LOS ANGELES – ChromaDex Corp. (NASDAQ:CDXC) announced today the initiation of a preclinical study in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID), a division of the National Institutes of Health (NIH). This study will assess if administration of Niagen^® (nicotinamide riboside, or NR) can reduce viral burden and inflammation in mouse and hamster models of COVID-19. ChromaDex’s patent-protected NR is a unique nutrient that supports cellular energy production and healthy mitochondrial function through efficient restoration of NAD⁺ levels. The study is part of the ChromaDex External Research Program (CERP) in which ChromaDex’s NR ingredient and placebos are provided to researchers at no cost.

“Building upon existing cell and animal tissue models showing significant NAD⁺ depletion under COVID-19 infection, this research is a logical next step to assess whether increasing NAD⁺ levels with NR supplementation benefits the innate immune response in a preclinical COVID-19 model to reduce viral burden and/or may act as an immuno-modulator that limits the severe inflammatory response,” said Rob Fried, Chief Executive Officer at ChromaDex. “We are proud to support the NIAID to help find answers to this problem.”

This joint study is designed to assess in mice and hamsters whether NR supplementation prior to infection can reduce progression of the infection either by limiting viral replication or modulating the inflammatory response, having a positive impact on disease severity and duration, as well as increasing survival.

A recent preclinical study showed SARS-CoV-2 infected cells suffer significant NAD⁺ depletion leading to disruption of innate anti-viral immune activity, while other preclinical data suggest that modulation of inflammasome activity in immune cells by NAD⁺ may be important in the severe inflammation observed in patients infected with COVID-19. ChromaDex’s Niagen is proven to effectively restore and maintain NAD⁺ levels.

The study will be conducted at the Rocky Mountain Labs (RML) of the NIH-NIAID.

This preclinical work builds on current trans-NIAID efforts to better understand SARS-CoV-2 pathogenesis, transmission, and mechanisms of protective immunity by expanding resources and activities that support rapid development of biomedical tools to more effectively combat this disease and pandemic. Given the urgency of the public health response, studies that inform efforts to control virus spread and mitigate morbidity and mortality, including therapeutic and vaccine development, are a priority.
