 (P for heterogeneity = 0.55). The effects of canagliflozin on each component of the composite were also similar across BMI subgroups, as were effects on heart failure and renal outcomes (P for heterogeneity ≥0.19). The effects on safety outcomes were also broadly similar. CONCLUSIONS Canagliflozin improved cardiovascular and renal outcomes consistently across patients with a broad range of BMI levels.

Abstract
CONTEXT Sodium Glucose Co-Transporter-2 inhibitors (SGLT2i) are oral antidiabetic agents that can be used with insulin in the treatment of type 2 diabetes mellitus, known for cardiovascular and renal benefits. Dapagliflozin and empagliflozin are available in Turkey and we aimed to evaluate real-life data of using these two molecules with other oral antidiabetic drugs (OAD) or insulin. SUBJECTS AND METHODS 119 patients (59 women, 60 men) files who had started SGLT2i between 2017-2019 were examined retrospectively until 6 months after the treatment change. Patients' weight, body mass index (BMI), insulin doses, fasting blood glucose, HbA1c, lipid profile, spot urine albumin/creatinine ratio, e-GFR values, ALT, AST, uric acid levels were evaluated at baseline, 3 months and 6 months. RESULTS 41.2% of patients were using dapagliflozin and 58.8% were using empagliflozin. After 6 months of follow-up, HbA1c decreased from 8.27% to 7.45% (p<0.001). Daily total insulin dose decreased from 84.75 to 75.58 U/day in 3 months (p<0.004). Weight and BMI decreased significantly at 6 months. ALT, AST decreased significantly in patients using insulin (p 0.001 and 0.007), whereas spot urine microalbumin/creatinine ratio decreased at 3 and 6 months (p 0.005 and 0.020). A significant decrease was also observed in uric acid levels (p: 0.026). CONCLUSIONS Dapagliflozin and empagliflozin have beneficial effects on decreasing glycemic parameters, weight, transaminases, uric acid and microalbuminuria in the real life environment. We also observed that SGLT2i and insulin combination is as safe and effective as combination with OAD.

Abstract
: The prevalence of type 2 diabetes (T2D) has increased over the past few decades. T2D has a strong genetic propensity that becomes overt when a patient is exposed to a typical Western lifestyle, gain weight and becomes obese, whereas weight loss protects from the development of T2D. Except of lifestyle modifications, the choice of the appropriate treatment is essential in the management of patients with T2D and appears critical for the obese population with T2D. The new pharmacological approach for the treatment of T2D, sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists, seems to be effective not only in the management of T2D but also for weight loss, reduction of blood pressure and improvement of nonalcoholic fatty liver disease. Sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 analogues reduced cardiovascular risk, prevented cardiovascular disease and mortality, thereby playing an important role in the treatment of obese patients with hypertension and T2D.

Abstract
Background: The efficacy and safety of SGLT-2 and DPP-4 inhibitor monotherapies in T2DM is well established; however, data on the effect of combination therapies and sequence of administration are lacking. We investigated the efficacy and safety of the sequence of SGLT-2 and DPP-4 inhibitor administration in Japanese T2DM patients.Research design and methods: In this single-institution, open-label, randomized controlled study, T2DM patients inadequately controlled (HbA1c ≥6.5%) with conventional therapy were randomized to receive luseogliflozin-sitagliptin (LS; luseogliflozin 2.5 mg for 0-12 weeks, then luseogliflozin plus sitagliptin 50 mg for 12-24 weeks) or sitagliptin-luseogliflozin (SL; sitagliptin 50 mg for 0-12 weeks, then sitagliptin plus luseogliflozin 2.5 mg for 12-24 weeks). The main outcome was the difference in mean change in HbA1c at 24 weeks relative to baseline between both groups.Results: Of the 41 enrolled and randomized patients, 34 completed the study. Mean ± SD HbA1c at baseline was 10.35 ± 1.04% and 10.02 ± 1.40% in the LS and SL groups, respectively, and mean ± SD change in HbA1c at 24 weeks from baseline was -3.81 ± 1.21% vs -2.46 ± 1.42% (P < 0.01), respectively. No drug-related adverse events were reported.Conclusion: Over the 24-week period, LS was more effective in reducing HbA1c levels than SL in Japanese T2DM patients.

