#150 Effect of dapagliflozin in patients with CKD depending on primary kidney disease

Abstract Background and Aims Multiple trials have reported that SGLT2 inhibitors reduce the risk of its primary composite outcome of kidney disease progression or cardiovascular death in a wide range of patients with CKD. Our aim was to compare effects on kidney outcomes among the different types of kidney diseases. Method Eligible patients with eGFRs ≥30-45, or ≥45-90 ml/min/1.73 m2 with a urinary albumin-to-creatinine ratio of ≥300 mg/g, and receiving renin angiotensin system inhibitor, where indicated and tolerated were randomized to dapagliflozin 10 mg once daily vs placebo. Kidney disease progression was defined as a sustained ≥30% eGFR decline from randomization or to <10 mL/min/1.73 m2, start of maintenance dialysis or receipt of a kidney transplant, or renal death, and the effects of dapagliflozin were analyzed using a pre-specified Cox model. Testing for heterogeneity of effect between pre-specified kidney disease subgroups was performed, including exploratory analyses by specific glomerular disease etiologies. Results 362 participants were followed for a median of 2.0 years. 90 (24.8%) had diabetic kidney disease, 126 (34.8%) had glomerular disease, 94 (26%) had hypertensive or renovascular disease, and 52 (14.4%) had other or unknown causes. Overall, dapagliflozin reduced the risk of kidney disease progression by 34% (dapagliflozin 29/178 vs placebo 48/184; hazard ratio 0.62, 95% CI 0.51-0.78). This relative risk reduction appeared broadly similar in subgroup analyses by primary cause of kidney disease and by different types of glomerular disease. Conclusion Our study with a few numbers of patients with diabetic and non-diabetic causes of CKD showed that dapagliflozin reduced risk of kidney disease progression with relative risk reductions that were broadly similar across the different CKD etiologies.

Effect of dapagliflozin in patients with diabetes and heart failure with mildly reduced or preserved ejection fraction according to background glucose-lowering therapy: A pre-specified analysis of the DELIVER trial.

Type 2 diabetes (T2D) and heart failure (HF) frequently coexist, but whether clinical outcomes and treatment effects of sodium-glucose cotransporter 2 inhibitors (SGLT2i) vary in relation to background glucose-lowering therapy (GLT) in this population is uncertain. DELIVER randomized patients with HF and left ventricular ejection fraction (LVEF) >40% to dapagliflozin or placebo. The primary outcome was a composite of worsening HF (HF hospitalization or urgent HF visit) or cardiovascular death. In this pre-specified analysis of participants with T2D, treatment effects were assessed by number and class of background GLT(s). Of 3150 participants with T2D at baseline, 22.9% were on no GLT, 36.5% were treated with 1 GLT, and 40.6% with ≥2 GLTs. During follow-up (median: 2.3 years), treatment benefits of dapagliflozin (vs. placebo) on the primary outcome were consistent irrespective of the number of background GLTs (0 GLTs: hazard ratio [HR] 0.71, 95% confidence interval [CI] 0.50-1.00; 1 GLT: HR 1.04, 95% CI 0.80-1.34; ≥2 GLTs: HR 0.71, 95% CI 0.56-0.90; pinteraction = 0.59). Similar findings were observed among participants with (HR 0.73, 95% CI 0.59-0.92) and without background metformin use (HR 0.89, 95% CI 0.72-1.11; pinteraction = 0.22) and in participants with (HR 0.89, 95% CI 0.69-1.16) and without background insulin use (HR 0.78, 95% CI 0.65-0.95; pinteraction = 0.45). Dapagliflozin was well-tolerated irrespective of the number of background GLTs. Dapagliflozin safely and consistently improved clinical outcomes among individuals with T2D and HF with LVEF >40% irrespective of the number and class of background GLTs, and the benefits were not influenced by concomitant metformin or insulin use. These data bolster contemporary guidelines supporting first-line SGLT2i among individuals with T2D and HF, irrespective of background GLT.

The association of rs4646994 ACE and rs1799983 eNOS gene polymorphisms with metabolic effects of dapagliflozin in patients with diabetic nephropathy and essential hypertension

