Liraglutide-bolus vs Glargine-bolus Therapy in Overweight/Obese Type 2 Diabetes Patients (LiraGooD)

An increasing number of patients with type 2 diabetes are treated with insulin. Patients with diabetes receiving intensive insulin therapy with various combinations of basal and prandial insulin can be caught in a vicious but common cycle, whereby insulin requirements increase over time, and this in turn contributes to weight gain and hypoglycemia and further increases in insulin dosing. At this stage, clinicians observe a practical limit to the efficacy of insulin titration alone on glucose-lowering and often add or continue metformin to reduce insulin resistance. Injectable glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as liraglutide, are a relatively new addition to our treatment armamentarium. These drugs improve glucose control and insulin sensitivity and contribute to weight loss. Treatment with basal insulin plus GLP-1RAs is well-established in diabetes guidelines and may be as effective as adding prandial insulin therapy. When GLP-1 RAs are started, a preemptive reduction in insulin dosage by 25% to 30% in patients with HbA1c \< 9% may reduce the risk for hypoglycemia. In overweight/obese patients with uncontrolled type 2 diabetes treated with more than three oral antidiabetic drugs (OADs) or high doses of premix insulin, Is basal-prandial insulin therapy the option treatment algorithm? Such an intensification strategy carries risk of increased hypoglycaemia and weight gain, both of which are associated with worse long-term outcomes. There have no randomized, controlled trials to evaluate the efficacy and safety of GLP-1 RAs vs insulin glargine added to prandial insulin in overweight/obese patients with uncontrolled type 2 diabetes. So, the current 24-week, prospective, open-label, randomized, multicenter, parallel group trial will be preformed to assess whether Liraglutide plus prandial insulin therapy was superior to glargine plus prandial insulin therapy in overweight/obese patients with uncontrolled type 2 diabetes.
