This study has been completed.

Information provided by:
GlaxoSmithKline
ClinicalTrials.gov Identifier:
NCT00318656
First received: April 25, 2006
Last updated: April 10, 2009
Last verified: April 2009
  Purpose

A better glycemic control is associated with less complications (cardiac diseases, blindness, etcetera) for type 2 diabetic patients. The objective is to study if rosiglitazone may lead to a more regular glycemic pattern with less hyperglycemia and hypoglycemia episodes than with a sulphonylurea (glimepiride).


Condition Intervention Phase
Non-Insulin-Dependent Diabetes Mellitus
Drug: rosiglitazone-metformin fixed dose combination
Drug: metformin + glimepiride
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Comparison of the Effects of Rosiglitazone and Glimepiride, Both Given in Combination With Metformin, on 24-Hour Glycemia in Type 2 Diabetes Patients Not Controlled With Metformin Alone. A 3-Month Multicentre, Randomized, Parallel-Group, Open-Label Study.
