Basal insulin peglispro versus insulin glargine in insulin‐naïve type 2 diabetes: <scp>IMAGINE</scp> 2 randomized trial

Aims To compare, in a double‐blind, randomized, multi‐national study, 52‐ or 78‐week treatment with basal insulin peglispro or insulin glargine, added to pre‐study oral antihyperglycaemic medications, in insulin‐na&#239;ve adults with type 2 diabetes. Material and methods The primary outcome was non‐inferiority of peglispro to glargine with regard to glycated haemoglobin (HbA1c) reduction (margin = 0.4%). Six gated secondary objectives with statistical multiplicity adjustments focused on other measures of glycaemic control and safety. Liver fat content was measured using MRI, in a subset of patients. Results Peglispro was non‐inferior to glargine in HbA1c reduction [least‐squares (LS) mean difference: −0.29%, 95% confidence interval (CI) −0.40, −0.19], and had a lower nocturnal hypoglycaemia rate [relative rate 0.74 (95% CI 0.60, 0.91); p = .005), more patients achieving HbA1c
