Clinical Trial Summary

Study Description: Systemic lupus erythematosus (SLE) occurs predominantly in women and is driven by type I interferon dysregulation and neutrophil hyperresponsiveness. Neutrophils in females have reduced mitochondrial bioenergetic capacity which affects immunometabolism. Nicotinamide adenine dinucleotide (NAD)+ boosting with nicotinamide riboside blunts type 1 IFN activation in-vivo in monocytes of healthy subjects and ex-vivo in SLE subjects. These findings support the proposal of the hypothesis that NAD+ boosting by NR supplementation will modulate metabolic pathways in lupus and blunt type 1 interferon signaling. Moreover, as type 1 interferon drives endothelial dysfunction, linked to increased cardiovascular risk, the effect of NR on endothelial function will be examined. Objectives: Primary Objective: Evaluate the effect of NR vs. placebo on immunometabolic and inflammatory remodeling in female SLE subjects: Exploratory Objective: Compare and characterize myeloid cell bioenergetic and immunometabolic profiles in healthy control and SLE female subjects Endpoints: Primary Endpoint: The primary end point will be to assess the effect of NR on blunting type I IFN signaling by measuring monocytic secretion of IFN-beta secretion compared to baseline in response to placebo vs. NR supplemented in SLE study subjects. Exploratory Endpoints: Healthy control vs. SLE subjects: - Compare type I IFN transcript profiles in monocytes and neutrophils at baseline and in response to activation. - Assess cell bioenergetics including: 1) monocyte and neutrophil metabolic flux mass spectroscopy of 13C-glucose and 13Cglutamine analysis to investigate their metabolic fates; (iii) Mitochondrial oxygen consumption (using glucose, amino acid, and fatty acid substrates) and glycolysis rates. SLE baseline vs. NR/placebo supplementation: Baseline vs. 6 weeks of NR/placebo: -Assess effect of NR on bioenergetics by measuring steady-state metabolite levels comparing changes in placebo vs. NR groups in monocytes and neutrophils. Baseline vs. 12 weeks of NR/placebo: - Whole blood NAD+ levels (batched and measured at the end of study enrollment period) - Explore effects of NR on gene regulation using monocyte and neutrophils by RNA-seq and chromatin remodeling analysis. - Determine the effect of NR vs placebo on endothelial dysfunction in SLE subjects

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The primary end point will be to assess the effect of NR on blunting type I IFN signaling and cytokine secretion from placebo vs. NR supplemented subjects in monocytes comparing baseline (visit 1 to visit 3).	Type 1 IFN dysregulation is present in SLE. NAD+ boosting blunts type 1 interferon in healthy subjects in-vivo and in monocytes of SLE subjects ex-vivo. Completion of data collection time is by 01/2027.	4 years
