Longitudinal efficacy of Ertugliflozin in type 2 diabetes mellitus: a meta-analysis of randomized controlled trials.

INTRODUCTION: Ertugliflozin, a sodium-glucose cotransporter-2 inhibitor, seems to improve glycemic control in type 2 diabetes mellitus (T2DM). We aim to evaluate the efficacy of Ertugliflozin across multiple time intervals (18, 26, and 52 weeks) in T2DM patients. METHODS: A literature search was conducted on electronic databases. Data was extracted from eligible studies at both 5 mg and 15 mg doses in monotherapy and as add-on therapy. Cochrane RevMan was used to perform the meta-analysis. RESULTS: Ertugliflozin, at both 5 mg and 15 mg doses, demonstrated a significant improvement in HbA1c levels at 18 weeks 5 mg [P = 0.00001], 15 mg [P = 0.05], and at 26 weeks in monotherapy 5 mg [P = 0.006], monotherapy 15 mg [P = 0.006], 5 mg as add-on therapy [P = 0.00001], 15 mg add-on therapy [P = 0.00001] respectively. At 52 weeks, the reduction in HbA1c was significant in 15 mg add-on therapy [P = 0.0001]. Additionally, ertugliflozin as an add-on therapy also led to a significant reduction in FPG, body weight, and systolic blood pressure. CONCLUSION: Ertugliflozin showed clinical efficacy in improving glycemic control, fasting plasma glucose, body weight, and systolic blood pressure in T2DM patients over the studied time intervals compared to placebo.

SGLT2 inhibitors: an evidence-based update on cardiovascular implications.

INTRODUCTION: Sodium Glucose co-Transporter 2 (SGLT2) inhibitors (also known as 'gliflozins') represent a cornerstone to treat diabetes mellitus. Moreover, recent randomized clinical trials have demonstrated important cardioprotective effects of gliflozins, independent of the presence of diabetes. Herein, we summarize the recent therapeutic progress in the cardiovascular field obtained with SGLT2 inhibitors. AREA COVERED: We critically examine the rationale and results of recent clinical studies examining the effects of SGLT2 inhibitors on cardiovascular outcomes, along with a brief overview of the main ongoing trials that have been designed in order to answer the many pending questions in the field of gliflozins and cardiovascular disease. EXPERT OPINION: The favorable results of several clinical trials have broadened the therapeutic scenario for SGLT2 inhibitors, opening, at the same time, new challenges. Additionally, recent preclinical findings have evidenced off-target effects of SGLT2 inhibitors.

Dose-dependent renoprotection efficacy of sglt2 inhibitors in type 2 diabetes: systematic review and network meta-analysis.

AIM: To compare the relative effects of different dosages of sodium-glucose cotransport inhibitors (SGLT2i) for renoprotection in Type 2 diabetes mellitus. METHODS: The study searched different databases (PubMed, Embase, Scopus, and Web of Science) for studies comparing dose-dependent renoprotective efficacy defined as a decline in eGFR with the different "-flozins namely Empagliflozin, Canagliflozin, Dapagliflozin, Ertugliflozin, Ipragliflozin, Luseogliflozin, Remogliflozin and Sotagliflozin. The studies were compared with the Bayesian approach of network meta-analysis coupled with the random-effect model using the Cochrane risk of bias tool (RoB 2.0), and the surface under the cumulative ranking curve (SUCRA) score was allotted to each dosage of different SGLT-2i. RESULTS: A total of 43,434 citations were identified, out of which forty-five randomized trials with 48,067 patients, mentioning the flozin dose and eGFR as an endpoint, were found to be eligible for further analysis. The median duration of the follow-up in the trials was 12 months (IQR 5.5-16 months). Canagliflozin 100 mg demonstrated distinct eGFR benefit with an odds ratio of 2.3 (CI 0.72-3.9) compared to placebo. A statistically non-significant eGFR benefit was observed with all other "-flozins." Canagliflozin 100 mg drug dose category showed the highest sucra rank probability score of 93%, followed by the Canagliflozin 300 mg and Dapagliflozin 5 mg with sucra rank probability scores of 69% and 65%, respectively. The Flozin-dose assessment against eGFR was similar to the albumin-creatinine ratios as the secondary endpoint in the SUCRA ranking. CONCLUSION: The renoprotective efficacy of SGLT2i is independent of the incremental doses suggesting lower doses may suffice for renal outcomes.

