Participant Flow

First participant enrolled: 24 Oct 2011. Last participant completed 24 week period: 07 Jan 2013. 311 participants were enrolled, 219 were randomized in 45 centers in 5 European countries and in North America. Men and women aged \>= 18 years with inadequate glycemic control (HbA1c 7.0% to 10.5% prior to randomization).

During enrollment, diet and life-style advice was given to participants and was reinforced during a placebo lead-in period. Dose of anti-hyperglycemic combination therapy of metformin \>= 1500 mg/day and maximum tolerated dose which must be at least half the maximum dose of sulfonylurea for at least 8 weeks prior to enrollment were to remain stable.
