Tuersun A, Hou G, Cheng G. Efficacy and Safety of the Combination or Monotherapy With GLP-1 Receptor Agonists and SGLT-2 Inhibitors in Type 2 Diabetes Mellitus: An update Systematic Review and Meta-analysis. Am J Med Sci 2024:S0002-9629(24)01348-X. [PMID: 38977245 DOI: 10.1016/j.amjms.2024.07.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 07/03/2024] [Accepted: 07/03/2024] [Indexed: 07/10/2024]
Abstract
PURPOSE To evaluate the efficacy and safety of combination therapy with sodium-glucose cotransporter2(SGLT-2) inhibitors and glucagon-like peptide-1(GLP-1) receptor agonists in the treatment of type 2 diabetes mellitus (T2DM). METHODS To construct an exhaustive database of randomized controlled trials (RCTs) concerning SGLT-2 inhibitors and GLP-1 agonists, a methodical search was undertaken across a range of databases, such as Embase, PubMed, and the Cochrane Central Register of Controlled Trials, from their inception to January 2023. Following this, a meta-analysis was executed to amalgamate the collected data, which allowed for the calculation of standardized mean differences (SMDs), odds ratios (ORs), and 95% confidence intervals (CIs) for a spectrum of outcomes. This analytical approach was designed to yield a quantitative evaluation of the therapeutic efficacy and safety profile of SGLT-2 inhibitors and GLP-1 agonists for the treatment of diabetes mellitus. RESULTS When compared to GLP-1 agonist therapy alone, the combination therapy did not significantly reduce fasting plasma glucose (FPG) levels (95% confidence interval [CI]: -0.27, 0.10; p=0.35), body weight (95% CI: -0.18, 0.18; p=1.00), Glycosylated Hemoglobin, Type A1C (HbA1c) (95% CI: -0.29, 0.07; p=0.22), or systolic blood pressure (SBP) values (95% CI: -0.29, 0.06; p=0.21). In contrast, when compared to SGLT-2 inhibitor therapy alone, combination therapy significantly decreased FPG by 0.24 mmol/L (95% CI: -0.43, -0.05; p=0.01), HbA1c by 0.45% (95% CI: -0.72, -0.18; p=0.001), and SBP by 0.12 mmHg (95% CI: -0.24, 0.00; p=0.05). However, the combination therapy failed to demonstrate a significant reduction in body weight when compared with either SGLT-2 inhibitor therapy (95% CI: -0.20, 0.05; p=0.24) or GLP-1 agonist therapy (95% CI: -0.18, 0.18; p=1.00). Additionally, the combination therapy did not increase the incidence of hypoglycemia. It should be noted that data regarding mortality and cardiovascular outcomes were limited. CONCLUSIONS The combination treatment of SGLT-2 inhibitors and GLP-1 receptor agonists effectively reduces HbA1c, FPG, and SBP without elevating the risk of hypoglycemia when compared to monotherapy with SGLT-2 inhibitors. However, these beneficial effects were not observed when the combination therapy was compared with GLP-1 receptor agonist treatment alone.

Diabetes Obes Metab 2024; 26:1624-1635. [PMID: 38240066 DOI: 10.1111/dom.15464] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 01/04/2024] [Accepted: 01/05/2024] [Indexed: 04/09/2024]
Abstract
AIM Despite the increasing use of combination treatment with sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists, data are limited on the effects of combination treatment on markers of cardiovascular disease. This study aimed to investigate the effect of empagliflozin, semaglutide, and their combination on vascular function. MATERIALS AND METHODS In total, 120 patients with type 2 diabetes were randomized into four groups (n = 30 in each) for 32 weeks: placebo, semaglutide, empagliflozin, and their combination. The study had two co-primary outcomes: change in arterial stiffness and kidney oxygenation. This paper reports on arterial stiffness assessed as carotid-femoral pulse wave velocity. Secondary outcomes included 24-h blood pressure (BP), 24-h central BP, urinary albumin to creatinine ratio and glycaemic control assessed by both continuous glucose monitoring and glycated haemoglobin. RESULTS The carotid-femoral pulse wave velocity did not change significantly in any of the groups compared with placebo. Twenty-four-hour systolic BP was reduced by 10 mmHg (95% CI 6-14), p < .001 in the combination group, significantly superior to both placebo and monotherapy (p < .05). Combination treatment increased glycaemic time in range from 72% at baseline to 91% at week 32, p < .001, without increasing time below range. The urinary albumin to creatinine ratio decreased by 36% (95% CI 4-57), p = .03 in the combination group compared with placebo. CONCLUSIONS Empagliflozin, semaglutide, or their combination did not reduce arterial stiffness. Combination treatment showed a substantial and clinically important reduction in 24-h systolic BP compared with either treatment alone. Combination treatment increased glycaemic time in range without increasing the risk of hypoglycaemia.

Restoration of blood vessel regeneration in the era of combination SGLT2i and GLP-1RA therapy for diabetes and obesity. Cardiovasc Res 2024; 119:2858-2874. [PMID: 38367275 DOI: 10.1093/cvr/cvae016] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 12/20/2022] [Accepted: 01/05/2023] [Indexed: 02/19/2024] Open
Abstract
Ischaemic cardiovascular diseases, including peripheral and coronary artery disease, myocardial infarction, and stroke, remain major comorbidities for individuals with type 2 diabetes (T2D) and obesity. During cardiometabolic chronic disease (CMCD), hyperglycaemia and excess adiposity elevate oxidative stress and promote endothelial damage, alongside an imbalance in circulating pro-vascular progenitor cells that mediate vascular repair. Individuals with CMCD demonstrate pro-vascular 'regenerative cell exhaustion' (RCE) characterized by excess pro-inflammatory granulocyte precursor mobilization into the circulation, monocyte polarization towards pro-inflammatory vs. anti-inflammatory phenotype, and decreased pro-vascular progenitor cell content, impairing the capacity for vessel repair. Remarkably, targeted treatment with the sodium-glucose cotransporter-2 inhibitor (SGLT2i) empagliflozin in subjects with T2D and coronary artery disease, and gastric bypass surgery in subjects with severe obesity, has been shown to partially reverse these RCE phenotypes. SGLT2is and glucagon-like peptide-1 receptor agonists (GLP-1RAs) have reshaped the management of individuals with T2D and comorbid obesity. In addition to glucose-lowering action, both drug classes have been shown to induce weight loss and reduce mortality and adverse cardiovascular outcomes in landmark clinical trials. Furthermore, both drug families also act to reduce systemic oxidative stress through altered activity of overlapping oxidase and antioxidant pathways, providing a putative mechanism to augment circulating pro-vascular progenitor cell content. As SGLT2i and GLP-1RA combination therapies are emerging as a novel therapeutic opportunity for individuals with poorly controlled hyperglycaemia, potential additive effects in the reduction of oxidative stress may also enhance vascular repair and further reduce the ischaemic cardiovascular comorbidities associated with T2D and obesity.

