Comparing the Efficacy and Safety of Glucagon-Like Peptide 1 Receptor Agonists with Sodium-Glucose Cotransporter 2 Inhibitors for Obese Type 2 Diabetes Patients Uncontrolled on Metformin: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

ABSTRACT: Introduction To conduct the first meta-analysis of randomized controlled trials (RCTs) comparing glucagon-like peptide 1 receptor agonists (GLP-1RAs) with sodium-glucose cotransporter 2 inhibitors (SGLT-2is) for obese type 2 diabetes (T2D) patients uncontrolled on metformin. Methods We searched Pubmed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Ovid, and Web of Science from inception to May 14, 2020, without language restrictions for eligible RCTs. The primary outcome is the mean change from baseline in glycated haemoglobin (HbA1c). Results Totally, 3 RCTs enrolled 2066 patients were identified. Compared with SGLT-2is, treatment with GLP-1RAs achieved significant reduced HbA1c by 0.40% (95% CI: ?0.54, ?0.25; p < 0.00001), fasting blood glucose (FBG) by 0.17?mmol/L (95% CI: ?0.31, ?0.04; p=0.01), and postprandial blood glucose (PBG) by 0.32?mmol/L (95% CI: ?0.49, ?0.14; p=0.0003) for obese T2D patients uncontrolled on metformin. The significant benefit of weight loss was seen in semaglutide (MD: ?0.75; 95% CI: ?1.18, ?0.31; p < 0.0007). No significant difference was detected between GLP-1RAs and SGLT-2is in overall adverse events (RR: 1.03; 95% CI: 0.98, 1.09; p=0.76), but gastrointestinal events showed higher occurrence in GLP-1RAs groups compared with SGLT-2is (RR: 1.62; 95% CI: 1.37, 1.93; p < 0.00001). Subgroup analyses revealed that follow-up time did not statistically influence glycemic control. Conclusion GLP-1RAs are superior to SGLT-2is for obese T2D patients uncontrolled on metformin in glycemic control without an increase in adverse events except for a higher occurrence in gastrointestinal events. Future large longer-term follow-up clinical trials are needed to provide more evidence about the sustainable effects and safety of GLP-1RAs compared with SGLT-2is.

Project description:ObjectiveTo evaluate sodium-glucose cotransporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists in patients with type 2 diabetes at varying cardiovascular and renal risk.DesignNetwork meta-analysis.Data sourcesMedline, Embase, and Cochrane CENTRAL up to 11 August 2020.Eligibility criteria for selecting studiesRandomised controlled trials comparing SGLT-2 inhibitors or GLP-1 receptor agonists with placebo, standard care, or other glucose lowering treatment in adults with type 2 diabetes with follow up of 24 weeks or longer. Studies were screened independently by two reviewers for eligibility, extracted data, and assessed risk of bias.Main outcome measuresFrequentist random effects network meta-analysis was carried out and GRADE (grading of recommendations assessment, development, and evaluation) used to assess evidence certainty. Results included estimated absolute effects of treatment per 1000 patients treated for five years for patients at very low risk (no cardiovascular risk factors), low risk (three or more cardiovascular risk factors), moderate risk (cardiovascular disease), high risk (chronic kidney disease), and very high risk (cardiovascular disease and kidney disease). A guideline panel provided oversight of the systematic review.Results764 trials including 421 346 patients proved eligible. All results refer to the addition of SGLT-2 inhibitors and GLP-1 receptor agonists to existing diabetes treatment. Both classes of drugs lowered all cause mortality, cardiovascular mortality, non-fatal myocardial infarction, and kidney failure (high certainty evidence). Notable differences were found between the two agents: SGLT-2 inhibitors reduced admission to hospital for heart failure more than GLP-1 receptor agonists, and GLP-1 receptor agonists reduced non-fatal stroke more than SGLT-2 inhibitors (which appeared to have no effect). SGLT-2 inhibitors caused genital infection (high certainty), whereas GLP-1 receptor agonists might cause severe gastrointestinal events (low certainty). Low certainty evidence suggested that SGLT-2 inhibitors and GLP-1 receptor agonists might lower body weight. Little or no evidence was found for the effect of SGLT-2 inhibitors or GLP-1 receptor agonists on limb amputation, blindness, eye disease, neuropathic pain, or health related quality of life. The absolute benefits of these drugs vary substantially across patients from low to very high risk of cardiovascular and renal outcomes (eg, SGLT-2 inhibitors resulted in 3 to 40 fewer deaths in 1000 patients over five years; see interactive decision support tool (https://magicevidence.org/match-it/200820dist/#!/) for all outcomes.ConclusionsIn patients with type 2 diabetes, SGLT-2 inhibitors and GLP-1 receptor agonists reduced cardiovascular and renal outcomes, with some differences in benefits and harms. Absolute benefits are determined by individual risk profiles of patients, with clear implications for clinical practice, as reflected in the BMJ Rapid Recommendations directly informed by this systematic review.Systematic review registrationPROSPERO CRD42019153180.

