Glargine Followed by Metformin
Basal insulin glargine for 3 months titrated to achieve a morning fasting blood glucose of 80-90 mg/dl, followed by open-label metformin (titrated up to 2000 mg/day) for 9 months. Metformin: Titrated to 1000 mg BID Glargine: Titrated to target fasting glucose \<90 mg/dl
Placebo
Placebo - masked to metformin-alone. Placebo will be titrated to the maximum number of tablets equivalent to maximum dose of metformin. Placebo: Matching to metformin 1000 mg BI
