Abstract
BACKGROUND COVID-19 can lead to multiorgan failure. Dapagliflozin, a SGLT2 inhibitor, has significant protective benefits for the heart and kidney. We aimed to see whether this agent might provide organ protection in patients with COVID-19 by affecting processes dysregulated during acute illness. METHODS DARE-19 was a randomised, double-blind, placebo-controlled trial of patients hospitalised with COVID-19 and with at least one cardiometabolic risk factor (ie, hypertension, type 2 diabetes, atherosclerotic cardiovascular disease, heart failure, and chronic kidney disease). Patients critically ill at screening were excluded. Patients were randomly assigned 1:1 to dapagliflozin (10 mg daily orally) or matched placebo for 30 days. Dual primary outcomes were assessed in the intention-to-treat population: the outcome of prevention (time to new or worsened organ dysfunction or death), and the hierarchial composite outcome of recovery (change in clinical status by day 30). Safety outcomes, in patients who received at least one study medication dose, included serious adverse events, adverse events leading to discontinuation, and adverse events of interest. This study is registered with ClinicalTrials.gov, NCT04350593. FINDINGS Between April 22, 2020 and Jan 1, 2021, 1250 patients were randomly assigned with 625 in each group. The primary composite outcome of prevention showed organ dysfunction or death occurred in 70 patients (11·2%) in the dapagliflozin group, and 86 (13·8%) in the placebo group (hazard ratio [HR] 0·80, 95% CI 0·58-1·10; p=0·17). For the primary outcome of recovery, 547 patients (87·5%) in the dapagliflozin group and 532 (85·1%) in the placebo group showed clinical status improvement, although this was not statistically significant (win ratio 1·09, 95% CI 0·97-1·22; p=0·14). There were 41 deaths (6·6%) in the dapagliflozin group, and 54 (8·6%) in the placebo group (HR 0·77, 95% CI 0·52-1·16). Serious adverse events were reported in 65 (10·6%) of 613 patients treated with dapagliflozin and in 82 (13·3%) of 616 patients given the placebo. INTERPRETATION In patients with cardiometabolic risk factors who were hospitalised with COVID-19, treatment with dapagliflozin did not result in a statistically significant risk reduction in organ dysfunction or death, or improvement in clinical recovery, but was well tolerated.

Abstract
This analysis reports a quantitative modeling and simulation approach for oral dapagliflozin, a primarily uridine diphosphate-glucuronosyltransferase (UGT)-metabolized human sodium-glucose cotransporter 2 selective inhibitor. A mechanistic dapagliflozin physiologically based pharmacokinetic (PBPK) model was developed using in vitro metabolism and clinical pharmacokinetic (PK) data and verified for context of use (e.g., exposure predictions in pediatric subjects aged 1 month to 18 years). Dapagliflozin exposure is challenging to predict in pediatric populations owing to differences in UGT1A9 ontogeny maturation and paucity of clinical PK data in younger age groups. Based on the exposure-response relationship of dapagliflozin, twofold acceptance criteria were applied between model-predicted and observed drug exposures and PK parameters (area under the curve and maximum drug concentration) in various scenarios, including monotherapy in healthy adults (single/multiple dose), monotherapy in hepatically or renally impaired patients, and drug-drug interactions with UGT1A9 modulators, such as mefenamic acid and rifampin. The PBPK model captured the observed exposure within twofold of the observed monotherapy data in adults and adolescents and in special population. As a guide to determining dosing regimens in pediatric studies, the verified PBPK model, along with UGT enzyme ontogeny maturation understanding, was used for predictions of dapagliflozin monotherapy exposures in pediatric subjects aged 1 month to 18 years that best matched exposure in adult patients with a 10-mg single dose of dapagliflozin.

