About this study
Official title: Radicle™ Relief 2: A Randomized, Blinded, Placebo-Controlled Direct-to-Consumer Study of Health and Wellness Products on Pain and Other Health Outcomes
A randomized, blinded, placebo-controlled study assessing the impact of health and wellness products on pain and other health outcomes
Read the detailed description
This is a randomized, blinded, placebo-controlled study conducted with adult participants, age 21 and older and residing in the United States.
Eligible participants will (1) endorse a desire for less pain, (2) indicate an interest in taking a health and wellness product to potentially help their pain, and (3) express acceptance in taking a product and not knowing its formulation until the end of the study.
Participants with known liver or kidney disease, heavy drinkers, and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Those taking certain medications will be excluded.
Self-reported data are collected electronically from eligible participants over 7 weeks. Participant reports of health indicators will be collected during 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.

Questions about this trial
What is this clinical trial studying?
A study testing Relief Active Study Product 1.1 Usage, Relief Active Study Product 1.2 Usage and Relief Active Study Product 2.1 Usage in people with Pain and Neuropathic Pain, 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 11 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 6 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 pain interference (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 6 Oct 2025.
