Sodium glucose cotransporter 2 inhibitors with cardiac arrhythmias in patients with type 2 diabetes mellitus: a systematic review and meta-analysis of randomized placebo-controlled trials. Clin Res Cardiol 2024; 113:910-923. [PMID: 38353684 DOI: 10.1007/s00392-024-02386-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 01/25/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is associated with an increased risk of cardiac arrhythmias, which increases serious morbidity and mortality. Novel hypoglycemic drug sodium glucose cotransporter 2 (SGLT2) inhibitor has shown sufficient cardiovascular benefits in cardiovascular outcome trials. OBJECTIVE This systematic review and meta-analysis aimed to investigate the relationship between SGLT2 inhibitors and cardiac arrhythmias in patients with T2DM. METHODS We searched on PubMed and ClinicalTrials.gov for at least 24 weeks of randomized double-blind placebo-controlled trials involving T2DM subjects assigned to SGLT2 inhibitors or placebo as of May 5, 2023. Risk ratio (RR) with 95% confidence interval (CI) were used for binary variables. Primary outcomes included atrial arrhythmias, ventricular arrhythmias, bradyarrhythmias, cardiac arrest, and atrial fibrillation/atrial flutter. Secondary outcomes comprised atrial fibrillation, atrial flutter, ventricular fibrillation, ventricular tachycardia, atrioventricular block, and sinus node dysfunction. RESULTS We included 32 trials covering 60,594 T2DM patients (SGLT2 inhibitor 35,432; placebo 25,162; mean age 53.9 to 68.5 years). SGLT2 inhibitors significantly reduced the risk of atrial arrhythmias (RR 0.86; 95%CI 0.74-0.99; P = 0.04) or atrial fibrillation/flutter (RR 0.85; 95%CI 0.74-0.99; P = 0.03) compared to placebo; in subgroup analysis, SGLT2 inhibitors achieved a consistent effect with overall results in T2DM with high cardiovascular risk or follow-up > 1 year populations. There was no substantial evidence to suggest that SGLT2 inhibitors reduced the risk of ventricular arrhythmias (RR 0.94; 95%CI 0.71-1.26; P = 0.69) and cardiac arrest (RR 0.88; 95%CI 0.66-1.18; P = 0.39). A neutral effect of SGLT2 inhibitors on bradyarrhythmias was observed (RR 1.02; 95%CI 0.79-1.33; P = 0.85). SGLT2 inhibitors had no significant impact on all secondary outcomes compared to placebo, while it had borderline effect for atrial fibrillation. CONCLUSION SGLT2 inhibitors were associated with a reduced risk of atrial arrhythmias in patients with T2DM. Our results support the use of SGLT2 inhibitors in T2DM with high cardiovascular risk populations. We also recommend the long-term use of SGLT2 inhibitors to achieve further benefits.

The role of SGLT2i in attenuating residual cardiovascular risk through blood pressure-lowering: mechanistic insights and perspectives. FRONTIERS IN CLINICAL DIABETES AND HEALTHCARE 2023; 4:1243530. [PMID: 37822556 PMCID: PMC10562622 DOI: 10.3389/fcdhc.2023.1243530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 09/11/2023] [Indexed: 10/13/2023]
Abstract
Sodium glucose cotransporter 2 inhibitors (SGLT2) have been increasingly pursued as a promising target for addressing residual cardiovascular risk. Prior trials demonstrated that SGLT2i not only promotes glucose-lowering, but also improves endothelial dysfunction, adiposity, fluid overload, and insulin sensitivity thus contributing to hemodynamic changes implicated in its cardiorenal benefits. The mechanisms in the effect of SGLT2i on blood pressure and their potential role in preventing cardiovascular events are hereby revised.

Abstract
OBJECTIVE Multiple trials on sodium-glucose cotransporter (SGLT) inhibitors have been performed recently demonstrating blood pressure (BP) reduction benefits in both diabetic and nondiabetic patients. Hence, we conducted a systematic review and meta-analysis to determine the effect of different SGLT inhibitors on BP in both patients with and without diabetes mellitus. METHODS Four electronic databases (PubMed, Embase, Cochrane, and SCOPUS) were searched on 4 November 2021 for articles published from 1 January 2000 up to 21 November 2021, for studies evaluating the BP effects of SGLT inhibitors. Pair-wise meta-analysis and random effects metaregression models were utilized. RESULTS In total, 111 studies examining SBP (108 studies, 104 304 patients) and/or DBP (82 studies, 74 719 patients) were included. In patients with diabetes, the random effects model demonstrated SGLT inhibitor produced a mean reduction in SBPs of -3.46 mmHg (95% confidence interval: -3.83, -3.09) compared with placebo. There were no statistically significant changes in BP among patients without diabetes. Drug response relationship was not observed in SGLT inhibitors and BP, except for Canagliflozin and DBP. CONCLUSION Sodium-glucose cotransporter 2 inhibitors and combined sodium-glucose cotransporter 1/2 inhibitors produced small reductions in BP in patients with diabetes.

Abstract
Recent insights into the pathophysiologic underlying mechanisms of obesity have led to the discovery of several promising drug targets and novel therapeutic strategies to address the global obesity epidemic and its comorbidities. Current pharmacologic options for obesity management are largely limited in number and of modest efficacy/safety profile. Therefore, the need for safe and more efficacious new agents is urgent. Drugs that are currently under investigation modulate targets across a broad range of systems and tissues, including the central nervous system, gastrointestinal hormones, adipose tissue, kidney, liver, and skeletal muscle. Beyond pharmacotherapeutics, other potential antiobesity strategies are being explored, including novel drug delivery systems, vaccines, modulation of the gut microbiome, and gene therapy. The present review summarizes the pathophysiology of energy homeostasis and highlights pathways being explored in the effort to develop novel antiobesity medications and interventions but does not cover devices and bariatric methods. Emerging pharmacologic agents and alternative approaches targeting these pathways and relevant research in both animals and humans are presented in detail. Special emphasis is given to treatment options at the end of the development pipeline and closer to the clinic (ie, compounds that have a higher chance to be added to our therapeutic armamentarium in the near future). Ultimately, advancements in our understanding of the pathophysiology and interindividual variation of obesity may lead to multimodal and personalized approaches to obesity treatment that will result in safe, effective, and sustainable weight loss until the root causes of the problem are identified and addressed.

Abstract
Disease burden in people with diabetes is mainly driven by long-term complications such as cardiovascular disease, heart failure and chronic kidney disease. This is a consequence of the interconnection between the cardiovascular, renal and metabolic systems, through a continuous chain of events referred to as 'the cardiorenal metabolic continuum'. Increasing evidence suggests that sodium-glucose cotransporter 2 inhibitors (SGLT2is) have beneficial effects across all stages of the cardiorenal metabolic continuum, reducing morbidity and mortality in a wide range of individuals, from those with diabetes and multiple risk factors to those with established heart failure and chronic kidney disease, regardless of the presence of diabetes. Despite this robust evidence base, the complexity of label indications and misconceptions concerning potential side effects have resulted in a lack of clear understanding in primary care regarding the implementation of SGLT2is in clinical practice. With this in mind, we provide an overview of the clinical and economic benefits of SGLT2is across the cardiorenal metabolic continuum together with practical considerations in order to help address some of these concerns and clearly define the role of SGLT2is in primary care as a holistic outcomes-driven treatment with the potential to reduce disease burden across the cardiorenal metabolic spectrum.

Effects of Sodium/Glucose Cotransporter 2 (SGLT2) Inhibitors and Combined SGLT1/2 Inhibitors on Cardiovascular, Metabolic, Renal, and Safety Outcomes in Patients with Diabetes: A Network Meta-Analysis of 111 Randomized Controlled Trials. Am J Cardiovasc Drugs 2022; 22:299-323.

Abstract
INTRODUCTION Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a class of anti-hyperglycemic drugs that has been steadily increasing in popularity due to its cardiovascular and renal benefits. Dual SGLT1/SGLT2 (SGLT1/2) inhibitors have potentially augmented anti-hyperglycemic action due to additional SGLT1 inhibition. This network meta-analysis aimed to compare the treatment effect across various outcomes between pure SGLT2 inhibitors and combined SGLT1/2 inhibitors in patients with diabetes. METHODOLOGY Four electronic databases (PubMed, Embase, Cochrane, and Scopus) were searched for randomized controlled trials published from inception to 15th January 2022. Frequentist network meta-analysis was conducted to summarize the treatment effects reported in individual trials, stratified by type 1 (T1DM) and type 2 diabetes mellitus (T2DM). This meta-analysis was registered on PROSPERO (CRD42020222031). RESULTS Our meta-analysis included 111 articles, comprising a combined cohort of 103,922 patients. SGLT2 inhibitors (dapagliflozin, empagliflozin, canagliflozin, ipragliflozin, ertugliflozin, and luseogliflozin) and SGLT1/2 inhibitors (licogliflozin and sotagliflozin) were compared. Frequentist network meta-analysis demonstrated that in T2DM patients, SGLT1/2 inhibitors led to a decreased hazard rate of myocardial infarction (hazard ratio [HR] 0.74, 95% confidence interval [CI] 0.56-0.98) and stroke (HR 0.65, 95% CI 0.47-0.92) compared with SGLT2 inhibitors. SGLT2 inhibitors achieved a greater hemoglobin A1c (HbA1c) reduction than SGLT1/2 inhibitors (0.16%, 95% CI 0.06-0.26). In patients with T2DM, the risk of diarrhea (risk ratio [RR] 1.42, 95% CI 1.07-1.88) and severe hypoglycemia (RR 5.89, 95% CI 1.41-24.57) were found to be higher with SGLT1/2 inhibitor use compared with SGLT2 inhibitor use. No differences were observed for cardiovascular, metabolic, and safety outcomes between SGLT1/2 inhibitors and SGLT2 inhibitors in patients with T1DM. CONCLUSIONS In patients with T2DM, compared with pure SGLT2 inhibitors, combined SGLT1/2 inhibitors demonstrated a lower risk of myocardial infarction and of stroke, but were associated with a higher risk of diarrhea and severe hypoglycemia.