Objective — to establish possible associations of rs4646994 ACE and rs1799983 eNOS gene polymorphisms with metabolic effects of dapagliflozin in patients (pts) with diabetic nephropathy (DN) and essential hypertension (EH).
 Materials and methods. Clinical investigation and examinations involved 171 pts, from them 85 (49.7%) females and 86 (50.3%) males with DN of I—IV stages and EH of II—III stages, aged 31 to 82 years old (an average age was 59.38±1.58 years). They were also genotyped for rs4646994 (I/D) ACE and for rs1799983 (G894T) eNOS gene polymorphisms with the use of polymerase chain reaction. Among the patients with I/D polymorphism of ACE gene there were 24 (14.0%) pts with genotype II, 32 (18.7%) pts with genotype ID and 26 (15.2%) subjects with genotype DD. Among the participants with G894T eNOS gene polymorphism GG genotype was revealed in 29 (16.9%) pts, GT genotype was found in 33 (19.3%) cases and 27 (15.8%) examined persons had TT genotype. Standard parameters of lipid profile were measured in all included pts with a use of an immune enzyme method. Glucose oxidase and immune enzyme methods were used to define serum glucose and insulin levels; level of glycosylated hemoglobin (HbA1C) was detected by fluid chromatography method. Insulin resistance (IR) indices such as HOMA‑IR, triglyceride‑glucose index (TGGI), METS‑IR (metabolic score for insulin resistance) index were calculated by known formulas. Cardiometabolic risk (CMR) of the pts was estimated by ­METS‑IR index. Body mass index (BMI), body fat percentage (BFP), total fat mass (TFM) and fat mass index (FMI) in all the pts were calculated by standard known formulas. Serum uric acid concentration was measured with phosphovolframic method. Dapagliflozin 10 mg/daily was added for 24 weeks to the basic standard antidiabetic therapy including gliclazide or glimepiride and metformin combined with lipid lowering therapy containing atorvastatin. The standard therapy was not changed during the whole period of observation.
 Results. No association has been revealed between I/D ACE and G894T eNOS gene polymorphisms in pts with DN and EH, with a noted improvement of lipid blood spectrum due to administration of dapagliflozin in a dose of 10 mg/daily for 24 weeks. It has been established that allele D was associated with a reduction of dapagliflozin efficacy in the correction of carbohydrate metabolism disorders in pts with DN and EH. At presence of allele D (ID and DD) in genotype, the levels of glycemia, insulinemia, HbA1C, IR indices such as HOMA‑IR, TGGI, METS‑IR decreased less effective than in the case of allele D absence (genotype II). In pts with DN and EH who had G894T eNOS gene polymorphism, dapagliflozin 10 mg/daily improved muscle sensitivity to insulin and decreased CMR depended on genotype in the following order: GT >TT >GG, whereas the intensity of glycemia, insulinemia, HbA1C and HOMA‑IR index reduction was found to be associated with genotype as follows: GG >GT >TT. Allele I compared with allele D of I/D ACE gene polymorphism in pts with DN and EH was revealed to be associated with more significant reduction of BFP, TFM and FMI due to dapagliflozin administration. In pts with DN and EH who had G894T eNOS gene polymorphism dapagliflozin 10 mg/daily reduced a body mass due to its influence on fat accumulation but not on muscle tissue both in phenotype of visceral obesity (genotype GG) and in phenotype of sarcopenic obesity (genotype GT). In the realization of hypouricemic effects of dapagliflozin in patients with DN and EH, both genetic factors (D and T alleles of I/D ACE and G894T eNOS gene polymorphisms correspondingly), and metabolic factors (initial levels of HbA1C and UA together with anthropometric parameters characterized visceral obesity phenotype such as BMI, TFM and FMI) were involved.
 Conclusions. In pts with DN and EH, the association of I/D ACE (rs4646994) and G894T eNOS (rs1799983) gene polymorphisms with metabolic effects of dapagliflozin 10 mg/daily has been established. A presence of allele D of I/D ACE and allele T of G894T eNOS gene polymorphisms in genotype was concluded to be associated with less significant metabolic effects of dapagliflozin compared with an absence of these alleles in genotype.

Heart Failure, Investigator-Reported Sleep Apnea and Dapagliflozin: A Patient-Level Pooled Meta-Analysis of DAPA-HF and DELIVER

Sleep apnea is more common in patients with heart failure (HF) than in the general population, but little is known about its association with clinical outcomes in various HF phenotypes or how it might modify the effect of HF therapy. To examine the prevalence of sleep apnea, its association with outcomes and the effects of dapagliflozin in patients with HF with and without sleep apnea in a pooled analysis of 2 trials comparing dapagliflozin to placebo in HFrEF (DAPA-HF trial) and HFmrEF/HFpEF (DELIVER trial). A history of sleep apnea was investigator-reported. The primary outcome was a composite of worsening HF or cardiovascular death. The prevalence of sleep apnea was 5.7% and 7.8% in patients with HFrEF and HFmrEF/HFpEF, respectively. The primary outcome occurred at a rate of 16.0 in participants with sleep apnea compared to 10.6 per 100 person-years in those without (adjusted HR 1.29 [95%CI, 1.10-1.52]). Compared with placebo, dapagliflozin reduced the risk of the primary endpoint to the same extent in patients with (HR 0.78 [95% CI, 0.59-1.03]) and without sleep apnea (HR 0.79 [0.72-0.87]) [Pinteraction = 0.93]. The beneficial effects of dapagliflozin on other clinical outcomes and symptom burden, physical function, and quality of life were consistent in participants with and without sleep apnea. In DAPA-HF and DELIVER, the true prevalence of sleep apnea was likely underestimated. An investigator-reported history of sleep apnea was associated with higher rates of worsening HF events. The benefits of dapagliflozin on clinical outcomes were consistent in patients with and without sleep apnea. Unique identifiers: NCT01920711 CONDENSED ABSTRACT: In a pooled analysis of the DAPA-HF and DELIVER trials of more than 11,000 patients with heart failure (HF) across the range of ejection fractions, an investigator-reported history of sleep apnea was associated with higher rates of worsening HF events but not mortality. The beneficial effects of dapagliflozin on clinical outcomes were consistent in patients with and without sleep apnea. These findings provide further evidence for dapagliflozin as a new treatment option for patients with heart failure across the range of ejection fractions.

