NCT01490918

Brief Summary

Primary objective To evaluate the efficacy of Acarbose add-on therapy on glucose control in subjects with type 2 diabetes inadequately controlled with Metformin and Sitagliptin combination therapy. The effect of acarbose, an alpha glucosidase inhibitor as a third-line therapeutic medication in subject who are inadequately controlled with metformin and DPP4 inhibitor will be evaluated with multicenter, randomized, 24-week, double blinded, placebo-controlled study in Korea.
