NAD Augmentation to Treat Diabetes Kidney Disease: A Randomized Controlled Trial

A phase 2a trial randomized, double-blind, placebo-controlled, parallel group trial to determine whether NMN administration improves DKD, as indicated by a significantly greater reduction in UACR compared with placebo administration. Eligible participants will be randomized to receive either 1000 mg NMN or placebo twice daily.

Study Overview

Detailed Description

This will be two centers, randomized, double-blind, placebo-controlled, parallel group trial to determine whether βNMN, after its daily oral administration, is associated with a greater reduction in the UACR compared to placebo.

The trial will enroll community-dwelling older adults, 60 years or older, with type 2 diabetes mellitus (T2DM) and urine albumin to creatinine excretion ratio > 100 mg/ g creatinine.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Investigational Product - MIB 626
The MIB-626 will be a GMP-grade microcrystalline solid NMN mixed with inert excipients (including microcrystalline cellulose) and compressed into tablets at a dose strength of 500 mg per tablet, enabling administration of the 1,000 mg twice daily using two tablets taken twice daily.
The eligible participants will be assigned to receive either NMN or placebo using concealed block randomization in a 1:1 ratio, stratified by sex (male, female), age (60 to 75, >75 years) and trial site. The randomization list will be generated by the unblinded biostatistician using the software R (www.r-project.org), and deployed in a secure, centralized web-based application accessible to study staff following confirmation of a participant's eligibility.

  • NMN
Placebo Comparator: Placebo
Participants randomized to placebo will receive Matching placebo tablets will be provided by Metro International Biotech, LLC.
Placebo - Participants randomized to placebo will receive Matching placebo tablets will be provided by Metro International Biotech, LLC.
Other Names:
  • Placebo for NMN

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The primary endpoint is the change from baseline in UACR over the 6-month intervention period.
Time Frame: 6 months
To determine whether treatment with a microcrystalline formulation of β nicotinamide mononucleotide (βNMN) in older adults with DKD improves urinary albumin to creatinine excretion ratio (UACR), compared to placebo.
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assess the proportion of participants in the two study arms with 30% or greater reduction in UACR
Time Frame: 6 months
In supportive analysis of the primary outcome, the investigator will compare the proportion of participants in the two study arms with 30% or greater reduction in UACR
6 months
Assess the change from baseline over the 6-month intervention period in biomarkers of kidney injury.
Time Frame: 6 month
Compared to placebo treatment, NMN treatment of older adults with DKD will assess for improvements in biomarkers of kidney injury in association with DKD prognosis by measuring KIM-1 and STNFR1 combinedly.
6 month
Change from baseline in the levels of serum creatinine over 6-month intervention period
Time Frame: 6 month
To determine whether NMN treatment is associated with change in serum creatinine from baseline to 24 weeks between the two study arms.
6 month
Change from baseline in the levels of cystine C over 6-month intervention period.
Time Frame: 6 month
To determine whether NMN treatment is associated with change in cystatin C from baseline to 24 weeks between the two study arms.
6 month
To determine whether NMN treatment is associated with significantly greater improvement in muscle endurance.
Time Frame: 6 month
Assess the change from baseline in muscle endurance by exercises (reps to failure) using Keiser Machines
6 month
Assess the change from baseline in performance-based measures of function.
Time Frame: 6 month
To determine whether NMN treatment is associated with significantly greater improvement in performance based by using 6-minute walking distance measure of function.
6 month
To determine whether NMN alters the circulating biomarkers of aging that the geroscience experts have recommended.
Time Frame: 6 months
Compared to placebo treatment, NMN treatment will be assessed to identify greater changes in the circulating biomarkers of aging. the biomarkers that will be assessed are IL6 and TNFalpha
6 months
Assess the change from baseline in the levels of NMN in the peripheral blood and in the PBMCs using a validated LC-MS/MS assay.
Time Frame: 6 months
NMN treatment will be assessed to determine significant increases in blood levels of NAD and its metabolome during the 24-week intervention period. The increase in NAD levels are to be observed during the intervention period in NMN-treated subjects that will be sustained during the 12-week follow-up period (legacy effect).
6 months
Assess the change in measure of H1bac as a measure of glycemic control over the 6 months intervention period.
Time Frame: 6 months
To determine the effect of NMN treatment on Hb1ac (expressed in mg/dL) in the body as a measure of glycemic control.
6 months
Assess the change in measure of fasting glucose as a measure of glycemic control over the 6 months intervention period.
Time Frame: 6 months
To determine the effect of NMN treatment on fasting glucose in the body as a measure of glycemic control.
6 months
