Objective: The cardiorenal benefits of adding sodium-glucose cotransporter 2 (SGLT2) inhibitor therapy for patients on insulin, particularly those on intensive regimens that include short-acting (SA) insulin, have not been explored.Research Design and Methods: In Dapagliflozin Effect on Cardiovascular Events trial (DECLARE-TIMI 58), 17,160 patients with type 2 diabetes were randomized to dapagliflozin or placebo for a median follow-up of 4.2 years. Cardiovascular (CV), renal, metabolic, and safety outcomes with dapagliflozin versus placebo by insulin dose and regimen were studied with Cox regression models.Results: The study included 7,013 insulin users at baseline, with 4,650 (66.3%) patients on regimens including SA insulin. Insulin doses varied, with 2,443 (34.8%) patients receiving <0.5 IU/kg, 2,795 (39.9%) 0.5 to ≤1 IU/kg, and 1,339 (19.1%) >1 IU/kg. Dapagliflozin reduced CV death/hospitalization for heart failure among overall insulin users (hazard ratio [HR] 0.82 [95% CI 0.69-0.97]) and consistently in patients on insulin regimens with or without SA insulin (0.83 [0.67-1.03] and 0.78 [0.57-1.07], respectively, Pinteraction = 0.75). No heterogeneity was observed by insulin dose (Pinteraction = 0.43). The HR for major adverse CV events with dapagliflozin among insulin users (0.84 [0.74-0.97]) was similar irrespective of regimen or dose (Pinteraction = 0.75 and 0.07). Dapagliflozin reduced the rate of adverse renal outcomes overall and consistently across subgroups of insulin users. Decreases in HbA1c, weight, and systolic blood pressure with dapagliflozin were seen regardless of insulin dose or regimen. The known safety profile of dapagliflozin was unchanged in patients on intensive insulin regimens.Conclusions: The benefits and safety of dapagliflozin were maintained in high-risk patients receiving high-dose or intensive insulin regimens including SA insulin.Article Highlights: Limited data exist regarding the cardiorenal, metabolic, and safety outcomes of SGLT2 inhibitors in patients on high-dose or intensive insulin regimens including short-acting insulin. In DECLARE-TIMI 58, 17,160 patients including 7,013 baseline insulin users were randomized to dapagliflozin versus placebo. Outcomes among insulin users by insulin dose and regimen were studied. Our results suggest that use of dapagliflozin by patients with type 2 diabetes managed with insulin, including high-dose or intensive insulin regimens, provided significant cardiovascular, renal, and metabolic benefits, in line with overall trial results. Adverse events associated with dapagliflozin, including hypoglycemia and diabetic ketoacidosis, were rare in this cohort. [ABSTRACT FROM AUTHOR]

Objective: Sodium-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 Methods: DECLARE-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.Results: Baseline 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, Pinteraction = 0.033), and the renal-specific outcome was reduced for all UACR subgroups (P < 0.05, Pinteraction = 0.480).Conclusions: In 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. [ABSTRACT FROM AUTHOR]

Objective: International guidelines propose prescribing sodium-glucose cotransporter 2 (SGLT2) inhibitors to patients with type 2 diabetes (T2D) as secondary prevention in patients with established atherosclerotic cardiovascular disease (ASCVD) or for primary prevention of cardiovascular events in high-risk patients with multiple risk factors (MRF) for ASCVD. The current analyses expand on the cardiovascular renal and metabolic effects of SGLT2 inhibitors in MRF patients.Research Design and Methods: In DECLARE-TIMI 58, 17,160 patients with T2D and MRF (59.4%) or established ASCVD (40.6%) were randomized to dapagliflozin versus placebo; patients were followed for a median of 4.2 years. The cardiovascular and renal outcomes in the MRF cohort were studied across clinically relevant subgroups for treatment effect and subgroup-based treatment interaction.Results: Among patients with MRF, the reduction with dapagliflozin in risk of cardiovascular death or hospitalization for heart failure (CVD/HHF) (hazard ratio [HR] 0.84, 95% CI 0.67-1.04) and the renal-specific outcome (HR 0.51, 95% CI 0.37-0.69) did not differ from that for patients with ASCVD (Pinteraction 0.99 and 0.72, respectively). The effect on CVD/HHF was entirely driven by a reduction in HHF (HR 0.64, 95% CI 0.46-0.88). The benefits of dapagliflozin on HHF and on the renal-specific outcome, among the subset with MRF, were directionally consistent across clinically relevant subgroups. At 48 months, HbA1c, weight, systolic blood pressure, and urinary albumin-to-creatinine ratio were lower with dapagliflozin versus placebo and estimated glomerular filtration rate was higher (P < 0.001).Conclusions: In patients with T2D and MRF, dapagliflozin reduced the risk of HHF and adverse renal outcomes regardless of baseline characteristics. These analyses support the benefit of dapagliflozin for important outcomes in a broad primary prevention population. [ABSTRACT FROM AUTHOR]

