A 52-week efficacy and safety study of enavogliflozin versus dapagliflozin as an add-on to metformin in patients with type 2 diabetes mellitus: ENHANCE-M extension study.

AIM: To evaluate the long-term safety and efficacy of enavogliflozin 0.3 mg/day added to metformin in patients with type 2 diabetes mellitus. MATERIALS AND METHODS: After 24 weeks of a randomized, double-blind treatment period with enavogliflozin 0.3 mg/day (n = 101) or dapagliflozin 10 mg/day (n = 99) added to metformin, all patients received enavogliflozin 0.3 mg/day plus metformin for an additional 28 weeks during the open-label extension period. RESULTS: Eighty-two patients continued enavogliflozin (maintenance group), and 77 were switched from dapagliflozin to enavogliflozin (switch group). All adverse drug reactions (ADR) were mild in severity. In the maintenance group, ADRs (cystitis and vaginal infection) were reported in two patients (2.44%) during 52 weeks. In the switch group, ADR (hypoglycaemia) was reported in one patient (1.30%) during a 28-week open-label extension period. At week 52, glycated haemoglobin and fasting plasma glucose were significantly lower than at the baseline, by 0.85% and 29.08 mg/dl, respectively, in the maintenance group (p < .0001 for both), and by 0.81% and 32.77 mg/dl, respectively, in the switch group (p < .0001 for both). At week 52, 68.92% of patients from the maintenance group and 64.29% from the switch group achieved glycated haemoglobin <7%. A significant increase in the urine glucose-creatinine ratio was observed at week 52, by 58.81 g/g and 63.77 g/g in the maintenance and switch groups, respectively (p < .0001). CONCLUSIONS: Enavogliflozin added to metformin was tolerated well for up to 52 weeks and provided continual glycaemic control in type 2 diabetes mellitus, along with a significant increase in the urine glucose-creatinine ratio.

Relevance of GLP-1 receptor agonists or SGLT-2 inhibitors on the recruitment for clinical studies in patients with NAFLD.

INTRODUCTION: Guidelines increasingly recommend the use of glucagon-like peptide-1 receptor agonists (GLP-1 RA) or sodium-glucose co-transporter-2 inhibitors (SGLT2i) to prevent cardiovascular and cardiorenal endpoints. Both drugs also show beneficial effects in nonalcoholic fatty liver disease (NAFLD). Preexisting GLP-1 RA and SGLT2i therapies are frequently defined as exclusion criterion in clinical studies to avoid confounding effects. We therefore investigated how this might limit recruitment and design of NAFLD studies. METHODS: GLP-1 RA and SGLT2i prescriptions were analyzed in NAFLD patients with diabetes mellitus recruited at a tertiary referral center and from the population-based LIFE-Adult-Study. Individuals were stratified according to noninvasive parameters of liver fibrosis based on vibration-controlled transient elastography (VCTE). RESULTS: 97 individuals were recruited at tertiary care and 473 from the LIFE-Adult-Study. VCTE was available in 97/97 and 147/473 cases.GLP-1 RA or SGLT2i were used in 11.9% of the population-based cohort (LSM < 8 kPa), but in 32.0% with LSM ≥ 8 kPa. In the tertiary clinic, it was 30.9% overall, independent of LSM, and 36.8% in patients with medium and high risk for fibrotic NASH (FAST score > 0.35). At baseline, 3.1% of the patients in tertiary care were taking GLP-1 RA and 4.1% SGLT2i. Four years later, the numbers had increased to 15.5% and 21.6%. CONCLUSION: GLP-1 RA and SGLT2i are frequently and increasingly prescribed. In candidates for liver biopsy for NASH studies (VCTE ≥ 8 kPa) the use of them exceeds 30%, which needs careful consideration when designing NASH trials.

Empagliflozin Enhances Autophagy, Mitochondrial Biogenesis, and Antioxidant Defense and Ameliorates Renal Ischemia/Reperfusion in Nondiabetic Rats.