Abstract
BACKGROUND A network meta-analysis of randomized controlled trials (RCTs) was conducted to explore the cardiovascular outcomes of all the kind and dosages of sodium-glucose cotransport-2 (SGLT2) inhibitors in type 2 diabetes mellitus (T2DM) patients. METHOD AND RESULT The Cochrane Library, PubMed, and Embase databases were systematically searched for studies to compare the therapeutic effects of different SGLT2 inhibitors in T2DM patients. The effect measurements estimate chosen were odds ratios (ORs) and their corresponding 95% confidence interval (CI). Forty-seven RCTs involving a total of 70574 participants were eligible for direct and indirect comparisons. In direct comparison, treatment with dapagliflozin 5mg showed significantly lower risk of all-cause mortality compared with treatment with dapagliflozin 2.5mg (OR 0.09, 95% CI 0.01-0.70). According to NMA, interestingly, empagliflozin 10mg/25mg, and canagliflozin 100mg was associated with significantly lower risks of all-cause mortality compared with placebo (OR of 0.70, 95% CI 0.58-0.85; 0.69, 95% CI 0.57-0.84; and 0.83, 95% CI 0.73-0.95, respectively). Compared with placebo, dapagliflozin 10mg, empagliflozin 10mg and 25mg displayed the lower risks for cardiovascular events (OR 0.78, 95% CI 0.44-1.00; OR 0.47, 95% CI 0.22-0.93; and 0.43, 95% CI 0.24-0.74, respectively) by direct comparison. Moreover, canagliflozin 100/300mg showed significantly higher risks of cardiovascular events compared with empagliflozin 10mg (OR of 4.83, 95% CI 1.14-20.46 and 5.31, 95% CI 1.26-22.34, respectively) and empagliflozin 25mg (4.23, 95% CI 1.13-15.83 and 4.65, 95% CI 1.25-17.27, respectively) according to NMA. There were non-significant differences among all interventions in volume depletion in traditional pairwise meta-analysis. While in NMA, canagliflozin 100/300mg were associated with significantly increased risks of volume depletion compared with placebo (OR of 1.47, 95% CI 1.08-1.99 and 2.19, 95% CI 1.66-2.90, respectively). CONCLUSION In the limitations of the NMA, this study showed that empagliflozin might be better than other SGLT2 inhibitors with low risks of all-cause mortality and cardiovascular events in patients with T2DM suggesting the need for ad hoc RCTs.

Abstract
OBJECTIVE Multiple trials have demonstrated the metabolic effects of sodium/glucose cotransporter 2 (SGLT2) inhibitors in patients regardless of diabetes status, and recent trials have been conducted on the combined sodium/glucose cotransporter 1 and sodium/glucose cotransporter 2 (SGLT1/SGLT2) inhibitors. Therefore, a meta-analysis was conducted to investigate the weight reduction effects and dose-response relationship of SGLT inhibitors and to assess the relative efficacy of SGLT1/SGLT2 inhibitors. METHODS Four electronic databases (PubMed, Embase, Cochrane, and Scopus) were searched on November 21, 2020, for articles published from January 1, 2000, up to November 21, 2020. RESULTS In total, 116 randomized-controlled trials were included, with a combined cohort of 98,497 patients. Overall, patients had a mean weight reduction of -1.79 kg (95% CI: -1.93 to -1.66, p < 0.001) compared with placebo. This effect was observed across diabetes status, duration of follow-up, various comorbidities, and all SGLT drug types. Mean BMI changes were -0.71 kg/m2 (95% CI: -0.94 to -0.47, p < 0.001) compared with placebo. Canagliflozin, empagliflozin, sotagliflozin, and licogliflozin showed a dose-response relationship for mean weight change. Compared with SGLT2 inhibitors, SGLT1/SGLT2 inhibitors had a significantly larger reduction in weight. CONCLUSIONS SGLT inhibitors demonstrated weight reduction benefits in this meta-analysis. Further studies are needed to clarify their role in weight management.

Abstract
Diabetes mellitus (DM) represents a major public health problem, with yearly increasing prevalence. DM is considered a progressive vascular disease that develops macro and microvascular complications, with a great impact on the quality of life of diabetic patients. Over time, DM has become one of the most studied diseases; indeed, finding new pharmacological ways to control it is the main purpose of the research involved in this issue. Sodium–glucose cotransporter 2 inhibitors (SGLT-2i) are a modern drug class of glucose-lowering agents, whose use in DM patients has increased in the past few years. Besides the positive outcomes regarding glycemic control and cardiovascular protection in DM patients, SGLT-2i have also been associated with metabolic benefits, blood pressure reduction, and improved kidney function. The recent perception and understanding of SGLT-2i pathophysiological pathways place this class of drugs towards a particularized patient-centered approach, moving away from the well-known glycemic control strategy. SGLT-2i have been shown not only to reduce death from cardiovascular causes, but also to reduce the risk of stroke and heart failure hospitalization. This article aims to review and highlight the existing literature on the effects of SGLT-2i, emphasizing their role as oral antihyperglycemic agents in type 2 DM, with important cardiovascular and metabolic benefits.

Abstract
Background This study aimed to assess the effectiveness of sodium‐glucose cotransporter 2 inhibitors in reducing the incidence of mortality and cardiovascular outcomes in adults with type 2 diabetes. Methods and Results We conducted a Bayesian meta‐analysis of randomized controlled trials comparing sodium‐glucose cotransporter 2 inhibitors with placebo. We used meta‐regression to examine the association between treatment effects and control group event rates as measures of cardiovascular baseline risk. Fifty‐three randomized controlled trials were included in our synthesis. Empagliflozin, canagliflozin, and dapagliflozin reduced the incidence of all‐cause mortality (empagliflozin: rate ratio [RR], 0.79; 95% credibility interval [CrI], 0.63–0.97; canagliflozin: RR, 0.86; 95% CrI, 0.69–1.05; dapagliflozin: RR, 0.86; 95% CrI, 0.72–1.01) and cardiovascular mortality (empagliflozin: RR, 0.78; 95% CrI, 0.61–1.00; canagliflozin: RR, 0.83; 95% CrI, 0.63–1.05; dapagliflozin: RR, 0.88; 95% CrI, 0.71–1.08), with a 90.1% to 98.7% probability for the true RR to be <1.00 for both outcomes. There was little evidence for ertugliflozin and sotagliflozin versus placebo for reducing all‐cause and cardiovascular mortality. There was no association between treatment effects for all‐cause and cardiovascular mortality and the control group event rates. There was evidence for a reduction in the incidence of heart failure for empagliflozin, canagliflozin, dapagliflozin, and ertugliflozin versus placebo (probability RR <1.00 of ≥99.3%) and weaker, albeit positive, evidence for acute myocardial infarction for the first 3 agents (probability RR <1.00 of 89.0%–95.2%). There was little evidence of any agent except canagliflozin for reducing the incidence of stroke. Conclusions Empagliflozin, canagliflozin, and dapagliflozin reduced the incidence of all‐cause and cardiovascular mortality versus placebo. Treatment effects of sodium‐glucose cotransporter 2 inhibitors versus placebo do not vary by baseline risk.