Abstract
Dapagliflozin, a sodium-glucose co-transporter-2 inhibitor and semaglutide, a glucagon-like peptide 1 receptor agonist, have both demonstrated efficacy in glycemic control, reducing blood pressure, body weight, risk of renal and heart failure in type 2 diabetes mellitus. In this observational, real-world, study we aimed to investigate the efficacy of the combination therapy with those two agents over glycemic control. We thus obtained the data of 1335 patients with type 2 diabetes followed by 11 Diabetes centers in Lombardia, Italy. A group of 443 patients was treated with dapagliflozin alone, the other group of 892 patients was treated with the combination therapy of dapagliflozin plus oral semaglutide. We analyzed changes in glycated hemoglobin from baseline to 6 months of follow-up, as well as changes in fasting glycemia, body weight, body mass index, systolic and diastolic pressure, heart rate, creatinine, estimated glomerular filtration rate and albuminuria. Both groups of patients showed an improvement of glycometabolic control after 6 months of treatment; indeed, the treatment with dapagliflozin plus oral semaglutide showed a reduction of glycated hemoglobin of 1.2% as compared to the 0.5% reduction observed in the dapagliflozin alone group. Significant changes were observed in body mass index, fasting plasmatic glucose, blood pressure, total cholesterol, LDL and albumin to creatinine ratio, with a high rate (55%) of near-normalization of glycated hemoglobin. Our real world data confirmed the potential of the oral combination therapy dapagliflozin with semaglutide in inducing pharmacological remission of type 2 diabetes mellitus.

Abstract
Cardiovascular complications and renal disease is the growing cause of mortality in patients with diabetes. The subversive complications of diabetes such as hyperglycemia, hyperlipidemia and insulin resistance lead to an increase in the risk of myocardial infarction (MI), stroke, heart failure (HF) as well as chronic kidney disease (CKD). Among the commercially available anti-hyperglycemic agents, incretin-based medications appear to be safe and effective in the treatment of type 2 diabetes mellitus (T2DM) and associated cardiovascular and renal disease. Glucagon-like peptide 1 receptor agonists (GLP-1RAs) have been shown to be fruitful in reducing HbA1c, blood glucose, lipid profile, and body weight in diabetic patients. Several preclinical and clinical studies revealed the safety, efficacy, and preventive advantages of GLP-1RAs against diabetes- induced cardiovascular and kidney disease. Data from cardio-renal outcome trials had highlighted that GLP-1RAs protected people with established CKD from significant cardiovascular disease, lowered the likelihood of hospitalization for heart failure (HHF), and lowered all-cause mortality. They also had a positive effect on people with end-stage renal disease (ESRD) and CKD. Beside clinical outcomes, GLP-1RAs reduced oxidative stress, inflammation, fibrosis, and improved lipid profile pre-clinically in diabetic models of cardiomyopathy and nephropathy that demonstrated the cardio-protective and reno-protective effect of GLP-1RAs. In this review, we have focused on the recent clinical and preclinical outcomes of GLP-1RAs as cardio-protective and reno-protective agents as GLP-1RAs medications have been demonstrated to be more effective in treating T2DM and diabetes-induced cardiovascular and renal disease than currently available treatments in clinics, without inducing hypoglycemia or weight gain.

Abstract
AIM To validate pharmacodynamic responses to sodium-glucose co-transporter-2 (SGLT2) inhibitors and test for association with genetic variants in SLC5A4, SLC5A9, and SLC2A9. METHODS Canagliflozin (300 mg), a SGLT2 inhibitor, was administered to 30 healthy volunteers. Several endpoints were measured to assess clinically relevant responses, including drug-induced increases in urinary excretion of glucose, sodium and uric acid. RESULTS This pilot study confirmed that canagliflozin (300 mg) triggered acute changes in mean levels of several biomarkers: fasting plasma glucose (-4.1 mg/dL; P = 6 × 10-5 ), serum creatinine (+0.05 mg/dL; P = 8 × 10-4 ) and serum uric acid (-0.90 mg/dL; P = 5 × 10-10 ). The effects of sex on glucosuria depended upon how data were normalized. Whereas males' responses were ~60% greater when data were normalized to body surface area, males and females exhibited similar responses when glucosuria was expressed as grams of urinary glucose per gram-creatinine. The magnitude of glucosuria was not significantly correlated with fasting plasma glucose, estimated glomerular filtration rate or age in those healthy individuals without diabetes with an estimated glomerular filtration rate of more than 60 mL/min/1.73m2 . CONCLUSIONS Normalizing data relative to creatinine excretion will facilitate including data from males and females in a single analysis. Furthermore, because our ongoing pharmacogenomic study (NCT02891954) is conducted in healthy individuals, this will facilitate detection of genetic associations with limited confounding by other factors such as HbA1c and renal function.

Abstract
Obesity is a heterogeneous disease and there is wide patient-to-patient variability in response to all anti-obesity treatments including lifestyle modifications, anti-obesity medications (AOMs), devices, and bariatric surgery. To effectively treat obesity, practitioners must be knowledgeable about all of these treatment modalities including on-label and off-label AOMs. Care should be individualized to the patient taking into consideration their unique challenges with weight loss, their goals, the presence of comorbidities, medication contraindications, and drug-drug interactions. There is currently no way to know which AOM will be most effective for a patient without trial and error; therefore, prescribe AOMs in sequence and consider combination therapy for optimal results. This article reviews the efficacy, safety, prescribing information, and other considerations for all of the currently available AOMs.

