  Purpose
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.

Condition Intervention Phase
Type 2 Diabetes Mellitus Insulin Resistance Drug: pioglitazone and glimepiride Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Multi Center, Open Label Study to Evaluate the Influence of Pioglitazone Treatment Over 6 Months on Metabolic Control in Type II Diabetic Patients Previously Treated With Insulin

Further study details as provided by IKFE Institute for Clinical Research and Development:

Primary Outcome Measures:
  • The proportion of patients with an increase in HbA1c by 0.5 % after 6 months of treatment compared to baseline HbA1c value [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Absolute change of HbA1c Insulin resistance according to minimal model and HOMA-S analysis change of insulin resistance according to minimal model and HOMA-S analysis to baseline first phase insulin response [ Time Frame: 6 months ]

Enrollment: 100
Study Start Date: April 2005
Study Completion Date: April 2007
Arms Assigned Interventions
Active Comparator: A
pioglitazone/glimepiride
Drug: pioglitazone and glimepiride
switch from any insulin treatment to 30 mg pioglitazone and 3 mg glimepiride.
Other Names:
  • Actos - pioglitazone
  • Amaryl - glimepiride

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).
