Abstract
Adding lixisenatide to basal insulin was effective for uncontrolled type 2 diabetes.
Glycemic control improved and body weight lowered during 24 weeks of treatment.
These benefits were achieved with a low risk of hypoglycemia in clinical practice.
These findings in the clinical practice setting support those of clinical trials.
Background
Basal insulin reduces fasting blood glucose levels, but postprandial blood glucose levels may remain higher. Traditional strategies with rapid insulin intensification can cause hypoglycemic episodes and weight gain. Glucagon-like peptide-1 receptor agonists, such as the short-acting lixisenatide, are able to control postprandial excursions, without weight gain, and with a low risk of hypoglycemic events.
Objective
Due to the limited data on the combination of lixisenatide with basal insulin (with or without oral antidiabetes drugs) in clinical practice, this study evaluated changes in parameters associated with glycemic control and anthropometric data after 24 weeks of this therapy intensification.
Methods
This was a multicenter, retrospective observational study of 129 patients with type 2 diabetes that was uncontrolled by basal insulin. Their treatment was intensified by the addition of lixisenatide at least 24 weeks before being included in the study. Data were retrospectively collected to determine changes in glycated hemoglobin (HbA1c) levels, blood glucose levels, weight, and body mass index. Adverse reactions and hypoglycemic events were also recorded.
Results
After 24 weeks of therapy intensification with lixisenatide, a significant reduction in HbA1c levels was observed (–1.1%; P < 0.001). An HbA1c <7% was achieved in 30.2% of patients, and 17.1% reached an HbA1c <6.5%. There was a reduction in fasting blood glucose (31.8 [60.3] mg/dL; P < 0.001) and postprandial blood glucose (55.0 [49] mg/dL; P < 0.001) levels, as well as body weight (4.0 [5.4] kg; P < 0.001) and body mass index (1.5 [1.9]; P < 0.001). The most commonly observed adverse reactions were nausea (n = 9), in line with previous studies. Hypoglycemia events were rare; only reported in 2 patients.
Conclusions
Intensification strategy based on lixisenatide added to basal insulin (with or without oral antidiabetes drugs) can be an effective treatment option in patients with uncontrolled type 2 diabetes. In this small, selected population, glycemic control was significantly improved in terms of HbA1, fasting blood glucose levels, and postprandial glucose levels, with a reduction of body weight and low risk of hypoglycemic events.
