Purpose

The purpose of this study is to determine whether SMDS patients treated with NR at the proposed dose exhibit decreased glucose uptake in the aorta, to determine if NR treatment results in measurable changes of blood NAD+ and NR levels, to determine if aortic measurements are stable after treatment with NR and to evaluate the safety and tolerability of NR in SMDS patients.
