Systematic review of SGLT2 receptor inhibitors in dual or triple therapy in type 2 diabetes.

ABSTRACT:

Background

Despite the number of medications for type 2 diabetes, many people with the condition do not achieve good glycaemic control. Some existing glucose-lowering agents have adverse effects such as weight gain or hypoglycaemia. Type 2 diabetes tends to be a progressive disease, and most patients require treatment with combinations of glucose-lowering agents. The sodium glucose co-transporter 2 (SGLT2) receptor inhibitors are a new class of glucose-lowering agents.

Objective

To assess the clinical effectiveness and safety of the SGLT2 receptor inhibitors in dual or triple therapy in type 2 diabetes.

Data sources

MEDLINE, Embase, Cochrane Library (all sections); Science Citation Index; trial registries; conference abstracts; drug regulatory authorities; bibliographies of retrieved papers.

Inclusion criteria

Randomised controlled trials of SGLT2 receptor inhibitors compared with placebo or active comparator in type 2 diabetes in dual or combination therapy.

Methods

Systematic review. Quality assessment used the Cochrane risk of bias score.

Results

Seven trials, published in full, assessed dapagliflozin and one assessed canagliflozin. Trial quality appeared good. Dapagliflozin 10 mg reduced HbA1c by -0.54% (weighted mean differences (WMD), 95% CI -0.67 to -0.40) compared to placebo, but there was no difference compared to glipizide. Canagliflozin reduced HbA1c slightly more than sitagliptin (up to -0.21% vs sitagliptin). Both dapagliflozin and canagliflozin led to weight loss (dapagliflozin WMD -1.81 kg (95% CI -2.04 to -1.57), canagliflozin up to -2.3 kg compared to placebo).

Limitations

Long-term trial extensions suggested that effects were maintained over time. Data on canagliflozin are currently available from only one paper. Costs of the drugs are not known so cost-effectiveness cannot be assessed. More data on safety are needed, with the Food and Drug Administration having concerns about breast and bladder cancers.

Conclusions

Dapagliflozin appears effective in reducing HbA1c and weight in type 2 diabetes, although more safety data are needed.

Project description:BackgroundType 2 diabetes is closely related to an increased risk of atrial fibrillation (AF) and atrial flutter (AFL). Whether sodium-glucose cotransporter 2 (SGLT2) inhibitors can attenuate AF/AFL progression remains unclear.MethodsWe searched electronic databases (PubMed, Embase and ClinicalTrials.gov) from their inception to January 2020 for trials evaluating the AF outcomes of SGLT2 inhibitors in patients with type 2 diabetes. The data search and extraction were conducted with a standardized data form and any conflicts were resolved by consensus. Relative risks (RRs) with 95% confidence intervals (CIs) were used for binary variables, and the weighed mean differences (WMDs) with the standard deviation (SDs) were applied for continuous variables.ResultsWe included data from 16 identified trials consisting of 38,335 patients with type 2 diabetes. Incorporated data demonstrated that compared to placebo, SGLT2 inhibitors significantly reduced AF/AFL (RR: 0.76; 95% CI 0.65-0.90; p = 0.001) and all-cause mortality (RR: 0.91; 95% CI 0.83-0.99; p = 0.03). AF/AFL reductions were not modified by age, body weight, glycated haemoglobin (HbA1c), or systolic blood pressure (SBP) at baseline (all p-interactions > 0.3). SGLT2 inhibitors also significantly reduced heart failure events (RR: 0.73; 95% CI 0.64-0.84; p < 0.00001), HbA1c (WMD: - 0.62%; 95% CI - 0.89 to - 0.34; p < 0.00001), body weight (WMD: - 2.12 kg; 95% CI - 2.91 to - 1.34; p < 0.00001), SBP (WMD: - 3.34 mmHg; 95% CI - 4.12 to - 2.56; p < 0.00001), and diastolic blood pressure (DBP) (WMD: - 1.11 mmHg; 95% CI - 1.62 to - 0.60; p < 0.0001). Of note, cerebrovascular events and myocardial infarction did not increase in patients taking SGLT2 inhibitors.ConclusionSGLT2 inhibitors may confer a specific AF/AFL-reduction benefit in the susceptible type 2 diabetes population, regardless of age, body weight, HbA1c, and systolic blood pressure at baseline. Such an AF/AFL-reduction benefit may be partly attributed to pharmacological effects on reductions in HbA1c, body weight, blood pressure, and the occurrence of heart failure.
