About this study

Official title: A Randomized Controlled Trial of Topical Cannabidiol for the Treatment of Thumb Basal Joint Arthritis

Rationale: CBD is commonly being used as an over-the-counter treatment for arthritis-related pain, however no clinical trial has been performed to establish efficacy.

Hypothesis: CBD is more effective than placebo for relieving pain and improving patient-reported outcomes for thumb basal joint arthritis.

Study Design: The study design with be a double-blind, randomized controlled trial with crossover. Treatment will be blinded to the subjects and investigators. Patients will be randomly assigned 2 weeks of the CBD or control and then crossover to the other condition for 2 additional weeks. Patients will apply the cream at the thumb base twice daily for 1 hour. Subjects will be advised to observe for physiologic changes, skin changes, or other adverse effects.

Read the detailed description

Study Population: 40 subjects with presenting with thumb basal joint arthritis over the age of 18 will be recruited from the UVA Hand Center.

Description of Sites/Facilities Enrolling Participants: This will be a single-site study conducted at the UVA Hand Center at the University of Virginia.

Description of Study Intervention: The study design will be a double-blind randomized control trial with crossover. Treatment will be blinded to the subjects and investigators. Patients will be randomly assigned 2 weeks of the case (CBD) or control cream and then crossover to the other cream for 2 more weeks. Patients will apply the topical cream at their thumb basal joint one time daily for 1 hour. The subjects will be advised to observe for physiologic changes, skin changes, or other adverse effects. If mild to serious adverse events are noticed, the creams will be removed immediately and appropriate care and observation will be taken. Each condition will last for 2 weeks and then subjects will be contacted by the study coordinator to facilitate crossover into the other condition. To capture any delayed-onset adverse events, including those related to skin changes that might develop after the drug is discontinued, subjects will attend a follow-up visit seven (7) days following the last dose of investigational cream.

Study Duration: This study will last one year from the beginning of subject recruitment to data analysis.

Participant Duration: Subjects will be enrolled in this study for approximately five (5) weeks from Screening until the final Study Visit.

Being tested

What is being measured

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

  1. Change in Hand Strength During Intervention and at Follow-up.

    Grip strength, kg.

    Measured: Change from baseline to 2 weeks

  2. Change in the PROMIS Upper Extremity Tests During Intervention and at Follow-up.

    The Patient Reported Outcome Information System (PROMIS) Upper Extremity Computer Adaptive Test (CAT) is a computerized assessment measuring the physical function of the upper extremity. It is scored using a T-score, and the average is 50 for the U.S. population. In a given PROMIS, a T-score above 50 represents more of the measured variable than the average. For this variable, a T-score above 50 indicates greater physical function than the average population.

    Measured: Change from baseline to 2 weeks

  3. Change in Kapandji Score

    Kapandji score (ranging 0 to 10) is validated measures in past studies as outcomes for hand disability. The Kapandji score is a tool useful for assessing the opposition of the thumb, based on where on their hand the patient is able to touch with the tip of their thumb. A score of 0 indicates no opposition, a score of 10 indicates maximal opposition.

    Measured: Change from baseline to 2 weeks

  4. Change in Hand Range of Motion

    Metacarpal phalangeal (MP) range of motion, passive extension.

    Measured: Change from baseline to 2 weeks

Secondary outcomes (1)
  1. Rate of Side Effects Using Novel CBD Cream.

    Side effects will be assessed at each encounter clinical evaluation by patient report in a Symptom Diary. All side effects thought to be secondary to CBD will be documented.

    Measured: Change from baseline to 2 weeks

A Phase 2 study testing CBD and Shea Butter in people with CBD and Hand Osteoarthritis, run by University of Virginia 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 7 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?

Change in Hand Strength During Intervention and at Follow-up. (time frame: Change from baseline to 2 weeks). The study lists 4 primary outcomes in all. 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 3 Jul 2025; AzTrials last refreshed its copy on 6 Nov 2026.