Abstract
Sodium glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like-peptide-1 receptor (GLP-1-R) agonists are novel therapeutic agents used for the management of type 2 diabetes mellitus (T2DM). Recently, large-scale randomized clinical trials have been conducted to assess the cardiovascular safety of these medications. The findings of these trials have revealed that both SGLT2 inhibitors and GLP-1-R agonists exhibit favorable cardioprotective effects, including reduction in cardiovascular and all-cause mortality, a decreased risk of chronic kidney disease progression, a decrease in hospitalization for heart failure (HF), an effect shown by SGLT2 inhibitors, and stroke prevention, an effect shown by GLP-1-R agonists. Based on the results from above studies, the European and American Diabetes Associations have issued new recommendations strongly endorsing the use of SGLT2 inhibitors and GLP-1-R agonists in combination with metformin for patients with T2DM who have additional cardiovascular (CV) comorbidities or risk factors. The primary aim of this combined therapy is to prevent CV events. Although both medication groups offer beneficial effects, they demonstrate slightly different profiles. SGLT2 inhibitors have exhibited better effects regarding a reduced incidence of HF, whereas GLP-1-R agonists have shown a reduced risk of CV events, particularly stroke. Moreover, recent European Society of Cardiology as well as American College of Cardiology and American Heart Association guidelines of HF treatment stressed the importance of SGLT2 inhibitor administration in patients with HF regardless of T2DM. In this context, we present and discuss the outcomes of the most recent trials investigating the impact of SGLT2 inhibitors and GLP-1-R agonists on renal and cardiovascular outcomes in patients, both with and without T2DM. Additionally, we explore the synergistic effects of combining SGLT2 inhibitors and GLP-1-R agonists in patients with cardiovascular disease.

Abstract
Aim SGLT2 inhibitors provide multiple benefits to patients with type 2 diabetes - including improved glycemic control and decreased risks of cardiorenal disease. Because drug responses vary among individuals, we initiated investigations to identify genetic variants associated with the magnitude of drug responses. Methods Canagliflozin (300 mg) was administered to 30 healthy volunteers. Several endpoints were measured to assess clinically relevant responses - including drug-induced increases in urinary excretion of glucose, sodium, and uric acid. Results This pilot study confirmed that canagliflozin (300 mg) triggered acute changes in mean levels of several biomarkers: fasting plasma glucose (-4.1 mg/dL; p=6x10), serum creatinine (+0.05 mg/dL; p=8×10 -4 ), and serum uric acid (-0.90 mg/dL; p=5×10 -10 ). The effects of sex on glucosuria depended upon how data were normalized. Whereas males' responses were ∼60% greater when data were normalized to body surface area, males and females exhibited similar responses when glucosuria was expressed as grams of urinary glucose per gram-creatinine. The magnitude of glucosuria was not significantly correlated with fasting plasma glucose, estimated GFR, or age in these healthy non-diabetic individuals with estimated GFR>60 mL/min/1.73m 2 . Conclusions Normalizing data relative to creatinine excretion will facilitate including data from males and females in a single analysis. Furthermore, because our ongoing pharmacogenomic study ( NCT02891954 ) is conducted in healthy individuals, this will facilitate detection of genetic associations with limited confounding by other factors such as age and renal function.

Distinct Mechanisms Responsible for the Increase in Glucose Production and Ketone Formation Caused by Empagliflozin in T2DM Patients. Diabetes Care 2023; 46:978-984. [PMID: 36857415 PMCID: PMC10154659 DOI: 10.2337/dc22-0885] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 01/30/2023] [Indexed: 03/03/2023]
Abstract
OBJECTIVE To examine the mechanisms responsible for the increase in glucose and ketone production caused by empagliflozin in patients with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS Twelve subjects with T2DM participated in two studies performed in random order. In study 1, endogenous glucose production (EGP) was measured with 8-h infusion of 6,6,D2-glucose. Three hours after the start of 6,6,D2-glucose infusion, subjects ingested 25 mg empagliflozin (n = 8) or placebo (n = 4), and norepinephrine (NE) turnover was measured before and after empagliflozin ingestion with 3H-NE infusion. Study 2 was similar to study 1 but performed under pancreatic clamp conditions. RESULTS When empagliflozin was ingested under fasting conditions, EGP increased by 31% in association with a decrease in plasma glucose (-34 mg/dL) and insulin (-52%) concentrations and increases in plasma glucagon (+19%), free fatty acid (FFA) (+29%), and β-hydroxybutyrate (+48%) concentrations. When empagliflozin was ingested under pancreatic clamp conditions, plasma insulin and glucagon concentrations remained unchanged, and the increase in plasma FFA and ketone concentrations was completely blocked, while the increase in EGP persisted. Total-body NE turnover rate was greater in subjects receiving empagliflozin (+67%) compared with placebo under both fasting and pancreatic clamp conditions. No difference in plasma NE concentration was observed in either study. CONCLUSIONS The decrease in plasma insulin and increase in plasma glucagon concentration caused by empagliflozin is responsible for the increase in plasma FFA concentration and ketone production. The increase in EGP caused by empagliflozin is independent of the change in plasma insulin or glucagon concentrations and is likely explained by the increase in NE turnover.

Abstract
Obesity is a complex metabolic condition that can have a negative impact on one's health and even result in mortality. The management of obesity has been addressed in a number of ways, including lifestyle changes, medication using appetite suppressants and thermogenics, and bariatric surgery for individuals who are severely obese. Liraglutide and semaglutide are two of the five Food and Drug Administration (FDA)-approved anti-obesity drugs that are FDA-approved agents for the treatment of type 2 diabetes mellitus (T2DM) patients. In order to highlight the positive effects of these drugs as anti-obesity treatments, we analyzed the weight loss effects of T2DM agents that have demonstrated weight loss effects in this study by evaluating clinical studies that were published for each agent. Many clinical studies have revealed that some antihyperglycemic medications can help people lose weight, while others either cause weight gain or neutral results. Acarbose has mild weight loss effects and metformin and sodium-dependent glucose cotransporter proteins-2 (SGLT-2) inhibitors have modest weight loss effects; however, some glucagon-like peptide-1 (GLP-1) receptor agonists had the greatest impact on weight loss. Dipeptidyl peptidase 4 (DPP-4) inhibitors showed a neutral or mild weight loss effect. To sum up, some of the GLP-1 agonist drugs show promise as weight-loss treatments.