Abstract
We aimed to investigate the clinical factors affecting the therapeutic effectiveness of the sodium–glucose cotransporter-2 inhibitor empagliflozin in patients with type 2 diabetes mellitus (T2DM). We reviewed the medical records of 374 T2DM patients aged between 20 and 75 years who were prescribed empagliflozin 10 mg or 25 mg as add-on therapy for more than 90 consecutive days. Changes in hemoglobin A1c (HbA1c) from baseline levels and the reduction in body weights of the study participants were assessed. We found that younger patients (≤ 50 years), patients with the highest levels of HbA1c (>9%) at baseline, patients with an estimated glomerular filtration rate (eGFR) of >90 mL/min/1.73 m2, and patients with a shorter duration of T2DM (< 10 years) were more likely to exhibit a better glycemic response. Multivariate linear regression analysis revealed that a shorter duration of T2DM, higher baseline levels of HbA1c, and higher eGFR were positively associated with HbA1c reduction. Higher BMI and lower HbA1c levels were predictors of a more significant reduction in body weight among patients taking empagliflozin. The glucose-lowering effect of empagliflozin was more evident in T2DM patients with higher baseline HbA1c levels, better renal function, and shorter duration of T2DM.

Abstract
OBJECTIVE This study summarizes the evidence from randomized controlled trials (RCTs) to assess the effects of SGLT2 inhibitors on renal function and albuminuria in patients with type 2 diabetes. MATERIALS/METHODS We searched PubMed, Web of Science, Cochrane Library and EMBASE for reports published up to March 2018 and included RCTs reporting estimated glomerular filtration rate (eGFR) and/or urine albumin/creatinine ratio (UACR) changes. Data extraction and assessment of research quality based on Cochrane risk biasing tools. Data were calculated to represent the standardized mean difference (SMD) for each study, and the SMDs with 95% confidence intervals (CIs) were pooled using a random effects model. RESULTS Fifty-one studies were included that evaluated eGFR levels, and 17 studies were included that evaluated UACR levels. A meta-analysis showed that SGLT2 inhibitors had no significant effect on eGFR levels (SMD - 0.02, 95% CI - 0.06, 0.03, p = 0.45), and eGFR reduction was observed in the subsets of the duration of the trial 12 < duration ≤ 26 weeks (SMD - 0.08, 95% CI - 0.13, - 0.02, p = 0.005) and mean baseline eGFR < 60 ml/min per 1.73 square meters (SMD - 0.22, 95% CI - 0.37, - 0.07, p = 0.004). We found that SGLT2 inhibitors reduced UACR levels in patients with type 2 diabetes (SMD - 0.11, 95% CI - 0.17, - 0.05, p = 0.0001). Compared with monotherapy, the combination with other hypoglycemic agents can reduce albuminuria levels (SMD - 0.13, 95% CI - 0.19, - 0.06, p < 0.0001). CONCLUSIONS The effect of SGLT2 inhibitor on eGFR in patients with T2DM was not statistically significant, but it was effective in reducing albuminuria levels.

Abstract
BACKGROUND We aimed to retrospectively analyze the efficacy of 10 mg dapagliflozin (DAPA), which is a sodium-glucose cotransporter-2 inhibitor, in Korean patients with type 2 diabetes who visited a primary diabetes clinic. METHODS In total, 83 patients with type 2 diabetes, who received treatment with DAPA for the first time in a primary diabetes clinic between January 2015 and October 2015, were included in the study. The effect of DAPA in lowering glycosylated hemoglobin (HbA1c) levels was evaluated via chart review at 6 months follow-up. The patients were categorized into five groups according to add-on to or switched from other glucose-lowering agents: add-on to metformin (MET, n=10), add-on to MET+dipeptidyl peptidase 4 inhibitor (DPP4i, n=12), switched from sulfonylurea (SU, n=13), switched from DPP4i (n=11), and switched from thiazolidinedione (TZD, n=37). All the participants had already used MET for their regimen. RESULTS Treatment with DAPA reduced HbA1c level by 1.2%±0.8%. Moreover, a significant decrease was observed in all subgroups: add-on to MET, -1.2%±0.7%; add-on to MET+DPP4i, -1.4%±0.8%; switched from SU, -1.4%±0.7%; switched from DPP4i, -0.5%±0.7%; and switched from TZD, -1.2%±0.9% (P<0.01). A significant decrease in body weight (-3.1±2.6 kg, P<0.001) was observed after DAPA administration. Estimated glomerular filtration rate and urine microalbumin were significantly decreased after 6 months of treatment with DAPA (-4.0±13.5 mL/min/1.73 m², P=0.03; -23.6±45.9 mg/L, P<0.001). CONCLUSION Treatment with DAPA, whether added to or switched from other glucose-lowering agents, significantly decreased HbA1c levels in Korean patients with type 2 diabetes who visited a single primary diabetes clinic. DAPA can be considered as an optimal second-line treatment for patients with type 2 diabetes, as supported by real-world evidence studies.

