Impact of NMN Supplementation on CD4+ T Cell Recovery in HIV Patients With Immunological Failure

This proof-of-concept study aims to investigate the potential impact of supplementing with Nicotinamide Mononucleotide (NMN), a direct precursor of NAD+ on CD4+ T cell recovery in virologically suppressed HIV patients experiencing immunological failure on ART. We hypothesize that NMN supplementation will increase intracellular NAD+ levels, thereby improving CD4+ T cell function and potentially reversing immunological failure. A small cohort of patients will be recruited to evaluate the primary outcome of change in CD4+ T cell count from baseline to the end of the study period after receiving NMN daily for 12 weeks. Secondary outcomes including safety and tolerability, impact on pro-inflammatory markers, increase in NAD+ levels, immune activation markers and change in quality of life questionnaire scores. Patients will participate in two in person visits including a baseline and end of study with two telephone encounters. Patients will take 1,000mg NMN daily for a total of 12 weeks during which they will keep a daily log of doses taken and any side effects experienced. At all visits labs and quality of life questionnaire will be completed with complete physical exam to be done at baseline and end of study visit.
