Saxagliptin and Atherosclerosis

• Status: Completed
• Trial end date: 2014-02-01
• Target enrollment: 0
• Participant gender: All

Summary

Dipeptidyl peptidase 4 (DPP-4) inhibitors are approved as add on therapy to improve glycaemic control in Type 2 Diabetes Mellitus (T2DM). DPP-4 inactivates the incretin hormone glucagon-like peptide 1 (GLP-1). Inhibiting the inactivation of GLP-1 leads to increased insulin- and reduced glucagon secretion after meals. DPP-4 has been shown to be present in atherosclerotic plaques. DPP-4 is a protease with substrates including cytokines and chemokines associated with atherosclerosis/inflammation.

The purpose of this study is to explore the effects of 3 months intervention with DPP-4 inhibitor saxagliptin on biomarkers related to atherosclerosis in patients with stable coronary artery disease (CAD) and T2DM, on circulating levels and on expression levels in circulating monocytes and adipose tissue.

A reduction in markers associated with atherosclerosis could indicate an antiatherosclerotic effect of DPP-4 inhibitors beyond glycaemic control alone.

Due to reduced sample size (recruitment problems) the main focus has changed and will now be on cellular aspects and gene regulation (initially secondary outcome measure).