Effects of Dapagliflozin in Patients in Asia: A Post Hoc Subgroup Analysis From the DELIVER Trial

BackgroundPatients with heart failure (HF) with mildly reduced or preserved ejection fraction in Asia may have different clinical characteristics and outcomes compared with patients from other parts of the world. ObjectivesThe purpose of this study was to investigate the clinical characteristics, safety, and efficacy of dapagliflozin in patients in Asia vs outside Asia in the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure) trial. MethodsIn the DELIVER trial, patients with HF and left ventricular ejection fraction >40% were enrolled across 353 sites in 20 countries. The effects of dapagliflozin vs placebo on primary (composite of worsening HF or cardiovascular death) and secondary outcomes were compared in patients from Asia vs outside Asia. ResultsAmong 6,263 participants, 1,226 (19.6%) were enrolled in Asia. Participants from Asia were less likely to have diabetes, hypertension, history of myocardial infarction, or obesity. After adjusting for clinically relevant characteristics, those in Asia had similar risks of primary composite outcome compared with those from outside Asia (HR: 0.97; 95% CI: 0.82-1.15). Those in Asia had a lower risk of all-cause mortality compared with those enrolled outside Asia (HR: 0.54; 95% CI: 0.44-0.66). Enrollment from Asia did not modify the effect of dapagliflozin on the primary outcome (Pinteraction = 0.54). Serious adverse events and rates of drug discontinuation were also balanced in both treatment arms, irrespective of enrollment in Asia vs outside Asia. ConclusionsIn the global DELIVER trial, dapagliflozin reduced the risk of CV death or worsening HF events and was well tolerated among participants enrolled in both Asia and other geographic regions.

Effect of dapagliflozin in patients with heart failure with mildly reduced or preserved ejection fraction treated with beta-blockers: the DELIVER trial

Abstract Background While beta-blockers are not recommended for the treatment of HFpEF according to the latest ESC and AHA/ACC/HFSA guidelines, these therapies remain commonly used for comorbidity management. There has been concern that beta-blockers might adversely influence clinical outcomes by limiting chronotropic response in HFpEF. Purpose To examine the contemporary use and implications of beta-blocker use in patients with HFmrEF or HFpEF. Methods In the DELIVER trial, a total of 6,263 patients with symptomatic HF with LVEF >40% were randomized to dapagliflozin or placebo across 20 countries. Efficacy and safety outcomes were examined according to beta-blocker use at randomization. The primary outcome was cardiovascular death or worsening HF. Results Overall, beta-blockers were used in 5,177 patients (83%), with wide variation ranging from Mexico (60%) to Poland (93%). Nearly all patients taking beta-blockers had at least 1 potential indication (n = 5,106 [99%]), such as hypertension (n = 4,623 [89%]), atrial fibrillation/flutter (n= 2,969 [57%]), coronary artery disease (n= 2,744 [53%]), or previous LVEF< = 40% that has since improved (n = 991 [19%]). Beta-blocker use was not associated with a higher risk of the primary outcome in covariate-adjusted models (HR 0.68 [95% CI 0.59-0.80]; Left Panel). Dapagliflozin consistently reduced the risk of the primary outcome in patients taking beta-blockers (HR 0.82 [95% CI 0.72- 0.94]) and those not taking beta-blockers (HR 0.79 [95% CI 0.61-1.03]; P for interaction = 0.85), with similar findings for key secondary endpoints (Right Panel). Adverse events were balanced between patients randomized to dapagliflozin and placebo, regardless of background beta-blocker use. Conclusions In patients with HFmrEF or HFpEF enrolled in DELIVER, 4 out of 5 participants were treated with a beta-blocker, with virtually all these patients having at least 1 potential indication for use. Beta-blocker use was not associated with a higher risk of worsening HF or cardiovascular death. Dapagliflozin consistently and safely reduced clinical events, irrespective of background beta-blocker use.

Effect of dapagliflozin in patients in Asia with heart failure with mildly reduced or preserved ejection fraction: insights from DELIVER

