Brief summary
The purpose of this study is to evaluate the efficacy and safety of alogliptin, once daily (QD), in adults with type 2 diabetes.
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 efficacy of alogliptin in subjects with type 2 diabetes mellitus who are inadequately controlled and who have failed treatment with diet and exercise. 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).