BACKGROUND: Recent meta-analyses have shown that sodium-glucose cotransporter 2 (SGLT-2) inhibitors alleviate chronic kidney disease and acute kidney injury in diabetic patients. In this study, we aimed to investigate the effect of empagliflozin on renal ischemia/reperfusion (I/R) in nondiabetic rats and find the possible mechanisms. Experimental Approach. Eighteen male Wistar rats were randomly divided into three groups, including healthy control, ischemic control, and empagliflozin-treated group. Thirty minutes of bilateral renal ischemia was induced by clamping the renal hilum. Forty-eight hours after reopening the clamps, rats' blood samples and tissue specimens were collected. Empagliflozin 10 mg/kg was administered by gavage, 2 hours before ischemia and 24 hours after the first dose. RESULTS: I/R injury led to a significant rise in serum creatinine and blood urea nitrogen which was significantly decreased after treatment with empagliflozin. Empagliflozin also alleviated tubulointerstitial and glomerular damage and significantly decreased tissue histology scores. Empagliflozin decreased the increased levels of malondialdehyde, interleukin 1ß, and tumor necrosis factor α. SGLT2 inhibition increased the decreased expression of nuclear factor erythroid 2-related factor 2 and PPARG coactivator 1 alpha that conduct antioxidant defense and mitochondrial biogenesis, respectively. Furthermore, empagliflozin markedly increased LC3-II/LC3-I and bcl2/bax ratios, showing its beneficial effect on activation of autophagy and inhibition of apoptosis. Despite its effects on diabetic nephropathy, empagliflozin did not activate the Sestrin2/AMP-activated protein kinase pathway in this study. CONCLUSION: Empagliflozin improved renal I/R injury in nondiabetic rats in this study by promoting autophagy and mitochondrial biogenesis and attenuation of oxidative stress, inflammation, and apoptosis.

Dapagliflozin Ameliorates the Formation and Progression of Experimental Abdominal Aortic Aneurysms by Reducing Aortic Inflammation in Mice.

BACKGROUND: Dapagliflozin, a sodium glucose transporter protein-2 (SGLT-2) inhibitor, reduces the risk for cardiovascular diseases. However, the influence of dapagliflozin on nondissecting abdominal aortic aneurysms (AAAs) remains unclear. METHODS: AAAs were created in male C57BL/6 mice via intra-aortic porcine pancreatic elastase (PPE) infusion. Mice were daily treated with dapagliflozin (1 or 5 mg/kg body weight) or an equal volume of vehicle through oral gavage beginning one day prior to PPE infusion for 14 days. To investigate its translational value, dapagliflozin or vehicle was also administered to mice with existing AAAs in another cohort. Aortic diameters were measured prior to (day 0 for baseline) and 14 days after PPE infusion. After sacrifice, mice aortae were collected, and following histological analyses were performed. RESULTS: Dapagliflozin treatment significantly reduced aneurysmal aortic expansion following PPE infusion as compared to vehicle treatment especially at 5 mg/kg body weight (approximately 21% and 33% decreases in 1 and 5 mg/kg treatment groups, respectively). The dose-dependent attenuation of AAAs by dapagliflozin was also confirmed on histological analyses. Dapagliflozin remarkably reduced aortic accumulation of macrophages, CD4+ T cells, and B cells particularly following dapagliflozin treatment at 5 mg/kg. Dapagliflozin treatment also markedly attenuated medial SMC loss. Though the difference was not significant, dapagliflozin treatment tended to attenuate CD8+ T cells and elastin degradation. Dapagliflozin treatment at 5 mg/kg caused a 53% reduction in neovessel density. Furthermore, dapagliflozin treatment mitigated further progress of existing AAAs. CONCLUSION: Dapagliflozin treatment ameliorated PPE-induced AAAs by inhibiting aortic leukocytes infiltration and angiogenesis.

Antifibrotic effects of low dose SGLT2 Inhibition with empagliflozin in comparison to Ang II receptor blockade with telmisartan in 5/6 nephrectomised rats on high salt diet.