Abstract Background A large and growing fraction of the global heart failure (HF) population lives in Asia. One-fifth of participants in the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients with Preserved Ejection Fraction Heart Failure) trial were enrolled from Asia, providing a rich source of contemporary data to understand their unique clinical profiles and responses to sodium-glucose cotransporter 2 (SGLT2) inhibition. Purpose To assess the differences in clinical characteristics, outcomes, and response to dapagliflozin in patients from Asia vs outside Asia among patients with HF with mildly reduced or preserved ejection fraction in the DELIVER trial. Methods DELIVER was a global randomized clinical trial enrolling across 353 sites in 20 countries. Baseline clinical characteristics from patients enrolled in DELIVER trial were compared between patients in Asia vs outside Asia. The primary outcome was a composite of worsening HF or cardiovascular (CV) death. The effect of dapagliflozin on primary and secondary outcomes were compared in patients in Asia vs outside Asia. Results Among 6,263 participants in the DELIVER trial, 1,226 (19.6%) were enrolled in Asia (310 in China, 422 in Japan, and 318 in Taiwan, and 176 in Vietnam). Compared to patients outside Asia, participants from Asia were similar in age, more likely to be men with previous HF hospitalization, less likely to have obesity, diabetes, hypertension, or history of myocardial infarction, and had lower symptom burden despite similar natriuretic peptide levels (Figure 1). After adjusting for age, sex, and baseline LVEF, those in Asia faced similar risks of HF events but lower risk of mortality compared with those enrolled outside Asia (all-cause mortality Asia vs. outside Asia: HR 0.60, 95% confidence interval [CI] 0.49 – 0.72, Table 1). Within Asia, all-cause mortality was highest in Vietnam (6.8 per 100 person-year [py]), followed by Taiwan (6.7 per 100 py), Japan (3.5 per 100 py) and China (3.3 per 100 py). Dapagliflozin reduced the primary outcome in participants enrolled in Asia (hazard ratio [HR] 0.89, 95% CI 0.67-1.18) and outside Asia (HR 0.80, 95% CI 0.71 – 0.92) to a similar extend (P-interaction = 0.54, Figure 1). Similarly, region did not modify the treatment effect of dapagliflozin on CV death, HF hospitalization, all-cause death, CV death and recurrent HF events, or changes in Kansas City Cardiomyopathy Questionnaire scores (P-interaction > 0.30 for all). Serious adverse events and rates of drug discontinuation were also balanced in both treatment arms, irrespective of enrollment in Asia vs. outside Asia. Conclusions In the global DELIVER trial, dapagliflozin reduced the risk of CV death or HF events and was well tolerated both among participants enrolled in Asia and other geographic regions.Figure 1Table 1

Effect of Dapagliflozin in Patients with Heart Failure: A Systematic Review and Meta-Analysis.

Heart failure (HF) is a major cause of recurrent hospitalization and death worldwide. Sodium-glucose cotransporter-2 inhibitors including dapagliflozin are anti-diabetic drugs with promising cardiovascular (CV) effects. We performed systematic review and meta-analysis of randomized controlled trials investigating the effects of dapagliflozin in heart failure patients. We searched PubMed, Scopus and ScienceDirect databases. A total of 1,567 studies from January 2017 to September 10, 2022, were screened. After applying exclusion criteria, 22 studies were retrieved for full-text screening, and nine of them were eligible for this meta-analysis. Effect estimates for dichotomous variables were expressed as risk ratio (RR) and 95% CI. The primary outcomes were the incidence of all-cause mortality, hospitalization due to HF, and CV death. This review was registered on PROSPERO with ID CRD42022347793. A total of 14,032 patients were included. The overall risk ratio of all-cause mortality favored the dapagliflozin group over the placebo/standard therapy group (RR = 0.89, 95% CI: 0.82-0.97, P = 0.006) and the pooled studies were not heterogenous (I2 = 0%). Additionally, dapagliflozin significantly reduced the hospitalization due to heart failure (RR = 0.76, 95% CI: 0.70-0.84, P > 0.00001, I2 = 0%), cardiovascular death (RR = 0.87, 95% CI: 0.78-0.97, P = 0.01, I2 = 0%) and their composite outcomes. Dapagliflozin reduces the risk of all-cause mortality, heart failure hospitalizations and cardiovascular death in a wide range of heart failure patients.

#5217 PROTOCOL AND PRELIMINARY RESULTS OF DAPAGLIFLOZIN IN INACTIVE LUPUS NEPHRITIS CROSS-OVER RANDOMIZED TRIAL

Abstract Background and Aims Sodium-glucose co-transporter 2 (SGLT2) inhibitors slow the progression of chronic kidney disease (CKD) with and without type 2 diabetes. Lupus nephritis (LN) patients under immunosuppression were excluded from the most important trials with SGLT2 inhibitors. Thus, efficacy and tolerance of these drugs are unknown in such patients. The present trial will assess the effect of Dapagliflozin in patients with inactive Lupus Nephritis with residual proteinuria. Method For this cross-over randomized trial, we will include adult patients with LN class III, IV (+/-V) without active nephritis but with proteinuria > 500mg/24h or UPC > 200mg/g and eGFR ≥ 20ml/min, in the maintenance treatment. RAAS inhibition should be stable for at least four weeks before the randomization. We will exclude patients with other etiologies of CKD, those with active LN lesions on the recent biopsy (AI>2), use of induction therapy in the last 12 months (Cyclophosphamide, Mycophenolate Mofetil >2 g/day and Calcineurin inhibitors) and prednisone dose ≥ 20 mg/day. Due to safety issues, we will exclude patients with recurrent urinary infections (>3 times/year). They will be randomized to receive Dapagliflozin 10mg on top of standard of care therapy or not. After 24 weeks the groups will be switched and those without Dapagliflozin will receive it for the next 24 weeks. Primary endpoint will be reduction of proteinuria compared to baseline at 6 and 12 months. Secondary endpoints will include sustained reduction of eGFR > 30%; changes in weight and blood pressure compared to baseline; and number of infections on Dapagliflozin treatment versus exclusive standard of care therapy. The sample size was calculated for 28 patients enrolled providing 80% power to detect a 25% relative risk reduction in proteinuria (α level of 0.05). Results From 85 screened class III, IV (+/- V) LN patients under maintenance therapy, we excluded 65 due to active nephritis, low proteinuria or low eGFR. Until now we included 17 patients that were randomized 1:1 to start the treatment with Dapagliflozin on top of standard care or remain with the usual therapy for 24 weeks. Patients’ baseline characteristics are described in Table 1. All patients randomized were using Mycophenolate Mofetil ≤2 g/day and RAAS inhibition and 14 of them were receiving Hydroxychloroquine. Conclusion We expect that the present trial will determine whether the SGLT2 inhibitor Dapagliflozin, added to LN maintenance therapy, could safely reduce the residual proteinuria of inactive LN patients.