[PMID: 37005640 PMCID: PMC10067319 DOI: 10.1186/s12933-023-01798-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 03/12/2023] [Indexed: 04/04/2023] Open
Abstract
Due to their cardiovascular protective effect, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT2is) represent breakthrough therapies for type 2 diabetes mellitus (T2DM). In this review article, we discuss the mechanistic and clinical synergies that make the combined use of GLP-1RAs and SGLT2is appealing in patients with T2DM. Overall, the presented cumulative evidence supports the benefits of GLP-1RA plus SGLT2i combination therapy on metabolic-cardiovascular-renal disease in patients with T2DM, with a low hypoglycemia risk. Accordingly, we encourage the adoption of GLP-1RA plus SGLT2i combination therapy in patients with T2DM and established atherosclerotic cardiovascular disease (ASCVD) or multiple risk factors for ASCVD (i.e., age ≥ 55 years, overweight/obesity, dyslipidemia, hypertension, current tobacco use, left ventricular hypertrophy, and/or proteinuria). Regarding renal effects, the evidence of SGLT2is in preventing kidney failure is more abundant than for GLP-1RAs, which showed a beneficial effect on albuminuria but not on hard kidney endpoints. Hence, in case of persistent albuminuria and/or uncontrolled metabolic risks (i.e., inadequate glycemic control, hypertension, overweight/obesity) on SGLT2i therapy, GLP-1RAs should be considered as the preferential add-on therapy in T2DM patients with chronic kidney disease. Despite the potential clinical benefits of GLP-1RA plus SGLT2i combination therapy in patients with T2DM, several factors may delay this combination to become a common practice soon, such as reimbursement and costs associated with polypharmacy. Altogether, when administering GLP-1RA plus SGLT2i combination therapy, it is important to adopt an individualized approach to therapy taking into account individual preferences, costs and coverage, toxicity profile, consideration of kidney function and glucose-lowering efficacy, desire for weight loss, and comorbidities.

Abstract
Both GLP-1 receptor agonists (GLP-1RA) and SGLT-2 inhibitors (SGLT-2I) are newer classes of anti-diabetic agents that lower HbA1c moderately and decrease body weight and systolic blood pressure (SBP) modestly. Combination therapy with GLP-1RA plus SGLT-2I have shown a greater reduction in HbA1c, body weight, and SBP compared to either agent alone without any significant increase in hypoglycemia or other side effects. Since several agents from each class of these drugs have shown an improvement in cardiovascular (CV) and renal outcomes in their respective cardiovascular outcome trials (CVOT), combination therapy is theoretically expected to have additional CV and renal benefits. In this comprehensive opinion review, we found HbA1c lowering with GLP-1RA plus SGLT-2I to be less than additive compared to the sum of HbA1c lowering with either agent alone, although body weight lowering was nearly additive and the SBP lowering was more than additive. Our additional meta-analysis of CV outcomes with GLP-1RA plus SGLT-2I combination therapy from the pooled data of five CVOT found a similar reduction in three-point major adverse cardiovascular events compared to GLP-1RA or SGLT-2I alone, against placebo. Interestingly, a greater benefit in reduction of heart failure hospitalization with GLP-1RA plus SGLT-2I combination therapy was noted in the pooled meta-analysis of two randomized controlled trials. Future adequately powered trials can confirm whether additional CV or renal benefit is truly exerted by GLP-1RA plus SGLT-2I combination therapy.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have become agents of choice for people with type 2 diabetes (T2D) with established cardiovascular disease or in high-risk individuals. With currently available GLP-1 RAs, 51%-79% of subjects achieve an HbA1c target of less than 7.0% and 4%-27% lose 10% of body weight, illustrating the need for more potent agents. Three databases (PubMed, Cochrane, Web of Science) were searched using the MESH terms 'glucagon-like peptide-1 receptor agonist', 'glucagon receptor agonist', 'glucose-dependent insulinotropic peptide', 'dual or co-agonist', and 'tirzepatide'. Quality of papers was scored using PRISMA guidelines. Risk of bias was evaluated using the Cochrane assessment tool. An HbA1c target of less than 7.0% was attained by up to 80% with high-dose GLP-1 RAs and up to 97% with tirzepatide, with even up to 62% of people with T2D reaching an HbA1c of less than 5.7%. A body weight loss of 10% or greater was obtained by up to 50% and up to 69% with high-dose GLP-1 RAs or tirzepatide, respectively. The glucose- and weight-lowering effects of the GLP-1/glucagon RA cotadutide equal those of liraglutide 1.8 mg. Gastrointestinal side effects of high-dose GLP-1 RAs and co-agonists occurred in 30%-70% of patients, mostly arising within the first 2 weeks of the first dose, being mild or moderate in severity, and transient. The development of high-dose GLP-1 RAs and the dual GLP-1/glucose-dependent insulinotropic peptide RA tirzepatide resulted in increasing numbers of people reaching HbA1c and body weight targets, with up to 62% attaining normoglycaemia with 15-mg tirzepatide. Whether this will also translate to better cardiovascular outcomes and affect treatment guidelines remains to be studied.

Abstract
Background Evidence is limited in comparing treatment modification by substitution or add‐on of glucose‐lowering medications in patients with type 2 diabetes. This observational study aims to compare switching versus add‐on of incretin‐based drugs among patients with type 2 diabetes on background sodium‐glucose cotransporter‐2 inhibitors (SGLT2i). Methods and Results This population‐based, retrospective cohort study was conducted using the IQVIA Medical Research Data, including adults with type 2 diabetes on background SGLT2i from 2005 to 2020. New users of incretin‐based drugs were allocated into the “Switch” group if they had discontinued SGLT2i treatment, or the “Add‐on” group if their background SGLT2i was continued. Baseline characteristics of patients were balanced between groups. Study outcomes were all‐cause mortality, cardiovascular diseases, kidney diseases, hypoglycemia, and ketoacidosis. Patients were observed from the index date of initiating incretin‐based drugs until the earliest of an outcome event, death, or data cut‐off date. Changes in anthropometric and metabolic parameters were also compared between groups from baseline to 12‐month follow‐up. A total of 2888 patients were included, classified into “Switch” (n=1461) or “Add‐on” group (n=1427). Median follow‐up was 18 months with 5183 person‐years. Overall, no significant differences in the risks of study outcomes were observed between groups; however, patients in the “Add‐on” group achieved significantly greater reductions in glycated hemoglobin, weight, percentage weight loss, and systolic blood pressure than their “Switch” counterparts. Conclusions Initiating incretin‐based drugs as add‐on among patients with type 2 diabetes on background SGLT2i was associated with risks of clinical end points comparable to switching treatments, in addition to better glycemic and weight control observed with the combination approach.