Aim: To assess the associations between baseline glucose‐lowering agents (GLAs) and cardiorenal outcomes with dapagliflozin versus placebo in the DECLARE‐TIMI 58 study. Materials and methods: DECLARE‐TIMI 58 assessed the cardiorenal outcomes of dapagliflozin versus placebo in patients with type 2 diabetes. This post hoc analysis elaborates the efficacy and safety outcomes by baseline GLA for treatment effect and GLA‐based treatment interaction. Results: At baseline, 14 068 patients (82.0%) used metformin, 7322 (42.7%) sulphonylureas, 2888 (16.8%) dipeptidyl peptidase‐4 inhibitors, 750 (4.4%) glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) and 7013 (40.9%) insulin. Dapagliflozin reduced the composite of cardiovascular death (CVD) and hospitalization for heart failure (HHF) versus placebo regardless of baseline GLA, with greater benefit in the small group of patients with baseline use of GLP‐1 RAs (HR [95% CI] 0.37 [0.18, 0.78] vs. 0.86 [0.75, 0.98] in GLP‐1 RA users vs. non‐users, Pinteraction =.03). The overall HR for major adverse cardiovascular events (CVD, myocardial infarction or ischaemic stroke) was 0.93 (95% CI 0.84, 1.03) with dapagliflozin versus placebo, with no interaction by baseline GLA (Pinteraction >.05). The renal‐specific outcome was reduced with dapagliflozin versus placebo in the overall cohort (HR [95%CI] 0.53[0.43‐0.66]), with no interaction by baseline GLA (Pinteraction >.05). All of these outcomes were similar in those with versus those without baseline metformin use. Conclusions: The effects of dapagliflozin on cardiorenal outcomes were generally consistent regardless of baseline GLA, with consistent benefits regardless of baseline metformin use. The potential clinical benefit of combining sodium‐glucose co‐transporter‐2 inhibitors with GLP‐1 RAs, given some evidence of cardiovascular risk reduction with both classes, should be explored further.

Aims: To evaluate comprehensively the safety of dapagliflozin in patients with type 2 diabetes (T2DM), with emphasis placed on potential safety concerns related to the sodium‐glucose co‐transporter‐2 inhibitor class. Methods: In the Dapagliflozin Effect on Cardiovascular Events – Thrombolysis in Myocardial Infarction 58 (DECLARE‐TIMI 58) study, 17 160 patients with T2DM were randomized to dapagliflozin or placebo and followed for a median of 4.2 years. Safety was evaluated in 17 143 patients receiving at least one dose of study drug. Results: Acute kidney injury occurred less frequently with dapagliflozin, and adverse events suggestive of volume depletion were balanced between treatment groups, both irrespective of baseline estimated glomerular filtration rate, blood pressure, diuretic or loop diuretic use (interaction P values >0.05). Fractures and malignancies were balanced between the groups, irrespective of sex, diabetes duration or smoking (interaction P values >0.05) and fewer cases of bladder cancer occurred in the dapagliflozin versus the placebo group. Diabetic ketoacidosis was very rare, but more frequent with dapagliflozin versus placebo (27 vs. 12 patients with events; P = 0.02), yet signs, symptoms and contributing factors were similar in the two groups. Major hypoglycaemia occurred less frequently with dapagliflozin versus placebo, regardless of baseline use of either insulin or sulphonylureas (interaction P values >0.05). There were more adverse events of genital infections leading to discontinuation of study drug in the dapagliflozin versus the placebo group, but serious genital infections were few and balanced between treatment groups. Urinary tract infections, acute pyelonephritis and urosepsis were also balanced between treatment groups. Conclusions: Dapagliflozin was well tolerated. The long duration and large number of patient‐years in DECLARE‐TIMI 58 comprehensively addressed previous safety questions, confirming the robust safety profile of dapagliflozin.