Effects of Ertugliflozin on Kidney Outcomes in Patients With Heart Failure at Baseline in the Evaluation of Ertugliflozin Efficacy and Safety Cardiovascular Outcomes (VERTIS CV) Trial.

Introduction: In the eValuation of ERTugliflozin effIcacy and Safety CardioVascular outcomes (VERTIS CV) trial (NCT01986881), patients with type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular disease (ASCVD) were randomized (1:1:1) to placebo, ertugliflozin 5 mg or 15 mg (doses pooled for analyses as prospectively planned). In this post hoc analysis, the effects of ertugliflozin on kidney outcomes were assessed in analyses stratified by baseline heart failure (HF). Methods: Baseline HF was defined as a history of HF or prerandomization left ventricular ejection fraction ≤45%. Outcomes included estimated glomerular filtration rate (eGFR) over time, total 5-year eGFR slopes and time to first event of a prespecified exploratory kidney composite outcome of sustained ≥40% decrease from baseline eGFR, chronic kidney replacement therapy, or kidney death. All analyses were stratified by baseline HF status. Results: Compared with no-HF at baseline (n = 5807; 70.4%), patients with HF (n = 2439; 29.6%) had a notably faster rate of eGFR decline, which is unlikely to be explained by the slightly lower baseline eGFR in that group. Ertugliflozin treatment resulted in a slower rate of eGFR decline in both subgroups; total placebo-adjusted 5-year eGFR slopes (ml/min per 1.73 m2 per year [95% confidence intervals; CI]) were 0.96 (0.67-1.24) and 0.95 (0.76-1.14) for HF and no-HF subgroups, respectively. The placebo HF (vs. placebo no-HF) subgroup had a higher incidence of the composite kidney outcome (35/834 [4.20%] vs. 50/1913 [2.61%]). Hazard ratios (95% CI) for the effect of ertugliflozin on the composite kidney outcome did not differ significantly between HF and no-HF subgroups: 0.53 (0.33-0.84) and 0.76 (0.53-1.08), respectively (P interaction  = 0.22). Conclusion: Although patients with HF at baseline had a faster rate of eGFR decline in VERTIS CV, the beneficial effects of ertugliflozin on kidney outcomes did not differ when stratified by baseline HF.

Hypertriglyceridemia in equines with refractory hyperinsulinemia treated with SGLT2 inhibitors.

Background: Sodium-Glucose CoTransporter-2 (SGLT2) inhibitors, the -flozin group of drugs, which block glucose reuptake in the renal proximal tubule, are being increasingly used off-label to treat horses with refractory hyperinsulinemia. After 2 years of use by animals in our group, a horse on canagliflozin was incidentally noted to be hyperlipemic. Case Description: We have been following a cohort of equines (n = 20) treated with SGLT2 inhibitors due to refractory hyperinsulinemia. The animals are owned by members of the Equine Cushing's and Insulin Resistance Group and treated by their attending veterinarians. The index case was a 23 years old gelding with a 2 years history of recurring laminitis that began canagliflozin therapy to control hyperinsulinemia which was no longer responsive to metformin. Between 6 and 10 weeks post start of therapy, significant weight loss was noticed. Two days later he was hospitalized with colic symptoms and hyperlipemia but was bright, alert, and eating well throughout. Canagliflozin was discontinued and triglycerides returned to normal reference values within 10 days. A subsequent study of 19 other horses on SGLT2 inhibitors revealed varying degrees of hypertriglyceridemia, all asymptomatic. Conclusion: While this class of drugs holds great promise for cases of refractory hyperinsulinemia and laminitis that do not respond to diet or metformin therapy, hypertriglyceridemia is a potential side effect. In our experience, animals remained asymptomatic and eating well. Further study of hypertriglyceridemia in horses on SGLT2 inhibitors and the possible mitigating effect of diet is indicated. To our knowledge, this is the first report of hypertriglyceridemia with canagliflozin treatment in equines.

Neutral effects of SGLT2 inhibitors in acute coronary syndromes, peripheral arterial occlusive disease, or ischemic stroke: a meta-analysis of randomized controlled trials.

