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-proBNPvsplacebo (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%)vsplacebo (-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)vsplacebo (-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.