Abstract
IMPORTANCE Sodium glucose cotransporter 2 inhibitors reduce morbidity and mortality in patients with heart failure and reduced ejection fraction (HFrEF). Clinicians may find estimates of the projected long-term benefits of sodium glucose cotransporter 2 inhibitors a helpful addition to clinical trial results when communicating the benefits of this class of drug to patients. OBJECTIVE To estimate the projected long-term treatment effects of dapagliflozin in patients with HFrEF over the duration of a patient's lifetime. DESIGN, SETTING, AND PARTICIPANTS Exploratory analysis was performed of Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF), a phase 3 randomized, placebo-controlled clinical trial conducted at 410 sites in 20 countries. Patients with an ejection fraction less than or equal to 40% in New York Heart Association functional classification II to IV and elevated plasma levels of N-terminal pro B-type natriuretic peptide were enrolled between February 15, 2017, and August 17, 2018, with final follow-up on June 6, 2019. Mean (SD) duration of follow-up was 17.6 (5.2) months. INTERVENTIONS Dapagliflozin, 10 mg, once daily vs placebo in addition to standard therapy. MAIN OUTCOMES AND MEASURES The primary composite outcome was time to first hospitalization for heart failure, urgent heart failure visit requiring intravenous therapy, or cardiovascular death. The trial results were extrapolated to estimate the projected long-term treatment effects of dapagliflozin over the duration of a patient's lifetime for the primary outcome and the secondary outcome of death from any cause. RESULTS A total of 4744 patients (1109 women [23.4%]; 3635 men [76.6%]) were randomized in DAPA-HF, with a mean (SD) age of 66.3 (10.9) years. The extrapolated mean event-free survival for an individual aged 65 years from a primary composite end point event was 6.2 years for placebo and 8.3 years for dapagliflozin, representing an event-free survival time gain of 2.1 years (95% CI, 0.8-3.3 years; P = .002). When considering death from any cause, mean extrapolated life expectancy for an individual aged 65 years was 9.1 years for placebo and 10.8 years for dapagliflozin, with a gain in survival of 1.7 years (95% CI, 0.1-3.3; P = .03) with dapagliflozin. Similar results were seen when extrapolated across the age range studied. In analyses of subgroups of patients in DAPA-HF, consistent benefits were seen with dapagliflozin on both event-free and overall survival. CONCLUSIONS AND RELEVANCE These findings indicate that dapagliflozin provides clinically meaningful gains in extrapolated event-free and overall survival. These findings may be helpful in communicating the benefits of this treatment to patients with HFrEF. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03036124.

Abstract
IMPORTANCE Women may respond differently to certain treatments for heart failure (HF) with reduced ejection fraction (HFrEF) than men. OBJECTIVE To investigate the efficacy and safety of dapagliflozin compared with placebo in men and women with HFrEF enrolled in the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure trial (DAPA-HF). DESIGN, SETTING, AND PARTICIPANTS Prespecified subgroup analysis of a phase 3 randomized clinical trial conducted at 410 sites in 20 countries. Patients with New York Heart Association functional class II through IV with an ejection fraction of 40% or less and elevated N-terminal pro-B-type natriuretic peptide were eligible. Data were analyzed between June 2020 and January 2021. INTERVENTIONS Addition of once-daily 10 mg of dapagliflozin or placebo to guideline-recommended therapy. MAIN OUTCOMES AND MEASURES The primary outcome was the composite of an episode of worsening HF (HF hospitalization or urgent HF visit requiring intravenous therapy) or cardiovascular death. RESULTS A total of 4744 patients were randomized in DAPA-HF, of whom 1109 were women (23.4%). Compared with placebo, dapagliflozin reduced the risk of worsening HF events or cardiovascular death to a similar extent in both men and women (hazard ratios, 0.73 [95% CI, 0.63-0.85] and 0.79 [95% CI, 0.59-1.06], respectively; P for interaction = .67). Consistent benefits were observed for the components of the primary outcome and all-cause mortality. Compared with placebo, dapagliflozin increased the proportion of patients with a meaningful improvement in symptoms (Kansas City Cardiomyopathy Questionnaire total symptom score of ≥5 points; men, 59% vs 50%; women, 57% vs 54%; P for interaction = .14) and decreased the proportion with worsening symptoms (Kansas City Cardiomyopathy Questionnaire total symptom score decrease of ≥5 points; men, 25% vs 34%; women, 27% vs 31%; P for interaction = .15), irrespective of sex. Results were consistent for the Kansas City Cardiomyopathy Questionnaire clinical summary score and overall summary score. Study drug discontinuation and serious adverse events were not more frequent in the dapagliflozin group than in the placebo group in either men or women. CONCLUSIONS AND RELEVANCE Dapagliflozin reduced the risk of worsening HF, cardiovascular death, and all-cause death and improved symptoms, physical function, and health-related quality of life similarly in men and women with heart failure and reduced ejection fraction. In addition, dapagliflozin was safe and well-tolerated irrespective of sex. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03036124.

Abstract
Postprandial hypoglycemia is a disabling complication of the treatment of obesity by gastric bypass surgery. So far, no therapy exists, and the underlying mechanisms remain unclear. Here, we hypothesized that glucose-induced IL-1β leads to an exaggerated insulin response in this condition. Therefore, we conducted a placebo-controlled, randomized, double-blind, crossover study with the SGLT2-inhibitor empagliflozin and the IL-1 receptor antagonist anakinra (clinicaltrials.govNCT03200782; n = 12). Both drugs reduced postprandial insulin release and prevented hypoglycemia (symptomatic events requiring rescue glucose: placebo = 7/12, empagliflozin = 2/12, and anakinra = 2/12, pvallikelihood ratio test (LRT) = 0.013; nadir blood glucose for placebo = 2.4 mmol/L, 95% CI 2.18-2.62, empagliflozin = 2.69 mmol/L, 95% CI 2.31-3.08, and anakinra = 2.99 mmol/L, 95% CI 2.43-3.55, pvalLRT = 0.048). Moreover, analysis of monocytes ex vivo revealed a hyper-reactive inflammatory state that has features of an exaggerated response to a meal. Our study proposes a role for glucose-induced IL-1β in postprandial hypoglycemia after gastric bypass surgery and suggests that SGLT2-inhibitors and IL-1 antagonism may improve this condition.

