Abstract
Aims: To assess the efficacy and safety of once-daily lixisenatide versus placebo in Asian patients with type 2 diabetes insufficiently controlled on basal insulin±sulfonylurea. Methods: In this 24-week, randomized, double-blind, placebo-controlled, parallel-group, multicentre study, participants (mean baseline HbA1c 8.53%) from Japan, Republic of Korea, Taiwan and the Philippines received lixisenatide (n=154) or placebo (n=157) in a stepwise dose increase to 20μg once daily. The primary endpoint was HbA1c change from baseline to week 24. Results: Once-daily lixisenatide significantly improved HbA1c versus placebo (LS mean difference vs. placebo=-0.88% [95%CI=-1.116, -0.650]; p<0.0001), and allowed more patients to achieve HbA1c <7.0% (35.6 vs. 5.2%) and ≤6.5% (17.8 vs. 1.3%). Lixisenatide also significantly improved 2-h postprandial plasma glucose and glucose excursion, average 7-point self-monitored blood glucose and fasting plasma glucose. Lixisenatide was well tolerated; 86% of patients on lixisenatide completed the study versus 92% on placebo. Ten (6.5%) lixisenatide and 9 (5.7%) placebo patients experienced serious adverse events. More lixisenatide patients [14 (9.1%)] discontinued for adverse events versus placebo [5 (3.2%)], mainly with gastrointestinal causes. Nausea and vomiting were reported in 39.6 and 18.2% of patients on lixisenatide versus 4.5 and 1.9% on placebo. Symptomatic hypoglycaemia was more frequent with lixisenatide (42.9%) versus placebo (23.6%), but was similar between groups (32.6 vs. 28.3%, respectively), in those not receiving sulfonylureas. No severe hypoglycaemia was reported. Conclusions: In an Asian type 2 diabetes population insufficiently controlled by basal insulin±sulfonylurea, once-daily lixisenatide significantly improved glycaemic control, with a pronounced postprandial effect, and was well tolerated.
