Clinical Trial Summary

The objective of the NAD-brain study is to determine the blood and brain pharmacokinetics of NAD replenishment therapy (NRT) using Nicotinamide Riboside (NR) or Nicotinamide Mononucleotide (NMN).

Description:

The NAD-brain study will perform a parallel assessment of NAD replenishment therapy (NRT) pharmacokinetics in the blood and brain of healthy human subjects. A total of 6-10 healthy individuals (3-5 men and 3-5 women) will undergo repeated blood sampling and 31P-MRS brain scans during two 20-day periods, each of which will start with 8 days of daily intake of Nicotinamide Riboside (NR) 600mg x 2, or Nicotinamide Mononucleotide (NMN) 600mg x 2. The two 20-day periods will be 14 days apart to allow for washout of the previous compound. Blood will be analyzed for NAD-metabolites. The simultaneous change in NAD-metabolism over time in blood and brain will be assessed and blood and brain pharmacokinetics for NRT in humans will be established.

The two 20-day periods will be 14 days apart to allow for washout of the previous compound. Blood will be analyzed for NAD-metabolites using HPLC-MS. By this approach we will measure the simultaneous change in NAD-metabolism over time in blood and brain and establish blood and brain pharmacokinetics for NRT in humans. Based on these results we will determine the optimal dosing frequency of NRT in healthy individuals.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	NAD metabolism	The change of cerebral NAD levels (measured by 31P-MRS) and of blood NAD-metabolites (measured by HPLC-MS), over time (20 days), after the administration of oral NRT with the following NAD precursors: NR 600mg x 2 daily, NMN 600mg x 2 daily.	20 days for NR and 20 days for NMN
Secondary	Interindividual differences	Descriptive analyses of interindividual differences in the time course of change in the blood NAD-metabolome and cerebral NAD increase, following the administration of oral NRT.	20 days for NR and 20 days for NMN
Secondary	Between-sex differences	Between-sex differences in the time course of change in the blood NAD-metabolome and cerebral NAD increase, following the administration of oral NRT.	20 days for NR and 20 days for NMN