Project description:Background Sodium-glucose cotransporter-2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) mitigate cardiovascular risk in individuals with type 2 diabetes, but most eligible patients do not receive them. We characterized temporal trends in SGLT2i and GLP-1RA use by cardiologists compared with other groups of clinicians. Methods and Results We conducted a descriptive analysis of serial, cross-sectional data derived from IQVIA's National Prescription Audit, a comprehensive audit capturing ≈90% of US retail prescription dispensing and projected to population-level data, to estimate monthly SGLT2is and GLP-1RAs dispensed from January 2015 to December 2020, stratified by prescriber specialty and molecule. We also used the American Medical Association's Physician Masterfile to calculate average annual SGLT2is and GLP-1RAs dispensed per physician. Between January 2015 and December 2020, a total of 63.2 million SGLT2i and 63.4 million GLP-1RA prescriptions were dispensed in the United States. Monthly prescriptions from cardiologists increased 12-fold for SGLT2is (from 2228 to 25 815) and 4-fold for GLP-1RAs (from 1927 to 6981). Nonetheless, cardiologists represented only 1.5% of SGLT2i prescriptions and 0.4% of GLP-1RA prescriptions in 2020, while total use was predominated by primary care physicians/internists (57% of 2020 SGLT2is and 52% of GLP-1RAs). Endocrinologists led in terms of prescriptions dispensed per physician in 2020 (272 SGLT2is and 405 GLP-1RAs). Cardiologists, but not noncardiologists, increasingly used SGLT2is over GLP-1RAs, with accelerated uptake of empagliflozin and dapagliflozin coinciding with their landmark cardiovascular outcomes trials and subsequent US Food and Drug Administration label expansions. Conclusions While use of SGLT2is and GLP-1RAs by cardiologists in the United States increased substantially over a 6-year period, cardiologists still account for a very small proportion of all use, contributing to marked undertreatment of individuals with type 2 diabetes at high cardiovascular risk.

Project description:BackgroundSodium glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have been demonstrated to be able to improve the cardiovascular and renal prognosis in patients with type 2 diabetes (T2D). However, the relative efficacy of various SGLT2 inhibitors and GLP-1 RAs on cardiorenal outcomes is unestablished.MethodsWe searched PubMed and Embase for relevant cardiovascular or renal outcome trials (CVOTs). Endpoints of interest were major adverse cardiovascular events (MACE), stroke, myocardial infarction (MI), cardiovascular death (CVD), all-cause death (ACD), kidney function progression (KFP), and hospitalization for heart failure (HHF). Bayesian network meta-analysis was conducted to produce pooled hazard ratio (HR) and 95% confidence interval (CI). We calculated the probability values of surface under the cumulative ranking curve to rank active and placebo interventions.ResultsFourteen COVTs were included in analysis. Sotagliflozin (HR 0.76, 95% CI 0.61-0.94), subcutaneous semaglutide, and albiglutide lowered MACE versus lixisenatide among others. Sotagliflozin (HR 0.59, 95% CI 0.40-0.89), canagliflozin, and empagliflozin lowered HHF versus subcutaneous semaglutide among others. Dapagliflozin and empagliflozin lowered KFP versus exenatide among others. Empagliflozin and oral semaglutide lowered CVD versus dapagliflozin among others. Sotagliflozin (HR 0.65, 95% CI 0.47-0.91) and albiglutide lowered MI versus ertugliflozin among others. Sotagliflozin (HR 0.56, 95% CI 0.37-0.85) and subcutaneous semaglutide lowered stroke versus empagliflozin among others. Oral semaglutide and empagliflozin lowered ACD versus subcutaneous semaglutide among others. The maximum surface under the cumulative ranking curve values followed sotagliflozin, subcutaneous semaglutide, and albiglutide in lowering MACE; sotagliflozin, canagliflozin, and empagliflozin in lowering HHF; dapagliflozin and empagliflozin in lowering KFP; empagliflozin and oral semaglutide in lowering CVD; sotagliflozin and albiglutide in lowering MI; sotagliflozin and subcutaneous semaglutide in lowering stroke; and oral semaglutide and empagliflozin in lowering ACD.ConclusionsThis updated network meta-analysis reproduced the findings in the first network meta-analysis, and moreover revealed that sotagliflozin was one of the most effective drugs as for lowering MI, stroke, MACE, and HHF, whereas ertugliflozin was not. These findings will provide the according evidence regarding the usage of specific SGLT2 inhibitors and GLP-1 RAs in T2D patients for prevention of specific cardiorenal endpoints.
