Efficacy and safety of a morning injection of insulin glargine 300 units/mL versus insulin glargine 100 units/mL in adult patients with type 1 diabetes: A multicentre, randomized controlled trial using continuous glucose monitoring.

Time in range and glycaemic variability were similar for Gla-300 and Gla-100 recipients at the end of study in the mITT population of relatively well-controlled patients with T1D. In patients with end-of-study HbA1c <7.5%, exploratory analyses suggested that Gla-300 provided improvements in time in range compared with Gla-100.