BACKGROUND: Patients with type 2 diabetes are at increased risk for cardiovascular diseases. Sodium-glucose transport 2 inhibitors (SGLT2i) have been shown to enhance cardiovascular health since their debut as a second-line therapy for diabetes. Acute coronary syndrome (ACS), peripheral arterial occlusive disease (PAOD), and ischemic stroke (IS) are types of atherosclerotic cardiovascular disease (ASCVD), although the benefits of treating these disorders have not been shown consistently. METHODS: We searched four databases (PubMed, Embase, the Cochrane library, and clinicaltrial.gov) for randomized clinical trials (RCTs) until November of 2022. Comparisons were made between SGLT2i-treated and control individuals with type 2 diabetes. Primary outcomes were ACS, PAOD, and IS; secondary outcomes included cardiovascular mortality and all-cause mortality. Risk ratio (RR) and 95% confidence intervals (CI) were determined using a fixed effects model. Cochrane's risk-of-bias (RoB2) instrument was used to assess the validity of each study that met the inclusion criteria. RESULTS: We enrolled 79,504 patients with type 2 diabetes from 43 RCTs. There was no difference in the risk of ACS (RR = 0.97, 95% CI 0.89-1.05), PAOD (RR = 0.98, 95% CI 0.78-1.24), or IS (RR = 0.95, 95% CI 0.79-1.14) among patients who took an SGLT2i compared to those who took a placebo or oral hypoglycemic drugs. Subgroup analysis revealed that none of the SGLT2i treatments (canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin) significantly altered outcomes when analyzed separately. Consistent with prior findings, SGLT2i reduced the risk of cardiovascular mortality (RR = 0.85, 95% CI 0.77-0.93) and all-cause mortality (RR = 0.88, 95% CI 0.82-0.94). CONCLUSION: Our results appear to contradict the mainstream concepts regarding the cardiovascular effects of SGLT2i since we found no significant therapeutic benefits in SGLT2i to reduce the incidence of ACS, PAOD, or IS when compared to placebo or oral hypoglycemic drugs.

SGLT2 Inhibitors in Diabetic and Non-Diabetic Chronic Kidney Disease.

Results from recent randomized controlled trials on inhibitors of the sodium-glucose cotransporter 2 (SGLT2) have determined a paradigm shift in the treatment of patients with type 2 diabetes mellitus. These agents have been shown not only to ameliorate metabolic control, but also to independently protect from cardiovascular events and to reduce the progression of chronic kidney disease (CKD) in these patients. The magnitude of the nephroprotective effect observed in these studies is likely to make SGLT2 inhibitors the most impactful drug class for the treatment of diabetic patients with CKD since the discovery of renin-angiotensin system inhibitors. Even more surprisingly, SGLT2 inhibitors have also been shown to slow CKD progression in non-diabetic individuals with varying degrees of proteinuria, suggesting that activation of SGLT2 is involved in the pathogenesis of CKD independent of its etiology. As indications continue to expand, it is still unclear whether the observed benefits of SGLT2 inhibitors may extend to CKD patients at lower risk of progression and if their association with other agents may confer additional protection.

Efficacy and Safety of Ertugliflozin Added to Metformin: A Pooled Population from Asia with Type 2 Diabetes and Overweight or Obesity.

