Detailed Description:

Over the next decade, a marked increase in the number of adults with diabetes mellitus is expected, placing an ever-increasing burden on families and the healthcare system. A recent review of results from 2 National Health and Nutritional Examination surveys conducted in the United States found that, despite the introduction of new classes of medications for glycemic control, the percentage of adults with diabetes mellitus achieving a glycosylated hemoglobin level of less than 7% (a goal set by the American Diabetes Association) has remained relatively unchanged when data from 1999 to 2000 were compared from data from 1988 to 1994. This percentage has remained high, despite compelling evidence from a United Kingdom Prospective Diabetes Study showing that a dramatic reduction in microvascular complications and cardiovascular complications occurred when the glycosylated hemoglobin target level was indeed achieved. The rising incidence of type 2 diabetes mellitus and the limitations of the currently available treatments suggest the need for new therapies for glycemic control.

SYR-322 is a selective, orally available inhibitor of dipeptidyl peptidase IV being developed as a treatment for type 2 diabetes mellitus. Dipeptidyl peptidase IV is the primary enzyme involved in the in vivo degradation of at least 2 peptide hormones released in response to nutrient ingestion, namely glucagon-like peptide-1 and glucose-dependent insulinotropic peptide.

Pioglitazone HCl (ACTOS®) is a thiazolidinedione developed by Takeda Chemical Industries, Ltd. (Osaka, Japan). Pioglitazone HCl depends on the presence of insulin for its mechanism of action.

This study will assess the effects of SYR-322 and SYR-322 coadministered with pioglitazone HCl on postprandial lipid and lipoprotein metabolism in subjects with type 2 diabetes. Individuals who participate in this study will be required to commit to a screening visit and up to 6 additional visits at the study center. Study participation is anticipated to be about 20 weeks (or approximately 5 months). Multiple procedures will occur at each visit which may include fasting, blood collection, urine collection, physical examinations and electrocardiograms. At 3 of the visits a meal will be served that must be eaten within 10 minutes.
