Efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus and established cardiovascular disease using insulin: A VERTIS CV substudy

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.

Effect of Intensive Glycemic Control on Myocardial Infarction Outcome in Patients with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis

BACKGROUND

The effect of intensive glucose-lowering treatment on the risk of cardiovascular events in type 2 diabetes remains uncertain, especially the effect on the occurrence of myocardial infarction in patients with type 2 diabetes is still unclear. The purpose of this study was to conduct a systematic review and meta-analysis of relevant RCTs.

METHODS

We performed a systematic review of randomized clinical trials (RCTS) and observational studies relevant to this study question. We searched the PubMed and Cochrane databases until June 2022.

RESULTS

We included data on 14 RCTs and 144,334 patients, all of whom had type 2 diabetes. When all studies were considered, intensive glucose-lowering treatment significantly reduced the incidence of MI compared with conventional therapy and the total OR value is 0.90 (CI 0.84, 0.97; P = 0.004) when considering all the studies. When the target value of intensive glucose-lowering treatment was considered as HbA1c decrease of more than 0.5%, there was no significant protective effect on MI, the total OR value is 0.88 (CI 0.81, 0.96; P = 0.003). When considering all available RCTS, the intensive glucose-lowering treatment group had a protective effect for MACE compared to the conventional treatment group, and the total OR value is 0.92 (CI 0.88, 0.96; P < 0.00001). In the available RCTs, for the patients with a history of prior CAD, the total OR value is 0.94 (CI 0.89, 0.99; P = 0.002). And there was no difference in the incidence of hypoglycemic events between the intensive and conservative treatment groups.

CONCLUSION

Our data support the positive protective effect of glucose-lowering therapy on MI in patients with T2DM, but there is no significant effect of intensive glucose-lowering. In addition, we found no greater protective effect of enhanced glucose control in the HbA1c reduction of more than 0.5%, and no difference in the incidence of adverse events compared with the HbA1c reduction of less than 0.5%.

Growing role of SGLT2i in heart failure: evidence from clinical trials

INTRODUCTION

: There is an unmet need for therapies that improve overall mortality and morbidity for patients with preserved ejection fraction, who comprise roughly half of all heart failure (HF) cases. The growing role of sodium-glucose cotransporter-2 inhibitors (SGLT2is) in cardiovascular outcomes provide a paradigm shift in the treatment of HF.

AREAS COVERED

: This review article provides a general overview of the growing role of SGLT2is and summarizes the mechanism of action, side effects, and contraindications for the treatment of HF. We also discuss recent clinical trials measuring the effects of different SGLT2is as possible treatment options for HF with reduced ejection fraction and HF with mid-range and preserved EF. We conducted a review of all the randomized, controlled studies with SGLT2is in patients with known heart failure with and without type-2 diabetes (T2DM). We performed a literature search in PubMed, Google Scholar, the Web of Science, and the Cochrane Library while screening results by the use of titles and abstracts.

EXPERT OPINION

: The promising pathophysiological profile of SGLT2i and their role in cardioprotective effects demonstrate an invaluable discovery in the management of patients with HF irrespective of their diabetes status.

Review of pharmaceutical and therapeutic approaches for type 2 diabetes and related disorders

One of the essential diseases that are increasing in the world is type 2 diabetes (T2D), which many people around the world live with this disease. Various studies have revealed that insulin resistance, lessened insulin production has been associated with T2D, and they also show that this disease can have a genetic origin and is associated with different genes such as KCNQ1, PPAR-γ, calpain-10, ADIPOR2, TCF7L2 that can be utilized as a therapeutic target. Different therapeutic approaches and strategies such as exercise and diet, pharmacological approaches, and utilization of nanoparticles in drug delivery and gene therapy can be effective in the treatment and control of T2D. Glucagon-like peptide 1 (GLP-1) and sodium glucose cotransporter-2 (SGLT2) have both been considered as drug classes in the treatment of T2D and T2D-related diseases such as cardiovascular disease and renal disease, and have considerable influences such as diminished cardiovascular mortality in individuals with T2D, ameliorate postprandial glycaemia, ameliorate fasting glycaemia, and diminish body weight on disease treatment and improvement process. In the present review article, we have made an attempt to explore the risk factors, Genes, and diseases associated with T2D, therapeutic approaches in T2D, the influences of drugs such as Dapagliflozin, Metformin, Acarbose, Januvia (Sitagliptin), and Ertugliflozin on T2D in clinical trials and animal model studies. Research in clinical trials has promising results that support the role of these drug approaches in T2D prophylaxis and ameliorate safety even though additional clinical research is still obligatory.

Efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus and established cardiovascular disease using insulin: A VERTIS CV substudy

AIM

To assess the efficacy and safety of ertugliflozin in patients with type 2 diabetes mellitus (T2DM) and established atherosclerotic cardiovascular disease (ASCVD) inadequately controlled by insulin.

MATERIALS AND METHODS

VERTIS CV was the cardiovascular outcome study for ertugliflozin. Patients were randomly assigned to placebo, or ertugliflozin 5 mg or 15 mg once daily. We report the results of a substudy in patients on a stable dose of insulin ≥20 units/d. The primary endpoint was glycated haemoglobin (HbA1c) change from baseline to 18 weeks. Secondary endpoints were changes in fasting plasma glucose (FPG), body weight (BW), the proportion of patients with HbA1c <53 mmol/mol (<7%), systolic blood pressure (SBP), diastolic blood pressure and insulin dose.

RESULTS

Of 8246 patients randomized in VERTIS CV, 1065 were included in the substudy (68.2% men, mean [SD] age 64.8 [7.8] years, T2DM duration 16.7 [9.0] years, HbA1c 8.4 [1.0]%). At week 18, the least squares (LS) mean change from baseline in HbA1c was significantly greater with ertugliflozin 5 mg and 15 mg versus placebo (placebo-adjusted LS mean change -0.58%, 95% confidence interval [CI] -0.71, -0.44 and -0.65%, 95% CI -0.78, -0.51, respectively; P < 0.001 for both). Ertugliflozin significantly reduced FPG, BW and SBP. In women, the incidence of genital mycotic infections was higher with ertugliflozin (3.5%) versus placebo (0.0%). The incidence of symptomatic hypoglycaemia was similar across treatment groups.

CONCLUSIONS

Ertugliflozin added to insulin improved glycaemic control, BW and SBP versus placebo at 18 weeks in patients with T2DM and ASCVD.

Efficacy and Safety of Ertugliflozin in Patients With Diabetes Mellitus Inadequately Controlled by Sulfonylurea Monotherapy: a Substudy of VERTIS CV

INTRODUCTION

Sulfonylureas (SU) are commonly used antihyperglycemic agents. VERTIS CV was the cardiovascular outcome study for the sodium-glucose cotransporter 2 inhibitor ertugliflozin. Enrollment of patients in VERTIS CV occurred in two sequential cohorts (Cohort 1 and Cohort 2).

METHODS

This substudy assessed the efficacy and safety of adding ertugliflozin to SU monotherapy. The primary endpoint was the change in HbA1c from baseline at 18 weeks.

RESULTS

Among the 8246 patients who were randomized in VERTIS CV, 157 patients in Cohort 1 and 135 patients in Cohort 2 were on SU monotherapy at baseline. In the prespecified analysis (Cohort 1 only), the least squares (LS) mean HbA1c change from baseline for placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg was -  0.56%, -  0.91%, and -  0.78%, respectively (placebo-adjusted LS mean [95% CI] change: - 0.35% [-  0.72%, 0.02%]; -  0.22% [-  0.60%, 0.16%] for ertugliflozin 5 and 15 mg, respectively; p > 0.05 for both). In a post-hoc analysis that included Cohorts 1 and 2 (N = 292), the LS mean HbA1c change from baseline at week 18 for placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg was -  0.31%, - 0.77%, and -  0.68%, respectively (placebo-adjusted change: -  0.46% [-  0.73%, -  0.18%]; -  0.37% [-  0.66%, -  0.09%]; p = 0.001 and 0.01 for ertugliflozin 5 and 15 mg, respectively). In Cohort 1, adverse events were reported in 45.8%, 47.3%, and 25.9% of patients with placebo, ertugliflozin 5 mg, and ertugliflozin 15 mg. The incidence rates of symptomatic hypoglycemia were 0.0%, 5.5%, and 3.7%, respectively, with no cases of severe hypoglycemia. The safety profile was similar for Cohorts 1 and 2 combined.

CONCLUSION

The addition of ertugliflozin to SU monotherapy reduced HbA1c but did not result in significant placebo-adjusted reductions from baseline according to the prespecified primary analysis (n = 157); however, in a post-hoc analysis with a larger patient population (n = 292), significant and clinically relevant HbA1c reductions were observed. Ertugliflozin was generally well tolerated.