To date, the lowest protective SGLT2 inhibitor dose is unknown. We initially performed a dose-response pilot study in normal rats. Based on the results of this pilot study we compared the cardio-renal effects of the SGLT-2 inhibitor empagliflozin, with placebo or telmisartan in rats with 5/6 nephrectomy (5/6 Nx) on a high salt diet (HSD). The experimental set up was as follows: Sham operation (Sham) with normal diet and placebo; 5/6 Nx with 2% HSD and placebo; 5/6 Nx with HSD and empagliflozin (0.6 mg/kg/day, bid); 5/6 Nx with HSD and telmisartan (5 mg/kg/day, qd). Empagliflozin treatment increased urinary glucose excretion, in parallel to empagliflozin plasma levels, in a dose-dependent manner starting at doses of 1 mg/kg in the pilot study. 5/6Nx rats on HSD treated with this low empagliflozin dose showed significantly reduced cardiac (-34.85%; P < 0.05) and renal (-33.68%; P < 0.05) fibrosis in comparison to 5/6Nx rats on HSD treated with placebo. These effects were comparable to the effects observed when implementing the standard dose (5 mg/kg/day) of telmisartan (cardiac fibrosis: -36.37%; P < 0.01; renal fibrosis; -43.96%; P < 0.01). RNA-sequencing followed by confirmatory qRT-PCR revealed that both telmisartan and empagliflozin exert their cardiac effects on genes involved in vascular cell stability and cardiac iron homeostasis, whereas in the kidneys expression of genes involved in endothelial function and oxidative stress were differentially expressed. Urinary adenosine excretion, a surrogate marker of the tubuloglomerular feedback (TGF) mechanism, was not affected. In conclusion, the antifibrotic properties of low dose empagliflozin were comparable to a standard dose of telmisartan. The underlying pathways appear to be TGF independent.

Ação dos isglt2 no hipertenso diabético, quando indicar? / Effect of sglt-2 inhibitor in diabetic hypertensive patients, when to indicate?

A doença cardiovascular (DCV) representa um fardo individual e social em pacientes com diabetes mellitus tipo 2 (DM2). A diabetes é uma doença crônica onerosa do ponto de vista social e econômico. O seu tratamento inclui medidas não farmacológicas, como dieta e exercício físico, bem como a adição de medicamentos em pacientes que não atingem controle glicêmico satisfatório através de medidas comportamentais. Medicamentos da classe inibidores de SGLT2 (iSGLT2), objeto deste manuscrito, têm sido associados com a redução de eventos cardiovasculares e mortalidade, além de redução da pressão arterial e peso, sem conferir aumento de risco de hipoglicemia

Cardiovascular disease (CVD) represents an individual and social burden in patients with type 2 diabetes mellitus (T2DM). Diabetes is a chronic, socially and economically costly disease. Its treatment includes non-pharmacological measures, such as diet and exercise, as well as the addition of medication in patients who do not achieve satisfactory glycemic control through behavioral approach. Drugs as SGLT2 inhibitor (SGLT2i), object of this manuscript, have been associated with a reduction in cardiovascular events and mortality, in addition to a reduction in blood pressure and weight, without increasing the risk of hypoglycemia.

Complex Positive Effects of SGLT-2 Inhibitor Empagliflozin in the Liver, Kidney and Adipose Tissue of Hereditary Hypertriglyceridemic Rats: Possible Contribution of Attenuation of Cell Senescence and Oxidative Stress.

(1) Background: empagliflozin, sodium-glucose co-transporter 2 (SGLT-2) inhibitor, is an effective antidiabetic agent with strong cardio- and nephroprotective properties. The mechanisms behind its cardio- and nephroprotection are still not fully clarified. (2) Methods: we used male hereditary hypertriglyceridemic (hHTG) rats, a non-obese model of dyslipidaemia, insulin resistance, and endothelial dysfunction fed standard diet with or without empagliflozin for six weeks to explore the molecular mechanisms of empagliflozin effects. Nuclear magnetic resonance (NMR)-based metabolomics; quantitative PCR of relevant genes involved in lipid and glucose metabolism, or senescence; glucose and palmitic acid oxidation in isolated tissues and cell lines of adipocytes and hepatocytes were used. (3) Results: empagliflozin inhibited weight gain and decreased adipose tissue weight, fasting blood glucose, and triglycerides and increased HDL-cholesterol. It also improved insulin sensitivity in white fat. NMR spectroscopy identified higher plasma concentrations of ketone bodies, ketogenic amino acid leucine and decreased levels of pyruvate and alanine. In the liver, adipose tissue and kidney, empagliflozin up-regulated expression of genes involved in gluconeogenesis and down-regulated expression of genes involved in lipogenesis along with reduction of markers of inflammation, oxidative stress and cell senescence. (4) Conclusion: multiple positive effects of empagliflozin, including reduced cell senescence and oxidative stress, could contribute to its long-term cardio- and nephroprotective actions.

Empagliflozin nanoparticles attenuates type2 diabetes induced cognitive impairment via oxidative stress and inflammatory pathway in high fructose diet induced hyperglycemic mice.

