Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.

The Impact of Chronic Heart Failure Treatment on Glycemic Variability in Patients without Diabetes Mellitus

Background. According to statistics, about 26 million people worldwide suffer from heart failure (HF). Currently, sodium-glucose cotransporter 2 inhibitors are widely prescribed for treatment of HF with reduced left ventricular ejec-tion fraction (LVEF) throughout the world. Therefore, prescribing drugs that have anti-hypoglycemic effect in patients without diabetes mellitus still raises some concerns, considering the possible risk of developing hypoglycemia. The aim. To assess the effect of dapagliflozin on glycemic variability in treatment of HF with reduced LVEF in patients without diabetes mellitus. Materials and methods. The study was conducted at the premises of the Department of Cardiometabolic Diseases of the Ukrainian Children’s Cardiac Center. Twenty-three patients with HF with reduced LVEF of various etiologies without diabetes mellitus were evaluated. The variability of glycemia in the study group was assessed using continuous glucose monitoring. For this, the MiniMed iPro2 continuous glucose monitoring system (Medtronic, USA) was used. The sensor was inserted on day 1 and removed on day 7. Average value of glycemia during the day, time in range (TIR) and time below range (TBR) were calculated on the basis of data about the level of glucose in the intercellular fluid obtained for 6 days of monitoring. Dapagliflozin 10 mg once a day was prescribed to all the patients included in the study for the treatment of HF with reduced LVEF. The average follow-up period was 7 months. Results. The examined patients were divided according to clinical and laboratory characteristics. Assessment of daily variability of glycemia during 6 days of observation using continuous glucose monitoring in patients on dapagliflozin revealed average blood glucose level from 4.4 mmol/L (minimum value) to 6.0 mmol/L (maximum value). These results indicate minimal risk of hypoglycemia and safety of using dapagliflozin in case of HF with reduced LVEF without concomi-tant type 2 diabetes mellitus. TIR and TBR indicators were also evaluated in patients with and without prediabetes. The obtained data allows to assert the same safety of taking dapagliflozin in both these groups, due to the fact that time of glycemia <3.9 mmol/l does not exceed the indicator of 5%. Conclusion. The use of dapagliflozin as part of complex therapy of HF with reduced LVEF does not elevate the risk of developing hypoglycemia in patients without diabetes mellitus

Anti-interleukin-21 antibody and liraglutide for the preservation of β-cell function in adults with recent-onset type 1 diabetes: a randomised, double-blind, placebo-controlled, phase 2 trial

BACKGROUND: Type 1 diabetes is characterised by progressive loss of functional beta-cell mass, necessitating insulin treatment. We aimed to investigate the hypothesis that combining anti-interleukin (IL)-21 antibody (for low-grade and transient immunomodulation) with liraglutide (to improve beta-cell function) could enable beta-cell survival with a reduced risk of complications compared with traditional immunomodulation.METHODS: This randomised, parallel-group, placebo-controlled, double-dummy, double-blind, phase 2 trial was done at 94 sites (university hospitals and medical centres) in 17 countries. Eligible participants were adults aged 18-45 years with recently diagnosed type 1 diabetes and residual beta-cell function. Individuals with unstable type 1 diabetes (defined by an episode of severe diabetic ketoacidosis within 2 weeks of enrolment) or active or latent chronic infections were excluded. Participants were randomly assigned (1:1:1:1), with stratification by baseline stimulated peak C-peptide concentration (mixed-meal tolerance test [MMTT]), to the combination of anti-IL-21 and liraglutide, anti-IL-21 alone, liraglutide alone, or placebo, all as an adjunct to insulin. Investigators, participants, and funder personnel were masked throughout the treatment period. The primary outcome was the change in MMTT-stimulated C-peptide concentration at week 54 (end of treatment) relative to baseline, measured via the area under the concentration-time curve (AUC) over a 4 h period for the full analysis set (intention-to-treat population consisting of all participants who were randomly assigned). After treatment cessation, participants were followed up for an additional 26-week off-treatment observation period. This trial is registered with ClinicalTrials.gov, NCT02443155.FINDINGS: Between Nov 10, 2015, and Feb 27, 2019, 553 adults were assessed for eligibility, of whom 308 were randomly assigned to receive either anti-IL-21 plus liraglutide, anti-IL-21, liraglutide, or placebo (77 assigned to each group). Compared with placebo (ratio to baseline 0·61, 39% decrease), the decrease in MMTT-stimulated C-peptide concentration from baseline to week 54 was significantly smaller with combination treatment (0·90, 10% decrease; estimated treatment ratio 1·48, 95% CI 1·16-1·89; p=0·0017), but not with anti-IL-21 alone (1·23, 0·97-1·57; p=0·093) or liraglutide alone (1·12, 0·87-1·42; p=0·38). Despite greater insulin use in the placebo group, the decrease in HbA1c (a key secondary outcome) at week 54 was greater with all active treatments (-0·50 percentage points) than with placebo (-0·10 percentage points), although the differences versus placebo were not significant. The effects diminished upon treatment cessation. Changes in immune cell subsets across groups were transient and mild (&lt;10% change over time). The most frequently reported adverse events included gastrointestinal disorders, in keeping with the known side-effect profile of liraglutide. The rate of hypoglycaemic events did not differ significantly between active treatment groups and placebo, with an exception of a lower rate in the liraglutide group than in the placebo group during the treatment period. No events of diabetic ketoacidosis were observed. One participant died while on liraglutide (considered unlikely to be related to trial treatment) in connection with three reported adverse events (hypoglycaemic coma, pneumonia, and brain oedema).INTERPRETATION: The combination of anti-IL-21 and liraglutide could preserve beta-cell function in recently diagnosed type 1 diabetes. The efficacy of this combination appears to be similar to that seen in trials of other disease-modifying interventions in type 1 diabetes, but with a seemingly better safety profile. Efficacy and safety should be further evaluated in a phase 3 trial programme.FUNDING: Novo Nordisk
