Aim: Sulphonylureas (SUs) are often used as first‐line treatments for type 2 diabetes in Japan, hence it is important to study new antidiabetic drugs in combination with SUs in Japanese patients. Methods: The efficacy and safety of the once‐daily human glucagon‐like peptide‐1 (GLP‐1) analogue liraglutide were compared in 264 Japanese subjects [mean body mass index (BMI) 24.9 kg/m 2 ; mean glycated haemoglobin (HBA1c) 8.4%] randomized and exposed to receive liraglutide 0.6 mg/day (n = 88), 0.9 mg/day (n = 88) or placebo (n = 88) each added to SU monotherapy (glibenclamide, glicazide or glimeprimide) in a 24‐week, double‐blind, parallel‐group trial. Results: The mean change in HBA1c from baseline to week 24 (LOCF) was −1.56 (s.d. 0.84) and −1.46 (s.d. 0.95) with liraglutide 0.9 and 0.6 mg respectively, and −0.40 (s.d. 0.93) with placebo. HBA1c decreased in the placebo group from 8.45 to 8.06%, while liraglutide reduced HBA1c from 8.60 to 7.14%, and from 8.23 to 6.67% at the 0.6 and 0.9 mg doses respectively. Mean HBA1c at week 24 of the two liraglutide groups were significantly lower than the placebo group (p < 0.0001 for both). More subjects reached HBA1c < 7.0% with liraglutide (0.6 mg: 46.5%; 0.9 mg: 71.3%) vs. placebo (14.8%). Fasting plasma glucose (FPG) levels were significantly improved with liraglutide (difference −1.47 mmol/l and −1.80 mmol/l with 0.6 and 0.9 mg vs. placebo; p < 0.0001). Overall safety was similar between treatments: no major hypoglycaemic episodes were reported, while 84/77/38 minor hypoglycaemic episodes occurred in the 0.6 mg/0.9 mg and placebo treatment groups (all in combination with SU), reflecting lower ambient glucose levels. No relevant change in mean body weight occurred in subjects receiving liraglutide (0.6 mg: 0.06 kg; 0.9 mg: −0.37 kg), while mean body weight decreased in subjects receiving placebo (−1.12 kg). Conclusions: The addition of liraglutide to SU treatment for 24 weeks dose‐dependently improved glycaemic control vs. SU monotherapy, without causing major hypoglycaemia or weight gain or loss.
