Official title

Safety and Tolerability of the Nutritional Supplement, Nicotinamide Riboside, in Systolic Heart Failure

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Mitochondrial dysfunction has been implicated in heart failure (HF), and is associated with an imbalance in intracellular ratio of reduced nicotinamide-adenine dinucleotide (NADH) to oxidized nicotinamide-adenine dinucleotide (NAD), or the NADH/NAD ratio. In mouse models of HF, we have found that normalization of the NADH/NAD, through supplementation with NAD+ precursors, is associated with improvement in cardiac function. This Study will randomize participants with systolic HF (ejection fraction ≤40%) to treatment with the NAD precursor, nicotinamide riboside (NR) or matching placebo, uptitrated to a final oral dose of 1000mg twice daily, to determine the safety and tolerability of NR in participants with systolic HF.