INTRODUCTION: The efficacy and safety of ertugliflozin have not been well characterized in Asian populations with type 2 diabetes (T2D) and overweight or obesity as defined by the Chinese Diabetes Society [body mass index (BMI) ≥ 24 kg/m2]. METHODS: These post hoc analyses of pooled data from two randomized, double-blind, 26-week studies assessed the efficacy and safety of ertugliflozin (5 mg or 15 mg) compared with placebo in participants from Asia with T2D and baseline BMI ≥ 24 kg/m2, with inadequate glycemic control on metformin. Longitudinal analyses were used to calculate least squares (LS) mean [95% confidence interval (CI)] change from baseline in glycemic indices and body weight. The proportions of participants achieving efficacy targets and experiencing adverse events (AEs) were assessed. RESULTS: The 445 participants had a mean age of 55.5 years, T2D duration 6.6 years, glycated hemoglobin (HbA1c) 8.1%, and BMI 27.6 kg/m2. At week 26, placebo-adjusted LS mean (95% CI) changes from baseline for ertugliflozin 5 mg and 15 mg, respectively, were - 0.78% (- 0.95% to - 0.61%) and - 0.80% (- 0.98% to - 0.63%) for HbA1c, and - 1.74 kg (- 2.29 kg to - 1.19 kg) and - 2.04 kg (- 2.60 kg to - 1.48 kg) for body weight. A greater proportion of participants receiving ertugliflozin 5 mg and 15 mg versus placebo, respectively, achieved HbA1c < 7.0% (42.1% and 46.3% vs. 13.9%), body weight reduction ≥ 5% (35.5% and 38.3% vs. 11.1%), and systolic blood pressure < 130 mmHg (42.4% and 34.5% vs. 21.7%). The proportion of participants with AEs was 52.6% (ertugliflozin 5 mg), 52.3% (ertugliflozin 15 mg), and 55.6% (placebo). CONCLUSIONS: In participants from Asia with T2D inadequately controlled by metformin monotherapy, and BMI ≥24 kg/m2, ertugliflozin (5 mg or 15 mg) resulted in greater glycemic and body weight reductions compared with placebo and was generally well tolerated. TRIAL REGISTRATION: Clinicaltrials.gov identifiers NCT02033889, NCT02630706.

The sodium glucose co-transporter 2 inhibitor ertugliflozin for Alzheimer's disease: Inhibition of brain insulin signaling disruption-induced tau hyperphosphorylation.

An antidiabetic agent sodium glucose co-transporter 2 (SGLT2) inhibitor ertugliflozin has been revealed to bind to catalytic anionic site of acetylcholinesterase (AChE), which is considered to be associated with the cognitive decline in neurodegenerative diseases, such as Alzheimer's disease (AD). The aim of the present study was thus to probe the effect of ertugliflozin on AD. Intracerebroventricular injection of streptozotocin (STZ/i.c.v) (3 mg/kg) was done bilaterally in male Wistar rats at 7-8 weeks of age. Two treatment doses (5 mg/kg and 10 mg/kg) of ertugliflozin were given intragastrically to STZ/i.c.v-induced rats for 20 days daily for behavioral assessment. Biochemical estimations of cholinergic activity, neuronal apoptosis, mitochondrial function and synaptic plasticity were performed. Behavioral results with ertugliflozin treatment revealed attenuation of cognitive deficit. Ertugliflozin also inhibited hippocampal AChE activity, downregulated pro-apoptotic marker expression, as well as mitigated mitochondrial dysfunction and synaptic damage in STZ/i.c.v rats. Importantly, we found that the hyperphosphorylation of tau in the hippocampus of STZ/i.c.v rats was decreased after oral administration of ertugliflozin, which was accompanied by decreased Phospho.IRS-1Ser307/Total.IRS-1 ratio and increased Phospho.AktSer473/Total.Akt and Phospho.GSK3ßSer9/Total.GSK3ß ratios. Our results indicated that treatment with ertugliflozin reversed AD pathology, which may be associated with inhibition of insulin signaling disruption-induced tau hyperphosphorylation.

SGLT2 inhibitor ertugliflozin decreases elevated intracellular sodium, and improves energetics and contractile function in diabetic cardiomyopathy.

