Efficacy of Dapagliflozin on Renal Function and Outcomes in Patients With Heart Failure With Reduced Ejection Fraction: Results of DAPA-HF.

ABSTRACT:

Background

Many patients with heart failure and reduced ejection fraction (HFrEF) have chronic kidney disease that complicates pharmacological management and is associated with worse outcomes. We assessed the safety and efficacy of dapagliflozin in patients with HFrEF, according to baseline kidney function, in the DAPA-HF trial (Dapagliflozin and Prevention of Adverse-outcomes in Heart Failure). We also examined the effect of dapagliflozin on kidney function after randomization.

Methods

Patients who have HFrEF with or without type 2 diabetes and an estimated glomerular filtration rate (eGFR) ?30 mL·min^-1·1.73 m^-2 were enrolled in DAPA-HF. We calculated the incidence of the primary outcome (cardiovascular death or worsening heart failure) according to eGFR category at baseline (<60 and ?60 mL·min^-1·1.73 m^-2) and used eGFR at baseline as a continuous measure, as well. Secondary cardiovascular outcomes and a prespecified composite renal outcome (?50% sustained decline eGFR, end-stage renal disease, or renal death) were also examined, along with a decline in eGFR over time.

Results

Of 4742 patients with a baseline eGFR, 1926 (41%) had eGFR <60 mL·min^-1·1.73 m^-2. The effect of dapagliflozin on the primary and secondary outcomes did not differ by eGFR category or examining eGFR as a continuous measurement. The hazard ratio (95% CI) for the primary end point in patients with chronic kidney disease was 0.71 (0.59-0.86) versus 0.77 (0.64-0.93) in those with an eGFR ?60 mL·min^-1·1.73 m^-2 (interaction P=0.54). The composite renal outcome was not reduced by dapagliflozin (hazard ratio=0.71 [95% CI, 0.44-1.16]; P=0.17) but the rate of decline in eGFR between day 14 and 720 was less with dapagliflozin, -1.09 (-1.40 to -0.77) versus placebo -2.85 (-3.17 to -2.53) mL·min^-1·1.73 m^-2 per year (P<0.001). This was observed in those with and without type 2 diabetes (P for interaction=0.92).

Conclusions

Baseline kidney function did not modify the benefits of dapagliflozin on morbidity and mortality in HFrEF, and dapagliflozin slowed the rate of decline in eGFR, including in patients without diabetes. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03036124.

Project description:BackgroundPatients with heart failure with reduced ejection fraction (HFrEF) in Asia exhibit many differences from those in other parts of the world.ObjectivesThis study sought to investigate the efficacy and safety of dapagliflozin, compared with placebo, in HFrEF patients in Asia, compared with those elsewhere, enrolled in the DAPA-HF (Dapagliflozin and Prevention of Adverse-outcomes in Heart Failure) trial.MethodsPatients in New York Heart Association functional class II to IV with a left ventricular ejection fraction ≤40% and elevated N-terminal pro-B-type natriuretic peptide were eligible for the DAPA-HF trial. The primary outcome in the DAPA-HF trial was the composite of an episode of worsening HF (HF hospitalization or urgent HF visit requiring intravenous therapy) or cardiovascular death.ResultsOf the 4,744 patients in the DAPA-HF trial, 1,096 (23.1%) were enrolled in Asia; 721 (15.2% overall, 65.8% of patients in Asia) were enrolled in East Asia (237 in China, 343 in Japan, and 141 in Taiwan), 138 (2.9% overall, 12.6% in Asia) in South-East Asia (Vietnam), and 237 (5.0% overall, 21.6% in Asia) in South Asia (India). Patients from Asia had similar rates of worsening HF events and mortality compared with patients elsewhere. Compared with placebo, dapagliflozin reduced the risk of the primary endpoint to the same extent in patients from Asia (HR: 0.65; 95% CI: 0.49 to 0.87) as elsewhere (HR: 0.77; 95% CI: 0.66 to 0.89) (P for interaction = 0.32). Consistent benefits were observed for the other prespecified outcomes and among the regions of Asia. Study drug discontinuation and prespecified adverse events did not differ between regions.ConclusionsDapagliflozin, compared with placebo, reduced the risk of worsening HF events and cardiovascular death to the same extent in Asian patients as elsewhere.