58. Blood Pressure Reduction Effect of Dapagliflozin in Patients with Type 2 Diabetes Mellitus: a Systematic Review

Hypertension is a common comorbidity in patients with Type 2 Diabetes Mellitus (T2DM). One of the new anti-diabetic classes is Sodium-Glucose Cotransporter-2 (SGLT2) inhibitor which is still widely tested in clinical trials for indications beyond T2DM. However, the effect on blood pressure in T2DM patients receiving SGLT2 inhibitors is still not well known. This study wants to find out the effect of Dapagliflozin on blood pressure in patients with T2DM. This study was conducted on 1–7 January 2023. Two independent researchers systematically extracted data from several databases, such as PubMed Central (PMC), Science Direct, and PUBMED by using MeSH terminology of keywords SGLT2 inhibitor and blood pressure. The extracted studies were then analyzed and selected according to our inclusion criteria such as studies in the last 5 years, T2DM patients receiving dapagliflozin, cohort studies, and case-control studies. We excluded systematic reviews, meta-analyses, case series, case reports, studies on pregnant women, children, and animals. Research quality was assessed using Newcastle-Ottawa (NOS). From 4 cohort studies (1664 subjects from various countries), all of them showed dapagliflozin administration resulted in reduction of systolic blood pressure. In some studies, the blood pressure-lowering effect of dapagliflozin administration was greater when combined with other classes of anti-diabetic drugs like Glucagon-Like Peptide-1 (GLP1) agonist; All studies have proven good quality based on NOS. In conclusion, dapagliflozin had a blood pressure-lowering effect in T2DM patients. However, further study is needed to confirm these findings.

Nephroprotective Effects of Dapagliflozin in Patients with Type 2 Diabetes.

Objective This study analyzed changes in the estimated glomerular filtration rate calculated using cystatin C (eGFRcys) and sodium excretion in the urine after administering dapagliflozin as an add-on therapy to conventional treatment for diabetes. Methods This was a single-center, single-group, prospective interventional study. Dapagliflozin was administered to improve the plasma glucose control in 30 subjects with type 2 diabetes mellitus (age 53±8 years old; 66.6% men). Blood and urine tests were performed before and 6 and 12 months after dapagliflozin administration. The daily sodium excretion was estimated with the Kawasaki formula using second-morning urine samples. Results The eGFRcys did not markedly differ before and 6 months after the dapagliflozin administration but was significantly increased after 12 months (p<0.001), and the estimated daily sodium excretion was also significantly increased (p<0.001 at 6 months and p=0.002 at 12 months). The systolic and diastolic blood pressures tended to decrease after administration. The HbA1c level after the administration of dapagliflozin tended to be lower in the T3 group, showing the smallest increase in changes in the estimated daily sodium excretion from baseline to 6 months (28.2-107.5 mEq/day), than in the combined groups of T1 (219.5-110.1 mEq/day) and T2 (101.4-28.9 mEq/day). In contrast, the eGFRcys was significantly higher in the combined groups of T1 and T2 than that in the T3 group at both 6 and 12 months (p=0.031 and p=0.007, respectively). Conclusions Add-on therapy with dapagliflozin increased the urinary sodium excretion and decreased the blood pressure even in the early phase of this therapy. Our results suggest that dapagliflozin add-on therapy may exert nephroprotective effects in subjects with type 2 diabetes mellitus.

PS-C26-7: A SINGLE-CENTER, RETROSPECTIVE STUDY OF BLOOD PRESSURE EFFECTS OF DAPAGLIFLOZIN IN PATIENTS WITH CHRONIC KIDNEY DISEASE

