A Phase 1 interventional study of Cannabidiol (CBD) and Placebo in Upper Extremity Muscle Pain, Upper Extremity Bone Pain and Upper Extremity Pain, sponsored by Brent DeGeorge. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-09.
Sponsored by Brent DeGeorge · Phase 1, Interventional, and Treatment
The goal of this clinical trial is to learn about the use of cannabidiol (CBD) capsules as a treatment for musculoskeletal pain. CBD is commonly being used as an over-the-counter treatment for musculoskeletal pain. Clinical trials have demonstrated a pain-relief benefit for hand and wrist osteoarthritis with topical CBD, however patients prefer oral CBD and no clinical trial has been performed to establish efficacy of oral CBD in humans for upper extremity musculoskeletal pain. The main questions it aims to answer are:
Is CBD more effective than placebo at relieving pain for upper extremity musculoskeletal pain ? Is CBD safe for participants with upper extremity musculoskeletal pain?
Participants will:
take 4 weeks of daily CBD capsules take 4 weeks of daily placebo capsules answer surveys about how they are feeling and functioning.
Participants will [describe the main tasks participants will be asked to do, interventions they'll be given and use bullets if it is more than 2 items].
This randomized controlled trial of CBD will investigate the therapeutic potential of CBD as an oral treatment for the treatment of pain of upper extremity musculoskeletal pain. Rationale: CBD is commonly being used as an over-the-counter treatment for musculoskeletal pain. Clinical trials have demonstrated a pain-relief benefit for hand and wrist osteoarthritis with topical CBD, however patients prefer oral CBD and no clinical trial has been performed to establish efficacy of oral CBD in humans for upper extremity musculoskeletal pain. Hypothesis: CBD is more effective than placebo for relieving pain and improving patient-reported outcomes for upper extremity musculoskeletal pain.
Study Design: The study design will be a double-blind, randomized controlled trial with crossover. Treatment will be blinded to the subjects and investigators. Patients will be randomly assigned 4 weeks of the CBD or control and then crossover to the other condition for 4 additional weeks. Patients will take one oral capsule twice daily, once in the morning and once in the evening. Subjects will be advised to observe for physiologic changes, skin changes, or other adverse effects.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.
