Background: A sizeable proportion of patients with chronic kidney disease (CKD) are reported to be frail. Here we examined the safety andefficacy of dapagliflozin in patients with CKD by frailty level.Methods: Adults with CKD, with/without type 2 diabetes, with an estimated glomerular filtration rate (eGFR) of 25–75 mL/min/1.73 m2 , andurinary albumin-to-creatinine ratio 200–5 000 mg/g were randomized to dapagliflozin (10 mg/day) or placebo. The primary endpoint was a com-posite of sustained ≥50% eGFR decline, end-stage kidney disease (ESKD), or death from kidney or cardiovascular (CV) causes.Results: Frailty index (FI), assessed by Rockwood cumulative deficit approach, was calculable in 4 303/4 304 (99.9%) patients: 1 162 (27.0%)in not-to-mildly frail (FI ≤0.210), 1 642 (38.2%) in moderately frail (FI 0.211–0.310), and 1 499 (34.8%) in severely frail categories (FI >0.311).Dapagliflozin reduced the risk of the primary composite endpoint across all FI categories (hazard ratios [95% confidence interval {CI}]: 0.50[0.33–0.76], 0.62 [0.45–0.85], and 0.64 [0.49–-0.83], respectively; p-interaction = 0.67). Results were similar for secondary outcomes includ-ing kidney composite outcome (sustained ≥50% eGFR decline, ESKD or death from kidney cause; p-interaction = 0.44), CV endpoint (heartfailure hospitalization or CV death; p-interaction = 0.63), and all-cause mortality (p-interaction p = .42). Results were consistent when usingFI as a continuous variable. Occurrence of serious adverse events was numerically lower in patients receiving dapagliflozin versus placeboin all FI categories (16.9% vs 20.1%, 26.3% vs 30.7%, and 42.9% vs 47.8%, in not-to-mildly, moderately, and severely frail categories,respectively).Conclusions: The relative benefit of dapagliflozin for all outcomes was consistent across all frailty categories, with no difference in associatedsafety., BACKGROUND: A sizeable proportion of patients with chronic kidney disease (CKD) are reported to be frail.

BACKGROUND: Acute hospitalizations are common in patients with chronic kidney disease (CKD) and often lead to decreases in health-related quality of life and increased care costs. OBJECTIVE: To determine the effects of dapagliflozin on first hospitalizations and all (first and subsequent) hospitalizations and to explore effects on cause-specific hospitalizations. DESIGN: Post hoc analysis of a randomized, double-blind, placebo-controlled clinical trial. (ClinicalTrials.gov: NCT03036150). SETTING: 386 ambulatory practice sites in 21 countries from 2 February 2017 through 12 June 2020. PARTICIPANTS: Adults with an estimated glomerular filtration rate of 25 to 75 mL/min/1.73 m2 and a urinary albumin-creatinine ratio of 200 to 5000 mg/g, with and without type 2 diabetes. INTERVENTION: Dapagliflozin, 10 mg once daily, or matching placebo (1:1 ratio). MEASUREMENTS: The effects of dapagliflozin on first hospitalizations for any cause, all hospitalizations, and cause-specific (first and recurrent) hospitalizations were determined. The reported system organ class was used to evaluate reasons for admission. Hospitalizations were analyzed using Cox proportional hazards regression models (first hospitalization), the Lin-Wei-Yang-Ying method (all hospitalizations or death), and negative binomial models (cause-specific hospitalizations). RESULTS: The study included 4304 patients (mean age, 61.8 years; 33.1% women). During a median follow-up of 2.4 years, 2072 hospitalizations were reported among 1224 (28.4%) participants. Compared with placebo, dapagliflozin reduced risk for a first hospitalization (hazard ratio, 0.84 [95% CI, 0.75 to 0.94]) and all hospitalizations or death (rate ratio, 0.79 [CI, 0.70 to 0.89]). There was no evidence that the effects of dapagliflozin on first and all hospitalizations varied by baseline presence of type 2 diabetes (P for interaction = 0.60 for each). Compared with placebo, dapagliflozin reduced the rate of admissions due to cardiac disorders

BackgroundIn the DAPA-CKD (Dapagliflozin in Patients with Chronic Kidney Disease) trial, dapagliflozin improved kidney and cardiovascular outcomes in patients with chronic kidney disease (CKD) with or without type 2 diabetes (T2D). In this post hoc analysis of DAPA-CKD, we assessed the effects of dapagliflozin on the correction and prevention of anemia.MethodsThe DAPA-CKD trial randomized patients (1:1) with an estimated glomerular filtration rate of 25 to 75 ml/min/1.73 m2 and a urinary albumin-to-creatinine ratio of 200 to 5000 mg/g to receive dapagliflozin 10 mg or placebo daily. Hematocrit was measured at baseline, 2 weeks, 2 and 4 months, and every 4 months thereafter. Anemia was defined as hematocrit less than 39% in men and less than 36% in women. Correction and incidence of anemia were defined as two consecutive measurements above or below these thresholds relative to baseline, respectively, during follow-up. We classified anemia-related adverse events using data from site investigator reports.ResultsMean age of the 4304 participants was 61.8 years, and 67.5% had T2D. Among the 4292 (99.7%) participants with baseline hematocrit data, 1716 (40.0%) had anemia. Over the 2.4-year median follow-up, patients assigned to dapagliflozin had an increase in hematocrit of 2.3 percentage points (95% confidence interval [CI], 2.1 to 2.5) greater than those assigned to placebo. Among patients with anemia at baseline, anemia was corrected in 443 (53.3%) patients randomized to receive dapagliflozin and 247 (29.4%) patients randomized to receive placebo (hazard ratio, 2.29; 95% CI, 1.96 to 2.68). Among patients without anemia at baseline, 10.4% of patients assigned to dapagliflozin developed incident anemia compared with 23.7% in the placebo group (hazard ratio, 0.39; 95% CI, 0.31 to 0.48). Anemia-related adverse events occurred in 2.2% of patients assigned to dapagliflozin compared with 3.8% assigned to placebo.

Results over a 2.4-year median follow-up show that dapagliflozin is associated with increase in hematocrit, correction of anemia, and reduced risk of incident anemia in patients with CKD with or without type 2 diabetes.
