Efficacy and Safety of Coenzyme I for Injection on Vascular Aging.

Emerging evidence identifies vascular aging independently predicting cardiovascular events, yet effective clinical interventions remain lacking. Nicotinamide adenine dinucleotide (NAD+) is an essential cofactor whose levels decline with age, and preclinical studies suggest that boosting NAD+ can improve vascular function and structure. Preliminary clinical studies in healthy older adults indicate that supplementation with NAD+ precursors, such as nicotinamide riboside(NR) or nicotinamide mononucleotide (NMN), can reduce arterial stiffness as measured by pulse wave velocity (PWV). However, whether NAD+ supplementation can improve vascular endothelial function and exert anti-stiffening effects in patients who have already developed measurable arterial stiffness remains unknown. Based on this evidence, the investigator hypothesize that the Coenzyme I for Injection will reverse vascular aging in older adults with established arterial stiffening.

Evaluation of the Impact of an Alteration of NAD+ Metabolism on the Renal Prognosis of Patients Admitted to Intensive Care (NI-AKI)

Among all patients admitted to intensive care, it is estimated that more than half of them are exposed during their stay to acute renal failure (ARF). Impacting the vital prognosis to short term, the occurrence of renal failure is not without consequences in intensive care survivors, presenting an increased risk of death mainly mediated by an excess risk with regard to chronic kidney disease and/or certain cardiovascular pathologies. Malnutrition, particularly vitamin deficiency, has already been reported as a risk factor for AKI. Studies on two models (animal and human) have recently highlighted the importance of NAD+ production failure in the onset of renal failure. NAD+ synthesis can be done from tryptophan or via a salvage pathway from vitamin PP. In a phase 2 study in patients undergoing cardiac surgery, vitamin B3 supplementation was accompanied by a reduction in the occurrence of AKI and a limitation of the duration / intensity of renal dysfunction. This innovative research aims to identify an alteration in the metabolic pathway of NAD+ production as a risk factor for AKI in intensive care patients. This would be the first study to address this issue in this specific population. The main objective of this research is to describe the association between the urinary Quinolinate/Tryptophan ratio on admission and the occurrence of acute renal failure in patients admitted to intensive care unit.

Comparison of Two Qualia NAD⁺ Formulations on Intracellular NAD⁺ Levels

This is a randomized, double-blind, placebo-controlled, parallel-group study evaluating the effects of two distinct Qualia NAD⁺ formulations on intracellular NAD⁺ levels in healthy adults aged 35-75 years. Approximately 180 participants will be randomized to one of three study arms: Qualia NAD⁺ version 1, Qualia NAD⁺ version 2, or placebo. Each participant will take two capsules of their assigned product once daily in the morning, with or without food, over a 28-day period. The primary outcome is the change in intracellular NAD⁺ levels, assessed via at-home finger-stick blood collection at baseline and study completion. Secondary endpoints include changes in aging-related symptoms (AMFS scores), health-related quality of life (RAND SF-36), and evaluation of safety and tolerability. All assessments, including electronic questionnaires, are completed remotely without in-person visits.

Nicotinamide Riboside Impact on Extracellular Nicotinamide Adenine Dinucleotide (NAD+)

The investigation is a clinical study in which the impact of taking the dietary supplement nicotinamide riboside (NR) on the concentration of extracellular nicotinamide adenine dinucleotide (eNAD+) in human plasma over time will be determined. The study will be conducted in a randomized, double-blinded, and placebo-controlled manner.
