In the randomized controlled EDITION trials, Gla-300 demonstrated comparable glycemic control to insulin glargine 100 U/mL, but with less hypoglycemia. This study examined the performance of Gla-300 in real-world clinical settings. The aim was to evaluate clinical outcomes of patients with type 2 diabetes (T2D) using basal insulin who switched to either Gla-300 or other basal insulins in real-world clinical practice. The DELIVER 2 retrospective observational study used data from the Predictive Health Intelligence Environment database of real-world electronic medical records (representing 26 integrated health delivery networks). Included patients were adults with T2D using basal insulin, with data for 12 months prior to (baseline) and up to 6 months after (follow-up) switching to either Gla-300 or other basal insulins (index date: March 1, 2015 through February 29, 2016). All patients had glycated hemoglobin (A1C) levels measured < 6 months prior to index date and > 90 days after. The endpoints were A1C change, incidence and rate of hypoglycemia, and patient proportions reaching target A1C < 7.0% and < 8.0%. Following a 1:1 ratio propensity score matching, 947 patients who switched to Gla-300 and 947 patients who switched to other basal insulins were identified. Mean baseline A1C levels were 8.89% and 8.92%, which significantly decreased to 8.42% and 8.50% (P < 0.001 for both) 6 months after switching to Gla-300 or other basal insulins, respectively. A1C reductions were comparable in both cohorts (−0.48% for Gla-300 vs −0.41% for other basal insulins; P=0.44). Significantly fewer patients who switched to Gla-300 experienced hypoglycemia vs those who switched to other basal insulins at 6-month follow-up (incidence: 15.1% vs 19.9%, respectively; P=0.03). Adjusted for baseline hypoglycemia, switching to Gla-300 compared to other basal insulins was associated with a significantly lower hypoglycemia event rate at 6 months (difference between least squares means: 2.67 events/100 patient-months, P=0.001), and significantly lower incidence and event rates of hypoglycemia requiring hospitalization or emergency care. Significantly lower hypoglycemia was also seen at 3 months of follow-up in the Gla-300 switchers. At 6 months of follow-up, patients on Gla-300 and those on other basal insulins were equally likely to reach A1C < 7.0% (16.9% vs 18.7%, respectively; P=0.35) and A1C < 8.0% (45.0% vs 42.0%, respectively; P=0.31). In real-world clinical settings, switching to Gla-300 is associated with a significantly lower risk of hypoglycemia than switching to other basal insulins, while delivering comparable glycemic control.