Effects of Dapagliflozin Adjunct to Insulin on Glycemic Variations in Patients with Newly Diagnosed Type 2 Diabetes: A Randomized, Controlled, Open-Labeled Trial. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6618257. [PMID: 34497852 PMCID: PMC8419509 DOI: 10.1155/2021/6618257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 08/10/2021] [Indexed: 01/10/2023]
Abstract
Background This study is aimed at investigating whether dapagliflozin adjunct to insulin therapy further improves glycemic control compared to insulin therapy alone in patients with newly diagnosed type 2 diabetes (T2D). Methods This single-centre, randomized, controlled, open-labeled trial recruited newly diagnosed T2D patients. Subjects were randomized 1 : 1 to the dapagliflozin add-on to continuous subcutaneous insulin infusion (CSII) group (DAPA) or the CSII therapy group for 5 weeks. Standard meal tests were performed 3 times at days -3, 7, and 35 for glucose, C-peptide, and insulin level determination. Two-time continuous glucose monitoring (CGM) was performed at baseline and at the end of the study. The primary endpoint was the difference in the mean amplitude of glycemic excursions (MAGEs) between the groups. Results A total of 66 subjects completed the study, with 34 and 32 patients in the DAPA and CSII groups, respectively. Patients in the DAPA group exhibited significant decreases in MAGE levels at the endpoint. We also observed that patients in the DAPA group had a lower homoeostasis model assessment insulin resistance (HOMA-IR) and a higher homoeostasis model assessment B (HOMA-B) value at 1 week and 5 weeks compared to those with insulin therapy, respectively. In addition, our data showed that patients in the DAPA group showed a significantly lower insulin dose (0.07 U/kg) and weighed less than those in the CSII group. Conclusion Our data indicate that dapagliflozin adjunct to insulin is a safe and effective therapy for improving glycemic variations, insulin sensitivity, and weight loss in newly diagnosed T2D patients.

Abstract
INTRODUCTION Sodium-glucose cotransporter (SGLT) 2 inhibitors reduce glucose reabsorption in the kidney, increase glucosuria, and improve glycemia. Besides glycemic efficacy, the class also lowers risk of cardiovascular and renal disease. AREAS COVERED The authors describe late phase trials of empagliflozin, canagliflozin, dapagliflozin, and ertugliflozin. Safety and efficacy endpoints in monotherapy, combination therapy, cardiovascular, and renal outcomes trials have been identified and presented. EXPERT OPINION SGLT2 inhibitors appear to be safe and effective agents that improve glycemia when used alone or in combination with any other approved antihyperglycemic medications. Other beneficial effects include reductions in body weight and blood pressure, improvements in renal outcomes, all-cause mortality, cardiovascular mortality, and worsening heart failure.

Abstract
Background: Currently, the association between sodium-glucose cotransporter 2 inhibitor (SGLT-2i) and malignancy risk has yet to be fully elucidated. This meta-analysis aimed to determine the relationship between SGLT-2i and malignancy risk in type 2 diabetes (T2D) patients. Methods: We searched PubMed, ScienceDirect, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science to identify randomized controlled trials (RCTs) published up to August 2020 related to T2D patients treated with SGLT-2i vs. placebo or other hypoglycemic agents. The meta-analysis's primary outcome was malignancies' incidence, and the results were evaluated using risk ratio (RR) and 95% confidence interval (CI). Results: We reviewed 76 articles (77 RCTs), comprising 45,162 and 43,811 patients in SGLT-2i and control groups, respectively. Compared with the control group, SGLT-2i had no significant association with augmented overall malignancy risk in T2D patients (RR = 1.05, 95% CI = 0.97–1.14, P = 0.20), but ertugliflozin may upsurge the risk (RR = 1.80, 95% CI = 1.02–3.17, P = 0.04). Compared with active hypoglycemic agents, dapagliflozin may increase (RR = 2.71, 95% CI = 1.46–6.43, P = 0.02) and empagliflozin may decrease (RR = 0.67, 95% CI = 0.45–0.98, P = 0.04) the malignancy risk. Compared with placebo, empagliflozin may exhibit risk increase (RR = 1.25, 95% CI = 1.05–1.49, P = 0.01), primarily in digestive system (RR = 1.48, 95% CI = 0.99–2.21, P = 0.05). Conclusions: Our results proposed that in diverse comparisons, ertugliflozin and dapagliflozin seemed to increase the malignancy risk in T2D patients. Empagliflozin may cause malignancy risk reduction compared with active hypoglycemic agents but increase overall risk primarily in the digestive system compared with placebo. In short, the relationship between SGLT-2i and malignancy in T2D patients remains unclear.

[PMID: 33659605 PMCID: PMC7892922 DOI: 10.1016/j.ijcha.2021.100725] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 12/28/2020] [Accepted: 01/19/2021] [Indexed: 02/06/2023]
Abstract
OBJECTIVE Clinical trials suggest that SGLT2 inhibitors reduce the risk of cardiovascular mortality in patients with type 2 diabetes, however the mechanism is unclear. Our objective was to test the hypothesis that blood pressure reduction is one potential mechanism underlying the observed improvements in cardiovascular outcomes with SGLT2 inhibitors. METHODS We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (inception-June 2019) for randomized controlled trials that reported the effect of SGLT2 inhibitors compared with placebo on cardiovascular outcomes in adults with type 2 diabetes. Two reviewers independently extracted data and assessed study quality. Random effects meta-analyses, stratified meta-analyses and meta-regressions were conducted to evaluate the association between blood pressure reduction in SGLT2 inhibitor treated patients and cardiovascular outcomes. RESULTS Of 11,232 articles identified, 40 articles (n = 54,279 participants) were included. The relative risk of cardiovascular mortality was reduced by 18% with the use of SGLT2 inhibitors compared with placebo (RR 0.82; 95%CI 0.74, 0.91, I2 = 0.0%). Meta-regression analysis revealed no detectable difference in cardiovascular mortality (RR 0.93; 95%CI 0.88, 1.13, p = 0.483), 3-point major adverse cardiovascular events (p = 0.839) or congestive heart failure hospitalizations (p = 0.844) with change in mean systolic blood pressure. CONCLUSIONS Cardiovascular events are reduced in participants with type 2 diabetes treated with SGLT2 inhibitors compared with placebo. There was no significant relationship between the risk of developing adverse cardiovascular events and blood pressure reduction with SGLT2 inhibitors. There is insufficient evidence to suggest that blood pressure reduction is a significant contributor to the cardiovascular benefits observed.

Adding Sodium-Glucose Co-Transporter 2 Inhibitors to Sulfonylureas and Risk of Hypoglycemia: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Front Endocrinol (Lausanne) 2021; 12:713192. [PMID: 34744998 PMCID: PMC8568344 DOI: 10.3389/fendo.2021.713192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Accepted: 10/04/2021] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Hypoglycemia is an important event that could be related to increased mortality in patients with diabetes. The risk of hypoglycemia is not clearly illustrated to increase when Sodiumglucose co-transporter 2 (SGLT-2) inhibitors are used concomitantly with sulfonylureas. The present study will assess the risk of hypoglycemia associated with the concomitant use of SGLT-2 inhibitors and sulfonylureas compared with placebo and sulfonylureas. METHOD We searched Medline, EMBASE, Cochrane Central Register of Controlled Trials, and Clinicaltrial.gov and identified the randomized trials comparing SGLT-2 inhibitors with placebo for type 2 diabetes treated with sulfonylureas. The risk of bias in each trial was assessed using the Cochrane tool. The risk ratio of hypoglycemia was measured using the Mantel Haenszel method. We also performed subgroup analysis to examine the dosage effects. The number needed to harm (NNH) was measured according to the duration of intervention. RESULTS A total of 12 studies, including 3761 participants, were enrolled in our systematic review and meta-analysis. The risk ratio of hypoglycemia was 1.67 (95% CI 1.42 to 1.97). The NNH was 13 (95% CI 9 to 21) for a treatment duration of 24 weeks or less, 11 (8 to 18) for 25 to 48 weeks, and 7 (5 to 10) for more than 48 weeks. Subgroup analysis showed that no difference was found between higher and lower doses of SGLT-2 inhibitors. The risk ratio related to lower dose SGLT-2 inhibitors was 1.56 (95% CI 1.30 to 1.88), and the risk ratio related to higher dose SGLT-2 inhibitors was 1.70 (95% CI 1.42 to 2.04). CONCLUSIONS The risk of hypoglycemia was significantly increased in subjects treated with SGLT-2 inhibitors compared with placebo. Addition of SGLT-2 inhibitors to sulfonylureas would lead to one more case of hypoglycemia in every 13 patients with a treatment duration less than 24 weeks. This suggests that a decrease in sulfonylureas dose may be an important recommendation when adding SGLT-2 inhibitors to sulfonylureas.