Abstract
With their novel, insulin-independent mechanism, sodium-glucose cotransporter-2 (SGLT2) inhibitors are a major turning point in the management of type 2 diabetes mellitus. At present, there are several SGLT2 inhibitors available or in development, and these oral anti-hyperglycaemic agents lower plasma glucose through the inhibition of SGLT2-mediated reuptake of filtered glucose in the kidney. This unique mechanism of action is also expected to result in other beneficial effects, such as weight loss and blood pressure reduction. In various studies, including randomized controlled trials and real-world studies, patients treated with SGLT2 inhibitors have reported weight loss of around 1 to 3 kg. This review describes the characteristics of weight loss associated with SGLT2 inhibitor therapy, the clinical factors affecting SGLT2 inhibitor-associated weight loss and the possible underlying mechanisms of SGLT2 inhibitor-associated weight loss, including changes in metabolism and body composition, and the role of a reduction in insulin dose and compensatory hyperphagia. Understanding the weight loss effect of SGLT2 inhibitors, its related factors and underlying mechanisms can aid clinicians in optimal treatment decision-making, provide valuable insight on both obesity and diabetes management and reveal areas of future research and new therapeutic options.

Abstract
In the present randomized study, we assessed the efficacy of ipragliflozin compared with sitagliptin in 124 Japanese patients with type 2 diabetes. Sodium-glucose co-transporter-2 inhibitor-naïve and incretin-related agent-naïve patients were randomly assigned to receive additional 50 mg ipragliflozin or sitagliptin. The primary endpoint was the proportion of participants with >0.5% decrease in glycated haemoglobin (HbA1c) without body weight gain at 12 weeks. For secondary endpoints, we measured several biomarkers related to metabolic changes. After 12 weeks, 53.9% of participants in the ipragliflozin and 42.9% in the sitagliptin group reached the primary endpoint (P = 0.32). Decreases in homeostatic model assessment of insulin resistance, body fat percentage and skeletal muscle mass index, and increases in free fatty acids, ketone body concentration and HDL cholesterol levels were greater in the ipragliflozin group. Increases in homeostatic model assessment of β-cell function and decreases in proinsulin-to-insulin ratio were greater in the sitagliptin group. No serious adverse events occurred in either group. In conclusion, ipragliflozin had beneficial effects on fat reduction, insulin resistance and lipid metabolism, while sitagliptin had beneficial effects on β-cell function.

Abstract
Background In our previous study, we investigated the efficacy of ipragliflozin, a sodium-glucose cotransporter (SGLT) 2 inhibitor on diabetic nephropathy in patients with type 2 diabetes and demonstrated that ipragliflozin significantly improved diabetic nephropathy in addition to reducing HbA1c and body weight. Herein, we conducted post-trial monitoring to determine whether these lowering effects on blood glucose and body weight or the beneficial effects on diabetic nephropathy were maintained long-term (104 weeks) after starting ipragliflozin treatment. Methods Initially, during a 24-week interventional trial period, a 50 mg dose of ipragliflozin was administered to 50 patients with type 2 diabetes without changing other treatments. During the post-trial monitoring period, these patients returned to hospital-based diabetes care according to their clinical needs. We continued monitoring their clinical data for 104 weeks in each hospital and analyzed the results on an intention-to-treat basis. Results The improvements in glycemic control and body weight reduction provided by 24-week ipragliflozin administration were maintained for 104 weeks. Despite a transient decrease during the intervention period, the estimated glomerular filtration rate (eGFR) was restored to near the baseline level at 104 weeks. Notably, in patients with diabetic nephropathy, the median urinary albumin-to-creatinine ratio (UACR) was significantly decreased from 119.2 (98.9 - 201.8) at baseline to 36.9 (19.7 - 204.7) mg/gCr at 104 weeks. In addition, eGFR was stable for 104 weeks, showing no decrease. In contrast, a significant positive correlation between UACR and blood pressure observed at 24 weeks disappeared after discontinuation of the intervention therapy. Conclusions The well-controlled HbA1c and body weight reductions were maintained for 104 weeks of post-trial follow-up. Moreover, ipragliflozin significantly reduced urinary albumin excretion in patients with diabetic nephropathy without decreasing eGFR.

