PRIMARY outcome

Timeframe: Baseline, week 12

Population: Full Analysis Set includes all randomized patients with baseline and on-treatment value of HbA1c. Last observation carried forward (LOCF) was used as the imputation rule.

The change from baseline reflects the Week 12 HbA1c minus the Week 0 HbA1c. Means are adjusted for baseline HbA1c.

SECONDARY outcome

Timeframe: Baseline, week 12

Population: FAS patients with baseline HbA1c \> 7.0%. Non-completers were considered as failure imputation (NCF).

An absolute efficacy response is defined as HbA1c \<= 7.0% at 12 weeks. A non-response is defined as HbA1c \> 7.0% at 12 weeks.
