Dapagliflozin vs non-SGLT-2i treatment is associated with lower healthcare costs in type 2 diabetes patients similar to participants in the DECLARE-TIMI 58 trial: A nationwide observational study.

ABSTRACT: AIMS:To investigate how the cardiovascular (CV) risk benefits of dapagliflozin translate into healthcare costs compared with other non-sodium-glucose cotransporter-2 inhibitor glucose-lowering drugs (oGLDs) in a real-world population with type 2 diabetes (T2D) that is similar to the population of the DECLARE-TIMI 58 trial. METHODS:Patients initiating dapagliflozin or oGLDs between 2013 and 2016 in Swedish nationwide healthcare registries were included if they fulfilled inclusion and exclusion criteria of the DECLARE-TIMI 58 trial (DECLARE-like population). Propensity scores for the likelihood of dapagliflozin initiation were calculated, followed by 1:3 matching with initiators of oGLDs. Per-patient cumulative costs for hospital healthcare (in- and outpatient) and for drugs were calculated from new initiation until end of follow-up. RESULTS:A total of 24?828 patients initiated a new GLD; 6207 initiated dapagliflozin and 18?621 initiated an oGLD. After matching based on 96 clinical and healthcare cost variables, groups were balanced at baseline. Mean cumulative 30-month healthcare cost per patient was similar in the dapagliflozin and oGLD groups ($11?807 and $11?906, respectively; difference, -$99; 95% CI, -$629, $483; P = 0.644). Initiation of dapagliflozin rather than an oGLD was associated with significantly lower hospital costs (-$658; 95% CI, -$1169, -$108; P = 0.024) and significantly higher drug costs ($559; 95% CI, $471, $648; P?

Project description:ObjectiveSodium-glucose cotransporter 2 inhibitors (SGLT2i) improve albuminuria in patients with high cardiorenal risk. We report albuminuria change in the Dapagliflozin Effect on Cardiovascular Events (DECLARE-TIMI 58) cardiovascular outcome trial, which included populations with lower cardiorenal risk.Research design and methodsDECLARE-TIMI 58 randomized 17,160 patients with type 2 diabetes, creatinine clearance >60 mL/min, and either atherosclerotic cardiovascular disease (CVD; 40.6%) or risk-factors for CVD (59.4%) to dapagliflozin or placebo. Urinary albumin-to-creatinine ratio (UACR) was tested at baseline, 6 months, 12 months, and yearly thereafter. The change in UACR over time was measured as a continuous and categorical variable (≤15, >15 to <30, ≥30 to ≤300, and >300 mg/g) by treatment arm. The composite cardiorenal outcome was a ≥40% sustained decline in the estimated glomerular filtration rate (eGFR) to <60 mL/min/1.73 m2, end-stage kidney disease, and cardiovascular or renal death; specific renal outcome included all except cardiovascular death.ResultsBaseline UACR was available for 16,843 (98.15%) participants: 9,067 (53.83%) with ≤15 mg/g, 2,577 (15.30%) with >15 to <30 mg/g, 4,030 (23.93%) with 30-300 mg/g, and 1,169 (6.94%) with >300 mg/g. Measured as a continuous variable, UACR improved from baseline to 4.0 years with dapagliflozin, compared with placebo, across all UACR and eGFR categories (all P < 0.0001). Sustained confirmed ≥1 category improvement in UACR was more common in dapagliflozin versus placebo (hazard ratio 1.45 [95% CI 1.35-1.56], P < 0.0001). Cardiorenal outcome was reduced with dapagliflozin for subgroups of UACR ≥30 mg/g (P < 0.0125, P interaction = 0.033), and the renal-specific outcome was reduced for all UACR subgroups (P < 0.05, P interaction = 0.480).ConclusionsIn DECLARE-TIMI 58, dapagliflozin demonstrated a favorable effect on UACR and renal-specific outcome across baseline UACR categories, including patients with normal albumin excretion. The results suggest a role for SGLT2i also in the primary prevention of diabetic kidney disease.

Project description:AimsTo investigate cardiovascular (CV) safety and event rates for dapagliflozin versus other glucose-lowering drugs (GLDs) in a real-world type 2 diabetes population after applying the main inclusion criteria and outcomes from the DECLARE-TIMI 58 study.MethodsPatients with new initiation of dapagliflozin and/or other GLDs were identified in Swedish nationwide healthcare registries for the period 2013 to 2016. Patients were included if they met the main DECLARE-TIMI 58 inclusion criteria: age ≥40 years and established CV disease or presence of multiple-risk factors, e.g. men aged ≥55 years and women aged ≥60 years with hypertension or dyslipidaemia. Propensity scores for the likelihood of dapagliflozin initiation were calculated, then 1:3 matching was carried out. DECLARE-TIMI 58 outcomes were hospitalization for heart failure (HHF) or CV-specific mortality, and major adverse CV events (MACE; CV-specific mortality, myocardial infarction, or stroke). Cox survival models were used to estimate hazard ratios (HRs).ResultsAfter matching, a total of 28 408 new-users of dapagliflozin and/or other GLDs were identified, forming the population for the present study (henceforth referred to as the DECLARE-like cohort. The mean age of this cohort was 66 years, and 34% had established CV disease. Dapagliflozin was associated with 21% lower risk of HHF or CV mortality versus other GLDs (HR 0.79, 95% confidence interval [CI] 0.69-0.92) and had no significant association with MACE (HR 0.90, 95% CI 0.79-1.03). HHF and CV mortality risks, separately, were lower at HR 0.79 (95% CI 0.67-0.93) and HR 0.75 (95% CI 0.57-0.97), respectively. Non-significant associations were seen for myocardial infarction and stroke: HR 0.91 (95% CI 0.74-1.11) and HR 1.06 (95% CI 0.87-1.30), respectively.ConclusionIn a real-world population similar to those included in the DECLARE-TIMI 58 study, dapagliflozin was safe with regard to CV outcomes and resulted in lower event rates of HHF and CV mortality versus other GLDs.