There is snowballing evidence that type 2 diabetes (T2D) predisposes to neuropathophysiological alterations including oxidative stress and triggered inflammatory responses in brain that eventually culminates into cognitive impairment.Accumulating evidences suggest that SGLT2 inhibitor can be a promising intervention for cognitive decline in T2DM. In the present paper, the potential effects of Empagliflozin (EMPA), a SGLT2 inhibitor, against T2D induced cognitive dysfunction have been explored. The effect of EMPA on array of inflammatory mediators including Interleukin-6(IL-6), Interleukin -1ß (IL-1ß), and Tumour necrosis factor-α(TNF-α)), neuronal proteins including glycogen synthase kinase-3ß (GSK- 3ß), Phosphorylated tau (p-tau), amyloid beta (Aß) (1-40, 1-42) and altered oxidative parameters including SOD, catalase, TBARS was determined in the high fructose diet induced hyperglycaemic mice. The obtained results were compared with EMPA nanoparticles (Nps) formulated in our laboratory and found that EMPA Nps significantly showed reduced levels of inflammatory mediators and oxidative stress. Further, decrease in levels of p-tau, Aß (1-40) and Aß (1-42) were also observed with EMPA nanoparticles.Thus, the study has demonstrated that EMPA Nps could be a promising therapy to alleviate the progression of cognitive decline in T2D.

Diabetes, Antidiabetic Medications and Cancer Risk in Type 2 Diabetes: Focus on SGLT-2 Inhibitors.

In the last decade, cancer became the leading cause of death in the population under 65 in the European Union. Diabetes is also considered as a factor increasing risk of cancer incidence and mortality. Type 2 diabetes is frequently associated with being overweight and obese, which also plays a role in malignancy. Among biological mechanisms linking diabetes and obesity with cancer hyperglycemia, hyperinsulinemia, insulin resistance, increased levels of growth factors, steroid and peptide hormones, oxidative stress and increased activity of pro-inflammatory cytokines are listed. Antidiabetic medications can modulate cancer risk through directly impacting metabolism of cancer cells as well as indirectly through impact on risk factors of malignancy. Some of them are considered beneficial (metformin and thiazolidinedions-with the exception of bladder cancer); on the other hand, excess of exogenous insulin may be potentially harmful, while other medications seem to have neutral impact on cancer risk. Inhibitors of the sodium-glucose cotransporter-2 (SGLT-2) are increasingly used in the treatment of type 2 diabetes. However, their association with cancer risk is unclear. The aim of this review was to analyze the anticancer potential of this class of drugs, as well as risks of site-specific malignancies associated with their use.

Glucose-dependent diuresis in relation to improvements in renal-tubular markers of sodium-glucose cotransporter-2 inhibitors in hospitalized heart failure patients with diabetes.

Clinical parameters with correlation to diuretic effects after initiation of sodium-glucose cotransporter-2 (SGLT2) inhibitors are unclear. We aimed to identify the factors associated with the diuretic effect observed following the initiation of SGLT2 inhibitors in patients with diabetes having an acute heart failure (HF). Fifty-six patients included were hospitalized for acute HF with diabetes and started on SGLT2 inhibitors. Changes in urine volume (ΔUV) and blood/urine laboratory parameters before and during the first 4 days of therapy were evaluated. Data were prospectively obtained under clinically stable conditions after initial HF treatment. UV increased following the initiation of SGLT2 inhibitors [UV at baseline (BL): 1383 ± 479 mL/day; ΔUV over 4 days: + 189 ± 358 mL/day]. Multivariate analysis revealed no association between BL-hemoglobin A1c or BL-estimated glomerular filtration rate and ΔUV. Conversely, higher BL-fasting plasma glucose (FPG) and higher BL-urine N-acetyl-ß-D-glucosaminidase (NAG) were associated with a higher ΔUV. ΔUV was inversely associated with ΔFPG and ΔNAG, and positively associated with Δurinary sodium excretion. Elevated FPG and NAG both improved over 4 days of treatment. In conclusion, the diuretic effect of SGLT2 inhibitors was glycemia-dependent, and was associated with a reduction in elevated renal-tubular markers in hospitalized HF complicated with diabetes.

Comparison of the Pharmacokinetic and Pharmacodynamic Relationship of Ipragliflozin Between Patients With Type 1 and Type 2 Diabetes Mellitus.

