Summary
Type 2 diabetes is a national epidemic. Diabetes has undesirable effects on blood vessels which may contribute to heart disease. Endothelial Progenitor Cells(EPCs) are found in the blood . Research has shown that improving the survival of these special blood cells may decrease the harmful effects of diabetes on blood vessels and reduce or reverse heart disease. Saxagliptin is an FDA(Food and Drug Administration) approved prescription medicine used along with diet and exercise to lower blood sugar in people with Type 2 diabetes. It is in a class of diabetes medication called DPP-4 inhibitors. DPP-4 inhibitors have been shown to increase EPCs in patients with Type 2 diabetes.
Hypothesis: We believe poor viability and function of EPCs in early diabetes ultimately affects the repair and regeneration of the endothelium and that prompt intervention using saxagliptin with another oral hypoglycemic agent, Metformin, may reduce or reverse cardiovascular risk by improving EPC survival and function above and beyond adequate glucose metabolism control.

- Previous coronary or cerebrovascular event within 6 months of screening or active or clinically significant coronary and/or peripheral vascular disease.
- Low hematocrit 2.5X's UNL
- Kidney disease (serum creatinine levels ≥1.5 mg/dL for men, ≥1.4 mg/dL for women,Creatinine Clearance ≤50 mL/min)
- History of pancreatitis, or cancer (except basal cell carcinoma)
- Statin use started (or dose change) in the last 3 months.
- Use of oral or injectable anti-diabetic medication other than Metformin

- Active wounds or recent surgery within 3 months.
- Inflammatory disease, or current use of anti-inflammatory drugs
- triglycerides >400 mg/dL
- untreated hyper/hypothyroidism Additionally, patients who are active smokers, patients who are pregnant, nursing women, and post menopausal women who are on hormone replacement therapy will be excluded.
Patients on low dose oral contraceptives will be allowed to participate as these formulations contain lesser amount of estrogens.
