Efficacy, Safety and Tolerability of Pioglitazone-Azilsartan in Subjects With Type 2 Diabetes Mellitus
A Phase 3 Double-Blind, Randomized, Placebo-Controlled Study to Determine the Efficacy, Safety, and Tolerability of AD-4833-536 in the Treatment of Subjects With Type 2 Diabetes

The purpose of this study is to evaluate the efficacy and safety of pioglitazone-azilsartan, once daily (QD), in subjects with type 2 diabetes mellitus with poor glycemic control.

Type 2 diabetes is a chronic disease. In the United States, an estimated 21 million people have diabetes, with type 2 diabetes occurring in 90% to 95% of cases. Hypertension (high blood pressure) affects approximately 50 million individuals in the United States. The association of diabetes and hypertension is increased in this population; hypertension is more common in persons with diabetes while individuals with hypertension are 2.5 times more likely to develop diabetes than those who have normal blood pressure. As a result, more than 70% of adults with diabetes have hypertension (defined as having blood pressure greater than or equal to 130/80 mm Hg or using prescription medication for hypertension).

Patients with type 2 diabetes and hypertension are at high risk of other illnesses and death. Diabetes and hypertension are associated with insulin resistance (normal amounts of insulin are no adequate to produce a normal insulin response from fat, muscle and liver cells). and hyperinsulinemia (excess levels of insulin in the blood), which are independent risk factors for cardiovascular (heart vessel) disease. Individuals with type 2 diabetes carry a 2 to 4- time greater risk of cardiovascular disease and stroke compared with the general population. Uncontrolled hypertension also is associated with an increased risk of cardiovascular disease and stroke.

Takeda Global Research and Development Center, Inc. is developing a fixed-dose combination product, AD-4833-536. 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.
