Cannabinoid Interactions With Central and Peripheral Pain Mechanisms in Osteoarthritis of the Knee

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This clinical trial is being done to better understand how daily treatment with Tetrahydrocannabinol (THC), Cannabidiol (CBD), or the combination of CBD plus THC affects knee osteoarthritis pain and other related symptoms. Consented participants will have a screening period and visit (up to 30 days to treatment start). If participants pass the screening phase, they will be randomly assigned to take one of the investigational study drugs. For this study, participants will not know when or if they are taking CBD, THC, THC plus CBD, and when or if taking placebo. Clinical pain will be assessed at multiple times throughout the study, and eligibility will be re-assessed at two weeks into the treatment period. It is possible that subjects will not be able to participate in the study after 14 days of of treatment. The treatment period will take approximately 16 weeks and then a follow-up period for approximately 2 weeks. In addition to treatment, participants will have clinical assessments, blood draws, questionnaires, daily pain diaries, sensory testing, as well as have functional connectivity magnetic resonance imaging (fcMRI).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:21 Years to 75 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Ability to read and speak English to allow for written informed consent, phenotyping, and patient-reported outcomes measures
  2. * Willingness to participate in a drug intervention trial
  3. * Diagnosis of osteoarthritis (OA) of the knee by a medical provider (confirmed by checking medical records)
  4. * Chronic knee pain, defined as moderate to severe knee pain for ≥ 6-month duration
  5. * No use of cannabis or CBD in the past in the month prior to study enrollment as per self-report
  6. * Fibromyalgia (FM) Survey Criteria score available. The questionnaire will be assessed by the research team for scoring. We will recruit enough patients to satisfy the spectrum of FM scores in four quartiles based on our previously existing data. Once a quartile is filled (approximately 40 patients enrolled), then we will not include more people from that quartile.
  7. * Self-reported normal visual acuity or correctable (with corrective lenses- glasses or contacts) to at least 20/40 for reading instructions in the MRI and visual sensitivity testing
  8. * No contraindications to magnetic resonance imaging (MRI) (for example (e.g.), metal implants)
  9. * Able to lie still on their back for 1-1.5 hours during MRI
  10. * Willingness to refrain from pain medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen for 12 hours prior to neuroimaging and Quantitative Sensory Testing (QST)
  11. * Willingness to refrain from alcohol and nicotine before QST and neuroimaging (alcohol and nicotine consumption is allowed after testing is completed)
  12. * Willingness to refrain from physical activity or exercise that would cause significant muscle and/or joint soreness for 48 hours prior to testing (routine exercise or activity that does not lead to soreness is acceptable)
  13. * Willingness to maintain a stable treatment regimen for chronic knee OA pain during the clinical trial (e.g., not initiating a new course of physical therapy)
  14. * No use of adjunctive pain medications or stable chronic daily use of adjunctive pain medications (excluding opioids)
  15. * Willingness to avoid grapefruit juice or food products for the duration of the study;
  16. * Females of reproductive potential must agree to use acceptable birth control from the screening visit and until the completion study drug administration. Sexually active male participants and/or their female partners must agree to use effective contraception during study drug treatment of the male participant. Male participants may also agree not to donate sperm during study drug treatment
  1. * Individuals who are actively applying for or in litigation for compensation or disability and other aspects associated with potential secondary gain per self-report
  2. * Inability to provide written informed consent
  3. * Previous total knee arthroplasty
  4. * Planned total knee arthroplasty within the time frame of the study
  5. * Severe physical impairment (e.g., blindness, deafness, paraplegia)
  6. * Co-morbid medical conditions that may significantly impair physical functional status (e.g., history of non-skin malignancy, or autoimmune disorder)
  7. * Use of cannabis or CBD in the past month per self-report and/or drug screen
  8. * Current opioid use (excepting tramadol) per self-report and/or drug screen
  9. * Current valproate, clobazam, or warfarin use per self-report or medical records
  10. * Current use of moderate or strong inhibitors of cytochrome p450 (CYP) enzymes CYP3A4 and CYP2C19, strong inducers of CYP3A4 or CYP2C19, moderate or strong inhibitors/inducers of CYP2C9, and narrow therapeutic index drugs (e.g., cyclosporine, amphotericin B). Participants will also not be allowed to start using these drugs during the study period if they wish to stay in the study
  11. * Self-reported allergies to sesame oil or cannabis/cannabinoids
  12. * Self-reported medical or psychiatric conditions that in the judgment of study personnel would preclude participation in this study (e.g., schizophrenia, malignancy, psychosis, suicidal ideation, history of substance abuse; note that stable anxiety and depression are not exclusions)
  13. * Pregnant or nursing
  14. * Liver failure
  15. * Self-reported liver cirrhosis
  16. * Active diagnosis or current symptoms of hepatitis by self-report
  17. * Self-reported uncontrolled diabetes
  18. * Blood pressure at screening above 180 systolic and/or 120 diastolic
  19. * Resting heart rate at screening less than 50 beats per minute (bpm) or greater than 100 bpm;
  20. * Elevated liver enzymes and bilirubin (measured via blood test at screening):
  21. * Serum total bilirubin ≥ 2.5 milligrams per deciliter (mg/dL); or,
  22. * Alanine Aminotransferase (ALT) or Aspartate Aminotransferase (AST) ≥ 3x upper limit normal (ULN); or,
  23. * Alkaline phosphatase ≥ 2 times ULN
  24. * Severe cardiovascular disease (examples: history of myocardial infarction, unstable angina, severe coronary artery disease, congestive heart failure, or severe valvular abnormalities) that is self-reported by patient or by medical record
  25. * Severe claustrophobia precluding MRI
  26. * Unable to fit in or lie comfortably in MRI
  27. * Diagnosed peripheral neuropathy

  29. * Current head injury or history of head injury (e.g., traumatic brain injury)
  30. * Any impairment, activity, behavior, or situation that in the judgment of the study team would prevent satisfactory completion of the study protocol