Project description:BackgroundIn the DAPA-HF trial (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure), dapagliflozin, added to guideline-recommended therapies, reduced the risk of mortality and heart failure (HF) hospitalization. We examined the frequency and significance of episodes of outpatient HF worsening, requiring the augmentation of oral therapy, and the effects of dapagliflozin on these additional events.MethodsPatients in New York Heart Association functional class II to IV, with a left ventricular ejection fraction ≤40% and elevation of NT-proBNP (N-terminal pro-B-type natriuretic peptide), were eligible. The primary outcome was the composite of an episode of worsening HF (HF hospitalization or an urgent HF visit requiring intravenous therapy) or cardiovascular death, whichever occurred first. An additional prespecified exploratory outcome was the primary outcome plus worsening HF symptoms/signs leading to the initiation of new, or the augmentation of existing, oral treatment.ResultsOverall, 36% more patients experienced the expanded, in comparison with the primary, composite outcome. In the placebo group, 684 of 2371 (28.8%) patients and, in the dapagliflozin group, 527 of 2373 (22.2%) participants experienced the expanded outcome (hazard ratio, 0.73 [95% CI, 0.65-0.82]; P<0.0001). Each component of the composite was reduced significantly by dapagliflozin. Over the median follow-up of 18.2 months, the number of patients needed to treat with dapagliflozin to prevent 1 experiencing an episode of fatal or nonfatal worsening was 16. Among the 4744 randomly assigned patients, the first episode of worsening was outpatient augmentation of treatment in 407 participants (8.6%), an urgent HF visit with intravenous therapy in 20 (0.4%), HF hospitalization in 489 (10.3%), and cardiovascular death in 295 (6.2%). The adjusted risk of death from any cause (in comparison with no event) after an outpatient worsening was hazard ratio, 2.67 (95% CI, 2.03-3.52); after an urgent HF visit, the adjusted risk of death was hazard ratio, 3.00 (95% CI, 1.39-6.48); and after a HF hospitalization, the adjusted risk of death was hazard ratio, 6.21 (95% CI, 5.07-7.62).ConclusionIn DAPA-HF, outpatient episodes of HF worsening were common, were of prognostic importance, and were reduced by dapagliflozin.

Project description:BackgroundIn a post hoc analysis, the frequency of occurrence of an early decline (dip) in estimated glomerular filtration rate (eGFR) after initiation of dapagliflozin and its association with outcomes were evaluated in patients with heart failure and reduced ejection fraction randomized in the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure trial.MethodsPatients with heart failure with reduced ejection fraction with or without type 2 diabetes and an eGFR ≥30 mL·min-1·1.73 m-2 were randomized to placebo or dapagliflozin 10 mg daily. The primary outcome was the composite of worsening heart failure or cardiovascular death. The extent of the dip in eGFR between baseline and 2 weeks, patient characteristics associated with a >10% decline, and cardiovascular outcomes and eGFR slopes in participants experiencing this decline were investigated. Time-to-event outcomes were assessed in Cox regression from 14 days; eGFR slopes were assessed with repeated-measures mixed-effect models.ResultsThe mean change in eGFR between day 0 and 14 was -1.1 mL·min-1·1.73 m-2 (95% CI, -1.5 to -0.7) with placebo and -4.2 mL·min-1·1.73 m-2 (95% CI, -4.6 to -3.9) with dapagliflozin, giving a between-treatment difference of 3.1 mL·min-1·1.73 m-2 (95% CI, 2.6-3.7). The proportions of patients randomized to dapagliflozin experiencing a >10%, >20%, and >30% decline in eGFR were 38.2%, 12.6%, and 3.4%, respectively; for placebo, they were 21.0%, 6.4%, and 1.3%, respectively. The odds ratio for a >10% early decline in eGFR with dapagliflozin compared with placebo was 2.36 (95% CI, 2.07-2.69; P<0.001). Baseline characteristics associated with a >10% decline in eGFR on dapagliflozin were older age, lower eGFR, higher ejection fraction, and type 2 diabetes. The hazard ratio for the primary outcome in patients in the placebo group experiencing a >10% decline in eGFR compared with ≤10% decline in eGFR was 1.45 (95% CI, 1.19-1.78). The corresponding hazard ratio in the dapagliflozin group was 0.73 (95% CI, 0.59-0.91; Pinteraction<0.001). A >10% initial decline in eGFR was not associated with greater long-term decline in eGFR or more adverse events.ConclusionsThe average dip in eGFR after dapagliflozin was started was small and associated with better clinical outcomes compared with a similar decline on placebo in patients with heart failure with reduced ejection fraction. Large declines in eGFR were uncommon with dapagliflozin.RegistrationURL: https://www.Clinicaltrialsgov; Unique identifier: NCT03036124.