Dapagliflozin plus exenatide on patients with type 2 diabetes awaiting bariatric surgery in the DEXBASU study. Sci Rep 2022; 12:3236. [PMID: 35217772 PMCID: PMC8881618 DOI: 10.1038/s41598-022-07250-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Accepted: 01/25/2022] [Indexed: 11/09/2022] Open
Abstract
The glucagon-like peptide-1 receptor agonist family together with the renal sodium/glucose cotransporter-2 inhibitors have garnered interest as potential therapeutic agents for subjects with type 2 diabetes and obesity. In these patients, bariatric surgery is indicated based in a BMI ≥ 35 kg/m2. A 24-week non-blinded, randomized pilot study to assess the efficacy of subcutaneous exenatide 2.0 mg once weekly plus oral dapagliflozin 10 mg once daily (Group A) compared to a control group (Group B) in 56 patients with type 2 diabetes awaiting bariatric surgery was conducted (EudraCTid.: 2017-001,454-33). Both groups received an energy-deficit low-fat diet. The primary endpoint was the proportion of patients running off the criteria for bariatric surgery at the end of the follow-up period (BMI ≤ 35.0 kg/m2 or a BMI ≤ 40.0 kg/m2 plus an HbA1c ≤ 6.0%). Changes in the BMI were also of interest. The proportion of patients who ran off the criteria for bariatric surgery was larger in Group A than in the control group (45.8% vs. 12.0%, p = 0.010). Participants in Group A exhibited an absolute decrease in body weight and BMI of 8.1 kg (95%IC: − 11.0 to − 5.2) and 3.3 kg/m2 (95%IC: − 4.5 to − 2.2), respectively (p < 0.001 for both in comparison with Group B). A higher percentage of participants in Group A reached a BMI < 35 kg/m2 (45.8 vs 12.0%) and lost > 10% of their initial body weight (20.8 vs 0%) compared to Group B. The combination of exenatide plus dapagliflozin appears as a strategic option to reduce the waiting list for bariatric surgery, especially in those patients with type 2 diabetes.

Abstract
Aims: Glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter-2 inhibitors play a key role in the treatment of type 2 diabetes mellitus. This meta-analysis aims to evaluate the efficacy and safety of their combination, emphatically focusing on the effects of treatment duration and add-on drugs. Methods: Seven databases were searched until June 2021 for randomized controlled trials with a duration of at least 12 weeks, evaluating the effects of combination therapy with glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter-2 inhibitors. Results: A total of eight eligible articles were included, pooling data retrieved from 1895 patients with type 2 diabetes mellitus. Compared to monotherapy, combination therapy resulted in a greater reduction in glycated haemoglobin (HbA1c), body weight, fasting plasma glucose (FPG), 2 h postprandial glucose (2 h PG), systolic blood pressure (SBP), body mass index (BMI) and low-density lipoprotein cholesterol (LDL-C). The decrease in HbA1c, body weight and FPG was maintained for more than 1 year, but these effects gradually regressed over time. The risk for hypoglycaemia was significantly increased with combination therapy. In addition, drug discontinuation, diarrhoea, injection-site-related events, nausea, vomiting and genital infections were more likely to occur in combination therapy. Conclusion: Glucagon-like peptide-1 receptor agonist and sodium-glucose co-transporter-2 inhibitor combination therapy showed superior effects on reducing HbA1c, body weight, FPG, 2 h PG, SBP, BMI and LDL-C, without major safety issues, when compared with monotherapy in patients with type 2 diabetes mellitus.

Abstract
Obesity is one of the risk factors for the development and progression of chronic kidney disease (CKD). Several studies have shown the association between increased body mass index and kidney function decline. Obesity leads to CKD directly by acting as an independent risk factor and indirectly through increasing risks for diabetes, hypertension, and atherosclerosis, a group of well-established independent risk factors for CKD. Alterations in renal hemodynamics, inflammation, and in hormones and growth factors results in hyperfiltration injury and focal segmental glomerulosclerosis. In recent years, many studies have shown that the gut microbiome may play a role in the pathogenesis of obesity. Dysbiosis has been noted in obese subjects in both human and animal studies. Changes in the gut microbiome in obese patients promote weight gain by effectively extracting energy from diet, and induction of low-grade inflammation. Evidence also points to the role of inflammation within the adipose tissue in obesity as a key factor in the pathogenesis of obesity-related complications. Thus, obesity is the net result of complex interactions between behavioral, genetic, and environmental factors. In terms of management, conservative approaches are often the first option, but they often are unsuccessful in achieving and/or maintaining weight loss, particularly in severe obesity. Consequently, nonmedical management with bariatric surgery is the most effective treatment option for morbid obesity and has shown mitigation of multiple risk factors for the progression of CKD. The most frequently performed interventions are vertical sleeve gastrectomy and Roux-en-Y gastric bypass. Studies have shown that bariatric surgery is associated with beneficial effects on CKD by mitigating its risk factors by weight loss, reducing insulin resistance, hemoglobin A1c, and proteinuria, in addition to positive long-term outcomes. Because of the epidemic of obesity, the prevalence of obesity in kidney transplant recipients also is increasing. The maximal body mass index (BMI) threshold for kidney transplantation is not clear. The Organ Procurement Transplant Network/Scientific Registry of Transplant Recipients 2019 annual data report showed that the proportion of kidney transplant recipient candidates with a BMI of 30 kg/m2 or greater is increasing steadily. Morbid obesity is linked to adverse graft outcomes including delayed graft function, primary nonfunction, and decreased graft survival. Obesity is also an independent risk factor for cardiovascular death in kidney transplant recipients, suggesting that these patients should not be excluded from transplantation based on their BMI because transplantation is associated with lower mortality compared with dialysis. However, many centers exclude obese patients (with different BMI cut-off values) from transplantation to avoid postoperative complications. To minimize the surgical complications of kidney transplantation in obese patients, our center has adopted the robot-assisted kidney transplantation procedure. Our data show that this approach is comparable with historical nonobese controls in the United Network for Organ Sharing database in terms of patient and graft survival. Another surgical option for this group of patients at our center is a combined robotic sleeve gastrectomy and robotic-assisted kidney transplant. In a recent study, this approach showed promising results in terms of weight loss, patient survival, and graft survival, and might become more common in the future.

