Dulaglutide (LY-2189265) for the treatment of type 2 diabetes.

Dulaglutide is a new once-weekly glucagon-like peptide-1 receptor agonist for the management of hyperglycemia in adult patients with type 2 diabetes. It stimulates dose-dependent insulin secretion and reduces glucagon secretion, both in a glucose-dependent manner. Efficacy on blood glucose control and safety were demonstrated in the large AWARD program in type 2 diabetic patients treated with diet, metformin, dual oral therapy or insulin lispro with or without metformin, confirming findings of pilot studies in Caucasian patients and data in Japanese patients. Dulaglutide 1.5 mg once weekly was superior to metformin, sitagliptin, insulin glargine and exenatide twice daily, and non-inferior to liraglutide 1.8 mg once daily regarding the reduction in glycated hemoglobin. A modest but significant weight loss was consistently observed. Most frequent adverse events were transient and generally mild gastrointestinal disturbances. Clinical outcomes of dulaglutide will not be known until the large prospective cardiovascular outcome trial REWIND is complete.
