Combination Therapy with an SGLT2 Inhibitor as Initial Treatment for Type 2 Diabetes: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Guidelines differ with regard to indications for initial combination pharmacotherapy for type 2 diabetes.

Aims

To compare the efficacy and safety of (i) sodium-glucose cotransporter 2 (SGLT2) inhibitor combination therapy in treatment-naïve type 2 diabetes adults; (ii) initial high and low dose SGLT2 inhibitor combination therapy.

Methods

PubMed, Embase and Cochrane Library were searched for randomised controlled trials (RCTs) of initial SGLT2 combination therapy. Mean difference (MD) for changes from baseline (HbA1c, weight, blood pressure) after 24?26 weeks of treatment and relative risks (RR, safety) were calculated using a random-effects model. Risk of bias and quality of evidence was assessed.

Results

In 4 RCTs (n = 3749) there was moderate quality evidence that SGLT2 inhibitor/metformin combination therapy resulted in a greater reduction in HbA1c (MD (95% CI); -0.55% (-0.67, -0.43)) and weight (-2.00 kg (-2.34, -1.66)) compared with metformin monotherapy, and a greater reduction in HbA1c (-0.59% (-0.72, -0.46)) and weight (-0.57 kg (-0.89, -0.25)) compared with SGLT2 inhibitor monotherapy. The high dose SGLT2 inhibitor/metformin combination resulted in a similar HbA1c but greater weight reduction; -0.47 kg (-0.88, -0.06) than the low dose combination therapy. The RR of genital infection with combination therapy was 2.22 (95% CI 1.33, 3.72) and 0.69 (95% CI 0.50, 0.96) compared with metformin and SGLT2 inhibitor monotherapy, respectively. The RR of diarrhoea was 2.23 (95% CI 1.46, 3.40) with combination therapy compared with SGLT2 inhibitor monotherapy.

Conclusions

Initial SGLT2 inhibitor/metformin combination therapy has glycaemic and weight benefits compared with either agent alone and appears relatively safe. High dose SGLT2 inhibitor/metformin combination therapy appears to have modest weight, but no glycaemic benefits compared with the low dose combination therapy.

Project description:IntroductionThe aim of this study was to evaluate the efficacy and safety of initial combination therapy compared with monotherapy in drug-naïve type 2 diabetes patients.MethodsMEDLINE, Embase and the Cochrane Central Register of Controlled Trials were searched for randomized clinical trials of initial combination therapy with hypoglycemic agents compared with monotherapy. Those which satisfied the search criteria were included in the meta-analysis. Weighted mean difference and relative risks were calculated.ResultsA total of 36 studies were included in the meta-analysis. Compared with metformin monotherapy, initial combination therapy with metformin plus another anti-diabetes drug exhibited significant reductions in glycated hemoglobin (HbA1c) (p < 0.001). Most of the combination therapies had a similar risk of hypoglycemia (p > 0.05), with the exception of combinations of sulfonylurea/glinide and metformin or combinations of thiazolidinedione and metformin. Compared with dipeptidyl peptidase-4 (DPP-4) inhibitor monotherapy, initial combination therapy with DPP-4 inhibitor plus another anti-diabetes drug showed a significant decrease in HbA1c (p < 0.001) and a similar risk of hypoglycemia (p > 0.05). Compared with monotherapy with other anti-diabetes drugs, initial combination therapies also resulted in significant HbA1c reductions, a similar risk of hypoglycemia and similar risks of other adverse events.ConclusionCompared with monotherapy, all initial combination therapies resulted in significant HbA1c reductions. Compared with metformin monotherapy, initial combination therapies with DPP-4 inhibitors plus metformin, sodium/glucose cotransporter 2 inhibitors and metformin, respectively, were associated with similar risks of hypoglycemia, but initial combination therapies with sulfonylurea plus metformin, thiazolidinedione and metformin, respectively, were associated with higher risks of hypoglycemia.FundingAstraZeneca Ltd.

Project description:BackgroundDespite 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.ObjectiveTo assess the clinical effectiveness and safety of the SGLT2 receptor inhibitors in dual or triple therapy in type 2 diabetes.Data sourcesMEDLINE, Embase, Cochrane Library (all sections); Science Citation Index; trial registries; conference abstracts; drug regulatory authorities; bibliographies of retrieved papers.Inclusion criteriaRandomised controlled trials of SGLT2 receptor inhibitors compared with placebo or active comparator in type 2 diabetes in dual or combination therapy.MethodsSystematic review. Quality assessment used the Cochrane risk of bias score.ResultsSeven 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).LimitationsLong-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.ConclusionsDapagliflozin appears effective in reducing HbA1c and weight in type 2 diabetes, although more safety data are needed.

Project description:IntroductionThe treatment of type 2 diabetes mellitus (T2DM) continues to pose challenges for clinicians and patients. The dramatic rise in T2DM prevalence, which has paralleled the rise in obesity, has strained the healthcare system and prompted the search for therapies that not only effectively treat hyperglycemia, but are also weight neutral or promote weight loss. In most clinical situations after diagnosis, patients are advised to adopt lifestyle changes and metformin is initiated to help control blood glucose levels. However, metformin may not be tolerated, or may not be sufficient for those with higher glucose levels at diagnosis. Even among those who have initial success with metformin, the majority eventually require one or more additional agents to achieve their treatment goals. Because T2DM is a progressive disease, the requirement for combination treatment escalates over time, driving the need for therapies with complementary mechanisms of action.Methods and resultsOnline public resources were searched using "empagliflozin", identifying 32 articles in PubMed, and 12 abstracts presented at the 2013 American Diabetes Association meeting. Peer-reviewed articles and abstracts describing preclinical studies and clinical trials were retrieved, and relevant publications included in this review. Trials registered on clinicaltrials.gov were searched for ongoing empagliflozin studies.ConclusionThe sodium-glucose co-transporter 2 (SGLT2) inhibitors are of great interest since they provide a novel, insulin-independent mechanism of action. The SGLT2 inhibitor empagliflozin has demonstrated promising pharmacodynamic and pharmacokinetic properties. In clinical trials, empagliflozin has demonstrated a good efficacy and safety profile in a broad range of patients with T2DM, and appears to be an attractive adjunct therapeutic option for the treatment of T2DM. Ongoing trials, including patients with T2DM and comorbidities such as hypertension, are expected to provide important additional data, which will further define the role of empagliflozin in a growing movement toward individualized approaches to diabetes care.