Combined exenatide and dapagliflozin has no additive effects on reduction of hepatocellular lipids despite better glycaemic control in patients with type 2 diabetes mellitus treated with metformin: EXENDA, a 24-week, prospective, randomized, placebo-controlled pilot trial. Diabetes Obes Metab 2021; 23:1129-1139. [PMID: 33464703 PMCID: PMC8247845 DOI: 10.1111/dom.14319] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 01/07/2021] [Accepted: 01/14/2021] [Indexed: 12/11/2022]
Abstract
AIMS To investigate the potential synergistic effects of combined exenatide (EXE) and dapagliflozin (DAPA) versus (PLAC) placebo and DAPA on hepatocellular lipid (HCL) reduction after 24 weeks of treatment. MATERIALS AND METHODS Thirty patients with type 2 diabetes were randomized to weekly EXE and daily DAPA (n = 16) or weekly PLAC and daily DAPA (n = 14). Inclusion criteria were glycated haemoglobin (HbA1c) 48 to 97 mmol/mol (6.5-11%), age 18 to 75 years, body mass index (BMI) ≥25 kg/m2 and metformin ≥1000 mg. The primary endpoint, HCL levels, were measured at baseline and after 24 weeks of treatment using magnetic resonance spectroscopy. Between-group effects were analysed using general linear models, adjusted for baseline outcome variables, age, sex and BMI. Within-group differences were assessed using a paired t-test. RESULTS After 24 weeks, HCLs were reduced in both treatment groups (absolute change from baseline: EXE + DAPA -4.4%, 95% confidence interval [CI] -8.2, -0.7, P < 0.05; PLAC + DAPA -3.9%, 95% CI -6.0, -1.7, P < 0.01; relative change: EXE + DAPA -35.6%, PLAC + DAPA -32.3%) with no difference between groups. Similar findings were observed for subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT). HbA1c (EXE + DAPA -17.8 mmol/mol, [95% CI -24.8, -10.8], P <0.001; PLAC + DAPA -6.9 mmol/mol, [95% CI -10.5, -3.3], P = 0.001) and fasting glucose significantly decreased in both groups, although EXE + DAPA achieved better glycaemic control than PLAC + DAPA (adjusted difference: HbA1c -6.0 mmol/mol [95% CI -9.7, -2.2], P < 0.01). Body weight was reduced in both treatment groups (EXE + DAPA -7.3 kg, 95% CI -9.9, -4.8, P <0.001; PLAC + DAPA -4.6 kg, 95% CI -7.4, -1.8, P <0.01) with comparable results between groups. Changes in HCLs and weight, hip and waist circumference, VAT and SAT were positively associated. CONCLUSION After 24 weeks, HCLs were significantly but comparably reduced in the EXE + DAPA and PLAC + DAPA groups, despite significantly better glycaemic control in the combined group EXE + DAPA. Changes in HCLs were associated with weight loss and reduction of visceral adiposity, but not with glucose control. Further studies are necessary to evaluate possible additional long-term effects of a combined treatment.

[PMID: 33068776 PMCID: PMC8085572 DOI: 10.1016/j.molmet.2020.101102] [Citation(s) in RCA: 546] [Impact Index Per Article: 182.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 10/09/2020] [Accepted: 10/12/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND GLP-1 receptor agonists (GLP-1 RAs) with exenatide b.i.d. first approved to treat type 2 diabetes in 2005 have been further developed to yield effective compounds/preparations that have overcome the original problem of rapid elimination (short half-life), initially necessitating short intervals between injections (twice daily for exenatide b.i.d.). SCOPE OF REVIEW To summarize current knowledge about GLP-1 receptor agonist. MAJOR CONCLUSIONS At present, GLP-1 RAs are injected twice daily (exenatide b.i.d.), once daily (lixisenatide and liraglutide), or once weekly (exenatide once weekly, dulaglutide, albiglutide, and semaglutide). A daily oral preparation of semaglutide, which has demonstrated clinical effectiveness close to the once-weekly subcutaneous preparation, was recently approved. All GLP-1 RAs share common mechanisms of action: augmentation of hyperglycemia-induced insulin secretion, suppression of glucagon secretion at hyper- or euglycemia, deceleration of gastric emptying preventing large post-meal glycemic increments, and a reduction in calorie intake and body weight. Short-acting agents (exenatide b.i.d., lixisenatide) have reduced effectiveness on overnight and fasting plasma glucose, but maintain their effect on gastric emptying during long-term treatment. Long-acting GLP-1 RAs (liraglutide, once-weekly exenatide, dulaglutide, albiglutide, and semaglutide) have more profound effects on overnight and fasting plasma glucose and HbA1c, both on a background of oral glucose-lowering agents and in combination with basal insulin. Effects on gastric emptying decrease over time (tachyphylaxis). Given a similar, if not superior, effectiveness for HbA1c reduction with additional weight reduction and no intrinsic risk of hypoglycemic episodes, GLP-1RAs are recommended as the preferred first injectable glucose-lowering therapy for type 2 diabetes, even before insulin treatment. However, GLP-1 RAs can be combined with (basal) insulin in either free- or fixed-dose preparations. More recently developed agents, in particular semaglutide, are characterized by greater efficacy with respect to lowering plasma glucose as well as body weight. Since 2016, several cardiovascular (CV) outcome studies have shown that GLP-1 RAs can effectively prevent CV events such as acute myocardial infarction or stroke and associated mortality. Therefore, guidelines particularly recommend treatment with GLP-1 RAs in patients with pre-existing atherosclerotic vascular disease (for example, previous CV events). The evidence of similar effects in lower-risk subjects is not quite as strong. Since sodium/glucose cotransporter-2 (SGLT-2) inhibitor treatment reduces CV events as well (with the effect mainly driven by a reduction in heart failure complications), the individual risk of ischemic or heart failure complications should guide the choice of treatment. GLP-1 RAs may also help prevent renal complications of type 2 diabetes. Other active research areas in the field of GLP-1 RAs are the definition of subgroups within the type 2 diabetes population who particularly benefit from treatment with GLP-1 RAs. These include pharmacogenomic approaches and the characterization of non-responders. Novel indications for GLP-1 RAs outside type 2 diabetes, such as type 1 diabetes, neurodegenerative diseases, and psoriasis, are being explored. Thus, within 15 years of their initial introduction, GLP-1 RAs have become a well-established class of glucose-lowering agents that has the potential for further development and growing impact for treating type 2 diabetes and potentially other diseases.

Abstract
Sodium-glucose co-transporter 2 (SGLT2) inhibitors facilitate urine glucose excretion by reducing glucose reabsorption, leading to ameliorate glycemic control. While the main characteristics of type 2 diabetes mellitus are insufficient insulin secretion and insulin resistance, SGLT2 inhibitors have some favorable effects on pancreatic β-cell function and insulin sensitivity. SGLT2 inhibitors ameliorate fatty liver and reduce visceral fat mass. Furthermore, it has been noted that SGLT2 inhibitors have cardio-protective and renal protective effects in addition to their glucose-lowering effect. In addition, several kinds of SGLT2 inhibitors are used in patients with type 1 diabetes mellitus as an adjuvant therapy to insulin. Taken together, SGLT2 inhibitors have amazing multifaceted effects that are far beyond prediction like some emerging magical medicine. Thereby, SGLT2 inhibitors are very promising as relatively new anti-diabetic drugs and are being paid attention in various aspects. It is noted, however, that SGLT2 inhibitors have several side effects such as urinary tract infection or genital infection. In addition, we should bear in mind the possibility of diabetic ketoacidosis, especially when we use SGLT2 inhibitors in patients with poor insulin secretory capacity.

