ATOS study: effectiveness and safety of insulin glargine 300 U/mL in the real world clinical practice in insulin-naïve type 2 diabetic patients in the Russian Federation

Abstract

Rationale: Basal insulin glargine 300 U/mL (Gla-300) is a second-generation basal insulin analogue that has comparable efficacy and lower variability compared to the first generation long-acting insulin analogue glargine 100 U/mL. Aim: To assess the effectiveness and safety of Gla-300 in insulin-nave type 2 diabetic patients in the real world practice in Russia. Materials and methods: ATOS (NCT03703869) was a 12-month, prospective observational international multicenter study. The study included 4422 adults ( 18 years) with uncontrolled type 2 diabetes (HbA1c 7 and 11%) with 1 oral anti-hyperglycemic drug and for whom the treating physician had decided to add Gla-300. We performed a post-hoc sub-analysis of the study participants recruited in Russia. Results: The Russian study group included 1493 patients receiving Gla-300. At 6 months, 25.9% of the patients achieved their predefined individualized HbA1c target and 53.3% achieved their HbA1c target at month 12. Their mean ( SD) HbA1c level decreased from 9.3 0.9% at baseline to 7.6 0.7% and 7.2 0.7 at months 6 and 12. The incidence of hypoglycemia was generally low; overall, severe hypoglycemia was reported only in 0.07% and 0.13% of the patients at 6 and 12 months. The baseline average daily dose of Gla-300 was 13.2 4.9 Units; it to 23.6 9.1 and 26.0 9.8 Units at months 6 and 12. Conclusion: In the real world setting, initiation of insulin Gla-300 in type 2 diabetic patients who had been out of their target glucose range with oral hypoglycemic agents is associated with improved glycemic control and low risk of hypoglycemia.