Abstract
AIMS The long-term impact of sodium glucose cotransporter 2 (SGLT2) inhibitors on renal functions remains undefined. This study was undertaken to investigate the renal outcomes associated with SGLT2 inhibitors in patients with type 2 diabetes (T2DM) in the long term. METHODS A systematic literature search of PubMed and ClinicalTrials.gov was conducted. Randomized controlled trials which reported renal outcomes at the study endpoint in patients with T2DM receiving treatments of SGLT2 inhibitors were included. Renal adverse events were determined using prespecified lists from the Medical Dictionary for Regulatory Activities or laboratory values. Odds ratio with 95% confidence interval (CI) was used for assessment of dichotomous data. The mean difference or standardized mean difference with 95% CI was used for assessment of continuous data. Random effects models were adopted to measure the pooled outcomes. RESULTS Thirty-nine studies involving 35 trials were identified. Compared with placebo or other anti-diabetic medications, SGLT2 inhibitors were associated with significant lower incidence of composite renal outcome and acute renal failure or injury in patients with T2DM. The risk of progression of albuminuria also appeared to be decreased. No significant changes of estimated glomerular filtration rate levels or urine albumin-creatinine ratios were found in patients receiving SGLT2 inhibitors. CONCLUSIONS Overall renal safety and beneficial effects are indicated for SGLT2 inhibitors. Further confirmative data from large trials and real-world studies are needed.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT2i) improve cardiovascular outcomes in patients with type 2 diabetes mellitus (T2D). The comparative efficacy of individual SGLT2i remains unclear. We searched PubMed, www.clinicaltrials.gov and the Cochrane Central Register of Controlled Trials for randomised controlled trials exploring the use of canagliflozin, dapagliflozin, empagliflozin or ertugliflozin in patients with T2D. Comparators included placebo or any other active treatment. The primary endpoint was all-cause mortality. Secondary endpoints were cardiovascular mortality and worsening heart failure (HF). Evidence was synthesised using network meta-analysis (NMA). Sixty-four trials reporting on 74,874 patients were included. The overall quality of evidence was high. When compared with placebo, empagliflozin and canagliflozin improved all three endpoints, whereas dapagliflozin improved worsening HF. When compared with other SGLT2i, empagliflozin was superior for all-cause and cardiovascular mortality reduction. Empagliflozin, canagliflozin and dapagliflozin had similar effects on improving worsening HF. Ertugliflozin had no effect on any of the three endpoints investigated. Sensitivity analyses including extension periods of trials or excluding studies with a treatment duration of < 52 weeks confirmed the main results. Similar results were obtained when restricting mortality analyses to patients included in cardiovascular outcome trials (n = 38,719). Empagliflozin and canagliflozin improved survival with empagliflozin being superior to the other SGLT2i. Empagliflozin, canagliflozin and dapagliflozin had similar effects on improving worsening HF. Prospective head-to-head comparisons would be needed to confirm these results.

Control of 24-hour blood pressure with SGLT2 inhibitors to prevent cardiovascular disease. Prog Cardiovasc Dis 2020; 63:249-262.

Abstract
The presence of hypertension (HTN) in patients with diabetes mellitus (DM) further worsens cardiovascular disease (CVD) prognosis. In addition, masked HTN and abnormal circadian blood pressure (BP) variability are common among patients with DM. Clinical trial data show that sodium-glucose cotransporter 2 inhibitors (SGLT2i) improve CVD prognosis and prevent progression of renal dysfunction in high-risk patients with type 2 DM (T2DM). Consistent reductions in 24-hour, daytime and nocturnal BP have been documented during treatment with SGLT2i in patients with DM and HTN, and these reductions are of a magnitude that is likely to be clinically significant. SGLT2i agents also appear to have beneficial effects on morning, evening and nocturnal home BP. Greater reductions in BP during treatment with SGLT2i have been reported in patient subgroups with higher body mass index, and in those with higher baseline BP. Other documented beneficial effects of SGLT2i include reductions in arterial stiffness and the potential to decrease the apnea-hypopnea index in patients with DM and obstructive sleep apnea. Recent guidelines highlight the important role of SGLT2i as part of the pharmacological management of patients with DM and HTN, and recommend consideration of SGLT2i early in the clinical course to reduce all-cause and CVD mortality in patients with T2DM and CVD. Overall, available data support a role for SGLT2i as effective BP-lowering agents in patients with T2DM and poorly controlled HTN, irrespective of baseline glucose control status. Sustained improvements in 24-hour BP and the 24-hour BP profile are likely to contribute to the CVD benefits of SGLT2i treatment.

Abstract
Today, excluding insulin, there are eight classes of anti-diabetic medicines that have been added to the pharmacy since the introduction of metformin in the mid-1950s; the sulfonylureas, biguanides, thiazolidinediones, α-glucosidase inhibitors, meglitinides, incretins, and sodium glucose transport 2 inhibitors. Does the fact that metformin is still first-line treatment suggest that our drug discovery efforts over the past 60 years have not been good enough? Or does it suggest that diabetes is such a complex disorder that no single treatment, other than gastric bypass surgery, can affect true normalization of not only blood sugar but also the underlying pathologies? Our understanding of the disease has most definitely improved which may bring hope for the future in terms of science, but for it to be beneficial, this science has to be translated into better drug treatments for the disease. In this review, I have examined the eight classes of anti-diabetes drugs from a drug discovery perspective.

Abstract
BACKGROUND Optimal glycemic control is required to restrain the increase of cardiovascular events in patients with type 2 diabetes. The effects of sodium-glucose cotransporter-2 (SGLT-2) inhibitors on cardiovascular events and mortality in those patients are not well established. This meta-analysis was conducted to assess the effects of SGLT2 inhibitors on cardiovascular events and mortality in patients with type 2 diabetes. METHODS We conducted a systematic literature search of Medline, Embase and Cochrane Library and included randomized controlled trials (RCTs) of 3 different SGLT2 inhibitors (canagliflozin, dapagliflozin and empagliflozin) that evaluated the effects on cardiovascular outcomes and mortality in the final meta-analysis. The intervention arm was defined either as SGLT2 inhibitor monotherapy or as SGLT2 inhibitor add-on to other non-SGLT2 inhibitor antidiabetic agents (ADAs). RESULTS Forty-two trials with a total of 61,076 patients with type 2 diabetes were included in the meta-analysis. Compared with the control, SGLT2 inhibitor treatment was associated with a reduction in the incidence of major adverse cardiovascular events (MACEs) (OR = 0.86, 95% CI 0.80-0.93, P < .0001), myocardial infarction (OR = 0.86, 95% CI 0.79-0.94, P = .001), cardiovascular mortality (OR = 0.74, 95% CI 0.67-0.81, P < .0001) and all cause mortality (OR = 0.85, 95% CI 0.79-0.92, P < .0001). However, the risk of ischemic stroke was not reduced after SGLT2 inhibitor treatment in patients with type 2 diabetes (OR = 0.95, 95% CI 0.85-1.07, P = .42). CONCLUSION These data suggest a decreased risk of harm with SGLT2 inhibitor as a class with respect to cardiovascular events and mortality.

Abstract
Sodium-glucose co-transporter 2 (SGLT2) inhibitors are glucose-lowering drugs that reduce plasma glucose levels by inhibiting glucose and sodium reabsorption in the kidneys, thus resulting in glucosuria. Their effects consequently include reductions in HbA1c, blood glucose levels, and blood pressure, but also reductions in body weight and adiposity. The ability to reduce body weight is consistently observed in individuals taking SGLT2 inhibitors, but this weight loss is moderate due to counter-regulatory mechanisms striving to maintain body weight. This has prompted exploration of SGLT2 inhibitors in combination with other agents acting via decreased food intake, e.g., glucagon-like peptide 1 receptor agonists (GLP1-RAs). The bodyweight effects are promising, and together with the signs of prevention of cardiovascular and renal events, such combinations including SGLT2 inhibitors are appealing. The weight loss is clinically important, as most individuals with type 2 diabetes are overweight or obese, but also because there is an unmet need for safe, effective, and durable weight loss interventions in obese individuals without diabetes.

Abstract
The prevalence of diabetes mellitus and heart failure is increasing. The novel sodium-glucose cotransporters 2 inhibitors offer multidimensional ameliorating effects on cardiovascular and heart failure risk factors. Several studies have assessed the impact on cardiovascular events, with data suggesting beneficial effects on cardiovascular events in high-risk patients with diabetes in patients with heart failure. The reverse J-curve pattern between blood pressure levels and mortality has emerged as an important topic in the field of heart failure. There is no significant evidence to propose any potential effect of sodium-glucose co-transporter 2 inhibitors on the J-shape-suggested mortality in patients with heart failure.

Abstract
Type 2 diabetes mellitus is a chronic metabolic disease associated with high cardiovascular (CV) risk. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are the latest class of antidiabetic medication that inhibit the absorption of glucose from the proximal tubule of the kidney and hence cause glycosuria. Four SGLT2i are currently commercially available in many countries: canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin. SGLT2i reduce glycated hemoglobin by 0.5%-1.0% and have shown favorable effects on body weight, blood pressure, lipid profile, arterial stiffness and endothelial function. More importantly, SGLT2i have demonstrated impressive cardioprotective and renoprotective effects. The main mechanisms underlying their cardioprotective effects have been attributed to improvement in cardiac cell metabolism, improvement in ventricular loading conditions, inhibition of the Na+/H+ exchange in the myocardial cells, alteration in adipokines and cytokines production, as well as reduction of cardiac cells necrosis and cardiac fibrosis. The main adverse events of SGLT2i include urinary tract and genital infections, as well as euglycemic diabetic ketoacidosis. Concerns have also been raised about the association of SGLT2i with lower limb amputations, Fournier gangrene, risk of bone fractures, female breast cancer, male bladder cancer, orthostatic hypotension, and acute kidney injury.

