Effects of Liraglutide Compared With Placebo on Events of Acute Gallbladder or Biliary Disease in Patients With Type 2 Diabetes at High Risk for Cardiovascular Events in the LEADER Randomized Trial.

ABSTRACT: OBJECTIVE:To explore gallbladder- and biliary tract-related events reported for the liraglutide and placebo groups in the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) trial. RESEARCH DESIGN AND METHODS:LEADER was an international, randomized, double-blind, controlled cardiovascular (CV) outcomes trial. Participants with type 2 diabetes at high risk for CV events (n = 9,340) were randomized 1:1 to receive either liraglutide (?1.8 mg daily; n = 4,668) or placebo (n = 4,672), with both groups also receiving standard care (treatment period: 3.5-5 years). Acute gallstone disease was a medical event of special interest. This post hoc analysis categorized captured events of acute gallbladder or biliary disease into four groups: uncomplicated gallbladder stones, complicated gallbladder stones, cholecystitis, and biliary obstruction. Time to first event by treatment group was analyzed using Cox regression. RESULTS:There was an increased risk of acute gallbladder or biliary disease with liraglutide versus placebo (n = 141 of 4,668 vs. n = 88 of 4,672 patients, respectively; hazard ratio [HR] 1.60; 95% CI 1.23, 2.09; P < 0.001). Similar trends were observed for each of the four categories of gallbladder- or biliary tract-related events. Cholecystectomy was performed more frequently in liraglutide-treated patients (HR 1.56; 95% CI 1.10, 2.20; P = 0.013) but for similar proportions of the patients who experienced gallbladder- or biliary tract-related events (57% with liraglutide vs. 59% with placebo). CONCLUSIONS:Although LEADER was not specifically designed to assess acute gallbladder or biliary disease, the trial showed an increased risk of gallbladder- or biliary tract-related events with liraglutide versus placebo, which appeared to be consistent across four categories of these events. Further studies should investigate the relevant mechanisms.

Project description:Background In cardiovascular outcome trials, the sodium glucose cotransporter 2 inhibitor empagliflozin and glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide caused similar reductions in major adverse cardiac events (MACE). We compared clinical outcomes in routine clinical care. Methods and Results EMPLACE (Cardiovascular and Renal Outcomes, and Mortality in Danish Patients with Type 2 Diabetes Who Initiate Empagliflozin Versus GLP-1RA: A Danish Nationwide Comparative Effectiveness Study) is an ongoing nationwide population-based comparative effectiveness cohort study in Denmark. For the present study, we included 14 498 new users of empagliflozin and 12 706 new users of liraglutide, 2015 to 2018. Co-primary outcomes were expanded major adverse cardiac events (stroke, myocardial infarction, unstable angina, coronary revascularization, hospitalization for heart failure [HHF], or all-cause death); HHF or all-cause death; and first HHF or first initiation of loop-diuretic therapy. Secondary outcomes included all-cause hospitalization or death. We applied propensity score balancing and Cox regression to compute adjusted hazard ratios (aHRs) in on-treatment (OT) and intention-to-treat (ITT) analyses. Cohorts were well balanced at baseline (median age 61 years, 59% men, diabetes mellitus duration 6.6 years, 30% with preexisting cardiovascular disease). During mean follow-up of 1.1 years in OT and 1.5 years in ITT analyses, empagliflozin versus liraglutide was associated with a similar rate of expanded major adverse cardiac events (OT aHR, 1.02; 95% CI, 0.91-1.14; ITT aHR, 1.06; 95% CI, 0.96-1.17), and HHF or all-cause death (OT aHR, 0.97; 95% CI, 0.85-1.11; ITT aHR, 1.02; 95% CI, 0.91-1.14); and a decreased rate of a first incident HHF or loop-diuretic initiation (OT aHR, 0.80; 95% CI, 0.68-0.94; ITT aHR, 0.87; 95% CI, 0.76-1.00), and of all-cause hospitalization or death (OT aHR, 0.93; 95% CI, 0.89-0.98; ITT aHR, 0.93; 95% CI, 0.90-0.97). Conclusions Empagliflozin and liraglutide initiators had comparable rates of expanded major adverse cardiac events, and HHF or all-cause death, whereas empagliflozin initiators had a lower rate of a first HHF or loop-diuretic initiation.

Project description:BACKGROUND:The cardiovascular effect of liraglutide, a glucagon-like peptide 1 analogue, when added to standard care in patients with type 2 diabetes, remains unknown. METHODS:In this double-blind trial, we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo. The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome, with a margin of 1.30 for the upper boundary of the 95% confidence interval of the hazard ratio. No adjustments for multiplicity were performed for the prespecified exploratory outcomes. RESULTS:A total of 9340 patients underwent randomization. The median follow-up was 3.8 years. The primary outcome occurred in significantly fewer patients in the liraglutide group (608 of 4668 patients [13.0%]) than in the placebo group (694 of 4672 [14.9%]) (hazard ratio, 0.87; 95% confidence interval [CI], 0.78 to 0.97; P<0.001 for noninferiority; P=0.01 for superiority). Fewer patients died from cardiovascular causes in the liraglutide group (219 patients [4.7%]) than in the placebo group (278 [6.0%]) (hazard ratio, 0.78; 95% CI, 0.66 to 0.93; P=0.007). The rate of death from any cause was lower in the liraglutide group (381 patients [8.2%]) than in the placebo group (447 [9.6%]) (hazard ratio, 0.85; 95% CI, 0.74 to 0.97; P=0.02). The rates of nonfatal myocardial infarction, nonfatal stroke, and hospitalization for heart failure were nonsignificantly lower in the liraglutide group than in the placebo group. The most common adverse events leading to the discontinuation of liraglutide were gastrointestinal events. The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group. CONCLUSIONS:In the time-to-event analysis, the rate of the first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo.
