Aims To evaluate the effects of the sodium glucose cotransporter 2 ( SGLT2) inhibitor empagliflozin added to metformin for 12 weeks in patients with type 2 diabetes. Methods This dose-ranging, double-blind, placebo-controlled trial randomized 495 participants with type 2 diabetes inadequately controlled on metformin [haemoglobin A1c ( HbA1c) >7 to ≤10%] to receive 1, 5, 10, 25, or 50 mg empagliflozin once daily ( QD), or placebo, or open-label sitagliptin (100 mg QD), added to metformin for 12 weeks. The primary endpoint was change in HbA1c from baseline to week 12 (empagliflozin groups versus placebo). Results Reductions in HbA1c of −0.09 to −0.56% were observed with empagliflozin after 12 weeks, versus an increase of 0.15% with placebo (baseline: 7.8-8.1%). Compared with placebo, empagliflozin doses from 5 to 50 mg resulted in reductions in fasting plasma glucose (−2 to −28 mg/ dl vs. 5 mg/ dl with placebo; p < 0.0001) and body weight (−2.3 to −2.9 kg vs. −1.2 kg; p < 0.01). Frequency of adverse events was generally similar with empagliflozin (29.6-48.6%), placebo (36.6%) and sitagliptin (35.2%). Hypoglycaemia rates were very low and balanced among groups. Most frequent adverse events with empagliflozin were urinary tract infections (4.0% vs. 2.8% with placebo) and pollakiuria (2.5% vs. 1.4% with placebo). Genital infections were reported only with empagliflozin (4.0%). Conclusions Once daily empagliflozin as add-on therapy to metformin was well tolerated except for increased genital infections and resulted in reductions in HbA1c, fasting plasma glucose and body weight in patients with type 2 diabetes inadequately controlled on metformin monotherapy.

Aim This Phase IIb, randomized, double-blind, placebo-controlled trial evaluated the efficacy, safety, tolerability and pharmacokinetics of empagliflozin in patients with type 2 diabetes. Methods Four hundred and eight patients (treatment-naïve or after a 4-week wash-out period) were randomized to receive empagliflozin 5, 10 or 25 mg once daily, placebo or open-label metformin for 12 weeks. The primary endpoint was change in haemoglobin A1c ( HbA1c) after 12 weeks. Results After 12 weeks' treatment, empagliflozin showed dose-dependent reductions in HbA1c from baseline [5 mg: −0.4%, 10 mg: −0.5%, 25 mg: −0.6%; all doses p < 0.0001 vs. placebo (+0.09%)]. Fasting plasma glucose ( FPG) decreased with empagliflozin [5 mg: −1.29 mmol/l, 10 mg: −1.61 mmol/l, 25 mg: −1.72 mmol/l; all doses p < 0.0001 vs. placebo (+0.04 mmol/l)]. Body weight decreased in all empagliflozin groups (all doses p < 0.001 vs. placebo). The incidence of adverse events ( AEs) was similar in the placebo (32.9%) and empagliflozin (29.1%) groups. The most frequently reported AEs on empagliflozin were pollakiuria (3.3% vs. 0% for placebo), thirst (3.3% vs. 0% for placebo) and nasopharyngitis (2.0% vs. 1.2% for placebo). AEs consistent with urinary tract infections ( UTIs) were reported in four (1.6%) patients on empagliflozin vs. one (1.2%) on placebo. Genital infections were reported in five (2%) patients on empagliflozin vs. 0% on placebo. No UTIs or genital infections led to premature discontinuation. Conclusions In patients with type 2 diabetes, empagliflozin resulted in dose-dependent, clinically meaningful reductions in HbA1c and FPG, and reductions in body weight compared with placebo. Empagliflozin was well-tolerated with a favourable safety profile. [ABSTRACT FROM AUTHOR]

ABSTRACT Aim To investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of empagliflozin in patients with type 2 diabetes following oral administration of 10, 25 or 100 mg doses once daily over 28 days. Methods A total of 78 patients were assigned to empagliflozin 10 mg (n = 16), 25 mg (n = 16) or 100 mg (n = 30) or placebo (n = 16) for 28 days. Assessments included adverse events ( AEs) and pharmacokinetic and pharmacodynamic endpoints. Results Empagliflozin exposure increased dose-proportionally over the dose range 10-100 mg and showed linear pharmacokinetics with respect to time. Urinary glucose excretion ( UGE) increased from baseline to day 1 by 74, 90 and 81 g with empagliflozin 10, 25 and 100 mg, respectively. The increases in UGE were maintained over 28 days with multiple dosing. Virtually no change in UGE was observed in the placebo group. Significant reductions from baseline in mean daily plasma glucose and fasting plasma glucose were observed with empagliflozin compared with placebo. The incidence of AEs was similar in the empagliflozin and placebo groups (50.0, 56.3 and 66.7% with empagliflozin rising doses and 62.5% with placebo). The most frequently reported AEs were pollakiuria (10.3%), nasopharyngitis (9.0%), constipation (9.0%) and headache (7.7%). Conclusions Oral administration of empagliflozin at doses of 10, 25 or 100 mg once daily over 28 days resulted in significant increases in UGE and reductions in blood glucose compared with placebo, and were well tolerated in patients with type 2 diabetes.

Aim To assess the effect of empagliflozin on cardiovascular ( CV) risk in patients with type 2 diabetes ( T2DM) through a meta-analysis of data from eight placebo-controlled trials. Methods Data were analysed from eight randomized placebo-controlled trials undertaken to investigate the efficacy and safety of empagliflozin 10 and 25 mg once daily in patients with T2DM, comprising patients at low/medium and high CV risk. Suspected CV events were prospectively adjudicated. The empagliflozin 10 and 25 mg groups were pooled for the primary analysis. The primary endpoint was a composite of CV death, non-fatal myocardial infarction ( MI), non-fatal stroke and hospitalization for unstable angina [4-point major adverse CV events ( MACE)]. The secondary endpoint was a composite of CV death, non-fatal MI and non-fatal stroke (3-point MACE). Risk estimates were calculated using Cox regression analysis. Results A total of 3835 patients received placebo and 7457 received empagliflozin. Total exposure was 7448.3 years for placebo and 15482.1 years for empagliflozin. Four-point MACE occurred in 365 (9.5%) patients receiving placebo and 635 (8.5%) patients receiving empagliflozin [hazard ratio for empagliflozin vs. placebo 0.86 (95% CI 0.76, 0.98)]. Three-point MACE occurred in 307 (8.0%) patients receiving placebo and 522 (7.0%) patients receiving empagliflozin [hazard ratio for empagliflozin vs. placebo 0.84 (95% CI 0.73, 0.96)]. Conclusions In a meta-analysis of data from eight randomized trials involving 11 292 patients with T2DM at low/medium or high CV risk, empagliflozin was associated with a reduced risk of 4-point MACE and 3-point MACE compared with placebo.
