Elevated levels of non-esterified fatty acids (NEFA) play a role in insulin resistance, impaired beta-cell function and they are a denominator of the abnormal atherogenic lipid profile that characterizes obese patients with type 2 diabetes (T2DM). We hypothesized that the GLP-1 receptor agonist liraglutide, in combination with metformin, would reduce lipolysis. In a randomized, double-blind, placebo-controlled, cross-over trial, 41 T2DM patients with coronary artery disease were randomized and treated with liraglutide-metformin vs placebo-metformin during 12- + 12-week periods with a wash-out period of at least 2 weeks before and between the intervention periods. NEFA kinetics were estimated using the Boston Minimal Model of NEFA metabolism, with plasma NEFA and glucose levels measured during a standard 180-minute frequently sampled intravenous glucose tolerance test. Liraglutide-metformin reduced estimates of lipolysis. Furthermore, placebo-metformin increased estimates of lipid oxidation, while treatment with liraglutide eliminated this effect. We conclude that liraglutide exerts a clinically relevant reduction in estimates of lipolysis and lipid oxidation which is explained, in part, by improved insulin secretion, as revealed by an intravenous glucose tolerance test.  相似文献

Aim

Liraglutide treatment is associated with gallbladder-related disorders and has been shown to delay postprandial gallbladder refilling. The gut hormones cholecystokinin (CCK), fibroblast growth factor 19 (FGF19) and glucagon-like peptide 2 (GLP-2), are known to regulate gallbladder motility and may be implicated in gallbladder-related disorders associated with liraglutide treatment.

Materials and Methods

In a double-blind, 12-week trial, 52 participants [50% male, age 47.6 ± 10.0 years, body mass index 32.6 ± 3.4 kg/m2 (mean ± standard deviation)] with obesity were randomized 1:1 to once-daily subcutaneous liraglutide (escalated from 0.6 mg to 3.0 mg once-daily) or placebo. During liquid meal tests performed at baseline, after the first dose and following 12 weeks of treatment, we evaluated postprandial gallbladder dynamics and plasma responses of CCK, FGF19 and GLP-2.

Results

Liraglutide reduced postprandial FGF19 after the first dose [area under the curve (AUC)0-240 min 24.8 vs. 48.0 min × ng/ml, treatment ratio (TR) (95% confidence interval) 0.52 (0.39; 0.69)] and following 12 weeks of treatment [AUC0-240 min 33.7 vs. 48.5 ng/ml × min, TR 0.69 (0.52; 0.93)]. Liraglutide also reduced postprandial GLP-2 responses (AUC0-240 min 3650 vs. 4894 min × pmol/L, TR 0.75 (0.62; 0.90)] following the first dose as well as after 12 weeks [AUC0-240 min 3760 vs. 4882 min × pmol/L, TR 0.77 (0.60; 0.99)]. Liraglutide increased postprandial responses of CCK after the first dose [AUC0-240 min 762 vs. 670 min × pmol/L; TR 1.14 (0.97; 1.33)] and following 12 weeks of treatment [AUC0-240 min 873 vs. 628 min × pmol/L; TR 1.39 (1.12; 1.73)].

Conclusion

Compared with placebo, treatment with liraglutide decreased postprandial FGF19 and GLP-2 concentrations and increased postprandial CCK concentrations, which may explain the delayed postprandial gallbladder refilling observed in individuals with obesity treated with liraglutide.  相似文献

We assessed the effects of liraglutide treatment on five cardiovascular risk biomarkers, reflecting different pathophysiology: tumour necrosis factor (TNF)‐α; soluble urokinase plasminogen activator receptor (suPAR); mid‐regional pro‐adrenomedullin (MR‐proADM); mid‐regional pro‐atrial natriuretic peptide (MR‐proANP); and copeptin, in people with type 2 diabetes with albuminuria. In a randomized, double‐blind, placebo‐controlled, crossover trial we enrolled people with type 2 diabetes and persistent albuminuria (urinary albumin‐to‐creatinine ratio [UACR] >30 mg/g) and estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2. Participants received liraglutide (1.8 mg/d) and matched placebo for 12 weeks, in random order. The primary endpoint was change in albuminuria; this was a prespecified sub‐study. A total of 32 participants were randomized, of whom 27 completed the study. TNF‐α level was 12% (95% confidence interval [CI] 3; 20) lower after liraglutide treatment compared with placebo (P = .012); MR‐proADM level was 4% (95% CI 0; 8) lower after liraglutide treatment compared with placebo (P = .038), and MR‐proANP level was 13% (95% CI 4; 21) lower after liraglutide treatment compared with placebo (P = .006). In the present study, we showed anti‐inflammatory effects of liraglutide treatment, reflected in reductions in levels of TNF‐α and MR‐proADM, while the reduction in MR‐proANP levels may represent a clinically relevant benefit with regard to heart failure.  相似文献

