Participant Flow

Participants were enrolled at a total of 113 study sites in the United States, South Africa, Europe, and Russia. The first participant was screened on 15 November 2011. The last participant observation occurred on 21 October 2013.

605 participants entered the qualifying period; 465 were randomized, and 464 were randomized and treated (Safety Analysis Set). Of these, 8 were excluded due to major eligibility criteria protocol violation or had baseline but no on-treatment data; thus, 456 were included in the Full Analysis Set.

PRIMARY outcome

Timeframe: Baseline; Week 24

Population: Participants in the Full Analysis Set (randomized participants who received ≥ 1 dose of study treatment with a baseline and at least one postbaseline measurement of HbA1c, excluding subjects with major eligibility violations and analyzed based on the randomized treatment regardless of actual treatment received) with available data were analyzed.

The average (mean) change from baseline in HbA1c at Week 24 was analyzed.