BACKGROUND: Elevated myocardial intracellular sodium ([Na+]i) was shown to decrease mitochondrial calcium ([Ca2+]MITO) via mitochondrial sodium/calcium exchanger (NCXMITO), resulting in decreased mitochondrial ATP synthesis. The sodium-glucose co-transporter 2 inhibitor (SGLT2i) ertugliflozin (ERTU) improved energetic deficit and contractile dysfunction in a mouse model of high fat, high sucrose (HFHS) diet-induced diabetic cardiomyopathy (DCMP). As SGLT2is were shown to lower [Na+]i in isolated cardiomyocytes, we hypothesized that energetic improvement in DCMP is at least partially mediated by a decrease in abnormally elevated myocardial [Na+]i. METHODS: Forty-two eight-week-old male C57BL/6J mice were fed a control or HFHS diet for six months. In the last month, a subgroup of HFHS-fed mice was treated with ERTU. At the end of the study, left ventricular contractile function and energetics were measured simultaneously in isolated beating hearts by 31P NMR (Nuclear Magnetic Resonance) spectroscopy. A subset of untreated HFHS hearts was perfused with vehicle vs. CGP 37157, an NCXMITO inhibitor. Myocardial [Na+]i was measured by 23Na NMR spectroscopy. RESULTS: HFHS hearts showed diastolic dysfunction, decreased contractile reserve, and impaired energetics as reflected by decreased phosphocreatine (PCr) and PCr/ATP ratio. Myocardial [Na+]i was elevated > 2-fold in HFHS (vs. control diet). ERTU reversed the impairments in HFHS hearts to levels similar to or better than control diet and decreased myocardial [Na+]i to control levels. CGP 37157 normalized the PCr/ATP ratio in HFHS hearts. CONCLUSIONS: Elevated myocardial [Na+]i contributes to mitochondrial and contractile dysfunction in DCMP. Targeting myocardial [Na+]i and/or NCXMITO may be an effective strategy in DCMP and other forms of heart disease associated with elevated myocardial [Na+]i.

Ertugliflozin Delays Insulin Initiation and Reduces Insulin Dose Requirements in Patients With Type 2 Diabetes: Analyses From VERTIS CV.

CONTEXT: VERTIS CV evaluated the cardiovascular safety of ertugliflozin in patients with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD). OBJECTIVE: The aim of these analyses was to assess the insulin requirements of VERTIS CV patients over the trial duration. METHODS: Patients received ertugliflozin 5 mg, 15 mg, or placebo once daily; mean follow-up was 3.5 years. Time to insulin initiation in patients who were insulin naïve at baseline, change in insulin dose in patients receiving baseline insulin, and hypoglycemia incidence in both patient groups were assessed. RESULTS: In VERTIS CV, mean duration of type 2 diabetes was 13.0 years; glycated hemoglobin was 8.2%. Among 4348 (53%) insulin-naïve patients, the likelihood of insulin initiation was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: hazard ratio [HR] 0.70, 95% CI 0.58-0.84; ertugliflozin 15 mg: HR 0.64, 95% CI 0.53-0.78). Time to insulin initiation was delayed with ertugliflozin; the estimated delay in reaching a 10% cumulative incidence of new insulin initiations vs placebo was 399 days with ertugliflozin 5 mg and 669 days with ertugliflozin 15 mg. Among 3898 (47%) patients receiving baseline insulin, the likelihood of requiring a ≥20% increase in insulin dose was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: HR 0.62, 95% CI 0.52-0.75; ertugliflozin 15 mg: HR 0.51, 95% CI 0.41-0.62). The incidence of hypoglycemia events was not increased with ertugliflozin treatment. CONCLUSION: In VERTIS CV patients, ertugliflozin reduced the likelihood of insulin initiation, delayed the time to insulin initiation by up to ∼1.8 years, and reduced insulin dose requirements vs placebo, without increasing hypoglycemia events.

Sodium-glucose co-transporter 2 inhibitors in patients with chronic kidney disease.

Diabetes drives an increasing burden of cardiovascular and renal disease worldwide, motivating the search for new hypoglycemic agents that confer cardiac and renal protective effects. Although initially developed as hypoglycemic agents, sodium-glucose co-transporter 2 (SGLT-2) inhibitors have since been studied in patients with and without diabetes for the management of heart failure and chronic kidney disease. A growing body of evidence supports the efficacy and safety of SGLT-2 inhibitors in patients with chronic kidney disease (CKD), based on complex mechanisms of action that extend far beyond glucosuria and that confer beneficial effects on cardiovascular and renal hemodynamics, fibrosis, inflammation, and end-organ protection. This review focuses on the pharmacology and pathophysiology of SGLT-2 inhibitors in patients with CKD, as well as their cardiovascular and renal effects in this population. We are focusing on the five agents that have been tested in cardiovascular outcome trials and that have been approved either in Europe or in North America: empagliflozin, dapagliflozin, canagliflozin, ertugliglozin, and sotagliflozin.

