Abstract

Introduction

This multicenter, randomized study assessed the efficacy and safety of the dipeptidyl peptidase 4 inhibitor sitagliptin added to insulin monotherapy in Japanese patients with type 2 diabetes mellitus (T2DM).

Materials and methods

This study had an initial 16-week, double-blind treatment period in which 266 patients on diet/exercise and insulin monotherapy for ≥12 weeks were randomized (1:1) to sitagliptin 50 mg q.d. (N = 129; mean baseline HbA1c = 8.9 %) or placebo (N = 137; mean baseline HbA1c = 8.9 %). It was followed by a 36-week, open-label treatment period in which all patients received sitagliptin 50 mg q.d., which could have been increased to 100 mg q.d. for patients meeting predefined glycemic criteria.

Results

After 16 weeks, treatment with sitagliptin resulted in significant placebo-adjusted mean decreases from baseline in HbA1c, fasting plasma glucose, and 2-h postmeal glucose of −0.9 % (p < 0.001), −11.4 mg/dl (p = 0.007), and −39.9 mg/dl (p < 0.001), respectively. During the double-blind period, adverse experiences (AEs) were reported with similar frequency in both treatment groups and the incidence of gastrointestinal AEs was low. The incidence of hypoglycemia AEs in the sitagliptin group (20.2 %) was higher than in the placebo group (12.4 %), but the between-group difference was not statistically significant (p = 0.097). Small increases from baseline in body weight were observed with sitagliptin [sitagliptin: 0.6 kg (p < 0.001), placebo: 0.1 kg (p = 0.498)]. In the open-label period, sustained improvements in glycemic parameters were observed with sitagliptin treatment, and sitagliptin was generally well tolerated.

Conclusions

In Japanese patients with T2DM inadequately controlled on insulin monotherapy, the addition of sitagliptin provided significant improvements in glycemic parameters and was generally well tolerated.
