Abstract
CONTEXT VERTIS CV evaluated the cardiovascular safety of ertugliflozin in patients with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD). OBJECTIVE The aim of these analyses was to assess the insulin requirements of VERTIS CV patients over the trial duration. METHODS Patients received ertugliflozin 5 mg, 15 mg, or placebo once daily; mean follow-up was 3.5 years. Time to insulin initiation in patients who were insulin naïve at baseline, change in insulin dose in patients receiving baseline insulin, and hypoglycemia incidence in both patient groups were assessed. RESULTS In VERTIS CV, mean duration of type 2 diabetes was 13.0 years; glycated hemoglobin was 8.2%. Among 4348 (53%) insulin-naïve patients, the likelihood of insulin initiation was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: hazard ratio [HR] 0.70, 95% CI 0.58-0.84; ertugliflozin 15 mg: HR 0.64, 95% CI 0.53-0.78). Time to insulin initiation was delayed with ertugliflozin; the estimated delay in reaching a 10% cumulative incidence of new insulin initiations vs placebo was 399 days with ertugliflozin 5 mg and 669 days with ertugliflozin 15 mg. Among 3898 (47%) patients receiving baseline insulin, the likelihood of requiring a ≥20% increase in insulin dose was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: HR 0.62, 95% CI 0.52-0.75; ertugliflozin 15 mg: HR 0.51, 95% CI 0.41-0.62). The incidence of hypoglycemia events was not increased with ertugliflozin treatment. CONCLUSION In VERTIS CV patients, ertugliflozin reduced the likelihood of insulin initiation, delayed the time to insulin initiation by up to ∼1.8 years, and reduced insulin dose requirements vs placebo, without increasing hypoglycemia events.

Abstract
INTRODUCTION Using data from the ertugliflozin cardiovascular outcomes trial in patients with type 2 diabetes mellitus (VERTIS CV; NCT01986881), associations between the initial estimated glomerular filtration rate (eGFR) "dip" with eGFR slope, glucosuria/natriuresis-related measures, and safety were investigated. METHODS Patients were categorized into tertiles based on change in eGFR at week 6: >+1.00 mL/min/1.73 m2 (tertile 1), >-5.99 and ≤+1.00 (tertile 2), and ≤-6.00 (tertile 3). eGFR slope after week 6 and week 18 was assessed by tertile. Glucosuria/natriuresis-related measures were also determined. Adverse events (AEs) were analyzed in the acute (baseline-week 6) and chronic periods (week 6-30 days after last dose of trial medication). RESULTS In the ertugliflozin group, chronic eGFR slopes (95% CI, mL/min/1.73 m2/year; weeks 6-156) were -0.76 (-1.03, -0.50), -0.29 (-0.51, -0.07), and -0.05 (-0.26, 0.17) in tertiles 1, 2, and 3, respectively (p value <0.001), and approximately -1.5 mL/min/1.73 m2/year across tertiles in the placebo group (p value = 0.79). At week 18, least squares mean (LSM) changes from baseline in glycated hemoglobin (%) were -0.77, -0.71, and -0.67 in tertiles 1, 2, and 3, respectively, in the ertugliflozin group; a similar tertile-associated trend was observed for uric acid. At week 18, LSM changes from baseline in hematocrit (%) were 2.07, 2.33, and 2.55 in tertiles 1, 2, and 3, respectively, in the ertugliflozin group; similar tertile-associated trends were observed for blood pressure. All pinteraction values were <0.0001 for glucosuria- and natriuresis-related measures. Kidney-related AEs were reported more frequently in tertiles 3 and 2 in the chronic period for both placebo- and ertugliflozin-treated groups. In both periods and in all tertiles, incidences of AEs did not differ between placebo- and ertugliflozin-treated groups. CONCLUSION With ertugliflozin, the tertile with the largest initial dip in eGFR had a slower rate of chronic eGFR decline. Initial eGFR changes were associated with changes in both glucosuria- and natriuresis-related measures.

Abstract
AIM: To evaluate the safety of efpeglenatide, a long-acting glucagon-like peptide-1 receptor agonist (GLP-1RA), and its effects on body weight management in adults without diabetes. MATERIALS AND METHODS In this phase II, randomized, placebo-controlled, double-blind trial, participants with a body mass index (BMI) ≥30 kg/m2 or ≥27 kg/m2 with comorbidity were randomized 1:1:1:1:1 to efpeglenatide (4 mg once weekly, 6 mg once weekly, 6 mg once every 2 wk, or 8 mg once every 2 wk; n = 237) or placebo (n = 60) in combination with a hypocaloric diet. The primary endpoint was body weight change from baseline after 20 wk of treatment, assessed using a mixed-effect model with repeated measures with an unstructured covariance matrix over all post-screening visits; treatment comparisons were based on least squares mean estimates. RESULTS Over 20 wk, all doses of efpeglenatide significantly reduced body weight from baseline versus placebo (P < 0.0001), with placebo-adjusted reductions ranging between -6.3 kg (6 mg once every 2 wk) and -7.2 kg (6 mg once weekly). Greater proportions of efpeglenatide-treated participants had body weight loss of ≥5% or ≥10% versus placebo (P < 0.01, all comparisons). Efpeglenatide led to significant improvements in glycaemic variables (fasting plasma glucose and glycated haemoglobin) and lipid profiles (cholesterol, triglycerides) versus placebo. Rates of study discontinuations as a result of adverse events ranged from 5% to 19% with efpeglenatide. Gastrointestinal effects were the most common treatment-emergent adverse events. CONCLUSIONS Efpeglenatide once weekly and once every 2 wk led to significant body weight reduction and improved glycaemic and lipid variables versus placebo. It was also well tolerated for weight management in adults without diabetes.