PURPOSE: To characterize the pharmacokinetic and pharmacodynamic (PK/PD) relationship of ipragliflozin in Japanese patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) and to determine the appropriate dose regimen for a Phase III study of ipragliflozin in Japanese patients with T1DM. METHODS: The PK (AUC24h of plasma ipragliflozin) and PD (renal glucose clearance) properties in patients with T1DM and T2DM were assessed in 2 independent clinical pharmacologic studies of ipragliflozin. The same maximum efficacy (Emax) model described the PK/PD relationship in patients with T1DM and T2DM. Changes in fasting plasma glucose (FPG) in T1DM patients were simulated by applying a previously established FPG model for ipragliflozin in patients with T2DM. FINDINGS: Data from 42 patients with T1DM and 28 patients with T2DM were used. Comparable AUC24h of plasma ipragliflozin and similar dose dependency were observed on day 14 between patients with T1DM and those with T2DM. Decreases in renal glucose clearance were comparable regardless of the ipragliflozin dose in both groups of patients. The estimated mean Emax and AUC24h producing 50% of Emax (EX50) were 45.1 mL/min (95% CI, 37.0-53.2 mL/min) and 2160 ng·h/mL (95% CI, 929-3390 ng·h/mL), respectively, in all patients with T1DM and T2DM. Observed FPG in patients with T1DM was reproduced well by the simulation from the previously established FPG model. IMPLICATIONS: The PK/PD properties for ipragliflozin were comparable between patients with T1DM and T2DM, suggesting no substantial difference in PK/PD relationships in both patient populations. The dose regimen used for patients with T2DM was also recommended for a Phase III study in Japanese patients with T1DM. ClinicalTrials.gov identifiers: NCT01023945 and NCT02529449.

SGLT2 Inhibitor and GLP-1 Receptor Agonist Combination Therapy Substantially Improved the Renal Function in a Patient with Type 2 Diabetes: Implications for Additive Renoprotective Effects of the Two Drug Classes.

A 72-year-old man had type 2 diabetes (T2D) that had been diagnosed at 54 years old. Macroalbuminuria was first detected at age 64. While his HbA1c had been kept below 7%, his estimated glomerular filtration rate (eGFR) was declining rapidly. At 70 years old, his eGFR dropped below 50 mL/min/1.73 m2. A renal biopsy revealed diabetic nephropathy. Sodium glucose transporter 2 inhibitors (SGLT2i)/glucagon-like peptide-1 receptor agonists (GLP-1RA) combination therapy substantially improved his eGFR and urinary albumin level, and the renoprotective effect persisted for the two-year study period. These findings suggest that SGLT2i and GLP-1RA can additively improve the renal function in patients with T2D.

Targeting oxidative stress, proinflammatory cytokines, apoptosis and toll like receptor 4 by empagliflozin to ameliorate bleomycin-induced lung fibrosis.

Lung fibrosis is one of the serious complications of bleomycin use in cancer therapy. The aim of this study was to investigate the effect of pre-treatment versus post-treatment with empagliflozin on pulmonary fibrosis induced by bleomycin. One hundred male C57BL/6 mice were divided into 5 equal groups as follows: control group; bleomycin group; bleomycin + carboxymethyl cellulose group; bleomycin group pretreated with empagliflozin and a group treated with empagliflozin after 15 days from starting bleomycin injection. The survival rate, lung weight/body weight ratio, lung tissue hydroxyproline, malondialdehyde, glutathione reductase, superoxide dismutase, nuclear factor (Erythroid-derived 2)-like 2 (Nrf2), heme oxygenase-1 (HO-1) and toll-like receptor 4 (TLR4) were assessed. Also, bronchoalveolar lavage fluid (BALF) was analyzed for total and differential leucocytic count, lactate dehydrogenase, interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta 1 (TGF-ß1). The pulmonary tissues were subjected to histopathological, immunohistochemical and electron microscopic study. Empagliflozin induced significant decrease in lung weight/body weight ratio, BALF lactate dehydrogenase, total leucocytic count, IL-6, TNF-α, TLR4 and TGF-ß1 associated with significant decrease in lung tissue oxidative stress and hydroxyproline and significant increase in the survival rate and tissue Nrf2/HO-1 content compared to bleomycin group. This was accompanied with significant improvement of the histopathological, immunohistochemical and electron microscopic picture compared to bleomycin group. These effects were significant in mice pretreated with empagliflozin compared to the group that received empagliflozin 15 days after starting bleomycin injection. In conclusion, empagliflozin may be used prophylactically to prevent pulmonary fibrosis induced by bleomycin.