Backgrounds: Sodium-glucose transporter 2(SGLT2) inhibitors are reported to have blood pressure lowering effects in addition to glucose-lowering effects. Previous studies have shown SGLT2 inhibitors, including dapagliflozin, reduce systolic blood pressure among patients with type 2 diabetes. Its mechanism is still uncertain; however, previous studies suggest plasma reduction by osmotic diuresis and natriuresis may contribute to lowering blood pressure. Dapagliflozin was recently approved as the treatment for chronic kidney disease in Japan. Blood-pressure lowering effects of SGLT2 inhibitors among patients with chronic kidney disease (CKD) are still unknown; therefore, we investigated blood-pressure effects of dapagliflozin in patients with CKD. Design and method: Patients with chronic kidney disease (estimated glomerular filtration rate (eGFR) of less than 60 mL/min per 1.73 m2, or markers of kidney damage, or both, of at least 3 months duration) were given 10 mg dapagliflozin daily for at least 4 weeks. Patients who had any changes in their antihypertensive drug prescription during this observation period were excluded. Clinical data including blood pressure measurements, eGFR, urine protein/creatinine ratio, and urinary sodium excretion before and after administration were taken and compared. Results: Contrary to previous reports, there was no significant difference in blood pressure at two months after administration. However, there was a trend of blood pressure decline at four months. Since this study is retrospective, measurement procedures were not aligned among patients, and body fluid evaluation was not considered. These inconsistent conditions may have affected the results. Also, dapagliflozin was administered to most patients in this study at the end of fall or beginning of winter, as it was approved for CKD patients in Japan in August 2021. Decreasing temperature may have limited or countervailed the blood pressure lowering effect of dapagliflozin in the first two months. Conclusions: Our findings indicate that the use of Dapagliflozin may serve as adjunct blood pressure lowering therapy in patients with CKD. Prospective study is needed to further investigate the blood pressure effects of dapagliflozin in CKD patients.

The Clinical Effect of Dapagliflozin in Patients with Angiographically Confirmed Coronary Artery Disease and Concomitant Type 2 Diabetes Mellitus

Nowadays treatment of patients with coronary artery disease (CAD) and concomitant type 2 diabetes mellitus (DM) needs further study.&#x0D; The aim. Evaluation of the clinical effect and glycemic variability of dapagliflozin in patients with angiographically confirmed CAD and concomitant type 2 DM.&#x0D; Materials and methods. The study involved 47 patients with angiographically confirmed CAD. The patients underwent laboratory blood tests, electrocardiography, echocardiography, continuous glucose monitoring and percutaneous coronary intervention (PCI). Depending on the usage of dapagliflozin 10 mg, the patients were divided into 2 groups: group I (+SGLT2i, n = 24) and group II (–SGLT2i, n = 23). The average follow-up period was 16 months.&#x0D; Results. Distribution of the examined patients by age, anthropometric characteristics, duration of DM, functional state of the heart and kidneys, smoking, the presence of acute cardiovascular events and previous PCI showed no statistically significant difference. In patients of group I, on the background of taking SGLT2i, a decrease in body mass index and improved glycemic profile were revealed. Patients in group II were more likely to have complaints of angina (4 [17.3%] vs 1 [4.3%], p&gt;0.05); repeated coronary angiography in this group was significantly more likely to reveal progression to atherosclerotic CAD (4 [17.3%], p&lt;0.05) which required re-revascularization. No fatalities were detected during the follow-up.&#x0D; Conclusion. Dapagliflozin has improved glycemic and lipid profile of the blood and long-term prognosis after PCI. Adding this drug to the treatment reduces the clinical progression of CAD, the need for re-hospitalization and cardiac revascularization.

MO634: Effects of Dapagliflozin in Patients with Heart Failure

Abstract BACKGROUND AND AIMS In patients with type 2 diabetes, inhibitors of sodium–glucose cotransporter 2 (SGLT2) reduce the risk of a first hospitalization for heart failure, possibly through glucose-independent mechanisms. More data are needed regarding the effects of SGLT2 inhibitors in patients with established heart failure and a reduced ejection fraction, regardless of the presence or absence of type 2 diabetes. METHOD A multicenter prospective cohort study, where 225 patients with heart failure (III and IV by NYHA) and an ejection fraction of 45% or less to receive either dapagliflozin (10 mg once daily) or placebo, in addition to basic therapy. The primary outcome was a composite of worsening heart failure (hospitalization or an urgent visit resulting in intravenous therapy for heart failure) or cardiovascular death. RESULTS After 12 months, the primary outcome occurred in 17 of 111 patients (15.31%) in the dapagliflozin group and in 24 of 114 patients (21.05%) in the placebo group {HR 0.74 [95% confidence interval (CI), 0.65–0.85]; P &amp;lt; 0.001}. A first worsening heart failure event occurred in 10 patients (9.0%) in the dapagliflozin group and in 16 patients (14.0%) in the placebo group [HR 0.70 (95% CI 0.59–0.85)]. Death from cardiovascular reasons occurred in six patients (5.4%) in the dapagliflozin group and in 11 patients (9.6%) in the placebo group [HR 0.80 (95% CI 0.69–0.95)]; 12 patients (10.8%) and 15 patients (13.1%), respectively, died from other causes [HR 0.83 (95% CI 0.71–0.96)]. Findings in patients with diabetes were not significantly pronounced than in patients without diabetes. The frequency of adverse events related to volume depletion, renal dysfunction and hypo/hyperglycemia did not differ between treatment groups. CONCLUSION Among patients with heart failure and a reduced ejection fraction, the risk of worsening heart failure or death from cardiovascular events was lower among those who received dapagliflozin than among those who received placebo, regardless of the presence or absence of diabetes.

