This study will examine whether biomarkers of B-cell function measured early in the study (1, 3, and/or 6 months) will predict long-term changes in B-cell function (as represented by HOMA-B).

Beta Cell Function Tests Over Time In Patients With T2dm Randomized To Metformin Or Rosiglitazone
Analyzing Beta Cell Function Tests Over Time In Patients With Type 2 Diabetes Mellitus Randomized To Metformin Or Rosiglitazone
The purpose of this study is to determine whether markers of b-cell function can predict changes in B-cell function over time in patients with type 2 diabetes mellitus (T2DM) randomized to treatment with metformin or rosiglitazone.
The study terminated on 17-Jul-07 due to concerns about long-term cardiovascular safety of Avandia and slow patient enrollment. There were no specific safety issues raised within the trial.