Abstract
AIMS: To investigate predictors of the initial response of beta-hydroxybutyrate (BHB) and maximum BHB (max-BHB) values during long-term therapy with the sodium-glucose co-transporter-2 inhibitor tofogliflozin (TOFO), and to explore the association of the initial elevation of BHB with subsequent clinical effects in people with type 2 diabetes mellitus. METHODS We analysed 774 people receiving TOFO in phase 3 trials in two groups based on measurable BHB change at week 4 (initial response): the top quartile [n = 194] and the three lower quartiles [n = 579]. Multivariate analysis was used to determine baseline predictors of inclusion in the top quartile and the max-BHB values. To investigate the association of the initial response with subsequent clinical effects, adjusted changes in variables in the two groups were compared using an analysis of covariance model. RESULTS Of the participants, 66% were men, and the mean age, glycated haemoglobin, body mass index and estimated glomerular filtration rate were 58.5 years, 8.1%, 25.6 kg/m2 and 83.9 mL/min/1.73 m2 , respectively. Median changes in BHB at week 4 in the top quartile and lower three quartiles were +246.4* and +30.8* μmol/L, respectively (*P < .001 vs baseline). Lower baseline insulin secretion capacity predicted the inclusion in the top quartile and greater max-BHB levels. The top quartile was associated with greater weight loss following greater increases in free fatty acids and greater reductions in fasting C-peptide levels compared with the lower three quartiles. CONCLUSIONS Lower basal insulin secretion capacity might predict greater initial BHB elevations and max-BHB levels during long-term TOFO therapy. Greater weight loss through lipid use might be related to high initial BHB elevations.

Abstract
AIMS: EMPEROR-Preserved is an ongoing trial evaluating the effect of empagliflozin in patients with heart failure with preserved ejection fraction (HFpEF). This report describes the baseline characteristics of the EMPEROR-Preserved cohort and compares them with patients enrolled in prior HFpEF trials. METHODS AND RESULTS EMPEROR-Preserved is a phase III randomized, international, double-blind, parallel-group, placebo-controlled trial in which 5988 symptomatic HFpEF patients [left ventricular ejection fraction (LVEF) >40%] with and without type 2 diabetes mellitus (T2DM) have been enrolled. Patients were required to have elevated N-terminal pro B-type natriuretic peptide (NT-proBNP) concentrations (i.e. >300 pg/mL in patients without and >900 pg/mL in patients with atrial fibrillation) along with evidence of structural changes in the heart or documented history of heart failure hospitalization. Among patients enrolled from various regions (45% Europe, 11% Asia, 25% Latin America, 12% North America), the mean age was 72 ± 9 years, 45% were women. Almost all patients had New York Heart Association class II or III symptoms (99.6%), and 23% had prior heart failure hospitalization within 12 months. Thirty-three percent of the patients had baseline LVEF of 41-50%. The mean LVEF (54 ± 9%) was slightly lower while the median NT-proBNP [974 (499-1731) pg/mL] was higher compared with previous HFpEF trials. Presence of comorbidities such as diabetes (49%) and chronic kidney disease (50%) were common. The majority of the patients were on angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (80%) and beta-blockers (86%), and 37% of patients were on mineralocorticoid receptor antagonists. CONCLUSION When compared with prior trials in HFpEF, the EMPEROR-Preserved cohort has a somewhat higher burden of comorbidities, lower LVEF, higher median NT-proBNP and greater use of mineralocorticoid receptor antagonists at baseline. Results of the EMPEROR-Preserved trial will be available in 2021.