Chromatographic study of sitagliptin and ertugliflozin under quality-by-design paradigm

Abstract The present study entails the systematic development and validation of a stability-indicating RP-HPLC method for the analysis of sitagliptin and ertugliflozin in a fixed-dose combination. Analytical quality by design (AQbD) concepts were used to define critical method variables, employing Pareto risk assessment and a Placket-Burman screening design, preceded by a Box-Behnken design with response surface analysis to optimise critical method parameters such as % acetonitrile (X1), buffer pH (X2) and column oven temperature (X3). Multiple response optimisation (Derringer's desirability) of variables was accomplished by studying critical analytical attributes, such as resolution, retention time and theoretical plates. The title analytes were separated effectively on a PRONTOSIL C18 column at 37 °C using a mobile phase of acetonitrile:acetate buffer, pH 4.4 (36:64 percent v/v), pumped at a flow rate of 1 mL/min, and UV detection at 225 nm. Linearity was observed over a concentration range of 25-150 µg/mL and 3.75-22.5 µg/mL at retention times of 2.82 and 3.92 min for sitagliptin and ertugliflozin, respectively. The method obeyed all validation parameters of the ICH Q2(R1) guidelines. The proposed robust method allows the study of the selected drugs in pharmaceutical dosage forms as well as in drug stability studies under various stress conditions.

Role of Ertugliflozin in the Management of Diabetes Mellitus.

The novel oral sodium-glucose cotransporter-2 (SGLT2) inhibitor Ertugliflozin (SteglatroTM) is introduced as a monotherapy or in conjunction with another antidiabetic drug regimen for the treatment of type 2 diabetes mellitus (T2DM).Additional safe and efficient treatment options for patients and physicians are of utmost importance as the incidence of T2DM rises. As a standalone therapy or an adjunctive treatment, ertugliflozin seems to be a reliable and safe option.This narrative review seeks to report and analyze ertugliflozin's effectiveness, safety, cardiovascular (CV), and renal outcomes in T2DM. Various combinations of drugs and drug classes have been tried to reduce mortality and comorbidities associated with the use of antidiabetic agents, especially cardiogenic events and renal diseases. With the administration of hypoglycemic drugs like ertugliflozin and the regulation of blood sugar levels, the incidence of therapy-induced hypertension, obesity, and dose-related hypoglycemia has been reduced to a significant extent. Additionally, ertugliflozin prevents hypertension caused by prolonged antidiabetic drug intake, which is advantageous for lowering the chances of end-stage cardiac events in type 2 diabetic patients. As far as the renal safety profile of ertugliflozin is concerned, it has been associated with the maintenance of eGFR (estimated glomerular filtration rate) and a decreased UACR (urine albumin-to-creatinine ratio) in patients with T2DM and coronary artery disease, which reduces the incidence of renal adverse effects due to long-term medication. As a result of common pathophysiological mechanisms, SGLT2 inhibitors represent a feasible therapeutic option and are advantageous for patients with type 1 and type 2 DM in terms of cardiovascular and renal outcomes.

The Role of Sodium-Glucose Cotransporter-2 Inhibition in Heart Failure with Preserved Ejection Fraction.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are a novel class of antidiabetic mediations found to also reduce cardiovascular morbidity and mortality and hospitalization for heart failure. Positive results from the EMPEROR-Preserved (empagliflozin) and PRESERVED-HF (dapagliflozin) studies led to recommendations for SGLT2 inhibitors in HFpEF within major international heart failure guidelines. However, studies of ipragliflozin and luseogliflozin, agents approved outside the United States (U.S.), reported different outcomes relative to pivotal trials and failed to realize benefits in the HFpEF population. Varying definitions of HFpEF and outcomes studied complicate the interpretation of study results. SGLT2 inhibitors may cause common adverse events (genital mycotic infections, volume depletion) in addition to rare but severe sequela, including euglycemic diabetic ketoacidosis, Fournier's gangrene, and lower limb amputation. While evidence of CV benefits grows, SGLT2 inhibitor prescribing has lagged, particularly among patients without diabetes. In the U.S., high cost and administrative hurdles may contribute to decreased patient and clinician uptake of this drug class. Future trial results and clinical experience with SGLT2 inhibitors may lead to expanded use and greater uptake among patients with heart failure.