Abstract
Strict blood pressure (BP) control in patients with diabetes is associated with reductions in cardiovascular and renal risk. SGLT-2 inhibitors act in the proximal tubule to reduce glucose reabsorption. They also have mild natriuretic and diuretic effects, combining properties of proximal tubule diuretics and osmotic diuretics, which are expected to reduce BP. Several lines of evidence suggests that SGLT-2 inhibitors produce mild but meaningful reductions in BP and also decrease the incidence of renal outcomes, cardiovascular events and mortality. Thus, recent guidelines for type 2 diabetes suggest that among oral agents to use together with metformin, SGLT-2 inhibitors should be preferred in patients at increased cardiovascular risk, kidney disease or heart failure. This review summarizes current literature on the effect of SGLT-2 inhibitors on BP, and its potential relationships with cardio- and nephroprotection.

Abstract
The effectiveness of dapagliflozin in the management of type-2 diabetes mellitus (T2-DM) is an essential issue for establishing a basis for prescribing dapagliflozin. This study aimed to assess the effectiveness of dapagliflozin in combination with other hypoglycemic agents (OHAs) in reducing glycated hemoglobin (HbA1c) and fasting blood glucose (FBG) at 3, 6, 9 and 12 months. This retrospective observational study included all patients who visited the endocrine clinics at Hamad Medical Corporation (HMC) and were treated with dapagliflozin. Demographics and laboratory data were obtained retrospectively from computerized patient medical profiles (eMR-viewer). The main outcome measures were the differences in HbA1c and FBG from baseline at different months. Eighty-one Qatari patients were found to have received dapagliflozin during the study period; 72% of them (n = 58) were males, with a mean age of 57.0 ± 9.0 years and a mean baseline HbA1c of 9.0 ± 1.4%. Administration of dapagliflozin as an add-on therapy was found to decrease HbA1c significantly by 0.8 percentage point after 6 months (P = 0.006) and by 1.5 percentage point after 12 months (P = 0.062). FBG was significantly reduced at 6 months and 9 months (P = 0.001 and P = 0.03, respectively). Dapagliflozin effectively reduced the HbA1c level and FBG when used in combination with other OHAs or insulin within 6 to 12 months.

Abstract
AIMS We undertook a systematic review and meta-analysis to assess the efficacy and safety of sodium-glucose cotransporter 2 inhibitors (SGLT2is) concerning kidney outcomes in patients with type 2 diabetes mellitus (T2DM), with or without prevalent kidney disease. MATERIALS AND METHODS PubMed, Web of science, Embase and the Cochrane Library were systematically searched for randomized controlled trials (RCTs) to assess the efficacy and safety of treatment with SGLT2is versus placebo in patients with T2DM. The weighted mean difference (WMD) and its 95% confidence interval (CI) were applied for continuous variables, and the risk ratio (RR) and corresponding 95% CI were used for dichotomous outcomes. Patients were categorized according to whether the baseline mean estimated glomerular filtration rate (eGFR) was less or was more than 60 mL/min/1.73 m2 . RESULTS A total of 25 eligible studies with 43 721 participants were included. There was an initial and small decrease in eGFR during the early treatment period (WMD, -4.63; 95% CI, -6.08 to -3.19 mL/min/1.73 m2 ), which was noted at 1-6 weeks and gradually narrowed over time, with a decline in protection from eGFR in the long term (WMD, 3.82; 95% CI, 2.80-4.85 mL/min/1.73 m2 ). SGLT2is significantly delayed albuminuria progression (RR, 0.71; 95% CI, 0.66-0.76), promoted albuminuria regression (RR,1.71; 95% CI, 1.54-1.90), improved the composite of ≥40% decrease in eGFR, in the need for renal-replacement and in death from renal causes (RR, 0.57; 95% CI, 0.49-0.66), and reduced all-cause mortality (RR, 0.84; 95% CI, 0.75-0.94). At the same time, they significantly increased the risk of genital infection (RR, 3.43; 95% CI, 2.87-4.10) vs placebo in patients with T2DM. Meta-regression analyses showed that eGFR-preservation effects were not significantly associated with basic patient characteristics (age, BMI, HbA1c, eGFR level), but were influenced by drug administration (treatment duration, type, dosage of SGLT2is). Subgroup analyses showed that the relative effects on renal outcomes of SGLT2is vs placebo were similar across eGFR subgroups (P heterogeneity >0.05). CONCLUSIONS SGLT2is slowed eGFR decline, lowered albuminuria progression, improved adverse renal endpoints and reduced all-cause mortality, but increased risk of genital infections vs placebo in patients with T2DM. The indication of consistent renal benefits across categories of baseline eGFR levels may allow additional individuals to benefit from SGLT2is therapy.

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
OBJECTIVE To estimate the association between the use of sodium glucose co-transporter-2 (SGLT2) inhibitors and postmarket harms as identified by drug regulatory agencies. DESIGN We conducted a systematic review and meta-analysis of randomised controlled trials (RCT). Six large databases were searched from inception to May 2018. Random effects models were used to estimate pooled relative risks (RRs). INTERVENTION SGLT2 inhibitors, compared with placebo or active comparators. PRIMARY OUTCOMES Acute kidney injury (AKI), diabetic ketoacidosis (DKA), urinary tract infections (UTI), bone fractures and lower limb amputations. RESULTS We screened 2418 citations of which 109 were included. Most studies included one of four SGLT2 inhibitors, dapagliflozin, canagliflozin, empagliflozin and ipragliflozin. When compared with placebo, SGLT2 inhibitors were found to be significantly protective against AKI (RR=0.59; 95% CI 0.39 to 0.89; I2=0.0%), while no difference was found for DKA (RR 0.66; 95% CI 0.30 to 1.45, I2=0.0%), UTI (RR 1.02; 95% CI 0.95 to 1.09, I2=0.0%) or bone fracture (RR 0.87; 95% CI 0.69 to 1.09, I2=1.3%). Three studies reported on amputation, with one finding a significant increase risk. No increased risk for either outcome was found when compared with active controls. Subgroup analysis did show an increased risk of UTI with dapagliflozin only (RR 1.21; 95% CI 1.02 to 1.43, I2=0.0%), but no other analysis supported an increased risk of AKI, DKA, UTI or fracture. CONCLUSIONS Current evidence from RCTs does not suggest an increased risk of harm with SGLT2 inhibitors as a class over placebo or active comparators with respect to AKI, DKA, UTI or fracture. However, wide CIs for many comparisons suggest limited precision, and therefore clinically important adverse events cannot be ruled out. Dapagliflozin, appears to independently increase the risk of UTI, although the mechanism for this intraclass variation in risk is unclear. PROSPERO REGISTRATION NUMBER CRD42016038715.

Abstract
Type 2 diabetes mellitus (T2DM) is a family of metabolic disorders characterized by hyperglycemia as a consequence of abnormalities in insulin secretion and insulin sensitivity. It affects hundreds of millions of people worldwide and leads to increased morbidity, compromised quality of life, higher mortality sodium glucose co-transporter 2 (SGLT2) inhibitors, a new class of oral antidiabetic drugs, have garnered considerable attention in the recent past and are considered potential first-line candidates for the management of T2DM. This review outlines the evidence-based therapeutic efficacy, safety, limitations, and advantages of SGLT2 inhibitors in the management of T2DM. SGLT2 inhibitors work by preventing the kidneys from reabsorbing glucose back into the blood, leading to increase in excretion of glucose through urine, thereby lowering hyperglycemia. Treatment with SGLT2 inhibitors improves A1C levels, reduces blood pressure and body weight, and is overall well tolerated by patients with T2DM. However, additional data on long-term cardiovascular safety are still needed. Characteristic adverse events include mild genital - urinary tract infection more commonly seen in women than in men, but serious infection is uncommon. Their use should be exercised with extra caution in patients suffering from renal impairment. Further, advancing to dual/triple combinational therapies with SGLT2 inhibitors and existing oral antidiabetic options may prove to be a breakthrough in the management of T2DM.

