[Application of new glucose lowering drugs: DPP-4 inhibitors, GLP-1 receptor agonists and SGLT-2 inhibitors].
Verburg, AFE, van den Donk, M, Wiersma, T
Nederlands tijdschrift voor geneeskunde. 2019
Abstract
A comprehensive review of the literature on DPP-4 inhibitors, GLP-1 receptor agonists and SGLT-2 inhibitors has resulted in small changes to the medication roadmap of the type 2 diabetes mellitus standard of the Dutch College of General Practitioners. SGLT-2 inhibitors and GLP-1 receptor agonists may have benefits related to cardiovascular outcomes in patients with high cardiovascular risk, especially in those who have experienced a cardiovascular event. However, ascribing effectiveness related to cardiovascular outcomes on the basis of a single cardiovascular safety trial is premature. Metformin, sulfonylurea derivatives and insulin are still the cornerstone of type 2 diabetes mellitus treatment in primary care.

Abstract
The prevalence of type 2 diabetes mellitus (T2DM), which is associated with cardiovascular morbidity and mortality, is increasing worldwide. Although there have been advances in diabetes treatments that reduce microvascular complications (nephropathy, neuropathy, retinopathy), many clinical studies have found that conventional oral hypoglycemic agents and glucose control alone failed to reduce cardiovascular disease. Thus, incretin-based therapies including glucagon-like peptide 1 (GLP-1) receptor agonists (RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT-2Is) represent a new area of research, and may serve as novel therapeutics for treating hyperglycemia and modifying other cardiovascular risk factors. Recently, it has been confirmed that several drugs in these classes, including canagliflozin, empagliflozin, semaglutide, and liraglutide, are safe and possess cardioprotective effects. We review the most recent cardiovascular outcome trials on GLP-1RAs and SGLT-2Is, and discuss their implications for treating patients with T2DM in terms of protective effects against cardiovascular disease.

Abstract
OBJECTIVE Sodium-glucose co-transporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) are now considered as key players in the treatment of type 2 diabetes mellitus (T2DM). The purpose of this meta-analysis was to provide precise effect estimates regarding the safety and efficacy of the addition of a GLP-1RA on top of SGLT-2i treatment. RESEARCH DESIGN AND METHODS PubMed and CENTRAL, along with grey literature sources, were searched from their inception to May 2019 for randomized controlled trials (RCTs) with a duration ≥ 12 weeks, evaluating the safety and efficacy of addition of a GLP-1RA on a SGLT-2i compared to SGLT-2i alone in patients with T2DM. We also used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the credibility of our summary estimates. RESULTS We identified three eligible RCTs, pooling data retrieved from 1,042 patients with T2DM in total. Administration of the maximum dose of a GLP-1RA on top of SGLT-2i treatment compared to SGLT-2i alone resulted in significant decrease in HbA1c by 0.91% (95% CI; -1.41 to -0.42) [GRADE moderate], in body weight by 1.95 kg (95% CI; -3.83 to -0.07) [GRADE moderate], in fasting plasma glucose by 1.53 mmol/L (95% CI; -2.17 to -0.88) [GRADE moderate] and in systolic blood pressure levels by 3.64 mm Hg (95% CI -6.24 to -1.03). No significant effects on lipid profile and diastolic blood pressure were demonstrated. A significant increase in the risk for any hypoglycemia (RR: 2.62, 95% CI; 1.15-5.96, I2 = 33%) [GRADE moderate] and for nausea (RR: 3.21, 95% CI; 1.36-7.54, I2 = 63%) [GRADE moderate] and a non-significant increase in the risk for diarrhoea (RR: 1.64, 95% CI; 0.98-2.75, I2 = 0%) [GRADE low] were documented. No other safety issues were identified. CONCLUSIONS This meta-analysis suggests that a GLP-1RA/SGLT-2i combination, if tolerated, exerts significant beneficial effects on glycemic control and body weight loss, however increasing the risk for any hypoglycemia and gastrointestinal adverse events.

Profile of semaglutide in the management of type 2 diabetes: design, development, and place in therapy.
Gomez-Peralta, F, Abreu, C
Drug design, development and therapy. 2019;:731-738
Abstract
Type 2 diabetes mellitus (T2DM) has become one of the leading causes of morbidity and mortality in developed countries. Low efficacy, weight gain, and hypoglycemia are the main pitfalls of previous treatments for T2DM. New therapies have been designed with the aim of improving the results in efficacy and quality of life. Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1 RA) increase glucose-dependent insulin secretion, decrease gastric emptying, and reduce postprandial glucagon secretion. The last GLP-1 RA approved by the US Food and Drug Administration and European Medicines Agency was semaglutide. This review describes its pharmacology, core clinical data coming from the randomized controlled trials included in the development program, proven cardiovascular benefits, safety issues, and precautions for the use of semaglutide in special populations. Additionally, an overview of the positioning of semaglutide in T2DM therapy and practical issues regarding semaglutide initiation are offered.

