Use and effectiveness of dapagliflozin in patients with type 2 diabetes mellitus: a multicenter retrospective study in Taiwan.

ABSTRACT: Aims/Introduction:To investigate the clinical outcomes of patients with type 2 diabetes mellitus (T2DM) who initiated dapagliflozin in real-world practice in Taiwan. Materials and Methods:In this multicenter retrospective study, adult patients with T2DM who initiated dapagliflozin after May 1st 2016 either as add-on or switch therapy were included. Changes in clinical and laboratory parameters were evaluated at 3 and 6 months. Baseline factors associated with dapagliflozin response in glycated hemoglobin (HbA1c) were analyzed by univariate and multivariate logistic regression. Results:A total of 1,960 patients were eligible. At 6 months, significant changes were observed: HbA1c by -0.73% (95% confidence interval [CI] -0.80, -0.67), body weight was -1.61 kg (95% CI -1.79, -1.42), and systolic/diastolic blood pressure by -3.6/-1.4 mmHg. Add-on dapagliflozin showed significantly greater HbA1c reduction (-0.82%) than switched therapy (-0.66%) (p = 0.002). The proportion of patients achieving HbA1c <7% target increased from 6% at baseline to 19% at Month 6. Almost 80% of patients experienced at least 1% reduction in HbA1c, and 65% of patients showed both weight loss and reduction in HbA1c. Around 37% of patients had at least 3% weight loss. Multivariate logistic regression analysis indicated patients with higher baseline HbA1c and those who initiated dapagliflozin as add-on therapy were associated with a greater reduction in HbA1c. Conclusions:In this real-world study with the highest patient number of Chinese population to date, the use of dapagliflozin was associated with significant improvement in glycemic control, body weight, and blood pressure in patients with T2DM. Initiating dapagliflozin as add-on therapy showed better glycemic control than as switch therapy.

Project description:IntroductionTo date there is a lack of economic analysis comparing glucagon-like peptide-1 receptor agonists (GLP-1RAs) to sodium-glucose co-transporter 2 inhibitors (SGLT-2i) for the treatment of type 2 diabetes mellitus (T2DM). Liraglutide and dapagliflozin are the most commonly prescribed GLP-1RA and SGLT-2i in the UK. This analysis investigated the cost-effectiveness of liraglutide 1.2 and 1.8 mg/day compared to dapagliflozin 10 mg/day for the treatment of T2DM in the UK in patients on dual and triple antidiabetic therapy.MethodsCost-effectiveness analysis was conducted in the QuintilesIMS CORE Diabetes Model (CDM). The model estimated expected costs and outcomes over a lifetime horizon using the UK national payer perspective. Liraglutide efficacy estimates and patient characteristics were sourced from a trial in patients on prior metformin monotherapy, and from a trial in patients on prior combination therapy. Comparative efficacy data for the other interventions were derived from a network meta-analysis. Utility inputs were extracted from a systematic literature review. Costs are presented in Great British Pound (GBP), 2016 values.ResultsIn dual and triple therapy, liraglutide 1.2 mg was less costly and more effective compared with dapagliflozin 10 mg, providing a QALY gain of 0.04 and cost savings of GBP 11 per patient in dual therapy, and a QALY gain of 0.06 and cost savings of GBP 71 per patient in triple therapy. For liraglutide 1.8 mg, increased efficacy and costs compared with dapagliflozin 10 mg were observed in both dual and triple therapy. In dual therapy, a QALY gain of 0.07 and additional costs of GBP 888 per patient yielded an ICER of GBP 13,227, whereas in triple therapy a QALY gain of 0.07 and additional cost of GBP 791 per patient gave an ICER of 11,857.ConclusionThis long-term modelling analysis found that both dosages of liraglutide may be cost-effective treatment alternatives as part of a dual or a triple antidiabetic therapy in patients for whom an SGLT-2i therapy is considered.FundingNovo Nordisk.

Project description:Recent studies reported that sodium glucose cotransporter 2 (SGLT2) inhibitors can potentially reduce the risk of cardiovascular mortality in patients with type 2 diabetes mellitus (T2DM). However, there is little or no information on the therapeutic effects of SGLT2 inhibitors on the progression of atherosclerosis. This dapagliflozin effectiveness on vascular endothelial function and glycemic control (DEFENCE) study was designed to determine the effects of dapagliflozin, a SGLT2 inhibitor, on endothelial function in patients with early-stage T2DM.DEFENCE is a prospective, randomized, open-label, blinded-endpoint, parallel-group, comparative clinical trial. Between October 2015 and August 2016, 80 T2DM patients treated with 750 mg of metformin (hemoglobin A1c ?6.0 and <8.0%, n = 80) were enrolled and randomized to receive either 1500 mg/day metformin (the metformin group, n = 40), or 750 mg/day metformin supplemented with 5 mg/day dapagliflozin (the dapagliflozin group, n = 40), for 16 weeks. The primary endpoint was a change in flow-mediated dilation (FMD) from baseline to the end of the 16-week treatment period. The secondary outcomes include changes in indexes of glycemic control, lipid metabolism, and oxidative stress, body composition, and safety evaluation.Although FMD tended to improve only in the dapagliflozin group, ?FMD was comparable between the two groups. Analysis of patients with HbA1c >7.0% showed significant improvement of FMD in the dapagliflozin group than metformin group (P < 0.05). HbA1c, fasting plasma glucose, plasma glucagon, and body weight significantly decreased in both groups. Interestingly, urine 8-hydroxy-2'-deoxyguanosin, a biomarker of oxidative stress, was significantly lower in the dapagliflozin group than metformin group at 16 weeks (P < 0.001).Dapagliflozin add-on therapy to metformin for 16 weeks improved endothelial function, as assessed by FMD, in patients with inadequately controlled early-stage T2DM. Improvement in oxidative stress may contribute to the improvement in FMD. Trial registration University Hospital Medical Information Network Clinical Trial Registry (UMIN000018754).