Comparison of antidiabetic drugs added to sulfonylurea monotherapy in patients with type 2 diabetes mellitus: A network meta-analysis. PLoS One 2018; 13:e0202563. [PMID: 30148851 PMCID: PMC6110472 DOI: 10.1371/journal.pone.0202563] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Accepted: 08/06/2018] [Indexed: 12/23/2022] Open
Abstract
AIMS This study aimed to investigate the efficacy and safety of dual therapy comprising sulfonylurea (SU) plus antidiabetic drugs for the treatment of type 2 diabetes mellitus (T2DM). METHODS We searched the PubMed, Cochrane library, and Embase databases for randomized clinical trials (≥24 weeks) published up to December 28, 2017. Subsequently, we conducted pairwise and network meta-analyses to calculate the odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs) of the outcomes. RESULTS The final analyses included 24 trials with a total of 10,032 patients. Compared with placebo, all treatment regimens were associated with a significantly higher risk of hypoglycemia, except the combinations of SU plus sodium-glucose co-transporter-2 inhibitor (SGLT-2i) [OR, 1.35 (95% CI: 0.81 to 2.25)] or alpha-glucosidase inhibitor (AGI) [OR, 1.16 (95% CI: 0.55 to 2.44)]. Notably, the combination of SU plus glucagon-like peptide-1 receptor agonist (GLP-1RA) was associated with the most significant increase in the risk of hypoglycemia. Furthermore, all SU-based combination regimens reduced the glycated hemoglobin (HbA1c) and fasting plasma glucose levels (FPG). However, only combinations containing SGLT-2i [MD, -1.00 kg (95% CI: -1.73 to -0.27)] and GLP-1RA [MD, -0.56 kg (95% CI: -1.10 to -0.02)] led to weight loss. CONCLUSIONS Our findings highlight the importance of considering the risk of hypoglycemia when selecting antidiabetic drugs to be administered concomitantly with SU. Although all classes of antidiabetic drugs improved glucose control when administered in combination with SU, SGLT-2i might be the best option with respect to factors such as hypoglycemia and body weight.

Abstract
BACKGROUND Most people with type 2 diabetes are overweight, so initial treatment is aimed at reducing weight and increasing physical activity. Even modest weight loss can improve control of blood glucose. If drug treatment is necessary, the drug of first choice is metformin. However, some people cannot tolerate metformin, which causes diarrhoea in about 10%, and it cannot be used in people with renal impairment. This review appraises three of the newest class of drugs for monotherapy when metformin cannot be used, the sodium-glucose co-transporter 2 (SGLT2) inhibitors. OBJECTIVE To review the clinical effectiveness and cost-effectiveness of dapagliflozin (Farxiga, Bristol-Myers Squibb, Luton, UK), canagliflozin (Invokana, Janssen, High Wycombe, UK) and empagliflozin (Jardiance, Merck & Co., Darmstadt, Germany), in monotherapy in people who cannot take metformin. SOURCES MEDLINE (1946 to February 2015) and EMBASE (1974 to February 2015) for randomised controlled trials lasting 24 weeks or more. For adverse events, a wider range of studies was used. Three manufacturers provided submissions. METHODS Systematic review and economic evaluation. A network meta-analysis was carried out involving the three SGLT2 inhibitors and key comparators. Critical appraisal of submissions from three manufacturers. RESULTS We included three trials of dapagliflozin and two each for canagliflozin and empagliflozin. The trials were of good quality. The canagliflozin and dapagliflozin trials compared them with placebo, but the two empagliflozin trials included active comparators. All three drugs were shown to be effective in improving glycaemic control, promoting weight loss and lowering blood pressure (BP). LIMITATIONS There were no head-to-head trials of the different flozins, and no long-term data on cardiovascular outcomes in this group of patients. Most trials were against placebo. The trials were done in patient groups that were not always comparable, for example in baseline glycated haemoglobin or body mass index. Data on elderly patients were lacking. CONCLUSIONS Dapagliflozin, canagliflozin and empagliflozin are effective in improving glycaemic control, with added benefits of some reductions in BP and weight. Adverse effects are urinary and genital tract infections in a small proportion of users. In monotherapy, the three drugs do not appear cost-effective compared with gliclazide or pioglitazone, but may be competitive against sitagliptin (Januvia, Boehringer Ingelheim, Bracknell, UK).

Abstract
Revelations of the multifactorial pathogenesis of type 2 diabetes mellitus (T2DM) that extend beyond the role of insulin and glucose utilization have been crucial in redefining the treatment paradigm. The focus of treatment is currently directed towards achieving wide-ranging targets encompassing the management of cardiovascular comorbidities that have been evidenced as indispensable aspects of T2DM. While most currently prescribed antihyperglycemic agents have little or no effect on reducing cardiovascular risks, some have been associated with undesirable effects on common risk factors such as weight gain and cardiovascular sequelae. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are newer additions to the array of therapeutic agents for T2DM that have demonstrated robust glycemic control as mono and add-on therapies. Their unique renal mode of action, independent of insulin modulation, confers complementary metabolic benefits. By virtue of these effects, SGLT2i may have a distinct role in the revised treatment recommendations by established working groups such as the American Diabetes Association and the American Association of Clinical Endocrinologists that advocate a more comprehensive management of T2DM, not restricting to glycemic targets. The current review gives an overview of the changing treatment needs for T2DM and discusses the nonglycemic effects of SGLT2i. It provides an updated summary on the efficacy of canagliflozin, dapagliflozin, and empagliflozin in promoting weight loss, stabilizing blood pressure, and other favorable metabolic effects.

Abstract
BACKGROUND Due to the chronic nature of type 2 diabetes (T2D), it is essential for an anti-diabetic drug to have durable efficacy and a good long-term safety profile. Dapagliflozin is a member of a unique class of anti-diabetic drugs that inhibit the sodium-glucose cotransporter 2 (SGLT-2) in the renal tubules and have an insulin-independent mechanism of action. In short-term studies (≤ 24 weeks), dapagliflozin reduced glycated hemoglobin (A1c), weight, and systolic blood pressure, and had a good safety profile. METHODS This review summarizes the findings of long-term studies that evaluated the efficacy and safety of dapagliflozin. RESULTS These findings indicate that dapagliflozin is effective as monotherapy and in combination with other anti-hyperglycemic agents, including insulin and oral anti-diabetic therapies, in improving glycemic control and reducing blood pressure and weight for up to 4 years. The findings were fairly consistent across various patient populations with T2D, including those with cardiovascular disease (CVD) and mild renal impairment. Extended use of dapagliflozin was not associated with an increase in safety signals over time. Frequently observed adverse events (AEs) were consistent with the drug's mechanism of action and were generally mild in intensity. No substantial impact of dapagliflozin on renal function was observed, and findings show that the drug is safe in T2D patients with CVD or mild renal impairment, as well as elderly patients. CONCLUSIONS The findings across the studies support the use of dapagliflozin for the long-term treatment of T2D across a broad spectrum of patients.

Abstract
BACKGROUND The efficacy and safety of dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, has been demonstrated predominantly in Western populations. This study examined the efficacy and safety of dapagliflozin in Asian patients with type 2 diabetes mellitus (T2DM) from eight Phase IIb/III double-blind trials of up to 24 weeks, treated with placebo (n = 497) or dapagliflozin 5 mg (n = 491) or 10 mg (n = 465). METHODS Efficacy was assessed in the pooled population receiving dapagliflozin 5, 10 mg or placebo over 24 weeks. Safety and tolerability were assessed by collating data for overall adverse events (AEs) and AEs of special interest over the 24-week period. RESULTS Demographic and baseline characteristics were comparable across treatment groups. Placebo-corrected adjusted mean changes from baseline at 24 weeks in the dapagliflozin 5 and 10 mg groups, respectively, were -0.52% and -0.58% for HbA1c and -1.34 and -1.80 kg for body weight. Modest reductions in blood pressure were also noted with dapagliflozin. Overall, 56.5%, 53.6%, and 58.7% of patients in the placebo and dapagliflozin 5 and 10 mg groups, respectively, experienced AEs, compared with 2.8%, 4.1%, and 2.4% experiencing serious AEs. Genital infections were more frequent with dapagliflozin 10 mg than placebo, whereas the pattern for urinary tract infections was less clear. A transient reduction in mean estimated glomerular filtration rate was noted with dapagliflozin, but was not associated with an increased frequency of serious renal AEs. In contrast, placebo-corrected reductions in urinary albumin : creatinine ratio in patients with albuminuria at baseline suggest a potential renoprotective effect of dapagliflozin. CONCLUSION Dapagliflozin was efficacious and well tolerated in Asian patients with T2DM.