Project description:IntroductionSince 2008 United State (US) food drug administration mandate, several newer anti-diabetic drugs (ADD) have undergone a mandatory cardiovascular (CV) outcome trial (CVOT) in type diabetes (T2DM) patients with high CV risk. These includes CVOT done with dipeptidyl-peptidase-4 inhibitors, sodium-glucose co-transporter-2 inhibitors and glucagon-like peptide-1 receptor agonist (GLP-1RAs). Several double-blind, randomized, placebo-controlled CVOT have been presented and published in the last decade (2008-2018).Aims and objectivesWe systematically searched the database of PubMed and ClinicalTrials.gov from January 1, 2008 to December 31, 2018 using specific key words. Subsequently, we pooled the data of different cardiovascular endpoints and made a comparative forest plot using GraphPad software Inc. Prism Version 8, US.Results and conclusionSaxagliptin, alogliptin, sitagliptin and linagliptin are CV neutral drugs. Saxagliptin showed a significantly higher hospitalization due to heart failure (HHF). Empagliflozin and canagliflozin have shown a significant reduction in composite of 3-point major cardiac adverse events (3P-MACE). Additionally, empagliflozin, canagliflozin and dapagliflozin significantly reduced the HHF and the composite of CV death or HHF. Moreover, empagliflozin showed significant reduction in CV- and all-cause death in patients with T2DM with established CV disease. While both exendin-backbone-based GLP-1RAs such as lixisenatide and extended-release exenatide were CV neutral; GLP-1-backbone-based GLP-1RAs such as liraglutide, semaglutide and albiglutide shown a significant reduction in the composite of 3-P MACE. Additionally, liraglutide shown a significant reduction in CV- and all-cause death. Moreover, semaglutide reduced non-fatal stroke and albiglutide reduced myocardial infarction, while extended-release exenatide reduced all-cause death; however, P value of significance for these outcomes should be considered nominal.

Project description:BACKGROUND AND AIMS:Sodium tissue content by 23Na magnetic resonance imaging (Na-MRI) has been validated in experimental and human studies. SGLT-2 inhibition blocks the reabsorption of glucose and of sodium in the proximal tubular cells in a 1:1 fashion. We hypothesized that SGLT-2 inhibition in patients with type 2 diabetes characterized by sodium retention leads to decreased tissue sodium content due to its pharmacological action. MATERIALS AND METHODS:In a prospective double blind, placebo controlled, cross-over trial 59 patients (61 ± 7.6 years) with type 2 diabetes were randomized to either dapagliflozin 10 mg or placebo once daily for 6 weeks each. In addition to metabolic parameters and ambulatory blood pressure (BP) we analysed the sodium content in the skin and muscles of the lower leg by Na-MRI. RESULTS:Compared to baseline 6 weeks treatment with the SGLT-2 inhibitor dapagliflozin decreased fasting (132 ± 28 vs. 114 ± 19 mg/dl, p < 0.001), postprandial blood glucose (178 ± 66 mg/dl vs. 153 ± 46 mg/dl, p < 0.001), body weight (87.6 vs. 86.6 kg, p < 0.001) and systolic (129 ± 12 vs. 126 ± 11 mmHg, p = 0.010), and diastolic (77.4 ± 9 vs. 75.6 ± 8 mmHg, p = 0.024), 24-h ambulatory BP. Tissue sodium content in the skin was reduced after 6 weeks treatment with dapagliflozin compared to baseline [24.1 ± 6.6 vs. 22.7 ± 6.4 A.U.(arbitrary unit) p = 0.013]. No significant reduction of tissue sodium content was observed in the muscle (M. triceps surae: 20.5 ± 3.5 vs. 20.4 ± 3.7 A.U. p = 0.801). No clear significant difference in tissue water content of muscle and skin was observed after 6 weeks of treatment with dapagliflozin, compared to baseline. CONCLUSION:SGLT-2 inhibition with dapagliflozin resulted in a significant decrease in tissue sodium content of the skin after 6 weeks. This observation point to a decrease of total sodium content in patients with type 2 diabetes prone to cardiovascular complications, that might be mitigated by SGLT-2 inhibition.
