A study by Vilsboll et al in patients receiving stable-dose insulin therapy (with or without concomitant metformin) found that the addition of sitagliptin produced a greater reduction in FPG (by 15 mg/dL [0.8 mmol/L]) and 2-hour postprandial glucose (by 36.1 mg/dL [2 mmol/L]) than did placebo. Sitagliptin reduced HbA1c by 0.6%, while no reduction was seen with placebo. In addition, 13% of patients attained an HbA1c level of less than 7% with sitagliptin, compared with 5% with placebo.