Abstract
INTRODUCTION The present review developed a clinical consensus based on a Delphi method on Dapagliflozin, a selective inhibitor of the renal sodium-glucose co-transporter-2 (SGLT2-I) in the treatment of patients with Type 2 diabetes mellitus. Areas covered: Panel members, using a 5-point scale, were asked to rate 9 statements on pharmakodinamic, mode of action on glycaemic and extra-glycaemic effects, and safety of dapaglifozin, Members also aimed to identify the patient most susceptible to the treatment with dapagliflozin . Expert commentary: Dapagliflozin is effective in lowering the plasma glucose concentration with a good safety profile. Dapagliflozin can be utilized in combination with all other antihyperglycaemic agents at all stages of the disease: however, a reduced GFR limits its efficacy. As for the other drugs of the class, Dapagliflozin positively modifies other risk factors for CV disease: these effects will be tested in the so far largest cardiovascular outcome trial for the SGLT2 inhibitors so far, the DECLARE trial, which will communicate whether this class of drugs will be disease-modifier in patients with type 2 diabetes also in primary prevention.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors (gliflozins) are the newest class of medication available to treat type 2 diabetes (T2DM). Recent findings from the first complete cardiovascular safety trial in SGLT2 inhibitors, the Empagliflozin, Cardiovascular Outcomes, and Mortality in type 2 diabetes (EMPA-REG OUTCOMES) trial, demonstrated reduced cardiovascular outcomes in people with high cardiovascular risk. How to apply these findings to clinical practice remains unclear, with questions remaining on who will reap this cardiovascular benefit. AIM To describe the proportion of people in the real world currently treated with SGLT2 inhibitors who meet the inclusion criteria of the EMPA-REG trial and therefore could expect the cardiovascular benefit identified by the trial. Similarly, to describe the proportion of people from the whole T2DM population who could also expect this same benefit. DESIGN AND SETTING Routinely collected data from UK primary care in the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) database will be used. The study population will include all people with T2DM within this database (approximately 60,000). We will perform a cross-sectional investigation to describe the characteristics of people currently using SGTL2 inhibitors compared with the population of the EMPA-REG trail. We will similarly compare the characteristics of the RCGP RSC T2DM cohort with the inclusion criteria of the EMPA-REG trial. METHOD People with T2DM using a pre-existing verified clinical ontological process will be identified, as will people with prescriptions for SGLT2 inhibitors and other medications using Read coded and other proprietary coding systems. Descriptive statistics will be used to characterise the key clinical characteristics of people with T2DM using SGLT2 inhibitors and to compare these characteristics to people included in EMPA-REG trial; the proportion of people who match the trial criteria will be reported. PLANNED OUTPUTS Peer review publication reporting the real world lessons for clinical practice. FUNDING AstraZeneca.

Abstract
INTRODUCTION Diabetic kidney disease is the leading cause of end-stage renal disease, a significant contributor to cardiovascular (CV) disease, responsible for much of the morbidity and mortality in patients with type 2 diabetes (T2DM). Strategies to slow or prevent the onset and progression of diabetic kidney disease are critical for effectively managing T2DM and reducing CV risk. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are effective antidiabetic agents, which may provide nephroprotective and CV protective effects. Areas covered: This review examines the role of the kidney in glucose homeostasis, discusses renal hemodynamic changes in diabetes, and outlines the major hypotheses regarding the mechanisms underlying renal injury in diabetes. The potential benefits of SGLT2 inhibitors in the prevention and treatment of CV complications in patients with T2DM are reviewed, with particular focus on dapagliflozin. Expert opinion: Dapagliflozin and other SGLT2 inhibitors have the capacity to decrease hyperglycemia and visceral fat, components of the metabolic syndrome particularly associated with the progression of CV disease. However, the mechanisms of action of SGLT2 inhibitors resulting in their positive CV effects remain unclear. Furthermore, the mechanism of action of SGLT2 inhibitors on heart function in non-diabetic patients with decompensated heart failure remains to be explored.

Abstract
AIMS The aim of this article is to review the safety and efficacy data of dapagliflozin, saxagliptin, and their combination in the management of patients with type 2 diabetes. Evidence for the use of the single-tablet combination formulation is also presented. METHODS A nonsystematic literature review was performed using the Ovid, PubMed, and Google Scholar databases. RESULTS The addition of dapagliflozin/saxagliptin to metformin can lower mean hemoglobin A1c by as much as 1.47% and lead to weight loss of 0.5-2.0 kg. The risk of genital infections with combination therapy is lower than observed with dapagliflozin alone, suggestive of a protective effect. Adverse event risk at 52-week follow-up was not increased beyond that seen with either monotherapy. CONCLUSION Dapagliflozin/saxagliptin combination is generally well tolerated and is an effective tool in helping patients with diabetes improve glycemic control.

Abstract
In the last ten years, knowledge on pathophysiology of type 2 diabetes (T2DM) has significantly increased, with multiple failures (decreased incretin effect, increased lipolysis, increased glucagon secretion, neurotransmitters dysfunction) recognized as important contributors, together with decreased insulin secretion and reduced peripheral glucose uptake. As a consequence, the pharmacologic therapy of T2DM has been progressively enriched by several novel classes of drugs, trying to overcome these defects. The last, intriguing compounds come into the market are SGLT2 inhibitors, framing the kidney in a different scenario, not as site of a harmful disease complication, but rather as the means to correct hyperglycemia and fight the disease. This review aims to offer a short, updated overview of the role of these compounds in the treatment of T2DM, focusing on efficacy, ancillary albeit relevant clinical effects, safety, potential cardiovascular protection, positioning in common therapeutic algorithms.

Abstract
OBJECTIVE Sodium-glucose co-transporter 2 inhibitors (SGLT2-i) are a novel drug class for the treatment of diabetes. We aimed at describing the maximal benefits and risks associated with SGLT2-i for patients with type 2 diabetes. DESIGN Systematic review and meta-analysis. DATA SOURCES AND STUDY SELECTION We included double-blinded, randomised controlled trials (RCTs) evaluating SGLT2-i administered in the highest approved therapeutic doses (canagliflozin 300 mg/day, dapagliflozin 10 mg/day, and empagliflozin 25 mg/day) for ≥12 weeks. Comparison groups could receive placebo or oral antidiabetic drugs (OAD) including metformin, sulphonylureas (SU), or dipeptidyl peptidase 4 inhibitors (DPP-4-i). Trials were identified through electronic databases and extensive manual searches. Primary outcomes were glycated haemoglobin A1c (HbA1c) levels, serious adverse events, death, severe hypoglycaemia, ketoacidosis and CVD. Secondary outcomes were fasting plasma glucose, body weight, blood pressure, heart rate, lipids, liver function tests, creatinine and adverse events including infections. The quality of the evidence was assessed using GRADE. RESULTS Meta-analysis of 34 RCTs with 9,154 patients showed that SGLT2-i reduced HbA1c compared with placebo (mean difference -0.69%, 95% confidence interval -0.75 to -0.62%). We downgraded the evidence to 'low quality' due to variability and evidence of publication bias (P = 0.015). Canagliflozin was associated with the largest reduction in HbA1c (-0.85%, -0.99% to -0.71%). There were no differences between SGLT2-i and placebo for serious adverse events. SGLT2-i increased the risk of urinary and genital tract infections and increased serum creatinine, and exerted beneficial effects on bodyweight, blood pressure, lipids and alanine aminotransferase (moderate to low quality evidence). Analysis of 12 RCTs found a beneficial effect of SGLT2-i on HbA1c compared with OAD (-0.20%, -0.28 to -0.13%; moderate quality evidence). CONCLUSION This review includes a large number of patients with type 2 diabetes and found that SGLT2-i reduces HbA1c with a notable increased risk in non-serious adverse events. The analyses may overestimate the intervention benefit due bias.

Abstract
AIMS To review prevalence and significance of urinary tract (UTI) and genital infections (GI) in diabetes and the effects of sodium glucose cotransporter 2 (SGLT-2) inhibitors on these complications. DATA SYNTHESIS The prevalence of asymptomatic bacteriuria (ASB) is 2-3 times higher in diabetic than in non-diabetic women. The treatment of ASB has no impact on the development of UTIs and/or a decline in renal function. Therefore, there is no indication for screening for and/or treatment of ASB. The incidence of UTI is higher and frequently complicated in diabetic patients, particularly in those with longer duration of disease and of older age. There is no consistent evidence of an association between A1c levels, glycosuria and the risk of ASB and/or UTIs. Diabetes is a known risk factor for Candida colonization and GI, and a poor glycemic control is associated with a higher risk. While patients treated with SGLT-2 inhibitors may have a non-significant increased risk of UTI, they have a clearly increased risk of GI; most of these infections are mild, easy to treat, and the rate of recurrence is low. CONCLUSION Diabetic patients are at high risk of UTIs and of GI. Only GI are associated with poor glycemic control. Although patients treated with SGLT-2 inhibitors have an increased 3-5 fold risk of GI, proper medical education can reduce this risk.

Abstract
Objectives. To observe changes in blood glycemic variations and oxidative stress level before and after dapagliflozin treatment in patients with newly diagnosed T2DM. Methods. This was a randomized, double-blind, placebo-controlled, phase 3 trial. A total of 28 patients with newly diagnosed T2DM with HbA1c levels of 7.5-10.5% were randomly selected to receive dapagliflozin or placebo treatment for 24 weeks. After baseline data were collected, we analyzed glycemic variations and plasma 8-iso PGF2α level at baseline and at the endpoint. Primary outcome was the changes of mean amplitude glycemic excursion (MAGE) within groups. Results. After 24-week dapagliflozin therapy, our data showed the significant improvement of MAGE with dapagliflozin therapy (P = 0.010). Compared with control group, patients in dapagliflozin group exhibited reduction in 24-hour MBG (P = 0.026) and lower mean plasma glucose concentrations, especially during periods from 2400 to 0200 and 1300 to 1800 (P < 0.05, resp.). In addition, plasma 8-iso PGF2α level was notably decreased in the treatment group compared to the control group (P = 0.034). Conclusions. In conclusion, this study shows the ability of dapagliflozin to improve glycemic variations and associate with reduction of oxidative stress in patients with T2DM, which may benefit the cardiovascular system.

