Topical CBD in Joint Arthritis
Study Details
Study Description
Brief Summary
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.

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.

Outcome Measures
Primary Outcome Measures
- Change in hand strength during intervention and at follow-up. [Every 2 weeks during intervention and 1 week washout, up to 5 weeks.]
Grip, appositional, and oppositional pinch strength (kg).
- Number of participants with change in The PROMIS-29 (Patient-Reported Outcomes Measurement Information System) during intervention and at follow-up. [Every 2 weeks during intervention and 1 week washout, up to 5 weeks.]
PROMIS-29 will measure health-related quality of life and is a validated, 29 question survey divided into seven sub-domains of function including physical functioning, social function, pain interference, pain intensity, sleep, depression, and anxiety, where a higher score indicates more pain interference.
- Number of participants with change in the PROMIS upper extremity tests during intervention and at follow-up. [Every 2 weeks during intervention and 1 week washout, up to 5 weeks.]
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.
- Change in Kapandji score [Every 2 weeks during intervention and 1 week washout, up to 5 weeks.]
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.
- Change in hand range of motion [Every 2 weeks during intervention and 1 week washout, up to 5 weeks.]
metacarpal phalangeal (MP) and interphalangeal (IP) range of motion.
Secondary Outcome Measures
- Rate of side effects using novel CBD cream. [Daily during intervention and 1 week washout, up to 5 weeks.]
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.
