Treating Type 2 Diabetes With Early, Intensive, Multimodal Pharmacotherapy: Real‐World Evidence From an International Collaborative Database

Abstract

Aims: We compared the glycaemic and cardiorenal effects of combination therapy involving metformin, pioglitazone, sodium-glucose-linked-cotransporter-2 inhibitor (SGLT2i), and glucagon-like peptide-1 receptor agonist (GLP-1RA) versus a more conventional glucocentric treatment approach combining sulphonylureas (SU) and insulin from the point of type 2 diabetes (T2D) diagnosis.Methods: We performed a retrospective cohort study using the Global Collaborative Network in TriNetX. We included individuals prescribed metformin, pioglitazone, an SGLT2i, and a GLP-1 RA for at least 1-year duration, within 3 years of a T2D diagnosis, and compared with individuals prescribed insulin and a SU within the same temporal pattern. Individuals were followed up for 3 years.Results: We propensity score-matched (PSM) for 26 variables. A total of 1762 individuals were included in the final analysis (n=881 per cohort). At 3-years, compared to the insulin/SU group, the metformin/pioglitazone/SGLT2i/GLP-1 RA group had a lower risk of heart failure (HR 0.34, 95% CI 0.13–0.87, p=0.018), acute coronary syndrome (HR 0.29, 95% CI 0.12–0.67, p=0.002), stroke (HR 0.17, 95% CI 0.06–0.49, p<0.001), chronic kidney disease (HR 0.50, 95% CI 0.25–0.99, p=0.042), and hospitalisation (HR 0.59, 95% CI 0.46–0.77, p<0.001).Conclusions: In this real-world study, early, intensive polytherapy, targeting the distinct pathophysiological defects in T2D, is associated with significantly more favourable cardiorenal outcomes, compared to insulin and SU therapy.
