NCT06544291

Brief Summary

The primary objective of this phase 2 study is to investigate the therapeutic potential of orally administered combined delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in relieving both pain and cue-induced opioid craving in people with co-occurring opioid use disorder (OUD) and chronic pain who are undergoing methadone therapy.

Outcome Measures

Primary Outcomes (2)

  • Primary Outcome Variable #1: Pain Sensitivity

    We will measure pain sensitivity using a comprehensive QST battery at baseline and approximately hourly for 8 hours. The battery includes several nociceptive modalities such as pressure, mechanical, heat, and cold stimuli. The main outcome will be a composite pain sensitivity measure, integrating data from the QST battery.

    Up to 8 hours

  • Primary Outcome Variable #2: Opioid Craving

    We will measure opioid craving using the short form Heroin Craving Questionnaire (HCQ-14) given to participants before and after a watching a visual probe task used to induce craving.

    Baseline and +180 minutes post dose

Secondary Outcomes (6)

  • Secondary Outcome Variable #1a: Cognitive/psychomotor effects (CPT)

    +180 minutes post dose

  • Secondary Outcome Variable #1b: Cognitive/psychomotor effects (HVLT)

    +180 minutes post dose

  • Secondary Outcome Variable #2a: Abuse potential of combined THC and CBD (MCP)

    +480 post dose

  • Secondary Outcome Variable #2b: Abuse potential of combined THC and CBD (DEQ)

    Up to 8 hours

  • Secondary Outcome Variable #3a: Monitor adverse events from the study medications (SAFTEE)

    Baseline ; +480 minutes post dose; One-week after last test session

  • +1 more secondary outcomes

Other Outcomes (3)

  • Central Sensitization

    Up to 8 hours

  • THC and CBD plasma levels

    Up to 8 hours

  • Influence of sex

    Up to 8 hours

Study Arms (3)

Dronabinol 5mg

  • Stated willingness to comply with all study procedures and availability for the duration of the study.
  • Male or female aged 18-65 years.
  • Co-occurring OUD (meeting DSM-5 criteria) and chronic pain (uniformly operationalized as high-impact \[occurring most days, limiting life or work activities\] non-cancer low back pain for ≥ 3 months).
  • Prior exposure to cannabis or its constituent cannabinoids at least once in the last 10 years, 1-10 times in the last 20 years, or more than 20 times in lifetime.
  • Adherence to their clinically prescribed methadone therapy, on a stable dose (30-150 mg/day ≥ 3 weeks).

  • For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner.

You may not qualify if:

  • Meeting DSM-5 criteria for cannabis use disorder and/or substance use disorders (SUDs) within the last 3 months. Participants meeting DSM-5 criteria for OUD and/or tobacco use disorder, either currently or within the last 3 months, will not be excluded per this criterion.
  • Clinically significant medical disorders as noted by the participant or through study screening procedures (e.g. liver dysfunction, as indicated by ALT and/or AST \> 1.5 times the normal limit).
  • Neurological conditions that may change the response to nociceptive stimuli (e.g., stroke, neuropathy), or that lead to loss of balance, evidenced by a neuro-sensory exam during screening.
  • Contraindications for exposure to nociceptive stimuli, such as untreated hypertension, verbally noted by participant or verified during screening procedures.
  • Abnormal screening EKG (QTc interval \>450 ms), arrythmia, or vasospastic disease.
  • Positive urine pregnancy test, or lack of birth control measures in women of childbearing potential. For males of reproductive potential refusal to use condoms or other methods to ensure effective contraception with partner.

  • Male participants who plan to donate sperm starting at screening and through 90 days after final study drug administration.
  • Females who plan to donate ova starting at screening through 28 days after final study drug administration.
  • History of primary psychotic disorders or mood disorders with psychotic features.
  • Current suicidal ideation or related behavior.
  • A physician will carefully evaluate participants for use of over-the-counter or prescription psychoactive drugs known to affect pain threshold or pain tolerance (including NSAIDS, serotonin-norepinephrine reuptake inhibitors (SNRIs) (e.g. venlafaxine, duloxetine), gabapentinoids, tricyclic antidepressants (e.g., nortriptyline, amitriptyline), anticonvulsant medications (e.g., topiramate, carbamazepine). Only participants who are on stable doses (i.e., consistent daily administration of the medication for at least three months at the same dose following the last dose change, either increase or decrease) of these medications, and whose dosing schedules allow participation in the study visits, thus excluding instances of single-dose or temporary dosing of the medication, will be eligible as determined by the sponsor-investigator. If possible, the morning dose will be administered after the study visit.
  • Current, regular use of benzodiazepines, other prescription opioids, or platelet inhibitors (e.g., clopidogrel, apixaban, ticagrelor).

  • +3 more criteria

Model Details: This phase 2 study will utilize a double-blind, placebo-controlled, crossover experimental design. We will enroll 147 participants with co-occurring OUD and chronic pain who are receiving methadone maintenance treatment and randomize them into three groups (n=49). Across three test sessions, each group will receive single doses of THC (5 mg, 10 mg, or placebo) and CBD (300 mg, 600 mg, or placebo) in a 3x3 design, with THC dose as a between-subject (parallel-group) factor and CBD dose as within-subject (crossover) factor.
