About this study

Official title: Radicle Clarity™ 24: A Randomized, Double-Blind, Placebo-Controlled Direct-to-Consumer Study Assessing the Impact of Health and Wellness Products on Cognitive Function and Related Health Outcomes

A randomized, double-blind, placebo-controlled direct-to-consumer study of health and wellness products on cognitive function and related health outcomes

Read the detailed description

This is a randomized, double-blind, placebo-controlled study conducted with adult participants, residing in the United States.

Eligible participants will (1) endorse a desire for better concentration, (2) have the opportunity for meaningful improvement (at least 20%) in their primary health outcome, and (3) express acceptance in taking a product and not knowing its formulation until the end of the study.

Participants that report a known cardiac dysfunction, liver or kidney disease may be excluded. Participants that report a known contraindication or with well-established, significant safety concerns due to illness will be excluded. Heavy drinkers and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Participants that report taking medications with a known contraindication or with well-established, significant safety concerns will be excluded.

Self-reported data are collected electronically from eligible participants for 7 weeks. Participant reports of health indicators will be collected at baseline, throughout the active period of study product use, and in a final survey. All study assessments will be electronic, there are no in-person visits or assessments for this real-world evidence study.

Being tested
Placebo Control Form 1, Clarity Active Study Product 1.1 Usage, Placebo Control Form 2, Clarity Active Study Product 2.1 Usage, Placebo Control Form 3

What is being measured

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

  1. Change in cognitive function

    Mean difference in cognition function score as assessed by Patient Reported Outcome Measurement System (PROMIS) Cognitive Function Short Form 8A (scale 8-40; where the higher scores correspond to greater cognitive function)

    Measured: 6 weeks

Secondary outcomes (3)
  1. Change in fatigue

    Mean difference in fatigue score as assessed by PROMIS Fatigue 4A (scale 4-20; where higher scores correspond to more severe fatigue)

    Measured: 6 weeks

  2. Change in sleep-related impairment

    Mean difference in sleep-related impairment score as assessed by PROMIS Sleep-Related Impairment 4A (scale 4-20; with higher scores corresponding to greater sleep-related impairment)

    Measured: 6 weeks

  3. Minimal clinical importance difference (MCID) in cognitive function

    Likelihood of achieving a MCID in cognitive function, as measured by PROMIS Cognitive Function Short Form 8A (scale 8-40; where the higher scores correspond to greater cognitive function)

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Clarity Active Study Product 1.1 Usage and Clarity Active Study Product 2.1 Usage in people with Cognitive Function, run by Radicle Science at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in cognitive function (time frame: 6 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 2 Oct 2025.
