Aims To assess the efficacy and safety of alogliptin added to insulin in patients with type 2 diabetes inadequately controlled with insulin alone or combined with metformin. Methods In this 26-week, double-blind, placebo-controlled study, 390 patients were randomized to receive alogliptin 12.5 mg (n = 131), alogliptin 25 mg (n = 129) or placebo (n = 130) once daily, as add-on to stable insulin therapy with or without metformin. The primary endpoint was change in haemoglobin A(1C) (HbA(1C)) at week 26. Results At week 26, mean HbA(1C) changes from the mean baseline value of 9.3% were significantly greater for alogliptin 12.5 mg (-0.63 +/- 0.08%) and alogliptin 25 mg (-0.71 +/- 0.08%) than placebo (-0.13 +/- 0.08%; p < 0.001). Significantly greater proportions of patients receiving alogliptin 12.5 or 25 mg than placebo had HbA(1C) decreases of >= 0.5, >= 1.0 and >= 1.5%. Insulin doses remained unchanged, and there were no differences in the proportions of patients experiencing hypoglycaemia among placebo (24%), alogliptin 12.5 mg (27%) and alogliptin 25 mg (27%). Mean weight increases from baseline at week 26 were similar for placebo (0.6 +/- 0.2 kg), alogliptin 12.5 mg (0.7 +/- 0.2 kg) and alogliptin 25 mg (0.6 +/- 0.2 kg). Incidences of overall adverse events, and of gastrointestinal, dermatological and infection-related events, were similar among groups. Conclusions Adding alogliptin to previous insulin therapy (with or without metformin) significantly improved glycaemic control in patients with type 2 diabetes inadequately controlled on insulin, without causing weight gain or increasing the incidence of hypoglycaemia. Further studies are warranted to explore the role of alogliptin added to optimized basal insulin regimens.
