[Albiglutide (Eperzan): a new once-weekly agonist of glucagon-like peptide-1 receptors].

Albiglutide (Eperzan) is a new once-weekly agonist of Glucagon-Like Peptide-1 (GLP-1) receptors that is indicated in the treatment of type 2 diabetes. Two doses are available, 30 mg and 50 mg, to be injected subcutaneously once a week. It has been extensively evaluated in the HARMONY programme of eight large randomised controlled trials that were performed at different stages of type 2 diabetes, in comparison with placebo or an active comparator. The endocrine and metabolic effects of albiglutide are similar to those of other GLP-1 receptor agonists: stimulation of insulin secretion (incretin effect) and inhibition of glucagon secretion, both in a glucose-dependent manner, retardation of gastric emptying and increase of satiety. These effects lead to a reduction in glycated haemoglobin (HbA(1c)) levels, combined with a weight reduction. The overall tolerance profile is good. Albiglutide is currently reimbursed in Belgium after failure (HbA(1c) > 7.5%) of and in combination with a dual therapy with metformin and a sulfonylurea as well as in combination with a basal insulin (with or without oral antidiabetic drugs). To avoid hypoglycaemia, a reduction in the dose of sulfonylurea or insulin may be recommended. A once-weekly administration should increase patient's acceptance of injectable therapy and improve compliance.
