Expert Opinion on Optimising Type 2 Diabetes Treatment Using Fixed-Ratio Combination of Basal Insulin and GLP-1 RA for Treatment Intensification and Simplification

The management of type 2 diabetes (T2D) often necessitates treatment intensification, and sometimes simplification to achieve glycaemic targets and mitigate complications. This expert opinion paper evaluates the use and positioning of the fixed-ratio combinations (FRCs) of basal insulin (BI) and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) in optimising T2D management. On the basis of the evidence presented and discussions, these FRCs offer a promising approach for both treatment intensification and simplification in people with suboptimal glucose control despite receiving various therapies. In treatment intensification, FRCs provide a synergistic effect by addressing multiple pathophysiological defects contributing to hyperglycaemia. These FRCs effectively control both fasting and postprandial glucose (PPG) excursions, offering significantly improved glycaemic control with a lower hypoglycaemia risk and weight neutrality compared to traditional or complex insulin regimens. Moreover, the reduced injection frequency (once daily) and flexibility in the dosing schedule (with any major meal of the day) help mitigate patient resistance to insulin initiation or titration. This further reduces treatment burden, facilitating treatment adherence and enhancing patient convenience. These key benefits of FRCs over complex insulin regimens play a crucial role in long-term glycaemic management and overall treatment outcomes. Hence, the timely use of FRCs in the treatment algorithm for people with T2D represents a valuable strategy for optimising glycaemic control, addressing treatment barriers and enhancing patient-reported outcomes.
