Advances in the treatment of type 2 diabetes: impact of dulaglutide

Abstract

The purpose of this review is to provide a review of current data of the most recently approved glucagon-like peptide (GLP)-1-receptor agonist, dulaglutide, in the treatment of type 2 diabetes. To complete this, a PubMed search was performed to identify manuscripts published from 1947 to July 2015. The search terms “Trulicity”, “dulaglutide”, and “LY2189265” were utilized, and publications were included if they evaluated the pharmacology, pharmacokinetics, efficacy, safety, or patient-reported outcomes of dulaglutide. Dulaglutide is a GLP-1 receptor agonist that mimics endogenous GLP-1, the hormone produced in response to food intake. Modifications have been made to the molecule to delay breakdown and allow for once-weekly dosing. Dulaglutide has been studied as monotherapy and in combination with several agents, including metformin, glimepiride, pioglitazone, and insulin lispro. Dulaglutide has demonstrated superior efficacy compared to placebo, metformin, insulin glargine, sitagliptin, and twice-daily exenatide. It was found to be noninferior to liraglutide. The most common adverse effects in clinical studies were gastrointestinal-related adverse events, and patient satisfaction was high with the use of dulaglutide. Dulaglutide is an appealing option for the treatment of type 2 diabetes, based on its once-weekly dosing, A1c lowering comparable to liraglutide, weight reduction comparable to exenatide, and a similar adverse-effect profile to other GLP-1 receptor agonists.
