PRIMARY outcome

Timeframe: Baseline to end of Period II (up to 4.5 years)

Population: ITT Efficacy Population: Enrolled patients with a baseline and at least one post-baseline measurement of HbA1c in Study Period II (including only Study Period II); patients analyzed according to treatment as randomized.

Treatment failure is defined as one of the following:1. HbA1c exceeding 9% at any visit after the initial 3 months of treatment (i.e., earliest at Month 6), on the maximally tolerated dose of antidiabetic agents. 2. HbA1c exceeding 7% at 2 consecutive visits 3 months apart, after the initial 6 months of treatment (i.e., earliest at Month 9), on the maximally tolerated dose of antidiabetic agents.

Timeframe: Year 3 in Period II

Population: ITT Efficacy Population. The analysis included only time points up to that week where at least 25% of the originally enrolled population was still in the study. Missing data at Year 3 was not imputed.

HOMA-B at Year 3. HOMA-B is an index of beta-cell function and was calculated as: HOMA-B = (20 x fasting insulin (measured in pmol/L))/((fasting glucose (measured in mmol/L) - 3.5) x 7.175).
