INTRODUCTION:: The safety and efficacy of liraglutide in combination with an oral antidiabetic drug (OAD) compared with combination of two OADs were assessed in Japanese patients with type 2 diabetes. MATERIALS AND METHODS:: This was a 52-week, open-label, parallel-group trial in which patients whose type 2 diabetes was inadequately controlled with a single OAD (glinide, metformin, α-glucosidase inhibitor or thiazolidinedione) were randomized 2:1 to either pretrial OAD in combination with liraglutide 0.9 mg/day (liraglutide group; n = 240) or pretrial OAD in combination with an additional OAD (additional OAD group; n = 120). The primary outcome measure was the incidence of adverse events (AEs). RESULTS:: Overall, 86.3% of patients in the liraglutide group and 85.0% of patients in the additional OAD group experienced AEs; these were similar in nature and severity. Adverse event rates were 361 and 331 per 100 patient-years of exposure, respectively. Confirmed hypoglycemia was rare (seven episodes in two patients on liraglutide, and two in two patients on additional OAD). There were no reported pancreatitis events, and no unexpected safety signals were identified. Mean reductions in glycosylated hemoglobin were significantly greater in the liraglutide group than the additional OAD group [estimated mean treatment difference −0.27% (95% confidence interval (CI) −0.44, −0.09; P = 0.0026)]; reductions in mean fasting plasma glucose levels were also greater with liraglutide [estimated mean difference −5.47 mg/dL (−0.30 mmol/L; 95% CI: −10.83, −0.10; P = 0.0458)]. CONCLUSIONS:: Liraglutide was well tolerated and effective as combination therapy with an OAD in Japanese patients with type 2 diabetes.Reductions in HbA1c were significantly greater with liraglutide and an OAD than with two OADs in combination. Overall, the data suggest that liraglutide plus an OAD may be more effective than a combination of two OADs in Japanese subjects with type 2 diabetes with a safety profile consistent with previous findings.