Abstract
In individuals with type 2 diabetes, glycaemic control and cardiovascular risk factor management reduces the likelihood of late-stage diabetic complications. Guidelines recommend treatment goals targeting HbA1c, body weight, blood pressure, and low-density lipoprotein cholesterol. Development of new treatments for type 2 diabetes requires an understanding of their mechanism and efficacy, as well as their relative effects compared to other treatment choices, plus demonstration of cardiovascular safety. Subcutaneous semaglutide is a glucagon-like peptide-1 receptor agonist currently approved in several countries for once-weekly treatment of type 2 diabetes. Semaglutide works via the incretin pathway, stimulating insulin and inhibiting glucagon secretion from the pancreatic islets, leading to lower blood glucose levels. Semaglutide also decreases energy intake by reducing appetite and food cravings, and lowering relative preference for fatty, energy-dense foods. Semaglutide was evaluated in the SUSTAIN clinical trial programme in over 8000 patients across the spectrum of type 2 diabetes. This review details the efficacy and safety profile of semaglutide in the SUSTAIN 1-5 and 7 trials, and its cardiovascular safety profile in the SUSTAIN 6 trial. Semaglutide consistently demonstrated superior and sustained glycemic control and weight loss vs. all comparators evaluated. In SUSTAIN 6, involving patients at high risk of cardiovascular disease, semaglutide significantly decreased the occurrence of cardiovascular events compared with placebo/standard of care (hazard ratio 0.74, P < 0.001 for non-inferiority). Through a comprehensive phase 3 clinical trial program, we have a detailed understanding of semaglutide's efficacy, safety, cardiovascular effects and comparative role in the treatment of type 2 diabetes.

Abstract
We conducted a systematic review and meta-analysis of randomized controlled trials to assess the effect of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) on microvascular endpoints in adult patients with type 2 diabetes. We included 60 studies with 60 077 patients. GLP-1 RAs marginally reduced urinary albumin-to-creatinine ratio compared with placebo or other antidiabetic agents (weighted mean difference - 2.55 mg/g; 95% confidence interval [CI] -4.37 to -0.73 and -5.52; -10.89 to -0.16, respectively) and had no clinically relevant effect on change in estimated glomerular filtration rate. Treatment with GLP-1 RAs did not increase incidence of diabetic retinopathy, macular oedema, retinal detachment and retinal haemorrhage, irrespective of comparator. Nevertheless, incidence of vitreous haemorrhage was higher in subjects treated with GLP-1 RAs compared with placebo (odds ratios 1.93; 95% CI 1.09 to 3.42). In conclusion, GLP-1 RAs are safe regarding nephropathy- and retinopathy-related outcomes. Caution may be warranted for incidence of vitreous haemorrhage. The low overall quality of evidence highlights the need for consistent assessment and reporting of microvascular endpoints in future trials.

Current cardiology reports. 2019;(9):100
Abstract
PURPOSE OF REVIEW This review will serve to highlight the clinical rationale used in the selection of sodium-glucose cotransporter 2 inhibitors (SGLT2-i) or glucagon-like peptide 1 receptor agonists (GLP1-ra). RECENT FINDINGS SGLT2-i and GLP1-ra are the first anti-hyperglycemics to demonstrate significant cardiovascular benefit in multiple cardiovascular outcomes trials (CVOTs), with benefits that are consistent across class of medication. Diabetes is a major risk factor for morbidity and mortality from cardiovascular disease. Sodium-glucose cotransporter 2 inhibitors (SGLT2-i) and glucagon-like peptide 1 receptor agonists (GLP1-ra) are the first anti-hyperglycemics to demonstrate significant cardiovascular benefit. Given the unique side effect and benefit profiles, appropriate consideration of these agents with a focus on cardiovascular risk reduction requires an individualized approach.

