Who may be able to join

  • Ages 60 and up;
  • Memory and other cognitive complaints consistent with SCD or MCI as defined by the National Institute on Aging:
  • SCD will be defined as: i. any subjective concern of change in cognitive functioning without objective evidence of cognitive impairment, and ii. complete preservation of functional abilities and independence in instrumental activities of daily living.
  • MCI will be defined as: i. a preexisting diagnosis of MCI given by a trained physician or behavioral health provider, or ii. evidence of objective impairment in cognitive functioning in one or more domain with preservation of functional abilities and independence in instrumental activities of daily living as defined by the National Institute on Aging;
  • Minimum score of 16 on t-MoCA;
  • Ability to provide direct informed consent as assessed by obtaining a score of 70% on questions 1-10, and answer 'yes' to questions 11-14 of the Informed Consent Worksheet after two attempts;

  • Any impairment in instrumental activities of daily living that would indicate a level of cognitive impairment beyond MCI as assessed by a trained rater;

  • If participating in the optional MR sub-study: Any contraindication to undergo MRI studies, such as history of cardiac pacemaker or pacemaker wires, metallic particles in the body, vascular clips in the head, prosthetic heart valves, and/or severe claustrophobia impeding ability to participate in an imaging study.

About this study

Official title: A Crossover, Randomized Block Sequence, Double-Blind, Placebo-Controlled Trial for Nicotinamide Riboside in Subjective Cognitive Decline and Mild Cognitive Impairment in Aging

In this research study we want to learn more about whether taking Niagen, a daily supplement containing a form of Vitamin B3, will improve cognitive function, mood, and daily activity in people with Subjective Cognitive Decline (SCD) or Mild Cognitive Impairment (MCI).

Read the detailed description

Over a 6 month period, we will ask study participants to take both Niagen or a placebo for 8 weeks each and complete research visits ever 4 or 8 weeks. Most research visits will involve a blood draw, cognitive testing, and mood questionnaires. We will ask you to come to our center 4-5 times to complete some study activities in-person. There will be an option to participate in a lumbar puncture sub-study, in which participants would have up to 3 lumbar punctures. There will also be an option to participate in an MRI sub-study, in which participants would have up to 3 MRIs over the course of the study. In between research visits, we will also ask the participants to wear a Fitbit activity tracker and play computerized brain games a few times a week. This will enable us to get a snapshot of each subject's functioning levels day to day and better determine whether or not the supplement is having an effect on the participant.

Sequence 1: Active Niagen, PlaceboExperimentalSubjects received 1000 mg Niagen and PBO dispensed in randomized blocks. Participants in Sequence 1 took Niagen daily for 8 weeks, followed by Placebo daily for 8 weeks.
Receives: Dietary Supplement: Niagen; Dietary Supplement: Placebo Comparator
Sequence 2: Placebo, Active NiagenExperimentalSubjects received 1000 mg Niagen and PBO dispensed in randomized blocks. Participants in Sequence 2 took Placebo daily for 8 weeks, followed by Active Niagen daily for 8 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Effect of Niagen vs PBO on Cognition as Measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).

    The primary outcome of this study will be objective measures of cognitive performance measured with the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) at baseline, crossover, and the end of study. RBANS has a mean score of 100 with a standard deviation of 15. Scores range from 40 to 160. Higher scores indicate normal cognition.

    Measured: From baseline through end of study at 16 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Niagen in people with Cognition Disorders in Old Age and Mild Cognitive Impairment, run by Steven E Arnold, MD at 1 site in United States.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Nov 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Effect of Niagen vs PBO on Cognition as Measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). (time frame: From baseline through end of study at 16 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Nov 2024.