FC082: Effects of Dapagliflozin in Patients with Chronic Kidney Disease According to Background Angiotensin-Converting Enzyme Inhibitor and Angiotensin Receptor Blocker Dose

Abstract BACKGROUND AND AIMS Treatment guidelines for patients with chronic kidney disease (CKD) recommend renin–angiotensin system inhibition (RASi) with angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) to reduce the risk of kidney failure. However, patients with more advanced CKD do not always tolerate RASi. The sodium-glucose cotransporter 2 inhibitor dapagliflozin reduced the risk of kidney failure in patients with CKD in the DAPA-CKD trial. We performed a post hoc analysis of this trial to assess the efficacy of dapagliflozin by baseline dose level of ACEi or ARB. METHOD Participants with CKD [estimated glomerular filtration rate (eGFR) 25–75 mL/min/1.73 m2; urinary albumin-to-creatinine ratio (UACR) 200–5000 mg/g), with or without type 2 diabetes, were randomized 1:1 to dapagliflozin 10 mg or placebo, once daily. Participants were to be treated with the recommended target dose, or a stable tolerated dose of ACEi or ARB, unless medically contraindicated, for ≥4 weeks prior to inclusion. The primary outcome was a composite of sustained ≥50% eGFR decline, end-stage kidney disease or death from a kidney or cardiovascular cause. A prespecified kidney-specific secondary outcome was the same as the primary endpoint, but without cardiovascular death. A composite cardiovascular outcome (heart failure hospitalization or cardiovascular death), and all-cause mortality were other secondary endpoints. Time-to-event analyses were performed to assess the effects of dapagliflozin versus placebo according to baseline prescription and dose of ACEi or ARB treatment. RESULTS Of 4296 (99.9%) participants with available data on ACEi/ARB doses, 1231 (28.7%) were using the target dose, 1867 (43.5%) a dose ≥50% to &amp;lt;100% of target, 1068 (24.9%) a dose 0 to &amp;lt;50% of target and 130 (3.0%) were not using an ACEi/ARB. In the placebo group, the event rate for the primary outcome was highest among participants not using ACEi/ARBs compared to the other subgroups (figure 1). The benefit of dapagliflozin on the primary composite outcome was consistent regardless of use or non-use of the target dose of ACEi/ARBs. This consistency was maintained for the secondary outcomes (Figure 1). Dapagliflozin compared to placebo reduced the rate of eGFR decline over the study by –0.93 [95% confidence interval (95% CI) 0.61–1.25] mL/min/1.73 m2. This effect was present regardless of the use or non-use of target doses of ACEi/ARBs (P for interaction 0.877). CONCLUSION Dapagliflozin was similarly efficacious in reducing major adverse kidney and cardiovascular outcomes in participants with CKD regardless of the use or dose of ACEi/ARB.

Quételet (body mass) index and effects of dapagliflozin in chronic kidney disease.

To assess the effects of dapagliflozin in patients with chronic kidney disease (CKD) and albuminuria, with and without type 2 diabetes, stratified by the Quételet (body mass) index (BMI). We randomized 4304 adult patients with an estimated glomerular filtration rate (eGFR) of 25-75 ml/min/1.73m2 and urinary albumin-to-creatinine ratio of 200-5000 mg/g to dapagliflozin 10mg/day or placebo. The primary outcome was a composite of sustained decline in eGFR of 50% or more, kidney failure, or death from kidney or cardiovascular causes. Secondary outcomes included kidney composite endpoint (primary composite endpoint without cardiovascular death), cardiovascular composite endpoint (hospitalized heart failure/ cardiovascular death), and all-cause mortality. We categorized participants according to World Health Organization BMI criteria: lean/ideal (<25 kg/m2 ), overweight (25-< 30 kg/m2 ), grade 1 obesity (30-<35 kg/m2 ), and grade 2/3 obesity (≥35 kg/m2 ). Of 4296 (99.8%) randomized participants, 888 (20.7%), 1491 (34.7%), 1136 (26.4%), and 781 (18.2%) were categorized as lean/ideal, overweight, grade 1 obesity, and grade 2/3 obesity, respectively. Median follow-up was 2.4 years. Benefits of dapagliflozin were observed independent of baseline BMI for primary and secondary endpoints. Hazard ratios (95% CI) for dapagliflozin versus placebo for the primary composite endpoint were 0.60 (0.43, 0.85), 0.55 (0.40, 0.75), 0.71 (0.49, 1.04), and 0.57 (0.37, 0.87) among participants in the lean/ideal, overweight, grade 1 obesity, and grade 2/3 obesity groups (interaction P=.72). Among participants with CKD and albuminuria, with or without type 2 diabetes, kidney and cardiovascular benefits of dapagliflozin were evident and consistent across the BMI spectrum.

Serial Assessment of High-Sensitivity Cardiac Troponin and the Effect of Dapagliflozin in Patients With Heart Failure With Reduced Ejection Fraction: An Analysis of the DAPA-HF Trial.

