Detailed Description:

TAK-875 is being developed at Takeda Global Research and Development, Inc. as an adjunct to diet and exercise to improve glycemic control in patients with T2DM.

Sitagliptin is an inhibitor of dipeptidyl peptidase-4 (DPP-4) approved as an adjunct to diet and exercise to improve glycemic control in adults with T2DM.

This study will investigate the effects of the combination of TAK-875 with a DDP-4 inhibitor on glycosylated hemoglobin reduction.