Diabetes Obes Metab 2018; 20:1520-1525.

Abstract
This analysis assessed whether responses with exenatide once weekly plus dapagliflozin (n = 231), exenatide once weekly alone (n = 230), or dapagliflozin alone (n = 233) differed in key patient subpopulations of the DURATION-8 trial. Potential treatment-by-subgroup interactions for changes in glycated haemoglobin (HbA1c) and body weight after 28 weeks were evaluated among subgroups determined by baseline HbA1c, age, sex, body mass index, type 2 diabetes duration, race, ethnicity and estimated glomerular filtration rate (eGFR). Exenatide once weekly plus dapagliflozin reduced HbA1c and body weight across all subgroups: least-squares mean reductions ranged from -8.4 to -26.1 mmol/mol (-0.77% to -2.39%) for HbA1c and from -2.07 to -4.55 kg for body weight. Potential treatment-by-subgroup interactions (P < .10) were found for HbA1c change by age (P = .016) and eGFR (P = .097). Age subgroup analysis findings were not consistent with expected mechanistic effects, with the small number of patients aged ≥65 years (n = 74 vs n = 499 for patients aged <65 years) limiting the interpretability of the interaction term. In the exenatide once weekly plus dapagliflozin and dapagliflozin groups, but not the exenatide once weekly group, HbA1c reductions were greater among patients with eGFR ≥90 vs ≥60 to <90 mL/min/1.73 m2 (least-squares mean reductions of -23.6 vs -19.0 mmol/mol [-2.16% vs -1.74%], -17.3 vs -12.0 mmol/mol [-1.58% vs -1.10%], and -17.7 vs -16.9 mmol/mol [-1.62% vs -1.55%] for the respective treatments); this was consistent with the mechanism of action of dapagliflozin. A potential treatment-by-subgroup interaction was observed for change in body weight by sex (P = .099), with greater weight loss for women vs men across all treatments (range -2.56 to -3.98 kg vs -0.56 to -2.99 kg). In conclusion, treatment with exenatide once weekly plus dapagliflozin reduced HbA1c and body weight across all patient subgroups and was more effective than exenatide once weekly or dapagliflozin alone in all adequately sized subgroups.

Abstract
INTRODUCTION Predictors for the effect of sodium glucose co-transporter 2 (SGLT2) inhibitors at lowering hemoglobin A1c (HbA1c) levels in type 2 diabetes mellitus patients remain unclear. We therefore aimed to elucidate these predictors in type 2 diabetes patients after 3 months of SGLT2 treatment. METHODS A total of 302 consecutive type 2 diabetes patients who had been treated with SGLT2 inhibitors as monotherapy or add-on therapy to existing antidiabetic treatments were enrolled retrospectively. After excluding 27 patients whose HbA1c levels could not be evaluated 3 months after treatment, the glucose-lowering effects of SGLT2 inhibitors were assessed in 275 patients by measuring HbA1c levels before and 3 months after treatment. The predictors for changes in HbA1c levels after 3 months of treatment were evaluated. RESULTS SGLT2 inhibitor treatment for 3 months decreased HbA1c levels from 7.8 ± 1.2% to 7.4 ± 1.0% (p < 0.0001). A multiple regression analysis showed that the independent determinants for SGLT2 inhibitor treatment effect included decreased HbA1c levels after 1 month of treatment, high baseline HbA1c levels, and a high estimated glomerular filtration rate (eGFR). CONCLUSION We show that type 2 diabetes patients who received the greatest glucose-lowering effect with SGLT2 inhibitor treatment were those with preserved renal function (high baseline eGFR) and high baseline HbA1c levels. Moreover, SGLT2 inhibitor treatment efficacy could be predicted by the patients' initial response to treatment.

