Effect of DPP4 Inhibition on Vasoconstriction

NCT02639637

Phase 4 Completed 18 enrolled Vanderbilt University
RandomizedCrossoverQuadruple-blindBasic science

Summary

The purpose of this study is to understand how dipeptidyl peptidase IV (DPP4) inhibition in diabetics affects hemodynamic parameters and sympathetic activation in the setting of increasing concentrations of neuropeptide Y, an endogenous peptide. The central hypothesis is that DPP4 inhibition decreases degradation of neuropeptide Y, resulting in increased vasoconstriction and sympathetic activation.
