Abstract

Abstract: Exogenous insulin has been the mainstay treatment for individuals living with type 1 diabetes (T1D). Although there has been tremendous growth in both pharmacological and technological advancements, insulin monotherapy has proven to be insufficient for maintaining optimal glycaemic targets for most adults with T1D. At present, there is still no breakthrough for the treatment of T1D. Adjunctive pharmacotherapies might therefore complement insulin management to achieve better glycaemic control, while possibly offering additional benefits. Recent interest in re‐purposing glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs), a leading antihyperglycaemic medication class approved for type 2 diabetes, has prompted the field to seek extended potential for the T1D population. The adjunctive use of GLP‐1RAs has been at the forefront of T1D research, albeit with some conflicting trial findings to date. However, the potential of GLP‐1 agonism for T1D may have been underestimated, possibly from missed opportunities or categorized effects. Moreover, some GLP‐1RAs have demonstrated extra‐pancreatic potential with emerging multi‐organ protection involving the heart, kidneys, liver and brain in varied cohorts, which may bode well for the growing T1D profile of comorbid complications. This narrative review aims to summarize and critically appraise the current evidence‐based literature from large‐scale randomized controlled trials and closed‐loop system pilot studies that examined GLP‐1RAs as adjunctive therapy for T1D. Furthermore, we outline uncharted opportunities with GLP‐1 agonism using versatile approaches in selected T1D populations that may inspire and re‐direct future research in this field.
