Insulin Resistance, Type 2 Diabetes Mellitus
Conditions
Keywords
type 2 diabetes, insulin treatment, ß-cell function
Brief summary
The goal of the study is to demonstrate whether a switch from insulin therapy to an oral therapy with pioglitazone/glimepiride will lead to a deterioration of glycemic control (increase in HbA1c by more than 0.5 %) within a 6 month observation period.
Detailed description
To demonstrate that reconverting type 2 diabetic patients from insulin treatment to oral treatment using pioglitazone in combination with or without glimepiride is possible without deterioration of blood glucose control. Primary aim is to maintain glycaemic control (HbA1c) defined as an increase in HbA1c of not more than 0.5 % after 6 months of treatment (visit 7) compared to baseline HbA1c value (screening visit V1).
Interventions
switch from any insulin treatment to 30 mg pioglitazone and 3 mg glimepiride.
