Efficacy and safety of liraglutide, a once-daily human glucagon-like peptide-1 analogue, in Latino/Hispanic patients with type 2 diabetes: post hoc analysis of data from four phase III trials

Abstract

The aim of the present analysis was to evaluate the efficacy of the glucagon-like peptide-1 receptor agonist liraglutide in Latino/Hispanic individuals with type 2 diabetes, in addition to comparing its treatment effects with those observed in non-Latino/Hispanic individuals. Analyses were performed on patient-level data from a subset of individuals self-defined as Latino/Hispanic from four phase III studies, the LEAD-3, LEAD-4, LEAD-6 and 1860-LIRA-DPP-4 trials. Endpoints included change in glycated haemoglobin (HbA1c) and body weight from baseline. In Latino/Hispanic patients (n = 505; 323 treated with liraglutide) after 26 weeks, mean HbA1c reductions were significantly greater with both liraglutide 1.2 and 1.8 mg versus comparator or placebo in the LEAD-3 and LEAD-4 studies, and with 1.8 mg liraglutide in the 1860-LIRA-DPP-4 trial. In LEAD-3 both doses led to significant differences in body weight change among Latino/Hispanic patients versus the comparator. With 1.8 mg liraglutide, difference in weight change was significant only in the 1860-LIRA-DPP-4 trial versus sitagliptin. For both endpoints Latino/Hispanic and non-Latino/Hispanic patients responded to liraglutide similarly. In summary, liraglutide is efficacious for treatment of type 2 diabetes in Latino/Hispanic patients, with a similar efficacy to that seen in non-Latino/Hispanic patients.
