Patients were randomised to receive trelagliptin (100 mg) once per week, alogliptin (25 mg) once per day, or placebo for 24 weeks. The primary outcome was between-groups difference in change in HbA1c concentration from baseline to the end of treatment at 24 weeks. The non-inferiority margin was 0.4%.
The least squares mean change in HbA1c concentration was reported as −0.33% in the trelagliptin group (SE 0.059) and −0.45% in the alogliptin group (0.061). The least squares mean difference (trelagliptin minus alogliptin) of change from baseline in HbA1c concentration was 0.11% (95% CI −0.054 to 0.281). Trelagliptin was non-inferior to alogliptin. No hypoglycaemia was reported with trelagliptin and the drug was well tolerated.
