Clinical Trial Summary

This study will determine the pharmacokinetics, pharmacodynamics and safety of escalating doses of Basis following twice daily oral administration in patients with acute kidney injury (AKI). Basis is a commercially available nutritional supplement consisting of nicotinamide riboside (NR) and pterostilbene that acts to increase sirtuin activity.


Clinical Trial Description

Acute kidney injury (AKI) is common, growing in incidence, and associated with significant morbidity and mortality. Sirtuins are anti-aging enzymes that play a diverse role in cellular energy metabolism and gene regulation. Mice deficient in SIRT1 are more susceptible to developing AKI and sirtuin activation is a potential treatment for AKI.

This is a randomized, double-blind, placebo-controlled, stepwise study of escalating doses of Basis (NR/pterostilbene) in patients with AKI. The study will potentially comprise up to four Steps. The purpose of the stepwise approach is to identify the dose of Basis that achieves at least a 50% and up to 100% increase in white blood cell (WBC) content of nicotinamide adenine dinucleotide (NAD+) without side-effects.

During each Step, Basis (5 patients) or placebo (1 patient) will be given twice a day for 2 days. Patients will have frequent blood sampling performed for a 24 hour period following dosing on Day 1 and then at 48 hr. The measurements in blood will include NR/pterostilbene blood concentrations and NAD+ and NAAD (nicotinic acid adenine dinucleotide) concentrations in WBCs. ;
