Effects of the dual sodium-glucose linked transporter inhibitor, licogliflozin vs placebo or empagliflozin in patients with type 2 diabetes and heart failure.

ABSTRACT: AIMS:Explore the efficacy, safety and tolerability of the dual sodium-glucose cotransporter (SGLT) 1 and 2 inhibitor, licogliflozin in patients with type-2 diabetes mellitus (T2DM) and heart failure. METHODS:This multicentre, parallel-group phase IIA study randomized 125 patients with T2DM and heart failure (New York Heart Association II-IV; plasma N-terminal pro b-type natriuretic peptide [NT-proBNP] >300 pg/mL) to licogliflozin (2.5 mg, 10 mg, 50 mg) taken at bedtime, empagliflozin (25 mg) or placebo (44 patients completed the study). The primary endpoint was change from baseline in NT-proBNP after 12 weeks. Secondary endpoints included change from baseline in glycated haemoglobin, fasting plasma glucose, weight, blood pressure, fasting lipid profile, high-sensitivity c-reactive protein, and safety and tolerability. RESULTS:Licogliflozin 10 mg for 12 weeks significantly reduced NT-proBNP vs placebo (Geometric mean ratio 0.56 [95% confidence interval: 0.33, 0.95], P = .033). A trend was observed with 50 mg licogliflozin (0.64 [95% confidence interval: 0.40, 1.03], P = .064), with no difference between licogliflozin and empagliflozin. The largest numerical decreases in glycated haemoglobin were with licogliflozin 50 mg (-0.58 ± 0.34%) and empagliflozin (-0.44 ± 1.18%) vs placebo (-0.04 ± 0.91%). The reduction in body weight was similar with licogliflozin 50 mg (-2.15 ± 2.40 kg) and empagliflozin (-2.25 ± 1.89 kg). A numerical reduction in systolic blood pressure was seen with licogliflozin 50 mg (-9.54 ± 16.88 mmHg) and empagliflozin (-6.98 ± 15.03 mmHg) vs placebo (-2.85 ± 11.97 mmHg). Adverse events (AEs) were mild, including hypotension (6.5%), hypoglycaemia (8.1%) and inadequate diabetes control (1.6%). The incidence of diarrhoea (4.9%) was lower than previously reported. CONCLUSION:The reduction in NT-proBNP with licogliflozin suggests a potential benefit of SGLT1 and 2 inhibition in patients with T2DM and heart failure.

Project description:Background We determined if the sodium glucose co-transporter 2 inhibitor empagliflozin attenuates pressure overload-induced heart failure in non-diabetic mellitus mice by direct cardiac effects and the mechanisms involved. Methods and Results Male C57BL/6J mice (4-6 months of age) were subjected to sham surgeries or transverse aortic constriction to produce cardiac pressure overload. Two weeks after transverse aortic constriction, empagliflozin (10 mg/kg per day) or vehicle was administered daily for 4 weeks. Empagliflozin increased survival rate and significantly attenuated adverse left ventricle remodeling and cardiac fibrosis after transverse aortic constriction. Empagliflozin also attenuated left ventricular systolic and diastolic dysfunction, evaluated by echocardiography, and increased exercise endurance by 36% in mice with transverse aortic constriction-induced heart failure. Empagliflozin significantly increased glucose and fatty acid oxidation in failing hearts, while reducing glycolysis. These beneficial cardiac effects of empagliflozin occurred despite no significant changes in fasting blood glucose, body weight, or daily urine volume. In vitro experiments in isolated cardiomyocytes indicated that empagliflozin had direct effects to improve cardiomyocyte contractility and calcium transients. Importantly, molecular docking analysis and isolated perfused heart experiments indicated that empagliflozin can bind cardiac glucose transporters to reduce glycolysis, restore activation of adenosine monophosphate-activated protein kinase and inhibit activation of the mammalian target of rapamycin complex 1 pathway. Conclusions Our study demonstrates that empagliflozin may directly bind glucose transporters to reduce glycolysis, rebalance coupling between glycolysis and oxidative phosphorylation, and regulate the adenosine monophosphate-activated protein kinase mammalian target of rapamycin complex 1 pathway to attenuate adverse cardiac remodeling and progression of heart failure induced by pressure-overload in non-diabetic mellitus mice.

Project description:AimsImpairment of vascular function contributes to the progression of chronic heart failure (HF) by increasing the afterload. Treatment with selective sodium-glucose cotransporter 2 (SGLT2) inhibitors improves the prognosis of HF, but the precise mechanisms remain unclear. The aim of this study was to analyse the effect of empagliflozin on vascular function in patients with HF.Methods and resultsIn an investigator initiated, double-blind, randomized, placebo-controlled, parallel-group, clinical study, patients with HF NYHA II-III and an ejection fraction of 49% or less were randomized 2:1 to receive empagliflozin 10 mg once daily or placebo for 3 months. A total of 74 patients (15% female), aged 66 ± 9 years, with a mean ejection fraction of 39 ± 8% and a median NTproBNP of 558 pg/mL (IQR 219-1051 pg/mL), were included. Vascular parameters such as central systolic blood pressure (cSBP), central pulse pressure (cPP), forward (FPH), and reflected pressure pulse height (RPH) decreased under resting conditions after 1 and 3 months (1 month: cSBP -6.4 ± 8.3 mmHg, P < 0.001, cPP -3.0 ± 6.6 mmHg, P = 0.004, FPH -2.5 ± 4.5 mmHg, P = 0.001, RPH -1.6 ± 3.0 mmHg, P = 0.001; 3 months: cSBP -4.6 ± 8.4 mmHg, P = 0.001, cPP -3.1 ± 4.8 mmHg, P < 0.001, FPH -1.7 ± 3.7 mmHg, P = 0.004, RPH -1.4 ± 2.5 mmHg, P = 0.001) in patients treated with empagliflozin (n = 45). In accordance, cSBP and cPP decreased in patients with empagliflozin treatment under 24 h ambulatory conditions after 1 and 3 months (1 month: cSBP -4.8 ± 10.1 mmHg, P = 0.003, cPP -2.0 ± 5.7 mmHg, P = 0.026; 3 months: cSBP -4.7 ± 9.0 mmHg, P = 0.002, cPP -2.1 ± 6.4 mmHg, P = 0.044). In the placebo group, there was no significant change after 1 and 3 months. The decrease in cSBP under resting conditions (-5.7 ± 2.4 mmHg, P = 0.019) after 1 month and in cSBP (-6.0 ± 2.6, P = 0.027) as well as in pulse wave velocity (-0.5 ± 0.2 m/s, P = 0.021) under 24 h ambulatory conditions after 3 months was greater in the empagliflozin group than in the placebo group.ConclusionsWe found an improvement of vascular function after treatment with empagliflozin that indicates decreased afterload of the left ventricle and may contribute to the beneficial effects of SGLT2 inhibition in HF.
