The Exploratory Study on the Biological Function of Dendritic Cells In Vivo Supported by Nicotinamide Mononucleotide (Vital NAD)

Study Overview
=================
Brief Summary
-----------------
The main purpose of this study is to explore the PK/PD changes of NMN and DC cells after oral NMN combined with DC cells injection in patients after tumor surgery, and evaluate the biological age of adults, TCR diversity, SiRT1 expression level, SF-36 quality of life, OS, antigen specific immune response (TAA), cytokines and so on. In this study, 20 postoperative tumor patients who meet the entry and excretion criteria were recruited to explore the clinical potential of NMN combined with DC cell vaccine.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Orally take NMN (Vital NAD) combined with DC cell vaccine injection<br>The arm is a combination of two drugs. The first NMN is a precursor of NAD+, which is used orally. DC vaccine is a kind of immune cells expanded in vitro and used by injection. | Drug: Oral NMN combined with DC cell vaccine<br>* The whole intervention cycle was treated with NMN (Vital NAD) 600mg/day for at least 50 days. During this period, the first DC cell injection was given on the 10th day, and then another DC cell injection was given at 2 weeks, 4 weeks and 6 weeks after the first injection.<br>|
