The blood samples were collected at Baseline, Week 4, Week 8 and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. The primary analysis was performed on the Intent-to-Treat (ITT) Population with Last observation carried forward (LOCF). Adjusted mean is presented as least square (LS) mean.
Fasted blood samples for HbA1c were collected at Baseline and Week 12. Participants were required to fast for at least 8 hours prior to laboratory samples and were told not to take the morning dose of study medication on these visit days and to refrain from eating until instructed to do so by study personnel in the clinic. When the participant had not fasted, the participant was rescheduled to return to the clinic to have a fasted sample taken. Baseline was Week 0. Change from Baseline was calculated by subtracting Baseline values from post-Baseline values. Only those participants with a value at Baseline and at Week 12 (after Last Observation Carried Forward \[LOCF\]) were used for this analysis. Adjusted mean is presented as least square mean.
