OBJECTIVE: To assess the efficacy and safety of teneligliptin as add-on to insulin monotherapy in patients with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS: In a 16-week, double-blind period, 148 Japanese T2DM patients with inadequate glycemic control with insulin and diet/exercise therapies were randomized to placebo or teneligliptin 20 mg. In a subsequent 36-week, open-label period, all patients received teneligliptin once daily. The primary outcome measure was change in HbA1c at the end of the double-blind period. RESULTS: The difference between placebo and teneligliptin in change in HbA1c in the double-blind period (least squares mean +/- SE) was -0.80% +/- 0.11%; teneligliptin was superior (ANCOVA, P < 0.001). The HbA1c-lowering effect of teneligliptin was maintained throughout the open-label period. The incidence of adverse events was 53.5% with placebo and 44.2% with teneligliptin in the double-blind period, 66.7% in the placebo/teneligliptin group in the open-label period, and 77.9% in the teneligliptin/teneligliptin group over both double-blind/open-label periods. The incidence of hypoglycemic symptoms was 11.1% in the placebo/teneligliptin group in the open-label period and 27.3% in the teneligliptin/teneligliptin group over both double-blind/open-label periods. CONCLUSION: Teneligliptin was effective and well tolerated in Japanese T2DM patients with inadequate glycemic control. CLINICAL TRIAL REGISTRATION: NCT02081599.