The efficacy and safety of liraglutide 3.0 mg versus placebo, as adjunct to diet and exercise, was evaluated in racial subgroups. This post hoc analysis of pooled data from five double‐blind randomized, placebo‐controlled trials was conducted in 5325 adults with either a body mass index (BMI) ≥27 kg/m2 plus ≥1 comorbidity or a BMI ≥30 kg/m2. Statistical interaction tests evaluated possible treatment effect differences between racial subgroups: white (4496, 84.4%), black/African‐American (550, 10.3%), Asian (168, 3.2%) and other (111, 2.1%). Effects of liraglutide 3.0 mg on weight loss, associated metabolic effects and safety profile were generally consistent across racial subgroups. All achieved statistically significant mean weight loss at end‐of‐treatment with liraglutide 3.0 mg versus placebo: white 7.7% versus 2.3%, black/African‐American 6.3% versus 1.4%, Asian 6.3% versus 2.5%, other 7.3% versus 0.49%. Treatment effects on weight and cardiovascular risk markers generally showed no dependence on race (interaction test p > 0.05). Adverse events were similar across racial subgroups.  相似文献

Aim

To report a Phase I study of subcutaneous glucagon receptor (GCGR)/glucagon-like peptide-1 receptor (GLP-1R) dual agonist BI 456906 versus placebo in healthy Japanese men with overweight/obesity.

Materials and methods

We investigated multiple rising doses of BI 456906 escalated over 16 weeks (maximum doses: 1.8 mg once weekly [dose group {DG} 1], 4.8 mg once weekly [DG 2] and 2.4 mg twice weekly [DG 3]) in Japanese men with a body mass index of 23 to 40 kg/m2.

Results

Thirty-six participants were treated (n = 9 per DG and placebo). Overall, 10 participants (37.0%) treated with BI 456906 withdrew from dose escalation due to adverse events (amylase increase, n = 1; decreased appetite, n = 9), and the proportion of participants was higher in DG 2 (n = 6, 66.7%) versus DGs 1 and 3 (both n = 2, 22.2%). No participants receiving placebo withdrew from dose escalation. BI 456906 exposure increased with dose and dose escalation in each DG. Treatment with BI 456906 decreased placebo-corrected bodyweight after 16 weeks (placebo +1.06%): DG 1, −5.57%; DG 2, −12.37%; DG 3, −9.62%. Paracetamol absorption decreased in Week 1 for DGs 2 and 3, indicating transient delayed gastric emptying. BI 456906 reduced plasma alanine and glucagon levels, indicating indirect target engagement at GCGRs and GLP-1Rs. Drug-related adverse events were reported for all participants receiving BI 456906 and four receiving placebo, the most frequent being decreased appetite (n = 24, 66.7%).

Conclusions

BI 456906 showed no unexpected tolerability concerns and it reduced placebo-corrected bodyweight by up to 12.37% in Japanese men with overweight/obesity after 16 weeks of treatment.  相似文献

This double-blind, randomized, single-site, crossover trial compared the injection-site experience with the starting doses of semaglutide and dulaglutide. Healthy subjects (aged 18–75 years; body mass index ≥ 25 kg/m2; n = 104) were randomized 1:1, using a pregenerated list, to semaglutide 0.25 mg as the first injection and dulaglutide 0.75 mg as the second injection or vice versa; each was administered using their proprietary pen-injectors, according to instructions for use. The primary endpoint was intensity of injection-site pain, measured using a visual analogue scale (VAS; 0 mm = no pain, 100 mm = unbearable pain). Exploratory endpoints included intensity category, duration and quality of injection-site pain, and comparative assessment of injection-site pain with the two injections. The point estimate of the VAS score for injection-site pain intensity was 11.5 mm with dulaglutide versus 5.6 mm with semaglutide; mean (95% confidence interval) estimated treatment difference 5.9 (3.6; 8.2) mm; p < .0001. Other endpoints corroborated a less painful injection experience with semaglutide versus dulaglutide. Safety was consistent with reported data for the drugs. In conclusion, the injection-site experience with semaglutide was rated as less painful than that with dulaglutide.  相似文献

The AWARD-11 trial demonstrated the safety and efficacy of dulaglutide 3.0 and 4.5 mg compared to dulaglutide 1.5 mg in patients with type 2 diabetes inadequately controlled with metformin. This post hoc analysis examined the change from baseline in glycated haemoglobin (HbA1c) and proportions of patients achieving HbA1c <7% at weeks 36 and 52 with dulaglutide 1.5 mg, 3.0 mg or 4.5 mg across clinically relevant baseline HbA1c subgroups (<8%; 8.0% to < 9.0%; 9.0% to < 10%; and ≥ 10%). Mean reductions in HbA1c were observed across all baseline HbA1c subgroups at 36 weeks (range of HbA1c change: 1.5 mg: −1.0% to −2.2%; 3.0 mg: −1.2% to −2.5%; and 4.5 mg: −1.2% to −3.2%). More patients randomized to 3.0 mg or 4.5 mg (vs. 1.5 mg) achieved HbA1c <7% at 36 weeks regardless of baseline HbA1c; the difference in proportions was greater at higher baseline HbA1c (P-interaction = 0.096). Similar patterns in glycaemic improvement and proportions achieving HbA1c <7% were observed at 52 weeks. Hypoglycaemia and gastrointestinal adverse events were similar among the HbA1c subgroups. Glycaemic control was improved with dulaglutide dose escalation from 1.5 mg to 3.0 mg or 4.5 mg across baseline HbA1c subgroups (<8%; 8.0% to < 9.0%; 9.0% to < 10%; and ≥ 10%).  相似文献