Abstract
AIMS/INTRODUCTION Tofogliflozin is a potent and highly selective sodium-glucose cotransporter 2 inhibitor that is currently used to treat patients with type 2 diabetes mellitus. The aim of the present study was to evaluate the safety and efficacy of tofogliflozin add-on to glucagon-like peptide-1 (GLP-1) receptor agonist monotherapy. MATERIALS AND METHODS In this 52-week, prospective, multicenter, single arm, post-marketing clinical study, Japanese patients who had already been receiving GLP-1 receptor agonist monotherapy for ≥8 weeks, glycated hemoglobin ≥7.0 and <10.5%, and body mass index ≥18.5 and <35.0 kg/m2 were enrolled. Tofogliflozin 20 mg was orally administered once daily for 52 weeks with GLP-1 receptor agonist. Primary end-points were safety and change in glycated hemoglobin from baseline to week 52. Safety was assessed on the basis of the adverse events. Changes from baseline in fasting plasma glucose, bodyweight, blood pressure, uric acid and lipid parameters were assessed as secondary efficacy end-points. RESULTS Of the 67 patients enrolled, 63 patients completed the study. Overall, 26 adverse drug reactions occurred in 17 patients (25.4%). Adverse drug reactions with a frequency of two or more patients (3.0%) were constipation, thirst, dehydration and pollakiuria. Hypoglycemia (n = 1) was limited. With the addition of tofogliflozin to GLP-1 receptor agonist, the subsequent mean (standard deviation) reduction in glycated hemoglobin was -0.6% (1.0%; P < 0.0001). Fasting plasma glucose, bodyweight and blood pressure were significantly improved. CONCLUSIONS Tofogliflozin add-on to GLP-1 receptor agonist monotherapy is an effective treatment option with an acceptable safety profile.

Abstract
In patients with type 2 diabetes mellitus (T2DM) and cardiovascular (CV) disease, empagliflozin (EMPA) decreased progression of chronic kidney disease (CKD), likely via a reduction in intraglomerular pressure. Due to prevalent comorbidities, such as hypertension and albuminuria, patients often receive other agents that alter intrarenal hemodynamics, including angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARBs), calcium channel blockers (CCBs) and diuretics. Nonsteroidal anti-inflammatory drugs (NSAIDs) may also be used by some individuals. In this exploratory, non-prespecified analysis, we investigated whether the kidney benefits of EMPA are altered in individuals already using the medications in these categories. In the BI 10773 (Empagliflozin) Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME®) trial, 7020 patients were essentially equally randomized to EMPA 10 mg, 25 mg or placebo added to their standard care. Differences in risk of incident or worsening nephropathy for pooled EMPA vs placebo across subgroups by baseline background medications (to which patients were not randomized) were assessed using a Cox proportional hazards model. Risk reductions in incident or worsening nephropathy with EMPA were consistent across medication subgroups, with no heterogeneity of treatment effect. As a representative example, the risk for acute renal failure was overall slightly increased in patients using ACEi/ARBs in all groups (placebo, EMPA 10 mg or EMPA 25 mg) but incidence rates were numerically lower in those assigned to EMPA. Similar patterns were observed for other medications included in this analysis. Thus, EMPA may assist to prevent CKD progression in patients with T2DM with CV disease, irrespective of common background medications that alter intrarenal hemodynamics, and without increasing acute renal adverse events.

Abstract
AIMS: Dapagliflozin is a selective inhibitor of sodium glucose co-transporter 2 (SGLT2). This study assessed the efficacy and safety of dapagliflozin 10 mg vs placebo in patients with type 2 diabetes (T2D) and moderate renal impairment (estimated glomerular filtration rate [eGFR], 45-59 mL/min/1.73 m2 ; chronic kidney disease [CKD] stage 3A). MATERIALS AND METHODS In this double-blind, parallel group, Phase 3 study (NCT02413398, clinicaltrials.gov) patients with inadequately controlled T2D (HbA1c 7.0%-11.0%) were randomized (1:1) to dapagliflozin 10 mg once daily (N = 160) or matching placebo (N = 161) for 24 weeks. Randomization was stratified by pre-enrolment glucose-lowering therapy. The primary endpoint was change from baseline in HbA1c at Week 24. RESULTS At Week 24, compared with placebo, dapagliflozin significantly decreased HbA1c (difference [95% CI], -0.34% [-0.53, -0.15]; P < 0.001), body weight (difference [95% CI], -1.25 kg [-1.90, -0.59]; P < 0.001), fasting plasma glucose (difference [95% CI], -0.9 mmol/L [-1.5, -0.4]; P = 0.001) and systolic blood pressure (difference [95% CI], -3.1 mm Hg [-6.3, 0.0]; P < 0.05). Decreases from baseline in eGFR were greater with dapagliflozin than placebo at Week 24 (-2.49 mL/min/1.73 m2 [-4.96, -0.02]), however, eGFR returned to baseline levels at Week 27 (3 weeks post-treatment) (0.61 mL/min/1.73 m2 [-1.59, 2.81]). No increase in adverse events (AEs; 41.9% vs 47.8%) or serious AEs (5.6% vs 8.7%) were reported with dapagliflozin versus placebo. No AEs of bone fractures, amputations or DKA were reported. CONCLUSIONS The findings of this study (NCT02413398, clinicaltrials.gov) support the positive benefit/risk profile of dapagliflozin for the treatment of patients with T2D and CKD 3A.
