Safety and Tolerability of Pioglitazone-Azilsartan in Subjects With Type 2 Diabetes

Phase 3

Terminated

• Conditions: Diabetes Mellitus, Type 2
• Interventions: Drug: Pioglitazone-Azilsartan

• Registration Number: NCT01124656
• Lead Sponsor: Takeda

Brief Summary

The purpose of this study is to determine the safety and tolerability of pioglitazone-azilsartan, once daily (QD), in patients with type 2 diabetes mellitus.

Detailed Description

AD-4833-536 is a combination of AD-4833 (pioglitazone) and TAK-536 (azilsartan). Pioglitazone is an oral antidiabetic agent that acts by reducing insulin resistance and approved for treatment of adult patients with type 2 diabetes mellitus. Azilsartan is a angiotensin II receptor blocker that modulates the renin-angiotensin-aldosterone system that regulates blood pressure. In a recent clinical trial conducted in subjects with moderately poor to poor control of their type 2 diabetes mellitus, azilsartan coadministered with pioglitazone showed a reduction in hemoglobin A1C and fasting plasma glucose levels.

After a one week screening period, subjects will be stratified to receive a starting dose of pioglitazone-azilsartan (30 mg + 20 mg or 45 mg + 20 mg).

The planned open-label treatment period was 52 weeks; however due to formulation issues, the study was prematurely discontinued and efficacy data were not analyzed.