Time-dependent effects of ipragliflozin on behaviour and energy homeostasis in normal and type 2 diabetic rats: continuous glucose telemetry analysis. Sci Rep 2017; 7:11906. [PMID: 28928461 PMCID: PMC5605532 DOI: 10.1038/s41598-017-12106-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2016] [Accepted: 09/04/2017] [Indexed: 01/03/2023] Open
Abstract
Sodium–glucose cotransporter 2 (SGLT2) inhibitors are oral antidiabetic drugs that promote urinary glucose excretion. Conversely, they cause behavioural changes, such as hyperphagia, that result in a positive energy balance. The relationship between energy homeostasis and SGLT2 inhibitors-induced behavioural changes remains unclear. Here we show that ipragliflozin, a SGLT2 inhibitor, time-dependently affects behaviour and enhances energy expenditure in normal and type 2 diabetic Goto–Kakizaki (GK) rats, using continuous glucose telemetry. Alongside increased urinary glucose excretion, ipragliflozin increased total food and water intakes in normal and GK rats. In normal rats, ipragliflozin treatment acutely disturbed the circadian rhythms of food and water intakes, activity, and body temperature. Subsequently, these rhythms gradually returned towards a normal state. However, activity and body temperature remained suppressed. In GK rats, ipragliflozin did not affect circadian rhythms. Blood glucose values assessed by glucose telemetry were significantly reduced in both ipragliflozin-treated groups. Despite these behavioural and glycaemic changes, ipragliflozin significantly increased oxygen consumption during dark and light periods in both groups. Ipragliflozin reduced body weight in normal rats only. Thus, ipragliflozin decreases blood glucose beyond compensatory hyperphagia in normal and GK rats, resulting in enhanced basal energy expenditure, despite acutely altering circadian rhythms in normoglycaemic individuals.

Effectiveness of Ipragliflozin for Reducing Hemoglobin A1c in Patients With a Shorter Type 2 Diabetes Duration: Interim Report of the ASSIGN-K Study. J Clin Med Res 2017; 9:793-801. [PMID: 28811858 PMCID: PMC5544486 DOI: 10.14740/jocmr3116w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2017] [Accepted: 06/13/2017] [Indexed: 01/01/2023] Open
Abstract
Background Ipragliflozin is a selective sodium glucose co-transporter 2 inhibitor. The ASSIGN-K study is investigating the efficacy and safety of ipragliflozin for type 2 diabetes mellitus (T2DM) in the real-world clinical setting. Methods Japanese T2DM patients with inadequate glycemic control despite diet and exercise with/without pharmacotherapy were enrolled in an investigator-driven, multicenter, prospective, observational study examining the efficacy and safety of ipragliflozin treatment (50 mg/day for 52 weeks). We performed interim analysis after 24 weeks. Results In 367 patients completing 24-week ipragliflozin therapy, hemoglobin A1c (HbA1c) decreased significantly from 8.07% at baseline to 7.26% in week 24 (P < 0.001). The change in HbA1c from treatment initiation to week 24 was -0.88% in patients < 65 years old versus -0.55% in those ≥ 65 years and -0.92% in men versus -0.70% in women (all P < 0.001). When baseline HbA1c was < 7%, 7% to < 8%, and ≥ 8%, the change was -0.18%, -0.45%, and -1.48%, respectively (P = 0.5352, P < 0.001, and P < 0.001, respectively). When baseline body mass index (BMI) was < 25, 25 to < 30, and ≥ 30, the change was -1.05%, -0.65%, and -0.87%, respectively (all P < 0.001). Multiple regression analysis showed that HbA1c decreased more in patients with a higher baseline HbA1c or shorter duration of diabetes. An HbA1c < 7% was achieved in 33.3% of the patients, and their baseline HbA1c was significantly lower than that of patients failing to achieve it (P < 0.001). Adverse events (AEs) occurred in 106/451 patients (23.5%), including 29.1% of patients aged 65 or older. Common AEs were vulvovaginal candidiasis (3.1%) and genital pruritus (1.8%). Serious AEs included urinary tract infection, unstable angina, and ketosis, which occurred in patients who did not suspend medication during acute illness. Conclusions Ipragliflozin significantly improved HbA1c in T2DM patients with inadequate glycemic control. Improvement in HbA1c was significant irrespective of age, sex, baseline HbA1c, or BMI, but efficacy was greater with a higher baseline HbA1c and shorter duration of diabetes. For safe continuation of treatment, patients should be advised to suspend medication during acute illness.