Abstract
AIMS: When treated with basal insulin peglispro (BIL), patients with type 1 diabetes mellitus (T1DM) exhibit weight loss and lower prandial insulin requirements versus insulin glargine (GL), while total insulin requirements remain similar. One possible explanation is enhanced lipid oxidation and improved ability to switch between glucose and lipid metabolism with BIL. This study compared the effects of BIL and GL on glucose and lipid metabolism in subjects with T1DM. MATERIALS AND METHODS Fifteen subjects with T1DM were enrolled into this open-label, randomised, crossover study, and received once-daily stable, individualised, subcutaneous doses of BIL and GL for 4 weeks each. Respiratory quotient (RQ) was measured using whole-room calorimetry, and energy expenditure (EE) and concentrations of ketone bodies (3-hydroxybutyrate) and acylcarnitines were assessed. RESULTS Mean sleep RQ was lower during the BIL (0.822) than the GL (0.846) treatment period, indicating greater lipid metabolism during the post-absorptive period with BIL. Increases in carbohydrate oxidation following breakfast were greater during BIL than GL treatment (mean change in RQ following breakfast 0.111 for BIL, 0.063 for GL). Furthermore, BIL treatment increased total daily EE versus GL (2215.9 kcal/d for BIL, 2135.5 kcal/d for GL). Concentrations of ketone bodies and acylcarnitines appeared to be higher following BIL than GL treatment. CONCLUSIONS BIL increased sleeping fat oxidation, EE, ketone bodies, acylcarnitines and post-prandial glucose metabolism when switching from conventional insulin, thus, restoring metabolic flexibility and increasing thermogenesis. These changes may explain the previously observed weight loss with BIL versus GL.

Abstract
OBJECTIVE Patients with type 2 diabetes have an increased risk of fragility fractures; the cause is unclear but is likely multifactorial. Some diabetes treatments induce bone loss, accentuating underlying skeletal fragility and increasing fracture risk. This subgroup analysis aimed to compare long-term effects of liraglutide and glimepiride on bone mineral density (BMD) in patients with type 2 diabetes. METHODS LEAD-3, a 52-week, double-blind, active-control, phase III, multicenter trial, investigated the efficacy of liraglutide (1.2 and 1.8 mg/day) versus glimepiride monotherapy in type 2 diabetes. A 52-week, open-label extension followed, in which participants remained on randomized therapy. A subgroup of participants underwent BMD measurement by dual-energy X-ray absorptiometry at baseline, 52, and 104 weeks. The main outcome measure was change from baseline in total body BMD at 52 and 104 weeks, assessed by analysis of covariance. RESULTS A total of 746 patients with type 2 diabetes aged 19 to 79 years were randomized into the main trial. Of these, 61 patients (20 assigned to liraglutide 1.8 mg/day, 23 to liraglutide 1.2 mg/day, 18 to glimepiride 8 mg/day) had BMD measurements. Baseline age, body mass index, diabetes duration, glycated hemoglobin, and total BMD were similar across treatment groups. There was no apparent difference in mean total BMD change from baseline in patients receiving liraglutide 1.8 or 1.2 mg/day or glimepiride 8 mg/day at 52 or 104 weeks. CONCLUSION In this small subgroup analysis, liraglutide monotherapy did not negatively affect total BMD in a 2-year prospective study, suggesting it may not exacerbate the consequences of bone fragility.

Abstract
AIM: To evaluate the efficacy and safety of the dipeptidyl peptidase-4 inhibitor alogliptin plus metformin (A + M) initial combination therapy versus either as monotherapy in drug-naïve T2DM patients. METHODS This international, randomized, double-blind, placebo-controlled, 26-week study involved T2DM patients with hyperglycaemia (HbA1c 7.5-10.0%) following diet/exercise therapy. Patients (N = 784) received placebo, alogliptin (A, 12.5 mg BID or 25 mg QD), metformin (M, 500 or 1000 mg BID) or A + M (12.5/500 or 12.5/1000 mg BID); placebo, A25 for secondary analyses only. ENDPOINTS week 26 changes from baseline in HbA1c (primary), fasting plasma glucose (FPG) and 2-h postprandial glucose (PPG); incidences of clinical response and hyperglycaemic rescue. RESULTS Week 26 mean HbA1c reductions from baseline (8.45%) were -1.22 and -1.55% with A + M 12.5/500 and 12.5/1000 versus -0.56, -0.65, and -1.11% with A12.5, M500 and M1000 (p<0.001, A + M vs. component monotherapies). FPG reductions were -1.76 and -2.55 mmol/L with 12.5/500 and 12.5/1000 versus -0.54, -0.64 and -1.78 mmol/L with A12.5, M500 and M1000 (p < 0.05, A + M vs. component monotherapies). Significantly more A + M-treated patients achieved HbA1c < 7% (47.1-59.5% vs. 20.2-34.3% with monotherapy), significantly fewer required hyperglycaemic rescue (2.6-12.3% vs. 10.8-22.9% with monotherapy). A + M caused only mild/moderate hypoglycaemia (1.9-5.3%) and weight loss (0.6-1.2 kg). CONCLUSIONS Alogliptin plus metformin initial combination therapy was well tolerated yet more efficacious in controlling glycaemia in drug-naïve T2DM patients than either as monotherapy.
