Participant Flow

Phase II. First patient in: 31 July 2005. Last patient, last visit: 13 February 2006. The study was conducted at 8 centers in Japan.

Patients 20-69 years of age with type 2 diabetes mellitus and inadequate glycemic control (HbA1c ≥6.5% and \<10% at Week -2) were eligible for randomization following at least 8 weeks of diet/exercise and antihyperglycemic agent (AHA) wash-off (for patients previously on an AHA), including a 2-week placebo run-in.

PRIMARY outcome

Timeframe: Baseline and Week 4

Population: The Per Protocol population included patients with baseline and Week 4 (i.e., final primary timepoint) values for this outcome and excluded patients who met predefined criteria for protocol violations.

Change from baseline at Week 4 is defined as 24-hour weighted mean glucose (24hr-WMG) at Week 4 minus 24hr-WMG at Week 0.