Abstract
AIM To assess the associations between baseline glucose-lowering agents (GLAs) and cardiorenal outcomes with dapagliflozin versus placebo in the DECLARE-TIMI 58 study. MATERIALS AND METHODS DECLARE-TIMI 58 assessed the cardiorenal outcomes of dapagliflozin versus placebo in patients with type 2 diabetes. This post hoc analysis elaborates the efficacy and safety outcomes by baseline GLA for treatment effect and GLA-based treatment interaction. RESULTS At baseline, 14 068 patients (82.0%) used metformin, 7322 (42.7%) sulphonylureas, 2888 (16.8%) dipeptidyl peptidase-4 inhibitors, 750 (4.4%) glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and 7013 (40.9%) insulin. Dapagliflozin reduced the composite of cardiovascular death (CVD) and hospitalization for heart failure (HHF) versus placebo regardless of baseline GLA, with greater benefit in the small group of patients with baseline use of GLP-1 RAs (HR [95% CI] 0.37 [0.18, 0.78] vs. 0.86 [0.75, 0.98] in GLP-1 RA users vs. non-users, Pinteraction = .03). The overall HR for major adverse cardiovascular events (CVD, myocardial infarction or ischaemic stroke) was 0.93 (95% CI 0.84, 1.03) with dapagliflozin versus placebo, with no interaction by baseline GLA (Pinteraction > .05). The renal-specific outcome was reduced with dapagliflozin versus placebo in the overall cohort (HR [95%CI] 0.53[0.43-0.66]), with no interaction by baseline GLA (Pinteraction > .05). All of these outcomes were similar in those with versus those without baseline metformin use. CONCLUSIONS The effects of dapagliflozin on cardiorenal outcomes were generally consistent regardless of baseline GLA, with consistent benefits regardless of baseline metformin use. The potential clinical benefit of combining sodium-glucose co-transporter-2 inhibitors with GLP-1 RAs, given some evidence of cardiovascular risk reduction with both classes, should be explored further.

Glucagon-like-1 receptor agonists and sodium/glucose cotransporter-2 inhibitors combination—are we exploiting their full potential in a real life setting? World J Diabetes 2020; 11:540-552. [PMID: 33269065 PMCID: PMC7672794 DOI: 10.4239/wjd.v11.i11.540] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 09/29/2020] [Accepted: 10/19/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The sodium/glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like-1 receptor agonists (GLP-1RA) are antidiabetic agents effective both in hemoglobin A1c (HbA1c) reduction (with a low risk of hypoglycemia) and cardiovascular event prevention. In patients with type 2 diabetes, the add-on value of combination therapy of GLP-1RA and an SGLT-2i seems promising.
AIM To investigate whether the efficacy of GLP-1RA and SGLT-2i combination observed in randomized controlled trials translates into therapeutic benefits in the Croatian population during routine clinical practice and follow-up.
METHODS We included 200 type 2 diabetes patients with poor glycemic control and analyzed the effects of treatment intensification with (1) GLP-1RA on top of SGLT-2i, (2) SGLT-2i on top of GLP-1RA compared to (3) simultaneous addition of both agents. The primary study endpoint was the proportion of participants with HbA1c < 7.0% and/or 5% bodyweight reduction. Secondary outcomes included changes in fasting plasma glucose (FPG), prandial plasma glucose, low-density lipoprotein cholesterol, estimated glomerular filtration rate (eGFR), and cardiovascular (CV) incidents assessment over a follow-up period of 12 mo.
RESULTS The majority of patients were over 65-years-old, had diabetes duration for more than 10 years. The initial body mass index was 39.41 ± 5.49 kg/m2 and HbA1c 8.32 ± 1.26%. Around half of the patients in all three groups achieved target HbA1c below 7%. A more pronounced decrease in the HbA1c seen with simultaneous SGLT-2i and GLP-1RA therapy was a result of higher baseline HbA1c and not the effect of initiating combination therapy. The number of patients achieving FPG below 7.0 mmol/L was significantly higher in the SGLT-2i group (P = 0.021), and 5% weight loss was dominantly achieved in the simultaneous therapy group (P = 0.044). A composite outcome (reduction of HbA1c below 7% (53 mmol/mol) with 5% weight loss) was achieved in 32.3% of total patients included in the study. Only 18.2% of patients attained composite outcome defined as HbA1c below 7% (53 mmol/mol) with 5% weight loss and low-density lipoprotein cholesterol < 2.5 mmol/L. There were no significant differences between treatment groups. No differences were observed regarding CV incidents or eGFR according to treatment group over a follow-up period.
CONCLUSION Combination therapy with GLP-1RA and SGLT-2i is effective in terms of metabolic control, although it remains to be determined whether simultaneous or sequential intensification is better.

Abstract
AIM To assess the efficacy and safety of combination therapy with a glucagon-like peptide-1 receptor agonist (GLP-1 RA) and a sodium-glucose co-transporter-2 inhibitor (SGLT2i) in patients with type 2 diabetes. METHODS We searched Medline, Embase, the Cochrane Library and grey literature sources up to 2 December 2019 for randomized controlled trials in adults with type 2 diabetes assessing the combination of GLP-1RA and SGLT2i, either as co-initiation therapy or as add-on to each other, against placebo or an active comparator. The primary outcome was change in HbA1c . Secondary outcomes included change in body weight, blood pressure and estimated glomerular filtration rate, and incidence of severe hypoglycaemia, all-cause mortality, cardiovascular mortality, myocardial infarction, stroke and hospitalization for heart failure. We pooled data using random effects meta-analyses. RESULTS Seven trials (1913 patients) were eligible. Compared with GLP-1RA, GLP-1RA/SGLT2i combination therapy was associated with a greater reduction in HbA1c (weighted mean difference -0.61%, 95% CI -1.09% to -0.14%, four studies), body weight (-2.59 kg, -3.68 to -1.51 kg, three studies) and systolic blood pressure (-4.13 mmHg, -7.28 to -0.99 mmHg, four studies). Compared with SGLT2i, GLP-1RA/SGLT2i combination therapy reduced HbA1c (-0.85%, -1.19% to -0.52%, six studies) and systolic blood pressure (-2.66 mmHg, -5.26 to -0.06 mmHg, six studies), but not body weight (-1.46 kg, -2.94 to 0.03 kg, five studies). After excluding data for one trial that had a considerably longer duration than the remaining studies, body weight was also reduced versus SGLT2i (-1.79 kg, -2.99 to -0.59 kg, five studies). Combination therapy did not increase the incidence of severe hypoglycaemia. Data for mortality and cardiovascular outcomes were scarce. CONCLUSIONS GLP-1RA/SGLT2i combination therapy seems to reduce HbA1c , body weight and systolic blood pressure without increasing the risk of severe hypoglycaemia compared with either GLP-1RA or SGLT2i. No conclusions can be made regarding long-term effectiveness or the effect on cardiovascular outcomes.

