Efficacy of Pioglitazone and Glimepiride Combination Therapy in Treating Subjects With Type 2 Diabetes Mellitus.

Summary

The purpose of this study is to determine the effect of pioglitazone, once daily (QD), and glimepiride combination therapy compared to glimepiride monotherapy in subjects with Type 2 Diabetes.

Description

Tight glycemic control is mandatory for the prevention and treatment of vascular complications in patients suffering from diabetes mellitus. After onset of Type 2 Diabetes, patients are usually treated with diet along with or without different combinations of oral drugs. One first-line drug class are sulfonylurea drugs that are preferably provided to patients who are not obese. The mode of action of sulfonylurea drugs is to increase beta-cell secretion, but it could be shown that they lead to deterioration of the beta-cell secretion product over time, resulting in increased proinsulin secretion. Since proinsulin is an independent cardiovascular risk factor, recent publications have demonstrated an increased risk for cardiovascular events in patients treated with sulfonylurea drugs as compared to other treatment methods.

Combination therapy of sulfonylurea drugs with glitazones has been shown to counterbalance the effect of deteriorated beta-cell secretion and to improve insulin sensitivity and the levels of proinsulin, C-peptide and other laboratory surrogate markers for cardiovascular risk. Proving that the treatment of diabetic patients with higher doses of beta cytotropic agents can be avoided and beta-cell function can be preserved by using pioglitazone in combination with low dose sulfonylurea drugs, it will be possible to optimize the treatment of patients with type 2 diabetes who are not controlled efficiently by sulfonylurea drugs monotherapy.

In this study patients will be enrolled who are inefficiently treated with a Glimepiride monotherapy. Patients will be either randomized to a combinational therapy of Pioglitazone and Glimepiride or Glimepiride monotherapy. If possible, study medication will be up-titrated to maximal dosage levels in both treatment arms to observe maximal and comparable treatment effects. Stable effects on beta-cell function will be observed after 24 weeks of treatment.

Medical and Biotech [MESH] Definitions

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

Diabetes mellitus induced experimentally by administration of various diabetogenic agents or by PANCREATECTOMY.

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).

A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.

A strain of Rattus norvegicus which is a model for spontaneous insulin-dependent diabetes mellitus (DIABETES MELLITUS, INSULIN-DEPENDENT).
