NAD Supplementation to Reduce the Incidence of Cardiac Surgery Associated Acute Kidney Injury

Overview

The purpose of this single-center, randomized, double-blinded placebo-controlled pilot trial is to demonstrate feasibility and help design a larger trial to assess the effectiveness of nicotinamide (NAM) supplementation in reducing risk of post-operative AKI in patients undergoing cardiac surgery.

This single-center, randomized, double-blind, placebo-controlled trial will serve as a pilot for a larger study that aims to assess the efficacy of nicotinamide in reducing ischemia-reperfusion injury and acute kidney injury (AKI) in patients undergoing cardiac surgery. A total of 20 patients will be randomized in a 1:1 ratio to receive either a one-time dose of NAM 3000 mg or a matching placebo on the morning of surgery. Safety assessments and clinical outcomes will be monitored for 2 days (\> 5 half-lives) . Blood samples will be collected from patients at up to two time points: preoperatively (after insertion of an arterial line \[for blood\] and intraoperatively at the end of CPB. Urine samples will also be collected at two timepoints: after insertion of the foley catheter but prior to incision, and on the morning of post-operative day 1. Discarded tissue specimens will be collected from patients at two time points: initially when excised pre-bypass, and another post-bypass, depending on the tissue availability and as a regular part of the surgery. Time points will be recorded for all the collections.