Efficacy and safety of sodium-glucose co-transporter-2 inhibitors in type 2 diabetes mellitus: systematic review and network meta-analysis. Diabetes Obes Metab 2016; 18:783-94. [PMID: 27059700 DOI: 10.1111/dom.12670] [Citation(s) in RCA: 320] [Impact Index Per Article: 40.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2016] [Revised: 03/24/2016] [Accepted: 03/31/2016] [Indexed: 12/13/2022]
Abstract
AIM To assess the comparative efficacy and safety of sodium-glucose co-transporter-2 (SGLT2) inhibitors in adults with type 2 diabetes. METHODS We electronically searched randomized controlled trials (≥24 weeks) including canagliflozin, dapagliflozin or empagliflozin that were published up to 3 November 2015. Data were collected on cardiometabolic and safety outcomes and synthesized using network meta-analyses. RESULTS A total of 38 trials (23 997 participants) were included. Compared with placebo, all SGLT2 inhibitors reduced glycated haemoglobin (HbA1c), fasting plasma glucose (FPG), body weight and blood pressure, and slightly increased HDL cholesterol. Canagliflozin 300 mg reduced HbA1c, FPG and systolic blood pressure and increased LDL cholesterol to a greater extent compared with other inhibitors at any dose. At their highest doses, canagliflozin 300 mg reduced: HbA1c by 0.2% [95% confidence interval (CI) 0.1-0.3] versus both dapagliflozin 10 mg and empagliflozin 25 mg; FPG by 0.6 mmol/l (95% CI 0.3-0.9) and 0.5 mmol/l (95% CI 0.1-0.8) versus dapagliflozin and empagliflozin, respectively; and systolic blood pressure by 2 mmHg (95% CI 1.0-3.0) versus dapagliflozin; and increased LDL cholesterol by 0.13 mmol/l (95% CI 0.03-0.23) and 0.15 mmol/l (95% CI 0.06-0.23) versus dapagliflozin and empagliflozin, respectively. The highest doses of inhibitors had similar effects on body weight reduction. Canagliflozin 300 and 100 mg increased the risk of hypoglycaemia versus placebo, dapagliflozin 10 mg and empagliflozin 10 mg [odds ratios (ORs) 1.4-1.6]. Dapagliflozin 10 mg increased the risk of urinary tract infection versus placebo and empagliflozin 25 mg (ORs 1.4). All inhibitors similarly increased the risk of genital infection (ORs 4-6 versus placebo). CONCLUSIONS Although they increase the risk of genital infection, SGLT2 inhibitors are effective in improving cardiometabolic markers in type 2 diabetes, with canagliflozin 300 mg performing better in this respect than other inhibitors. Further studies will clarify whether these differences are likely to translate into differing long-term outcomes.

Abstract
AIM To evaluate the long-term efficacy, safety and tolerability of dapagliflozin versus placebo added to usual care in patients with type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). METHODS Data were pooled from two phase III studies (NCT01031680 and NCT01042977) in high-risk patients (N = 1887) with T2DM and CVD treated with dapagliflozin (10 mg/day) or placebo. Patients completing the double-blind treatment studies (24 weeks) entered one or two sequential double-blind, long-term (LT) extensions of 28 (LT1; n = 1649) and 52 (LT2; n = 568) weeks. RESULTS Baseline and CVD characteristics were similar in the two groups. Patients entering LT1 and LT2 on dapagliflozin maintained a greater mean reduction in glycated haemoglobin (HbA1c) versus placebo at 52 weeks [LT1, -0.58% (95% confidence interval -0.68, -0.49)] and 104 weeks [LT2, -0.35% (95% confidence interval -0.59, -0.12)]. Mean body weight and systolic blood pressure (SBP) reductions versus placebo were maintained in patients entering LT1 (52 weeks; -2.23 kg and -3.25 mmHg, respectively) and LT2 (104 weeks; -3.16 kg and -2.03 mmHg, respectively). Patients on dapagliflozin had a better three-item composite endpoint of clinical benefit (glycaemia, weight and SBP) compared with placebo at week 24 (LT1, 10.1% vs. 1.1%) and week 104 (LT2, 6.7% vs. 1.4%). Genital and urinary tract infections were more frequent with dapagliflozin than with placebo. Events of hypoglycaemia, renal impairment/failure and volume depletion were similar between groups. CONCLUSIONS The long-term efficacy of dapagliflozin to maintain reductions in HbA1c, SBP and body weight over 2 years, together with its tolerability profile, make dapagliflozin an appropriate option in high-risk patients with T2DM and CVD.

Abstract
Diabetes mellitus is a major issue of public health, affecting more than 300 million people worldwide. Inhibitors of the sodium-glucose cotransporter-2 (SGLT-2) in the renal proximal tubule are a novel class of agents for the treatment of type 2 diabetes mellitus. Inhibition of the SGLT-2 results in reduced glucose reabsorption and improvement in glycemic control. Alongside glucose excretion, SGLT-2 inhibitors also have mild natriuretic and diuretic effects, combining actions of a proximal tubule diuretic and an osmotic diuretic; these properties are expected to lead to small blood pressure (BP) reductions. Clinical studies with dapagliflozin, canagliflozin, empagliflozin, ipragliflozin, luseogliflozin, and tofogliflozin used either as monotherapy or add-on therapy and compared with placebo or active treatment have also examined the effect of these agents on BP as a secondary endpoint. Although with some differences between individual agents, all of the approved SGLT-2 inhibitors provided a mild but meaningful reduction in office SBP and DBP. Recent studies with the use of ambulatory blood pressure monitoring suggest that the magnitude of this BP reduction can be even greater. The aim of this review is to systematically summarize and present the studies reporting the effect of approved SGLT-2 inhibitors on BP.

Abstract
AIMS The size of the placebo response in type 2 diabetes (T2DM) treatment and its relation to the route of drug administration have not been systematically reviewed. We aimed to determine weight loss, change in HbA1c and incidence of adverse events after treatment with injectable placebo GLP-1 receptor agonist (GLP-1ra), compared with oral placebo DPP-4 inhibitor (DPP-4i) and placebo SGLT-2 inhibitor (SGLT-2i). METHODS PubMed, EMBASE and Central were searched up to September 2014 for randomized placebo controlled trials investigating GLP-1ra, DPP-4i or SGLT2-i. Data on placebo groups were extracted and pooled using a generic inverse variance random effects model. RESULTS Sixty-seven trials were included, involving 2522, 5290 and 2028 patients randomized to placebo GLP-1ra, placebo DPP-4i and placebo SGLT-2i, respectively. Body weight decreased by -0.67 kg (95% CI -1.03, -0.31) after treatment with placebo GLP-1ra (-0.76 kg [95% CI -1.10, -0.43] with placebo short acting GLP-1ra and -0.32 kg [95% CI -1.75, 1.10] with placebo long acting GLP-1ra) and by -0.31 kg (95% CI -0.64, 0.01) with placebo DPP-4i (P = 0.06 for difference with placebo short acting GLP-1ra). Placebo SGLT-2i resulted in an intermediate -0.48 kg (95% CI -0.81, -0.15) weight loss. Weight loss with placebo showed a strong correlation with the active comparator drug (r(2) = 0.40-0.78). HbA1c changed little with placebo treatment (-0.23%, 0.10% and -0.13% for placebo GLP-1ra, DPP-4i and SGLT-2i). Adverse events occurred frequently with placebo, were often similar to the active comparator drug and led to drop-out in 2.0-2.7% of cases. CONCLUSIONS The response to placebo treatment was related to its active comparator, with injectable placebo GLP-1ra showing a relevant response on weight, whereas oral placebo DPP4i showed no significant response. These findings may suggest that subjective expectations influence T2DM treatment efficacy, which can possibly be employed therapeutically.

Abstract
INTRODUCTION Sodium glucose co-transporter 2 (SGLT2) inhibitors such as dapagliflozin and dipeptidyl peptidase-4 (DPP-4) inhibitors such as saxagliptin have the potential to confer significant benefits in glycemic control without the risk of weight gain and hypoglycemia, which may be associated with other medications used to treat type 2 diabetes. AREAS COVERED This review examines the current available literature on the combination of saxagliptin and dapagliflozin as a treatment option, which is likely to be available as a fixed-dose combination in 2016. We reviewed the available published literature along with recently published abstracts examining the combination of these agents in relation to glycemic control, weight and blood pressure reduction, and adverse effects. EXPERT OPINION To date, the limited literature suggests that the combination of saxagliptin and dapagliflozin is associated with significant improvements in glycated haemoglobin, fasting and postprandial glucose levels with few adverse effects. The combination appears to be well tolerated with low rates of hypoglycemia, urinary tract, and genital infections. Combination therapy may also be associated with improved beta-cell function and enhanced insulin clearance in addition to their established underlying mechanisms of action. Further publications of ongoing trials and abstracts should further support its clinical role.
