  Participant Flow

Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
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).

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
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.

  Show Outcome Measure 5


  Serious Adverse Events


  Other Adverse Events


  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
For participants who did not complete 8 and/or 24 weeks, respectively, last observation carried forward (LOCF) was used for analyses of secondary endpoints. All endpoints were evaluated by excluding data after rescue.