European journal of preventive cardiology. 2019;(2_suppl):73-80
Abstract
Type 2 diabetes mellitus is a major risk factor for developing cardiovascular disease, and many patients with diabetes have prevalent cardiovascular complications. Recent cardiovascular outcome clinical trials suggest that certain new glucose-lowering drugs are accompanied by additional cardioprotective properties. Indeed, selected glucagon-like peptide-1 receptor agonists have a proved cardiovascular benefit in terms of a reduced incidence of ischaemic events, while sodium/glucose co-transporter-2 inhibitors have also shown significant protection, with a striking effect on heart failure and renal endpoints. These findings have been integrated in recent guidelines which now recommend prescribing (when initial metformin monotherapy fails) a glucagon-like peptide-1 receptor agonist or a sodium/glucose co-transporter-2 inhibitor with clinical trial-confirmed benefit in patients with diabetes and atherosclerotic cardiovascular disease, and a sodium/glucose co-transporter-2 inhibitor in such patients with heart failure or chronic kidney disease at initial stages. Furthermore, the new 2019 European Society of Cardiology guidelines in collaboration with the European Association for the Study of Diabetes recommend a glucagon-like peptide-1 receptor agonist or a sodium/glucose co-transporter-2 inhibitor in treatment-naive patients with type 2 diabetes mellitus with pre-existing cardiovascular disease or at high cardiovascular risk. Future research will disentangle the mechanisms underpinning these beneficial effects and will also establish to what extent these results are generalisable to the whole diabetes population. In the meantime, available evidence should prompt a wide diffusion of these two classes of drugs among patients with diabetes and cardiovascular disease. Here, we briefly summarise recent findings emerging from cardiovascular outcome clinical trials, discuss their impact on treatment algorithms and propose new possible approaches to improve our knowledge further regarding the cardiovascular effect of glucose-lowering medications.

Abstract
OBJECTIVES Scientific literature about the combination of glucagon-like peptide-1 receptor agonists (GLP-1ra) and sodium-glucose cotransporter 2 (SGLT2) inhibitors in older patients is scarce. We sought to assess the real-world efficacy and safety of SGLT2 inhibitors and GLP-1ra combination therapy in older patients (>65 years of age). METHODS This was an observational, prospective, multicenter study based on clinical practice. Patients were stratified according to tertiles of baseline glycated hemoglobin (A1C) levels and to treatment schedule. RESULTS We included 113 patients (65.5% men, mean age 70.4±8.8 years). The body mass index was 36.5 (±6.6) kg/m2. The baseline A1C level was 8.0% (±1.2%). At the 6-month follow up, we found a significant reduction in A1C levels (-1.1%; p<0.0001), body mass index (-2.1 kg/m2; p<0.00003) and systolic blood pressure (-13 mmHg; p<0.000005). Patients who had the highest baseline A1C levels (≥8.4%) showed greater improvement in A1C levels (p<0.0001), weight (p<0.0001) and quality-of-life scores (p<0.0001). The greatest reduction in A1C levels and weight was seen in patients who started both drugs simultaneously (p<0.0001). The second greatest reduction was seen when GLP-1ra was added to previous treatment with an SGLT2i (p<0.0001). Also of note was a decrease in systolic blood pressure in patients for whom an SGLT2i was added to previous GLP-1ra treatment (p<0.0001). Of the patients, 34.3% achieved the combined endpoint of A1C levels <7% and weight loss ≥5% without hypoglycemia. CONCLUSIONS This study's findings provide evidence of clinically meaningful reductions in A1C level, body weight and systolic blood pressure in older patients with type 2 diabetes who are taking combined regimens. The dropout and hypoglycemia rates were minimal, and treatment was tolerated well.

Abstract
AIMS: The aim of the present study was to quantitate the hypoglycaemic effects of dipeptidyl peptidase-4 inhibitors (DPP-4i), glucagon-like peptide-1 receptor agonists (GLP-1r) and sodium glucose cotransporter 2 inhibitors (SGLT2i) as add-on treatments to metformin monotherapy in patients with type 2 diabetes mellitus (T2DM) using a model-based meta-analysis (MBMA). METHODS A systematic literature search of public databases was conducted to develop models that describe the time courses of the fasting plasma glucose (FPG)- and haemoglobin A1c (HbA1c)-lowering effects of three antidiabetic classes using NONMEM 7.3.0. RESULTS Seventy-six publications were eligible for this study, and 873 FPG and 1086 HbA1c values were collected. We developed a physiological indirect response model that described the time courses of FPG and HbA1c and simulated reductions in these values 90 days after the initiation of add-on treatments. FPG and HbA1c reductions with once weekly exenatide, liraglutide and dulaglutide were greater than those with other drugs. Mean changes from baseline FPG and HbA1c with these drugs were as follows: exenatide (-22.5 and -16.6%), liraglutide (-22.1 and -16.3%), and dulaglutide (-19.3 and -14.3%). The hypoglycaemic effects of DPP-4i and SGLT2i were similar. CONCLUSIONS Once weekly exenatide, liraglutide and dulaglutide provided better hypoglycaemic effects among the antidiabetic drugs analysed. Long-acting GLP-1r appears to be more useful for T2DM patients inadequately controlled with metformin monotherapy.