Abstract
BACKGROUND Ipragliflozin, a sodium-glucose transporter 2 inhibitor, was administered to patients with type 2 diabetes mellitus for 24 weeks to evaluate its effect on glycemic control and body composition. METHODS This was an investigator-initiated multicenter prospective intervention study in which ipragliflozin (50 mg) was administered once daily and glycemic control, blood pressure, body weight (BW), body composition (measured by a biological impedance method), the lipid profile, and adverse events were evaluated after 4, 12, and 24 weeks of treatment. RESULTS Efficacy and safety up to 24 weeks of ipragliflozin therapy were analyzed in 367 patients and 451 patients, respectively. Hemoglobin A1c decreased significantly from 8.07% at the start of ipragliflozin therapy to 7.26% in week 24 (P < 0.001). Fasting and postprandial blood glucose levels were significantly reduced by ipragliflozin. In week 24, there were significant decreases from baseline in BW (-2.6 kg), waist circumference (-2.9 cm), and body fat mass (-1.9 kg) (P < 0.001). The body water mass and mineral mass were decreased significantly by 0.5 and by 0.1 kg, respectively (P < 0.001), whereas the protein mass did not change significantly. Intracellular water mass did not change significantly, whereas extracellular water mass showed a significant decrease of 0.5 kg (P < 0.001). Muscle mass did not change in the upper and lower limbs, but that of the trunk decreased significantly (P < 0.001). There was a significant decrease in the fasting triglyceride level and a significant increase in fasting high-density lipoprotein cholesterol level, while low-density lipoprotein cholesterol was unchanged. Adverse events occurred in 23.5% of the patients, with a high frequency of genital infections, such as vulvovaginal candidiasis (3.1%) and genital pruritus (1.8%). Adverse drug reactions were noted in 13.7% of the patients. CONCLUSIONS Administration of ipragliflozin for 24 weeks improved glycemic control and decreased BW. Reduction of body fat accounted for more than 70% of the total weight loss and reduction of extracellular water accounted for about 20%.

Abstract
Background Sodium-glucose cotransporter 2 (SGLT2) inhibitors are novel agents used to treat type 2 diabetic patients. We investigated the efficacy of the SGLT2 inhibitor ipragliflozin on diabetic nephropathy in Japanese patients with type 2 diabetes. Methods A 50 mg dose of ipragliflozin was administered for 24 weeks to 50 patients with type 2 diabetes who were concomitantly managed with diet and exercise therapy alone or antidiabetic medications other than SGLT2 inhibitors. Results At the end of the 24-week ipragliflozin treatment, significant decreases in mean glycated hemoglobin (HbA1c) (1.0±1.2%) and body weight (2.7 ± 2.5 kg) were observed; in addition, median urinary albumin-to-creatinine ratio (UACR) significantly decreased from 15.5 (8.0 - 85.7) to 12.9 (7.4 - 36.3) mg/gCr. Sub-analysis by renal function at baseline revealed that median UACR in patients with estimated glomerular filtration rate (eGFR) ≥ 90 mL/min/1.73 m2 decreased significantly from 12.3 (7.5 - 89.6) to 10.6 (5.8 - 27.3) mg/gCr. Furthermore, mean eGFR decreased significantly from 102.4 ± 8.6 to 93.6 ± 10.5 mL/min/1.73 m2 in these patients. In contrast, UACR and eGFR did not change significantly in patients with eGFR < 90. In addition, analysis of the relationship between the amount of change in UACR and blood pressure at 24 weeks revealed a significant positive correlation between UACR and SBP values, independently of the presence of diabetic nephropathy. Conclusions Our results indicate that ipragliflozin may facilitate HbA1c control and body weight reduction. Furthermore, our results also raise the possibility that ipragliflozin significantly reduces urinary albumin levels and improves glomerular hyperfiltration in a subset of patients with type 2 diabetes.
