Effectiveness and safety of insulin glargine 300 U/mL in insulin‐naïve patients with type 2 diabetes after failure of oral therapy in a real‐world setting

AIM: To evaluate the effectiveness and safety of initiating basal insulin‐supported oral therapy (BOT) with insulin glargine 300 U/mL (Gla‐300) in patients with type 2 diabetes inadequately controlled on oral antidiabetic drugs (OADs). MATERIALS AND METHODS: This non‐interventional, multi‐centre, prospective 52‐week study, conducted in Germany and Switzerland, documented patients with type 2 diabetes with an HbA1c of between 7.5% and 10.0%, currently treated with OADs, after the physician had decided to start a BOT regimen with Gla‐300. The primary endpoint was the rate of achievement of the individualized predefined HbA1c target. RESULTS: Of 1748 patients included, 1153 comprised the full analysis set, of whom 721 completed documentation of 12 months of Gla‐300 treatment. Twelve months after starting Gla‐300, 49.9% achieved their individualized HbA1c target, and 61.1% achieved either their HbA1c target or a fasting plasma glucose (FPG) of ≤110 mg/dL. Mean HbA1c decreased by −1.22% ± 1.05% to 7.28% ± 0.92% and mean FPG by −51.5 (±48.63) mg/dl to 132.9 ± 33.0 mg/dL. Median duration of HbA1c target achievement was 341 days and probability to remain on target after 6 months was 81%. Hypoglycaemia incidence and rates remained low after 12 months of Gla‐300 treatment; no severe or severe nocturnal hypoglycaemia was observed. Body weight remained unchanged. CONCLUSIONS: Starting a BOT regimen with Gla‐300 allowed about 60% of 721 German and Swiss patients with inadequately controlled type 2 diabetes to achieve glycaemic control within 12 months in daily clinical practice. Glycaemic control was achieved without weight gain or increased risk of nocturnal or severe hypoglycaemia.