Circulating high-sensitivity cardiac troponin T (hsTnT) predominantly reflects myocardial injury, and higher levels are associated with a higher risk of worsening heart failure and death in patients with heart failure with reduced ejection fraction. Less is known about the prognostic significance of changes in hsTnT over time, the effects of dapagliflozin on clinical outcomes in relation to baseline hsTnT levels, and the effect of dapagliflozin on hsTnT levels. DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) was a randomized, double-blind, placebo-controlled trial of dapagliflozin (10 mg daily) in patients with New York Heart Association class II to IV symptoms and left ventricular ejection fraction ≤40% (median follow-up, 18.2 months). hsTnT (Roche Diagnostics) was measured at baseline in 3112 patients and at 1 year in 2506 patients. The primary end point was adjudicated worsening heart failure or cardiovascular death. Clinical end points were analyzed according to baseline hsTnT and change in hsTnT from baseline to 1 year. Comparative treatment effects on clinical end points with dapagliflozin versus placebo were assessed by baseline hsTnT. The effect of dapagliflozin on hsTnT was explored. Median baseline hsTnT concentration was 20.0 (25th-75th percentile, 13.7-30.2) ng/L. Over 1 year, 67.9% of patients had a ≥10% relative increase or decrease in hsTnT concentrations, and 43.5% had a ≥20% relative change. A stepwise gradient of higher risk for the primary end point was observed across increasing quartiles of baseline hsTnT concentration (adjusted hazard ratio Q4 versus Q1, 3.44 [95% CI, 2.46-4.82]). Relative and absolute increases in hsTnT over 1 year were associated with higher subsequent risk of the primary end point. The relative reduction in the primary end point with dapagliflozin was consistent across quartiles of baseline hsTnT (P-interaction=0.55), but patients in the top quartile tended to have the greatest absolute risk reduction (absolute risk difference, 7.5% [95% CI, 1.0%-14.0%]). Dapagliflozin tended to attenuate the increase in hsTnT over time compared with placebo (relative least squares mean reduction, -3% [-6% to 0%]; P=0.076). Higher baseline hsTnT and greater increase in hsTnT over 1 year are associated with worse clinical outcomes. Dapagliflozin consistently reduced the risk of the primary end point, irrespective of baseline hsTnT levels. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03036124.

Effect of dapagliflozin on urinary albumin excretion in patients with chronic kidney disease with and without type 2 diabetes: a prespecified analysis from the DAPA-CKD trial

Reductions in albuminuria are associated with a subsequent lower risk of kidney failure in patients with chronic kidney disease. The SGLT2 inhibitor dapagliflozin significantly reduced albuminuria in patients with type 2 diabetes and normal or near-normal kidney function. Whether this effect persists in patients with chronic kidney disease with and without type 2 diabetes is unknown. We assessed the effects of dapagliflozin on albuminuria in patients with chronic kidney disease with and without type 2 diabetes in the dapagliflozin and prevention of adverse outcomes in chronic kidney disease (DAPA-CKD) trial. DAPA-CKD was a multicentre, double-blind, placebo-controlled, randomised trial done at 386 sites in 21 countries. Patients were eligible for the trial if they had chronic kidney disease, defined as an estimated glomerular filtration rate (eGFR) between 25 mL/min per 1·73 m2 and 75 mL/min per 1·73 m2 and a urinary albumin-to-creatinine ratio (UACR) between 200 mg/g and 5000 mg/g (22·6 to 565·6 mg/mmol). Participants were randomly assigned to dapagliflozin 10 mg (AstraZeneca; Gothenburg, Sweden) once daily or matching placebo, in accordance with the sequestered, fixed randomisation schedule, using balanced blocks to ensure an approximate 1:1 ratio. Change in albuminuria was a pre-specified exploratory outcome of DAPA-CKD. Regression in UACR stage, defined as a transition from macroalbuminuria (≥300 mg/g) to microalbuminuria or normoalbuminuria (<300 mg/g), and progression in UACR stage, defined as a transition from less than 3000 mg/g to 3000 mg/g or greater, were additional discrete endpoints. The trial is registered with ClinicalTrials.gov, NCT03036150. Between Feb 2, 2017, and April 3, 2020, 4304 patients were recruited and randomly assigned to either dapagliflozin (n=2152) or placebo (n=2152). Median UACR was 949 mg/g (IQR 477 to 1885). Overall, compared with placebo, dapagliflozin reduced geometric mean UACR by 29·3% (95% CI -33·1 to -25·2; p<0·0001); relative to placebo, treatment with dapagliflozin resulted in a geometric mean percentage change of -35·1% (95% CI -39·4 to -30·6; p<0·0001) in patients with type 2 diabetes and -14·8% (-22·9 to -5·9; p=0·0016) in patients without type 2 diabetes over the follow-up visits (pinteraction<0·0001) Among 3860 patients with UACR of 300 mg/g or greater at baseline, dapagliflozin increased the likelihood of regression in UACR stage (hazard ratio 1·81, 95% CI 1·60 to 2·05). Among 3820 patients with UACR less than 3000 mg/g at baseline, dapagliflozin decreased the risk of progression in UACR stage (0·41, 0·32 to 0·52). Larger reductions in UACR at day 14 during dapagliflozin treatment were significantly associated with attenuated eGFR decline during subsequent follow-up (β per log unit UACR change -3·06, 95% CI -5·20 to -0·90; p=0·0056). In patients with chronic kidney disease with and without type 2 diabetes, dapagliflozin significantly reduced albuminuria, with a larger relative reduction in patients with type 2 diabetes. The similar effects of dapagliflozin on clinical outcomes in patients with or without type 2 diabetes, but different effects on UACR, suggest that part of the protective effect of dapagliflozin in patients with chronic kidney disease might be mediated through pathways unrelated to reduction in albuminuria.