Effects of exenatide and open-label SGLT2 inhibitor treatment, given in parallel or sequentially, on mortality and cardiovascular and renal outcomes in type 2 diabetes: insights from the EXSCEL trial.

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1 RA) improve cardiovascular and renal outcomes in patients with type 2 diabetes through distinct mechanisms. However, evidence on clinical outcomes in patients treated with both GLP-1 RA and SGLT2i is lacking. We aim to provide insight into the effects of open-label SGLT2i use in parallel with or shortly after once-weekly GLP-1 RA exenatide (EQW) on cardiorenal outcomes. METHODS: In the EXSCEL cardiovascular outcomes trial EQW arm, SGLT2i drop-in occurred in 8.7% of participants. These EQW+SGLT2i users were propensity-matched to: (1) placebo-arm participants not taking SGLT2i (n = 572 per group); and to (2) EQW-arm participants not taking SGLT2i (n = 575), based on their last measured characteristics before SGLT2i initiation, and equivalent study visit in comparator groups. Time-to-first major adverse cardiovascular event (MACE) and all-cause mortality (ACM) were compared using Cox regression analyses. eGFR slopes were quantified using mixed model repeated measurement analyses. RESULTS: In adjusted analyses, the risk for MACE with combination EQW+SGLT2i use was numerically lower compared with both placebo (adjusted hazard ratio 0.68, 95% CI 0.39-1.17) and EQW alone (0.85, 0.48-1.49). Risk of ACM was nominally significantly reduced compared with placebo (0.38, 0.16-0.90) and compared with EQW (0.41, 0.17-0.95). Combination EQW+SGLT2i use also nominally significantly improved estimated eGFR slope compared with placebo (+ 1.94, 95% CI 0.94-2.94 mL/min/1.73 m2/year) and EQW alone (+ 2.38, 1.40-3.35 mL/min/1.73 m2/year). CONCLUSIONS: This post hoc analysis supports the hypothesis that combinatorial EQW and SGLT2i therapy may provide benefit on cardiovascular outcomes and mortality.

Efficacy and safety of sodium-glucose cotransporter-2 inhibitors in type 2 diabetes mellitus with inadequate glycemic control on metformin: a meta-analysis

ABSTRACT Objectives To provide a meta-analysis of the clinical efficacy and safety of sodium glucose co-transporter 2 inhibitors (SGLT2-i), as a combination treatment with metformin in type 2 diabetes mellitus (T2DM) patients with inadequate glycemic control with metformin alone. Materials and methods We have searched randomized controlled trials (RCTs) in the database: MEDLINE, Embase and Cochrane Collaborative database. We used mean differences (MD) to assess the efficacy of glycemic and other clinical parameters, and risk ratios (RR) to evaluate the adverse events for safety endpoints. The heterogeneity was evaluated by I2. Results Finally 9 studies were included. SGLT2-i plus metformin had higher reduction level in HbA1C [MD = -0.50, 95% CI (-0.62, -0.38), p < 0.00001], FPG [MD = -1.12, 95%CI (-1.38, -0.87), p < 0.00001], body weight [MD = -1.72, 95% CI (-2.05, -1.39), p < 0.00001], SBP [MD = -4.44, 95% CI (-5.45, -3.43), p < 0.00001] and DBP [MD = -1.74, 95% CI (-2.40, -1.07), p < 0.00001] compared with metformin monotherapy. However, SGLT2-i plus metformin group had higher risk of genital infection [RR = 3.98, 95% CI (2.38, 6.67), p < 0.00001]. No significant difference was found in the risk of hypoglycemia, urinary tract infection or volume related adverse events. Conclusions Although the risk of genital infection may increase, SGLT2-i plus metformin may provide an attractive treatment option to those T2DM patients who are unable to achieve glycemic control with metformin alone, based on its effects on glycemic control, reducing body weight and lowering blood pressure.

Switching to iGlarLixi Versus Continuing Daily or Weekly GLP-1 RA in Type 2 Diabetes Inadequately Controlled by GLP-1 RA and Oral Antihyperglycemic Therapy: The LixiLan-G Randomized Clinical Trial.

