Placebo‐controlled, randomized trial of the addition of once‐weekly glucagon‐like peptide‐1 receptor agonist dulaglutide to titrated daily insulin glargine in patients with type 2 diabetes (AWARD‐9)

Aim To compare the addition of weekly dulaglutide vs the addition of placebo to titrated glargine in patients with type 2 diabetes (T2D) with sub‐optimum glycated haemoglobin (HbA1c) concentration. Materials and Methods Patients (N = 300) from this phase III, double‐blind, parallel‐arm, placebo‐controlled study were randomized to weekly subcutaneous injections of dulaglutide 1.5 mg or placebo with titrated daily glargine (mean ± standard deviation baseline dose: 39 ± 22 U), with or without metformin (≥1500 mg/d). The primary endpoint was superiority of dulaglutide/glargine to placebo/glargine with regard to change from baseline in HbA1c level at 28 weeks. Results Least squares (LS) mean ± standard error (s.e.) HbA1c changes from baseline were −1.44 ± 0.09% (−15.74 ± 0.98 mmol/mol) with dulaglutide/glargine and −0.67 ± 0.09% (−7.32 ± 0.98 mmol/mol) with placebo/glargine at 28 weeks (LS mean difference [95% confidence interval] −0.77% [−0.97, −0.56]; P
