Brief summary:
The purpose of this study is to evaluate the efficacy and safety of alogliptin, once daily (QD), combined with metformin in adults with type 2 diabetes mellitus.

Detailed description:
There are approximately 19 million people in the United States who have been diagnosed with diabetes mellitus, of which 90% to 95% are type 2. The prevalence of type 2 diabetes varies among racial and ethnic populations and has been shown to correlate with age, obesity, family history, history of gestational diabetes, and physical inactivity. Over the next decade, a marked increase in the number of adults with diabetes mellitus is expected.

Takeda is developing SYR-322 (alogliptin) for the improvement of glycemic control in patients with type 2 diabetes mellitus. Alogliptin is an inhibitor of the dipeptidyl peptidase IV enzyme. Dipeptidyl peptidase IV is thought to be primarily responsible for the degradation of 2 peptide hormones released in response to nutrient ingestion. It is expected that inhibition of dipeptidyl peptidase IV will improve glycemic (glucose) control in patients with type 2 diabetes.

The aim of the current study is to evaluate the effectiveness of alogliptin in combination with metformin in individually who are inadequately controlled on metformin alone.

Individuals who participate in this study will be required to commit to a screening visit and up to 14 additional visits at the study center. Study participation is anticipated to be about 34 weeks (or 8.5 months).