OBJECTIVE: Fixed-ratio combinations of basal insulin plus glucagon-like peptide 1 receptor agonist (GLP-1 RA) allow concomitant administration of two proven complementary injectable therapies for type 2 diabetes. This study investigated switching to a titratable fixed-ratio combination of insulin glargine plus lixisenatide (iGlarLixi) in patients with type 2 diabetes receiving daily or weekly GLP-1 RA therapy. RESEARCH DESIGN AND METHODS: LixiLan-G, a randomized, open-label, 26-week trial, compared switching to iGlarLixi versus continuing prior GLP-1 RA in patients with type 2 diabetes and HbA1c 7-9% (53-75 mmol/mol) taking maximum tolerated doses of a GLP-1 RA daily (60% on liraglutide once daily or exenatide twice daily) or weekly (40% on dulaglutide, exenatide extended release, or albiglutide) with metformin with or without pioglitazone and with or without sodium-glucose cotransporter 2 inhibitors. Adherence to randomized treatment was closely monitored throughout the study. RESULTS: iGlarLixi (n = 257) reduced HbA1c more than continued GLP-1 RA therapy (n = 257) from a baseline 7.8% (62 mmol/mol) in both to 6.7% (50 mmol/mol) and 7.4% (57 mmol/mol), respectively, at 26 weeks (least squares mean difference -0.6%; P < 0.0001). More iGlarLixi patients achieved HbA1c <7% (53 mmol/mol) (62% vs. 26%; P < 0.0001) and the composite of HbA1c <7% without documented symptomatic hypoglycemia (<54 mg/dL). Nausea and vomiting rates as well as numbers of documented symptomatic hypoglycemia events per patient-year were generally low but greater with iGlarLixi versus continued GLP-1 RA therapy. CONCLUSIONS: Switching to iGlarLixi improves glucose control for patients with type 2 diabetes insufficiently controlled on a maximum tolerated dose of a GLP-1 RA plus oral antihyperglycemic agents.

Comparative efficacy of once-weekly semaglutide versus SGLT-2 inhibitors in patients inadequately controlled with one to two oral antidiabetic drugs: a systematic literature review and network meta-analysis.

OBJECTIVE: To determine the comparative efficacy of once-weekly semaglutide relative to sodium-glucose cotransporter 2 inhibitors (SGLT-2is) licensed in Europe and North America among patients with type 2 diabetes (T2D) inadequately controlled with 1-2 oral antidiabetics (OADs), using a network meta-analysis (NMA). Design systematic review and network meta-analysis. Data Sources EMBASE, MEDLINE and CENTRAL were searched from January 1994 to August 2017. METHODS: Randomised controlled trials with ≥20 weeks of treatment evaluating once-weekly semaglutide or SGLT-2is. Primary outcomes included change from baseline in: HbA1c, weight, systolic blood pressure, postprandial blood glucose and fasting plasma glucose. Fixed-effect and random-effect Bayesian NMA were used to indirectly compare treatment effects at 26 (±4) weeks. Metaregression and sensitivity analyses were conducted. Model selection was performed using the deviance information criterion and consistency was assessed by comparing indirect (edge-splitting) to direct evidence. RESULTS: Forty-eight publications representing 21 trials were included. The mean differences (MD) in change from baseline in HbA1c of once-weekly semaglutide 1.0 mg versus SGLT-2is ranged from -0.56% for canagliflozin 300 mg (95% credible interval (CrI): -0.76 to -0.33%), to -0.95% for dapagliflozin 5 mg (95% CrI: -1.20 to -0.69%). The MD in change from baseline in weight of once-weekly semaglutide 1.0 mg versus SGLT-2is ranged from -1.35 kg for canagliflozin 300 mg to -2.48 kg for dapagliflozin 5 mg, while change from baseline in fasting plasma glucose ranged from -0.41 mmol/L for canagliflozin 300 mg to -1.37 mmol/L for dapagliflozin 5 mg. Once-weekly semaglutide was not statistically differentiable than all SGLT-2is in reducing systolic blood pressure. NMA was not feasible for postprandial blood glucose and safety outcomes. CONCLUSION: Once-weekly semaglutide demonstrated statistically significant and clinically meaningful reductions in HbA1c and body weight in T2D patients inadequately controlled with 1-2 OADs compared to all SGLT-2is licensed in Europe and North America.