Aim: To investigate whether the cardiovascular and renal benefits observed with dapagliflozin in the DECLARE‐TIMI 58 trial are also observed in patients with short and long‐standing diabetes. Materials and Methods: This post hoc analysis studied the dual primary efficacy endpoints, a composite of cardiovascular death or hospitalization for heart failure (CVD/HHF) and major adverse cardiovascular events (MACE; CVD, myocardial infarction [MI], ischaemic stroke) by diabetes duration. Results: Of the 17 160 patients, 3836 had diabetes duration of ≤5 years, 4731 >5‐10 years, 3952 >10‐15 years, 2433 >15‐20 years and 2206 >20 years. Dapagliflozin reduced the risk of CVD/HHF by a similar amount across diabetes duration subgroups, ranging from HR 0.79 (0.58‐1.06) in patients with diabetes duration of ≤5 years to 0.75 (0.55‐1.03) in those patients with diabetes duration of >20 years (interaction trend P‐value 0.76). Hazard ratios (HRs) for MACE ranged from 1.08 (0.87‐1.35) in patients with diabetes duration of ≤5 years to 0.67 (0.52‐0.86) in those patients with diabetes duration of >20 years (interaction trend P‐value 0.004). This was driven by greater reductions in the risk of MI and ischaemic stroke with dapagliflozin in patients with long‐standing diabetes (interaction trend P‐values 0.019 and 0.015, respectively). The duration‐based MACE heterogeneity was apparent in those with or without a history of prior MI and in those with multiple risk factors. The renal‐specific outcome was reduced with dapagliflozin with HRs ranging from 0.79 (0.47‐1.34) in patients with diabetes duration of ≤5 years to 0.42 (0.25‐0.72) in those patients with diabetes duration of >20 years (interaction trend P‐value 0.084). Conclusions: Dapagliflozin reduced the risk of CVD/HHF consistently, regardless of diabetes duration, whereas the treatment effect for MACE differed by duration subgroups, with significant reductions with dapagliflozin in patients with long‐standing diabetes.

Objective: Data regarding the effects of sodium-glucose cotransporter 2 inhibitors in the elderly (age ≥65 years) and very elderly (age ≥75 years) are limited.Research Design and Methods: The Dapagliflozin Effect on Cardiovascular Events (DECLARE)-TIMI 58 assessed cardiac and renal outcomes of dapagliflozin versus placebo in patients with type 2 diabetes. Efficacy and safety outcomes were studied within age subgroups for treatment effect and age-based treatment interaction.Results: Of the 17,160 patients, 9,253 were <65 years of age, 6,811 ≥65 to <75 years, and 1,096 ≥75 years. Dapagliflozin reduced the composite of cardiovascular death or hospitalization for heart failure consistently, with a hazard ratio (HR) of 0.88 (95% CI 0.72, 1.07), 0.77 (0.63, 0.94), and 0.94 (0.65, 1.36) in age-groups <65, ≥65 to <75, and ≥75 years, respectively (interaction P value 0.5277). Overall, dapagliflozin did not significantly decrease the rates of major adverse cardiovascular events, with HR 0.93 (95% CI 0.81, 1.08), 0.97 (0.83, 1.13), and 0.84 (0.61, 1.15) in age-groups <65, ≥65 to <75, and ≥75 years, respectively (interaction P value 0.7352). The relative risk reduction for the secondary prespecified cardiorenal composite outcome ranged from 18% to 28% in the different age-groups with no heterogeneity. Major hypoglycemia was less frequent with dapagliflozin versus placebo, with HR 0.97 (95% CI 0.58, 1.64), 0.50 (0.29, 0.84), and 0.68 (0.29, 1.57) in age-groups <65, ≥65 to <75, and ≥75 years, respectively (interaction P value 0.2107). Safety outcomes, including fractures, volume depletion, cancer, urinary tract infections, and amputations were balanced with dapagliflozin versus placebo, and acute kidney injury was reduced, all regardless of age. Genital infections that were serious or led to discontinuation of the study drug and diabetic ketoacidosis were uncommon, yet more frequent with dapagliflozin versus placebo, without heterogeneity (interaction P values 0.1058 and 0.8433, respectively).Conclusions: The overall efficacy and safety of dapagliflozin are consistent regardless of age.
