Participant Flow

First participant enrolled: 06-Jun-2014; Last participant last visit of ST period: 02-Feb-2015; 266 participants were enrolled in 20 Japanese centers. 183 Japanese men or women aged \>=20 years with inadequate glycemic control (HbA1c levels of \>=7.2% to \<11.0%) with diet, exercise and on stable dose of insulin +/- DPP-4 inhibitor were treated.

A 8-week wash-out period was applicable only for participants on ongoing anti-diabetic treatment at enrollment. A 2-week lead-in period was applicable for all participants.