AIM To examine the effect of combination therapy with canagliflozin plus liraglutide versus each agent alone on beta cell function in type 2 diabetes mellitus (T2DM) patients. RESEARCH DESIGN AND METHODS A total of 45 poorly controlled (HbA1c = 7%-11%) T2DM patients received an oral glucose tolerance test (OGTT) before and after 16 weeks of treatment with: (i) liraglutide (LIRA); (ii) canagliflozin (CANA); (iii) liraglutide plus canagliflozin (CANA/LIRA). RESULTS Both liraglutide and canagliflozin significantly lowered HbA1c with no significant additive effect of the combination on HbA1c (0.89%, 1.43%, and 1.67% respectively). Insulin secretion during the OGTT, measured with (∆C-Pep/∆G)0-120, increased in the 3 groups (from 0.30 ± 0.06 to 0.48 ± 0.10; 0.29 ± 0.05 to 0.98 ± 0.23; and 0.24 ± 0.06 to 1.09 ± 0.12 in subjects receiving CANA, LIRA and CANA/LIRA respectively; P = 0.02 for CANA vs LIRA, P < 0.0001, CANA/LIRA vs CANA), and the increase in insulin secretion was associated with an increase in beta cell glucose sensitivity (29 ± 5 to 55 ± 11; 33 ± 6 to 101 ± 16; and 28 ± 6 to 112 ± 12, respectively; P = 0.01 for CANA vs LIRA, P < 0.0001, CANA/LIRA vs CANA). No significant difference in the increase in insulin secretion or beta cell glucose sensitivity was observed between subjects in LIRA or CANA/LIRA groups. The decrease in HbA1c strongly and inversely correlated with the increase in beta cell glucose sensitivity (r = 0.71, P < 0.001). In multivariate regression model, improved beta cell glucose sensitivity was the strongest predictor of HbA1c decrease with each therapy. CONCLUSION Improved beta cell glucose sensitivity with canagliflozin monotherapy and liraglutide monotherapy or in combination is major factor responsible for the HbA1c decrease. Canagliflozin failed to produce an additive effect to improve beta cell glucose sensitivity above that observed with liraglutide.

Practical Considerations and Rationale for Glucagon-Like Peptide-1 Receptor Agonist Plus Sodium-Dependent Glucose Cotransporter-2 Inhibitor Combination Therapy in Type 2 Diabetes. Can J Diabetes 2020; 45:291-302. [PMID: 33189580 DOI: 10.1016/j.jcjd.2020.09.005] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 08/31/2020] [Accepted: 09/07/2020] [Indexed: 02/07/2023]
Abstract
Glucagon-like peptide-1 receptor agonists and sodium-dependent glucose cotransporter-2 inhibitors have demonstrated clinically significant benefits on glycated hemoglobin, weight, blood pressure and cardiorenal outcomes. The emerging evidence from clinical trials and meta-analyses that assessed the combination of these 2 classes of drugs has been promising. An expert forum that included individuals with expertise in endocrine, cardiology and nephrology issues was held in May 2020 to review the literature on the metabolic and cardiorenal benefits of these 2 classes, independently and in combination, in adults with type 2 diabetes mellitus. Although hard outcome data are not available, the group concluded that the combination of glucagon-like peptide-1 receptor agonists with sodium-dependent glucose cotransporter-2 inhibitors is an emerging option for managing adults with type 2 diabetes as long as cost is not a barrier. Ongoing research may offer further insights on hard cardiorenal outcomes for this therapeutic combination as well as provide direction on the potential of this approach in obesity, nonalcoholic fatty liver disease, nonalcoholic steatohepatitis and populations without diabetes.

Evidence Against an Important Role of Plasma Insulin and Glucagon Concentrations in the Increase in EGP Caused by SGLT2 Inhibitors. Diabetes 2020; 69:681-688. [PMID: 31915153 PMCID: PMC7085246 DOI: 10.2337/db19-0770] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Accepted: 01/01/2020] [Indexed: 12/20/2022]
Abstract
Sodium-glucose cotransport 2 inhibitors (SGLT2i) lower plasma glucose but stimulate endogenous glucose production (EGP). The current study examined the effect of dapagliflozin on EGP while clamping plasma glucose, insulin, and glucagon concentrations at their fasting level. Thirty-eight patients with type 2 diabetes received an 8-h measurement of EGP ([3-3H]-glucose) on three occasions. After a 3-h tracer equilibration, subjects received 1) dapagliflozin 10 mg (n = 26) or placebo (n = 12); 2) repeat EGP measurement with the plasma glucose concentration clamped at the fasting level; and 3) repeat EGP measurement with inhibition of insulin and glucagon secretion with somatostatin infusion and replacement of basal plasma insulin and glucagon concentrations. In study 1, the change in EGP (baseline to last hour of EGP measurement) in subjects receiving dapagliflozin was 22% greater (+0.66 ± 0.11 mg/kg/min, P < 0.05) than in subjects receiving placebo, and it was associated with a significant increase in plasma glucagon and a decrease in the plasma insulin concentration compared with placebo. Under glucose clamp conditions (study 2), the change in plasma insulin and glucagon concentrations was comparable in subjects receiving dapagliflozin and placebo, yet the difference in EGP between dapagliflozin and placebo persisted (+0.71 ± 0.13 mg/kg/min, P < 0.01). Under pancreatic clamp conditions (study 3), dapagliflozin produced an initial large decrease in EGP (8% below placebo), followed by a progressive increase in EGP that was 10.6% greater than placebo during the last hour. Collectively, these results indicate that 1) the changes in plasma insulin and glucagon concentration after SGLT2i administration are secondary to the decrease in plasma glucose concentration, and 2) the dapagliflozin-induced increase in EGP cannot be explained by the increase in plasma glucagon or decrease in plasma insulin or glucose concentrations.
