Clinical Article
Seino Y et al. – 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.
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 20 μg 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 achieveHbA1c <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.
